High-flexibility cable material for high power and preparation method thereof

Abstract

The invention discloses a high-flexibility cable material for high power. The high-flexibility cable material is prepared from, by weight, 1-2 parts of antiager D, 2-4 parts of nano calcium carbonate, 3-6 parts of polypropylene, 2-4 parts of petroleum wax, 2-3 parts of zinc oxide, 1-2 parts of antiager 4010, 1-2 parts of lead oxide phosphite hydrate, 3-5 parts of zinc borate, 4-5 parts of dilauryl thiodipropionate, 4-6 parts of ethylene bis stearamide, 6-8 parts of trioctyl trimellitate, 3-5 parts of sorbitan fatty acid ester, 40-50 parts of acrylic rubber, 2-4 parts of nanometer magnesia, and 8-12 parts of filler. According to the cable material, antiager D and antiager 4010 are adopted simultaneously, so that the heat resisting, antioxidation and bending, winding and fracturing resisting capacity of products are remarkably improved; meanwhile, sorbitan fatty acid ester and other materials are added, so that the cable material is high in flexibility and wide in market prospect.

Description

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