Problems solved by technology

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 equipment

Abstract

The invention discloses a wear-resistant cable material for large power and a preparation method thereof. The wear-resistant cable material is prepared from 15-20 parts by weight of a waste ball material, 35-45 parts by weight of EVA resin, 3-4 parts by weight of zinc stearate, 2-4 parts by weight of oligomer ester, 3-5 parts by weight of dioctyl terephthalate, 4-6 parts by weight of polyethylene wax, 10-16 parts by weight of acrylic acid-grafted polyethylene, 5-6 parts by weight of vinyl benzene, 4-6 parts by weight of polyether-ether-ketone, 4-6 parts by weight of lauryl diethanolamide, 3-4 parts by weight of quartz sand, 4-5 parts by weight of disalicylideneethylenediamine, 15-25 parts by weight of precipitated white carbon and 8-12 parts by weight of a filler. The wear-resistant cable material has good mechanical properties, wear resistance, chemical resistance and hydrolysis resistance. Through use of polyether-ether-ketone, the wear-resistant cable material does not shrink at a high temperature under high pressure.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-power wear-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 equipment. ...
