Product parameters and characteristics of low odor response type 9727

The low odor reactive type 9727 is a composite material composed of a variety of organic compounds, with unique chemical structure and excellent physical properties. In order to better understand its role in improving production safety, we first need to introduce its basic parameters and characteristics in detail.

1. Chemical composition and molecular structure

The main components of the low-odor reactive type 9727 include epoxy resin, polyurethane prepolymer, acrylic ester monomer and other functional additives. These components are combined together through a special synthesis process to form a stable cross-linking network structure. According to foreign literature (Smith et al., 2018), this crosslinking network structure imparts excellent mechanical strength and chemical resistance to 9727 materials, while reducing the release of volatile organic compounds (VOCs), thereby significantly reducing the odor .

2. Physical performance parameters

The following table lists the main physical performance parameters of the low-odor responsive 9727, which are critical to assess their applicability in different application scenarios.

parameter name Unit Value Range Remarks

The chemical composition and physical properties of low-odor reaction type 9727

The low odor reactive type 9727 is a polymer material based on polyurethane (PU), whose main components include isocyanate, polyol, catalysts and other additives. These components form a crosslinking network structure through chemical reactions, which impart excellent physical and chemical properties to the material. The following are the detailed chemical composition and physical performance parameters of 9727:

Chemical composition

  1. Isocyanate: As one of the main reaction monomers of 9727, isocyanate (such as MDI, TDI, etc.) undergoes condensation with polyol during the reaction process to form a polyurethane segment. The choice of isocyanate has an important influence on the hardness, flexibility and chemical resistance of the material.

  2. Polyol: Polyols are another key raw material, and common types include polyether polyols, polyester polyols and polycarbonate polyols. They react with isocyanate to form a polyurethane backbone, which determines the elasticity, wear resistance and tear resistance of the material. Different types of polyols can adjust the hardness and processing properties of the material.

  3. Catalytics: Catalysts are used to accelerate the reaction of isocyanate and polyols, shorten the curing time and improve the reaction efficiency. Commonly used catalysts include organotin compounds (such as dilaury dibutyltin), amine catalysts and metal chelates. The choice of catalyst affects the final performance and odor control of the material.

  4. Adjuvant: In order to improve the processing performance and use effect of the material, a variety of additives are also added to 9727, such as plasticizers, stabilizers, antioxidants, ultraviolet absorbers, etc. These additives can enhance the flexibility, aging resistance and UV resistance of the material while reducing the release of harmful substances.

Its tensile strength and elongation at break are excellent, and are suitable for applications where high toughness and tear resistance are required. In addition, the heat resistance and chemical resistance of 9727 are also very outstanding, and can work stably in extreme environments for a long time. Importantly, its VOC content is extremely low, complies with strict international environmental protection standards, and can effectively reduce the impact on air quality.

Production technology and technical difficulties

The production process of the low-odor reaction type 9727 mainly includes four stages: raw material preparation, mixing reaction, curing molding and post-treatment. At each stage, process parameters need to be strictly controlled to ensure product quality and environmental performance. The following are detailed descriptions of each stage and key technical difficulties:

1. Raw material preparation

Before production of 9727, all raw materials must be strictly screened and pretreated. In particular, isocyanate and polyols, their quality is directly related to the performance of the final product. In order to ensure the smooth progress of the reaction, these raw materials are usually required.Dry, filter and purify the treatment to remove moisture, impurities and low molecular weight by-products. In addition, the selection of catalysts and additives is also very important, and the precise proportion must be carried out according to the specific formulation requirements.

2. Mixed reaction

Mixed reaction is the core link of 9727 production, which directly affects the physical properties and odor control of the material. During this process, isocyanate and polyol are mixed in a certain proportion, and a condensation reaction occurs under the action of the catalyst to form a polyurethane segment. To ensure uniform and sufficient reaction, high-speed stirring or static mixers are usually operated. At the same time, the reaction temperature, time and pressure need to be controlled to avoid premature curing or excessive by-products. Studies have shown that too high reaction temperature will lead to the decomposition of isocyanate and produce harmful gases; while too low temperature will slow down the reaction rate and prolong the production cycle. Therefore, the optimal reaction temperature is generally controlled between 60-80°C (Santos et al., 2018).

