Abstract

The invention discloses a high-strength and abrasion-proof cable sheath material, which comprises the following components in parts by weight: 15 to 30 parts of nitrile rubber, 40 to 60 parts of chloroprene rubber, 10 to 15 parts of chlorinated polyethylene, 1.5 to 4 parts of zinc oxide, 1.5 to 4 parts of magnesium oxide, 0.8 to 1.5 parts of N,N'-m-phenylene dimaleimide, 0.5 to 2 parts of calcium stearate, 0.8 to 2.5 parts of accelerator 4010NA, 1.8 to 3 parts of paraffin, 35 to 44 parts of white carbon black, 20 to 25 parts of superfine talc powder, 12 to 14 parts of active kaolin, 2 to 4 parts of dicumyl peroxide, 0.7 to 1.4 parts of diallyl isocyanate, 2 to 4 parts of antimony trioxide and 4 to 6 parts of magnesium hydroxide. The high-strength and abrasion-proof cable sheath material is high in tear resistance and abrasion-proof performance and long in service life, and has good flame-retardant effects.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a high-strength wear-resistant cable sheath material. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of wires, and each group is twisted with at least two wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulated The sheath layer, in order to protect the urban and rural living and investment environment, reduce the overhead power cable transmission line to achieve the purpose of beautifying the city, the power cable transmission line has been buried from the overhead, the tear strength and resistance of the cable outer sheath to the underground of the cable Abrasion performance has high requirements. With the extension of cable service time and the limitation of cable storage space, its heat dissipation is poor, ...
