Abstract

Disclosed in the invention is an anti-aging flame-retardant power cable. The cable comprises conductors. A plurality of wires are twisted mutually to form a bundle and then a wrapping layer and an insulating layer coats the outside of the bundle successively to form one conductor. The gap among the N conductors is filled with flame-retardant filling materials to form a cable core. Besides, an aluminum-plastic composite isolation layer and a fireproof sheath layer coats the outside of the cable core successively. The fireproof sheath layer is prepared by using a modified natural rubber composite material, wherein raw materials of the modified natural rubber composite material consist of natural rubber, terpolymer EP rubber, an ethylene-butene elastomer, a polyacrylonitrile fiber, stearic acid, zinc oxide, dicumyl peroxide, sulphur, active calcium silicate, calcined attapulgite, modified montmorillonite, graphene oxide, expansible graphite, ammonium polyphosphate, diethylphosphinic acid aluminium salt, an accelerant, an anti-aging agent, triphenyl phosphate, hexakis (4-formacylphenoxy) cyclotriphosphazene, pentaerythritol, perfluorooctanamide, octadecylamine, and bis(diisopropyl)thiophosphoryl disulfide.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an aging-resistant and flame-retardant power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. They are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. With the development of the economy, the places where power cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of power cables, such as tensile strength, service temperature, aging resistance, flame retardancy and other indicators. There are strict requirements, and the continuous improvement of the comprehensive performance of power cables is an urgent need for economic and social development. Most of the existing power cables have problems suc...
