Abstract

The invention discloses a wear-resistant and bending-resistant cable outer sheath. The cable outer sheath comprises, by weight, 50-88 parts of polyurethane resin, 43-59 parts of nitrile butadiene rubber, 20-30 parts of chloroprene rubber, 20-40 parts of an acrylic acid emulsion, 3-10 parts of organosilicon, 20-30 parts of diatomite, 11-14 parts of zinc borate, 5-10 parts of precipitated calcium carbonate, 3-7 parts of crocidolite, 8-15 parts of calcined clay, 6-12 parts of ethyl acrylate, 4-7 parts of pine tar and 2-5 parts of a waterproof agent. The cable outer sheath improves the wear resistance of the sheath, and improves the heat dissipation efficiency of rubber, so the high temperature resistance and the heat conduction performance of the sheath material are improved; and additionally, the wear-resistant and bending-resistant cable outer sheath has the advantages of good ageing resistance, low production cost and long service life.

Description

technical field [0001] The invention relates to the field of cables, in particular to an outer sheath of an abrasion-resistant and bending-resistant cable. Background technique [0002] With the development of social economy, cables are widely used in aerospace, electronics, machinery and other fields. According to the different working environment of the cable, there are different requirements for the performance of the cable. Wires and cables have a wide range of uses, and their performance requirements vary greatly in different use occasions. The sheath materials of most cables must not only have high insulation resistance, withstand voltage strength or low dielectric loss, but also have good physical and mechanical properties, such as tensile resistance, bending resistance, vibration resistance, torsion resistance, etc. ; And due to the need to adapt to different use environments and occasions, there are requirements for tear resistance, high and low temperature resist...
