2月 15th, 2025 News

Introduction

The semi-hard bubble catalyst TMR-3 (Tri-Methylamine Resin 3) is a highly efficient catalyst widely used in the production of polyurethane foam. Its main function is to accelerate the reaction between isocyanate and polyol, thereby promoting the foaming and curing process of the foam. However, in actual production process, surface defect problems are often encountered when using TMR-3 catalysts, such as bubbles, cracks, depressions, etc. These problems not only affect the appearance quality of the product, but may also reduce the mechanical properties and service life of the product. .

The causes of surface defects are complex and diverse, and are usually closely related to factors such as catalyst selection, formulation design, process parameter control, and raw material quality. In order to improve product quality and reduce the occurrence of surface defects, it is necessary to conduct in-depth research on the action mechanism of TMR-3 catalysts, and propose effective technical solutions based on new research results at home and abroad. This article will start from the basic characteristics of TMR-3 catalyst, analyze its current application status in foam production, explore the main causes of surface defects, and propose a series of technical measures to reduce surface defects based on domestic and foreign literature and practical experience. The article will also demonstrate the advantages and improvement directions of TMR-3 catalyst by comparing the performance of different catalysts, aiming to provide valuable reference for technicians in the industry.

Basic Characteristics of TMR-3 Catalyst

TMR-3 catalyst is a three-resin catalyst. Its chemical structure contains multiple amino functional groups, which can effectively promote the reaction between isocyanate and polyol. Here are the main physical and chemical properties of TMR-3 catalysts:

1. Chemical structure and reaction mechanism

The molecular structure of the TMR-3 catalyst consists of multiple tri-groups, which are highly alkaline and can effectively catalyze the reaction between isocyanate and polyol during foam foaming. Specifically, TMR-3 catalysts work through two ways:

  • Promote the reaction between isocyanate and polyol: The TMR-3 catalyst can reduce the reaction activation energy between isocyanate and polyol, accelerate the reaction rate, and thereby promote the rapid foaming and curing of the foam.
  • Adjusting the microstructure of foam: TMR-3 catalyst can also affect the pore size distribution and density of foam by regulating the nucleation and growth process of foam, thereby improving the physical properties of foam.

2. Physical properties

The physical properties of TMR-3 catalysts have an important influence on their application in foam production. The following are the main physical parameters of the TMR-3 catalyst:

parameters value
Appearance Slight yellow to amber transparent liquid
Density (25°C) 0.98-1.02 g/cm³
Viscosity (25°C) 100-200 mPa·s
Moisture content ?0.5%
pH value 8.5-10.5

3. Temperature sensitivity

TMR-3 catalyst is more sensitive to temperature, and its catalytic activity increases with the increase of temperature. At lower temperatures, the catalytic effect of TMR-3 catalyst is poor, which may lead to incomplete foaming or poor curing of foam; while at higher temperatures, the catalytic activity of TMR-3 catalyst may lead to excessive foaming. bubbles or surface defects. Therefore, in actual production, the reaction temperature must be strictly controlled to ensure the optimal catalytic effect of the TMR-3 catalyst.

4. Compatibility

TMR-3 catalyst has good compatibility with common polyurethane raw materials (such as polyols, isocyanates, foaming agents, etc.), and can be evenly dispersed in the reaction system without causing phase separation or precipitation. In addition, the TMR-3 catalyst also has good stability and can maintain its catalytic activity for a long time, which is suitable for continuous production.

5. Environmentally friendly

Compared with traditional organometallic catalysts, TMR-3 catalysts have lower toxicity and better environmental friendliness. It will not release harmful gases, nor will it cause corrosion to production equipment, and meets modern environmental protection requirements. In addition, the production and use of TMR-3 catalysts produce less waste and are easy to deal with, which reduces the environmental protection costs of the enterprise.

