Abstract

The invention relates to the technical field of a macromolecular material, in particular to a cable sheath material. The cable sheath material is prepared from the following raw materials in parts by weight: 50 to 95 parts of chlorinated polyethylene, 20 to 35 parts of phenolic resin, 10 to 20 parts of nitrile rubber, 5 to 15 parts of ammonium polyphosphate, 5 to 16 parts of carbon fiber, 6 to 10 parts of copper ammonia fiber, 4 to 10 parts of maleic anhydride grafted polyethylene, 2 to 7 parts of calcium stearate, 2 to 6 parts of carbon black, 1 to 6 parts of asbestos, 10 to 15 parts of nylon, 5 to 12 parts of zeolite powder, 5 to 10 parts of calcium silicate and 2 to 8 parts of silane coupling agents. The cable sheath material has the advantages of excellent mechanical performance, good anti-tearing performance, good tensile intensity, excellent anti-aging performance and long service life.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a cable sheathing material. Background technique [0002] Chlorinated polyethylene is a high-molecular random chloride obtained by replacing the hydrogen atoms on the secondary carbon atoms in the molecular structure of high-density polyethylene (HDPE) with chlorine atoms. CPE with a chlorine mass fraction of about 35% has high strength, good elasticity, flame retardancy, oil resistance, solvent resistance, ozone resistance, heat aging resistance, weather resistance, and good processing performance because of its molecular structure does not contain double bonds. Filling, large output, low price and other advantages. With the development of the wire and cable industry, people put forward higher and stricter performance requirements for cable products. Rubber-type chlorinated polyethylene (CPE), as a new type of sheath material, has gradually replaced nitrile rubber, w...
