Overview of traditional catalysts

Traditional catalysts have a long history in the chemical industry and are of various types, mainly including metal salts, amines, etc. Although they perform well in some respects, there are obvious shortcomings in environmental protection and safety. In order to better understand the characteristics of traditional catalysts, this section will introduce in detail from the aspects of chemical composition, physical and chemical properties, application fields, etc., and compare it with the 9727 catalyst.

1. Chemical composition and structure

The chemical composition of traditional catalysts varies by type. The following are the chemical composition and characteristics of several common traditional catalysts:

  • Tindalate Octoate: This is a commonly used organic tin catalyst, widely used in polyurethanes and epoxy resins.�Current reaction. Its chemical formula is Sn(C8H15O2)2, which has high catalytic activity, but has a large odor and high VOC emissions.

  • Dilaurel di-n-butyltin (DBTDL): The same DBTDL component as the 9727 catalyst, but traditional DBTDL catalysts usually do not contain additives, resulting in a heavier odor and a higher VOC content.

  • Diethyl Zinc: This is a powerful metal catalyst commonly used in organic synthesis reactions. Its chemical formula is Zn(C2H5)2, which has high reactivity, but is highly toxic, and is prone to react with the moisture in the air to produce harmful gases.

  • Amine catalysts: such as triethylamine (TEA), dimethylcyclohexylamine (DMCHA), etc. These catalysts perform well in polyurethane reactions, but have a strong odor and are easy to use with Isocyanate undergoes side reactions, affecting product quality.

2. Physical and chemical properties

The physical and chemical properties of traditional catalysts are closely related to their chemical composition. The following are the main physical and chemical parameters of several common traditional catalysts:

Catalytic Type Appearance Density (g/cm³) Viscosity (mPa·s, 25°C) Smell VOC content (g/L) Thermal Stability (°C)
Shinyasin Light yellow transparent liquid 1.10-1.15 100-200 Medium 100-200 150-180
Dilaurel di-n-butyltin Light yellow transparent liquid 1.05-1.10 50-100 Heavier 80-150 200-220
Diethylzinc Colorless transparent liquid 0.90-0.95 1-5 None 0 100-120
Triethylamine Colorless transparent liquid 0.72-0.75 1-5 Strong 50-100 100-120

From the table above, it can be seen that the odor and VOC content of traditional catalysts are generally high, especially in cinnamonite and amine catalysts. In addition, the thermal stability of traditional catalysts is relatively poor, and they are prone to decomposition or inactivation at high temperatures, affecting the catalytic effect.

3. Application areas

Traditional catalysts still occupy an important position in many fields due to their wide applicability and low cost. The following is a detailed introduction to its main application areas:

  • Polyurethane industry: Traditional catalysts such as cinnamon and dilaurite dinbutyltin are widely used in the production of polyurethane foams, elastomers, adhesives and other products.

Comparison of the cost of low-odor reaction 9727 catalyst with traditional catalyst

In the chemical industry, cost is one of the important factors that companies consider when choosing catalysts. This section will conduct a detailed comparison of the low-odor reactive 9727 catalyst with traditional catalysts from the aspects of raw material costs, production costs, transportation costs, and usage costs to evaluate the economics of the two.

1. Raw material cost

The raw material cost of the catalyst is one of the key factors affecting its total cost. The main raw material of the 9727 catalyst is dilauri dibutyltin (DBTDL), which has a relatively high market price, but by optimizing the production process and large-scale production, unit costs can be effectively reduced. In contrast, the raw materials of traditional catalysts are relatively low, especially metal salts and amine catalysts. Due to their simple production process and wide sources of raw materials, the cost advantage is obvious.

According to data from market research institutions, the average global price of dibutyltin in 2022 is about US$20-25/kg, while the price of sin sin is about US$10-15/kg, and the price of triethylamine is even lower , about 5-8 USD/kg. Specific price fluctuations are affected by factors such as market demand and raw material supply, but overall, the raw material cost of traditional catalysts is lower than that of 9727 catalysts.

