Water-based quick-drying primer-topcoat acrylic anti-corrosion paint and preparation method thereof

The invention discloses water-based quick-drying primer-topcoat acrylic anti-corrosion paint. The paint comprises water-based acrylic resin, rutile type titanium dioxide, water-based aluminium tripolyphosphate, an anti-rust pigment, LT bentonite, phthalocyanine green, iron oxide yellow, deionized water, carbon black and an aid; the deionized water, a wetting agent, a dispersing agent, a defoaming agent and a flash rusting resisting agent are added to a dispersing machine in the preset mass ratio, the rutile type titanium dioxide, the water-based aluminium tripolyphosphate, water-based zinc phosphate, the LT bentonite, the phthalocyanine green and the iron oxide yellow are added sequentially, the water-based acrylic resin is added and sent into a stirring kettle to be heated and dispersed at the high speed, and when the temperature in the kettle is 40 DEG C, a coalescing agent and a thickening agent are added for full mixing. The water-based quick-drying primer-topcoat acrylic anti-corrosion paint is safe and environment-friendly, physical, chemical and construction properties of the water-based quick-drying primer-topcoat acrylic anti-corrosion paint are obviously better than those of existing paint, surface drying is realized within 10 min without heating of a film, curing is realized within 2 h, and the paint is best applicable to high-yield production chain procedure process coating.
