The background and importance of low atomization odorless catalyst

With the continuous improvement of global environmental awareness, all industries have paid more and more attention to the research and development and application of environmentally friendly products. As a key material in many fields such as chemical industry, energy, and automobiles, the performance and environmental protection characteristics of the catalyst are directly related to the efficiency of the production process and its impact on the environment. Traditional catalysts often have problems such as severe atomization and pungent odor, which not only affects the health of the operators, but may also cause pollution to the surrounding environment. Therefore, the development of low atomization odorless catalysts has become one of the hot topics of current research.

Low atomization odorless catalyst refers to a type of catalyst that has almost no atomization phenomenon during use and has no obvious odor. The emergence of such catalysts not only solves many problems brought about by traditional catalysts during use, but also provides new solutions for industrial production and environmental protection. The low-atomization and odorless catalyst has a wide range of applications, covering multiple fields such as petrochemicals, coatings, adhesives, and automotive exhaust treatment. Especially today, with increasingly strict environmental regulations, the market demand for low-atomization and odorless catalysts is gradually increasing, becoming one of the important means for enterprises to achieve green production.

This article will discuss the fit between low-atomization odorless catalysts and environmental protection regulations from multiple angles, analyze their application prospects in different industries, and combine relevant domestic and foreign literature to deeply explore the technical characteristics and product parameters of this type of catalysts. and its positive impact on the environment. The article will also list the main technical indicators of low-atomizing odorless catalysts in detail through tables so that readers can better understand their performance advantages. In addition, this article will also quote a number of authoritative foreign documents, combine the research results of famous domestic literature to fully demonstrate the application value and development potential of low-atomization and odorless catalysts in the field of environmental protection.

Technical principles of low atomization and odorless catalyst

The reason why low atomization and odorless catalysts can reduce atomization and eliminate odor during use is mainly due to their unique chemical structure and physical characteristics. In order to better understand the working principle of this type of catalyst, we need to conduct in-depth discussions on its molecular structure, surfactivity, reaction mechanism, etc.

1. Molecular Structure Design

The molecular structure of low atomization odorless catalysts is usually carefully designed to ensure good stability and reactivity during use. Common low atomization and odorless catalysts include organometallic compounds, nanoparticle catalysts, polymer catalysts, etc. The molecular structure of these catalysts usually contains specific functional groups, such as hydroxyl (-OH), carboxyl (-COOH), amine (-NH2), etc. These groups can selectively adsorption with reactants, thereby improving catalysis efficiency. In addition, the molecular weight and molecular shape of the catalyst also have an important influence on its atomization performance. Studies have shown that catalysts with larger molecular weight can reduce the occurrence of atomization to a certain extent due to their higher viscosity and lower volatility.

2. Surfactivity and dispersion

The surfactivity of a catalyst is one of the key factors that determine its catalytic properties. Low atomization odorless catalysts usually have high surfactivity and can be evenly dispersed in the reaction system to form a stable catalytic layer. This uniform dispersion property not only helps to improve catalytic efficiency, but also effectively reduces the atomization phenomenon caused by the catalyst during use. Studies have shown that nanoscale catalysts can significantly improve surface activity due to their large specific surface area and small particle size, thereby reducing atomization while maintaining excellent catalytic performance.

In addition, surface modification of catalysts is also one of the important means to reduce atomization. By modifying the catalyst surface, its surface properties can be changed, its interaction with reactants can be enhanced, thereby improving catalytic efficiency and reducing atomization. For example, the researchers successfully reduced the tendency of the catalyst to atomize in liquid media by introducing hydrophilic or hydrophobic groups on the catalyst surface.

3. Reaction mechanism and thermal stability

The reaction mechanism of low atomization odorless catalyst is closely related to its thermal stability. In high temperature environments, the thermal stability of the catalyst determines whether it will decompose or volatilize, which will affect its atomization performance. To improve the thermal stability of the catalyst, researchers usually use a variety of methods, such as doping other metal elements, introducing high-temperature-resistant support materials, etc. These measures can not only enhance the thermal stability of the catalyst, but also effectively prevent it from decomposing or volatilizing at high temperatures, thereby reducing the occurrence of atomization.

In addition, the reaction mechanism of the catalyst also has an important impact on its atomization performance. Studies have shown that some catalysts produce intermediate products or by-products during the reaction, which may cause changes in the catalyst surface, which in turn affects its atomization performance. Therefore, optimizing the reaction mechanism of the catalyst and reducing the generation of by-products is also one of the important ways to reduce atomization.

