Abstract

The invention discloses a high-strength and high-temperature resistance EVA composite material and a preparation method thereof. The composite material is prepared from, by weight, 35-45 parts of ethylene-vinyl acetate copolymer, 18-33 parts of brominated isobutene-p-methylstyrene copolymer, 15-25 parts of poly(benzimidazole-imide), 12-18 parts of nanometer palygorskite, 14-22 parts of polyphenylquinoxaline, 10-15 parts of epoxidized ethylene propylene diene rubber, 15-20 parts of colloidal graphite powder, 2-4 parts of zinc sorbate, 23-37 parts of artificial stone polishing waste powder, 14-19 parts of dipropylene glycol dibenzoate, 2-3 parts of stannous chloride, 1.5-2.5 parts of calcium stearate and 1-2 parts of barium stearate. The composite material prepared in the invention has excellent mechanical strength, high temperature resistance and weatherability, and still maintains high mechanical strength after long-term working in high temperature environment.

Description

technical field [0001] The invention relates to a modified EVA material and a preparation method thereof, in particular to a high-strength and high-temperature-resistant EVA composite material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is one of the polymer materials that has developed rapidly in recent years. It has good impact resistance, flexibility, low temperature resistance, environmental stress cracking resistance and other properties, and is widely used in wires. Cables, pipes, plates, building materials, toys, electrical accessories and other fields. With the rapid development of the polymer material industry, the performance requirements for EVA materials are getting higher and higher. The mechanical strength and high temperature resistance of EVA materials in the existing market are increasingly unable to meet the needs of the market, which limits its application range. Therefore, there is an urgent need...
