Problems solved by technology

Moreover, after rust occurs, there are generally two methods of mechanical derusting and chemical derusting, the process is complicated, and it will cause certain damage to the environment.
Especially for the existing steel-based buildings, only manual rust removal can be used, and the rust removal effect is difficult to meet the requirements, resulting in the failure of the subsequent coating effect to meet expectations
[0003] Rust coating is currently a way to solve the above problems. In recent years, different types of rust conversion coatings have appeared. For parts with serious corrosion, rust conversion coatings cannot penetrate, and the film-forming sealing performance after conversion is not good enough.

Abstract

The invention discloses a preparation method of a rust conversion agent. The preparation method comprises the following steps: 1, adding 6-30 parts by weight of water and 6-30 parts by weight of ethanol into a mixing barrel, and uniformly mixing and stirring; 2, adding 1-5 parts by weight of tannic acid, and stirring while adding until solids are completely dissolved; 3, sequentially adding 0.3-1.5 parts by weight of isopropanol and 1-5 parts by weight of phytic acid, and continuously stirring until the solution is clear to prepare a solution A; and 4, adding 0.2-1 part by weight of flavonoid substances, 0.2-1 part by weight of phytic acid and 0.2-1 part by weight of biological organic acid into 6-30 parts by weight of Chinese lacquer emulsion, and fully stirring and mixing the materials to prepare a solution B. The rust conversion agent is high in invasion performance, permeates into the deep part of a rust layer and is chelated with iron rust, a paint film and metal crystal grains, so that a uniform and compact passivation reaction film and a cross-linked coating film which are extremely high in chelating force are formed; and further oxidation corrosion is prevented.

Description

technical field [0001] The invention relates to the technical field of antirust coatings, in particular to a preparation method of a rust transfer agent. Background technique [0002] Steel will corrode under natural conditions, which not only affects its appearance, but also causes major safety accidents. In the prior art, anticorrosion coatings are usually used to treat steel base materials, and strict surface derusting treatment is carried out before coating the steel base materials. Moreover, after rust occurs, two methods of mechanical derusting and chemical derusting are generally used at present, the process is complicated, and it will cause certain damage to the environment. Especially for existing steel-based buildings, only manual derusting can be used, and the derusting effect is difficult to meet the requirements, resulting in the failure of the subsequent coating effect to meet expectations. [0003] Rust coating is currently a way to solve the above problems....