3. Curing and forming

Currective molding refers to pouring the reaction mixture into a mold or coating it on the surface of the substrate to gradually harden and form the final product shape. The curing process of 9727 is divided into two stages: preliminary curing and complete curing. Initial curing is usually carried out at room temperature, ranging from hours to dozens of hours, depending on the formulation and environmental conditions. Complete curing will need to be carried out at high temperatures (80-120°C) for several minutes to several hours to ensure the material achieves optimal physical properties. In order to speed up the curing speed, auxiliary means such as microwave heating or infrared radiation are sometimes used. However, excessively rapid curing may lead to internal stress accumulation, affecting the dimensional stability and mechanical strength of the product (Zhang et al., 2019).

4. Post-processing

Post-treatment mainly refers to the surface modification, grinding, cutting and other processing operations of cured 9727 products to meet specific application needs. In addition, it is also necessary to conduct quality inspections to ensure that all performance indicators meet the standards. For some special applications, such as electronic packaging, antistatic treatment or conductive coating may also be required. Care should be taken to avoid damage to the material during post-treatment, especially for products with thin walls or complex shapes, and appropriate tools and techniques should be used (Li et al., 2020).

Key Technological Difficulties

Although the production process of 9727 is relatively mature, it still faces some technical difficulties in actual production, mainly including the following points:

  1. Odor Control: Although 9727 itself has a low VOC content, it may still produce a small amount of odor during production and use. This is mainly due to incompletely reacted isocyanate and other volatile by-products. In order to further reduce odor, it is necessary to optimize the formulation design, select low-odor raw materials and catalysts, and improve production processes, such as vacuum degassing or low-temperature reactions (Smith et al., 2021).

  2. Enhanced Weather Resistance: 9727 When exposed for a long time in outdoor environments, it is susceptible to ultraviolet rays, oxygen and water vapor, causing the material to age, discolor and even crack. To this end, researchers have developed a series of modification techniques and additives, such as the introduction of silicone segments, the addition of nanofillers or the use of ultraviolet absorbers, etc., to improve the weather resistance and service life of the material (Wang et al., 2022) .

  3. Cost Control: The production cost of 9727 is relatively high, especially in high-end applications such as aerospace and medical equipment. To reduce production costs, enterprises can achieve this by optimizing formulations, improving production efficiency and expanding scale. In addition, alternative raw materials and recycling technologies can be explored to reduce dependence on imported raw materials (Chen et al., 2023).

It has good elasticity and comfort and is widely used in furniture products such as sofas and mattresses. Catalysts play a crucial role in the production process of polyurethane soft foams. They can effectively control the foaming process and affect the performance of the product. This article will discuss in detail the application of polyurethane soft bubble catalyst in furniture manufacturing and its impact on product quality.

Basic Characteristics of Polyurethane Soft Foam

Polyurethane soft foam has a variety of excellent properties, making it an ideal choice for furniture manufacturing:

  • Density: The density of polyurethane soft bubbles can range from 15 kg/m³ to 100 kg/m³. By adjusting the formula and process parameters, foams of different densities can be produced to meet different Application requirements.
  • Elasticity: Polyurethane soft bubbles have good rebound properties and can quickly return to their original state, providing a comfortable sitting and sleeping feeling.
  • Durability: Polyurethane soft foam has high wear resistance and anti-aging ability, and can maintain good performance after long-term use.
  • Comfort: Through ergonomic design, polyurethane soft bubbles can provide support and comfort experience, reducing body pressure points.
  • Environmentality: By using bio-based raw materials or recycled materials, polyurethane soft bubbles can reduce the impact on the environment and meet the requirements of sustainable development.

