Abstract

The invention discloses a corrosion prevention process of a metal surface, which comprises the steps of: mixing the components such as siloxane, solvent, silica particles, rare earth compound, deionized water, catalyst, carbon fiber and polyimide, and then curing; filtering the cured mixture; and spraying, brushing or impregnating the filtered mixture on the surface of base material, wherein a coating is formed on the surface of the base material after deposition, thus realizing surface anti-corrosion treatment.

Description

Technical field [0001] The invention relates to an anti-corrosion process for metal surfaces, in particular to a coating method for environmentally friendly paints suitable for metal structure surfaces, having excellent gloss, mechanical and physical properties and not containing aromatic hydrocarbon solvents. Background technique [0002] In modern industry and daily life, metal corrosion can be seen everywhere, especially the damage in the form of crevice corrosion, stress corrosion and corrosion fatigue in storage containers of fuel and hazardous chemicals, causing great safety hazards to people's lives. [0003] The metal protection methods currently used can be roughly divided into three categories: One is to perform anodizing treatment, that is, to form a layer of tens of micrometers thick anodized film on the metal surface, but because the anodizing process consumes a lot of energy and the electrolyte solution is polluted Serious, difficult to handle, and its application is ...
