AI Technical Summary

Problems solved by technology

Under certain high temperature conditions, the performance of the cable material will change in one way or another, and even lose its use value. Therefore, if the protective sheath material does not have good heat resistance, even if other properties are better Well, also not up to good practicality

Abstract

The invention discloses a heat-resistant high-strength cable sheath material. The material is prepared from, by weight, 50-70 parts of SBR-1712 emulsion polymerized butadiene styrene rubber, 30-50 parts of NBR-3604 butadiene-acrylonitrile rubber, 1-2 parts of N-tertiary butyl-2-benzothiazole sulfenamide, 2-4 parts of N, N'-m-phenylene dimaleimide, 1-2 parts of stearic acid, 0.5-1 part of zinc dibutyl dithiocarbamate, 2-6 parts of paraffin, 0.5-1.5 parts of an anti-aging agent, 3-8 parts of hydroxyapatite powder, 2-5 parts of white oil, 15-25 parts of semi-reinforced carbon black and 10-20 parts of light calcium carbonate. Meanwhile, the invention discloses a preparation method of the heat-resistant high-strength cable sheath material. The heat-resistant high-strength cable sheath material is excellent in processability, heat resistance and mechanical strength, simple in processing technology, great in practicability and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of cable processing materials, in particular to a heat-resistant high-strength sheath material for external use of cables and a preparation method thereof. Background technique [0002] Wire and cable are the carriers of power transmission and information transmission, and are widely used in industrial and civil electrical facilities. Wires and cables are used in different environments or occasions and have different requirements, which puts forward higher requirements for the cable sheath covering the outside of the cable. The main function of the cable sheath is to mechanically and electrically protect the transmission cable from various conditions that will cause it to lose its transmission function. The cable jacket must fulfill this protective function during installation, splicing and throughout the service life of the cable. During the service life of the cable, the sheath must protect the cable cor...
