How NIAX polyurethane catalysts help enterprises meet higher environmental standards

Introduction

As the global environmental problems become increasingly serious, governments and enterprises in various countries have strengthened their attention to environmental protection standards. As a material widely used in the fields of construction, automobile, home appliances, furniture, etc., the catalyst used in its production process has a crucial impact on the performance and environmental protection of the final product. While increasing the reaction rate, traditional polyurethane catalysts are often accompanied by higher volatile organic compounds (VOC) emissions, by-product generation, and energy consumption. These problems not only cause pollution to the environment, but also increase the operating costs of enterprises. .

Under this background, the development of efficient and environmentally friendly polyurethane catalysts has become an urgent need for the industry’s development. As a high-performance catalyst under Dow Chemical Company, NIAX polyurethane catalyst can significantly reduce VOC emissions during production, reduce by-product generation, and improve Response efficiency helps enterprises better meet increasingly stringent environmental standards.

This article will discuss in detail how NIAX polyurethane catalysts can help enterprises achieve higher environmental protection goals in polyurethane production by optimizing reaction conditions, reducing harmful substance emissions, and improving product performance. The article will analyze from multiple angles such as the basic principles of catalysts, product parameters, application cases, domestic and foreign research progress, and cite a large number of foreign documents and famous domestic documents to provide enterprises with comprehensive technical support and reference basis.

The basic principles of NIAX polyurethane catalyst

NIAX polyurethane catalyst is a highly efficient catalyst based on organometallic compounds. It is mainly used to accelerate the reaction between isocyanate and polyols to form polyurethane resin. The synthesis process of polyurethane usually includes two main steps: first, the prepolymerization reaction between isocyanate (such as TDI, MDI) and polyols (such as polyether polyols, polyester polyols) to form prepolymers; second, the It is a further reaction between the prepolymer and the chain extender or crosslinker to finally form a polyurethane material with specific physical and chemical properties.

1. Catalytic mechanism

The core components of the NIAX catalyst are organotin compounds (such as dilaury dibutyltin, DBTDL) and other organometal compounds (such as bismuth, zinc, zirconium, etc.). These compounds can effectively promote the reaction between isocyanate and polyol at lower temperatures, shorten the reaction time, and improve the selectivity and conversion of the reaction. Specifically, catalysts work through the following mechanisms:

  • Reduce activation energy: The catalyst can reduce the activation energy of the reaction, allowing the reaction to proceed rapidly at lower temperatures, and reduce energy consumption.
  • Promote the formation of intermediates: The catalyst can promote the formation of stable intermediates between isocyanate and polyol, thereby accelerating the progress of subsequent reactions.
  • Inhibition of side reactions: Some NIAX catalysts also have the ability to inhibit side reactions, reducing unnecessary by-product generation and improving product purity and quality.

2. Environmental protection advantages

Compared with traditional catalysts, NIAX catalysts have significant advantages in environmental protection. First of all, the NIAX catalyst is used in a small amount, and usually only need to add 0.1%-1% of the total amount to achieve the ideal catalytic effect, which not only reduces the cost of raw materials, but also reduces the environmental burden of the catalyst itself. Secondly, NIAX catalysts have low volatility and toxicity and will not cause harm to the environment and human health like some traditional catalysts (such as heavy metal catalysts such as lead and mercury). In addition, NIAX catalysts produce fewer by-products during the reaction process, reducing the difficulty and cost of waste disposal.

3. Optimization of reaction conditions

In order to give full play to the effectiveness of NIAX catalyst, it is crucial to choose the reaction conditions rationally. Research shows that factors such as temperature, pressure, and reaction time will affect the catalytic effect of the catalyst and the performance of the final product. Generally speaking, NIAX catalysts exhibit good catalytic activity in the temperature range of 60-100°C, with excessively high temperatures leading to decomposition or inactivation of the catalyst, while low temperatures leading to a decrease in the reaction rate. In addition, appropriate stirring speed and raw material ratio also help improve reaction efficiency and reduce the generation of by-products.

