2月 15th, 2025 News

Introduction

With the continuous increase in global environmental awareness, reducing emissions of volatile organic compounds (VOCs) has become an important issue of common concern to governments and enterprises in various countries. VOCs are a class of organic compounds that are widely present in industrial production. They not only cause pollution to the environment, but also have potential harm to human health. Studies have shown that VOCs will react photochemically with pollutants such as nitrogen oxides (NOx) in the atmosphere to produce ozone (O3), thereby forming photochemical smoke, which seriously affects air quality. In addition, some VOCs also have the “three-inducing” effects of carcinogenic, teratogenic and mutational. Long-term exposure to high-concentration VOCs environment will cause damage to the human respiratory system, nervous system, etc.

Around the world, many countries and regions have issued strict VOCs emission standards and regulations. For example, the EU issued the Industrial Emissions Directive (IED) in 2016, requiring industrial enterprises to take effective measures to reduce VOCs emissions; the U.S. Environmental Protection Agency (EPA) also clearly stipulates the emission limits of VOCs in the Clean Air Act . As one of the world’s largest chemical producers and consumers, China has also stepped up its efforts to govern VOCs in recent years. In 2020, the Ministry of Ecology and Environment issued the “Volatile Organic Emission Control Standards”, which further standardized the emission management of VOCs.

The polyurethane foam industry is an important contributor among the numerous sources of VOCs emissions. Polyurethane foam is widely used in building insulation, furniture manufacturing, automotive interiors and other fields. The catalysts used in its production process are one of the main sources of VOCs. Traditional polyurethane foam catalysts are mostly tertiary amine compounds. These catalysts are prone to evaporation during the reaction, resulting in higher VOCs emissions. Therefore, the development of new low VOCs catalysts has become the key to solving this problem.

TMR-3 is a semi-hard bubble catalyst developed by internationally renowned chemical companies, specially used in the production of polyurethane foam. This catalyst has excellent catalytic performance and low VOCs emission characteristics, which can significantly reduce the release of VOCs while ensuring product quality. This paper will conduct a detailed evaluation of the performance parameters, application effects and impact on VOCs emissions of TMR-3 catalysts, and discuss its application prospects in the field of environmental protection based on relevant domestic and foreign literature.

Product parameters of TMR-3 catalyst

TMR-3 is a highly efficient catalyst designed for the production of polyurethane semi-hard foam. Its unique chemical structure and physical properties make it excellent in catalytic reactions while having low VOCs emission characteristics. The following are the main product parameters of TMR-3 catalyst:

1. Chemical composition

The main TMR-3The component is modified tertiary amine compounds. After special processing, their molecular structure is more stable, reducing volatility under high temperature conditions. The specific chemical composition is shown in the following table:

Ingredients Content (wt%)
Modified tertiary amine 85-90
Adjuvant additives 5-10
Stabilizer 2-5

Modified tertiary amine is the core active ingredient of TMR-3. It can effectively promote the reaction between isocyanate and polyol and accelerate the foaming and curing process. Auxiliary agents help improve the dispersion and compatibility of the catalyst and ensure their uniform distribution in the polyurethane system. The function of the stabilizer is to prevent the catalyst from decomposing or deteriorating during storage and use, and to extend its service life.

2. Physical properties

The physical properties of TMR-3 determine their operating convenience and safety in practical applications. The following are the main physical parameters of TMR-3:

parameters value

Viscosity (25°C) 100-150 mPa·s
Flashpoint >100°C
Solution Easy soluble in polyols and isocyanates

TMR-3 has good fluidity and solubility, and can be fully mixed with polyurethane raw materials to ensure uniform catalytic reaction. Its high flash point makes the catalyst have better safety during storage and transportation, reducing the risk of fire and explosion.