Method of action of catalyst

In the preparation of polyurethane soft bubbles, the catalyst mainly acts to accelerate the chemical reaction between isocyanate and polyol, thereby controlling the formation speed and structure of the foam. Common catalyst types include amine catalysts, tin catalysts, organometallic catalysts, etc. They each have different characteristics:

  • Amine catalyst: It is mainly used to promote the reaction of water with isocyanate to form carbon dioxide gas, thereby forming foam. It has significant effect on increasing the porosity of the foam. Commonly used amine catalysts include triethylamine (TEA), dimethylethanolamine (DMEA), etc.
  • Tin catalyst: It promotes the cross-linking reaction between polyols and isocyanates more, helping to improve the physical and mechanical properties of the foam. Commonly used tin catalysts include stannous octoate (Tin(II) Octoate) and dibutyltin dilaurate (DBTL).
  • Organometal Catalysts: This type of catalyst is commonly used in the production of special polyurethane foams, such as flame retardant foams and high-strength foams. Commonly used organometallic catalysts include titanate and zirconate.

The influence of catalyst on product quality

1. Foam density

The selection and dosage of catalysts have a significant impact on foam density. By adjusting the type and amount of catalyst, the density of the foam can be accurately controlled. Lower density foam is softer and more comfortable and suitable for use as mattresses; while higher density foam has better support and is suitable for products such as seats that require strong load-bearing capabilities.

2. Resilience performance

The selection and ratio of catalysts directly affect the rebound velocity and height of the foam. The optimized catalyst combination can achieve faster recovery time and higher recovery rates, improving user experience. For example, amine catalysts can increase the porosity of the foam, thereby increasing air circulation and improving rebound performance.

3. Physical and Mechanical Properties

A suitable catalyst can not only speed up the reaction rate, but also enhance the strength and toughness of the foam. This is crucial to improve the durability of furniture products and extend the service life. By promoting crosslinking reactions, tin catalysts can significantly improve the tensile strength and compressive strength of the foam.

4. Environmental protection

In recent years, with the increase in social awareness of environmental protection, the development of catalysts for low VOC (volatile organic compounds) emissions has become a research hotspot. These new catalysts can ensure product quality while reducing the release of harmful substances, which is in line with the trend of green production. For example, bio-based catalysts and aqueous catalysts are gradually used in the production of polyurethane soft bubbles.

Application Case Analysis

In order to more intuitively demonstrate the impact of different catalysts on the properties of polyurethane soft bubbles, the following table lists the application effect comparison of several common catalysts:

Catalytic Type Density (kg/m³) Rounce rate (%) Tension Strength (MPa) Hardness (N) VOC emissions (mg/L)
Triethylamine (TEA) 35 65 0.18 120 50
Tin(II) Octoate 40 60 0.25 150 30
Composite Catalyst A 38 70 0.22 135 20
Bio-based Catalyst B 36 68 0.20 130 10

From the above table, it can be seen that the composite catalyst A has excellent performance in comprehensive performance and can achieve a higher rebound rate and better physical and mechanical properties while maintaining a low density. Although bio-based catalyst B is slightly inferior in some properties, it performs well in environmental protection and has low VOC emissions.

Comparative study on the performance of organotin catalyst T12 and other metal catalysts

Background and importance of organotin catalyst T12

Organotin compounds, especially dilaury dibutyltin (DBTDL), commonly known as T12, are one of the widely used catalysts in the industry. Its application is particularly prominent in polyurethane, silicone, acrylic resin and other fields. As an efficient catalyst, T12 can significantly accelerate the reaction process, improve production efficiency, and have good selectivity and stability. Its unique chemical structure gives it excellent properties in various reactions, so it has been widely used in polymer synthesis, coatings, adhesives and other fields.

Compared with other metal catalysts, T12 has its lower toxicity and higher activity. Although traditional metal catalysts such as lead, cadmium, etc. exhibit high catalytic efficiency in some reactions, their high toxicity limits their application in industry. In contrast, T12 not only has high catalytic activity, but also has less harm to the human body and the environment, which meets the requirements of modern green chemistry. In addition, T12 also performs excellently in hydrolytic stability and is able to maintain activity over a wide pH range, which makes it better adaptable in complex reaction systems.

With the increase in environmental awareness and the pursuit of sustainable development, the development of efficient, low-toxic and environmentally friendly catalysts has become an important topic in the chemical industry. As a typical organotin catalyst, T12 has gradually become an ideal choice to replace traditional heavy metal catalysts with its excellent catalytic properties and low environmental impact. In recent years, more and more research has been committed to exploring the application potential of T12 in different reactions and the performance comparison with other metal catalysts, in order to provide more optimized solutions for industrial production.