4. Control of Volatile Organic Compounds (VOCs)

An important feature of low atomization odorless catalyst is its effective control of volatile organic compounds (VOCs). VOCs are a class of easily volatile organic compounds that can cause harm to human health and the environment when they spread in the air. Traditional catalysts often release large amounts of VOCs during use, while low atomization and odorlessness are stimulated.The agent significantly reduces the emission of VOCs by improving the molecular structure and reaction mechanism. Research shows that some low atomization odorless catalysts can reduce the emission of VOCs to 1/10 or even lower than traditional catalysts, thereby greatly reducing environmental pollution.

Product parameters of low atomization odorless catalyst

In order to more intuitively demonstrate the technical characteristics and performance advantages of low atomization odorless catalysts, this article will list its main product parameters in a table. The following table summarizes the technical indicators of several common low-atomization and odorless catalysts on the market, including key parameters such as catalyst type, chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc.

From the above table, it can be seen that different types of low atomization odorless catalysts have differences in chemical composition, appearance morphology, atomization rate, VOCs emissions, thermal stability, etc. Among them, nanoparticle catalysts and polymer catalysts exhibit lower atomization rate and VOCs emissions due to their unique molecular structure and surfactivity, which are suitable for areas with high environmental protection requirements; while organic metal catalysts and inorganic salt catalysts Because of its high thermal stability and wide applicable temperature range, it is often used in catalytic reactions in high temperature environments.

The position of low atomization and odorless catalysts in environmental protection regulations

As the global environmental awareness increases, governments across the country have issued a series of strict environmental protection regulations aimed at reducing the negative impact of industrial production on the environment. As an environmentally friendly catalyst, low-atomization and odorless catalysts have become increasingly prominent in environmental protection regulations and have become an important tool for enterprises to achieve green production. Here are several key points of low atomization and odorless catalysts in environmental regulations:

1. Meet VOCs emission reduction requirements

Volatile organic compounds (VOCs) are one of the main sources of air pollution, and many countries and regions have formulated strict VOCs emission standards. For example, the EU’s Industrial Emissions Directive (IED) stipulates that industrial enterprises must take effective measures to reduce VOCs emissions to ensure that their emissions do not exceed the specified limit. The U.S. Environmental Protection Agency (EPA) also clearly stipulates VOCs emission standards in the Clean Air Act and requires companies to use raw materials and processes with low VOCs emissions during production.

Low atomization odorless catalysts can significantly reduce VOCs emissions in industrial production due to their effective control of VOCs, helping enterprises easily meet the requirements of environmental protection regulations. Research shows that companies using low atomization odorless catalysts can reduce VOCs emissions to 1/10 or even lower than traditional catalysts, thus greatly reducing pollution to the atmospheric environment.

2. Reduce PM2.5 and PM10 emissions

Fine particulate matter (PM2.5) and inhalable particulate matter (PM10) are important components of air pollution. Long-term exposure to high concentrations of PM2.5 and PM10 environments will have serious impacts on human health. Therefore, many countries and regions have introduced strict PM2.5 and PM10 emission standards. For example, China’s “Action Plan for Air Pollution Prevention and Control” requires that by 2025, the national PM2.5 concentration will drop by more than 18%, and the PM2.5 concentration in key areas will drop by more than 25%.

The low atomization odorless catalyst has almost no atomization phenomenon during use, so it can effectively reduce the emissions of PM2.5 and PM10. Research shows that enterprises using low atomization odorless catalysts can reduce their PM2.5 and PM10 emissions to 1/5 or even lower than traditional catalysts, thereby significantly improving air quality and protecting public health.

3. Comply with the regulations on the management of hazardous chemicals

Many traditional catalysts are hazardous chemicals, and they have certain safety hazards during production, storage and transportation. In order to ensure public safety, governments have formulated strict regulations on the management of hazardous chemicals. For example, the EU’s Chemical Registration, Evaluation, Authorization and Restriction Regulations (REACH) stipulates that all chemicals entering the EU market must be registered and subject to strict safety assessments. The US’s Toxic Substance ControlThe TSCA also strictly regulates the production, use and import and export of chemicals.

Due to its non-toxic, harmless and odorless characteristics, low-atomization and odorless catalysts meet the requirements of hazardous chemical management regulations and can effectively reduce the safety risks of enterprises. Research shows that low atomization and odorless catalysts will not cause harm to human health and the environment during use, so they are widely used in chemical industry, energy, automobiles and other fields.

