Anticorrosive paint, coating and preparation method thereof

The invention relates to the technical field of metal corrosion prevention, in particular to an anticorrosive paint, a coating and a preparation method thereof. The anticorrosive paint is prepared from the following raw materials: a film forming substance, a curing agent, a diluent, graphene oxide, boron nitride, nano magnesium oxide and/or nano cerium dioxide. The anticorrosive paint can be used for preparing an aluminum alloy surface functional anticorrosive coating, and can be applied to household appliances such as air conditioners, refrigerators, freezers, washing machines and the like, and other industries such as high-speed rails, motor cars, airplanes and the like. Compared with the prior art, the anticorrosive coating disclosed by the invention has the beneficial effects of good long-acting anticorrosive effect and low production cost. The long-acting corrosion prevention coating can meet the use requirement of an aluminum alloy base material for long-acting corrosion prevention. 本发明涉及金属防腐技术领域，特别是涉及一
