Abstract

The invention discloses a wear-resistant and high-temperature resistant silicone rubber. The wear-resistant and high-temperature resistant silicone rubber comprises the following components in parts by weight: 100-150 parts of methyl vinyl silicone rubber, 13-20 parts of fumed silica, 25-30 parts of carbon black, 40-45 parts of quartz powder, 30-42 parts of aluminium hydroxide, 3-8 parts of methyl hydrogen silicone oil, 2-5 parts of polytetrafluoroethylene, 1-3 parts of stearic acid, 4-13 parts of zinc oxide, 1.5-4 parts of 2-sulfhydryl benzothiazole, 6-11 parts of p-phenylenediamine and 8-14 parts of sulphur. The wear-resistant and high-temperature resistant silicone rubber has the advantages of wide raw material sources, low cost, excellent silicone rubber product condition, particularly good wear resistance and high temperature resistance and moreover the preparation method is simple.

Description

technical field [0001] The invention relates to a rubber product and a preparation method thereof, in particular to a wear-resistant and high-temperature resistant silicone rubber and a preparation method thereof. Background technique [0002] Silicone rubber has excellent electrical insulation properties, excellent high temperature resistance, low temperature resistance, corrosion resistance, radiation resistance, atmospheric aging resistance, etc., and has good elasticity, high stretchability, and good adhesion, so it is widely used in electronic and electrical , automobiles, ships, aerospace, office products and other industries. However, due to the rapid development of science and technology, the tearing, tensile and elongation properties of silicone rubber have gradually failed to meet the current rapid development needs. How to prepare silica gel with good physical properties, wear resistance, and good flame retardancy has become an urgent technology to be solved. que...
