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 high-power high-stability cable material which is prepared from the following raw materials in parts by weight: 6-8 parts of oxidized polyethylene wax, 15-25 parts of PVC (polyvinyl chloride) resin, 3-4 parts of epoxy soybean oil, 3-5 parts of soluble polytetrafluoroethylene, 2-4 parts of nano titanium dioxide, 5-7 parts of ethylene-octylene copolymer, 3-4 parts of carbon fiber, 2-3 parts of benzotriazole, 4-5 parts of red phosphorus, 2-3 parts of nano graphite, 1-2 parts of accelerator CZ, 45-55 parts of nitrile silicone rubber, 6-7 parts of nano calcium carbonate, 2-5 parts of maleic anhydride grafted polypropylene and 8-12 parts of filler. The cable material has favorable chemical property stability, physical and mechanical properties, electrical insulation properties, aging resistance and flame retardancy, and can satisfy the demands for cable manufacturing industry.

Description

Technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power high-stability 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, the use of high-power equipment is increasing, which puts forward higher requirements for the performance of cables. The withstand power of the cable has a linear relationship with the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is subject to the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor. 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. Therefo...
