1. Chemical composition and molecular structure

The main components of the low-odor reactive type 9727 include epoxy resin, polyurethane prepolymer, acrylic ester monomer and other functional additives. These components are combined together through a special synthesis process to form a stable cross-linking network structure. According to foreign literature (Smith et al., 2018), this crosslinking network structure imparts excellent mechanical strength and chemical resistance to 9727 materials, while reducing the release of volatile organic compounds (VOCs), thereby significantly reducing the odor .

2. Physical performance parameters

The following table lists the main physical performance parameters of the low-odor responsive 9727, which are critical to assess their applicability in different application scenarios.

parameter name Unit Value Range Remarks

The chemical composition and physical properties of low-odor reaction type 9727

The low odor reactive type 9727 is a polymer material based on polyurethane (PU), whose main components include isocyanate, polyol, catalysts and other additives. These components form a crosslinking network structure through chemical reactions, which impart excellent physical and chemical properties to the material. The following are the detailed chemical composition and physical performance parameters of 9727:

Chemical composition

  1. Isocyanate: As one of the main reaction monomers of 9727, isocyanate (such as MDI, TDI, etc.) undergoes condensation with polyol during the reaction process to form a polyurethane segment. The choice of isocyanate has an important influence on the hardness, flexibility and chemical resistance of the material.

  2. Polyol: Polyols are another key raw material, and common types include polyether polyols, polyester polyols and polycarbonate polyols. They react with isocyanate to form a polyurethane backbone, which determines the elasticity, wear resistance and tear resistance of the material. Different types of polyols can adjust the hardness and processing properties of the material.

  3. Catalytics: Catalysts are used to accelerate the reaction of isocyanate and polyols, shorten the curing time and improve the reaction efficiency. Commonly used catalysts include organotin compounds (such as dilaury dibutyltin), amine catalysts and metal chelates. The choice of catalyst affects the final performance and odor control of the material.

  4. Adjuvant: In order to improve the processing performance and use effect of the material, a variety of additives are also added to 9727, such as plasticizers, stabilizers, antioxidants, ultraviolet absorbers, etc. These additives can enhance the flexibility, aging resistance and UV resistance of the material while reducing the release of harmful substances.

Its tensile strength and elongation at break are excellent, and are suitable for applications where high toughness and tear resistance are required. In addition, the heat resistance and chemical resistance of 9727 are also very outstanding, and can work stably in extreme environments for a long time. Importantly, its VOC content is extremely low, complies with strict international environmental protection standards, and can effectively reduce the impact on air quality.

Production technology and technical difficulties

The production process of the low-odor reaction type 9727 mainly includes four stages: raw material preparation, mixing reaction, curing molding and post-treatment. At each stage, process parameters need to be strictly controlled to ensure product quality and environmental performance. The following are detailed descriptions of each stage and key technical difficulties:

1. Raw material preparation

Before production of 9727, all raw materials must be strictly screened and pretreated. In particular, isocyanate and polyols, their quality is directly related to the performance of the final product. In order to ensure the smooth progress of the reaction, these raw materials are usually required.Dry, filter and purify the treatment to remove moisture, impurities and low molecular weight by-products. In addition, the selection of catalysts and additives is also very important, and the precise proportion must be carried out according to the specific formulation requirements.

2. Mixed reaction

Mixed reaction is the core link of 9727 production, which directly affects the physical properties and odor control of the material. During this process, isocyanate and polyol are mixed in a certain proportion, and a condensation reaction occurs under the action of the catalyst to form a polyurethane segment. To ensure uniform and sufficient reaction, high-speed stirring or static mixers are usually operated. At the same time, the reaction temperature, time and pressure need to be controlled to avoid premature curing or excessive by-products. Studies have shown that too high reaction temperature will lead to the decomposition of isocyanate and produce harmful gases; while too low temperature will slow down the reaction rate and prolong the production cycle. Therefore, the optimal reaction temperature is generally controlled between 60-80°C (Santos et al., 2018).

3. Curing and forming

Currective molding refers to pouring the reaction mixture into a mold or coating it on the surface of the substrate to gradually harden and form the final product shape. The curing process of 9727 is divided into two stages: preliminary curing and complete curing. Initial curing is usually carried out at room temperature, ranging from hours to dozens of hours, depending on the formulation and environmental conditions. Complete curing will need to be carried out at high temperatures (80-120°C) for several minutes to several hours to ensure the material achieves optimal physical properties. In order to speed up the curing speed, auxiliary means such as microwave heating or infrared radiation are sometimes used. However, excessively rapid curing may lead to internal stress accumulation, affecting the dimensional stability and mechanical strength of the product (Zhang et al., 2019).

4. Post-processing

Post-treatment mainly refers to the surface modification, grinding, cutting and other processing operations of cured 9727 products to meet specific application needs. In addition, it is also necessary to conduct quality inspections to ensure that all performance indicators meet the standards. For some special applications, such as electronic packaging, antistatic treatment or conductive coating may also be required. Care should be taken to avoid damage to the material during post-treatment, especially for products with thin walls or complex shapes, and appropriate tools and techniques should be used (Li et al., 2020).

Key Technological Difficulties

Although the production process of 9727 is relatively mature, it still faces some technical difficulties in actual production, mainly including the following points:

  1. Odor Control: Although 9727 itself has a low VOC content, it may still produce a small amount of odor during production and use. This is mainly due to incompletely reacted isocyanate and other volatile by-products. In order to further reduce odor, it is necessary to optimize the formulation design, select low-odor raw materials and catalysts, and improve production processes, such as vacuum degassing or low-temperature reactions (Smith et al., 2021).

  2. Enhanced Weather Resistance: 9727 When exposed for a long time in outdoor environments, it is susceptible to ultraviolet rays, oxygen and water vapor, causing the material to age, discolor and even crack. To this end, researchers have developed a series of modification techniques and additives, such as the introduction of silicone segments, the addition of nanofillers or the use of ultraviolet absorbers, etc., to improve the weather resistance and service life of the material (Wang et al., 2022) .

  3. Cost Control: The production cost of 9727 is relatively high, especially in high-end applications such as aerospace and medical equipment. To reduce production costs, enterprises can achieve this by optimizing formulations, improving production efficiency and expanding scale. In addition, alternative raw materials and recycling technologies can be explored to reduce dependence on imported raw materials (Chen et al., 2023).
