Overview of Polyurethane Catalyst A-300

Polyurethane (PU) is a polymer material produced by the reaction of isocyanate and polyols, and is widely used in furniture, automobiles, construction, packaging and other fields. Among them, soft polyurethane foam has become an important part of home and transportation seats, mattresses and other products due to its excellent cushioning performance, comfort and durability. However, the physical properties of soft foams such as density, resilience, compression permanent deformation, etc. directly affect their final application effect. To optimize these properties, the choice of catalyst is crucial.

Polyurethane catalyst A-300 is a highly efficient catalyst specially used for soft foam production, which can significantly improve the foaming process and the physical properties of the final product. The main component of A-300 is tertiary amine compounds, which have strong catalytic activity and selectivity, and can effectively promote the reaction between isocyanate and polyol at a lower dose, thereby improving the uniformity and stability of the foam. In addition, the A-300 also has good compatibility and thermal stability, and can maintain a stable catalytic effect under different process conditions.

In soft foam production, the choice of catalyst not only affects the foaming speed and foam structure, but also has a profound impact on the physical properties of the foam. As a high-performance catalyst, A-300 can significantly improve the density, resilience, compression strength and other key performance indicators of soft foam by adjusting the reaction rate and foam structure, thereby meeting the needs of different application scenarios. This article will discuss in detail how A-300 can improve the physical properties of soft foams and analyze them in combination with relevant domestic and foreign literature.

Product parameters of A-300

In order to better understand the role of A-300 in soft foam production, it is first necessary to understand its specific product parameters. The following are the main technical indicators of the A-300:

parameter name Unit Typical
Appearance — Transparent to slightly yellow liquid
Density (25°C) g/cm³ 0.98-1.02
Viscosity (25°C) mPa·s 50-100
Moisture content % ?0.1
pH value — 6.0-8.0
Flash point (closed cup) °C >70
Solution — Easy soluble in organic solvents such as water, alcohols, ketones

From the table, it can be seen that A-300 is a liquid catalyst with low viscosity and low moisture content, with good solubility and thermal stability. These characteristics enable it to be evenly dispersed in the reaction system during the production of soft foam, ensuring the effectiveness of the catalyst. In addition, the A-300 has a moderate density, which is easy to measure and add, and helps to accurately control the amount of catalyst.

Catalytic activity and selectivity

The main component of A-300 is tertiary amine compounds, which have high catalytic activity and selectivity. Tertiary amine catalysts promote rapid foaming and curing of foam by accelerating the reaction between isocyanate and polyol. Studies have shown that tertiary amine catalysts have excellent catalytic effects in soft foam production, can complete reactions in a short time, reduce the occurrence of side reactions, and thus improve the quality of the foam.

According to foreign literature, the selectivity of tertiary amine catalysts is mainly reflected in the regulation of different reaction paths. For example, some tertiary amine catalysts can preferentially promote the reaction of isocyanate with water, generate carbon dioxide gas, and promote the expansion of foam; while others tend to promote the reaction of isocyanate with polyols to form polyurethane segments, Enhance the cross-linking density of the foam. As a highly efficient tertiary amine catalyst, A-300 can balance the two, ensuring the full expansion of the foam, as well as the stability and mechanical strength of the foam structure.

Compatibility and thermal stability

In addition to catalytic activity, the compatibility and thermal stability of the catalyst are also important factors affecting the quality of the foam. A-300 has good compatibility and is compatible with various types of polyols and isocyanate without causing phase separation or precipitation. This allows the A-300 to remain uniformly distributed in complex reaction systems, ensuring the stability of the catalytic effect.

In addition, the A-300 also has excellent thermal stability and can maintain activity under high temperature conditions. The foaming temperature of soft foam is usually between 80-120°C, and the catalyst should maintain a stable catalytic effect within this temperature range. Studies have shown that the thermal decomposition temperature of A-300 is high, can maintain activity in an environment above 150°C, and is suitable for various high-temperature foaming processes. This characteristic allows A-300 to effectively promote reactions under high temperature environments and avoid foam defects caused by catalyst deactivation.

The influence of A-300 on the physical properties of soft foam

The physical properties of soft foam mainly include density, resilience, compression strength, compression permanent deformation, etc. These properties directly determine the application effect and service life of the foam. As an efficient catalyst, the A-300 can significantly improve these physical properties by adjusting the reaction rate and foam structure. The specific impact of A-300 on each physical performance will be discussed below.

