Abstract

The invention discloses a thermoplastic low-smoke halogen-free high-flame-retardant material for an automobile wire and a preparation method of the material. The thermoplastic low-smoke halogen-free high-flame-retardant material comprises the following components in parts by weight: 80-90 parts of a polyolefin substrate, 10-20 parts of a compatilizer, 0.5-1.5 parts of an antioxidant, 150-170 parts of a flame retardant, 1-3 parts of a lubricant, 1-3 parts of a silane coupling agent and 0-6 parts of halogen-free master batch, wherein the total part by weight of the polyolefin substrate and the compatilizer is 100 parts. According to the material disclosed by the invention, good oil-resistant and wear-resistant effects can be achieved without irradiation and thus the cost is decreased and meanwhile, the flame-retardant grade can reach a very high level and the material is particularly excellent in mineral oil resistance, gasoline resistance and thermal-conducting oil resistance. The thermoplastic low-smoke halogen-free high-flame-retardant material is wear resistant, high temperature resistant, oil resistant, high flame retardant and is harmless and can be well applied in the automobile wire; meanwhile, the preparation method disclosed by the invention is simple in steps and is easy to operate.

Description

technical field [0001] The invention relates to the field of cable material and its preparation, in particular to a thermoplastic low-smoke, halogen-free, highly flame-retardant material for automobile wires and a preparation method thereof. Background technique [0002] The environment where the automobile wire is located is generally oily, and with the operation of the automobile, there will be friction with the surrounding objects. Therefore, in addition to flame retardancy and heat resistance, automotive wires are also particularly required to have wear resistance and oil resistance. [0003] At present, on the market, most automobile wires still use cable materials and radiation cross-linking materials based on polyvinyl chloride. Although polyvinyl chloride-based cable materials have the advantages of low price, good flame retardancy and good processing performance; but they contain halogens, which do not comply with the European Union's "Directive on Prohibiting the ...