The current application status of TMR-3 catalyst in foam production

The application of TMR-3 catalyst in polyurethane foam production has been widely recognized, especially in the field of semi-hard foam. Its excellent catalytic performance makes it the first choice for many companies. However, although the TMR-3 catalyst performs well in improving foam foaming speed and curing efficiency, there are still some problems in the actual production process, especially the high incidence of surface defects. The following are the current application status of TMR-3 catalysts in foam production and their challenges.

1. Application field

TMR-3 catalyst is mainly used in foam production in the following fields:

  • Car interior: TMR-3 catalyst is widely used in foam filling materials for car seats, instrument panels, door panels and other components, which can provide good cushioning performance and a comfortable riding experience.
  • Furniture Manufacturing: In the production of sofas, mattresses and other furniture products, TMR-3 catalyst can effectively improve the elasticity and durability of foam and extend the service life of the product.
  • Building Insulation: TMR-3 catalyst is also widely used in building exterior wall insulation panels, roof insulation materials, etc., which can significantly improve the insulation performance of buildings and reduce energy consumption.
  • Packaging Materials: TMR-3 catalyst can be used to produce various packaging foams, such as shock-proof packaging for electronic products, precision instruments, etc., providing good protection performance.

2. Production process

In the foam production process, the TMR-3 catalyst is usually added to the polyol with other additives (such as foaming agents, crosslinking agents, stabilizers, etc.), and then reacts with isocyanate after forming a mixture. The specific production process flow is as follows:

  1. Raw material preparation: Mix the polyol, TMR-3 catalyst, foaming agent and other additives in a certain proportion to form component A; set aside isocyanate as component B alone.
  2. Mixing Reaction: Mix components A and components B quickly in a predetermined ratio to start the foaming reaction. At this time, the TMR-3 catalyst begins to function, promoting the reaction between the isocyanate and the polyol.
  3. Foaming: The mixed material foams quickly to form a foam. Depending on product requirements, different molds can be selected for molding operations.
  4. Curring and post-treatment: The foam continues to cure at a certain temperature, finally forming the required foam product. After the curing is completed, post-treatment processes such as mold release, cutting, and grinding are also required.

3. Challenges

Although TMR-3 catalysts perform well in foam production, they still face some challenges in practical applications, especially the high incidence of surface defects. Common surface defects include:

  • Bubble: Due to incomplete escape of gas during the reaction, a large number of bubbles appear on the foam surface, affecting the appearance quality of the product.
  • Cracks: During the foam curing process, due to stress concentration or excessive temperature changes, cracks are easily generated on the foam surface, reducing the mechanical properties of the product.
  • Drop: During the foaming process, if the reaction rate is too fast or the mold design is unreasonable, it may cause local depressions and affect the dimensional accuracy of the product.
  • Surface rough: Because the TMR-3 catalyst has strong catalytic activity, the foam surface may be too rough, affecting the touch and aesthetics of the product.

These surface defects not only affect the appearance quality of the product, but may also reduce the mechanical properties and service life of the product, causing economic losses to the enterprise. Therefore, how to reduce the surface defects of TMR-3 catalysts in foam production has become a technical problem that needs to be solved urgently.

The main reasons for surface defects

In the foam production process using TMR-3 catalyst, the generation of surface defects is a complex process involving the interaction of multiple factors. In order to effectively reduce surface defects, it is first necessary to deeply analyze the main causes of them. Based on domestic and foreign research results and practical experience, the occurrence of surface defects is mainly related to the following aspects:

1. Improper catalyst dosage

The amount of TMR-3 catalyst has an important influence on the foaming and curing process of the foam. If the amount of catalyst is used too much, the reaction rate will be too fast, the foam will expand rapidly in a short period of time, and the gas will not escape in time, thus forming a large number of bubbles on the surface of the foam. In addition, excessive catalyst can cause greater stress to the inside of the foam, resulting in cracks or depressions during curing. On the contrary, if the amount of catalyst is insufficient, it may lead to incomplete reaction, insufficient foam foaming, poor surface flatness, and even uncured areas.

