Abstract

The invention discloses a corrosion resistant silicone rubber material and a preparation method thereof. The material consists of the following raw materials by weight: 58-74 parts of nitrile silicone rubber, 32-46 parts of chloroprene rubber, 24-36 parts of polyether-ether-ketone, 5-8 parts of fluoroplast, 2-3 parts of triallyl isocyanurate, 6-12 parts of methyl vinyl silicone oil, 10-15 parts of hydroxyethyl methacrylate, 5-10 parts of coal tar pitch, 3-4 parts of N,N'-4,4'-diphenylmethane-bismaleimide, 2-3 parts of p-tert-butyl benzoic acid-Zn, 1-2 parts of dicumyl peroxide, 5-10 parts of ethylhexyl epoxystearate, 15-20 parts of acetylene black, 1-2 parts of cadmium stearate, 5-10 parts of white mud powder, 10-15 parts of diisobutyl phthalate, 1-2 parts of N-(4-anilino phenyl)-methacrylamide and 3-5 parts of an assistant. The silicone rubber material of the invention has excellent corrosion resistance, especially acid and alkali resistance and salt fog resistance, and also has good physical and mechanical properties and excellent aging resistance, wear resistance and high-temperature resistance, can be used in harsh and complex environment, has wide range of application and huge market prospect.

Description

technical field [0001] The invention relates to a corrosion-resistant silicone rubber material and a preparation method thereof, belonging to the technical field of silicone rubber. Background technique [0002] Silicone rubber is a polymer material with polysilane as the main chain. Due to the non-polar and weak intermolecular interactions of the main chain siloxane segment, it has good thermal stability, weather resistance, aging resistance and electrical properties. Its mechanical properties are quite stable in a wide temperature range (-50~120°C), and it has been widely used in aerospace, electronic and electrical industries and other fields. With the development of science and technology, higher requirements are put forward for the corrosion resistance of silicone rubber. However, the corrosion resistance of silicone rubber in the existing market can no longer meet the needs of special fields. Therefore, it is necessary to modify the silicone rubber to obtain a silicon...
