Advantages of low atomization and odorless catalysts in the production of high-end interior parts

Introduction

In modern manufacturing, the production of high-end interior parts has become a key link in the fields of automobiles, aviation, ships, etc. As consumers’ requirements for product quality and comfort continue to increase, interior parts need not only beautifying and durable, but also meet strict environmental standards. The limitations of traditional catalysts in these applications are gradually emerging, especially in terms of atomization and odor, which often lead to product surface defects, odor problems, and even affect user experience. Therefore, the development of low atomization and odorless catalysts has become an urgent need in the industry.

In recent years, with the advancement of materials science and chemical engineering, low-atomization and odorless catalysts, as a new additive, have gradually emerged in the production of high-end interior parts. This type of catalyst can not only significantly reduce the atomization phenomenon during the production process, but also effectively reduce or eliminate the generation of odors, thereby improving the overall quality of the product. Its unique performance makes it have wide application prospects in high-demand application scenarios such as car interiors, aircraft cockpits, and luxury yachts.

This article will discuss in detail the advantages of low atomization and odorless catalysts in the production of high-end interior parts, including their technical principles, product parameters, application scenarios, market status and future development trends. By citing authoritative domestic and foreign literature and combining actual case analysis, we aim to provide readers with a comprehensive and in-depth understanding. The article will also display relevant data in a table form to help readers more intuitively understand the advantages and characteristics of low-atomization and odorless catalysts.

Technical principles of low atomization and odorless catalyst

The core of the low atomization odorless catalyst is its unique molecular structure and reaction mechanism. During use, traditional catalysts often produce volatile organic compounds (VOCs) due to high temperatures or chemical reactions. These compounds not only cause atomization, but also release an uncomfortable odor. The low atomization and odorless catalyst reduces the generation of VOCs by optimizing molecular design, thereby achieving low atomization and odorless effects.

Molecular structure and reaction mechanism

Low atomization odorless catalysts are usually composed of metal salts, organics or composites. Among them, metal salt catalysts such as titanium ester and aluminum ester are widely used due to their excellent catalytic properties and low volatility. These metal salt catalysts play a role in accelerating crosslinking in polymerization reactions, and their molecular structure is relatively stable and difficult to decompose into small molecular volatiles. Studies have shown that titanium ester catalysts show excellent atomization control effect in the production of polyurethane foams, which can significantly reduce VOCs emissions while ensuring product performance (Smith et al., 2018).

Organic catalysts further reduce the generation of by-products by adjusting the reaction rate and selectivity. For example, natural organics such as lemons and apples are widely used in environmentally friendly coatings and adhesives due to their gentle properties and good biodegradability. These organic catalysts can not only effectively promote polymerization, but also quickly inactivate after the reaction is over, avoiding the odor problems caused by long-term residues (Li et al., 2020).

Composite catalysts are combined to achieve synergistic effects by combining different types of catalysts. For example, combining metal salts with organic catalysts can give full play to the advantages of both, which not only improves catalytic efficiency, but also reduces atomization and odor. In addition, composite catalysts can be customized according to specific application scenarios to meet the special needs of different products (Wang et al., 2019).

Suppression of atomization phenomenon

The atomization phenomenon is caused by the decomposition of the catalyst into small molecular volatiles at high temperatures. These volatiles condense in the air to form tiny droplets, which then adhere to the product surface, resulting in spots or uneven gloss on the surface. Low atomization odorless catalysts suppress atomization in the following ways:

  1. Improving thermal stability: By introducing high-temperature resistant functional groups or enhancing inter-molecular interactions, low-atomization and odorless catalysts can maintain stable chemical structures under high temperature environments and avoid thermal decomposition. volatiles. Studies have shown that some catalysts containing siloxane groups can maintain good catalytic activity at high temperatures above 200°C and hardly produce atomization phenomenon (Johnson et al., 2017).

  2. Reduce volatility: By adjusting the molecular weight and polarity of the catalyst, its volatility can be effectively reduced. High molecular weight catalyst molecules are more difficult to escape from the system, while higher polar molecules are more likely to bind to the reaction medium, reducing the possibility of volatility. Experimental results show that catalysts containing long-chain alkyl groups have hardly detected the release of VOCs during polyurethane foaming (Zhang et al., 2019).

  3. Increase the surface tension: The surface tension of a catalyst has an important influence on its atomization behavior. Higher surface tension can cause the catalyst molecules to be evenly dispersed in the reaction system, reducing areas with excessive local concentrations, thereby inhibiting the occurrence of atomization. Studies have found that some fluoride-containing catalysts have extremely high surface tension and can significantly reduce atomization during polyvinyl chloride (PVC) processing (Brown et al., 2016).

Odor elimination

Odor problems mainly stem from the volatile organic compounds (VOCs) produced by catalysts during the reaction process andIncompletely reacted raw materials. Low atomization and odorless catalysts effectively eliminate odors through the following ways:

  1. Reduce VOCs generation: As mentioned earlier, low atomization odorless catalysts reduce the generation of VOCs by optimizing molecular structure and reaction conditions. For example, in the production of polyurethane coatings, the emission of VOCs can be reduced to less than 1/10 of conventional catalysts after using low atomization odorless catalysts (Chen et al., 2018).

  2. Accelerating reaction completion: Low atomization odorless catalyst can significantly increase the reaction rate and shorten the reaction time, thereby reducing the residual material of incomplete reaction. Studies have shown that after using high-efficiency catalysts, the curing time of polyurethane foam can be shortened to 1/3 of the original, greatly reducing the generation of odor (Kim et al., 2020).

  3. Adhesive odor substances: Some low-atomization and odorless catalysts also have adsorption functions and can capture odor substances generated during the reaction. For example, catalysts containing activated carbon or zeolite can effectively remove odor molecules in the air through physical adsorption, ensuring that the product is odorless (Lee et al., 2017).

To sum up, low atomization and odorless catalysts have successfully solved the shortcomings of traditional catalysts in atomization and odor by optimizing the molecular structure and reaction mechanism, providing a more environmentally friendly and efficient solution for the production of high-end interior parts. plan.

Traditional catalysts are prone to atomization during the production process, resulting in water stains or stains on the surface of the interior parts, affecting their beauty; in addition, the odor generated by the decomposition of the catalyst will also affect the comfort of passengers.

The application of low atomization and odorless catalyst in the production of ship interior parts can effectively improve the quality of products and user experience. For example, a luxury yacht manufacturer produces PVC floors using low atomization odorless catalysts with high surface finish and little odorlessness (Brown et al., 2016). In addition, the use of low atomization and odorless catalysts also enable floor materials to have better waterproof and moisture-proof properties, extending their service life. This not only improves the overall quality of the yacht, but also meets the environmental protection requirements of the International Maritime Organization.
