NOVELTY - Aqueous EAU anti-corrosive paint comprises 55-65 wt.% aqueous EAU acrylic emulsion, 0.5-1 wt.% dispersant, 0.2-0.5 wt.% antifoaming agent, 0.4-1 wt.% leveling agent, 9-14 wt.% deionized water, 20-30 wt.% pigment and filler, 1-5 wt.% co-solvent, 0.5-1 wt.% anti-flash rust agent, 0.2-3 wt.% graphene dispersion and 0.2-0.6 wt.% thickening agent as component A and aqueous polyurea resin and/or polyisocyanate curing agent as component B. The weight ratio between component A and component B is 10:3-4. USE - Used as aqueous EAU anti-corrosive paint. ADVANTAGE - The anticorrosive paint has excellent weather resistance; and can protects the substrate in harsh environments. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing aqueous EAU anti-corrosive paint comprising (i) adding diphenylamine sulfonate and graphene into de-ionized water and stirring at the rotating speed of 450-550 revolutions/minute for 15-25 minutes and ultrasonically vibrating for 40-60 minutes to obtain graphene dispersion liquid, (ii) adding dispersant and antifoaming agent into e de-ionized water, stirring at the rotating speed of 250-350 revolutions/minute for 4-6 minutes, raising the rotating speed to 450-550 revolutions/minute, stirring while adding pigment and filler, stirring at the rotating speed of 750-850 revolutions/minute for 27-35 minutes to obtain dispersed slurry, the fineness of the dispersed slurry is less than 40 mu m, (iii) adding co-solvent, aqueous EAU acrylic emulsion, anti-flash rust agent, graphene dispersion, leveling agent and thickening agent into the dispersion slurry in step (ii) and then stirring at a rotating speed of 450-550 revolutions/minute for 4-8 minutes and carrying out filtration to obtain filtrate i.e. component A and then mixing component A and component B in a certain weight ratio to obtain aqueous EAU anticorrosive paint.
