Chemically-crosslinked dual-oil-resistant low-temperature-tolerant low-smoke halogen-free flame-retardant jacket material and preparation method thereof

摘要: The invention relates to a chemically-crosslinked dual-oil-resistant low-temperature-tolerant low-smoke halogen-free flame-retardant jacket material and preparation method thereof. is made from, by mass, 60-90 parts of ethylene-vinyl acetate copolymer A, 15-45 B, 10-15 EPDM-G-PU polymer, polypropylene powder, 2-5 paraffin oil, 0.5-4 vinyl-tris(beta-methoxyethoxy)silane, 1-1.5 of4,4-bis(2,2-dimethylbenzyl)diphenylamine, 1-8 2-mercaptobenzimidazole, 100-150 filling material, 1-6 zinc borate, antimony oxide, ofmontmorillonite, 2-6 dicumyl peroxide, 1-4 triallyl isocyanurate. A EVA40L-0.3 having density 0.96 g/cm , melt flow rate 3 g/10min VA content 40%. herein has low hardness, still flexible at the temperature -40 DEG C, good flame retardancy excellent mineral resistance fuel performance.
