▎ 摘 要
NOVELTY - High damping graphene composite material comprises ethylene-vinyl acetate, maleic anhydride grafted ethylene-vinyl acetate, fumed silica, fillers, functionalized graphene, plasticizers and crosslinking agents. USE - The material is useful in car (claimed). ADVANTAGE - The material has low cost, simple operation, high production efficiency, larger damping peak and greatly enhances damping performance of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high damping graphene composite material comprising kneading ethylene-vinyl acetate resin, maleic anhydride grafted ethylene-vinyl acetate and plasticizer in internal mixer to obtain mixing rubber, then adding fumed silica, filler, functionalized graphene and crosslinking agent into mixing rubber, continue kneading, and removing out of the film.
