Abstract

The invention discloses a wear-resisting anti-aging power cable sheath material. The wear-resisting anti-aging power cable sheath material is prepared from, by weight, 30-40 parts of nitrile rubber, 20-30 parts of polyvinyl chloride, 20-30 parts of phenolic resin, 10-18 parts of carbon fiber, 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-xylene ursol, 1-2 parts of stearic acid, 10-15 parts of a fire retardant, 3-5 parts of paraffin and 1-1.5 parts of an anti-aging agent. The tensile strength of the cable sheath material is 26.4-31.5 Mpa, the elongation at break is 286%-310%, and the wear-resisting anti-aging power cable sheath material is good in wear resistance and aging resistance and long in 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 ...