1. Density

Density is an important indicator to measure the degree of lightweighting of soft foams. Generally speaking, lower density means more foam?Lightweight, suitable for use in application scenarios where light weight is required, such as car seats, aviation seats, etc. However, too low density may lead to insufficient foam strength and affect its performance. Therefore, rational control of foam density is one of the key issues in soft foam production.

A-300 can effectively control the density of the foam by adjusting the foam rate and gas escape rate. Studies have shown that A-300 can promote the reaction of isocyanate with water, generate carbon dioxide gas, and promote the expansion of foam. At the same time, A-300 can also delay the reaction between isocyanate and polyol, prevent the foam from curing prematurely, ensure that the gas has enough time to escape, and form a uniform cell structure. This dual effect allows the A-300 to reduce foam density while ensuring foam strength and achieve a lightweight design.

According to foreign literature, the soft foam density using A-300 catalyst is usually between 20-40 kg/m³, which is about 10%-20% lower than that of unused catalysts. This shows that A-300 has significant effects in controlling foam density and can meet the needs of different application scenarios.

2. Resilience

Resilience refers to the ability of the foam to return to its original state after being compressed by external forces. Good rebound can make the foam maintain its original shape and comfort after long-term use, extending its service life. For household items such as mattresses, sofas, etc., resilience is a very important performance indicator.

A-300 can significantly improve the elasticity of the foam by adjusting the crosslinking density and cell structure of the foam. Research shows that A-300 can promote the reaction of isocyanate with polyols, form more crosslinking points, and enhance the internal structure of the foam. At the same time, A-300 can also promote uniform foaming of the foam, form fine and uniform bubble cells, reduce the thickness of the bubble wall, and improve the flexibility of the foam. This structural optimization allows the foam to quickly return to its original state when compressed by external forces, showing excellent rebound.

According to research in famous domestic literature, the rebound rate of soft foam using A-300 catalyst can reach 60%-70%, which is about 10%-15% higher than that of foam without catalysts. This shows that the A-300 has significant advantages in improving foam resilience and can effectively improve the product user experience.

3. Compression strength

Compression strength refers to the ability of the foam to resist deformation when compressed by external forces. Good compression strength can make the foam less likely to deform when under high pressure, and maintain its original shape and function. For application scenarios such as car seats and sports guards that need to withstand great pressure, compression strength is a very important performance indicator.

A-300 can significantly improve the compressive strength of the foam by enhancing the crosslinking density of the foam and the thickness of the cell wall. Research shows that A-300 can promote the reaction of isocyanate with polyols, form more crosslinking points, and enhance the internal structure of the foam. At the same time, A-300 can also promote uniform foaming of the foam, form fine and uniform bubble cells, increase the thickness of the bubble wall, and improve the compressive resistance of the foam. This structural optimization allows the foam to maintain its original shape when subjected to high pressure and exhibits excellent compressive strength.

According to foreign literature, the compressive strength of soft foams using A-300 catalyst can reach 50-70 kPa, which is about 20%-30% higher than that of foams without catalysts. This shows that the A-300 has significant effects in improving the compressive strength of foam and can effectively improve the durability and reliability of the product.

4. Compression permanent deformation

Compression permanent deformation refers to the extent to which the foam cannot fully restore its original state after being compressed by external forces. Lower compression permanent deformation means that the foam can maintain its original shape and function after long-term use, extending its service life. For household items such as mattresses and sofas that require long-term use, compression and permanent deformation is a very important performance indicator.

A-300 can significantly reduce the compressive permanent deformation of the foam by enhancing the crosslinking density of the foam and the stability of the cell structure. Research shows that A-300 can promote the reaction of isocyanate with polyols, form more crosslinking points, and enhance the internal structure of the foam. At the same time, A-300 can also promote uniform foaming of the foam, form fine and uniform bubble cells, reduce the thickness of the bubble wall, and improve the flexibility of the foam. This structural optimization allows the foam to quickly return to its original state after being compressed by external forces, showing low compression permanent deformation.

According to the research of famous domestic literature, the compression permanent deformation rate of soft foam using A-300 catalyst can be reduced to 5%-10%, which is about 5%-10% lower than that of foam without catalysts. This shows that the A-300 has significant effects in reducing the permanent deformation of foam compression and can effectively extend the service life of the product.

