Problems solved by technology

When the existing common antirust paint is painted on the surface of metal products, it is required to completely remove rust on the surface of metal products. Good rust removal treatment, therefore, rust-resistant anti-rust paint has gradually developed, which can be directly painted on the surface of slightly rusted metal products. At present, phosphoric acid-potassium ferrocyanide-polymer is commonly used at home and abroad Vinyl butyral is the main component of the rust coating. Although this rust coating has a certain conversion effect on the rust layer, but due to the poor physical properties of the film-forming material, the anti-rust effect of the coating is not strong. It is generally suitable to be used as a pre-painting treatment agent, so how to prepare a better rust paint is a technical problem to be solved

Abstract

The invention discloses a surface anti-rust paint for a metal product and relates to the technical field of metal products. The surface anti-rust paint is prepared from the following components: rosinmodified alkyd resin, an acrylate emulsion, polyether-modified silicone oil, petroleum sulfonate, dimethylbenzene, zinc phosphate, barium naphthenate, polyphosphate, methyl isobutyl ketone, triethanolamine, chitosan, nanometer silicon dioxide and inositol hexaphosphate. The surface anti-rust paint for the metal product, disclosed by the invention, is suitable for the metal product placed outdoorsand can effectively prevent the metal product from chemical or electrochemical corrosion in the atmosphere and the like.

Description

technical field [0001] The invention belongs to the technical field of metal products, and in particular relates to a surface antirust paint for metal products. Background technique [0002] During the use of metal products, the surface is extremely vulnerable to damage such as wear and corrosion. In order to prolong the service life of metal products, it is often necessary to paint the metal products. When the existing common antirust paint is painted on the surface of metal products, it is required to completely derust the surface of metal products. Good rust removal treatment, therefore, the rust-resistant anti-rust paint has been gradually developed, which can be directly painted on the surface of slightly rusted metal products. At present, phosphoric acid-potassium ferrocyanide-polymer Vinyl butyral is the main component of the rust coating. Although this rust coating has a certain conversion effect on the rust layer, the anti-rust effect of the coating is not strong d...
