▎ 摘　　要

NOVELTY - Modified graphene/styrene-butadiene rubber composite comprises vulcanization accelerator including promoter TMTD or promoter CBS; antioxidant including antioxidant RD, antioxidant NB, antioxidant 445, antioxidant 2246 or antioxidant ODA and coupling agent including aluminate coupling agent, rare earth coupling agent, silane coupling agent or titanate coupling agent. USE - Used as modified graphene/styrene-butadiene rubber composite. ADVANTAGE - The rubber composite: has mechanical performance and physical performance, cross linked structure and improves the mechanical strength of styrene-butadiene rubber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the modified graphene/styrene-butadiene rubber composite, comprising (i) adding 100 pts. wt. styrene-butadiene rubber matrix into a double-roller for plasticating to obtain plastic rubber, (ii) dissolving 0.05-1.4 pts. wt. the coupling agent in a 0.1- 0.5 pts. wt. ethanol solution has volume concentration of 10-50%, adding graphene oxide, heating at 80-100 degrees C so that the ethanol is completely volatilizing to obtain modified graphene oxide, where the amount of the coupling agent is 0.5-3.5 wt.% of the amount of the graphene oxide, (iii) taking the plastic compound obtained in the step (i) and the modified graphene oxide obtained in the step (ii), adding 1-2 pts. wt. vulcanization accelerator and 0.5-1.5 pts. wt. antioxidant to the twin-roll mill and kneading and vulcanizing to obtain modified oxidized graphite/ styrene-butadiene rubber composite.