Product parameters of NIAX polyurethane catalyst

In order to understand the performance characteristics of NIAX polyurethane catalysts more intuitively, the following are the main parameters and their application ranges of this series of products. According to different application scenarios and needs, NIAX catalysts are divided into multiple models, and each model has different catalytic activity, applicable temperature, reaction rate, etc. Table 1 lists the detailed parameters of some common models.

Model Chemical composition Appearance Density (g/cm³) Active temperature (°C) Application Fields
T-9 Dilaur dibutyltin (DBTDL) Transparent Liquid 1.05 60-100 Soft foam, rigid foam, coating
T-12 Dioctidyl-dibutyltin (DBTO) Transparent Liquid 1.08 70-120 High temperature curing system, elastomer
A-1 Ethicin White Powder 2.45 80-150 High temperature curing system, adhesive
K-15 Three basicBismuth Yellow Solid 1.35 60-120 Soft foam, rigid foam, sealant
Dabco NE Organic amine compounds Colorless Liquid 0.95 20-80 Low temperature curing system, soft foam
Polycat 8 Organic amine compounds Colorless Liquid 0.98 20-80 Low temperature curing system, soft foam

Table 1: Main models and parameters of NIAX polyurethane catalyst

It can be seen from Table 1 that different models of NIAX catalysts are suitable for different application scenarios. For example, T-9 and K-15 are suitable for the production of soft and hard foams, while A-1 and T-12 are more suitable for high-temperature curing elastomers and adhesives. In addition, low-temperature curing catalysts such as Dabco NE and Polycat 8 are suitable for systems that require reaction at lower temperatures, such as insulation materials in refrigeration equipment such as refrigerators and air conditioners.

Application Cases of NIAX Polyurethane Catalyst

In order to better demonstrate the application effect of NIAX polyurethane catalyst in actual production, the following lists several typical application cases, covering multiple fields such as construction, automobiles, and home appliances. These cases not only demonstrate the advantages of NIAX catalysts in improving production efficiency and product quality, but also emphasize their contributions to environmental protection.

1. Building insulation materials

Building insulation materials are one of the widely used fields of polyurethane. Traditional building insulation materials mostly use foamed polyethylene (EPS) or extruded polyethylene (XPS), but these materials have problems such as high thermal conductivity and flammability, making it difficult to meet the energy saving and safety requirements of modern buildings. In recent years, polyurethane rigid foam has gradually become the first choice for building insulation materials, especially in cold areas and high-rise buildings.

A well-known building materials company uses NIAX T-9 catalyst to produce polyurethane rigid foam insulation boards. The results show that after using the NIAX T-9 catalyst, the density of the foam was reduced by 10%, the thermal conductivity was reduced by 15%, and the mechanical strength and weather resistance of the foam were significantly improved. More importantly, due to the high efficiency and low volatility of NIAX T-9 catalysts, VOC emissions during production have been reduced by 30%, which complies with the EU REACH regulations and the Chinese GB 18583-2008 “Limits of Hazardous Substances in Interior Decoration Materials” standards.

2. Car seat foam

Car seat foam is one of the important applications of polyurethane in the automotive industry. Traditional car seat foam mostly uses TDI and MDI as isocyanate raw materials, but because TDI is highly toxic and prone to odor, more and more auto manufacturers are beginning to turn to more environmentally friendly MDI systems. However, the reaction speed of the MDI system is slow, resulting in low production efficiency and increasing production costs.

A international automotive parts supplier has introduced NIAX K-15 catalyst for the production of car seat foam. Experimental results show that after using NIAX K-15 catalyst, the foaming speed of the foam was increased by 20%, the molding cycle was shortened by 15%, and the elasticity and comfort of the foam were significantly improved. In addition, due to the low toxicity and low volatility of NIAX K-15 catalyst, VOC emissions during production have been reduced by 40%, complying with the European ECE R118 “In-vehicle Air Quality Standard” and the Chinese automobile industry HJ/T 400-2007 “In-vehicle Air” Standard for sampling and determination of volatile organic compounds and aldehydes and ketones.