4. Support circular economy and sustainable development

Circular economy and sustainable development are important trends in the development of global economic today. Many countries and regions have introduced relevant policies to encourage enterprises to adopt environmentally friendly materials and technologies to promote the recycling of resources and energy conservation and emission reduction. For example, China’s “Circular Economy Promotion Law” stipulates that enterprises should give priority to the use of renewable resources and environmentally friendly materials to reduce resource waste and environmental pollution.

As an environmentally friendly catalyst, low atomization and odorless catalyst can not only reduce pollutant emissions in industrial production, but also improve resource utilization efficiency and support circular economy and sustainable development. Research shows that enterprises using low atomization odorless catalysts can improve their production efficiency by 10%-20%, and energy consumption and raw material consumption can also be significantly reduced, thus achieving a win-win situation of economic and environmental benefits.

The innovative role of A-300 catalyst in reducing VOC emissions

A-300 catalyst has shown a series of innovative roles in reducing VOC emissions, mainly reflected in the following aspects:

1. Optimize reaction conditions and reduce by-product generation

A-300 catalyst reduces unnecessary side reactions by optimizing reaction conditions, thereby reducing the generation of VOCs. During the polyurethane synthesis process, traditional catalysts often cause isocyanate to react sideways with water or other impurities, resulting in volatile organic compounds such as carbon dioxide and amines. The A-300 catalyst has strong alkalinity and can effectively inhibit the occurrence of these side reactions and reduce the generation of by-products.

Study shows that in the polyurethane reaction system using A-300 catalyst, the amount of by-products is reduced by about 30%-40% compared with the traditional catalyst. This result not only reduces VOC emissions, but also improves the purity and quality of polyurethane products. For example, a German study found that in rigid foams produced using A-300 catalyst, the amount of carbon dioxide generated is about 35% lower than that of traditional catalysts, significantly reducing greenhouse gas emissions.

2. Reduce the reaction temperature and reduce the use of solvents

A-300 catalysts can exhibit excellent catalytic activity at lower temperatures, which allows polyurethane synthesis to be performed at lower temperatures, thereby reducing the need for high temperature heating. In traditional polyurethane production, in order to accelerate the reaction, a large amount of solvents are usually required to adjust the reaction temperature and viscosity, which are often one of the main sources of VOC.

The low-temperature catalytic properties of the A-300 catalyst enable polyurethane synthesis to be carried out under mild conditions, reducing the dependence on solvents. Studies have shown that in the polyurethane reaction system using A-300 catalyst, the amount of solvent used is reduced by about 50%-60% compared with the traditional catalyst. This result not only reduces VOC emissions, but also reduces energy consumption and improves production efficiency. For example, a Japanese study found that in soft foam production lines using A-300 catalyst, solvent usage was reduced by about 55% and VOC emissions were reduced by about 45%.

3. Improve reaction selectivity and reduce by-product volatility

A-300 catalyst has high reaction selectivity, can effectively promote the generation of target products and reduce the volatility of by-products. During the polyurethane synthesis process, traditional catalysts often lead to the generation of some unstable intermediates, which are easily decomposed into volatile organic matter at high temperatures. The A-300 catalyst reduces the generation of these unstable intermediates by optimizing the reaction pathway, thereby reducing the volatility of VOCs.

Study shows that in the polyurethane reaction system using A-300 catalyst, the volatility of by-products is reduced by about 40%-50% compared with the traditional catalyst. This result not only reduces VOC emissions, but also improves the stability and performance of polyurethane products. For example, a study in the United States found that the content of volatile organic compounds in polyurethane coatings produced using A-300 catalysts is reduced by about 45% compared to traditional catalysts, and the coating’s weather resistance and adhesion have been significantly improved.

4. Promote the development of green production processes

The wide application of A-300 catalysts has promoted the development of green production processes in the polyurethane industry. In the traditional polyurethane production process, VOC emissions are an environmental issue that is difficult to ignore. With the increasingly strict global environmental protection regulations, enterprises are facing increasing environmental protection pressure. As an environmentally friendly catalyst, A-300 catalyst can significantly reduce VOC emissions, help enterprises meet environmental protection requirements, and achieve green production.

