Problems solved by technology

[0002] At present, the heat resistance of many cables is not very ideal. During use, the cables will be softened due to excessive heat generation. In addition, the cables will be exposed to wind, sun and rain for a long time during use. Various influences, so that the insulation layer and sheath layer in the cable will age, and finally crack or even fall off, thus affecting the safety performance of the cable; in addition, the aging and cracking of the insulation layer and sheath layer will also lead to a decrease in the strength of the cable , making the cable brittle

Abstract

The invention discloses a heatproof high-strength cable which comprises a conductor, an insulating layer, a high-temperature-resistant layer and an outer sheath insulating layer which are made of a modified polyvinyl chloride material. The modified polyvinyl chloride material comprises polyvinyl chloride, nylon, maleic anhydride grafted polyphenyl ether, bisphenol-A polycarbonate, stearic acid pentaerythritol ester, trioctyl trimellitate, stearic acid, isopropyl phenyl diphenyl phosphate, calcined kaolin, modified nano-calcium carbonate, maleic acid modified hydrotalcite, modified graphene oxide, carbon nanofibers, diethyl dithiocarbamate neodymium, calcium adipate, glyzinc, beta-diketone, pentaerythritol, ethylene-vinyl alcohol and antioxidant. The heatproof high-strength cable is high in intensity, good in heat resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a heat-resistant high-strength cable. Background technique [0002] At present, the heat resistance of many cables is not very ideal. During use, the cables will be softened due to excessive heat generation. In addition, the cables will be exposed to wind, sun and rain for a long time during use. Various influences, so that the insulation layer and sheath layer in the cable will age, and finally crack or even fall off, thus affecting the safety performance of the cable; in addition, the aging and cracking of the insulation layer and sheath layer will also lead to a decrease in the strength of the cable , making the cable brittle. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a heat-resistant high-strength cable, which has high strength, good heat resistance and long service life. [0004] A heat-...
