Abstract

The invention provides a low-smoke, halogen-free and flame-retardant cable material and a preparation method thereof. The material is prepared from the following raw material by weight parts: 34-38 parts of ethane-vinyl acetate copolymer, 24-27 parts of linear low-density polyethylene, 12-14 parts of ABS, 2-3 parts of zinc oxide, 50-54 parts of attapulgite powder, 12-14 parts of aluminium hydroxide, 1-2 parts of an antioxidant OD, 1-2 parts of an antioxidant ODA, 1-2 parts of an accelerator TETD, 5-7 parts of glycerol triglycerol ester, 3-4 parts of vinyl triethoxysilane, 1-2 parts of phenyl triethoxysilane, 3-4 parts of 2-methyl methacrylate, 1-2 parts of ethene diamine, 13-16 parts of carbon black N 220, 10-12 parts of carbon black N 339, 3-5 parts of polyethylene wax, 1-2 parts of ethylene bisstearamide, 1-2 parts of dimethyl tin dichloride, 4-6 parts of polyisobutylene and 6-8 parts of modified diatomite. According to the invention, the raw materials are reasonable in formula; the produced cable material is high in mechanical property, high temperature resistant, high in flame-retardant performance, and low-smoke and nontoxic during combustion, with a flame retardation grade being V2-V0.

Description

technical field [0001] The invention belongs to the technical field of cable materials, and more particularly relates to a preparation method of a low-smoke halogen-free flame-retardant cable material. Background technique [0002] Wire and cable materials are mainly made of resin materials, fillers, plasticizers, antioxidants, flame retardants, antioxidants, etc. The formula raw materials are mainly concentrated in some common ingredients, resulting in low technical indicators of cable materials or The problems of high cost, such as low volume resistivity, high temperature resistance, low temperature resistance, flame retardancy, insulation, etc., cannot meet the requirements of cable manufacturers for higher electrical performance of insulation-grade sheathing materials. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of low-smoke halogen-free flame retardant cable material and preparation method thereof, the present invention ...
