▎ 摘　　要

NOVELTY - Resin material modified by graphene oxide-based composite material, is prepared by mixing graphene oxide-based composite material in situ in the process of synthesizing polypropylene resin by suspension polymerization to obtain modified resin material, and the sphericity after grinding is increased 43.76% to 88.62-91.78%. The graphene oxide-based composite material comprises one or more of graphene oxide, and magnesium-aluminum hydrotalcite-graphene composite material. USE - As resin material modified by graphene oxide-based composite material. ADVANTAGE - The resin material has significantly improved mechanical properties, and reduces the damage and loss of the resin and the secondary pollution caused by the loss in practical applications.
