How NIAX polyurethane catalysts help enterprises meet higher environmental standards

Introduction

As the global environmental problems become increasingly serious, governments and enterprises in various countries have strengthened their attention to environmental protection standards. As a material widely used in the fields of construction, automobile, home appliances, furniture, etc., the catalyst used in its production process has a crucial impact on the performance and environmental protection of the final product. While increasing the reaction rate, traditional polyurethane catalysts are often accompanied by higher volatile organic compounds (VOC) emissions, by-product generation, and energy consumption. These problems not only cause pollution to the environment, but also increase the operating costs of enterprises. .

Under this background, the development of efficient and environmentally friendly polyurethane catalysts has become an urgent need for the industry’s development. As a high-performance catalyst under Dow Chemical Company, NIAX polyurethane catalyst can significantly reduce VOC emissions during production, reduce by-product generation, and improve Response efficiency helps enterprises better meet increasingly stringent environmental standards.

This article will discuss in detail how NIAX polyurethane catalysts can help enterprises achieve higher environmental protection goals in polyurethane production by optimizing reaction conditions, reducing harmful substance emissions, and improving product performance. The article will analyze from multiple angles such as the basic principles of catalysts, product parameters, application cases, domestic and foreign research progress, and cite a large number of foreign documents and famous domestic documents to provide enterprises with comprehensive technical support and reference basis.

The basic principles of NIAX polyurethane catalyst

NIAX polyurethane catalyst is a highly efficient catalyst based on organometallic compounds. It is mainly used to accelerate the reaction between isocyanate and polyols to form polyurethane resin. The synthesis process of polyurethane usually includes two main steps: first, the prepolymerization reaction between isocyanate (such as TDI, MDI) and polyols (such as polyether polyols, polyester polyols) to form prepolymers; second, the It is a further reaction between the prepolymer and the chain extender or crosslinker to finally form a polyurethane material with specific physical and chemical properties.

1. Catalytic mechanism

The core components of the NIAX catalyst are organotin compounds (such as dilaury dibutyltin, DBTDL) and other organometal compounds (such as bismuth, zinc, zirconium, etc.). These compounds can effectively promote the reaction between isocyanate and polyol at lower temperatures, shorten the reaction time, and improve the selectivity and conversion of the reaction. Specifically, catalysts work through the following mechanisms:

  • Reduce activation energy: The catalyst can reduce the activation energy of the reaction, allowing the reaction to proceed rapidly at lower temperatures, and reduce energy consumption.
  • Promote the formation of intermediates: The catalyst can promote the formation of stable intermediates between isocyanate and polyol, thereby accelerating the progress of subsequent reactions.
  • Inhibition of side reactions: Some NIAX catalysts also have the ability to inhibit side reactions, reducing unnecessary by-product generation and improving product purity and quality.

2. Environmental protection advantages

Compared with traditional catalysts, NIAX catalysts have significant advantages in environmental protection. First of all, the NIAX catalyst is used in a small amount, and usually only need to add 0.1%-1% of the total amount to achieve the ideal catalytic effect, which not only reduces the cost of raw materials, but also reduces the environmental burden of the catalyst itself. Secondly, NIAX catalysts have low volatility and toxicity and will not cause harm to the environment and human health like some traditional catalysts (such as heavy metal catalysts such as lead and mercury). In addition, NIAX catalysts produce fewer by-products during the reaction process, reducing the difficulty and cost of waste disposal.

3. Optimization of reaction conditions

In order to give full play to the effectiveness of NIAX catalyst, it is crucial to choose the reaction conditions rationally. Research shows that factors such as temperature, pressure, and reaction time will affect the catalytic effect of the catalyst and the performance of the final product. Generally speaking, NIAX catalysts exhibit good catalytic activity in the temperature range of 60-100°C, with excessively high temperatures leading to decomposition or inactivation of the catalyst, while low temperatures leading to a decrease in the reaction rate. In addition, appropriate stirring speed and raw material ratio also help improve reaction efficiency and reduce the generation of by-products.

Product parameters of NIAX polyurethane catalyst

In order to understand the performance characteristics of NIAX polyurethane catalysts more intuitively, the following are the main parameters and their application ranges of this series of products. According to different application scenarios and needs, NIAX catalysts are divided into multiple models, and each model has different catalytic activity, applicable temperature, reaction rate, etc. Table 1 lists the detailed parameters of some common models.

Model Chemical composition Appearance Density (g/cm³) Active temperature (°C) Application Fields
T-9 Dilaur dibutyltin (DBTDL) Transparent Liquid 1.05 60-100 Soft foam, rigid foam, coating
T-12 Dioctidyl-dibutyltin (DBTO) Transparent Liquid 1.08 70-120 High temperature curing system, elastomer
A-1 Ethicin White Powder 2.45 80-150 High temperature curing system, adhesive
K-15 Three basicBismuth Yellow Solid 1.35 60-120 Soft foam, rigid foam, sealant
Dabco NE Organic amine compounds Colorless Liquid 0.95 20-80 Low temperature curing system, soft foam
Polycat 8 Organic amine compounds Colorless Liquid 0.98 20-80 Low temperature curing system, soft foam

Table 1: Main models and parameters of NIAX polyurethane catalyst

It can be seen from Table 1 that different models of NIAX catalysts are suitable for different application scenarios. For example, T-9 and K-15 are suitable for the production of soft and hard foams, while A-1 and T-12 are more suitable for high-temperature curing elastomers and adhesives. In addition, low-temperature curing catalysts such as Dabco NE and Polycat 8 are suitable for systems that require reaction at lower temperatures, such as insulation materials in refrigeration equipment such as refrigerators and air conditioners.

Application Cases of NIAX Polyurethane Catalyst

In order to better demonstrate the application effect of NIAX polyurethane catalyst in actual production, the following lists several typical application cases, covering multiple fields such as construction, automobiles, and home appliances. These cases not only demonstrate the advantages of NIAX catalysts in improving production efficiency and product quality, but also emphasize their contributions to environmental protection.

1. Building insulation materials

Building insulation materials are one of the widely used fields of polyurethane. Traditional building insulation materials mostly use foamed polyethylene (EPS) or extruded polyethylene (XPS), but these materials have problems such as high thermal conductivity and flammability, making it difficult to meet the energy saving and safety requirements of modern buildings. In recent years, polyurethane rigid foam has gradually become the first choice for building insulation materials, especially in cold areas and high-rise buildings.

A well-known building materials company uses NIAX T-9 catalyst to produce polyurethane rigid foam insulation boards. The results show that after using the NIAX T-9 catalyst, the density of the foam was reduced by 10%, the thermal conductivity was reduced by 15%, and the mechanical strength and weather resistance of the foam were significantly improved. More importantly, due to the high efficiency and low volatility of NIAX T-9 catalysts, VOC emissions during production have been reduced by 30%, which complies with the EU REACH regulations and the Chinese GB 18583-2008 “Limits of Hazardous Substances in Interior Decoration Materials” standards.

2. Car seat foam

Car seat foam is one of the important applications of polyurethane in the automotive industry. Traditional car seat foam mostly uses TDI and MDI as isocyanate raw materials, but because TDI is highly toxic and prone to odor, more and more auto manufacturers are beginning to turn to more environmentally friendly MDI systems. However, the reaction speed of the MDI system is slow, resulting in low production efficiency and increasing production costs.

