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 relates to a polyvinyl chloride (PVC) cable material for an automobile data transmission wire. The PVC material comprises the components based on parts by weight: 100 parts of SG3 type PVC resin, 25-30 parts of plasticizer 1, 3-5 parts of plasticizer 2, 10-12 parts of calcium carbonate, 8-12 parts of stabilizer, 0.8-1.2 parts of polyethylene wax, 2-4 parts of ACR impact modifier, 0.1-0.5 part of antioxidant, 2-3 parts of nano barium sulfate and 0.3-0.8 part of silicone powder, wherein the plasticizer 1 comprises one or two selected from trioctyl trimellitate or purified terephthalic acid dioctyl ester; the plasticizer 2 comprises one or two selected from epoxidized soybean oil and terephthalic acid dioctyl ester; and the silicone powder is silica powder treated by silicone. The PVC cable material has the temperature classification of 105 DEG C, thus having good processability under the condition of high-speed processing; and the obtained cable has excellent abrasion resistance and mechanical property, and the odor can be eliminated.

Description

technical field [0001] The invention relates to the technical field of insulating cable materials, more specifically, 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 retardancy, corrosion resistance, good electrical insulation, good processing performance and low price, so it is widely used in the cable material industry. Usually, automotive wires are usually made of polyvinyl chloride resin as the base material, adding plasticizers, stabilizers and processing aids, and processed by special mixing equipment. Automobile wires and cables are different from ordinary wires and cables, and are specially designed for the needs of automobiles. Since the interior of the car is a very complicated small environment, there are various complex conditions such as vibration, friction, oil pollution, high heat, cold and electromagnetic radiation, so the...
