Abstract

The invention discloses a low-temperature-resistant halogen-free flame-retardant polyvinyl chloride cable material used for automobiles and a preparation method of the low-temperature-resistant halogen-free flame-retardant polyvinyl chloride cable material. The low-temperature-resistant halogen-free flame-retardant polyvinyl chloride cable material is prepared from, by weight, 80 parts to 100 parts of polyvinyl chloride resin, 10 parts to 14 parts of polyolefin resin, 7 parts to 9 parts of ethylene vinyl acetate copolymer, 2 parts to 3 parts of 2,2,4-Trimethyl-1,3-pentanediolmono(2-methylpropanoate), 8 parts to 10 parts of dioctyl sebacate, 3 parts to 5 parts of nanometer kaolin, 5 parts to 10 parts of antimonous oxide, 10 parts to 15 parts of aluminium hydroxide, 5 parts to 8 parts of butyl stearate, 7 parts to 9 parts of microcrystalline graphite powder, 8 parts to 12 parts of mica powder, 10 parts to 15 parts of wollastonite, 2 parts to 3 parts of antioxidant TPP, 1 part to 2 parts of insoluble sulfur, 40 parts to 50 parts of dimethyl terephthalate, 5 parts to 7 parts of triethoxyisobutylsilane, 6 parts to 8 parts of rare earth carboxylate stabilizers, 20 parts to 30 parts of nanometer calcium carbonate, 1 part to 2 parts of antioxidant 616, 12 parts to 14 parts of tetrabromophthalic anhydride, 7 parts to 9 parts of silicone emulsion and 7 parts to 8 parts of isophorone. By means of the synergistic effect of added antimonous oxide and chlorine elements in the added polyvinyl chloride resin, the flame-retardant property of polyvinyl chloride is enhanced; by means of compound plasticizers such as the added dioctyl sebacate, flexibility of cables is improved while the cold-resistant performance of products is improved.

Description

field of invention [0001] The invention relates to a cable material, in particular to a low-temperature-resistant halogen-free flame-retardant polyvinyl chloride cable material for automobiles and a preparation method thereof. Background technique [0002] Wire and cable are one of the important components of automotive electrical appliances. Taking advantage of the rapid development of the automotive industry, the automotive wire industry has developed rapidly. 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. Performance, and with the continuous change of vehicle functions, the requirements for automotive wires are also increasing. [0003] Polyvinyl chloride cable material is a general term for cable materials made of polyvinyl chloride. As a traditional cable material, it has excellent physical and mechanical properties, e...