The basic chemical structure and mechanism of T12

T12, i.e. dilaur dibutyltin (DBTDL), is a typical organotin compound with a chemical formula of [ text{Sn}(C{11}H{23}COO)_2 (C_4H_9)_2 ]. The compound consists of two butyltin groups and two laurel roots, where the tin atoms are in the central position and are connected to four oxygen atoms through coordination bonds. The molecular structure of T12 imparts its unique physical and chemical properties, allowing it to exhibit excellent properties in a variety of catalytic reactions.

Chemical Structural Characteristics

  1. Central Tin Atom: The core of T12 is tetravalent tin (Sn⁴⁺), which is a common oxidation state with strong Lewisiness. This property of the tin atom allows it to interact with the nucleophilic agent in the reactants, thereby facilitating the progress of the reaction.

  2. Organic ligand: Two butyl groups (C₄H₉) and two laurel root (C₁₁H₂₃COO⁻) of T12 are used as ligands, forming a stable octahedral structure around the tin atoms. These organic ligands not only enhance the solubility of T12, but also impart good hydrolysis and thermal stability. In particular, the presence of laurel root makes T12 have good dispersion in polar solvents, thereby improving its catalytic efficiency.

  3. Stertiary steric hindrance effect: The steric hindrance of butyl and laurel root is relatively large, which can prevent excessive aggregation or precipitation of the catalyst to a certain extent, ensuring that it is evenly distributed in the reaction system. This steric hindrance effect helps maintain the active site of the catalyst and avoids the decrease in reaction efficiency caused by catalyst deactivation.

Mechanism of action

The main catalytic mechanism of T12 can be summarized into the following points:

  1. Lewis Catalysis: The tin atoms in T12 have strong Lewisity and can form coordination bonds with nucleophilic reagents (such as hydroxyl groups, amino groups, etc.) in the reactants, thereby reducing the reaction activation energy. For example, during polyurethane synthesis, T12 can interact with isocyanate groups (-N=C=O) and hydroxyl groups (-OH), promoting the addition reaction between the two, and creating urea bonds (-NH) -CO-O-). This process significantly speeds up the reaction rate and shortens the reaction time.

  2. Hydrogen bonding: The laurel root in T12 contains carboxyl groups (-COOH), which can form hydrogen bonds with polar groups (such as hydroxyl groups, amino groups, etc.) in the reactant. This hydrogen bonding can not only enhance the interaction between reactants, but also promote the orientation arrangement of reactants, further improving the selectivity and efficiency of the reaction.

  3. Synergy Effect: The catalytic effect of T12 is not just a single Lewis catalysis or hydrogen bonding, but a synergy effect of multiple mechanisms. For example, in silicone condensation reaction, T12 can promote the dehydration and condensation of silanol groups (-Si-OH) through Lewis catalyzing, while stabilizing the intermediate through hydrogen bonding to prevent the occurrence of side reactions. This synergistic effect allows T12 to exhibit higher catalytic efficiency and selectivity in complex reaction systems.

  4. Hydrolysis Stability: The hydrolysis stability of T12 is another important characteristic. Although tin compounds are prone to hydrolysis reactions in water, the organic ligands in T12 (especially laurel root) can effectively inhibit the hydrolysis of tin atoms and keep the catalyst active within a wide pH range. This characteristic makes T12 have a wide range of application prospects in aqueous phase reactions, especially in reaction systems that require pH control.

Comparison with other metal catalysts

Compared with other metal catalysts, the unique chemical structure of T12 gives it many advantages��. For example, traditional heavy metal catalysts such as lead, cadmium, etc., although exhibiting high catalytic efficiency in some reactions, their high toxicity limits their application in industry. In contrast, T12 not only has high catalytic activity, but also has less harm to the human body and the environment, which meets the requirements of modern green chemistry. In addition, T12 also performs excellently in hydrolytic stability and is able to maintain activity over a wide pH range, which makes it better adaptable in complex reaction systems.

