The invention discloses water-based super-corrosion-resistance modified epoxy primer. The water-based super-corrosion-resistance modified epoxy primer comprises, by weight, 70-110 parts of epoxy resin, 80-120 parts of phenolic resin, 5-9 parts of modifier, 30-70 parts of acetone, 10-50 parts of butanol, 0.4-0.8 part of accelerant, 10-50 parts of zinc phosphate, 10-50 parts of aluminum triphosphate, 5-9 parts of rheological additives, 6-10 parts of flash rusting inhibitor and 1-5 parts of leveling agent. The water-based super-corrosion-resistance modified epoxy primer has the advantages that the primer is high in stability, the problem that water volatilization under low temperature and high relative humidity is slow is solved, the problem that some additives need to be added to improve thehigh surface tension of water, and thus adverse effects on water resistance and permeability are caused is solved at the same time, and increasing market demand is satisfied.
