Problems solved by technology
However, the wear resistance of the cable material in the above-mentioned patents needs to be further improved.
In recent years, with the development of irradiation technology, the development of cross-linked cable materials has been promoted. Irradiation cross-linked PVC insulation materials can significantly improve the wear resistance of materials, but the process is complicated and the cost is high.

Abstract
The invention discloses a modified polyvinyl chloride (PVC) cable material for data cables. The cable material is prepared from the following raw materials in parts by weight: 100 parts of SG3 PVC resin, 25 parts of trioctyl trimellitate, 2 parts of epoxy soybean oil, 3 parts of dioctyl terephthalate, 10 parts of nano calcium carbonate, 8 parts of commercially available calcium zinc stabilizer, 0.8 part of polyethylene wax, 4 parts of ACR impact modifier, 0.2 part of antioxidant, 2 parts of nano barium sulfate and 0.6 part of silicone powder. The silicone powder is nanocrystal silicon dioxide powder subjected to silicone powder coating treatment and is prepared from 0.2 part by weight of silicone powder and 0.4 part by weight of silicon dioxide powder. The temperature classification of the PVC cable material is 105 DEG C; the PVC cable material still has favorable processability under high-speed working conditions; and the obtained cable has the advantages of excellent friction resistance, excellent mechanical properties and no peculiar smell.
Description
technical field [0001] The invention relates to the technical field of insulating cable materials, and more particularly, the invention relates to a PVC cable material for data transmission automobile wires. Background technique [0002] Polyvinyl chloride material has good rigidity, high strength, flame retardant, corrosion resistance, good electrical insulation; and good processing performance, low price, so it has a wide range of applications in the cable material industry. Usually automobile wires are usually made of polyvinyl chloride resin as the base material, adding plasticizers, stabilizers and processing aids, and processed by special mixing equipment. Different from ordinary wires and cables, automobile wires and cables are specially designed for the needs of automobiles. Because the inside of the car is a very complex small environment, there are various complex conditions such as vibration, friction, oil pollution, high heat, cold and electromagnetic radiation,...