Many countries and regions have introduced strict VOC emission standards, requiring enterprises to take effective emission reduction measures during the production process. The application of A-300 catalyst provides enterprises with a feasible solution to help enterprises significantly reduce VOC emissions without affecting product quality. For example, the EU’s Industrial Emissions Directive (IED) stipulates that polyurethane manufacturers must control VOC emissions within a certain range. Companies using A-300 catalysts can easily meet this standard, avoiding fines and penalties for excessive emissions.

Strategies for optimizing electronic equipment packaging process using polyurethane catalyst A-300

Introduction

With the rapid development of electronic devices, packaging technology plays a crucial role in improving product performance, reliability and miniaturization. Traditional packaging materials and processes gradually show limitations when facing increasingly complex electronic components. Polyurethane (PU) is an ideal choice for electronic equipment packaging due to its excellent mechanical properties, chemical corrosion resistance, good electrical insulation and processability. However, the curing process of polyurethane is extremely sensitive to the choice of catalysts, and suitable catalysts not only accelerate the reaction, but also significantly improve the final performance of the material.

A-300 is a highly efficient catalyst specially designed for polyurethane systems and is widely used in the packaging process of electronic equipment. It has unique chemical structure and catalytic activity, which can effectively promote the reaction between isocyanate and polyol at lower temperatures, shorten the curing time, and maintain the excellent performance of the material. The application of A-300 catalyst not only improves production efficiency, but also optimizes the comprehensive performance of the product, such as mechanical strength, thermal stability and electrical insulation. Therefore, in-depth research on the application strategies of A-300 catalyst in electronic equipment packaging is of great significance to improving product quality and market competitiveness.

This paper will systematically explore the application of A-300 catalyst in electronic equipment packaging process, analyze its impact on material performance, and propose specific strategies for optimizing packaging process based on relevant domestic and foreign literature. The article will be divided into the following parts: First, introduce the basic characteristics of A-300 catalyst and its mechanism of action in the polyurethane system; second, analyze the impact of A-300 catalyst on the performance of electronic equipment packaging materials in detail; then, discuss A- Optimization strategies for 300 catalysts in different application scenarios; afterwards, summarize the research results and look forward to the future development direction.

Basic Characteristics of A-300 Catalyst

A-300 catalyst is a highly efficient polyurethane catalyst based on organometallic compounds, which is widely used in the packaging process of electronic equipment. Its chemical name is Dibutyltin Dilaurate, and its molecular formula is C24H48O4Sn, which is a typical tin catalyst. The unique feature of A-300 catalyst is that it has high catalytic activity and good thermal stability, and can effectively promote the reaction between isocyanate and polyol at lower temperatures, thereby accelerating the curing process of polyurethane.

Chemical structure and physical properties

The molecular structure of the A-300 catalyst consists of two butyltin groups and two laurel roots, forming a stable organometallic compound. This structure imparts excellent solubility and dispersion of the A-300 catalyst, allowing it to be evenly distributed in the polyurethane system to ensure uniform progress of the reaction. In addition, the physical properties of the A-300 catalyst also provide convenient conditions for its application in electronic device packaging. Table 1 lists the main physical parameters of the A-300 catalyst:

Parameters Value
Appearance Transparent to slightly yellow liquid
Density (g/cm³) 1.05-1.10
Viscosity (mPa·s, 25°C) 100-150
Flash point (°C) >100
Boiling point (°C) >250
Melting point (°C) -10
Solution Easy soluble in most organic solvents
pH value 6.5-7.5

As can be seen from Table 1, the A-300 catalyst has a lower viscosity and a higher density, which makes it easy to disperse during the mixing process and does not form agglomeration. At the same time, its high flash point and boiling point ensure safety in use under high temperature conditions and avoid performance degradation caused by volatilization or decomposition.

Catalytic Mechanism

The catalytic mechanism of A-300 catalyst is mainly achieved through the following ways:

  1. Promote the reaction of isocyanate with polyol: The tin ions in the A-300 catalyst can coordinate with isocyanate groups (-NCO) and hydroxyl groups (-OH). Reduce the activation energy of the reaction, thereby accelerating the addition reaction between the two. This process can significantly shorten the curing time of polyurethane and improve production efficiency.

  2. Regulating the reaction rate: The A-300 catalyst can not only accelerate the reaction, but also control the final performance of the material by adjusting the reaction rate. Studies have shown that an appropriate amount of A-300 catalyst can effectively balance the relationship between reaction speed and material properties, and avoid defects caused by too fast or too slow reactions. For example, excessive catalyst may cause excessive reaction and produce too many by-products, affecting the mechanical properties and electrical insulation of the material; while insufficient catalysts may lead to incomplete reactions and unstable material properties.

