Abstract

The invention discloses a wear-resistant and aging-resistant power cable sheath material, which comprises the following raw materials in parts by weight: 30-40 parts of nitrile rubber, 20-30 parts of polyvinyl chloride, 20-30 parts of phenolic resin, and 10-30 parts of carbon fiber 18 parts, 10-15 parts of carbon black, 12-18 parts of organic montmorillonite, 10-15 parts of microcrystalline cellulose, 0.5-2 parts of N,N-phenyl-p-phenylenediamine, 1-2 parts of stearic acid , 10-15 parts of flame retardant, 3-5 parts of paraffin, 1-1.5 parts of anti-aging agent. The tensile strength of the cable sheath material is 26.4-31.5Mpa, the elongation at break is 286-310%, and it has good wear resistance, aging resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of sheath materials, in particular to a wear-resistant and aging-resistant power cable sheath material and a preparation method thereof. Background technique [0002] Wires and cables are widely used in various fields as electric energy and information transmission bodies. In order to increase the service life of the cable and ensure the normal operation of the wire and cable, a protective sheath is usually provided outside the cable to protect the cable. The commonly used cable sheath is rubber or polyethylene material, and the elasticity of the rubber sheath is relatively Good, but the weather resistance is relatively poor, and it is easy to age and crack, while the polyethylene sheath material is brittle, and its wear resistance and toughness are relatively poor, so it cannot protect the cable well. [0003] Chinese patent application number 201410072303.4 discloses a heat-resistant and anti-aging cable ...
