The invention provides a water-based steel structure anti-corrosion water dispersion coating, a preparation method and an application thereof, wherein the water-based steel structure anti-corrosion water dispersion coating comprises the following components: deionized water, an auxiliary agent, an antirust pigment, a pigment filler, a modified nano water dispersible polymer emulsion, color paste, a defoaming agent and the like. The water-based steel structure anticorrosion water dispersion coating is nontoxic, tasteless, odorless, nonirritating, good in stability, less influenced by construction environment, suitable for construction of different special-shaped steel structures, and suitable for coating equipment in different forms; the coating can be coated on steel structure base surfaces with low surface treatment grade St1, wet base surfaces, slight rust layers and firm old coating, has strong coating adhesion, good rust resistance and excellent salt mist resistance and weather resistance, reaches or exceeds the main technical performance indexes of common solvent-based anticorrosive coatings, and has long service life. |