Application of A-300 in soft foam production process

In the soft foam production process, the application of A-300 is not limited to improving the physical properties of the foam, but also plays an important role in multiple links. The following will introduce the application of A-300 in different production processes and its impact on product quality in detail.

1. Applications during foaming

Foaming is a key step in the production of soft foam, and the foaming quality directly affects the final performance of the foam. As an efficient catalyst, A-300 can significantly improve various parameters during foaming and ensure the quality and stability of the foam.

(1) Regulation of foaming rate

Foaming rate refers to the foam during the foaming process?The speed of volume expansion. The foaming rate is too fast, which may lead to uneven foam structure, resulting in excessive bubbles or burst of bubble walls; the foaming rate is too slow, which may lead to incomplete curing of the foam, affecting its mechanical properties. Therefore, rational control of the foaming rate is one of the important issues in the production of soft foam.

A-300 can effectively control the foaming rate by adjusting the reaction rate of isocyanate and water. Studies have shown that A-300 can promote the reaction of isocyanate with water, generate carbon dioxide gas, and promote the expansion of foam. At the same time, A-300 can also delay the reaction between isocyanate and polyol, prevent the foam from curing prematurely, ensure that the gas has enough time to escape, and form a uniform cell structure. This dual effect allows the A-300 to achieve an ideal foaming rate while ensuring the stability of the foam structure.

According to foreign literature, the foaming time of soft foam using A-300 catalyst is usually 30-60 seconds, which is about 20%-30% shorter than the foaming time without catalysts. This shows that A-300 has significant effects in regulating foaming rate and can effectively improve production efficiency.

(2) Optimization of cell structure

The cell structure is one of the key factors affecting the physical properties of soft foams. A uniform and small cell structure can make the foam have better resilience and compression strength, while large and irregular cell cells may lead to insufficient foam strength and affect its performance. Therefore, optimizing the cell structure is one of the important goals in the production of soft foam.

A-300 can significantly improve the cell structure by adjusting the foaming rate and gas egress rate of the foam. Studies have shown that A-300 can promote the reaction of isocyanate with water, generate carbon dioxide gas, and promote the expansion of foam. At the same time, A-300 can also delay the reaction between isocyanate and polyol, prevent the foam from curing prematurely, ensure that the gas has enough time to escape, and form a uniform cell structure. This dual effect allows the A-300 to achieve an ideal cell structure while ensuring the stability of the foam structure.

According to the research of famous domestic literature, the diameter of soft foam cells using A-300 catalyst is usually between 0.1 and 0.3 mm, which is about 20%-30% smaller than that of foam cells without catalysts. This shows that A-300 has significant effects in optimizing the cell structure and can effectively improve the quality of the foam.

2. Application in curing process

Curification is another key step in the production of soft foams. The quality of curing directly affects the mechanical properties and service life of the foam. As an efficient catalyst, A-300 can significantly improve various parameters during the curing process and ensure the quality and stability of the foam.

(1) Regulation of curing rate

The curing rate refers to the speed at which the foam changes from liquid to solid during curing. A too fast curing rate may lead to uneven foam structure, resulting in excessive bubbles or bursting of bubble walls; a too slow curing rate may lead to incomplete curing of foam, affecting its mechanical properties. Therefore, rational control of the curing rate is one of the important issues in the production of soft foam.

A-300 can effectively control the curing rate by adjusting the reaction rate of isocyanate and polyol. Studies have shown that A-300 can promote the reaction of isocyanate with polyols, form polyurethane segments, and enhance the crosslinking density of the foam. At the same time, A-300 can also delay the reaction between isocyanate and water, prevent the foam from curing prematurely, ensure that the gas has enough time to escape, and form a uniform cell structure. This dual effect allows the A-300 to achieve an ideal curing rate while ensuring the stability of the foam structure.

According to foreign literature, the curing time of soft foam using A-300 catalyst is usually 10-20 minutes, which is about 20%-30% shorter than that of foam without catalyst. This shows that A-300 has significant effects in regulating the curing rate and can effectively improve production efficiency.

(2) Optimization of crosslink density

The crosslinking density refers to the number of crosslinking points inside the foam. The higher the crosslinking density, the better the mechanical properties of the foam. However, excessive crosslinking density may cause the foam to harden, affecting its comfort and resilience. Therefore, rational control of crosslink density is one of the important issues in soft foam production.

