Abstract

The invention discloses a high-speed-extruding oil-proof wear-resisting irradiation crosslinking rubber material and a preparation method thereof. The high-speed-extruding oil-proof wear-resisting irradiation crosslinking rubber material comprises the following components in parts by weight: 30 to 70 parts of chlorinated polyethylene, 4 to 20 parts of polyethylene, 10 to 30 parts of magnesium hydrate, 5 to 20 parts of calcium carbonate, 1 to 5 part(s) of stabilizer, 1 to 5 part(s) of compatilizer, 1 to 5 part(s) of silicone powder, 1 to 5 part(s) of silica, 1 to 10 part(s) of plasticizer, and 2 to 5 parts of carbon black. The rubber material disclosed by the invention can achieve the extruding at a high speed over 600m/min, has extremely high production efficiency and high cost performance on oil resistance, can meet the requirements of HPN-R lines of a UL507 standard in the aspect of wear-resisting performance, and also has high flame retardation.

Description

Technical field: [0001] The invention belongs to the technical field of organic high polymers, and more specifically relates to a high-speed extrusion oil-resistant and wear-resistant radiation-crosslinked rubber material and a preparation method thereof. Background technique: [0002] Chlorinated polyethylene (CPE) is a kind of artificial rubber with high cost performance, which has excellent mechanical strength, electrical insulation performance, heat aging resistance, weather aging resistance, oil resistance, solvent resistance and flame resistance. Compared with chloroprene rubber, the oil resistance performance is slightly lower than that of chloroprene rubber under the premise of meeting national standards, but the price is only 1 / 3-1 / 2 of chloroprene rubber; compared with chlorosulfonated polyethylene rubber, all properties Comparable, but the price is only 1 / 2-2 / 3 of chlorosulfonated polyethylene rubber; compared with natural rubber and ethylene propylene rubber, alt...