3. Thermal Stability

Thermal stability is one of the important indicators for measuring the performance of catalysts. TMR-3 exhibits excellent thermal stability under high temperature conditions and is able to maintain its catalytic activity over a wide temperature range. According to laboratory test data, the thermal weight loss rate of TMR-3 is as good as temperatureChanges are shown in the table:

Temperature (°C) Thermal weight loss rate (wt%)
100 0.5
150 1.2
200 2.0
250 3.5

It can be seen from the table that TMR-3 almost volatilizes below 100°C, and its thermal weight loss rate is only 3.5%, far lower than that of traditional tertiary amine catalysts volatility rate. This shows that TMR-3 has strong heat resistance and can maintain stable catalytic performance during the high-temperature foaming of polyurethane foam, thereby effectively reducing VOCs emissions.

4. Catalytic activity

The catalytic activity of TMR-3 is one of its significant advantages. Through comparative experiments, the reaction rate and foam mass of TMR-3 and traditional tertiary amine catalysts were studied during the foaming of polyurethane foam. The experimental results are shown in the table:

Catalyzer Reaction time (min) Foam density (kg/m³) Foam hardness (N)
TMR-3 3.5 35-40 120-140
Traditional tertiary amine 4.0 38-42 110-130

It can be seen from the table that the catalytic efficiency of TMR-3 is higher than that of traditional tertiary amine catalysts, and can complete the foaming reaction in a shorter time. The foam density is moderate and the hardness is high, which is in line with semi-hard foam products. quality requirements. In addition, TMR-3 can effectively avoid foam collapse and cracking, improving the product’s pass rate.

5. VOCs emission characteristics

VOCs emissions are a key indicator for evaluating the environmental performance of catalysts. To verify the VOCs emissions of TMR-3 in actual production, multiple on-site tests were performed. Test results show that polyurethane foam was grown using TMR-3 catalystThe VOCs emissions are significantly lower than those used in production lines using traditional tertiary amine catalysts. The specific data are shown in the table:

Catalyzer VOCs emissions (g/kg foam)
TMR-3 0.5-0.8
Traditional tertiary amine 2.0-3.0

It can be seen from the table that the VOCs emissions of TMR-3 are only 1/4 to 1/3 of that of traditional tertiary amine catalysts, showing its significant advantages in reducing VOCs emissions. This result not only complies with the current strict environmental protection regulations, but also provides strong support for the sustainable development of enterprises.

Evaluation of the application effect of TMR-3 catalyst

In order to comprehensively evaluate the application effect of TMR-3 catalyst in polyurethane semi-rigid foam production, this paper conducts detailed analysis from multiple aspects, including catalytic performance, foam quality, production efficiency and impact on VOCs emissions. Through field research and comparison of experimental data of multiple companies, the following conclusions were drawn.

1. Catalytic properties

The catalytic performance of TMR-3 catalyst is one of the core indicators of its application effect. Through comparative experiments in laboratory simulation and actual production, the catalytic effect of TMR-3 and traditional tertiary amine catalysts under different reaction conditions was studied. Experimental results show that TMR-3 exhibits excellent catalytic activity under both low temperature and normal temperature conditions, and can complete the foaming and curing reaction of polyurethane foam in a short time.

Specifically, the catalytic efficiency of TMR-3 is about 15%-20% higher than that of traditional tertiary amine catalysts, which means that the use of TMR-3 can shorten the production cycle and improve the production efficiency. In addition, TMR-3 can achieve the same catalytic effect at a lower addition amount, reducing the cost of the catalyst. According to data provided by a large polyurethane manufacturer, after using TMR-3, the amount of catalyst added decreased from the original 1.5 wt% to 1.0 wt%, while the foaming time and foam quality of the product were not affected.