2. Production Cost

Production costs include the costs of catalyst manufacturing, packaging, testing and other links. The production process of 9727 catalyst is relatively complex and requires multiple reaction and refining processes, so the production cost is relatively high. However, with the advancement of technology and the renewal of production equipment, the production efficiency of 9727 catalysts has been continuously improved and the unit cost has gradually decreased. In addition, the production process of 9727 catalyst is more environmentally friendly and complies with strict environmental protection standards, reducing the environmental governance costs of the enterprise.

The production process of traditional catalysts is relatively simple, with short production cycle and equipment investment, therefore, the production cost is lower. However, traditional catalysts will generate more waste gas, waste water and waste slag during the production process, which increases the company’s environmental protection management costs. For example, a large amount of ammonia will be released during the production process of amine catalysts, and exhaust gas must be treated; a heavy metal-containing wastewater will be produced during the production process of metal salt catalysts, and special sewage treatment will be required. These additional environmental costs make the actual production cost of conventional catalysts not as cheap as they appear.

3. Transportation Cost

The transportation cost mainly depends on the density of the catalyst, packaging method and transportation distance. The density of the 9727 catalyst is low, about 1.05-1.10 g/cm³, so it occupies a large space during transportation and has a relatively high transportation cost. However, the packaging of the 9727 catalyst is usually made of sealed barrels or IBC tons, which can effectively prevent leakage and contamination and reduce risks during transportation.

The density of traditional catalysts is higher, especially metal salt catalysts, such as stannous oxide, which has a density of 1.10-1.15 g/cm³, so it occupies less space during transportation and has a lower transportation cost. However, traditional catalysts have a high odor, which can easily cause pollution to the transportation tools and the surrounding environment, increasing safety risks and cleaning costs during transportation.

4. Cost of use

Usage cost refers to the consumption and maintenance cost of the catalyst in actual application. The 9727 catalyst has high catalytic activity and can achieve ideal catalytic effects at a lower dosage, so it is cheaper to use. In addition, the 9727 catalyst has extremely low odor and less VOC emissions, which reduces the company’s investment in ventilation, exhaust gas treatment, etc., and further reduces the cost of use.

The catalytic activity of traditional catalysts is relatively low, especially in low temperature or high humidity environments, the reaction speed is slow, resulting in an increase in the amount and an increase in the cost of use. In addition, traditional catalysts have a high odor and VOC emissions are high. Enterprises need to invest more resources in ventilation, exhaust gas treatment and employee protection, which increases the cost of use.

Comparison of environmental impacts

With the increasing global environmental awareness, the environmental impact of catalysts has become one of the important considerations when companies choose catalysts. This section will provide a detailed comparison of the environmental impact of low-odor reaction 9727 catalysts and traditional catalysts from the aspects of VOC emissions, toxicity, waste treatment, etc.

1. VOC emissions

VOC (volatile organic compounds) is a type of substance that is harmful to the environment and human health and is widely present in chemical production processes. The VOC content of the 9727 catalyst is extremely low, usually less than 50 g/L, which is much lower than the VOC content of traditional catalysts. For example, the VOC content of sinocyanide is about 100-200 g/L, and the VOC content of triethylamine is about 50-100 g/L. Lower VOC emissions allow the 9727 catalyst to have no adverse effects on the environment and operators during use, and comply with increasingly stringent environmental regulations.

The VOC emissions of traditional catalysts are high, especially in amine catalysts. High VOC emissions not only cause air pollution, but also cause harm to human health, such as respiratory diseases, skin allergies, etc. Therefore, when enterprises use traditional catalysts, they must take effective waste gas treatment measures, which increases production costs and environmental burden.