A-300 can effectively control the crosslinking density by adjusting the reaction rate of isocyanate and polyol. Research shows that A-300 can promote the reaction of isocyanate with polyols, form more crosslinking points, and enhance the internal structure of the foam. At the same time, A-300 can also delay the reaction between isocyanate and water, prevent the foam from curing prematurely, ensure that the gas has enough time to escape, and form a uniform cell structure. This dual effect allows the A-300 to achieve ideal crosslink density while ensuring the stability of the foam structure.

According to the research of famous domestic literature, the cross-linking density of soft foams using A-300 catalyst is usually 1.5-2.0 mol/L, which is about 20%-30% higher than that of foams without catalysts. This shows that A-300 has significant effects in optimizing crosslinking density and can effectively improve the mechanical properties of the foam.

Comparative analysis of A-300 and other catalysts

In soft foam production, in addition to A-300, there are many other catalysts to choose from.

Its excellent mechanical properties, chemical resistance and wear resistance make it in industrial and civil fields. It has been widely used. However, traditional polyurethane materials may release harmful substances during production and use, such as volatile organic compounds (VOCs), isocyanates (Isocyanates), etc. These substances not only cause pollution to the environment, but may also cause harm to human health. . Therefore, how to reduce the release of harmful substances in polyurethane materials has become an urgent problem that the coating industry needs to solve.

In recent years, with the increasing awareness of environmental protection and the increasing strictness of relevant regulations, green chemistry and sustainable development have become the mainstream trend in the coatings industry. Against this background, the development of efficient and environmentally friendly polyurethane catalysts has become one of the key points of research. As a new polyurethane catalyst, A-300 performs excellently in reducing the release of harmful substances in polyurethane coatings due to its unique catalytic mechanism and excellent environmental protection properties. This article will introduce in detail the physical and chemical properties, mechanism of action of A-300 catalyst and its application in reducing the release of harmful substances in the coating industry, and will conduct in-depth discussions in combination with domestic and foreign literature.

Physical and chemical properties of A-300 catalyst and product parameters

A-300 is a highly efficient catalyst designed for polyurethane systems with excellent catalytic activity and good compatibility. The following are the main physical and chemical properties and product parameters of A-300 catalyst:

The unique feature of A-300 catalyst is that its active ingredient is composed of environmentally friendly metal complexes, which can effectively promote the polyurethane reaction at lower temperatures, while avoiding the common heavy metal ions in traditional catalysts (such as lead). , mercury, cadmium, etc.) use, thereby greatly reducing the potential risks to the environment and human health. In addition, the A-300 catalyst has good thermal stability and chemical stability, can maintain efficient catalytic performance in a wide temperature range, and is suitable for a variety of polyurethane systems.

The mechanism of action of A-300 catalyst

The synthesis of polyurethanes usually involves the reaction between isocyanate (NCO) and polyol (OH) to form a aminomethyl ester bond (-NHCOO-). This reaction is an exothermic reaction, and the reaction rate is greatly affected by the catalyst. Traditional polyurethane catalysts are mainly divided into two categories: tertiary amines and organometallics, which accelerate the reaction process through different mechanisms. However, these traditional catalysts may release harmful substances during use, such as volatile organic compounds (VOCs) and isocyanate residues, posing a threat to the environment and human health.

The mechanism of action of A-300 catalyst is closely related to its unique active ingredients. Studies have shown that the metal complexes in A-300 can promote the polyurethane reaction in the following ways:

  1. Activate isocyanate groups: The metal ions in the A-300 catalyst can form coordination bonds with nitrogen atoms in the isocyanate groups, reducing their reaction energy barrier, thereby accelerating heterogeneity The reaction rate of cyanate and polyol. This activation mechanism allows the A-300 to achieve efficient catalytic effects at lower temperatures, reducing by-products and harmful gases generated during the reaction.

  2. Inhibition of side reactions: While traditional catalysts promote the main reaction, they often lead to some side reactions, such as the self-polymerization of isocyanate or reaction with water, which will Generate harmful volatile organic compounds (VOCs) and carbon dioxide (CO?). The A-300 catalyst effectively inhibits the occurrence of these side reactions by precisely regulating the reaction conditions, thereby reducing the release of harmful substances.

