Thick-rust-filling-type over-rust treating fluid

Abstract

The invention discloses a thick-rust-filling-type over-rust treating fluid which is composed of the following raw materials: 3-5 parts of sodium alginate, 4-5 parts of sodium benzoate, 5-6 parts of benzoic acid, 5-10 parts of isobutyric acid, 3-5 parts of potassium polymetaphosphate, 5-8 parts of butylated hydroxytoluene, 6-8 parts of butylhydroxy methylbenzene, 7-10 parts of olein, 6-8 parts of dipotassium hydrogen phosphate, 6-8 parts of potassium hydroxide, 8-10 parts of hydrofluoric acid, 6-8 parts of sodium hexametaphosphate, 5-8 parts of disodium hydrogen phosphate, 10-12 parts of citric acid, 10-12 parts of zirconium oxychloride, 8-12 parts of zirconium dioxide, 8-10 parts of ammonium heptamolybdate, 9-12 parts of sodium hydrosulfite, 10-12 parts of boric acid, 6-8 parts of fatty alcohol polyethenoxy ether, 5-6 parts of alkylphenol polyoxyethylene, 40-50 parts of methyl pyrrolidone, 45-50 parts of polyvinyl butyral and 120-150 parts of deionized water. The thick-rust-filling-type over-rust treating fluid can implement quick conversion inside the rust layer even if the rust layer is thick, ensures every part of the rust layer to be completely converted, greatly enhances the conversion effect of the over-rust treating fluid, and enhances the firmness of the chelated film after the thick rust layer is treated.

Description

technical field [0001] The invention relates to the technical field of a treatment liquid, in particular to a thick rust filling type rust treatment liquid. Background technique [0002] Steel is prone to corrosion in the atmospheric environment. For the corrosion of corroded steel, it must be manually polished and derusted before it can be corroded and reused. However, manual grinding is difficult, costly, and the treatment effect is not ideal. Influenced by factors, if the rust removal process can be polished, the cost of painting can be significantly reduced, and the anti-corrosion process can be greatly simplified at the same time, thereby reducing labor intensity and reducing the harm of rust dust to the human body. In response to this, someone has developed a water-based rust treatment solution. [0003] However, the current common water-based rust treatment solution has limited conversion ability. Under normal usage conditions, it can only chelate and transform the r...

Problems solved by technology

[0003] However, the current common water-based rust treatment solution has limited conversion ability. Under normal usage conditions, it can only chelate and transform the rust layer on the surface. For thicker rust layers, the inner rust layer cannot be properly chelated. It cannot become dense, which affects the strength of the overall chelating film, making the treatment effect of the rust treatment solution very unsatisfactory
