NOVELTY - Method for preparing an anticorrosive coating involves (i) preparing a graphene dispersion, (ii) adding a modified substance into a graphene dispersion liquid and stirring to obtain a modified graphene dispersion, where the modified substance adopts dodecylamine with a molecular weight of 185.35, (iii) adding the modified graphene dispersion to a zinc-containing coating component (A) and uniformly stirring to obtain a mixed solution and (iv) adding a zinc-containing coating component (B) to the mixed solution, uniformly stirring and curing. USE - The method is useful for preparing an anticorrosive coating. ADVANTAGE - The method avoids agglomeration of graphene, achieves anticorrosive effect of graphene in the coating, promotes crosslinking effect of graphene and zinc powder in the coating, improves anticorrosive effect of the coating, adopts simple preparation process and provides environmentally-friendly coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the anticorrosive coating prepared by the above method.
