▎ 摘　　要

NOVELTY - Preparation of graphene-reinforced non-metal matrix composite material, involves (a) putting the graphene reinforcement into the ball milling tank, and then adding non-metallic materials and grinding balls, then adding the grinding aid to the ball mill tank for multiple times and performing ball milling until the raw materials are mixed into a uniform paste shape, and drying the ball milled slurry to obtain a composite powder, (b) processing the composite powder by two or more pressure sintering processes. USE - Preparation of graphene-reinforced non-metal matrix composite material by combining stepwise feeding and multiple pressure sintering. ADVANTAGE - The method has high dispersion efficiency, high dispersion stability, no damage to graphene structure, solves problem of easy agglomeration of graphene, effectively reduces sintering temperature, reduces energy consumption and improves mechanical property of material.
