Abstract

The invention discloses a rubber material of an electric wire and a cable. The insulation material is prepared from the following raw materials in parts by weight: 30 to 60 parts of ethylene-propylene-diene-terpolymer rubber, 15 to 35 parts of butyl rubber, 50 to 80 parts of silicon rubber, 10 to 20 parts of epoxidized methyl acetoricinoleate, 2 to 8 parts of magnesium hydroxide, 1 to 6 parts of magnesium oxide, 1 to 3 parts of zinc n-butylxanthate, 3 to 9 parts of maleic anhydride, 1 to 6 parts of anti-aging agent, 2 to 5 parts of accelerant, 3 to 9 parts of ethylene glycol, 1 to 4 parts of sodium hexametaphosphate, 2 to 6 parts of sepiolite fiber, 6 to 12 parts of O-benzenedicarboxylic acid diallyl ester, 1 to 6 parts of poly-tetramethylene oxide, 2 to 7 parts of trifluoro-propyl methyl silicone oil, 3 to 6 parts of benzoyl peroxide,1 to 3 parts of sulfur, and 2 to 8 parts of lignite wax. The rubber material of the electric wire and the cable has the advantages that the anti-aging property and abrasion-resistant property are good; the service life of the cable is favorably prolonged; the application field is expanded.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, in particular to a wire and cable rubber material. Background technique [0002] The rapid development of economy and society also promotes the progress of cable material production technology. At present, the cable insulation protection layer is mainly made of silicone rubber and polyurethane materials. Polyurethane materials rely on excellent physical and chemical properties, high production efficiency, and low investment costs. Advantages are widely used in the field of cable materials, while silicone rubber is odorless, non-toxic, resistant to high temperatures and cold. However, as people have higher and higher requirements on the performance indicators of cable materials, the aging resistance and wear resistance of traditional cable materials need to be improved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a wire and cable rubbe...