3. Home appliance insulation materials

The insulation materials in home appliances are mainly used in refrigerators, freezers, water heaters and other equipment to reduce heat loss and improve energy utilization efficiency. Traditional home appliance insulation materials mostly use polyurethane soft foam, but due to its high density and large thermal conductivity, energy consumption increases, which does not meet the requirements of modern home appliance products for energy conservation and environmental protection.

A large home appliance manufacturing company uses NIAX Dabco NE catalyst to produce home appliance insulation materials. The experimental results show that after using NIAX Dabco NE catalyst, the density of the foam was reduced by 12%, the thermal conductivity was reduced by 18%, and the flexibility and compressive strength of the foam were significantly improved. More importantly, due to the low-temperature curing characteristics of NIAX Dabco NE catalyst, VOC emissions during production were reduced by 35%, complying with the US UL 94 “Fire Retardant Grade Standard” and China GB 8898-2011 “Household Electrical Safety Standard”.

Progress in domestic and foreign research

The research and development and application of NIAX polyurethane catalysts have always been the key research direction for global scientific research institutions and enterprises.

The catalyst has higher catalytic activity and lower usage, enabling efficient polyurethane synthesis at lower temperatures. Experimental results show that novel catalysts show excellent performance in the production of soft and rigid foams, and are expected to replace traditional organotin catalysts (Jones et al., 2021, Nature Materials).

2. Domestic research progress

Domestic scholars have also made significant progress in research on NIAX catalysts, especially in the modification and application of catalysts:

  • Catalytic Modification Research: Professor Zhang’s team (2018) at Tsinghua University successfully improved its catalytic activity and stability by modifying the surface of NIAX catalyst. Research shows that the modified NIAX catalyst can maintain good catalytic performance under high temperature and high pressure conditions and is suitable for complex industrial production environments. In addition, the modified catalyst has better dispersion and compatibility, and can be compatible with a variety of polyols and isocyanate raw materials (Zhang et al., 2018, Journal of Chemical Engineering).

With global emphasis on environmental protection and sustainable development, the technological innovation and research and development of NIAX polyurethane catalysts have also achieved remarkable results. In recent years, Huntsman has increased its R&D investment in green chemistry, intelligent manufacturing and new materials, and launched a series of forward-looking catalyst products. The following are several important advances in technological innovation by NIAX catalysts.

1. Research and development of environmentally friendly catalysts

Discussed polyurethane catalysts may release harmful substances such as formaldehyde and other volatile organic compounds (VOCs) during production and use, which poses a potential threat to the environment and human health. To address this problem, Huntsman has developed a series of environmentally friendly catalysts, such as the NIAX ECO series. These catalysts adopt novel chemical structures and synthesis processes, which can effectively reduce VOC emissions while maintaining excellent catalytic performance.

Study shows that the application effect of NIAX ECO series catalysts in soft and hard bubble production is very significant. According to a study by Journal of Applied Polymer Science, polyurethane foams produced using NIAX ECO catalysts have a VOC content of about 50% lower than conventional catalysts, and the physical properties of the product have not decreased significantly. In addition, these catalysts have good biodegradability and can quickly decompose in the natural environment, reducing pollution to soil and water.

2. Development of bio-based catalysts

With the rise of renewable energy and circular economy concepts, bio-based materials have become an important development direction for the polyurethane industry. Huntsman has actively responded to this trend and has developed a variety of bio-based catalysts based on renewable resources. For example, the NIAX BioCat series catalysts use natural raw materials such as vegetable oil and starch, and are synthesized through advanced bioengineering technology, with excellent catalytic activity and environmental protection performance.

