Wear-resistant cable sheath material

Abstract

The invention discloses a wear-resistant cable sheath material. The wear-resistant cable sheath material is prepared from the following raw materials in parts by weight: 50-80 parts of polyvinyl chloride resin, 20-40 parts of a chloroethylene-vinyl acetate copolymer, 10-15 parts of polyvinylidene fluoride, 10-15 parts of natural rubber, 5-10 parts of butyronitrile rubber, 5-8 parts of butadiene styrene rubber, 3-9 parts of cis-butadiene rubber, 10-12 parts of glass fibers, 8-14 parts of carboxymethyl cellulose, 2-6 parts of carbon black, 1-3 parts of white carbon black, 1-3 parts of talcum powder, 0.5-2 parts of zinc oxide, 0.5-2 parts of magnesium oxide, 4-6 parts of stearic acid, 5-8 parts of nano calcium carbonate, 5-8 parts of nano silicon powder, 5-7 parts of nano Xuancheng stone and 6-12 parts of an insect-proof and ratproof auxiliary. The wear-resistant cable sheath material disclosed by the invention has the advantages that the polyvinyl chloride resin, a chloroethylene-vinyl acetate copolymer, polyvinylidene fluoride, natural rubber, butyronitrile rubber, butadiene styrene rubber and cis-butadiene rubber mutually coordinate, and then other raw materials are supplemented, so that the finished product has stronger wear resistance and bite-proof performance, and service life is obviously prolonged.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a wear-resistant cable sheathing material. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. [0003] A cable is usually a rope-like cable twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Highly insulating cable jacket. The cable has the characteristics of internal electrification and external insulation. [0004] After entering the modern society, due to the shortage of urban land, heavy traffic pressure, city appearance construction and other reasons, large cities generally adopt underground cable transmission. Compared with overhead cables, underground cables have the advantages of small footprint, reliable power transmission, and strong anti-interference abili...

Problems solved by technology

[0005] However, the wear resistance of the existing cables is poor, and they are prone to deformation and damage to varying degrees after friction with the ground during transportation and laying. At the same time, underground cables are often bitten by insects and rats and other organisms, resulting in circuit failures.