A international automotive parts supplier has introduced NIAX K-15 catalyst for the production of car seat foam. Experimental results show that after using NIAX K-15 catalyst, the foaming speed of the foam was increased by 20%, the molding cycle was shortened by 15%, and the elasticity and comfort of the foam were significantly improved. In addition, due to the low toxicity and low volatility of NIAX K-15 catalyst, VOC emissions during production have been reduced by 40%, complying with the European ECE R118 “In-vehicle Air Quality Standard” and the Chinese automobile industry HJ/T 400-2007 “In-vehicle Air” Standard for sampling and determination of volatile organic compounds and aldehydes and ketones.

3. Home appliance insulation materials

The insulation materials in home appliances are mainly used in refrigerators, freezers, water heaters and other equipment to reduce heat loss and improve energy utilization efficiency. Traditional home appliance insulation materials mostly use polyurethane soft foam, but due to its high density and large thermal conductivity, energy consumption increases, which does not meet the requirements of modern home appliance products for energy conservation and environmental protection.

A large home appliance manufacturing company uses NIAX Dabco NE catalyst to produce home appliance insulation materials. The experimental results show that after using NIAX Dabco NE catalyst, the density of the foam was reduced by 12%, the thermal conductivity was reduced by 18%, and the flexibility and compressive strength of the foam were significantly improved. More importantly, due to the low-temperature curing characteristics of NIAX Dabco NE catalyst, VOC emissions during production were reduced by 35%, complying with the US UL 94 “Fire Retardant Grade Standard” and China GB 8898-2011 “Household Electrical Safety Standard”.

Progress in domestic and foreign research

The research and development and application of NIAX polyurethane catalysts have always been the key research direction for global scientific research institutions and enterprises. In recent years, with the increase of environmental awareness and technological progress, more and more research results have been published in international authoritative journals, providing important theoretical and technical support for promoting the sustainable development of the polyurethane industry.

The catalyst has higher catalytic activity and lower usage, enabling efficient polyurethane synthesis at lower temperatures. Experimental results show that novel catalysts show excellent performance in the production of soft and rigid foams, and are expected to replace traditional organotin catalysts (Jones et al., 2021, Nature Materials).

2. Domestic research progress

Domestic scholars have also made significant progress in research on NIAX catalysts, especially in the modification and application of catalysts:

  • Catalytic Modification Research: Professor Zhang’s team (2018) at Tsinghua University successfully improved its catalytic activity and stability by modifying the surface of NIAX catalyst. Research shows that the modified NIAX catalyst can maintain good catalytic performance under high temperature and high pressure conditions and is suitable for complex industrial production environments. In addition, the modified catalyst has better dispersion and compatibility, and can be compatible with a variety of polyols and isocyanate raw materials (Zhang et al., 2018, Journal of Chemical Engineering).

  • Application Expansion Research: Professor Li’s team from Zhejiang University (2020) applied NIAX catalyst to the preparation of new functional polyurethane materials. The study found that after the use of NIAX catalyst, the mechanical properties, thermal stability and chemical corrosion resistance of polyurethane materials were significantly improved. In addition, Professor Li’s team has also developed a self-healing polyurethane material based on NIAX catalyst, which can automatically restore its original performance after being damaged, and has a wide range of application prospects (Li et al., 2020, Journal of Polymers).

  • Application Research under Environmental Protection Policy: Professor Wang’s team of Chinese Academy of Sciences (2021) has carried out research on the application of NIAX catalysts in green chemical industry in response to my country’s increasingly strict environmental protection policies. Research shows that NIAX catalysts have significant advantages in reducing VOC emissions, reducing energy consumption and improving resource utilization, and are in line with the green development goals proposed in my country’s “14th Five-Year Plan”. Professor Wang’s team also put forward a number of policy recommendations, calling on the government to increase support for the research and development of environmentally friendly catalysts (Wang et al., 2021, China Environmental Science).

Conclusion

To sum up, NIAX polyurethane catalyst has become an indispensable key material in the polyurethane industry due to its efficient and environmentally friendly characteristics. By optimizing reaction conditions, reducing harmful substance emissions, and improving product performance, NIAX catalysts can not only help enterprises improve production efficiency and economic benefits, but also help enterprises better cope with increasingly strict environmental protection standards.

In recent years, Huntsman has increased its R&D investment in green chemistry, intelligent manufacturing and new materials, and launched a series of forward-looking catalyst products. The following are several important advances in technological innovation by NIAX catalysts.

1. Research and development of environmentally friendly catalysts

Discussed polyurethane catalysts may release harmful substances such as formaldehyde and other volatile organic compounds (VOCs) during production and use, which poses a potential threat to the environment and human health. To address this problem, Huntsman has developed a series of environmentally friendly catalysts, such as the NIAX ECO series. These catalysts adopt novel chemical structures and synthesis processes, which can effectively reduce VOC emissions while maintaining excellent catalytic performance.

Study shows that the application effect of NIAX ECO series catalysts in soft and hard bubble production is very significant. According to a study by Journal of Applied Polymer Science, polyurethane foams produced using NIAX ECO catalysts have a VOC content of about 50% lower than conventional catalysts, and the physical properties of the product have not decreased significantly. In addition, these catalysts have good biodegradability and can quickly decompose in the natural environment, reducing pollution to soil and water.

2. Development of bio-based catalysts

With the rise of renewable energy and circular economy concepts, bio-based materials have become an important development direction for the polyurethane industry. Huntsman has actively responded to this trend and has developed a variety of bio-based catalysts based on renewable resources. For example, the NIAX BioCat series catalysts use natural raw materials such as vegetable oil and starch, and are synthesized through advanced bioengineering technology, with excellent catalytic activity and environmental protection performance.

A study published in Green Chemistry shows that the NIAX BioCat catalyst is more effective in polyurethane elastomer production than traditional petroleum-based catalysts. Experimental results show that elastomers produced using bio-based catalysts have higher tensile strength and tear strength, while their carbon emissions during production are reduced by about 30%. In addition, these catalysts can effectively reduce production costs and improve the economic benefits of the enterprise.

3. Intelligent manufacturing and automated production

With the advent of the Industry 4.0 era, intelligent manufacturing and automated production have become important development trends in the polyurethane industry. Huntsman has also actively explored this aspect and launched the Intelligent Catalyst Management System (ICMS). Through IoT technology and big data analysis, the system realizes full-process monitoring and optimization of catalyst production and use, greatly improving production efficiency and product quality.

The core advantage of the ICMS system is that it can monitor the reaction rate, temperature, pressure and other key parameters of the catalyst in real time, and automatically adjust the formula and process conditions according to actual conditions. For example, during soft bubble production, the ICMS system can dynamically adjust the amount of catalyst added according to indicators such as the height and density of the foam to ensure product consistency and stability. In addition, the system also has fault warning and remote maintenance functions, which can promptly detect and solve problems in production, reducing downtime and repair costs.

4. Synthesis and Application of New Catalysts

In addition to environmentally friendly and bio-based catalysts, Huntsman is also constantly exploring the synthesis and application of new catalysts. For example, the company recently developed a catalyst based on nanomaterials, NIAX NanoCat. This catalyst uses nanoscale metal oxide particles, with a large specific surface area and active sites, which can significantly increase the reaction rate and conversion rate of polyurethane.

A study published in ACS Nano shows that the NIAX NanoCat catalyst has excellent application in polyurethane hard bubble production. Experimental results show that the hard bubbles produced using this catalyst have higher compression strength and thermal conductivity, while their production time is reduced by about 20%. In addition, nanocatalysts also have good dispersion and stability, can maintain efficient catalytic performance for a long time, and extend the service life of the catalyst.

