Abstract

The invention provides a preparation method of cable material for a new energy automobile. The preparation method comprises the following steps: (I) preparing 1-methallyl-2-(2-hydroxyl-5-methyl phenyl) benzothiazole, quaternary ammonium salt-15 and an acrylonitrile copolymer; (II) carrying out polycondensation on 4,4'-diamino stilbene-2,2'-disulfonic acid, 9-fluorenone-2,7-dicarboxylic acid; and (III) preparing the cable material for the new energy automobile. The invention also discloses the cable material for the new energy automobile prepared with the preparation method. The preparation method disclosed by the invention is simple and feasible, low in equipment dependency, unharsh in reaction condition, low in price and suitable for scaled production. The prepared cable material for thenew energy automobile has the characteristics of being low in manufacturing cost, oil-resistant, wear-resistant and flame-retardant, and has the advantages of being excellent in aging resistance, weather resistance and tear resistance, small in environmental influence, good in performance stability and long in service life.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a cable material for new energy vehicles and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, cars, as one of the tools for people's transportation, have brought great convenience to people's lives, but at the same time they have also caused threats to the ecological environment and people's health. At this stage, countries all over the world are becoming more and more strict on automobile exhaust emission standards and people's understanding of environmental issues and improving their own health. Solving the pollution caused by automobile exhaust emissions has become a problem that many automobile companies have to face. It is precisely In this situation, new energy vehicles represented by electric vehicles have emerged as the times require, and have attracted the attenti...
