▎ 摘　　要

NOVELTY - Composite elastomer composition comprises 85-95 pts. wt. styrene-butadiene rubber (SBR), 0.5-2 pts. wt. graphene and 6-11 pts. wt. additives. USE - The composition is useful for railways (claimed). ADVANTAGE - The composite elastomer composition has excellent durability, improves wear resistance and mechanical strength, so that it can be used for long time in railways where lot of vibration occurs; and can be melt-kneaded with various injection-molding machines. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing composite elastomer, comprising (a) mixing 85-95 pts. wt. SBR, 0.5-2 pts. wt. graphene, 0.5-2 pts. wt. powder, 0.5-2 pts. wt. carbon black, and 5-9 pts. wt. process oil at room temperature to prepare a dough; (b) injecting the dough into a mold by injecting it; and (c) releasing the injected dough from the mold and solidifying it at room temperature.