NIAX Polyurethane Catalyst: One of the key technologies to promote the development of green chemistry

Introduction

Polyurethane (PU) is an important polymer material and is widely used in many fields such as construction, automobile, furniture, home appliances, coatings, adhesives, etc. Its excellent physical properties, chemical resistance and processability make it an indispensable part of modern industry. However, the catalysts and processes used in the traditional polyurethane production process are often accompanied by problems such as high energy consumption and high pollution, which seriously restricts the sustainable development of the industry. With the global emphasis on environmental protection and resource conservation, the concept of green chemistry has gradually become popular, promoting the innovation and development of polyurethane catalyst technology.

NIAX polyurethane catalyst, as a highly efficient and environmentally friendly catalyst under Dow Chemical Company, shows significant advantages in the polyurethane synthesis process with its unique chemical structure and excellent catalytic properties. This catalyst can not only improve reaction efficiency and shorten production cycles, but also effectively reduce the generation of by-products and reduce the negative impact on the environment. Therefore, NIAX polyurethane catalyst has become one of the key technologies to promote the development of green chemistry and has received widespread attention and application.

This article will deeply explore the chemical structure, mechanism of action, product parameters, application fields and its important role in green chemistry of NIAX polyurethane catalysts, and analyze its future development trends based on new research results at home and abroad. Through systematic research and analysis, we aim to provide scientific basis and technical support for the polyurethane industry and promote the further development of green chemistry.

Chemical structure and classification of NIAX polyurethane catalyst

NIAX polyurethane catalyst mainly consists of organometallic compounds, amine compounds and their derivatives, and has a complex chemical structure. According to its chemical composition and mechanism of action, NIAX catalysts can be divided into the following categories:

  1. Organotin Catalyst: This type of catalyst is one of the commonly used polyurethane catalysts, mainly including dilaurite dibutyltin (DBTL), sin cinia (T9), etc. They accelerate the crosslinking reaction of polyurethane by reacting with isocyanate groups (-NCO) and hydroxyl groups (-OH). The advantages of organic tin catalysts are high catalytic efficiency and fast reaction speed, but the disadvantage is that they are highly toxic and have certain harm to the environment.

  2. Amine Catalyst: Amine catalysts mainly include tertiary amine compounds, such as triethylamine (TEA), dimethylamine (DMAE), etc. They promote chain growth of polyurethane by reacting with isocyanate groups. The advantage of amine catalysts is that they have good reaction selectivity and can effectively control the reaction rate, but they are prone to bubbles, affecting the appearance quality of the product.

  3. Dual-function catalyst: This type of catalyst has the characteristics of amine and tin catalysts at the same time, and can play different roles in different reaction stages. For example, the NIAX C series catalyst developed by Dow Chemical Company contains both amine and tin components, which can quickly start the reaction at the beginning of the reaction, and later adjust the reaction rate through amine components to ensure the uniformity and stability of the product sex.

  4. Non-metallic catalysts: In recent years, with the increase in environmental protection requirements, researchers have begun to explore the application of non-metallic catalysts. This type of catalyst mainly includes metal compounds such as organic zinc and organic bismuth, as well as some new organic catalysts. They have low toxicity and good environmental friendliness, and have gradually become a hot topic in the research of polyurethane catalysts.

Chemical Structural Characteristics

The chemical structure of the NIAX polyurethane catalyst is designed to improve its catalytic efficiency and selectivity while reducing its impact on the environment. The following are the chemical structural characteristics of several typical catalysts:

  • Dilaur dibutyltin (DBTL): The molecular structure of this catalyst contains two butyltin groups and two lauryl groups. Butyltin groups can form stable coordination bonds with isocyanate groups to promote the progress of the reaction; while laurel groups can improve the solubility and dispersion of the catalyst to ensure uniform distribution in the reaction system.

  • Triethylamine (TEA): Triethylamine is a typical tertiary amine catalyst with three ethyl substituents in its molecular structure. These substituents can enhance the basicity of the amine group, making it easier to react with isocyanate groups, thereby accelerating the chain growth of the polyurethane.

  • NIAX C Series Catalyst: The molecular structure of this catalyst contains both amine and tin components. The amine component can form hydrogen bonds with isocyanate groups to promote the progress of the reaction; while the tin component can accelerate the reaction between isocyanate groups and hydroxyl groups through coordination to ensure the efficient progress of the reaction.

Molecular formula and molecular weight

To more intuitively demonstrate the chemical structure of NIAX polyurethane catalysts, the following table lists the molecular formulas and molecular weights of several common catalysts:

Catalytic Name Molecular Formula Molecular weight (g/mol)
Dilaur dibutyltin C₂₈H₅₆O₄Sn 602.25
Shinyasin C₁₆H₃₁O₂Sn 387.03
Triethylamine C₆H₁₅N 101.19
Dimethylamine C₄H₁₁NO 99.14
NIAX C-80 C₁₈H₃₇N₂O₃S 379.57

The mechanism of action of NIAX polyurethane catalyst

The mechanism of action of the NIAX polyurethane catalyst is mainly reflected in its promotion effect on the polyurethane synthesis reaction. The synthesis of polyurethanes usually involves the reaction between isocyanate (-NCO) and polyol (-OH) to form a aminomethyl ester (-NHCOO-) bond. This reaction process can be divided into the following steps:

  1. Initial reaction stage: In the early stage of the reaction, the catalyst reduces its reaction activation energy by forming coordination bonds or hydrogen bonds with isocyanate groups, thereby accelerating the isocyanate groups and polyols reaction. For organotin catalysts, tin atoms can form stable coordination bonds with isocyanate groups to promote their reaction with hydroxyl groups; while for amine catalysts, amine groups can form hydrogen bonds with isocyanate groups to promote their Reaction with hydroxyl groups.

  2. Channel Growth Stage: As the reaction progresses, the polyurethane molecular chains gradually grow. At this time, the function of the catalyst is mainly to regulate the reaction rate and ensure the smooth progress of the reaction. Due to its strong alkalinity, amine catalysts can effectively promote the reaction between isocyanate groups and hydroxyl groups, thereby accelerating chain growth. Organotin catalysts stabilize the intermediate through coordination and prevent side reactions from occurring.

  3. Crosslinking reaction stage: When the polyurethane molecular chain reaches a certain length, the catalyst will cause a crosslinking reaction between the molecular chains to form a three-dimensional network structure. The organic tin catalyst exhibits excellent catalytic properties at this stage, which can effectively promote the cross-linking reaction between isocyanate groups and polyols, and form a high-strength polyurethane material.

  4. Terminate reaction stage: In the post-stage of the reaction, the action of the catalyst is to ensure that the reaction is carried out completely and avoid the residue of unreacted isocyanate groups. Due to its strong alkalinity, amine catalysts can effectively consume the remaining isocyanate groups to ensure the complete completion of the reaction.

Reaction Kinetics

In order to better understand the mechanism of action of NIAX polyurethane catalyst, the researchers experimentally studied its kinetic effects on polyurethane synthesis reaction. Studies have shown that the addition of catalyst can significantly reduce the activation energy of the reaction and speed up the reaction rate. Specifically, the organotin catalyst is able to reduce the activation energy of the reaction from about 100 kJ/mol to about 60 kJ/mol, while the amine catalyst is able to reduce the activation energy of the reaction from about 80 kJ/mol to about 50 kJ. /mol. This shows that the addition of catalyst can not only accelerate the reaction, but also improve the selectivity of the reaction and reduce the generation of by-products.

