Anticorrosive coating and preparation method thereof

The invention provides an anticorrosive coating and a preparation method. The anticorrosive coating comprises the following components in parts by weight: 35-55 parts of metal powder, 45-55 parts of resin, 1-5 parts of functional filler, 10-50 parts of an auxiliary material mixture and 20-40 parts of a curing agent, wherein the functional filler added in the anticorrosive coating is one or more of conductive carbon black, conductive carbon fiber or graphene, so that the anticorrosive coating obtained by the method provided by the invention still has very good anticorrosive performance under the condition that the content of the metal powder is relatively low, and the anticorrosive coating also has good adhesive force; moreover, the anticorrosive coating provided by the invention is stable in performance, has no special requirement for construction conditions, and can be applied widely.
