Acrylic and silicon PU are both important parts of the current stadium construction, so what are the differences between the two in essence? What if you determine whether a venue is going to be built with an acrylic or a silicon PU field? Today, Youzheng Sports will give you a detailed introduction to what is the difference between acrylic courts and silicon PU courts. February** Dynamic Incentive Program
1. Definitions and Ingredients
Acrylic acid, whose chemical name is methacrylic acid, is one of the most basic organic acids that is widely found in nature and has a variety of important uses. In the production and use of acrylic acid, due to its multiple functional groups, it can be chemically modified in a variety of ways, resulting in a series of polymers with different properties.
Silicone PU is a polyurethane elastomer material based on silicone modification, which is mainly composed of silicone elastomers, polyurethane components and other additives.
2. Performance and characteristics
Acrylic materials have the advantages of good wear resistance, weather resistance, water resistance, oil resistance and chemical resistance, so they have been widely used in coatings, inks, adhesives and other fields. In addition, acrylic materials also have good transparency, gloss and high elasticity, so they are also commonly used in the manufacture of optical instruments, spectacle lenses, medical devices and other fields.
As a new type of polyurethane elastomer material, silicon PU has excellent weather resistance, high and low temperature resistance and electrical insulation properties. In addition, silicon PU also has good anti-slip, shock absorption and chemical corrosion resistance, so it has been widely used in automotive, electronics, aerospace, chemical industry and other fields.
Third, the field of application
Acrylic materials occupy a dominant position in coatings, inks, adhesives and other fields due to their excellent properties and wide range of applications. Among them, acrylic adhesives have the characteristics of strong adhesion, fast curing speed and good weather resistance, and are widely used in home, construction, packaging, printing and other fields. In addition, acrylic acid can also be used to prepare functional polymer materials, such as ion exchange resins, superabsorbent resins, etc., and has a wide range of application prospects in environmental protection, energy, medical and other fields.
As a new type of polyurethane elastomer material, silicon PU has been widely used in automobiles, electronics, aerospace, chemical industry and other fields. For example, in the automotive industry, silicon PU can be used to make seals, shock absorbers, fuel tank sealing materials, etc.; In the electronics industry, silicon PU can be used to make insulating materials and protective coatings for electronic components; In the aerospace field, silicon PU can be used to make wear-resistant coatings and sealing materials for aircraft parts.
Fourth, the preparation method
The preparation methods of acrylic acid mainly include propane oxidation method, acrylonitrile hydrolysis method, etc. Among them, propane oxidation is the most commonly used preparation method in industry, which produces acrylic acid by oxidizing propane in oxygen. The acrylonitrile hydrolysis method is to hydrolyze acrylonitrile and water under the action of a catalyst to generate acrylic acid and ammonia.
The preparation methods of silicon PU mainly include prepolymer synthesis method and direct polymerization method. In the prepolymer synthesis method, polyurethane prepolymers and silicone prepolymers are first synthesized, and then the two are mixed and cured. The direct polymerization method is to mix and polymerize isocyanates and silicon-containing polymers to obtain silicon PU elastomers.
5. Development trend and future prospects
With the continuous progress of science and technology and the expansion of application fields, acrylic acid and silicon PU will continue to develop in the future. The application prospect of acrylic in the fields of environmentally friendly coatings and functional polymer materials will be more extensive. As a high-performance polyurethane elastomer material, the application of silicon PU in high-end manufacturing and special fields will continue to expand.
