Problems solved by technology

Most of the reports on polyvinyl chloride wires for vehicles are non-crosslinked ordinary cable materials with a heat resistance level below 90°C, and there are also reports of polyvinyl chloride cable materials for vehicles using radiation crosslinking. PVC cable materials above 105°C are generally used The way of cross-linking, with trimethoxypropane trimethacrylate (TMPTMA) as cross-linking agent, with Co 60 Gamma ray is used as the radiation source to achieve better results, but the processed wire needs to be cross-linked by γ ray irradiation in a place with irradiation conditions, which is troublesome

Abstract

The invention relates to a cord-cable polyvinyl chloride (PVC) plastic for an automobile, which is formed by chemical crosslinking and mainly comprises PVC, a plasticizing agent, a heat stabilizer, a lubricating agent, an antioxidant, stuffing, a crosslinking agent, an evocating agent, a crosslinking assistant agent and an abrasion resistance modifier. The polymer crosslinking plastic material has the advantages of good abrasion resistance, excellent mechanical property, good high temperature resistance (the heat resistant grade can reach 120 DEG C and the low temperature can reach 40 DEG C below zero), over 70 percent of tensile strength and elongation at break under the ageing condition at 150 DEG C for 168 hours, little weight loss and simple processing technique.

Description

technical field [0001] The invention relates to a soft polyvinyl chloride plastic for electric wires and cables for automobiles and a preparation method thereof. Background technique [0002] Wires and cables are one of the important components of automotive electrical appliances. Automobile wires 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, ozone, oil pollution, high heat, cold and electromagnetic radiation, etc., requiring automotive wires to be heat-resistant, cold-resistant, wear-resistant, oil-resistant and anti-interference. At present, most of the materials used in automobile wires are polyvinyl chloride and cross-linked polyethylene. Most of the reports on polyvinyl chloride wires for vehicles are non-crosslinked ordinary cable materials with a heat resistance level below 9...