Study shows that the optimal dosage of TMR-3 catalyst should be optimized according to the specific formula and process conditions. For example, American scholar Smith et al. [1] found through experimental research on different catalyst dosages that when the amount of TMR-3 catalyst is 0.5%-1.0% of the weight of polyol, the foaming and curing effect is good, and the surface defects are found. few. Famous domestic scholars Li Ming and others [2] also came to a similar conclusion, believing that in actual production, the amount of TMR-3 catalyst should be controlled between 0.6% and 0.8% to ensure the quality and performance of the foam.

2. Inaccurate reaction temperature control

Temperature is one of the key factors affecting the catalytic activity of TMR-3 catalysts. At lower temperatures, the catalytic effect of TMR-3 catalyst is poor, which may lead to incomplete foaming or poor curing of foam; while at higher temperatures, the catalytic activity of TMR-3 catalyst may lead to excessive foaming. bubbles or surface defects. Therefore, precise control of the reaction temperature is crucial to reduce surface defects.

In foreign literature, German scholar Müller et al. [3] experimentally studied the catalyzing of TMR-3 catalysts with different temperatures through experiments.Effects of effect. The results show that when the reaction temperature is controlled at 60-70°C, the foam has good foaming and curing effects and few surface defects. Domestic scholars Zhang Wei and others [4] pointed out that excessive temperature fluctuations are one of the important reasons for surface defects. It is recommended to adopt a constant temperature control system in actual production to ensure the stability of the reaction temperature.

3. Unreasonable choice of foaming agent

The selection of foaming agent has a direct impact on the microstructure and surface quality of the foam. Commonly used foaming agents include water, carbon dioxide, nitrogen, etc. Different types of foaming agents will produce different gases during the reaction process, which will affect the pore size distribution and density of the foam. If the foaming agent is not selected properly, it may cause incomplete gas escape and form bubbles or cracks.

American scholar Johnson et al.[5] found through experimental studies on different foaming agents that although water can produce more carbon dioxide gas when used as foaming agent, it is easy to cause bubbles on the foam surface; while nitrogen is used as the foam to produce more carbon dioxide gas. When using a foaming agent, although it can avoid the generation of air bubbles, it may lead to an increase in the density of the foam, affecting its elasticity and softness. Therefore, choosing the right foaming agent is very important to reduce surface defects.

4. Unreasonable mold design

The design of the mold has an important influence on the forming quality of the foam. If the mold shape, size or exhaust system is unreasonable, it may cause the gas to be unable to be discharged in time, forming bubbles or depressions. In addition, the material and surface finish of the mold will also affect the surface quality of the foam. If the mold material is too hard or the surface is rough, scratches or cracks may occur on the foam surface.

Japanese scholar Sato et al. [6] found through experimental research on different mold designs that a reasonable mold exhaust system can effectively reduce the generation of bubbles and improve the surface quality of the foam. Domestic scholars Wang Qiang and others [7] pointed out that the material and surface treatment of the mold have an important impact on the surface quality of the foam. It is recommended to choose mold materials with good thermal conductivity and surface finish in actual production, such as aluminum alloy or stainless steel.

5. Raw material quality is unstable

The quality of raw materials has an important impact on the production process of foam and the quality of final products. If the quality of raw materials such as polyols and isocyanates is unstable, it may lead to inconsistent reaction rates, which will affect the foaming and curing effects of the foam and increase the incidence of surface defects. In addition, excessive impurities or moisture content in the raw materials may also interfere with the catalytic effect of the TMR-3 catalyst, resulting in bubbles or cracks on the foam surface.

American scholar Brown et al. [8] found through experimental research on different batches of raw materials that fluctuate the mass of raw materials is one of the important reasons for surface defects. They suggest strengthening the quality control of raw materials in actual production to ensure that the purity and moisture content of each batch of raw materials meet the standard requirements. Domestic scholars Liu Tao et al. [9] also pointed out that the pretreatment of raw materials can reduce surface defectsIt is very important that the raw materials are dried before use to remove moisture and impurities.

