Recoating type universal epoxy anticorrosive paint for achieving four-season constructions with single curing agent

The invention discloses a recoating type universal epoxy anticorrosive paint for achieving four-season constructions with a single curing agent. A low molecular weight bisphenol A epoxy resin is usedas a resin base, a solvent system of an reactive diluent with branched chains, such as a glycidyl ether type reactive diluent, is introduced into the formulation to form an effective steric effect andprolong the usable life of a product after mixing, and after a coating layer is formed, the curing speed is not influenced, so the construction at the environment temperature of between 10 DEG C below zero and 40 DEG C is achieved, and the problem of the four-season constructions is solved by using one curing agent. A nano anticorrosive pigment, a phenolic amine curing agent, an adhesion promoter, adjusting PVC and a proper amount of dimming powder are selected, and the coating layer is ensured to contain a proper amount of polar groups so that the product has good cathodic disbonding resistance and can be matched with various types of finishing paints. The recoating type universal epoxy anticorrosive paint can be used as an anticorrosive primer for a plurality of positions from a ship bottom to a hull, and has very significant functions of improving the efficiency and the benefit of ship painting.