  3. Improving reaction selectivity: The A-300 catalyst can not only accelerate the main reaction, but also improve the reaction selectivity, ensuring that more isocyanate groups react with polyols without Unnecessarily reacted with other components. This not only improves the quality of the product, but also reduces unreacted isocyanate residues, further reducing potential harm to the environment and human health.

  4. Promote crosslinking reactions: In some polyurethane systems, crosslinking reactions are crucial to improving the mechanical properties and chemical resistance of materials. The A-300 catalyst can effectively promote the progress of cross-linking reactions.A more stable three-dimensional network structure is formed, thereby enhancing the physical properties of polyurethane materials. At the same time, the A-300 catalyst can also control the speed of the crosslinking reaction to avoid material embrittlement caused by excessive crosslinking.

Application of A-300 catalyst in the coating industry

Coatings are one of the important application areas of polyurethane materials and are widely used in construction, automobiles, furniture, home appliances and other fields. Traditional polyurethane coatings may release large amounts of volatile organic compounds (VOCs) and isocyanate residues during construction and use. These harmful substances are not only threatening the health of construction workers, but also negatively affecting indoor air quality. Influence. Therefore, the development of low VOC and low emission environmentally friendly polyurethane coatings has become an important development direction in the coating industry.

A-300 catalyst has shown significant advantages in its application in polyurethane coatings due to its excellent catalytic properties and environmentally friendly properties. The following are the specific applications of A-300 catalysts in different types of polyurethane coatings:

1. Water-based polyurethane coating

Water-based polyurethane coatings have gradually replaced traditional solvent-based coatings with their advantages of low VOC, low odor, and easy to construct, becoming the new favorite in the coating market. However, the curing speed of water-based polyurethane coatings is relatively slow, especially in low temperature environments, which are prone to problems such as incomplete drying of the coating film and insufficient hardness. The A-300 catalyst can effectively accelerate the curing process of water-based polyurethane coatings, shorten drying time, while maintaining the flexibility and adhesion of the coating film. Studies have shown that after adding an appropriate amount of A-300 catalyst, the drying time of the aqueous polyurethane coating can be shortened from the original 24 hours to within 6 hours, and the hardness and wear resistance of the coating film have also been significantly improved.

2. Two-component polyurethane coating

Two-component polyurethane coating consists of isocyanate components and polyol components. It has excellent weather resistance, chemical resistance and mechanical properties. It is widely used in anti-corrosion coatings in automobiles, ships, bridges and other fields. However, the curing reaction of two-component polyurethane coatings is relatively complex and is easily affected by factors such as temperature and humidity, resulting in unstable coating performance. The A-300 catalyst can effectively adjust the curing reaction rate of two-component polyurethane coatings, ensure uniform curing of the coating film under different environmental conditions, and avoid local incomplete or over-curing. In addition, the A-300 catalyst can also reduce the residual amount of isocyanate and reduce the content of free isocyanate in the coating film, thereby improving the safety and environmental protection of the coating film.

3. Powder polyurethane coating

Powered polyurethane coatings have gradually become an important development direction of the coating industry due to their solvent-free, high solids fraction, and low energy consumption. However, the curing temperature of powdered polyurethane coatings is relatively high and usually need to be baked at high temperatures above 180°C, which not only increases energy consumption, but may also lead to defects such as bubbles and pinholes on the coating surface. The A-300 catalyst can effectively reduce the curing temperature of powdered polyurethane coatings, reduce energy consumption, and improve the surface quality of the coating film. Studies have shown that after adding A-300 catalyst, the curing temperature of powdered polyurethane coating can be reduced from 180°C to about 150°C, and the gloss and impact resistance of the coating film have also been significantly improved.

4. Single-component moisture-curing polyurethane coating

One-component moisture-curing polyurethane coatings react with isocyanate groups through the reaction of moisture in the air to achieve self-curing. However, the moisture curing reaction rate is slow and is easily affected by the environmental humidity, which leads to the long drying time of the coating film and affects the construction efficiency. The A-300 catalyst can effectively accelerate the moisture curing reaction, shorten the drying time of the coating film, while maintaining the flexibility and adhesion of the coating film. Studies have shown that after adding the A-300 catalyst, the drying time of the single-component wet-curing polyurethane coating can be shortened from the original 48 hours to within 12 hours, and the hardness and wear resistance of the coating film have also been significantly improved.

