Improved smokeless flame-retardant cable material

Abstract

An improved smokeless flame-retardant cable material is prepared from, by weight, 9-15 parts of linear high-density polyethylene, 5-9 parts of magnesium hydroxide, 6-8 parts of vulcanizing agents, 6-10 parts of metallocene linear low-density polyethylene, 4-10 parts of polymethylphenyl siloxane fluid, 3-7 parts of white carbon black, 4-8 parts of mica powder, 9-13 parts of ethylene tetrafluoroethylene, 8-12 parts of ethylene-vinyl acetate, 4-6 parts of fumed white carbon black, 3-9 parts of oxidized polyethylene wax, 1-3 parts of ziram, 2-5 parts of isopropyl tri(dioctylpyrophosphate) titanate and 6-11 parts of PVC resin. The improved smokeless flame-retardant cable material has the advantages that the smokeless flame-retardant performance is good, the fire behavior can be delayed, and economic losses and casualties are reduced.

Description

technical field [0001] The invention relates to an improved smokeless flame retardant cable material. Background technique [0002] With the rapid growth of wire and cable applications and rapid economic development, the requirements for the quality and performance of wire and cable materials in various fields are increasing. The cable is required to have good flame retardancy and high temperature resistance, and at the same time, it will not bring harm to the environment. Flame-retardant cable materials are cable materials that are more and more widely used. Although general flame-retardant cable materials improve the cable sheath Excellent flame retardant performance, but this kind of cable sheath will produce a lot of toxic gas and pollution when burned. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide an improved smokeless flame retardant cable material, which has good smoke...
