Abstract

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.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and relates to a protective coating and a preparation method thereof, in particular to a water-based quick-drying bottom surface integrated acrylic anticorrosive coating and a preparation method thereof. Background technique [0002] Quick-drying waterborne acrylic resin has the advantages of low VOC content, no peculiar smell, non-combustible and low toxicity. It has many varieties and excellent performance. It is widely used in paint production. Because water-based paints have gradually replaced organic solvent-based paints. However, water-based coatings also have high electrical conductivity, which is easy to cause metal corrosion, and flash rust is easy to occur during the drying process of the coating. Therefore, it is often necessary to add rust inhibitors to water-based paints for metals. In order to achieve a good anti-corrosion effect, the traditional method is to add anti-corrosion agents ...
