▎ 摘　　要

NOVELTY - Preparing graphene-coated mica material comprises (i) mixing mica with water, heating, adding zinc salt and urea and mixing well to obtain a mixed and (ii) adding an equal volume of a graphene aqueous solution to mixed solution, stirring, and drying to obtain material. USE - The preparing graphene-coated mica material is useful for added to a resin to preparing a graphene-coated mica heavy anticorrosive coating (claimed). ADVANTAGE - The method solves the problems of poor salt spray resistance and poor corrosion resistance of the heavy anticorrosive coating in the prior art. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-coated mica material.
