Abstract

The invention discloses heat-resisting and wear-resisting PVC (Polyvinyl Chloride) plastic. The heat-resisting and wear-resisting PVC plastic is prepared from the following materials in parts by weight: 60 to 70 parts of polyvinyl chloride, 18 to 22 parts of a high molecular polymer, 30 to 35 parts of a plasticizer, 2 to 4 parts of a stabilizer, 6 to 8 parts of a filler, 3 to 5 parts of an antioxidant, 1 to 3 parts of a lubricant and 0.5 to 1 part of a modifying agent. According to the heat-resisting and wear-resisting PVC plastic disclosed by the invention, chemical components are optimized,so an inner structure of the PVC plastic is improved from the microcosmic aspect; and the heat-resisting and wear-resisting PVC plastic has excellent heat-resisting performance and anti-abrasion performance.

Description

technical field [0001] The invention relates to a plastic, in particular to a heat-resistant and wear-resistant PVC plastic. 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 car wires are required to be heat-resistant, cold-resistant, wear-resistant, odo...