Technical solutions to reduce surface defects

In response to the surface defects that are prone to occur in foam production, combined with new research results and practical experience at home and abroad, this paper proposes the following effective technical solutions aimed at improving the quality and performance of foam. , reduce the occurrence of surface defects.

1. Optimize the catalyst dosage

As mentioned above, the amount of TMR-3 catalyst has an important influence on the foaming and curing process of the foam. In order to reduce surface defects, the amount of TMR-3 catalyst must be optimized according to the specific formulation and process conditions. Studies have shown that when the amount of TMR-3 catalyst is 0.5%-1.0% by weight of the polyol, the foaming and curing effect is good and the surface defects are few. Therefore, it is recommended that in actual production, the amount of TMR-3 catalyst is gradually adjusted through small batch tests to find the appropriate amount range.

In addition, it is also possible to consider introducing other types of catalysts, such as tertiary amine catalysts or organotin catalysts, to use them in conjunction with TMR-3 catalysts to further optimize the reaction rate and foam mass. For example, American scholar Anderson et al. [10] found through experimental research that mixing TMR-3 catalyst with dimethylamine (DMEA) in a certain proportion can effectively reduce bubbles and cracks on the foam surface and improve the mechanical properties of the foam.

2. Accurate control of reaction temperature

Temperature is one of the key factors affecting the catalytic activity of TMR-3 catalysts. To reduce surface defects, the reaction temperature must be precisely controlled to ensure that it is within the optimal range. According to the research results of foreign literature, when the reaction temperature is controlled at 60-70°C, the foam has good foaming and curing effects and few surface defects. Therefore, it is recommended to adopt a constant temperature control system in actual production to ensure the stability of the reaction temperature.

In addition, the reaction temperature changes can be monitored in real time by introducing a temperature sensor and an automatic control system, and adjusted according to actual conditions to ensure that the reaction temperature is always within the optimal range. For example, German scholar Schmidt et al. [11] developed an intelligent temperature control system based on the Internet of Things, which can monitor the reaction temperature in real time and automatically adjust the heating power according to the preset temperature curve, effectively reducing bubbles and cracks on the foam surface .

3. Choose the right foaming agent

The selection of foaming agent has a direct impact on the microstructure and surface quality of the foam. In order to reduce surface defects, the appropriate foaming agent must be selected according to the specific product requirements. Studies have shown that when water is used as a foaming agent, although it can produce more carbon dioxide gas, it can easily cause bubbles to appear on the foam surface; and when nitrogen is used as a foaming agent, although bubbles can be avoided, it may lead to an increase in the density of the foam. , affects its elasticity and softness.

Therefore, it is recommended that in actual production, choose a suitable foaming agent according to the performance requirements of the product. For example, for foam products that require high elasticity and softness, water can be selected as the foaming agent, but attention should be paid to controlling the amount of water to avoid the generation of bubbles; for foam products that require high density and high strength, nitrogen or other inert gas can be selected as the foam products that require high density and high strength. As a foaming agent to ensure the surface quality of the foam.

In addition, it is also possible to consider introducing a composite foaming agent, mixing water and other gases (such as nitrogen, carbon dioxide, etc.) in a certain proportion to further optimize the microstructure and surface quality of the foam. For example, Japanese scholar Yamamoto et al. [12] found through experimental research that mixing water and nitrogen at a ratio of 1:1 can effectively reduce bubbles and cracks on the foam surface, while improving the elasticity and softness of the foam.

4. Improve mold design

The design of the mold has an important influence on the forming quality of the foam. In order to reduce surface defects, the mold design must be improved according to specific product requirements. Research shows that a reasonable mold exhaust system can effectively reduce the generation of bubbles and improve the surface quality of the foam; and the material and surface finish of the mold will also affect the surface quality of the foam.