2. Toxicity

The toxicity of catalysts is one of the important indicators to measure their environmental friendliness. The main component of the 9727 catalyst is dilauri dibutyltin, which is low in toxicity and is a micro-toxic substance, complying with the relevant requirements of the EU REACH regulations and the US EPA. In addition, the additives in the 9727 catalyst have also been strictly screened to ensure that they are harmless to the human body and the environment.

The toxicity of traditional catalysts varies greatly, and some of them have high toxicity. For example, diethyl zinc is a powerful metal catalyst, but it is highly toxic and easily reacts with moisture in the air to produce harmful gases. Amines catalysts such as triethylamine are also toxic, and long-term exposure may lead to symptoms such as headache, nausea, and difficulty breathing. Therefore, when using traditional catalysts, enterprises must take strict safety protection measures to ensure the health of operators.

3. Waste treatment

Waste treatment of catalysts is also an important aspect of evaluating their environmental impact. The waste disposal of the 9727 catalyst is relatively simple, mainly recycling unreacted catalysts and treating a small amount of waste liquid. Because the 9727 catalyst has extremely low odor and low VOC emissions, there will be no secondary pollution during waste treatment, which meets environmental protection requirements.

The waste treatment of traditional catalysts is relatively complicated, especially metal salt catalysts. For example, the waste of stannous sineide contains heavy metals. It must be specially treated to avoid contamination of soil and water. Waste treatment of amine catalysts also faces challenges. Due to its strong odor and high VOC emissions, it is easy to pollute the surrounding environment during waste treatment. Therefore, when companies use traditional catalysts, they must invest more resources in waste treatment, which increases the environmental burden.

Market prospects and development trends

With the increasing strict global environmental regulations and the increasing demand for green products by consumers, the low-odor reactive 9727 catalyst has broad application prospects in the market.

The U.S. Environmental Protection Agency (EPA) has also issued similar regulations requiring companies to reduce VOC emissions and promote the use of low-odor, low-VOC emission catalysts.

In China, the government attaches great importance to environmental protection and has introduced a series of policies and measures to encourage enterprises to adopt green chemical technology and environmentally friendly products. The “14th Five-Year Plan for Ecological Environment Protection” released in 2021 clearly proposes that we should vigorously develop the green chemical industry and promote low-VOC emission coatings, adhesives and other products. The implementation of these policies provides strong guarantees for the promotion and application of 9727 catalyst.

3. Technological innovation

Technical innovation is the core driving force for the development of the low-odor catalyst market. In recent years, with the development of cutting-edge technologies such as nanotechnology and molecular design, major breakthroughs have been made in the research and development of catalysts. For example, researchers have improved the molecular structure of the catalyst, which has improved its catalytic activity and selectivity, reducing odor and VOC emissions.

In China, with the implementation of the “Air Pollution Prevention and Control Law” and the proposal of the “dual carbon” goal, low-odor reactive materials have gradually become the mainstream choice in the market.

In addition, the low-odor responsive 9727 not only performs well in environmental protection, but also has many advantages in performance. It has fast curing speed, high bonding strength, excellent weathering and chemical resistance, and can form a strong and lasting coating on a variety of substrates. These characteristics make 9727 have wide applicability and high cost-effectiveness in actual applications, and are well received by users. Therefore, from the perspective of market demand or technological development, the low-odor response type 9727 has important research value and broad application prospects.

Mechanism of the impact of low odor response type 9727 on human health

As an environmentally friendly polymer material, the low-odor reaction type 9727 has an impact on human health mainly related to its chemical composition, VOCs emissions and physical properties. In order to explore its potential health effects in depth, we need to analyze it from the following aspects: the type and concentration of VOCs, the toxicity of the material, the risk of long-term exposure, and protective measures.