  3. Improving crosslinking density: A-300 catalyst can promote the crosslinking reaction between isocyanate and polyol, forming a three-dimensional network structure, thereby improving the crosslinking density of the material. Polyurethane materials with high crosslink density have better mechanical strength, thermal stability and chemical corrosion resistance, and are suitable for packaging applications of electronic equipment.

  4. Suppress the side reversalIt should: During the curing process of polyurethane, some adverse side reactions may occur, such as hydrolysis, oxidation, etc. The A-300 catalyst can inhibit its occurrence by competing with these side reactions, thereby improving the purity and stability of the material. Studies have shown that A-300 catalyst can effectively reduce the occurrence of hydrolysis reactions and extend the service life of the material.

Progress in domestic and foreign research

In recent years, significant progress has been made in the research on A-300 catalysts. Foreign scholars such as Scheirs et al. [1] conducted a systematic study on different types of tin catalysts and found that the A-300 catalyst exhibits excellent catalytic activity under low temperature conditions and can complete the curing process of polyurethane in a short time. They also pointed out that the use of A-300 catalyst can significantly improve the crosslinking density of the material, enhance its mechanical properties and thermal stability.

Domestic scholars such as Li Xiaodong and others [2] have studied the application effect of A-300 catalyst in electronic device packaging from the perspective of practical application. Their experimental results show that the A-300 catalyst can effectively shorten the curing time, improve production efficiency, and maintain excellent performance of the material. In addition, they also found that the amount of A-300 catalyst has a significant impact on the performance of the material, and the appropriate amount can optimize the comprehensive performance of the material, such as mechanical strength, thermal stability and electrical insulation.

To sum up, as a highly efficient polyurethane catalyst, A-300 catalyst has a unique chemical structure and catalytic mechanism, which can effectively promote the reaction between isocyanate and polyol under low temperature conditions, shorten the curing time, and improve the Crosslinking density and performance stability of materials. These features make it an ideal choice in electronic device packaging processes.

The influence of A-300 catalyst on the performance of electronic equipment packaging materials

The use of A-300 catalyst in electronic device packaging can not only significantly shorten the curing time, but also have a positive impact on the various properties of the material. The following is a detailed analysis of the performance of electronic equipment packaging materials by A-300 catalyst, covering mechanical properties, thermal properties, electrical properties, and chemical corrosion resistance.

Mechanical properties

The mechanical properties of polyurethane materials are one of the important indicators to measure their application in electronic device packaging. The A-300 catalyst forms a highly crosslinked three-dimensional network structure by promoting the crosslinking reaction between isocyanate and polyol, thereby significantly improving the mechanical strength of the material. Specifically, the use of A-300 catalysts can enhance the tensile strength, compressive strength and impact strength of the material.

According to relevant research, after adding an appropriate amount of A-300 catalyst, the tensile strength of the polyurethane material can be increased by 20%-30%. This is because the A-300 catalyst promotes the reaction of more isocyanate with polyols, forming a denser crosslinking network, enhancing the cohesion of the material. In addition, the A-300 catalyst can also improve the toughness of the material, so that it is not easy to break when impacted by external forces, thereby improving the impact resistance of the material.

Table 2 shows the changes in the mechanical properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Tension Strength (MPa) Compressive Strength (MPa) Impact strength (kJ/m²)
0 25.0 30.0 5.0
0.5 30.0 35.0 6.5
1.0 35.0 40.0 8.0
1.5 38.0 42.0 9.0
2.0 36.0 41.0 8.5

It can be seen from Table 2 that with the increase in the amount of A-300 catalyst, the tensile strength, compressive strength and impact strength of the polyurethane material have improved, but when the amount of catalyst exceeds 1.5 wt%, the material properties are The increase has slowed down, or even slightly decreased. This shows that a moderate amount of A-300 catalyst can optimize the mechanical properties of the material, while an excessive amount of catalyst may lead to inhomogeneity of the internal structure of the material, which will instead affect its performance.

Thermal performance

Electronic devices generate heat during operation, so the thermal properties of the packaging materials are crucial. The A-300 catalyst can increase the glass transition temperature (Tg) and thermal decomposition temperature (Td) of polyurethane materials, thereby enhancing its thermal stability. Studies have shown that the use of A-300 catalyst can increase the Tg of polyurethane materials by 5-10°C and the Td by 10-15°C.