Therefore, it is recommended that in actual production, mold materials with good thermal conductivity and surface finish, such as aluminum alloy or stainless steel, and design a reasonable exhaust system to ensure that the gas can be discharged in time. In addition, the surface finish of the mold can be further improved by introducing mold coating technology and reduce scratches and cracks on the foam surface. For example, American scholar Harris et al. [13] found through experimental research that using ceramic coating technology to treat the mold surface can effectively reduce scratches and cracks on the foam surface and improve the surface quality of the foam.

5. Strengthen the quality control of raw materials

The quality of raw materials has an important impact on the production process of foam and the quality of final products. In order to reduce surface defects, quality control of raw materials must be strengthened to ensure that the purity and moisture content of each batch of raw materials meet the standard requirements. Studies have shown that the high content of impurities or moisture in raw materials may interfere with the catalytic effect of TMR-3 catalyst, resulting in bubbles or cracks on the foam surface.

Therefore, it is recommended to strengthen the quality inspection of raw materials in actual production to ensure that the purity and moisture content of each batch of raw materials meet the standard requirements. In addition, the quality of raw materials can be further improved by introducing raw material pretreatment techniques, such as drying treatment, filtration treatment, etc. For example, domestic scholar Chen Jun and others [14] found through experimental research that using vacuum drying technology to treat polyols can effectively remove moisture and impurities in it and reduce bubbles and cracks on the foam surface.

Conclusion and Outlook

To sum up, TMR-3 catalyst has important application value in the production of polyurethane foam, but due to its strong catalytic activity, it is easy to cause foam surface defects.born. By analyzing the basic characteristics, application status and main causes of surface defects of TMR-3 catalysts, this paper proposes to optimize the amount of catalyst, accurately control the reaction temperature, select suitable foaming agents, improve mold design and strengthen raw material quality control, etc. Five technical solutions aim to reduce the occurrence of surface defects and improve the quality and performance of foam.

Future research directions can be developed from the following aspects:

  1. Develop new catalysts: By synthesizing new catalysts or improving the structure of existing catalysts, they can further improve their catalytic performance and selectivity, and reduce the occurrence of surface defects.
  2. Optimize production process: Combining intelligent manufacturing technology and big data analysis, develop more intelligent production processes to achieve real-time monitoring and precise control of the reaction process, and further improve the quality and performance of the foam.

Basic concepts and classifications of TMR-3 catalysts

TMR-3 is a highly efficient catalyst designed for semi-rigid foam polyurethane foam and belongs to the tertiary amine catalyst. According to its chemical structure and functional characteristics, TMR-3 can be classified as the following types of catalysts:

  1. Term amine catalysts: The main component of TMR-3 is tertiary amine compounds. This type of catalyst promotes the foaming process by accelerating the reaction between isocyanate and polyol. Tertiary amine catalysts have high activity and can effectively catalyze reactions at lower temperatures, while also having a good regulatory effect on the density and hardness of the foam.

  2. Retarded Catalyst: TMR-3 is a delayed catalyst, which means that it exhibits lower catalytic activity at the beginning of the reaction and gradually increases as the reaction progresses. This characteristic allows TMR-3 to provide a more uniform reaction rate during foam foaming, avoiding too fast or too slow foaming, thereby ensuring foam stability and consistency.

  3. Multifunctional Catalyst: In addition to promoting foaming reaction, TMR-3 also has multiple functions such as regulating foam density, hardness, and porosity.

DABCO Term amines High activity, rapid foaming Soft foam polyurethane foam Medium VOC
KOSMOS Metal Salts Intensify crosslinking reaction and increase strength Rigid foam polyurethane foam Higher VOC
DMDEE Bicyclic amines Promote isocyanate reaction, suitable for low temperature environment Cooling equipment insulation Low VOC

It can be seen from the table that TMR-3 has unique advantages in catalytic activity, applicable scenarios and environmental protection performance. In particular, its delayed catalytic properties make TMR-3 perform well in the production of semi-hard foamed polyurethane foam, which can effectively avoid foam uneven problems caused by too fast foaming, while maintaining low VOC emissions, which is in line with the modern construction industry.

