Abstract

The invention discloses a high-fire-resistance cable material for high power. The high-fire-resistance cable material comprises, by weight, 3-5 parts of calcium carbonate, 6-8 parts of ethylene-octene copolymer, 25-35 parts of powder acrylonitrile-butadiene rubber, 20-30 parts of ethylene-octene copolymer resin, 30-40 parts of fluoride rubber, 4-5 parts of polyethylene glycol, 3-5 parts of ethylene-ethyl acrylate copolymer, 2-4 parts of kaolin, 2-3 parts of hydrazide, 3-4 parts of dibenzoyl peroxide, 1-3 parts of 2-methyl methacrylate, 2-3 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 1-2 parts of zinc oxide, 2-4 parts of tert-butyl peroxybenzoate and 8-12 parts of filler. The cable material has the good machining performance, and the added tetrafluoroethylene-hexafluoropropylene copolymer enables the product to have excellent electrical characteristics, excellent fire resistance and excellent high temperature and low temperature resistance.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power high flame-retardant cable material and a preparation method thereof. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-power ...
