▎ 摘　　要

NOVELTY - A composite foaming material comprises 40-60 parts mass ethylene-vinyl acetate copolymer, 10-20 parts mass graphene-modified isotactic polybutene, 10-15 parts mass polyolefin thermoplastic elastomer, 10-20 parts mass polyester elastomer, 0.4-0.8 part mass active agent, 0.7-1.5 parts mass crosslinking agent, 2.5-3.5 parts mass foaming agent and 0.1-0.3 part mass additive. Ethylene-vinyl acetate copolymer has vinyl acetate content of 26-40%. The composite foaming material is prepared by weighing raw materials and then mixing, kneading the mixture and then granulating and foaming. USE - Composite foaming material. ADVANTAGE - The composite foaming material has excellent foaming effect, compression resistance, resilience, softness and abrasion resistance, and can be prepared in simple and easy manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite foaming material, which involves melting quantitative isotactic polybutene-1, adding 0.05-0.2 %mass graphene, melting at 140-170 degrees C to obtain graphene-modified isotactic polybutene, mixing at 150-180 degrees C for 25-40 minutes, adding remaining raw materials and then kneading, adding crosslinking agent and foaming agent, mixing and then granulating and foaming.
