Rubber accelerator, also known as rubber additive, is a substance that is indispensable in the production of rubber products. It is used to improve the quality and performance of rubber products by adjusting the hardness, abrasion resistance, tensile properties and other properties of rubber. Rubber accelerators can be divided into vulcanization accelerators, cross-linking agents, anti-aging agents, processing aids, lubricants, etc. according to their functions.
Vulcanization accelerator is one of the Z common accelerators in the rubber industry and can be divided into two categories: inorganic vulcanization accelerators and organic vulcanization accelerators. Inorganic vulcanization accelerators include sulfur, potassium thiosulfate, ferrous sulfate, zinc sulfide, etc.
Cross-linking agent is a compound that can cross-link rubber molecules to each other. Its main function is to improve the mechanical properties, heat resistance and corrosion resistance of rubber by enhancing the cross-linking structure of rubber, so that rubber products have better mechanical stability and long life. Cross-linking agent is divided into organic cross-linking agent and inorganic cross-linking agent.
Anti-aging agent is a compound that can slow down the aging process of rubber. Application of anti-aging agent can greatly improve the aging resistance of rubber products, so that they have better durability and long life. Anti-aging agents can be divided into antioxidants, ultraviolet absorbers, absorbers, etc.
Processing aids is a compound to improve the processing performance of rubber. It can reduce the viscosity of rubber, improve mobility, so that it is easy to process molding. Processing aids can be divided into plasticizers, softeners, dispersants, etc.
Lubricant is a compound that can reduce the friction and wear of rubber products. Application of lubricants can improve the service life of rubber products and reduce maintenance and replacement. Lubricants can be divided into two types: dry lubricants and liquid lubricants.
