[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 inconvenience to actual use and even threaten people's life and property safety. Therefore, it is urgent to change the original formula and improve material properties to adapt to automotive electronic devices. Diverse needs of the market

Abstract
The invention relates to an insulation material for a wire harness, and in particular relates to a modified polyvinyl chloride insulation material for an automobile wire harness. The insulation material comprises the following raw materials in parts by weight: 23 to 25 parts of polyvinyl chloride, 6 to 9 parts of 1,4-butanediol, 12 to 14 parts of polyolefin elastomer (POE), 12 to 15 parts of polyoxymethylene, 12 to 13 parts of naphthenic oil, 3 to 4 parts of petroleum resin, 10 to 12 parts of nylon PA66, 6 to 9 parts of magnesium hydrate, 18 to 22 parts of chlorosulfonated polyethylene, 24 to 28 parts of carbon black N550, 2 to 3 parts of calcium metasilicate, 18 to 22 parts of tributyl citrate and 14 to 16 parts of addition agent. The insulation material is prepared by combining the advantages of the polyvinyl chloride, the polyolefin elastomer (POE), the polyoxymethylene and the other raw materials, so that the performance of the traditional polyvinyl chloride blending material is improved. The prepared insulation material is firm, flexible, weather-proof, aging-proof, ozone-proof, resistant to chemical corrosion and long in service life. Thus, the prepared insulation material can be widely used for manufacturing the insulating sheaths of the wire harnesses at all parts of an automobile, terminals, binding materials and the like, thereby having a wide market demand prospect.