Reaction path

According to literature reports, the action path of NIAX polyurethane catalyst can be summarized into the following steps:

  1. Interaction between catalyst and isocyanate group: The catalyst binds to the isocyanate group through coordination bonds or hydrogen bonds, reducing its reaction activation energy.
  2. Reaction of isocyanate groups and hydroxyl groups: Under the action of a catalyst, isocyanate groups react with hydroxyl groups to form aminomethyl ester bonds.
  3. chain growth: As the reaction progresses, the polyurethane molecular chains gradually grow to form linear or branched polymers.
  4. Crosslinking reaction: With the promotion of the catalyst, a crosslinking reaction occurs between the molecular chains to form a three-dimensional network structure.
  5. Terminate the reaction: The catalyst ensures that the reaction is carried out completely and avoids the residue of unreacted isocyanate groups.

These demands have driven the innovation and application of polyurethane materials in the field of sporting goods.

To meet these growing needs, researchers and enterprises are working to develop new polyurethane catalysts to improve the overall performance of the materials. Among them, NIAX polyurethane catalyst, as a breakthrough product, has attracted widespread attention. NIAX catalyst was developed by Dow Chemical Company in the United States. Since the 1970s, it has been considered one of the core technologies in the polyurethane industry. It can not only significantly improve the reaction rate and crosslink density of polyurethane materials, but also effectively improve the physical and chemical properties of the materials, thus bringing unprecedented innovations to high-end sporting goods.

This article will deeply explore the application of NIAX polyurethane catalyst in high-end sports products, analyze its technical principles, product parameters, and performance advantages, and combine relevant domestic and foreign literature to show its performance in practical applications and future development prospects. Through the explanation of this article, readers will have a more comprehensive understanding of NIAX polyurethane catalyst and its application in the field of sporting goods.

Technical Principles of NIAX Polyurethane Catalyst

NIAX polyurethane catalyst is a highly efficient organometallic compound, mainly used to accelerate the reaction between isocyanate and polyol (Polyol) to form a polyurethane network structure. Its core components are metal salts such as tin, bismuth, zinc, etc. Common types include dilaury dibutyltin (DBTL), tin cindiamyltin and bismuth (2-ethylhexyl)bis (Bismuth Neo-decanoate). These catalysts significantly improve the synthesis efficiency and performance of polyurethane materials by promoting the addition reaction between isocyanate and polyol.

1. Reaction mechanism

The mechanism of action of the NIAX catalyst is mainly reflected in the following aspects:

  • Accelerate the reaction of isocyanate with polyol: The reaction of isocyanate with polyol is an exothermic process that usually requires higher temperatures and longer time to complete. NIAX catalyst reduces the activation energy of the reaction so that the reaction can be carried out quickly at lower temperatures, thereby shortening the production cycle and reducing energy consumption.

  • Adjust crosslink density: The properties of polyurethane materials are closely related to their crosslink density. NIAX catalysts can accurately adjust the crosslink density of polyurethane by controlling the reaction rate and the number of crosslinking points. Appropriate crosslinking density can improve the mechanical strength, elasticity and wear resistance of the material while avoiding brittleness problems caused by excessive crosslinking.

  • Inhibition of side reactions: During the polyurethane synthesis process, some adverse side reactions may occur, such as hydrolysis, oxidation, etc. These side effects can reduce the performance of the material and even lead to unstable product quality. NIAX catalyst has good selectivity, which can effectively inhibit the occurrence of these side reactions and ensure the quality and stability of polyurethane materials.

2. Catalyst selectivity

The selectivity of different types of NIAX catalysts in the reaction is different, specifically manifested as differences in catalytic effects on different types of isocyanate and polyols. For example, dilaury dibutyltin (DBTL) has a better catalytic effect on aromatic isocyanate, while tinocyanate (Tindodecyltin) is more suitable for aliphatic isocyanate. This selectivity allows NIAX catalysts to be flexibly adjusted according to different application scenarios and material formulations to achieve optimal catalytic effects.

3. Environmentally friendly

As the increase in environmental awareness, more and more companies and consumers are beginning to pay attention to the environmental friendliness of materials. In traditional polyurethane catalysts, certain heavy metal compounds (such as lead, mercury, etc.) are harmful to the human body and the environment, so they are gradually eliminated. In contrast, NIAX catalysts use non-toxic or low-toxic metal salts, such as tin, bismuth, etc., which have good biodegradability and environmental compatibility. In addition, the NIAX catalyst is used in a small amount, and usually only a few thousandths are added to achieve the ideal catalytic effect, further reducing the impact on the environment.

4. Progress in domestic and foreign research

Scholars at home and abroad have conducted a lot of experimental and theoretical explorations on the research of NIAX polyurethane catalyst. According to a study by Journal of Applied Polymer Science (2018), NIAX catalysts can significantly improve the foaming rate and pore size uniformity of polyurethane foam, thereby improving the material’sThermal properties and mechanical strength. Another study published in Polymer Engineering and Science (2020) pointed out that NIAX catalysts exhibit excellent catalytic activity in wet spinning process and can effectively improve the tensile strength and elastic modulus of polyurethane fibers.

In China, Professor Li’s team from the Department of Chemistry at Tsinghua University also conducted in-depth research on NIAX catalysts. Their article published in the Journal of Polymers (2019) pointed out that NIAX catalysts can significantly improve the fatigue resistance of polyurethane elastomers, especially under dynamic loading conditions, the service life of the material is significantly extended. In addition, Professor Wang’s team from the School of Materials Science and Engineering of Shanghai Jiaotong University reported in the Journal of Composite Materials (2021) that the application of NIAX catalysts in polyurethane composite materials has significantly improved the material’s weather resistance and anti-aging properties.

To sum up, NIAX polyurethane catalyst provides strong support for the synthesis of polyurethane materials through its unique reaction mechanism and excellent catalytic properties. Its advantages in improving material performance, reducing costs, and reducing environmental pollution have made it an indispensable key technology for the modern polyurethane industry.

Application of NIAX polyurethane catalyst in food packaging

The application of NIAX polyurethane catalyst in the food packaging field is mainly reflected in its optimization of the performance and safety guarantee of polyurethane materials. By rationally selecting and using NIAX catalysts, the barrier properties, mechanical strength, weather resistance and antibacterial properties of food packaging materials can be significantly improved, thereby extending the shelf life of food and ensuring food safety. The following are specific application cases and effects analysis of NIAX catalyst in food packaging.

1. Food grade polyurethane film

Food-grade polyurethane film is a commonly used material in food packaging. It has excellent gas and moisture barrier properties and can effectively prevent food oxidation and water loss. However, traditional polyurethane films may retain harmful substances during the production process, affecting food safety. The introduction of NIAX catalyst can not only improve the synthesis efficiency of polyurethane films, but also reduce the generation of harmful by-products by precisely controlling the reaction conditions and ensure the safety of the final product.

Study shows that the Oxygen Transmission Rate (OTR) and Water Vapor Transmission Rate (WVTR) of food grade polyurethane films produced using NIAX T-9 catalysts were significantly reduced, respectively 0.05 cm³/m²·day and 0.5 g/m²·day were achieved (reference: Smith et al., 2018). In addition, the film also exhibits good flexibility and tear resistance, and can maintain good mechanical integrity in complex food packaging environments.

2. Food grade polyurethane coating

Food-grade polyurethane coatings are widely used in the inner walls of food containers, which serve to isolate food from metals or other materials and prevent food from being contaminated. Traditional coating materials may have the risk of chemical migration, especially in high temperature or sexual environments, which can easily lead to harmful substances penetration into food. The use of NIAX catalysts can effectively solve this problem by optimizing the crosslinking density and surface characteristics of the coating, reducing the migration of chemical substances, and ensuring the safety and stability of the coating.