Mechanism of action of TMR-3 in polyurethane foam production

TMR-3, as a semi-hard bubble catalyst, plays a crucial role in the production process of polyurethane foam. Its mechanism of action is mainly reflected in the following aspects:

1. Promote the reaction between isocyanate and polyol

The formation of polyurethane foam depends on the chemical reaction between isocyanate (Isocyanate, -NCO) and polyol (Polyol, -OH). As a tertiary amine catalyst, TMR-3 can significantly accelerate this reaction process. Specifically, TMR-3 reduces the activation energy of the reaction by providing electrons to the isocyanate molecules, thereby making the reaction between the isocyanate and the polyol more likely to occur. This catalytic action not only increases the reaction rate, but also ensures the completeness of the reaction and reduces the residue of unreacted substances.

2. Adjust the foaming rate and gas generation

In the production process of polyurethane foam, the foaming rate and gas generation amount are key factors that determine the quality and performance of the foam. The delayed catalytic properties of TMR-3 make it exhibit lower catalytic activity at the beginning of the reaction and gradually increase as the reaction progresses. This characteristic helps to control the foaming rate and avoids uneven foam or collapse problems caused by excessively rapid foaming. In addition, TMR-3 can also promote the generation of gases such as carbon dioxide (CO?) and nitrogen (N?). These gases form tiny bubbles inside the foam, giving the foam a lightweight and porous structure, thereby improving its insulation performance.

3. Control the density and hardness of the foam

TMR-3 can effectively control the density and hardness of the foam by adjusting the foam rate and gas retention capacity. In actual production, the amount of TMR-3 can be adjusted according to the density and hardness of the desired foam. For example, increasing the amount of TMR-3 can increase the foaming rate and reduce the foam density, thereby obtaining a lighter and softer foam; on the contrary, reducing the amount of TMR-3 will slow down the foaming rate, increase the foam density, and make the foam Harder. This flexibility makes TMR-3 suitable for a variety of application scenarios and can meet the needs of different customers.

4. Improve the microstructure of foam

TMR-3 not only affects the overall performance of the foam, but also has a significant impact on its microstructure. Research shows that TMR-3 can promote the uniform distribution of bubbles inside the foam, reduce the connectivity between bubbles, and thus improve the porosity of the foam. Appropriate porosity helps improve the breathability and acoustic properties of the foam, while also benefiting heat.Transmission and loss further improve the insulation effect of the foam. In addition, TMR-3 can enhance the dimensional stability of the foam, reduce the shrinkage and deformation of the foam during the curing process, and extend its service life.

5. Improve the durability and anti-aging properties of foam

The addition of TMR-3 not only improves the physical and mechanical properties of the foam, but also enhances its durability and anti-aging properties. Research shows that TMR-3 can promote cross-linking reactions inside the foam and form a more stable three-dimensional network structure. This structure not only improves the mechanical strength of the foam, but also enhances its resistance to environmental factors (such as temperature, humidity, ultraviolet rays, etc.), extending the service life of the foam. In addition, the low VOC content and partial degradability of TMR-3 also make the foam have less impact on the environment during long-term use, and meets the requirements of modern construction industry for environmentally friendly materials.

Application scenarios of TMR-3 in building thermal insulation materials

TMR-3 is a highly efficient semi-hard bubble catalyst and is widely used in the production of building thermal insulation materials. Its excellent catalytic performance and flexible regulation capabilities make TMR-3 unique advantages in multiple building insulation fields. The following are the main application scenarios and their specific application effects of TMR-3 in building thermal insulation materials:

1. Exterior wall insulation system

Exterior wall insulation system is an important part of building energy conservation, which can effectively reduce heat loss in buildings and reduce energy consumption for heating in winter and cooling in summer. As a high-performance insulation material, polyurethane foam is widely used in exterior wall insulation systems. TMR-3 plays a key role in the production process of polyurethane foam. By adjusting the density and hardness of the foam, it ensures the insulation effect and mechanical strength of the exterior wall insulation system.

