This invention relates to the field of coatings, specifically to a water-based epoxy glass flake heavy-duty anti-corrosion coating and its preparation method, comprising 11.5-12.5 parts water, 1-1.2 parts dispersant, 0.5-0.6 parts wetting and defoaming agent, 0.2-0.3 parts defoamer, 1.1-1.2 parts anti-settling agent, 49-51 parts water-based epoxy resin dispersion, 3-3.4 parts rust-inhibiting pigment, 30-36.5 parts graded glass flakes; 9.8-10.2 parts water-based amine copolymer, 1.3-1.4 parts flash rust inhibitor, and 1.5-2.5 parts water. This anti-corrosion coating contains no solvents and has low VOCs. The anti-corrosion performance of the coating can be improved by adding two rust-inhibiting pigments and fillers: aluminum tripolyphosphate, zinc strontium phosphate, and glass flakes. Neutral salt spray and seawater immersion tests showed that the coating film did not bubble, rust, or peel after 12,000 hours of immersion.