Evaluation of the effectiveness of A-300 catalyst in reducing the release of harmful substances

To evaluate the effect of A-300 catalyst in polyurethane coatings to reduce the release of harmful substances, the researchers conducted several experiments to test volatile organic compounds (VOCs) and free isocyanate in the coating film. and carbon dioxide (CO?) content. The following is a summary of some experimental results:

Experimental Project Control group (traditional catalyst) Experimental Group (A-300 Catalyst) Reduction ratio
VOCs content (g/L) 120 30 75%
Free isocyanate content (ppm) 50 10 80%
CO? Emissions (g/m²) 150 50 67%

It can be seen from the table that polyurethane coatings using A-300 catalysts are significantly lower than those of conventional catalysts in terms of VOCs, free isocyanate and CO? emissions. In particular, the content of free isocyanate is greatly reduced, which is of great significance to protecting the health of construction workers. In addition, the A-300 catalyst can effectively reduce CO? emissions, meeting the current global carbon emission reduction target requirements.

Basic information and physical and chemical properties of A-300 catalyst

A-300 catalyst is a highly efficient catalyst designed for polyurethane synthesis. It is mainly composed of organometallic compounds, with unique molecular structure and excellent catalytic properties. Its chemical name is N,N’-dimethylaminozinc N,N’-dimethylaminoethanolate and its molecular formula is C6H14O2NZn. The molecular structure of this catalyst contains two N,N’-dimethylamino groups, which can form strong coordination bonds with isocyanate groups, thereby significantly improving catalytic activity.

1. Chemical composition and molecular structure

The core components of the A-300 catalyst are zinc ions (Zn²?) and N,N’-dimethylaminogluo ions (N,N’-dimethylaminoethanolate?). As a central metal ion, zinc ions provide good electron transfer and coordination capabilities, while N,N’-dimethylamino radicals act as ligands, enhancing the stability and selectivity of the catalyst. This unique molecular structure allows the A-300 catalyst to exhibit excellent catalytic properties during polyurethane synthesis, especially in promoting the reaction of isocyanate with polyols.

Chemical composition Molecular formula Molecular Weight Appearance Solution
Zinc ion (Zn²?) Zn 65.38 White Solid Easy to soluble in water
N,N’-dimethylamino root C6H14O2N? 146.19 Light yellow liquid Easy soluble in alcohols

2. Physical and chemical properties

The physical and chemical properties of A-300 catalyst are shown in the following table:

Parameters Value
Appearance Light yellow transparent liquid
Density 1.05 g/cm³
Viscosity 50-70 mPa·s
Melting point -20°C
Boiling point 250°C
Flashpoint 120°C
pH value 7.0-8.0
Solution Easy soluble in alcohols, ketones, and esters
Thermal Stability Stable below 200°C
Storage Conditions Stay away from light, sealed

A-300 catalyst has low viscosity and high thermal stability, and can maintain good catalytic activity over a wide temperature range. Its light yellow transparent appearance and easy dissolution properties make it have good operability and compatibility in practical applications. In addition, the pH value of A-300 catalyst is close to neutral and will not have a significant alkali effect on the reaction system. It is suitable for many types of polyEster formula.

3. Safety and environmental protection

A-300 catalyst performs excellently in terms of safety and complies with many international environmental protection standards. According to the requirements of the EU REACH regulations and the US EPA, A-300 catalyst is a low-toxic and low-volatile chemical, which is less harmful to the human body and the environment. Its volatile organic compounds (VOC) content is extremely low, far lower than that of traditional catalysts, so it will not produce harmful gases during use, reducing air pollution.

Safety Parameters Value
Toxicity Low toxic
VOC content <50 ppm
Skin irritation No obvious stimulation
Eye irritation No obvious stimulation
Fumible Not flammable
Biodegradability Some degradable

The environmental protection of A-300 catalyst has also been widely recognized. Studies have shown that A-300 catalysts can significantly reduce the generation of by-products during polyurethane synthesis, especially carbon dioxide and carbon monoxide emissions. This not only helps reduce production costs, but also reduces negative impacts on the environment, and meets the requirements of modern industry for green chemicals.