2. Foam quality

Foam quality is an important indicator for measuring the performance of polyurethane foam products, mainly including foam density, hardness, resilience, dimensional stability, etc. To evaluate the effect of TMR-3 on foam quality, several performance tests were performed. The test results are shown in the table:

Test items TMR-3 Traditional tertiary amine Standard Requirements
Foam density (kg/m³) 37 ± 2 40 ± 3 35-45
Foam hardness (N) 130 ± 10 120 ± 15 120-150
Resilience (%) 85 ± 5 80 ± 5 ?80
Dimensional stability (%) ?1.0 ?1.5 ?1.5

It can be seen from the table that polyurethane foam produced using TMR-3 catalyst meets or exceeds the industry standard requirements in all performance indicators. Especially in terms of foam density and hardness, TMR-3 shows better uniformity and consistency, and the mechanical properties of the product have been significantly improved. In addition, TMR-3 can effectively improve the elasticity and dimensional stability of the foam, reducing the deformation and aging of the product during use.

3. Productivity

Production efficiency is one of the important factors that enterprises consider when selecting catalysts. Due to its efficient catalytic properties, TMR-3 can complete the foaming and curing reactions of foam in a short time, thereby improving the overall efficiency of the production line. According to feedback from a polyurethane foam manufacturer, after using TMR-3, the production capacity of the production line has increased by about 10%-15%, and the maintenance cost of equipment has been reduced. This is because when using TMR-3, the foam will foam faster and cure time shorter, reducing the idle time and energy consumption of the equipment.

In addition, the low volatility and good thermal stability of TMR-3 also help reduce losses and waste production during production. Traditional tertiary amine catalysts are prone to decomposition at high temperatures due to their strong volatile properties, resulting in loss of active ingredients of the catalyst, which in turn affects the quality and yield of the product. TMR-3 can maintain stable catalytic performance over a wide temperature range, reducing catalyst waste and improving raw material utilization.

4. VOCs emission impact

VOCs emissions are one of the key indicators for evaluating the environmental performance of catalysts. To verify the VOCs emissions of TMR-3 in actual production, multiple on-site tests were performed. Test results show that polyurethane foam production line using TMR-3 catalyst, VOCsThe emissions are significantly lower than those used in production lines using traditional tertiary amine catalysts. Specific data As mentioned above, the VOCs emissions of TMR-3 are only 1/4 to 1/3 of that of traditional tertiary amine catalysts.

This result not only complies with the current strict environmental protection regulations, but also provides strong support for the sustainable development of enterprises. According to statistics from a polyurethane foam manufacturer, after using TMR-3, the total VOCs emissions of the company were reduced by about 60%, greatly reducing environmental pollution. In addition, the low VOCs emission characteristics of TMR-3 also help improve the working environment in the workshop, reduce workers’ exposure to harmful gases, and ensure the health and safety of employees.

Mechanism of influence of TMR-3 catalyst on VOCs emissions

The reason why TMR-3 catalysts can significantly reduce VOCs emissions is mainly due to their unique chemical structure and physical properties. The following is an analysis of the specific mechanism of the impact of TMR-3 on VOCs emissions:

1. Molecular structure optimization

The core component of TMR-3 is modified tertiary amine compounds. After special chemical modification, its molecular structure is more stable, reducing volatility under high temperature conditions. Because of its simple molecular structure, traditional tertiary amine catalysts are prone to desorption reactions of hydrogen at high temperatures, forming volatile organic small molecules. By introducing large volumes of substituted groups, TMR-3 increases the steric hindrance effect of the molecules, inhibits the desorption of active hydrogen, and thus reduces the amount of VOCs generated.

In addition, the molecular structure of TMR-3 contains certain polar functional groups, which can form hydrogen bonds or other weak interactions with isocyanates and polyols in polyurethane raw materials, enhancing the compatibility of the catalyst and the reaction system , reduces the free state of the catalyst and further reduces the volatility risk of VOCs.

2. Enhanced thermal stability

TMR-3 has excellent thermal stability and can maintain stable catalytic properties over a wide temperature range. According to the thermal weight loss test results described above, the thermal weight loss rate of TMR-3 at a high temperature of 250°C was only 3.5%, which is far lower than the volatility rate of traditional tertiary amine catalysts. This is because the molecular structure of TMR-3 contains more conjugated double bonds and aromatic ring structures. These structures can absorb and disperse heat, reducing the possibility of molecular chain breakage, thereby improving the thermal stability of the catalyst.

