Abstract

The invention discloses a high-strength, abrasion-resistant and tear-resistant cable. The cable comprises a cable core, wherein an inner sheath covers the cable core, and a shielding layer, a wrapping layer and an outer sheath sequentially cover the inner sheath; the outer sheath comprises raw materials in parts by weight as follows: 50-55 parts of butadiene styrene rubber, 22-25 parts of natural rubber, 20-22 parts of a prefabricated aramid pulp sizing material, 14-18 parts of chloroprene rubber, 0.7-1.1 parts of sulphur powder, 1.8-2.2 parts of an accelerant AA, 2.3-2.6 parts of an accelerant MZ, 14-17 parts of barite powder, 26-29 parts of carbon black N234, 7-10 parts of nano-cellulose whiskers, 8-10 parts of calcite powder, 6-9 parts of kieselguhr, 5-8 parts of aluminum silicate, 2.8-3.2 parts of a mono-alkoxy pyrophosphate type titanate coupling agent, 2.6-3.2 parts of coconut oil, 1.4-1.8 parts of a plasticizer DCHP, 5-7 parts of octyl epoxy stearate, 1.6-2.4 parts of an anti-aging agent H and 1.8-2.5 parts of an anti-aging agent DFC-34.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength wear-resistant and tear-resistant cable and a method for preparing an outer sheath thereof. Background technique [0002] Electricity has become an indispensable element in people's production and life, and the cables for power transmission are mainly protected by externally wrapped cable materials. The application of cable materials often has to face harsh outdoor environments, which puts forward higher requirements on the strength of cable materials, and as people pay more and more attention to safety in production, wear resistance and tear resistance have also become the choice of cable manufacturers for cable manufacturers. An important indicator of material. [0003] Aramid pulp is a highly dispersed fibrillated aramid fiber. Due to the chemical structure of para-aramid fiber, the retained para-aramid fiber has properties such as high modulus, high strength, ...
