Application of sericite in rubber industry

In the rubber industry, sericite is a good filler or extender, which can reduce the rubber content of materials and thus reduce production costs. Sericite has a unique sheet structure, which can effectively improve the damping performance of rubber. Its good compression resistance, tensile resistance, light resistance, fire resistance, weather resistance, heat resistance, acid resistance and electrical insulation physical and chemical properties can improve the mechanical properties, heat resistance, aging resistance and other functions of rubber products with sericite added, and can be used in the development of special rubber products.

The application research of ultra-fine sericite powder added to natural rubber, styrene butadiene rubber, neoprene rubber and other rubbers shows that under the same conditions, the reinforcement performance of sericite powder is obviously better than that of common inorganic reinforcement fillers such as calcium carbonate, clay, active silica powder, etc., and its reinforcement performance is only inferior to that of semi reinforced carbon black. The application study of rubber products with sericite powder showed that the mechanical properties such as tensile strength, impact strength and tensile strength were greatly improved.

Chen Jianwen added wet ground sericite powder to natural rubber and styrene butadiene rubber, and the results showed that it not only enhanced the reinforcement performance of the products, but also the appearance of the products was smooth and the hand feeling was good, and it could partially replace carbon black or white carbon black.
