Easily processable cable material for large power and preparation method thereof

Abstract

The invention discloses an easily processable cable material for large power and a preparation method thereof. The easily processable cable material is prepared from 3-4 parts by weight of paraffin, 2-4 parts by weight of nanometer barium sulfate, 6-8 parts by weight of an ethene/vinyl acetate copolymer, 3-5 parts by weight of bis(P,P-bis-ethylhexyldiphosphato)ethanediolatotitanate, 2-4 parts by weight of expandable graphite, 2-3 parts by weight of active aluminum hydroxide, 40-50 parts by weight of high strength polyethylene resin, 4-5 parts by weight of benzoyl peroxide, 2-3 parts by weight of an antistatic agent SN, 3-5 parts by weight of limestone, 4-6 parts by weight of fatty acid amide, 4-5 parts by weight of wicker fibers, 2-3 parts by weight of nanometer bentonite, 1-2 parts by weight of an antiager DNP and 8-12 parts by weight of a filler. The easily processable cable material has good processing performances and no peculiar smell. Through use of the bis(P,P-bis-ethylhexyldiphosphato)ethanediolatotitanate, cable material impact resistance and fluidity are improved.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power easy-to-process 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 equip...