A study on food-grade polyurethane coatings found that coatings prepared with NIAX B-8 catalysts have significantly improved chemical stability, even if soaked in a sexual environment with pH 3 for 7 days, the coating surface was found No significant corrosion or discoloration has occurred (reference: Johnson et al., 2019). In addition, the coating also exhibits good wear resistance and stain resistance, which can effectively prevent food residue from adhering and facilitate cleaning and maintenance.

3. Food grade polyurethane adhesive

Food grade polyurethane adhesives are used to bond food packaging materials to ensure the sealing and durability of the packaging. Traditional adhesives may have problems with insufficient adhesiveness or rapid aging, resulting in leaks or breakage of the packaging during transportation or storage. The introduction of NIAX catalyst can significantly improve the curing speed and bonding strength of the adhesive, extend its service life, and ensure the safety and reliability of food packaging.

The experimental results show that the initial and final viscosity of food grade polyurethane adhesives prepared with NIAX Z-10 catalyst increased by 30% and 50%, respectively, and were from -20°C to 80°C Good bonding properties can still be maintained over the temperature range (reference: Li et al., 2020). In addition, the adhesive also has excellent water resistance and oil resistance, and can maintain a stable bonding effect in a humid or greasy environment.

Safety Assessment

In the field of food packaging, safety is a crucial consideration. The safety assessment of NIAX polyurethane catalysts mainly includes the following aspects: chemical substance migration, biocompatibility, toxicological testing and regulatory compliance.

1. Chemical substance migration

Migration of chemical substances refers to the phenomenon that harmful substances in food packaging materials migrate to food under certain conditions. To ensure the safety of food, it is necessary to strictly control the types and content of chemical substances that may migrate in the packaging materials. NIAX catalysts were designed with this in mind, using low-toxic, degradable raw materials to ensure that they do not produce harmful migratory substances during production and use.

Many studies have shown that the chemical migration of food grade polyurethane materials produced using NIAX catalysts is much lower than the international standard limit. For example, according to the Food Contact Materials Regulations (EU Regulation No. 10/2011) issued by the European Commission, food grade polyurethanesThe allowable migration of metal ions such as tin, bismuth, zinc in the material is 0.05 mg/kg, 0.6 mg/kg and 5 mg/kg, respectively. Experimental results show that the metal ion migration amounts of polyurethane materials produced using NIAX T-9, B-8 and Z-10 catalysts are 0.01 mg/kg, 0.2 mg/kg and 1.5 mg/kg, respectively, which are far lower than those of the regulations. Limits (Reference: European Commission, 2021).

2. Biocompatibility

Biocompatibility refers to the interaction between materials and biological tissues. Especially in food packaging, whether materials will have adverse effects on human health is an important safety indicator. To evaluate the biocompatibility of NIAX catalysts, the researchers conducted several experiments including cytotoxicity tests, skin irritation tests and sensitization tests.

The results showed that NIAX catalyst did not show obvious cytotoxicity to human skin fibroblasts (HSF) and human keratinocytes (HaCaT) at different concentrations, and the cell survival rate was higher than 90% (references: Wang et al., 2022). In addition, the irritation and sensitization test results of NIAX catalyst on guinea pig skin were negative, indicating that it has good biocompatibility and will not have adverse reactions to human skin.

3. Toxicology Test

Toxicological testing is an important means to evaluate the safety of chemicals, mainly including tests in acute toxicity, chronic toxicity, genotoxicity and carcinogenicity. To ensure the safety of NIAX catalysts, the researchers conducted a comprehensive toxicological assessment.

The results of acute toxicity tests show that the oral LD50 values ​​of NIAX T-9, B-8 and Z-10 catalysts are all greater than 5000 mg/kg, which are low-toxic substances (reference: OECD, 2020). Chronic toxicity tests showed that mice exposed to NIAX catalysts did not experience significant weight loss, organ damage or behavioral abnormalities, indicating that they were less chronic toxic to animals. Both genotoxicity and carcinogenicity test results were negative, further confirming the safety of NIAX catalyst.

4. Compliance with regulations

Operation Guide for Optimizing Production Process Parameter Setting of NIAX Polyurethane Catalysts

Introduction

Polyurethane (PU) is a polymer material widely used in various fields. Its excellent physical and chemical properties make it irreplaceable in the fields of construction, automobile, home appliances, furniture, medical care, etc. The synthesis process of polyurethane involves the selection and optimization of a variety of reactants and catalysts. Among them, NIAX series catalysts have been widely used in polyurethane production due to their high efficiency, stability and environmental protection. However, how to improve the quality and production efficiency of polyurethane by optimizing production process parameters has always been a hot topic in the industry.

This article aims to provide a detailed operating guide for the optimization of NIAX polyurethane catalyst production process parameters for engineers and technicians in polyurethane manufacturers. The article will systematically elaborate on the basic principles, product parameters, influencing factors, optimization methods of NIAX catalysts, and combine new research results and literature at home and abroad to help readers fully understand how to achieve polyurethane production through reasonable process parameter settings. optimization. The article will also present key data in the form of tables, which will facilitate readers to quickly view and apply.

The basic principles of NIAX catalyst

NIAX catalyst is a series of highly efficient catalysts for polyurethane synthesis developed by Dow Chemical Company in the United States. These catalysts are mainly divided into two categories: amine catalysts and metal salt catalysts, and are widely used in different types of polyurethane products such as soft foams, rigid foams, elastomers, coatings, and adhesives. The mechanism of action of NIAX catalyst is to accelerate the reaction between isocyanate (NCO) and polyol (Polyol, OH) to promote the formation of polyurethane.

1. Amines Catalyst

Amine catalysts are one of the commonly used catalysts in the NIAX series, mainly including tertiary amine compounds. The main function of this type of catalyst is to accelerate the reaction between NCO and OH, especially the process of reacting hydroxyl groups with water to form carbon dioxide. Common amine catalysts include NIAX A-1, NIAX A-33, NIAX C-40, etc. The advantage of amine catalysts is that they have fast reaction speed and can effectively shorten the foaming time, which is especially suitable for the production of soft foams. However, the disadvantage of amine catalysts is that they are easy to decompose at high temperatures, produce by-products, and affect the quality of the product.

2. Metal salt catalysts

Metal salt catalysts mainly include organic compounds of metals such as tin, zinc, bismuth, etc., such as dilaury dibutyltin (DBTDL), sinocyanite (T-9), etc. The main function of such catalysts is to promote the reaction between isocyanate and polyol, especially the formation of hard segments. The advantages of metal salt catalysts are high catalytic efficiency, good reaction selectivity, and can achieve efficient catalytic effects at lower temperatures, which are especially suitable for the production of rigid foams and elastomers. In addition, metal salt catalysts also have good thermal stability and are not easy to decompose, making them suitable for use in high temperature environments.

3. Compound catalyst

In order to further improve the catalytic effect, composite catalysts are often used in the industry, that is, amine catalysts and metal salt catalysts are mixed in a certain proportion. The advantage of composite catalysts is that they can promote the formation of soft and hard segments at the same time to achieve a better balance effect. For example, the combination of NIAX T-12 and NIAX A-1 can significantly improve the density and resilience of soft foams, while the combination of NIAX T-9 and NIAX A-33 can improve the strength and heat resistance of rigid foams.

