Abstract
The invention discloses an EVA flame-retardation composite material and a preparation method thereof. The EVA flame-retardation composite material is prepared from, by weight, 44-58 parts of ethylene-vinyl acetate copolymer, 25-35 parts of brominated polystyrene, 18-29 parts of polyetherimide, 11-17 parts of polypentabromobenzyl acrylate, 10-15 parts of rectorite, 6-12 parts of zinc phosphate, 5-9 parts of calcium molybdate, 12-18 parts of hexakis(4-formacylphenoxy)cyclotriphosphazene, 3-6 parts of sodium pyroantimonate, 4-7 parts of dibismuth trioxide, 16-22 parts of colemanite, 8-12 parts of isopropyl phenyl diphenyl phosphate, 3-5 parts of basic lead carbonate and 4-8 parts of low molecular weight polypropylene. EVA is blended and modified with brominated polystyrene, polyetherimide, polypentabromobenzyl acrylate and other polymer materials with good compatibility with the EVA, so the flame retardation performance of the EVA is improved, and the impact resistance, the chemical stability and the fatigue resistance of the EVA are improved.
Description
Technical field
The present invention relates to a kind of modified EVA material and preparation method thereof, be specifically related to a kind of EVA flame-proof composite material and preparation method thereof.