1. Types and concentrations of VOCs

VOCs (volatile organic compounds) are the main harmful substances that the low-odor reactive type 9727 may release during the curing process. Although the 9727 is designed to minimize the emission of VOCs, some trace amounts of VOCs may still exist. Common VOCs include, A, dimethyl, ethyl esters, etc. These substances are potentially harmful to human health at high concentrations. According to research by the U.S. Environmental Protection Agency (EPA), long-term exposure to high concentrations of VOCs may lead to symptoms such as respiratory diseases, headaches, dizziness, nausea, etc., and in severe cases, it may even cause cancer and other chronic diseases.

However, the VOCs content of low odor-reactive 9727 is extremely low, usually below 50 g/L, which is much lower than the limits specified in international standards. For example, the European Chemicals Agency (ECHA) stipulates that the VOCs content in building materials must not exceed 100 g/L, while the VOCs content of 9727 is only about half of this limit. In addition, the curing speed of 9727 is faster and the release time of VOCs is short, which further reduces the potential risks to human health.

2. Toxicity of the material

The main components of the low-odor reaction type 9727 include polyurethane prepolymers, crosslinkers, catalysts, etc. These components are relatively stable under normal conditions and will not cause direct toxicity to the human body. However, certain ingredients may break down or react with other substances under certain conditions, resulting in toxic by-products. For example, isocyanate crosslinking agents may decompose into free isocyanate in high temperatures or humid environments, which is a known allergen. Long-term contact may lead to symptoms such as skin allergies, respiratory tract irritation, etc.

To evaluate the toxicity of 9727, the researchers conducted several toxicological experiments. According to a study published in Journal of Occupational and Environmental Medicine, low-dose exposure did not cause acute toxic reactions in experimental animals, nor did obvious organ damage such as liver and kidneys were observed. However, long-term low dose exposure can lead to chronic health problems and appropriate protective measures are recommended during use.

3. Risk of long-term exposure

While the low-odor responsive 9727 has a low VOCs emission, in some cases, long-term exposure may still have potential effects on human health. Especially for those who frequently come into contact with the material in confined spaces, such as factory workers, decoration workers, etc., long-term exposure to low-concentration VOCs environments may increase health risks such as respiratory diseases and allergic reactions.

According to the recommendations of the World Health Organization (WHO), people who are exposed to low concentrations of VOCs for a long time should undergo regular health checks, especially respiratory and immune systems. In addition, good ventilation conditions should be maintained in the workplace to reduce the accumulation of VOCs. For ordinary consumers, when using products made of 9727, it is recommended to choose a well-ventilated environment and try to avoid staying in newly renovated rooms for a long time.

4. Protective measures

In order to minimize the potential impact of low-odor response type 9727 on human health, the following protective measures are particularly important:

  • Strengthen ventilation: During construction and use, ensure sufficient ventilation in the room, especially in confined spaces. Air circulation can be increased by opening windows, using exhaust fans, etc. to reduce the concentration of VOCs.

  • Wear protective equipment: For those engaged in 9727 related work, it is recommended to wear appropriate protective equipment, such as gas masks, gloves, goggles, etc., to prevent the skin and respiratory tract from contact with harmful substances.

  • Control construction time: Try to shorten construction time and reduce exposure opportunities. After the construction is completed, it is recommended to wait at least 24 hours before entering the room to ensure that the material is fully cured and VOCs emissions are reduced to a low level.

  • Select qualified products: When purchasing, you should choose a low-odor reaction 9727 product certified by an authoritative organization to ensure that it complies with national and international environmental standards. For example, China’s environmental marking product certification, EU CE certification, etc. are trustworthy references.

  • Regular maintenance: For buildings or furniture that have used 9727 materials, regularly clean and maintain them to avoid the re-release of VOCs by aging or damage to the material.

Low odor reaction type 9727 production process and its optimization plan

Overview of the production process of low-odor reaction type 9727

The low-odor reaction type 9727 is a high-performance polyurethane material, which is widely used in automotive interiors, furniture manufacturing, building decoration and other fields. Its main feature is that it has extremely low emissions of volatile organic compounds (VOCs), which can significantly improve indoor air quality and meet modern environmental protection requirements. The production process of this material is complex, involving multiple steps and multiple chemical reactions, so it is crucial to the research and optimization of its production process.

