NOVELTY - Aqueous anti-corrosion primer comprises 40-60 pts. wt. aqueous epoxy resin, 10-25 pts. wt. deionized water, 10-20 pts. wt. pigments and fillers, 0.2-2 pts. wt. rheological agent, 0.2-1 pt. wt. anti-settling agent, 0.2-1 pt. wt. defoamer, 0-2 pts. wt. dispersant, 0.2-0.5 pt. wt. wetting agent, 1-5 pts. wt. graphene, 0.5-1.5 pts. wt. polyamide wax slurry, 0.3-0.8 pt. wt. anti-flash rust agent, 2-8 pts. wt. crosslinking agent, and 0.2-2 pts. wt. silane coupling agent. USE - The aqueous anti-corrosion primer is useful for electrostatic coating. ADVANTAGE - The primer does not need to add any organic solvent during production and use, and is safe, environmentally-friendly, and easy for atomization, and has low viscosity, excellent leveling effect, ultra-low volatile organic compound, excellent mechanical properties, wear resistance, impact resistance, high hardness, excellent water resistance and anti-corrosion performance, and can form a uniform film on workpieces with complex structures and difficult to adhere. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the primer, involving mixing deionized water and anti-settling agent, dispersing and activating at high speed, adding defoamer, dispersant, graphene and pigments and fillers, dispersing at high speed or sand mill to a suitable fineness, adding the wetting agent, silane coupling agent, polyamide wax paste, anti-flash rust agent, rheological agent, crosslinking agent, mixing, adding the aqueous epoxy resin, and mixing to obtain the product.