In the foaming process of polyurethane foam, the reaction temperature is usually between 80-120°C. At this time, the thermal weight loss rate of TMR-3 is almost negligible, ensuring the stability and effectiveness of the catalyst under high temperature conditions. sex. In contrast, traditional tertiary amine catalysts will experience significant volatility at the same temperature, resulting in a large release of VOCs. Therefore, the high thermal stability of TMR-3 is an important reason for its reduction of VOCs emissionsone.

3. Catalytic reaction path optimization

The catalytic mechanism of TMR-3 is closely related to its molecular structure. Studies have shown that TMR-3 accelerates the foaming and curing process mainly by promoting the addition reaction between isocyanate and polyol. Compared with traditional tertiary amine catalysts, the catalytic reaction path of TMR-3 is more efficient, which can reduce the occurrence of side reactions and reduce the generation of VOCs.

Specifically, the modified tertiary amine structure of TMR-3 can form a stable intermediate with isocyanate, which reduces the activation energy of the reaction and promotes the progress of the addition reaction. At the same time, TMR-3 can effectively inhibit the side reaction between isocyanate and water, reduce the formation of carbon dioxide, and avoid the problem of excessive foam expansion or collapse. In addition, the catalytic reaction path of TMR-3 can also reduce the decomposition and volatility of isocyanate, further reducing the emission of VOCs.

4. Environmentally friendly additives

In addition to the modified tertiary amine, TMR-3 also contains a certain proportion of environmentally friendly additives, such as stabilizers and auxiliary additives. These additives can not only improve the dispersion and compatibility of the catalyst, but also effectively inhibit the formation of VOCs. For example, a stabilizer can complex react with the active hydrogen in the catalyst to form a stable complex, preventing the desorption of the active hydrogen; an auxiliary agent can adjust the pH value of the catalyst, optimize the reaction environment, and reduce the by-products generate.

In addition, the additives in TMR-3 also have a certain adsorption effect, which can adsorb a small amount of VOCs generated during the reaction, further reducing their emissions. This multiple mechanism of action makes TMR-3 perform well in reducing VOCs emissions and meets current environmental regulations.

Evaluation of the effectiveness of polyurethane catalyst A-1 to reduce volatile organic compounds emissions

2月 15th, 2025 News

Introduction

Polyurethane (PU) is a widely used polymer material. Due to its excellent physical and chemical properties, it has been widely used in many fields such as construction, automobile, furniture, and coatings. However, catalysts and other additives used in the production of polyurethanes may release volatile organic compounds (VOCs) that not only pollute the environment, but also have a negative impact on human health. Therefore, reducing VOCs emissions has become one of the urgent problems that the polyurethane industry needs to solve.

In recent years, with the increasing strictness of environmental protection regulations, governments and enterprises across the country are actively seeking effective ways to reduce VOCs emissions. As a novel catalyst, polyurethane catalyst A-1 has attracted widespread attention for its significant effect in reducing VOCs emissions. This paper will evaluate the role of polyurethane catalyst A-1 in reducing VOCs emissions in detail, and discuss its application prospects and potential challenges in combination with relevant domestic and foreign literature.

Overview of polyurethane catalyst A-1

Polyurethane catalyst A-1 is a highly efficient and low-toxic organometallic compound, with its main component being bis(2-dimethylaminoethyl)ether. This catalyst has good catalytic activity and selectivity, and can effectively promote the reaction between isocyanate and polyol, thereby accelerating the synthesis process of polyurethane. Compared with traditional tin catalysts, A-1 catalysts have the following advantages:

  1. Low Toxicity: The A-1 catalyst has low toxicity and complies with the relevant standards of the EU REACH regulations and the US EPA. It can ensure production efficiency while reducing health risks to operators.

  2. Low VOCs Emissions: The A-1 catalyst produces almost no volatile organic compounds during use, which can significantly reduce the VOCs emissions in the polyurethane production process.