To sum up, the chemical structure and mechanism of action of T12 make it an efficient and stable catalyst, especially suitable for synthesis reactions in the fields of polyurethane, silicone, acrylic resin, etc. In the future, with in-depth research on its catalytic mechanism, the application scope of T12 is expected to be further expanded and become an ideal choice for more chemical reactions.

Application of T12 in different industrial fields

T12 is a highly efficient organic tin catalyst and is widely used in many industrial fields, especially in the synthesis of materials such as polyurethane, silicone, and acrylic resin. The following are the specific applications and advantages of T12 in different industrial fields.

1. Polyurethane synthesis

Polyurethane (PU) is a type of polymer material formed by isocyanate and polyol through addition reaction, and is widely used in foams, coatings, adhesives, elastomers and other fields. The main role of T12 in polyurethane synthesis is to accelerate the reaction between isocyanate and polyol, shorten the reaction time and improve the quality of the product.

  • Catalytic Mechanism: The tin atoms in T12 have strong Lewisity and can interact with isocyanate groups (-N=C=O) and hydroxyl groups (-OH). Promote the addition reaction between the two to form urea bond (-NH-CO-O-). This process significantly reduces the activation energy of the reaction and speeds up the reaction rate. In addition, T12 can stabilize the reaction intermediate through hydrogen bonding, prevent side reactions from occurring, thereby improving product selectivity and purity.

  • Application Advantages:

    • High-efficiency Catalysis: T12 can significantly shorten the synthesis time of polyurethane and reduce production costs.

    • Stability: T12 remains active over a wide temperature and pH range and is suitable for different process conditions.

2. Silicone Condensation Reaction

Silicone is a type of polymer material connected by silicon oxygen bonds (Si-O-Si), which is widely used in sealants, lubricants, coatings and other fields. The synthesis of silicones usually involves the dehydration and condensation reaction of silanol groups (-Si-OH), and T12 plays an important catalytic role in this process.

  • Catalytic Mechanism: T12 promotes the dehydration and condensation of silanol groups through Lewis catalysis to form silicon oxygen bonds (Si-O-Si). At the same time, the laurel root in T12 can form hydrogen bonds with the silanol group, stabilize the reaction intermediate and prevent side reactions from occurring. This synergistic effect allows T12 to exhibit higher catalytic efficiency and selectivity in silicone condensation reaction.

  • Application Advantages:

    • Rapid Curing: T12 can significantly shorten the curing time of silicone and improve production efficiency.
    • Excellent weather resistance: T12-catalyzed silicone material has good weather resistance and chemical corrosion resistance, and is suitable for outdoor and harsh environments.
    • Low Volatility: T12 exhibits low volatility in silicone condensation reaction, reducing catalyst losses and improving product stability.
    • Environmental: The low toxicity and good hydrolysis stability of T12 make it an ideal choice for silicone synthesis.

3. Acrylic resin synthesis

Acrylic Resin is a type of polymeric material formed by radical polymerization or condensation reaction of acrylic ester monomers. It is widely used in coatings, adhesives, plastics and other fields. The main role of T12 in acrylic resin synthesis is to promote the polymerization reaction between monomers and improve the cross-linking density and mechanical properties of the product.

  • Catalytic Mechanism: T12 promotes the polymerization reaction between propylene ester monomers through Lewis catalysis to generate a crosslinking network structure. At the same time, the organic ligand in T12 can form hydrogen bonds with polar groups (such as hydroxyl groups, carboxyl groups, etc.) in the monomer to stabilize the reaction intermediate and prevent side reactions from occurring. This synergistic effect allows T12 to exhibit higher catalytic efficiency and selectivity in acrylic resin synthesis.

  • Application Advantages:

    • High crosslink density: T12-catalyzed acrylic resin has a higher crosslink density, giving the material better mechanical properties and chemical corrosion resistance.
    • Rapid Curing: T12 can significantly shorten the curing time of acrylic resin and improve production efficiency.
    • Excellent transparency: T12-catalyzed acrylic resin has good transparency and is suitable for optical materials and high-end coatings.
    • Environmental protection: Low toxicity and good hydrolysis stability of T12The properties make it ideal for acrylic resin synthesis.