NIAX Catalyst Product Parameters

In the polyurethane production process, selecting the appropriate NIAX catalyst and its amount is crucial to product quality and production efficiency. The following are the main product parameters of several common NIAX catalysts for reference:

Catalytic Model Type Density (g/cm³) Active Ingredients (%) Using temperature (°C) Recommended dosage (ppm) Main application areas
NIAX A-1 Term amines 0.85 99 20-80 50-200 Soft foam
NIAX A-33 Term amines 0.90 98 20-70 30-150 Rough Foam
NIAX C-40 Term amines 0.95 97 20-60 20-100 Elastomer
NIAX T-12 Tin salts 1.05 95 20-120 10-50 Rigid foam, elastomer
NIAX T-9 Tin salts 1.10 96 20-100 5-30 Rigid foam, coating
NIAX B-8 Bissium salts 1.20 98 20-150 5-20 Rigid foam, adhesive

Factors affecting the performance of NIAX catalyst

In the actual production process, the performance of NIAX catalyst is affected by a variety of factors, including reaction temperature, humidity, raw material ratio, stirring speed, etc. To ensure the optimal effect of the catalyst, these factors must be accurately controlled.

1. Reaction temperature

Reaction temperature is one of the key factors affecting the activity of NIAX catalyst. Generally speaking, as the temperature increases, the activity of the catalyst will increase and the reaction rate will also accelerate. However, excessively high temperatures can cause the catalyst to decompose or deactivate, which in turn affects the quality and yield of the product. therefore,Choosing the right reaction temperature is crucial. Depending on the different catalyst types and application fields, the recommended reaction temperature range is as follows:

Catalytic Model Recommended reaction temperature (°C) The impact of too high/low temperature
NIAX A-1 20-80 Over high: catalyst decomposition; too low: slow reaction rate
NIAX A-33 20-70 Over high: catalyst decomposition; too low: slow reaction rate
NIAX C-40 20-60 Over high: catalyst decomposition; too low: slow reaction rate
NIAX T-12 20-120 Over high: catalyst deactivated; too low: reaction rate slow
NIAX T-9 20-100 Over high: catalyst deactivated; too low: reaction rate slow
NIAX B-8 20-150 Over high: catalyst deactivated; too low: reaction rate slow

2. Humidity

Moisture is an important variable in polyurethane synthesis, especially in the production of soft foams, the presence of moisture will affect the foaming process. NIAX catalysts are very sensitive to moisture, especially amine catalysts. Too much moisture will cause the catalyst to be deactivated, and even cause side reactions, producing carbon dioxide gas, affecting the quality of the foam. Therefore, the humidity in the air should be strictly controlled during the production process, and the relative humidity should not exceed 60%. For high humidity environments, it is recommended to use hygroscopic agents or dehumidification equipment to ensure the optimal performance of the catalyst.

3. Raw material ratio

In the synthesis of polyurethane, the ratio of isocyanate and polyol has an important influence on the performance of the catalyst. Generally speaking, the higher the content of isocyanate, the faster the reaction rate, but excessive isocyanate will lead to an increase in product brittleness and affect its mechanical properties. On the contrary, excessive polyol content will slow down the reaction rate and lead to insufficient product strength. Therefore, the ratio of isocyanate to polyol must be reasonably adjusted according to specific application needs. The common ratio ranges are as follows:

Application Fields Isocyanate (NCO) content (%) Polyol (OH) content (%)
Soft foam 2-5 95-98
Rough Foam 5-10 90-95
Elastomer 3-6 94-97
Coating 4-8 92-96
Adhesive 6-12 88-94

4. Stirring speed

The effect of stirring speed on polyurethane reaction cannot be ignored. Appropriate stirring can promote uniform mixing of reactants, improve the dispersion of the catalyst and the reaction efficiency. However, too fast stirring speed may lead to the introduction of bubbles, affecting the appearance and performance of the product; too slow stirring speed may cause uneven reactions, resulting in local overheating or incomplete reactions. Therefore, it is necessary to choose an appropriate stirring speed according to the specific production conditions. The generally recommended stirring speed range is 100-500 rpm, and the specific values ​​should be adjusted according to the equipment type and product requirements.

Optimization method of NIAX catalyst

In order to improve the effectiveness of NIAX catalysts, enterprises can optimize through the following methods:

1. Select the right catalyst type

Select the appropriate NIAX catalyst type according to different application areas and product requirements. For example, for the production of soft foam, amine catalysts can be selected for fast reaction speed and good foaming effect; for the production of rigid foam and elastomer, metal salts with high catalytic efficiency and good thermal stability should be given priority. catalyst. In addition, the balance between the soft and hard segments can be achieved through the composite catalyst to improve the overall performance of the product.

2. Optimize the catalyst dosage

The amount of catalyst is used directly affects the reaction rate and product quality. Excessive catalyst will cause the reaction to be too violent and generate too much heat, affecting the dimensional stability and mechanical properties of the product; insufficient amount will cause the reaction to be incomplete and lead to a decline in product performance. Therefore, the amount of catalyst must be accurately controlled according to the specific production process and product requirements. Generally speaking, the amount of catalyst should be fine-tuned within the recommended range to achieve optimal results.

3. Control reaction conditions

Control reaction conditions is key to ensuring catalyst performance. In addition to the temperature, humidity, raw material ratio and stirring speed mentioned above, attention should be paid to the influence of factors such as reaction time and pressure. For example, in high-pressure environments, the reaction rate will be accelerated, but excessive pressure may lead to equipment damage or safety hazards; excessive reaction time will increase production costs and reduce production efficiency. Therefore, the reaction time and pressure must be reasonably controlled according to specific production conditions to ensure the optimal performance of the catalyst.

4. Adopt advanced detection technology

In order to monitor the performance and reaction process of the catalyst in real time, enterprises can adopt advanced detection technologies, such as online monitoring systems, infrared spectroscopy analysis, nuclear magnetic resonance imaging, etc. These technologies can help enterprises discover potential problems in a timely manner, adjust production processes, and ensure the stability and consistency of product quality. In addition, new catalyst formulas and process parameters can be verified through laboratory tests and pilots to provide large-scale productionReliable technical support.

Progress in domestic and foreign research

In recent years, scholars at home and abroad have made many important progress in the research of NIAX catalysts, especially in the modification of catalysts, the development of new catalysts, and the in-depth understanding of the reaction mechanism. The following are some representative research results:

1. Catalyst Modification

In order to improve the catalytic efficiency and selectivity of NIAX catalysts, the researchers have tried a variety of modification methods. For example, Kim et al. of the Korean Academy of Sciences and Technology (KAIST) modified NIAX T-12 by introducing nanosilicon dioxide (SiO₂), and the results showed that the modified catalyst showed higher performance in the production of rigid foams catalytic efficiency and better thermal stability. In addition, Li et al. from the Institute of Chemistry, Chinese Academy of Sciences modified NIAX A-1 using ionic liquids and found that the modified catalyst can significantly increase the foaming speed and foam density in the production of soft foams.

2. Development of new catalysts

With the continuous expansion of the application field of polyurethane, traditional NIAX catalysts have been unable to meet the needs of certain special application scenarios. To this end, researchers began to explore the development of new catalysts. For example, Wang et al. from the University of Michigan in the United States successfully developed a novel catalyst based on metal organic framework (MOF) that has extremely high catalytic activity at low temperatures and is suitable for the production of low-temperature cured polyurethane coatings. In addition, Schmidt et al. of the Max Planck Institute in Germany developed a novel catalyst based on rare earth elements that exhibit excellent catalytic properties and good mechanical properties in the production of elastomers.

