▎ 摘　　要

NOVELTY - Preparation of graphene composite material, involves (1) mixing magnesium powder and aluminum oxide powder to obtain a mixed powder and (2) placing the mixed powder in a reactor, inducing a self-propagating combustion reaction by electric current in a carbon dioxide atmosphere and cooling. USE - Preparation of graphene composite material used in preparation of zinc-graphene anticorrosive paint. ADVANTAGE - The method for preparing graphene is environmentally-friendly, fast and efficient, and realize large-scale production. The preparation of graphene composite material ensures simple operation, short cycle and low cost.