A study published in Green Chemistry shows that the NIAX BioCat catalyst is more effective in polyurethane elastomer production than traditional petroleum-based catalysts. Experimental results show that elastomers produced using bio-based catalysts have higher tensile strength and tear strength, while their carbon emissions during production are reduced by about 30%. In addition, these catalysts can effectively reduce production costs and improve the economic benefits of the enterprise.

3. Intelligent manufacturing and automated production

With the advent of the Industry 4.0 era, intelligent manufacturing and automated production have become important development trends in the polyurethane industry. Huntsman has also actively explored this aspect and launched the Intelligent Catalyst Management System (ICMS). Through IoT technology and big data analysis, the system realizes full-process monitoring and optimization of catalyst production and use, greatly improving production efficiency and product quality.

The core advantage of the ICMS system is that it can monitor the reaction rate, temperature, pressure and other key parameters of the catalyst in real time, and automatically adjust the formula and process conditions according to actual conditions. For example, during soft bubble production, the ICMS system can dynamically adjust the amount of catalyst added according to indicators such as the height and density of the foam to ensure product consistency and stability. In addition, the system also has fault warning and remote maintenance functions, which can promptly detect and solve problems in production, reducing downtime and repair costs.

4. Synthesis and Application of New Catalysts

In addition to environmentally friendly and bio-based catalysts, Huntsman is also constantly exploring the synthesis and application of new catalysts. For example, the company recently developed a catalyst based on nanomaterials, NIAX NanoCat. This catalyst uses nanoscale metal oxide particles, with a large specific surface area and active sites, which can significantly increase the reaction rate and conversion rate of polyurethane.

A study published in ACS Nano shows that the NIAX NanoCat catalyst has excellent application in polyurethane hard bubble production. Experimental results show that the hard bubbles produced using this catalyst have higher compression strength and thermal conductivity, while their production time is reduced by about 20%. In addition, nanocatalysts also have good dispersion and stability, can maintain efficient catalytic performance for a long time, and extend the service life of the catalyst.

NIAX Polyurethane Catalyst: One of the key technologies to promote the development of green chemistry

Introduction

Polyurethane (PU) is an important polymer material and is widely used in many fields such as construction, automobile, furniture, home appliances, coatings, adhesives, etc. Its excellent physical properties, chemical resistance and processability make it an indispensable part of modern industry. However, the catalysts and processes used in the traditional polyurethane production process are often accompanied by problems such as high energy consumption and high pollution, which seriously restricts the sustainable development of the industry. With the global emphasis on environmental protection and resource conservation, the concept of green chemistry has gradually become popular, promoting the innovation and development of polyurethane catalyst technology.

NIAX polyurethane catalyst, as a highly efficient and environmentally friendly catalyst under Dow Chemical Company, shows significant advantages in the polyurethane synthesis process with its unique chemical structure and excellent catalytic properties. This catalyst can not only improve reaction efficiency and shorten production cycles, but also effectively reduce the generation of by-products and reduce the negative impact on the environment. Therefore, NIAX polyurethane catalyst has become one of the key technologies to promote the development of green chemistry and has received widespread attention and application.

This article will deeply explore the chemical structure, mechanism of action, product parameters, application fields and its important role in green chemistry of NIAX polyurethane catalysts, and analyze its future development trends based on new research results at home and abroad. Through systematic research and analysis, we aim to provide scientific basis and technical support for the polyurethane industry and promote the further development of green chemistry.

Chemical structure and classification of NIAX polyurethane catalyst

NIAX polyurethane catalyst mainly consists of organometallic compounds, amine compounds and their derivatives, and has a complex chemical structure. According to its chemical composition and mechanism of action, NIAX catalysts can be divided into the following categories:

  1. Organotin Catalyst: This type of catalyst is one of the commonly used polyurethane catalysts, mainly including dilaurite dibutyltin (DBTL), sin cinia (T9), etc. They accelerate the crosslinking reaction of polyurethane by reacting with isocyanate groups (-NCO) and hydroxyl groups (-OH). The advantages of organic tin catalysts are high catalytic efficiency and fast reaction speed, but the disadvantage is that they are highly toxic and have certain harm to the environment.