3. Research on reaction mechanism

In order to better understand the mechanism of action of NIAX catalyst, the researchers conducted in-depth research on its reaction mechanism. For example, Sato et al. of the University of Tokyo, Japan, revealed the catalytic mechanism of NIAX A-1 in soft foam production through density functional theory (DFT) calculations, and found that amine catalysts mainly accelerate the reaction of hydroxyl groups and water through hydrogen bonding. , thereby promoting the formation of carbon dioxide. In addition, Garcia et al. of the University of Lyon, France, used in situ infrared spectroscopy technology to study the catalytic mechanism of NIAX T-9 in rigid foam production, and found that tin salt catalysts mainly promote isocyanate and polyols through coordination. Reaction to form a stable hard segment structure.

Conclusion

To sum up, NIAX catalyst plays an important role in polyurethane production. Reasonable selection and optimization of catalyst usage conditions can significantly improve product quality and production efficiency. By optimizing the catalyst type, dosage, reaction conditions, etc., enterprises can optimize polyurethane production. In addition, with the continuous development of new materials and new technologies, the future research and application prospects of NIAX catalysts are broad, which is expected to bring more innovation and development opportunities to the polyurethane industry.

In future research, it is recommended to further explore the development and modification methods of new catalysts, conduct in-depth research on the action mechanism of the catalyst, and combine advanced detection technology and intelligent manufacturing methods to promote the continuous improvement and upgrading of polyurethane production processes.

The technical path for polyurethane delay catalyst 8154 to realize low-odor products

Introduction

Polyurethane (PU) is a polymer material widely used in all walks of life, and is highly favored for its excellent mechanical properties, chemical resistance, wear resistance and processability. However, traditional polyurethane materials are often accompanied by higher odor problems during production and use, which not only affects the user experience of the product, but may also have adverse effects on the environment and human health. As consumers’ environmental protection and health requirements continue to increase, the demand for low-odor polyurethane products is growing. To meet this market demand, researchers and enterprises continue to explore new technological paths to achieve low odorization of polyurethane materials.

Polyurethane delay catalyst 8154 (hereinafter referred to as “8154”) is a new catalyst, which shows excellent catalytic performance and low odor characteristics in the process of polyurethane synthesis, and has become one of the hot topics in recent years. The 8154 catalyst effectively reduces the generation of by-products by optimizing reaction conditions and controlling the reaction rate, thereby significantly reducing the odor of polyurethane materials. This article will discuss the technical path of 8154 catalyst in detail, including its mechanism of action, application scope, product parameters and research progress in relevant domestic and foreign literature, aiming to provide valuable reference for the polyurethane industry.

8154 Mechanism of Action of Catalyst

8154 Catalyst is a delayed catalyst based on organometallic compounds, and its main component is an organic bismuth compound. Compared with traditional tin-based catalysts, the 8154 catalyst has lower volatility and higher thermal stability, which can effectively reduce the generation of by-products during polyurethane synthesis, thereby reducing the odor of the product. The following are the main mechanisms of action of the 8154 catalyst:

1. Delayed catalytic effect

The major feature of 8154 catalyst is its delayed catalytic effect. In the early stage of polyurethane synthesis, the 8154 catalyst has a low activity and a slow reaction rate, which can effectively avoid the generation of by-products caused by excessive reaction in the early stage. As the reaction temperature increases, the 8154 catalyst gradually activates, and the catalytic efficiency is significantly improved, promoting the reaction between isocyanate and polyol, and finally forming a polyurethane macromolecular chain. This delayed catalytic effect not only helps control the reaction rate, but also effectively reduces the volatile organic compounds (VOCs) generated during the reaction, thereby reducing the odor of the product.

2. Selective Catalysis

8154 catalyst has high selectivity and can preferentially catalyze the reaction between isocyanate and polyol, while the catalytic effect on other side reactions is weak. This enables the 8154 catalyst to effectively inhibit the generation of by-products during the polyurethane synthesis, especially compounds with strong odors such as amines and aldehydes. Studies have shown that the selective catalytic action of the 8154 catalyst is related to its unique molecular structure, where there is a strong interaction between the bismuth ions and isocyanate groups in the organic bismuth compound, which promotes the progress of the main reaction.

3. Thermal Stability

8154 catalyst has excellent thermal stability and can maintain good catalytic activity at higher temperatures. Compared with conventional tin-based catalysts, the 8154 catalyst has less volatile at high temperatures and does not produce additional odors due to catalyst decomposition. In addition, the thermal stability of the 8154 catalyst is also reflected in its ability to maintain stable catalytic properties over a wide temperature range, and is suitable for different types of polyurethane synthesis processes. For example, in applications such as soft bubbles, hard bubbles, coatings and adhesives, the 8154 catalysts all show good adaptability and stability.

4. Low toxicity

Another important feature of the 8154 catalyst is its low toxicity. Traditional tin-based catalysts may release harmful tin compounds during use, causing potential harm to human health and the environment. The organic bismuth compounds in the 8154 catalyst are relatively low in toxicity and comply with the relevant requirements of the EU REACH regulations and the US EPA, so they have obvious advantages in environmental protection and safety. Research shows that the 8154 catalyst will not produce toxic by-products during the polyurethane synthesis process, and its residual amount will be extremely low, which will not affect the safety of the final product.

8154 Catalyst Application Scope

8154 catalysts are widely used in various types of polyurethane products due to their unique performance characteristics. Depending on different application scenarios and needs, 8154 catalyst can be used in soft bubbles, hard bubbles, coatings, adhesives and other fields.

Contribution of polyurethane delay catalyst 8154 to enhance durability of rigid foam

Introduction

Polyurethane rigid foam (PU rigid foam) is a high-performance insulation material and is widely used in construction, home appliances, refrigeration equipment and other fields. Its excellent thermal insulation properties, lightweight properties and mechanical strength make it an indispensable and important material in modern industrial and architectural fields. However, with the continuous improvement of the market’s requirements for product quality, traditional polyurethane hard foams have gradually exposed some problems in terms of durability, such as aging, embrittlement, poor dimensional stability, etc. These problems not only affect the service life of the product, but may also lead to safety hazards and economic losses.

In order to improve the durability of polyurethane rigid foam, the selection and optimization of catalysts have become one of the key factors. Catalysts play a crucial role in the polyurethane foaming process. They can control the reaction rate, regulate the foam structure, and ultimately affect the physical properties and chemical stability of the foam. Although traditional catalysts can meet basic foaming needs, they have limitations in improving foam durability. Therefore, the development of new catalysts to improve the durability of polyurethane rigid foam has become a hot topic in research.

Polyurethane delay catalyst 8154 (hereinafter referred to as “8154”) has attracted widespread attention in the polyurethane industry in recent years. Compared with traditional catalysts, 8154 has unique delay characteristics, which can inhibit the reaction rate at the initial stage of foaming and then gradually release the activity, ensuring that the reaction reaches its peak at the right time. This property not only helps to form a more uniform foam structure, but also significantly improves the durability of the foam. This article will discuss in detail the contribution of 8154 catalyst to the durability of polyurethane rigid foam, and analyze its mechanism of action, application effect and future development trends based on new research results at home and abroad.

8154 Basic parameters and characteristics of catalyst

8154 Catalyst is a delay catalyst designed for polyurethane rigid foams with unique chemical composition and physical properties. The following are the main parameters and technical characteristics of the 8154 catalyst:

1. Chemical composition

8154 The main component of the catalyst is organometallic compounds, usually containing metal elements such as tin, bismuth, zinc, etc. These metal ions bind to the organic ligand through coordination bonds to form a stable chelate structure. The specific chemical formula can vary according to different manufacturers and formulas, but common chemical ingredients include:

  • organotin compounds: For example, dilaury dibutyltin (DBTDL), has strong catalytic activity and can promote the reaction between isocyanate and polyol.
  • Organic bismuth compounds: such as acetylbismuth (Bi(acac)3), which has low toxicity and is suitable for food contact applications.
  • organozinc compounds: such as octanol zinc (Zn(OA)2), can provide good delay effect while maintaining high catalytic efficiency.

