Novel steel-structure waterborne antirust paint based on rust and application method of novel steel-structure waterborne antirust paint

Abstract

The invention discloses novel steel-structure waterborne antirust paint based on rust. The novel steel-structure waterborne antirust paint comprises a solution A and a solution B, wherein the solution A is a steel-structure iron rust transfer solution and prepared from composite organic acid, a penetrating agent, nano titanium dioxide and water; the solution B is waterborne nano acrylic anticorrosive paint and is prepared from nano acrylic emulsion, nano titanium dioxide, graphene oxide and the like. The waterborne antirust paint based on rust can well convert iron rust on the surface of a rusty steel structure. By adopting the process for separately smearing the steel-structure iron rust transfer solution and the waterborne nano acrylic anticorrosive paint, the anticorrosive performance of the paint is good, and the storage time of the paint can be maximally improved at the same time.

Description

technical field [0001] The invention relates to a novel steel structure water-based antirust paint with rust and its application method. Background technique [0002] The annual economic loss caused by corrosion in our country is quite huge, exceeding the sum of the losses caused by natural disasters such as wind disasters, fires and earthquakes. As the amount of metal increases, its loss will continue to increase. The structure scrapped due to steel corrosion accounts for about 20% of the total steel output every year, so the anticorrosion of steel structure is a work that must be done. [0003] Coating anticorrosion is an important means of steel structure anticorrosion. Traditional solvent-based rust coatings have three disadvantages: first, large-scale derusting is required before construction, and this derusting work accounts for 40% of the entire derusting work; Coatings that use organic matter as solvents have high VOC, pollute the environment, waste resources, are ...

[0003] Coating anticorrosion is an important means of steel structure anticorrosion. Traditional solvent-based rust coatings have three disadvantages: first, large-scale derusting is required before construction, and this derusting work accounts for 40% of the entire derusting work; Coatings with organic matter as solvents have large VOC, pollute the environment, waste resources, are unsafe, and the rust conversion is not complete; third, most rusty coatings are acidic systems, which make the storage time of the coatings shorter
