Abstract

The invention discloses an automobile electric wire with fire-resistant and flame-retardant performance. The automobile electric wire is characterized by consisting of the following components in parts by weight: 60 to 70 parts of polyethylene rubber, 5 to 10 parts of a peroxide crosslinking agent, 3 to 5 parts of flame-retardant oil, 3 to 8 parts of silicon dioxide, 2 to 5 parts of kaolin, 6 to 8 parts of fossil meal and 5 to 10 parts of an anti-ageing agent. A high-temperature-resistant flame-retardant insulating material provided by the invention can work for a long time at 125 DEG C, even 150 DEG C, has high ageing resistance, can resist the low temperature of -40 DEG C, and has excellent wear resistance, flame resistance, oil resistance and mildew resistance. A product can meet the T3 and T4 standard requirements in DINISO6722 after being manufactured into an automobile wire, thereby being a novel automobile wire material. In addition, the electric wire disclosed by the invention is simple in extrusion process and low in cost.

Description

technical field

[0001] The invention relates to a cable insulation material, in particular to an automobile wire with fire-resistant and flame-retardant properties. Background technique

[0002] According to the requirements of the application environment, automotive wires need to have properties such as heat resistance, flame retardancy, abrasion resistance, oil resistance, and mold resistance. Depending on the environment and location, automotive cables are classified into various temperature classes. At this stage, according to the development trend of the market and the needs of customers, the wire products with a temperature of 105 ℃ and below are generally insulated with PVC, and the automotive wires with a grade above 105 ℃ are insulated with radiation cross-linked polyolefin materials. Compared with PVC, the insulation performance, chemical performance and heat resistance performance of polyolefin materials have been significantly improved. However, the irradiation...