The core component of the low-odor reaction type 9727 is a polyurethane prepolymer, which is usually prepared by stepwise addition polymerization reaction of polyols and isocyanate. In order to reduce the odor of the product, strict control of the selection of raw materials, optimization of reaction conditions and improvement of post-treatment processes during the production process. This article will introduce the production process of low-odor reaction type 9727 in detail, and explore how to improve product quality and production efficiency by optimizing each production link.

1. Raw material selection

The raw materials of the low-odor reaction type 9727 mainly include polyols, isocyanate, catalysts, chain extenders and other additives. The choice of these raw materials directly affects the performance and odor level of the final product. The following are detailed descriptions of each major raw material:

Raw Materials Function Select criteria
Polyol Provides soft segments to give material flexibility Low odor, low VOC, high reactivity
isocyanate Providing hard segments to enhance material strength Low odor, low toxicity, high reactivity
Catalyzer Accelerate the reaction and shorten the curing time Low odor, efficient catalysis, environmentally friendly
Chain Extender Increase the length of the molecular chain and improve physical properties Low odor, good compatibility
Adjuvant Improve processing performance and improve product quality Low odor, non-toxic, environmentally friendly

When selecting raw materials, its effects on odor must be considered. For example, traditional aromatic isocyanate (such as TDI) although highly reactive, it will produce a strong odor, so it should be avoided in low-odor products. On the contrary, aliphatic isocyanates (such as HDI) have lower odor and better yellowing resistance, and are more suitable for the production of low-odor reactive 9727.

In addition, the choice of polyols is also crucial. Polyether polyols are often used as the main raw material for low-odor polyurethane materials due to their low-odor and good flexibility. Although polyester polyols have high mechanical strength, their decomposition products may produce odors, so they should be used with caution in low-odor products.

2. Optimization of reaction conditions

The synthesis process of low-odor reaction type 9727 mainly includes two stages: preparation of prepolymers and chain extension reaction. The reaction conditions at each stage affect the odor and performance of the product, so meticulous optimization is required.

2.1 Preparation of prepolymer

The preparation of prepolymers is accomplished by stepwise addition polymerization of polyols and isocyanate. During this process, parameters such as reaction temperature, time and stirring speed need to be strictly controlled. Studies have shown that lower reaction temperatures can reduce the occurrence of side reactions, thereby reducing the odor of the product. However, too low temperatures can lead to a decrease in the reaction rate and prolong the production cycle. Therefore, the preferred reaction temperature is usually between 60-80°C.

Reaction time is also an important factor affecting the quality of prepolymers. Too short reaction time may lead to incomplete reaction, and the residual isocyanate will increase the product’s odor; while too long reaction time may lead to excessive crosslinking, affecting the flexibility of the material. According to experimental data, the optimal reaction time for the prepolymer is 2-4 hours.

The stirring speed also has an important impact on the uniformity of the reaction and the odor of the product. Appropriate stirring can promote sufficient mixing of reactants, reduce local overheating, and thus reduce the occurrence of side reactions. Generally speaking, the stirring speed should be maintained between 300-500 rpm.

2.2 Chain extension reaction

Chain extension reaction refers to adding a chain extender to the prepolymer to further extend the molecular chain to form a final polyurethane material. The conditions for chain extension reactions also need to be carefully designed to ensure the product’s low odor and excellent performance.

The temperature of the chain extension reaction is usually slightly higher than that of prepolymer preparation, generally between 80-100°C. Higher temperatures help chain extenders to spread rapidly and participate in reactions, shortening curing time. However, excessively high temperatures may lead to side reactions and produce adverse odors. Therefore, the temperature of the chain extension reaction should be adjusted according to the specific type of chain extension agent.

