▎ 摘　　要

NOVELTY - Method for preparing graphene/carbon black composite pellets involve configuring graphene into a certain concentration of graphene aqueous solution, ultrasonically treating the graphene aqueous solution, directly adding to carbon black granulated water, adding binder, vigorously stirring and mixing the mixture, and passing through a carbon black granulator to obtain the product. USE - The method is useful for preparing graphene/carbon black composite pellets for preparing polymer rubber composite material (all claimed). ADVANTAGE - The method solves the application problem that graphene is difficult to disperse uniformly in polymer material, has mild reaction conditions, uses rich raw material source, and is simple, safe and environmentally-friendly.