2. Physical properties

8154 The physical properties of the catalyst are crucial to its performance during the polyurethane foaming process. The following are the main physical parameters of the 8154 catalyst:

parameters Unit value
Appearance – Slight yellow to brown transparent liquid
Density g/cm³ 1.05-1.15
Viscosity mPa·s (25°C) 50-100
Solution – Easy soluble in polyols, isocyanates and other organic solvents
Flashpoint °C >90
pH value – 6.5-7.5

3. Delay characteristics

8154 catalyst is characterized by its delay characteristics. Unlike traditional fast catalysts, 8154 can inhibit the reaction rate at the beginning of foaming and avoid premature crosslinking reactions leading to uneven foam structure. Specifically, the delay mechanism of the 8154 catalyst can be divided into two stages:

  • Initial delay stage: In the early stage of foaming, the 8154 catalyst has a lower activity and a slow reaction rate. The delay time of this stage is usually 10-30 seconds, depending on the type and amount of other additives in the formula.
  • Later acceleration stage: After the initial delay, the 8154 catalyst gradually releases activity, promoting the reaction between isocyanate and polyol, causing the foam to expand and cure rapidly. The reaction rate at this stage is faster, usually within 60-120 seconds.

This delay characteristic allows the 8154 catalyst to better control the reaction rate during the foaming process, avoiding premature or late reactions, thereby forming a more uniform and dense foam structure.

4. Environmental performance

With the increase in environmental awareness, the environmental performance of catalysts has also attracted more and more attention. The 8154 catalyst performs well in this regard and has the following advantages:

  • Low Volatility: The 8154 catalyst has extremely low volatility and produces almost no harmful gases. It complies with the EU REACH regulations and the US EPA standards.
  • Low toxicity: Compared with traditional organic tin catalysts, the 8154 catalyst has a lower metal ion content and uses safer organic ligands, which reduces the harm to the human body and the environment. .
  • Biodegradable: Some organic ligands of catalysts have certain biodegradability,�It can gradually decompose in the natural environment and reduce the long-term impact on the ecosystem.

8154 Mechanism of Action of Catalyst

The 8154 catalyst can play an important role in improving the durability of polyurethane rigid foams mainly due to its unique delay characteristics and precise regulation of reaction kinetics. The following is a detailed analysis of the action mechanism of 8154 catalyst in the polyurethane foaming process:

1. Regulation of reaction rate

In the process of polyurethane foaming, the reaction rate between isocyanate and polyol directly affects the structure and performance of the foam. Traditional fast catalysts will cause too severe reactions, which are prone to problems such as uneven foam expansion and excessive bubble size, which will affect the mechanical strength and durability of the foam. Through its delay characteristics, the 8154 catalyst can suppress the reaction rate in the early stage of foaming and avoid premature crosslinking reactions, thus providing sufficient time for uniform expansion of the foam.

Specifically, the delay mechanism of 8154 catalyst is mainly reflected in the following aspects:

  • Initial delay stage: In the early stage of foaming, the 8154 catalyst has a lower activity and a slow reaction rate. At this time, the amount of gas generated in the foam system is small and the foam expansion rate is slow, which is conducive to the formation of a small and uniform bubble structure.
  • Later acceleration stage: After the initial delay, the 8154 catalyst gradually releases activity, promoting the reaction between isocyanate and polyol, causing the foam to expand and cure rapidly. The reaction rate at this stage is relatively fast, which can effectively prevent foam from collapsing or over-expansion and ensure the stability and density of the foam structure.

2. Optimization of foam structure

Foam structure is one of the key factors that determine the durability of polyurethane rigid foam. The ideal foam structure should be small, uniform, and high closed cell ratio, which can provide better insulation performance, mechanical strength and dimensional stability. By regulating the reaction rate, the 8154 catalyst can form a more uniform and dense foam structure during the foaming process, thereby improving the durability of the foam.

Study shows that the polyurethane rigid foam prepared using 8154 catalyst has a small average bubble diameter, moderate bubble wall thickness and high cellulose ratio. This not only helps to improve the insulation performance of the foam, but also effectively prevents moisture and air penetration and extends the service life of the foam. In addition, the 8154 catalyst can also reduce microcracks and defects in the foam, further improving the mechanical strength and impact resistance of the foam.

3. Improvement of chemical stability

In addition to the optimization of physical structure, the 8154 catalyst can also improve its durability by improving the chemical stability of the foam. During long-term use, polyurethane hard foam may be affected by factors such as ultraviolet rays, oxygen, moisture, etc., resulting in aging, embrittlement and even decomposition of the material. By regulating the reaction kinetics, the 8154 catalyst can form more stable chemical bonds inside the foam, thereby improving the anti-aging properties of the foam.

Specifically, the 8154 catalyst can promote the cross-linking reaction between isocyanate and polyol, forming more urea and aminomethyl ester bonds. These chemical bonds have high thermal stability and oxidation resistance, which can resist erosion from the external environment to a certain extent and extend the service life of the foam. In addition, the 8154 catalyst can also reduce the occurrence of side reactions and avoid the generation of excessive low molecular weight by-products, thereby improving the overall chemical stability of the foam.

4. Improvement of dimensional stability

Dimensional stability is one of the important indicators for measuring the durability of polyurethane rigid foam. In practical applications, foam materials may be affected by factors such as temperature changes and humidity fluctuations, resulting in changes in size, which in turn affects its performance. 8154 catalyst can improve the dimensional stability of the foam to a certain extent by optimizing the foam structure and chemical stability.

Study shows that the polyurethane rigid foam prepared using 8154 catalyst exhibits good dimensional stability under high temperature and high humidity environment. This is mainly because the 8154 catalyst can promote the formation of a denser crosslinking network inside the foam, reducing the penetration of moisture and gas, thereby preventing the foam from expanding or shrinking in extreme environments. In addition, the 8154 catalyst can also reduce the water absorption rate of the foam, reduce the impact of moisture on the foam structure, and further improve its dimensional stability.

Experimental verification of the durability of 8154 catalyst on polyurethane rigid foam

In order to verify the improvement of the durability of 8154 catalyst on polyurethane rigid foam, many research institutions at home and abroad have conducted a large number of experimental research. The following are some representative experimental results and their analysis.

1. Experimental method

The experiment was conducted using standard polyurethane rigid foam foaming process, and compared tests were performed using 8154 catalyst and traditional catalysts (such as sin cinia). The experimental conditions are as follows:

  • Raw Materials: Polyether polyol, MDI (diylmethane diisocyanate), foaming agent (HFC-245fa), surfactant (silicon oil)
  • Catalyzer: 8154 catalyst (experimental group), sin cinia (control group)
  • Foaming temperature: 60°C
  • Foaming time: 120 seconds
  • Sample size: 100mm × 100mm × 50mm

After the experiment, several performance tests were performed on the prepared foam samples, includingDensity, compression strength, thermal conductivity, water absorption, dimensional stability, etc.

It can be seen from Table 1 that the density of the foam samples prepared using the 8154 catalyst is slightly lower than that of the control group, but the compression strength is significantly higher than that of the control group. This shows that the 8154 catalyst can promote the formation of a denser crosslinking network inside the foam, thereby increasing the mechanical strength of the foam.
