High-strength automotive wire cable material

Abstract

The invention discloses a high-strength automotive wire cable material. The high-strength automotive wire cable material is prepared from the following components in parts by weight: 100 parts of SG3 type PVC (poly vinyl chloride) resin, 30 parts of rare earth calcium-zinc compound stabilizer, 3 parts of dioctyl terephthalate, 12 parts of nano calcium carbonate, 12 parts of commercial calcium-zinc stabilizer, 1.2 parts of polyethylene wax, 3 parts of ACR impact resistance modifier, 0.2 part of bisphenol A, 2 parts of nano barium sulfate and 0.6 part of silicone powder; the silicone powder is nanocrystalline silicon dioxide powder coated with silicone; the rare earth calcium-zinc compound stabilizer is prepared from 5 parts by weight of yttrium oxide, 1 part by weight of indium oxide, 15 parts by weight of tartaric acid, 3 parts by weight of sodium potassium tartrate, 32 parts by weight of calcium silicate, 38 parts by weight of zinc stearate, 2 parts by weight of phosphorous acid and 10 parts by weight of silicone powder. Heat-resistant grade of the PVC cable material is 105 DEG C, the cable material still has good processability under high-speed processing condition, and the obtained cable has excellent abrasion resistance performance.

Description

technical field [0001] The invention relates to the technical field of insulating cable materials, more specifically, the invention relates to a high-strength automobile wire and cable material. 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 ...

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.