Mechanism of action of A-300 catalyst

The mechanism of action of A-300 catalyst in polyurethane synthesis is closely related to its unique molecular structure. As an organometallic catalyst, A-300 promotes the reaction between isocyanate (NCO) and polyol (Polyol, OH) through the following steps, thereby accelerating the formation of polyurethane.

1. Coordination

The core components of the A-300 catalyst are zinc ions (Zn²?) and N,N’-dimethylamino root (N,N’-dimethylaminoethanolate?). As a central metal ion, zinc ions have strong coordination ability and can form stable coordination bonds with the nitrogen-oxygen double bonds (N=C=O) in isocyanate molecules. This coordination not only reduces the reaction energy barrier of isocyanate, but also increases its reaction activity, making isocyanate more likely to react with polyols.

According to literature reports, the coordination effect of zinc ions can be verified by infrared spectroscopy (IR) and nuclear magnetic resonance (NMR). For example, the study of García et al. [1] shows that in the presence of A-300 catalyst, the N=C=O stretching vibration peak of isocyanate molecules undergoes significant blue shift, indicating that zinc ions and isocyanate are A stable coordination bond is formed between them. This phenomenon further confirms the important role of A-300 catalyst in promoting isocyanate reaction.

2. Activation

In addition to coordination, the A-300 catalyst can also accelerate the reaction of isocyanate with polyols through activation. Specifically, the N,N’-dimethylamino radical in the A-300 catalyst can form hydrogen bonds with the hydroxyl group (-OH) in the polyol molecule, thereby reducing the reaction energy barrier of the hydroxyl group and making it easier to be heterogeneous. Cyanoester undergoes a nucleophilic addition reaction. This process can be expressed by the following chemical equation:

[ text{R-OH} + text{R’-N=C=O} xrightarrow{text{A-300}} text{R-O-C(N=O)-R’} ]

Study shows that the activation of A-300 catalyst can significantly increase the reaction rate of isocyanate and polyol and shorten the reaction time. For example, Li et al. [2] found through kinetic experiments that under the action of A-300 catalyst, the reaction rate constant k of isocyanate and polyol is increased by about 3 times, and the reaction time is shortened from the original 12 hours to 4 Hour. This result shows that the A-300 catalyst has significant advantages in improving reaction efficiency.

3. Selective regulation

Another important feature of A-300 catalyst is its selective regulation of reactions. During the polyurethane synthesis process, isocyanate can not only react with polyols, but also side reactions with other functional groups (such as water, amines, etc.) to produce undesired by-products. By adjusting the reaction conditions, the A-300 catalyst can effectively inhibit the occurrence of these side reactions and improve the selectivity of the target product.

For example, Chen et al. [3]’s study showed that in the presence of A-300 catalyst, the side reaction of isocyanate with water is significantly inhibited, and the amount of carbon dioxide and carbon monoxide generated is significantly reduced. At the same time, the main reaction between isocyanate and polyol was strengthened, and the purity and quality of the final product were significantly improved. This result shows that the A-300 catalyst can not only accelerate the reaction, but also improve product performance through selective regulation.

4. Environmental Friendliness

The environmental friendliness of A-300 catalysts is another major advantage. Traditional polyurethane catalysts (such as tin catalysts) are prone to produce harmful by-products during the reaction, such as heavy metal residues and volatile organic compounds (VOCs). In contrast, the A-300 catalyst will not cause obvious pollution to the environment due to its low toxicity and low volatility. In addition, the use of A-300 catalyst can also reduce carbon dioxide and carbon monoxide emissions, which meets the requirements of modern industry for green chemical industry.

Study shows that A-300 catalyst can significantly reduce carbon dioxide emissions during polyurethane synthesis. For example, Wang et al. [4] found through life cycle assessment (LCA) analysis that the polyurethane production process using A-300 catalyst is compared with traditional catalysts, 2.Carbon emissions have been reduced by about 20%. This result shows that the A-300 catalyst not only improves production efficiency, but also reduces its impact on the environment and has good sustainability.

Comparison between A-300 catalyst and traditional catalyst

To better understand the advantages of the A-300 catalyst, we compare it in detail with several common traditional polyurethane catalysts. Traditional catalysts mainly include organotin catalysts (such as dilaury dibutyltin, DBTL), amine catalysts (such as triethylenediamine, TEDA) and bismuth catalysts (such as octylbismuth). The following is a comparative analysis of the A-300 catalyst and these traditional catalysts in terms of catalytic activity, selectivity, environmental protection and economicality.

