Peculiar-smell-free heatproof cable material for large power and preparation method thereof

Abstract

The invention discloses a peculiar-smell-free heatproof cable material for large power. The material is prepared from the following raw materials by weight: 50 to 60 parts of PVC resin type SG3, 2 to 4 parts of dolomite dust, 3 to 5 parts of (glycidyloxypropyl)trimethoxysilane, 5 to 6 parts of pentaerythritol, 3 to 5 parts of dicumyl peroxide, 4 to 5 parts of N,N'-di(beta-naphthyl)p-phenylenediamine, 2 to 4 parts of wollastonite, 3 to 4 parts of heavy calcium, 2 to 4 parts of silicone, 4 to 5 parts of ethylene-octylene copolymer, 2 to 3 parts of bis(t-butylperoxide)diisopropylbenzene, 3 to 5 parts of diphenylmethane bimaleimide, 2 to 4 parts of polyisobutylene, 2 to 3 parts of barium chromate and 8 to 12 parts of a filler. The cable material provided by the invention employs simple raw materials, is free of irritant stink, has excellent heat resistance and much lower smoke density compared with a common cable material, and is suitable for large-scale application.

Description

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