NOVELTY - Method for preparing anticorrosive paint involves (i) dripping the aqueous polyurethane to the aqueous epoxy resin for cross-linking, and adding the silane coupling agent to fully cross-linking to obtain the composite coating, (ii) adding graphene oxide to water for ultrasonic dispersion, and adding the graphene oxide to the composite coating prepared in the step (i) to obtain the graphene oxide composite coating, (iii) dispersing montmorillonite in water, sequentially dripping ammonium salt and inorganic salt, dripping completely, heating, concentrating the colloidal solution, washing and drying to obtain the double-electric-layer material, and (iv) adding the double-layer material obtained in the step (iii) to water to be uniformly dispersed, dripping the mixture in the composite coating prepared in the step (i), and uniformly stirring. USE - Method for preparing anticorrosive paint (claimed). ADVANTAGE - The method enables preparation of anticorrosive paint with excellent corrosion resistance, by environmentally-friendly process.