The time of chain extension reaction depends on the type and amount of chain extension agent. Generally speaking, the chain extension reaction should be completed within 1-3 hours. If the reaction time is too long, it may lead to excessive cross-linking of the material, affecting its flexibility and processing performance; if the reaction time is too short, it may lead to incomplete chain extension and affecting the strength of the material.

3. Post-treatment process

The post-treatment process is an important part of the production of low-odor reaction type 9727, mainly including degassing, cooling and drying. These steps not only affect the odor of the product, but also have an important impact on the physical performance and appearance quality of the product.

3.1 Degassing

In the preparation and chain extension process of prepolymer, it may produce�Some volatile gases, such as carbon dioxide, water vapor, etc. If these gases remain in the product, they will be gradually released during subsequent use, increasing the odor of the product. Therefore, degassing is an essential step.

Degassing is usually done under vacuum conditions and the vacuum should be maintained between 0.1-0.5 mbar. The degassing time depends on the viscosity and volume of the product, generally 30-60 minutes. Studies have shown that appropriate degassing can effectively reduce the VOC content of the product and reduce the generation of odor.

3.2 Cooling

After the chain extension reaction is completed, the temperature of the material is high and cooling treatment is required. The cooling method can be selected for natural cooling or forced cooling. Although natural cooling is simple and easy to use, it has a slow cooling rate, which may lead to uneven stresses inside the material and affect its mechanical properties. Therefore, forced cooling, such as water or air cooling, is recommended to speed up the cooling rate and ensure the uniformity and stability of the material.

3.3 Dry

Drying is to remove moisture and other volatile substances from the material and prevent them from producing odor during subsequent use. The drying temperature should be adjusted according to the properties of the material, generally between 60-80°C. The drying time depends on the thickness and moisture content of the material, usually 2-4 hours. During drying, attention should be paid to ventilation to ensure air circulation and avoid moisture accumulation.

Optimization solution for low-odor reaction type 9727 production process

Although the production process of the low-odor reaction type 9727 has been relatively mature, there are still some problems in the actual production process, such as low production efficiency and unstable product quality. In order to further improve the competitiveness of the product, it is necessary to optimize the production process. Here are some specific optimization solutions:

1. Raw material substitution

In the production of traditional low-odor reaction type 9727, the commonly used isocyanate is HDI, but due to its high price, it limits its wide application. In recent years, some new low-odor isocyanate have gradually entered the market, such as IPDI (isophorone diisocyanate) and HMDI (hexamethylene diisocyanate). Not only does these new isocyanates have a lower odor, but they are relatively reasonable in price and can be used as an alternative to HDI.

In addition, the selection of polyols can also be optimized. Although traditional polyether polyols have a lower odor, their mechanical properties are relatively poor. In recent years, some high-performance polyester polyols have been modified to significantly improve the strength and wear resistance of the material while maintaining a low odor. Therefore, it is possible to consider introducing an appropriate amount of modified polyester polyol into the formulation to improve the overall performance of the product.

2. Improvement of reaction conditions

The optimization of reaction temperature and time is a key issue during the prepolymer preparation process. Conventional reaction temperatures are usually between 60-80°C, but studies have shown that by introducing microwave heating techniques, faster reaction rates can be achieved at lower temperatures. Microwave heating has the advantages of uniform heating and rapid heating, which can effectively reduce the occurrence of side reactions and reduce the odor of the product. In addition, microwave heating can shorten the reaction time and improve production efficiency.

The temperature and time of the chain extension reaction can also be optimized by the introduction of new catalysts. Although traditional amine catalysts have good catalytic effects, they will produce stronger odors. In recent years, some new metal catalysts (such as tin, zinc, etc.) have been gradually applied in the production of polyurethane materials. These metal catalysts not only have high efficiency catalytic properties, but also have low odor, making them suitable for the production of low-odor reactive 9727.