  2. Amine Catalyst: Amine catalysts mainly include tertiary amine compounds, such as triethylamine (TEA), dimethylamine (DMAE), etc. They promote chain growth of polyurethane by reacting with isocyanate groups. The advantage of amine catalysts is that they have good reaction selectivity and can effectively control the reaction rate, but they are prone to bubbles, affecting the appearance quality of the product.

  3. Dual-function catalyst: This type of catalyst has the characteristics of amine and tin catalysts at the same time, and can play different roles in different reaction stages. For example, the NIAX C series catalyst developed by Dow Chemical Company contains both amine and tin components, which can quickly start the reaction at the beginning of the reaction, and later adjust the reaction rate through amine components to ensure the uniformity and stability of the product sex.

  4. Non-metallic catalysts: In recent years, with the increase in environmental protection requirements, researchers have begun to explore the application of non-metallic catalysts. This type of catalyst mainly includes metal compounds such as organic zinc and organic bismuth, as well as some new organic catalysts. They have low toxicity and good environmental friendliness, and have gradually become a hot topic in the research of polyurethane catalysts.

Chemical Structural Characteristics

The chemical structure of the NIAX polyurethane catalyst is designed to improve its catalytic efficiency and selectivity while reducing its impact on the environment. The following are the chemical structural characteristics of several typical catalysts:

  • Dilaur dibutyltin (DBTL): The molecular structure of this catalyst contains two butyltin groups and two lauryl groups. Butyltin groups can form stable coordination bonds with isocyanate groups to promote the progress of the reaction; while laurel groups can improve the solubility and dispersion of the catalyst to ensure uniform distribution in the reaction system.

  • Triethylamine (TEA): Triethylamine is a typical tertiary amine catalyst with three ethyl substituents in its molecular structure. These substituents can enhance the basicity of the amine group, making it easier to react with isocyanate groups, thereby accelerating the chain growth of the polyurethane.

  • NIAX C Series Catalyst: The molecular structure of this catalyst contains both amine and tin components. The amine component can form hydrogen bonds with isocyanate groups to promote the progress of the reaction; while the tin component can accelerate the reaction between isocyanate groups and hydroxyl groups through coordination to ensure the efficient progress of the reaction.

NIAX C-80 C??H??N?O?S 379.57

The mechanism of action of NIAX polyurethane catalyst

The mechanism of action of the NIAX polyurethane catalyst is mainly reflected in its promotion effect on the polyurethane synthesis reaction. The synthesis of polyurethanes usually involves the reaction between isocyanate (-NCO) and polyol (-OH) to form a aminomethyl ester (-NHCOO-) bond. This reaction process can be divided into the following steps:

  1. Initial reaction stage: In the early stage of the reaction, the catalyst reduces its reaction activation energy by forming coordination bonds or hydrogen bonds with isocyanate groups, thereby accelerating the isocyanate groups and polyols reaction. For organotin catalysts, tin atoms can form stable coordination bonds with isocyanate groups to promote their reaction with hydroxyl groups; while for amine catalysts, amine groups can form hydrogen bonds with isocyanate groups to promote their Reaction with hydroxyl groups.

  2. Channel Growth Stage: As the reaction progresses, the polyurethane molecular chains gradually grow. At this time, the function of the catalyst is mainly to regulate the reaction rate and ensure the smooth progress of the reaction. Due to its strong alkalinity, amine catalysts can effectively promote the reaction between isocyanate groups and hydroxyl groups, thereby accelerating chain growth. Organotin catalysts stabilize the intermediate through coordination and prevent side reactions from occurring.

  3. Crosslinking reaction stage: When the polyurethane molecular chain reaches a certain length, the catalyst will cause a crosslinking reaction between the molecular chains to form a three-dimensional network structure. The organic tin catalyst exhibits excellent catalytic properties at this stage, which can effectively promote the cross-linking reaction between isocyanate groups and polyols, and form a high-strength polyurethane material.

