Abstract

The invention discloses a chlorinated polyethylene cable sheath for a coal mine. The chlorinated polyethylene cable sheath comprises the following raw materials by weight: 100 parts of chlorinated polyethylene 135B, 3 to 5 parts of a vulcanizing agent 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane, 1 to 1.5 parts of a co-vulcanizing agent trimethylol trimethacrylate, 3 to 5 parts of a calcium-zinc stabilizing agent, 10 to 15 parts of precipitated white carbon black, 20 to 30 parts of potter's clay, 3 to 4 parts of oxidized polyethlene wax, 8 to 12 parts of magnesium oxide, 2 to 5 parts of chlorinated paraffin, 15 to 20 parts of magnesium hydroxide, 1 to 3 parts of tritolyl phosphate, 1.2 to 1.3 parts of an auxiliary crosslinking agent TAIC, 2 to 5 parts of paraffin, 20 to 30 parts of powdered steatile and 50 to 60 parts of nanometer kaolin. The chlorinated polyethylene cable sheath provided by the invention has excellent heat resistance and flame retardation performance, high hardness, good resilience and small permanent compression set.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a chlorinated polyethylene cable sheath for coal mines. Background technique [0002] The mining shearer cable is used as the connection line of the coal mining equipment in the coal mine. Since the shearer cable runs back and forth hundreds or even thousands of times a day with the coal cutter head, with the electric coal mining in open-pit coal mines and underground mines With the development of machinery, the performance requirements of mining cables are also more stringent. Not only the insulation layer of the cable is required to have excellent electrical properties, but the sheath material is also required to have excellent physical and mechanical properties. In addition, gas gas is unavoidable in the mine, and there is a danger of combustion and explosion. How to prepare a cable sheath with high hardness, good resilience, small permanent compression deformation, heat...