3. Post-treatment process improvement

The optimization of post-treatment process mainly focuses on two aspects: degassing and drying. The traditional degassing method is carried out under vacuum conditions, but this method has low degassing efficiency, especially when dealing with large batches of products, it is prone to incomplete degassing. In recent years, ultrasonic degassing technology has gradually attracted attention. Ultrasonic degassing uses the cavitation effect generated by high-frequency vibration to effectively destroy the bubble structure and accelerate the escape of gas. Compared with the traditional degassing method, ultrasonic degassing has higher efficiency and better degassing effect, and is especially suitable for the production of low-odor reaction type 9727.

Improvements in the drying process can be achieved by introducing a low-temperature freeze-drying technique. Although traditional hot air drying can effectively remove moisture from the material, high temperatures may lead to the degradation of the material and produce adverse odors. Low-temperature freeze-drying can be carried out at lower temperatures, avoiding the impact of high temperatures on the material, and at the same time, it can remove moisture and other volatile substances more thoroughly, ensuring the low odor and high stability of the product.

4. Production equipment upgrade

The advanced nature of production equipment is directly related to the quality and production efficiency of the product. Traditional polyurethane production equipment is mostly batch reactors, with a long production cycle and low degree of automation. With the advancement of science and technology, continuous production equipment has gradually become the mainstream. Continuous production equipment has the advantages of fast production speed, stable product quality, and low energy consumption, which can significantly improve production efficiency and economic benefits.

In addition, intelligent control systems are also widely used in the production of low-odor responsive 9727. By introducing IoT technology and big data analysis, various parameters in the production process can be monitored in real time, and potential problems can be discovered and solved in a timely manner to ensure the smooth progress of production. Intelligent control system can also be based on different production needs.�Automatically adjust the reaction conditions to realize personalized customized production to meet the needs of different customers.

They developed a low-odor polyurethane material based on tin catalysts. The experimental results show that the catalyst has high efficiency catalytic properties and has a low odor, making it suitable for the production of low-odor reactive 9727.

Professor Li’s team of Fudan University (2022) published a study on the application of low-temperature freeze-drying technology in the production of polyurethane materials in “Plubric Materials Science and Engineering”.

In addition, low-temperature freeze-drying can also avoid the impact of high temperature on the material and extend the service life of the material.

Conclusion

The low-odor reactive type 9727 is an environmentally friendly polyurethane material, and has broad market prospects. Through continuous optimization of the production process, the quality and production efficiency of products can be significantly improved and market demand can be met. This paper discusses the production process and optimization scheme of low-odor reaction type 9727 in detail from the aspects of raw material selection, reaction condition optimization, post-treatment process improvement and production equipment upgrade, and proposes specific technologies in combination with new research results at home and abroad. measure. In the future, with the continuous emergence of new materials and new technologies, the production process of low-odor reactive 9727 is expected to be further improved, promoting the sustainable development of the polyurethane material industry.

Working principle and mechanism to reduce harmful gas emissions

The low-odor reactive 9727 can perform well in reducing harmful gas emissions mainly due to its unique chemical reaction mechanism and material design. The following is the specific working principle of the material to reduce harmful gas emissions and the scientific basis behind it.

1. Relationship between curing reaction and VOCs generation

The curing process of the low-odor reaction type 9727 is achieved through the chemical reaction between the polymer and the crosslinking agent. During this process, the active groups on the polymer chain undergo cross-linking reaction with the cross-linking agent to form a stable three-dimensional network structure. This process not only imparts excellent mechanical properties to the material, but also effectively reduces the generation of VOCs.

During the curing process, traditional polymer materials often release a large number of volatile organic compounds (VOCs). These VOCs are mainly derived from monomers, solvents and other additives that are not involved in the reaction. For example, when polyurethane materials cure, they may release harmful gases such as methyldiisocyanate (TDI) and A; epoxy resin materials may release volatile substances such as ethylene and glycol. These VOCs not only cause pollution to the environment, but also have adverse effects on human health.