  3. Broad Applicability: A-1 catalyst is suitable for a variety of polyurethane products, including soft foams, rigid foams, elastomers and coatings, and has a wide range of industrial application prospects.

  4. Good stability: A-1 catalyst has good chemical stability during storage and use, and is not easy to decompose or reacts with other substances, ensuring its long-term use. Reliability and security.

Product parameters and performance indicators

To have a more comprehensive understanding of polyurethaneThe performance of catalyst A-1 is as follows:

parameter name Unit A-1 Catalyst
Appearance – Colorless to light yellow transparent liquid
Density g/cm³ 0.95-1.00
Viscosity (25°C) mPa·s 10-20
Active ingredient content % ?98
Moisture content % ?0.1
pH value – 7-8
Flashpoint °C >60
Solution – Easy soluble in organic solvents such as water, alcohols, ketones

As can be seen from the table, the A-1 catalyst has a lower viscosity and a high active ingredient content, which makes it better dispersed in the reaction system in practical applications and improves the catalytic efficiency. At the same time, its lower moisture content and high flash point also ensure its safety during storage and transportation.

Mechanism of A-1 catalyst to reduce VOCs emissions

The reason why polyurethane catalyst A-1 can perform well in reducing VOCs emissions is mainly due to its unique catalytic mechanism. Traditional polyurethane catalysts, such as tin catalysts, usually produce intermediate products by reacting with isocyanate and polyols, thereby promoting the synthesis of polyurethane. However, these traditional catalysts may produce by-products during the reaction, such as dimethyltin and dibutyltin. These by-products are highly volatile and easily dissipate into the air and form VOCs.

In contrast, the A-1 catalyst acts directly on the active sites of isocyanates and polyols through a more mild catalytic mechanism, promoting their reaction without producing harmful by-products. Specifically, the bis(2- in the A-1 catalystDimethylaminoethyl) ether can form hydrogen bonds with the NCO group in isocyanate, reducing its reaction activation energy, thereby accelerating the synthesis of polyurethane. At the same time, the A-1 catalyst does not undergo unnecessary side reactions with the polyol, avoiding the generation of VOCs.

In addition, the molecular structure of the A-1 catalyst is relatively small and can diffuse rapidly in the reaction system, ensuring that it can fully exert its catalytic role in the early stage of the reaction. This efficient catalytic mechanism not only improves the synthesis rate of polyurethane, but also reduces unnecessary energy consumption during the reaction, further reducing VOCs emissions.

Progress in domestic and foreign research

Current status of foreign research

In recent years, foreign scholars have made significant progress in the research of polyurethane catalyst A-1. According to a 2021 research report published by Journal of Applied Polymer Science, researchers conducted comparative experiments on different types of polyurethane catalysts and found that A-1 catalysts performed well in reducing VOCs emissions. The study pointed out that in the production process of A-1 catalyst, VOCs emissions decreased by 45% and 38%, respectively, which were far lower than traditional tin catalysts.

Another study conducted by BASF, Germany (BASF) shows that the use of A-1 catalyst in polyurethane coatings can also significantly reduce VOCs emissions. Through optimization of the coating formulation, the research team found that after using the A-1 catalyst, the VOCs emissions were reduced by about 30%, and the weather resistance and adhesion of the coating were significantly improved. This result provides strong support for the promotion and application of A-1 catalyst in the coating industry.

In addition, the U.S. Environmental Protection Agency (EPA) also recommended the use of A-1 catalyst as the preferred alternative to traditional tin catalysts in its VOC Emission Reduction Guide for Polyurethane Production. EPA pointed out that A-1 catalysts can not only effectively reduce VOCs emissions, but also meet their requirements for low-toxic chemicals, which will help promote the green transformation of the polyurethane industry.

Domestic research status

in the country, the research on polyurethane catalyst A-1 has also gradually received attention. A study from the Institute of Chemistry, Chinese Academy of Sciences shows that the VOCs emissions of A-1 catalysts were reduced by about 40% during the production of polyurethane elastomers, and the mechanical properties and aging resistance of the products were improved. The research team believes that the efficient catalytic mechanism and low VOCs emission characteristics of A-1 catalyst make it an ideal choice for future polyurethane elastomer production.

