Abstract

The invention discloses an aqueous rust resisting paint and a preparation method thereof in the technical field of coatings. The aqueous rust resisting paint comprises the following components, by weight, 10-40% of deionized water, 0.1-0.3% of a bactericide, 1-3% of a film forming assistant, 0.2-0.4% of a multifunctional assistant, 2-5% of iron oxide, 50-70% of a rust resisting emulsion, 0.1-0.3% of a polyurethane thickening leveling agent, 2-3% of a thickening agent, 0.5-1.0% of sodium nitrite, 0.15-0.4% of a defoamer, 0.1-0.2% of a dispersant, 0.05-0.1% of a wetting agent and 0-8% of titanium dioxide. The aqueous rust resisting paint provided in the invention is diluted with water, so the construction danger is substantially lower than the construction danger of rust resisting paints diluted with organic solvents such as banana oil and the like; and the aqueous rust resisting paint can be directly applied to various metal surfaces, and can be compiled with any coating finishes regardless of being rusted or being painted.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and specifically relates to a water-based antirust paint and a preparation method thereof. Background technique [0002] Rust is a global problem, and she can be found even in outer space. The thinner used in traditional anti-rust paint is volatile organic solvents, such as gasoline, toluene, xylene, banana water, etc., to help form the coating film. Such organic solvents not only waste resources and pollute the environment, but also contribute to production and construction. The place brings danger, such as fire, explosion, etc. In addition, this kind of paint must remove the rust on the metal surface before application, which is time-consuming and not effective. Summary of the invention [0003] In view of this, the purpose of the present invention is to provide a water-based anti-corrosion paint that can be directly applied to any metal surface and a preparation method thereof, so as to solve man...