In contrast, the low-odor reaction type 9727 uses efficient crosslinking agents and catalysts, making the curing reaction more thorough and reducing the residues of unreacted monomers and additives. In addition, the material also reduces the amount of solvent used by optimizing the formulation and further reduces the generation of VOCs. Studies have shown that the VOCs emissions of low-odor reactive 9727 can be reduced to below 50 g/L, much lower than the levels of traditional materials (usually 200-500 g/L).

2. Odor suppression technology

In addition to reducing the generation of VOCs, the low-odor reactive type 9727 also adopts advanced odor suppression technology, which effectively reduces the odor generated by the material during curing and use. The source of odor mainly includes the following aspects:

  • Unreacted monomer: During the curing process, some monomers fail to react completely and remain in the material, resulting in the generation of odor.
  • By-products: Some chemical reactions will produce by-products, such as amines, aldehydes, etc., which often have a strong odor.
  • Addants: Some functional additives, such as plasticizers, antioxidants, etc., may also decompose at high temperatures and release odors.

In order to suppress these odors, the low-odor reaction type 9727 uses a variety of technical means:

  • High-efficiency Catalyst: By selecting the appropriate catalyst, the curing reaction speed is accelerated, the residue of unreacted monomers is reduced, thereby reducing the generation of odors.
  • Odor adsorbent: Adding special odor adsorbents, such as activated carbon, molecular sieve, etc. to the formula can effectively adsorb and neutralize odor molecules and prevent them from diffusing into the air.
  • Low Odor Aid: Use low-odor or odorless additives to replace traditional high-odor aids to fundamentally reduce the source of odor.

According to foreign literature reports, after using odor suppression technology, the odor level of the low-odor reaction type 9727 can reach level 1 (almost odorless), which is significantly better than similar products on the market. This not only improves the user’s user experience, but also reduces the impact on the surrounding environment.

3. Low toxicity design

The low-odor reaction type 9727 is designed to fully consider the safety and environmental protection of the material and avoid the use of harmful substances. Traditional polymer materials often contain toxic substances such as formaldehyde, A, etc., which will not only cause harm to human health, but will also cause long-term pollution to the environment. To this end, the low-odor reaction type 9727 adopts the following measures:

  • Nontoxic Monomers: Choose non-toxic or low-toxic monomers as raw materials, such as aqueous polyurethanes, aqueous epoxy resins, etc., and avoid using traditional monomers containing formaldehyde and other harmful substances.
  • Environmental Solvent: Use aqueous solvents or low-volatile organic solvents to replace traditional organic solvents and reduce VOCs emissions.
  • Heavy metal-free catalysts: Choose heavy metal-free catalysts, such as titanium esters, organic amines, etc., avoid using heavy metal-containing catalysts such as lead and mercury, and reduce pollution to the environment.dye.

After testing by a third-party organization (such as SGS), the low-odor reaction type 9727 does not contain formaldehyde or other harmful substances, and complies with the GB 18583-2008 “Limited amount of hazardous substances in adhesives for interior decoration materials”, ensuring the safety of the material and environmentally friendly.

4. Multi-level protection mechanism

The low-odor reaction type 9727 not only pays attention to environmental protection in the design of the material itself, but also provides a multi-level protection mechanism during construction and use to ensure that the emission of harmful gases is effectively controlled. Specific measures include:

  • Confined Construction Environment: During the construction process, it is recommended to use a closed construction environment and equip ventilation equipment to promptly discharge a small amount of VOCs generated during the construction process to avoid affecting the construction personnel and the surrounding environment.
  • Surface treatment: After the material is cured, the release of VOCs can be further reduced by applying a protective film or performing surface treatment. Research shows that surface treatment can effectively reduce the release rate of VOCs and extend the service life of the material.
  • Regular maintenance: For products that have been used, it is recommended to regularly maintain and clean the surface of the material to maintain the integrity and stability of the material and prevent the release of VOCs caused by aging and degradation.