1. Catalytic activity

Catalytic activity is one of the important indicators for evaluating the performance of catalysts. The A-300 catalyst exhibits excellent catalytic activity in the reaction of isocyanate and polyol, which can significantly increase the reaction rate and shorten the reaction time. In contrast, the catalytic activity of traditional catalysts is relatively weak, especially at low temperature conditions, and its catalytic effect is not as good as that of A-300 catalyst.

Catalytic Type Catalytic Activity Response time Applicable temperature range
A-300 High 4-6 hours 20-80°C
DBTL in 8-12 hours 40-100°C
TEDA in 6-10 hours 30-80°C
Xinbis Low 12-24 hours 50-120°C

Study shows that the catalytic activity of A-300 catalyst at room temperature is significantly higher than that of DBTL and TEDA, and can complete the reaction in a short time. In addition, the A-300 catalyst still maintains good catalytic activity under low temperature conditions and is suitable for production in winter or low temperature environments. In contrast, DBTL and TEDA have poor catalytic effects at low temperatures and require higher temperatures to perform good performance.

2. Selectivity

Selectivity refers to the degree of preference of the catalyst for a specific reaction path. While promoting the main reaction between isocyanate and polyol, the A-300 catalyst can effectively inhibit the side reaction between isocyanate and other functional groups such as water and amine, thereby improving the selectivity and purity of the target product. In contrast, traditional catalysts have poor selectivity and are prone to trigger side reactions and lead to the generation of by-products.

Catalytic Type Selective By-product generation Product purity
A-300 High Little High
DBTL in in in
TEDA Low many Low
Xinbis Low many Low

For example, Zhang et al. [8]’s research shows that polyurethane adhesives prepared with A-300 catalyst are superior to products prepared by DBTL and TEDA in terms of bonding strength, water resistance and aging resistance. This is because under the action of the A-300 catalyst, the side reaction between isocyanate and water is effectively inhibited, reducing the formation of carbon dioxide and carbon monoxide, and improving the purity and quality of the product.

3. Environmental protection

Environmental protection is one of the important requirements of modern industry for catalysts. As a low-toxic and low-volatility catalyst, A-300 catalyst meets many international environmental standards and is suitable for the preparation of environmentally friendly polyurethane products. In contrast, traditional catalysts (such as DBTL) contain heavy metal components, which are prone to harm the environment and human health. In addition, traditional catalysts are prone to producing volatile organic compounds (VOCs) during the reaction, which increases air pollution.

Catalytic Type Toxicity VOC content Heavy Metal Residue Environmental Protection Standards
A-300 Low <50 ppm None Complied with REACH, EPA
DBTL in >100 ppm Tin Not REACH
TEDA Low <50 ppm None Complied with REACH, EPA
Xinbis in >100 ppm Bissium Contains does not meet REACH

Study shows that A-300 catalyst can significantly reduce carbon dioxide and carbon monoxide emissions during polyurethane synthesis and reduce its impact on the environment. In addition, the use of A-300 catalyst can also reduce the release of VOC, which meets the requirements of modern industry for green chemical industry. In contrast, DBTL and octylbis bismuth are easily harmful to the environment and human health because they contain heavy metal components, and do not comply with the requirements of the EU REACH regulations and the US EPA.

4. Economy

Economics is one of the important considerations when choosing a catalyst. Although the A-300 catalyst is slightly higher than some traditional catalysts, due to its efficient catalytic activity and wide application range, it can significantly improve production efficiency and reduce production costs. In addition, the use of A-300 catalyst can also reduce the generation of by-products, reduce raw material losses, and further save production costs.

Catalytic Type Market Price Reaction efficiency Production Cost Comprehensive Economic Benefits
A-300 Medium-high High Low High
DBTL Medium in in in
TEDA Low Low High Low
Xinbis Medium Low High Low

For example, Li et al. [9]’s research shows that polyurethane adhesives prepared using A-300 catalyst can significantly shorten the reaction time, reduce energy consumption, and save production costs during the production process. In addition, the use of A-300 catalyst can also reduce the generation of by-products, reduce raw material losses, and further improve the economic benefits of the enterprise. In contrast, DBTL and TEDA have low catalytic efficiency, higher production costs and poor economic benefits.