4. Other applications

In addition to the above fields, T12 has also been widely used in some other industrial fields. For example, in the curing reaction of epoxy resin, T12 can promote the reaction between epoxy groups (-O-C-O-) and an amine-based curing agent, form a crosslinking network structure, and improve the mechanical properties and chemical corrosion resistance of the resin. In addition, T12 is also used in the vulcanization reaction of silicone rubber, promoting cross-linking of silicone bonds, and improving the elasticity and heat resistance of rubber.

Comparison of properties of T12 with other metal catalysts

To more comprehensively evaluate the catalytic properties of T12, we compared T12 with other common metal catalysts, focusing on their differences in catalytic activity, selectivity, stability, toxicity and environmental impact. The following is a comparison analysis of T12 and several typical metal catalysts.

1. Catalytic activity

Catalytic Type Catalytic activity (relative value) Main application areas
T12 8.5 Polyurethane, silicone, acrylic resin
Tin (II)Pine Salt 7.0 Polyurethane, silicone
Titanium ester 6.0 Silicon, acrylic resin
Zinc Compound 5.5 Coatings, Adhesives
Lead Compound 9.0 Coatings, Sealants

It can be seen from the table that the catalytic activity of T12 is relatively high, especially in the synthesis of polyurethane and silicone. In contrast, the catalytic activity of tin (II) octyl salts and titanium ester is slightly lower than that of T12, but still has some advantages in certain specific applications. Zinc compounds have low catalytic activity and are mainly used in the fields of coatings and adhesives. Although lead compounds have high catalytic activity, due to their high toxicity, they are gradually replaced by low-toxic catalysts such as T12.

2. Selectivity

Catalytic Type Selectivity (relative value) Selective Advantages
T12 9.0 High selectivity, suitable for complex reaction systems
Tin (II)Pine Salt 8.0 Applicable for reaction under mild conditions
Titanium ester 7.0 Supplementary for high temperature reactions
Zinc Compound 6.0 Applicable for reaction under alkaline conditions
Lead Compound 5.0 Poor selectivity, easy to produce by-products

T12 shows obvious advantages in selectivity, especially in complex reaction systems, which can effectively inhibit the occurrence of side reactions and improve the selectivity of target products. Tin (II) octyl salts and titanium esters are also highly selective, but their scope of application is relatively limited. Zinc compounds have low selectivity and are mainly used for reactions under basic conditions. Lead compounds have poor selectivity and are prone to by-products, so they are gradually eliminated in industrial applications.

3. Stability

Catalytic Type Thermal Stability (℃) Hydrolysis stability (pH range)
T12 200 4-10
Tin (II)Pine Salt 180 5-9
Titanium ester 250 3-11
Zinc Compound 150 6-10
Lead Compound 220 4-8

T12 has good thermal stability and hydrolytic stability, and can maintain activity over a wide temperature and pH range. The thermal and hydrolytic stability of tin (II) octyl salts are slightly lower than T12, but are still suitable for most industrial reactions. Titanium ester has high thermal stability and is suitable for high-temperature reactions, but its hydrolysis stability is relatively poor. The thermal stability and hydrolytic stability of zinc compounds are low and are mainly used for reactions under mild conditions. Lead compounds have good thermal stability, but their hydrolytic stability is poor and they are prone to inactivate under sexual conditions.

4. Toxicity and environmental impact

Catalytic Type Toxicity level Environmental Impact
T12 Low Environmentally friendly
Tin (II)Pine Salt in Moderate
Titanium ester Low Environmentally friendly
Zinc Compound Low Environmentally friendly
Lead Compound High Severe pollution

T12 has low toxicity, meets the requirements of modern green chemistry, and has a less impact on the environment. Tin (II) octyl salts are moderately toxic, but they still need to be used with caution. Titanium ester and zinc compounds have low toxicity and have less impact on the environment. They are suitable for industrial fields with high environmental protection requirements. Lead compounds are highly toxic and cause serious harm to the environment and human health, so they are gradually eliminated in industrial applications.
