Thin-wall insulated electric wire material for automobile and preparation method of electric wire material

Abstract

The invention relates to a thin-wall insulated electric wire material for an automobile and a preparation method of the electric wire material, belonging to the technical field of materials, and solving the problem that cable wires cannot meet long-time ageing resistance, low-temperature resistance, high-temperature resistance, high physical performance, no drop during combustion, good liquid resistance and the like simultaneously in the prior art. The cable material comprises the following ingredients in parts by weight: 100 parts of matrix resin, 30-40 parts of modifier, 40-60 parts of plasticizer, 15-25 parts of filler, 50-60 parts of flame retardant, 5-10 parts of stabilizer, 1-5 parts of wear-resistant agent, and 1-5 parts of auxiliaries, wherein the plasticizer is the mixture of halogenated biphosphate compound FR-V6, dihexyl sebacate and 2,2,4-trimethyl-1,3-pentanediol di-isobutyrate in a weight ratio of (5-10): (3-6): 1. The thin-wall insulated electric wire material for the automobile disclosed by the invention is good in physical performance, resistant to long-time ageing, and low in cost.

Description

technical field [0001] The invention relates to a wire material and a preparation method thereof, in particular to a thin-wall insulating wire material for automobiles and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] With the advancement of society, people's living standards are gradually improving. Not only are automotive cables required to be safe, environmentally friendly, and energy-saving, but they also need to be resistant to high temperature, abrasion, oil, cold, and high strength. They are also required to gradually develop in the direction of lightweight, that is, thin wall. In order to achieve thin-wall insulation, new materials can be considered, and their performance can also be improved by modifying materials. Once the thin wall is realized, it is necessary to improve the physical properties of the material. The reason is that the thin wall increases the surface area ratio per unit volume, which ...