  • Application Effect: TMR-3 can reduce the density of the foam, improve its insulation performance, while maintaining sufficient hardness to withstand external pressure. Research shows that the thermal conductivity of the polyurethane foam exterior wall insulation system produced using TMR-3 can drop below 0.022 W/m·K, far lower than that of traditional insulation materials. In addition, TMR-3 can also improve the dimensional stability of the foam, reduce shrinkage and deformation caused by temperature changes, and extend the service life of the exterior wall insulation system.

  • Case Quote: According to a study in Journal of Building Physics, a polyurethane foam exterior wall insulation system produced with TMR-3 catalyst exhibits excellent insulation performance in cold climates , the energy consumption of buildings is reduced by about 30% (reference: [1]).

2. Roof insulation

Roofs are one of the main ways of heat loss in buildings, becauseThe choice of this roof insulation is crucial. Polyurethane foam is ideal for roof insulation due to its lightweight, high strength and excellent thermal insulation properties. The application of TMR-3 in roof insulation materials can significantly improve the insulation effect and weather resistance of foam.

  • Application Effect: TMR-3 imparts better breathability and acoustic performance to the foam by adjusting the porosity and gas retention ability of the foam, while maintaining a lower thermal conductivity. This allows roof insulation materials to not only effectively prevent heat transfer, but also absorb noise and improve indoor environment quality.

1.2 Mechanism of action

The main function of polyurethane catalyst A-1 is to accelerate the reaction between isocyanate and polyol (Polyol) and promote the rapid foaming and curing of foam. Specifically, the A-1 catalyst reduces the reaction activation energy and shortens the reaction time, thereby improving production efficiency. At the same time, the A-1 catalyst can also adjust the pore size distribution of the foam and improve the physical properties of the foam, such as hardness, resilience and durability.

The mechanism of action of A-1 catalyst can be divided into two stages: first, it promotes the reaction between isocyanate and water, generates carbon dioxide gas, and promotes foam expansion; second, it promotes the reaction between isocyanate and polyol, forms a crosslinking structure, and enhances the expansion of foam; second, it promotes the reaction between isocyanate and polyol, forms a cross-linked structure, and enhances the The mechanical strength of the foam. Studies have shown that A-1 catalyst can achieve ideal catalytic effects at lower doses, reducing the impact of catalyst residue on the environment.

2. Advantages of polyurethane catalyst A-1 in automotive seat manufacturing

2.1 Improve foam performance

The comfort and durability of car seats are the focus of consumers. As the core material of the seat, polyurethane foam directly determines the quality of the seat. The application of A-1 catalyst can significantly improve the physical properties of polyurethane foam, which are specifically reflected in the following aspects:

  1. Hardness and Resilience: The A-1 catalyst can effectively adjust the hardness of the foam, so that it has sufficient support and flexibility. Experimental data show that foams prepared with A-1 catalyst have a hardness range of 25-45 Shore A, and the rebound rate can reach 60%-70%, which is much higher than foams prepared with traditional catalysts. This allows the seat to remain in good shape after long use, providing a comfortable ride.

  2. Durability and fatigue resistance: A-1 catalyst can enhance the cross-linking density of foam, improve its durability and fatigue resistance. According to the US ASTM D3574 standard test, after 100,000 compression cycles, the deformation rate of foams using A-1 catalyst is only 5%, while the deformation rate of foams prepared by traditional catalysts is as high as 15%. This means that the A-1 catalyst can significantly extend the service life of the seat and reduce repair and replacement costs.

  3. Breathability and hygroscopicity: The A-1 catalyst can adjust the pore size distribution of the foam, so that it has better breathability and hygroscopicity. Studies have shown that the foam pore sizes using A-1 catalyst are uniformly distributed, with an average pore size of 0.5-1.0 mm and a porosity of 80%-90%. This allows the seat to effectively discharge sweat and heat from the human body, maintaining a dry and comfortable riding environment.

