Abstract

The invention discloses an environment-friendly abrasion-resistant cable sheath material. The environment-friendly abrasion-resistant cable sheath material comprises, by weight, 40-60 parts of chloroprene rubber, 30-50 parts of ethylene-propylene-diene-monomer rubber, 5-10 parts of magnesium hydroxide, 10-15 parts of triethyl citrate, 8-12 parts of polysulfone resin, 12-16 parts of polyimide resin, 3-8 parts of zinc isocaprylic acid, 5-9 parts of calcium cyclamate, 2-6 parts of strontium thioglycollic acid, 5-10 parts of 1, 3:2, 4-di-p-methylbenyliedene sorbitol, 2-8 parts of microcrystalline celluloses and 1-6 parts of sulfur concentrate powder. The environment-friendly abrasion-resistant cable sheath material has the advantages of environmental friendliness and excellent abrasion-resistant performance.

Description

technical field [0001] The invention belongs to the field of cable sheath materials, and in particular relates to an environment-friendly wear-resistant cable sheath material and a preparation method thereof. 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 jacket layer. The cable sheath is an important part of the cable, which protects the cable by isolating the inner conductor from water, air and other media to avoid leakage. Nowadays, in order to further optimize and beautify the living environment in urban and rural areas, power cable transmission lines have been gradually buried underground, so cable sheath materials with good wear resistance are required. However, in the existing cable sheath materials, the...