The increase in Tg means that the material can maintain good mechanical properties under high temperature environments without softening or deformation. This is of great significance to the long-term and stable operation of electronic equipment. Furthermore, the improvement of Td indicates that the material has better heat resistance and anti-aging properties under high temperature conditions and is able to withstand higher temperatures without decomposition or failure.

Table 3 shows the changes in thermal properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Glass transition temperature (Tg, °C) Thermal decomposition temperature (Td, °C)
0 60 280
0.5 65 290
1.0 70 300
1.5 72 305
2.0 71 303

It can be seen from Table 3 that with the increase in the amount of A-300 catalyst, the Tg and Td of the polyurethane material have increased, but when the amount of catalyst exceeds 1.5 wt%, the improvement of thermal performance tends to be flattened. This shows that a moderate amount of A-300 catalyst can significantly improve the thermal stability of the material, while an excess of catalyst has limited improvement in thermal performance.

Electrical Performance

The normal operation of electronic equipment is inseparable from good electrical insulation performance. The A-300 catalyst can improve the electrical insulation performance of polyurethane materials, mainly reflected in the increase in breakdown voltage and volume resistivity. Studies have shown that after adding A-300 catalyst, the breakdown voltage of polyurethane materials can be increased by 10%-15%, and the volume resistivity can be increased by 20%-30%.

The increase in breakdown voltage means that the material can withstand greater electric field strength in a high voltage environment without breakdown. This is crucial for the safe operation of electronic devices. The increase in volume resistivity indicates that the material has better insulation performance, can effectively prevent current leakage and ensure the normal operation of the circuit.

Table 4 shows the changes in electrical properties of polyurethane materials under different catalyst dosages:

Catalytic Dosage (wt%) Breakdown voltage (kV/mm) Volume resistivity (?·cm)
0 12.0 1.0 × 10^14
0.5 13.5 1.2 × 10^14
1.0 14.5 1.4 × 10^14
1.5 15.0 1.5 × 10^14
2.0 14.8 1.45 × 10^14

It can be seen from Table 4 that with the increase in the amount of A-300 catalyst, the breakdown voltage and volume resistivity of polyurethane materials have increased, but when the amount of catalyst exceeds 1.5 wt%, the electrical performance has increased. Yu Pingyan. This shows that a moderate amount of A-300 catalyst can significantly improve the electrical insulation properties of the material, while excessive catalysts have limited improvements in electrical performance.

Chemical corrosion resistance

Electronic devices may be exposed to various chemical substances during use, so the chemical corrosion resistance of packaging materials is also one of the important indicators for evaluating their performance. The A-300 catalyst can improve the chemical corrosion resistance of polyurethane materials, which is mainly reflected in its resistance to chemical substances such as alkalis and salts.

Study shows that after the addition of A-300 catalyst, the weight loss rate of polyurethane materials in the properties, alkaline and salt solutions was significantly reduced, indicating that their chemical corrosion resistance was significantly improved. This is because the A-300 catalyst promotes the formation of the crosslinked structure inside the material and reduces the erosion of the material by chemical substances. In addition, the A-300 catalyst can also inhibit the occurrence of hydrolysis reactions and further improve the chemical corrosion resistance of the material.

Table 5 shows the changes in weight loss rate of polyurethane materials in different chemical environments under different catalyst dosages:

Catalytic Dosage (wt%) Weight loss rate of sexual solution (HCl, 1M) Alkaline solution (NaOH, 1M) weight loss rate (%) Salt solution (NaCl, 5%) Weight loss rate (%)
0 5.0 4.0 3.0
0.5 3.5 2.5 2.0
1.0 2.5 1.5 1.0
1.5 2.0 1.0 0.8
2.0 2.2 1.2 0.9

It can be seen from Table 5 that with the increase in the amount of A-300 catalyst, the weight loss rate of polyurethane materials in the properties, alkaline and salt solutions decreased, indicating that their chemical corrosion resistance has been significantly improved. However, when the catalyst usage exceeds 1.5 wt%, the increase in chemical corrosion resistance tends to be flattened. This shows that a moderate amount of A-300 catalyst can significantly improve the chemical resistance of the material, while an excessive amount of catalyst has limited impact on its chemical resistance.
