Nontoxic and odorless cable material for large power and preparation method thereof

Abstract

The invention discloses a nontoxic and odorless cable material for large power. The nontoxic and odorless cable material is prepared from 3-5 parts by weight of paraffin, 2-4 parts by weight of high density polyethylene, 6-8 parts by weight of low density polyethylene, 12-18 parts by weight of high strength polypropylene resin, 2-3 parts by weight of stearic acid, 4-5 parts by weight of alkylphenol polyoxyethylene, 35-55 parts by weight of butyl rubber, 3-5 parts by weight of zinc borate, 2-4 parts by weight of antimonous oxide, 3-5 parts by weight of tris[2,4-di-tert-butylphenyl]phosphite, 4-6 parts by weight of dicumyl peroxide, 4-7 parts by weight of ethyl acrylate, 2-3 parts by weight of poly(diallyldimethylammonium chloride), 3-4 parts by weight of barium sulfate and 8-12 parts by weight of fillers. The nontoxic and odorless cable material utilizes nontoxic and odorless raw materials and is biodegradable easily. Through use of multiple fillers such as alkylphenol polyoxyethylene and poly(diallyldimethylammonium chloride), the nontoxic and odorless cable material has excellent mechanical properties and chemical resistance and is suitable for being used under multiple conditions.

Description

Technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power non-toxic and odorless 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 equipme...

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
