Solvent-resistant cable material for large power and preparation method thereof

Abstract

The invention discloses a solvent-resistant cable material for large power and a preparation method thereof. The solvent-resistant cable material comprises, by weight, 1-2 parts of an antiager MB, 3-5 parts of epoxidized soybean oil, 4-6 parts of ethylene dimethacrylate, 30-50 parts of nitrile rubber, 2-4 parts of an ethene-propylene-butylene ternary copolymer, 2-4 parts of light calcium carbonate, 3-5 parts of zinc stearate, 2-5 parts of magnesium hydroxide, 3-4 parts of tetra[beta-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid]pentaerythritol, 2-4 parts of calcined clay, 3-6 parts of polyethylene wax, 5-8 parts of diisodecyl phthalate, 2-4 parts of sodium pyrosulfite, 15-25 parts of isoprene rubber and a filler. The preparation method has a reasonable design, can be operated simply, and has a high raw material utilization rate. The solvent-resistant cable material has the characteristics of heat resistance, weatherability and solvent resistance and excellent wear resistance and can be widely used in the field of power cables.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power solvent-resistant 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 equ...
