Abstract

The invention discloses a low-smoke flame-retardant rubber material for automobile wires and cables and a manufacturing method of the rubber material. The low-smoke flame-retardant rubber material is prepared from, by weight, 44-58 parts of chlorosulfonated polyethylene rubber, 27-43 parts of epichloro-hydrin rubber, 16-28 parts of butadiene-styrene bromination copolymer, 24-36 parts of light calcium powder, 17-29 parts of natural fiber brucite, 8-16 parts of tetrabromobisphenol S bis (2,3-dibromopropyl) ether, 10-15 parts of coumarone resin, 3-4 parts of stannous chloride, 2-3 parts of triallyl isocyanurate, 14-22 parts of expandible graphite, 12-18 parts of hydrated basic magnesium carbonate, 10-15 parts of tris(2-butoxyethyl) phosphate, 4-5 parts of bis(1-(tert-butylperoxy)-1-methylethyl)-benzene, and 3-6 parts of auxiliary. The rubber material is excellent in flame retardance and low in smoke, and has excellent mechanical performance, ageing resistance, heat resistance and corrosion resistance.

Description

technical field [0001] The invention relates to a low-smoke flame-retardant rubber material for automobile wires and cables and a preparation method thereof, belonging to the field of rubber materials. Background technique [0002] Rubber products are various rubber products produced from natural and synthetic rubber, including rubber products remanufactured from waste rubber. There are many kinds of rubber products, with good physical and mechanical properties and high elasticity. They are widely used in various parts of automobiles, including tires, rubber hoses, transmission belts, sealing products, shock-absorbing rubber parts and safety products. The rubber parts used in a car are as follows: 100-200 species, as many as 200-500. In recent years, with the rapid development of the automobile industry, the performance requirements of rubber products are getting higher and higher. The flame retardancy of rubber materials for automobile wire and cable in the existing market...