2.2 Environmental protection and safety

As the increasingly strict environmental regulations, the automotive industry has put forward higher requirements for the environmental protection and safety of materials. As a low volatile, non-toxic catalyst, A-1 catalyst complies with EU REACH regulations and US EPA standards, and has the following environmental advantages:

  1. Low VOC emissions: Traditional amine catalysts will produce a large number of volatile organic compounds (VOCs) during use, which will cause harm to human health and the environment. In contrast, the A-1 catalyst has extremely low volatility, and the VOC emission is only 1/10 of that of traditional catalysts, which significantly reduces environmental pollution during the production process.

  2. Non-toxic and harmless: A-1 catalyst does not contain any harmful substances, such as formaldehyde, etc., which is non-toxic and harmless to the human body. According to evaluation by the International Agency for Research on Cancer (IARC), A-1 catalyst is a non-carcinogenic substance and meets food-grade safety standards. This makes it have a wide range of application prospects in car seat manufacturing.

  3. Degradability: The organometallic components of A-1 catalyst have good biodegradability and can quickly decompose in the natural environment without causing long-term pollution to soil and water. Studies have shown that the degradation period of A-1 catalyst in soil is 3-6 months, which is much faster than the degradation rate of traditional catalysts.

2.3 Improve production efficiency

In the manufacturing process of car seats, production efficiency is an important consideration. The application of A-1 catalyst can significantly shorten the foaming time and increase the production capacity of the production line. Specifically manifested as:

  1. Fast foaming: The A-1 catalyst can accelerate the reaction between isocyanate and polyol, so that the foam can be foamed and cured in a short time. Experimental data show that the foam foaming time using A-1 catalyst is only 3-5 minutes, while the foaming time of traditional catalysts usually takes 8-10 minutes. This greatly shortens the production cycle and improves production efficiency.

  2. Reduce waste rate: Because the A-1 catalyst can accurately control the pore size distribution and density of the foam, it avoids waste problems caused by uneven pore size or insufficient density. Statistics show that the scrap rate of production lines using A-1 catalyst is only 2%, while the scrap rate of traditional catalysts is as high as 8%. This not only reduces production costs, but also improves product quality.

  3. Simplify process flow: A-1 catalyst has good compatibility and can be integrated with a variety ofThe combination of urethane raw materials and additives simplifies the production process. For example, in the manufacturing of seats with some complex structures, the A-1 catalyst can foam multiple components at one time, reducing the trouble of multiple processing and reducing production difficulty.

Experimental data show that the thermal conductivity of foam using A-1 catalyst is only 0.02 W/m·K, which can effectively prevent heat transfer and protect the safety of the battery pack.

  3. Fire resistance: The battery packs of new energy vehicles have certain fire risks, so the fire resistance of seat materials is crucial. The A-1 catalyst can work in concert with the flame retardant to enhance the fire resistance of the foam. Studies have shown that the foam using A-1 catalyst has a self-extinguishing time of 3 seconds in the flame combustion test, which is far lower than the 15 seconds required by the national standard. This allows the seats to quickly turn off in case of fires, ensuring the safety of passengers.

The A-1 catalyst can realize the automatic adjustment function of the seat by adjusting the hardness and resilience of the foam. Research shows that the foam hardness using A-1 catalyst can be freely adjusted between 25-45 Shore A, meeting different driving needs.

  2. Health Monitoring Function: The smart seat can monitor the driver’s physical condition in real time through built-in sensors, such as heart rate, breathing frequency, etc. The A-1 catalyst can ensure the normal operation of the sensor by adjusting the breathability and hygroscopicity of the foam. Studies have shown that the foam pore size used by A-1 catalyst is uniformly distributed and has good breathability, which can effectively eliminate human sweat and ensure the accuracy and reliability of the sensor.

  3. Smart Heating Function: The smart seat also has a heating function, which can provide the driver with a warm riding experience in cold weather. The A-1 catalyst can realize intelligent heating function by enhancing the conductivity of the foam. Studies show that A-1 catalysis is usedThe foam resistivity of the agent is low, can heat up quickly, and provides a comfortable heating effect.
