Modified heat-resistant and flame-retardant polyvinyl chloride insulating material for wire harnesses of automobile

Abstract

The invention relates to an insulating material for wire harnesses and particularly relates to a modified heat-resistant and flame-retardant polyvinyl chloride insulating material for wire harnesses of an automobile. The material comprises the following raw materials in parts by weight: 32-35 parts of SG (Specific Gravity)-4 polyvinyl chloride resin, 4-5 parts of high-glue ABS (Acrylonitrile Butadiene Styrene) powder, 12-15 parts of EVA (Ethylene-Vinyl Acetate), 4-5 parts of trioctyl trimellate, 2-3 parts of calcium-zinc compound stabilizer, 5-7 parts of methyl methacrylate, 3-4 parts of ethyl acrylate, 20-24 parts of calcium bentonite, 2-4 parts of polyacrylamide, 4-5 parts of stearic acid, 2-4 parts of castor oil, 26-28 parts of dioctyl phthalate, 1-2 parts of zinc oxide, 3-4 parts of beta-myrcene, 3-5 parts of cobalt aluminate and 14-16 parts of auxiliaries. The insulating material combines the advantages of the raw materials such as polyvinyl chloride resin, high-glue ABS powder, EVA and the like, and the prepared material is firm, durable, resistant to chemical corrosion and high-temperature exposure, long in service life, safe, reliable, capable of being widely applied to the preparation of insulating sheathes, terminals, wrapping materials and the like of the wire harnesses on all parts of the automobile and wide in market requirement prospect.

Description

technical field [0001] The invention relates to an insulating material for wiring harnesses, in particular to a modified polyvinyl chloride insulating material for heat-resistant and flame-retardant automobile wiring harnesses and a preparation method thereof. Background technique [0002] The automobile wiring harness is the main body of the automobile circuit network. It connects the electronic components of various parts of the automobile. The quality of the wiring harness. The automotive wiring harness materials mainly include wires, terminals, sheaths, tapes, etc. In practical applications, the wiring harness materials of suitable materials should be selected according to the working environment and performance requirements of the wiring harnesses of different parts of the car. Traditional wiring harnesses use insulating materials. There are many problems such as poor flame retardancy, easy deformation at high temperature, and short service life, which bring a lot of in...
