Abstract

The invention discloses a nano-barite powder modified chlorosulfonated polyethylene rubber cable material, which is prepared from the following raw materials in parts by weight: 100-120 parts of chlorosulfonated polyethylene rubber CSM2305, 20-30 parts of cis-1,4-polybutadiene rubber BR9000, 10-15 parts of epichlorohydrin rubber H45, 5-10 parts of dioctyl adipate, 5-10 parts of butyl ester of epoxy fatty acid, 10-15 parts of diphenyl isooctyl phosphate, 3-6 parts of 2,4-dichlorobenzoyl peroxide, 1-2 parts of 2,2'-dithio-dibenzo thiazole, 2-3 parts of stearic acid, 1-2 parts of lead oxide, and the like. The cable material not only has excellent flame retardance and incombustibility, but also has the advantages of good high and low temperature resistance, corrosion resistance, water resistance, wear resistance, ozone resistance, ageing resistance and the like at the same time, and is durable in use.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a chlorosulfonated polyethylene rubber cable material modified by nano barite powder. Background technique [0002] Since the industrialization of chlorosulfonated polyethylene rubber in 1952, it has been valued by the cable industry because of its excellent aging resistance, heat resistance and low temperature resistance, oil resistance, flame resistance, abrasion resistance, and electrical insulation. . At present, it has replaced traditional styrene-butadiene, natural, and butyl rubber, and is widely used in low- and medium-voltage cables for marine and mobile use. However, the mechanical strength of cable materials produced by chlorosulfonated polyethylene rubber is poor at present, which cannot meet the actual needs. Therefore, the development and development of high-performance chlorosulfonated polyethylene rubber cable materials has been valued by the cable industry. Con...