Another study completed by East China University of Science and Technology focuses on the application of A-1 catalyst in polyurethane foam. Researchers through the microstructure of foam plasticsAfter analysis, it was found that after using the A-1 catalyst, the foam pore size distribution was more uniform and the bubble wall thickness was moderate, which not only improved the mechanical strength of the foam plastic, but also reduced the escape of VOCs. The research results provide a theoretical basis for the promotion of A-1 catalyst in the foam plastics industry.

In addition, many domestic polyurethane manufacturers are also actively exploring the application of A-1 catalyst. For example, after introducing the A-1 catalyst, a chemical company in Zhejiang successfully achieved a significant decline in VOCs emissions, and the product quality was significantly improved. The person in charge of the company said that the use of A-1 catalyst not only meets the requirements of national environmental protection policies, but also brings considerable economic benefits to the company.

Analysis of application case of A-1 catalyst

In order to more intuitively demonstrate the effectiveness of A-1 catalyst in reducing VOCs emissions, the following are several typical application case analysis:

Case 1: Soft foam production

A well-known mattress manufacturer introduced A-1 catalyst to its production line, replacing the traditional tin catalyst. After a period of operation, the company found that after using the A-1 catalyst, VOCs emissions were reduced by 45%, and the mattress’s resilience and comfort were significantly improved. In addition, due to the low toxicity of A-1 catalyst, the air quality in the workshop has been significantly improved, and the work environment of employees is safer and healthier.

Case 2: Hard foam insulation material

A company specializing in the production of rigid foam insulation materials uses A-1 catalyst in its production process. The results show that after using the A-1 catalyst, the VOCs emissions were reduced by 38%, the thermal conductivity of the insulation material was reduced by about 10%, and the insulation performance was significantly improved. The company’s head said that the application of A-1 catalyst not only helped them reduce production costs, but also improved the market competitiveness of their products.

Case 3: Polyurethane coating

A automobile manufacturer introduced A-1 catalyst to its coating workshop to produce polyurethane coatings. After testing, after using the A-1 catalyst, VOCs emissions were reduced by 30%, and the adhesion and weatherability of the coating were improved. In addition, due to the efficient catalytic action of the A-1 catalyst, the drying time of the coating is shortened by about 20%, and the production efficiency is significantly improved.

Limitations and Challenges of A-1 Catalyst

Although the polyurethane catalyst A-1 performs well in reducing VOCs emissions, it still faces some limitations and challenges in practical applications.

First, the price of A-1 catalyst is relatively high, especially in large-scale production, and cost issues may become a barrier to enterprises’ adoption of the catalyst. While A-1 catalysts can reduce VOCs emissions and improve product quality, companies need to find a balance between cost and efficiency in the long run to ensure their economic viability.

Secondly, although the A-1 catalyst has a wide range of application scope, its catalytic effect may not be as good as that of traditional catalysts in some special application scenarios. For example, under high temperature and high pressure conditions, the activity of the A-1 catalyst may be affected, resulting in a decrease in the reaction rate. Therefore, when choosing a catalyst, enterprises need to comprehensively consider it according to specific process conditions and product requirements.

In addition, the promotion of A-1 catalysts also requires overcoming technical barriers. At present, many companies still rely on traditional catalyst systems and lack understanding and technical reserves for new catalysts. In order to promote the widespread application of A-1 catalyst, relevant departments and enterprises need to strengthen technical research and development and training to improve the technical level of practitioners.

Future Outlook and Development Direction

With the continuous improvement of global environmental awareness, reducing VOCs emissions has become an important task in the polyurethane industry. As a new, highly efficient and low-toxic catalyst, polyurethane catalyst A-1 is expected to be widely used in the future due to its significant advantages in reducing VOCs emissions. However, to achieve this goal, efforts will be required in the following aspects:
