Abstract

The invention discloses a polyvinyl chloride insulating layer for an automotive electric wire. The polyvinyl chloride insulating layer 2 is wrapped on the outer surface of a cable core 1, and the polyvinyl chloride insulating layer 2 is obtained by processing the following components in part by weight: 100 parts of polyvinyl chloride resin, 24 to 26 parts of trioctyl trimellitate, 10 to 12 parts of fine dioctyl terephthalate, 4.5 to 5.5 parts of epoxy soybean oil, 18 to 20 parts of calcium carbonate, 6.5 to 7.5 parts of calcium-zinc composite stabilizer (105 DEG C), 1 to 1.5 parts of high-melting polyethylene wax, 0.14 to 0.16 part of phenolic antioxidant, 0.5 to 2 parts of acrylate resin, 2.8 to 3.2 parts of barium sulfate, and 1.4 to 1.6 parts of silicone powder, wherein the melting point of the high-melting polyethylene wax is more than 105 DEG C. The polyvinyl chloride insulating layer can effectively reduce the odor, meanwhile, has excellent abrasion resistance and heat resistance, and keeps good surface and mechanical performance at a high processing speed.

Description

technical field [0001] The invention relates to an insulating layer of electric wires for automobiles, in particular to a polyvinyl chloride insulating layer applied to electric wires of automobiles. Background technique [0002] Usually, the production method of polyvinyl chloride cable materials for automobile wires is based on polyvinyl chloride resin, adding plasticizers, stabilizers and processing aids, and processed by special mixing equipment, although it can meet the basic needs of automobile line production , but there are problems of strong odor, poor scraping performance and unsatisfactory processing performance. Due to the special use position of the automobile wire, the mutual friction between the wire and the wire cannot be avoided during the operation of the automobile. Once the plastic sheath is worn out, it will directly lead to a short circuit and cause traffic accidents. In addition, the car compartment is a relatively closed space. The supporting items u...