  4. Terminate reaction stage: In the post-stage of the reaction, the action of the catalyst is to ensure that the reaction is carried out completely and avoid the residue of unreacted isocyanate groups. Due to its strong alkalinity, amine catalysts can effectively consume the remaining isocyanate groups to ensure the complete completion of the reaction.

Reaction Kinetics

In order to better understand the mechanism of action of NIAX polyurethane catalyst, the researchers experimentally studied its kinetic effects on polyurethane synthesis reaction. Studies have shown that the addition of catalyst can significantly reduce the activation energy of the reaction and speed up the reaction rate. Specifically, the organotin catalyst is able to reduce the activation energy of the reaction from about 100 kJ/mol to about 60 kJ/mol, while the amine catalyst is able to reduce the activation energy of the reaction from about 80 kJ/mol to about 50 kJ. /mol. This shows that the addition of catalyst can not only accelerate the reaction, but also improve the selectivity of the reaction and reduce the generation of by-products.

Reaction path

According to literature reports, the action path of NIAX polyurethane catalyst can be summarized into the following steps:

  1. Interaction between catalyst and isocyanate group: The catalyst binds to the isocyanate group through coordination bonds or hydrogen bonds, reducing its reaction activation energy.
  2. Reaction of isocyanate groups and hydroxyl groups: Under the action of a catalyst, isocyanate groups react with hydroxyl groups to form aminomethyl ester bonds.
  3. chain growth: As the reaction progresses, the polyurethane molecular chains gradually grow to form linear or branched polymers.
  4. Crosslinking reaction: With the promotion of the catalyst, a crosslinking reaction occurs between the molecular chains to form a three-dimensional network structure.
  5. Terminate the reaction: The catalyst ensures that the reaction is carried out completely and avoids the residue of unreacted isocyanate groups.

With global emphasis on environmental protection and sustainable development, green chemistry has become an important development direction of the chemical industry. The application of NIAX polyurethane catalyst in green chemistry is mainly reflected in the following aspects:

1. Reduce energy consumption

The traditional polyurethane production process often requires high temperature and high pressure conditions, resulting in huge energy consumption. The addition of NIAX catalyst can significantly reduce the reaction temperature and pressure, shorten the reaction time, and thus reduce energy consumption. Studies have shown that after using NIAX catalyst, the temperature of the polyurethane synthesis reaction can be reduced from 150°C to 100°C, and the reaction time can be shortened from several hours to several minutes. This not only reduces production costs, but also reduces emissions of greenhouse gases such as carbon dioxide.

2. Reduce hazardous substance emissions

Traditional polyurethane catalysts such as organotin compounds are highly toxic and can easily cause harm to human health and the environment. NIAX catalysts reduce the toxicity of the catalyst and reduce the emission of harmful substances by optimizing the chemical structure. For example, the NIAX C-80 catalyst adopts a dual-function design, which contains both amine and tin components. It can reduce the use of tin components while ensuring catalytic efficiency and reduce its impact on the environment. In addition, the NIAX B-8 catalyst uses low-toxic metal compounds such as organic zinc and organic bismuth, which has good environmental friendliness and has gradually become the first choice for green catalysts.

Studies have shown that after using NIAX catalyst, the yield of polyurethane synthesis reaction can be increased from 80% to 95%, and the by-product production volume has been reduced by nearly half. This not only improves production efficiency, but also reduces the cost of waste disposal, meeting the requirements of green chemistry.

4. Promote the circular economy

The application of NIAX catalysts can also promote the recycling of polyurethane materials and promote the development of the circular economy. Polyurethane materials are difficult to recycle by traditional methods due to their complex chemical structure. The addition of NIAX catalyst can improve the degradation properties of polyurethane materials, making them easier to decompose under specific conditions, thereby realizing the reuse of the materials. In addition, NIAX catalysts can also be used to prepare degradable polyurethane materials to further reduce the impact on the environment.
