NOVELTY - A graphene material comprises 40-70 pts. wt. ethylene-vinyl acetate copolymer, 30-60 pts. wt. ethylene-propylene-diene rubber, 20-40 pts. wt. graphene oxide, 8-15 pts. wt. glass fibers, 3-10 pts. wt. tetrapod zinc oxide crystal whisker, 3-5 pts. wt. expanded vermiculite, 1-2 pts. wt. coupling agent, 1-2 pts. wt. crosslinking agent and 0.5-1 pt. wt. antioxidant. USE - Graphene material is used for vehicle. ADVANTAGE - The graphene material has excellent sound insulation effect by containing reduced amount of tetrapod zinc oxide crystal whisker as filler. The graphene oxide, copolymer and rubber contained in the graphene material have excellent solubility. The friction loss caused by interfacial slip between the copolymer and the rubber effectively causes energy dissipation, such that sound insulation effect of the graphene material is improved.
