Abstract

The invention discloses a rare earth corrosion prevention method of a metal surface. The method comprises the following steps of: mixing siloxane, a solvent, silica particles, a rare earth compound, deionized water, a catalyst, a carbon fiber, polyimide and other components, performing curing treatment, filtering the cured mixture, spraying, or brush coating or impregnating the mixture on the surface of a base material, forming a coating on the surface of the base material after deposition, thus realizing the surface corrosion prevention treatment.

Description

technical field [0001] The invention relates to an anti-corrosion paint coating method, in particular to a coating method for an environmentally friendly paint which is suitable for the surface of a metal structure, has excellent gloss and mechanical and physical properties, and does not contain aromatic hydrocarbon solvents. Background technique [0002] In modern industry and daily life, metal corrosion can be seen everywhere, especially in the form of crevice corrosion, stress corrosion and corrosion fatigue in the storage containers of fuel oil and hazardous chemicals, which cause great safety hazards to people's lives. [0003] The metal protection methods currently used can be roughly divided into three categories: one is anodic oxidation treatment, that is, an anodic oxidation film with a thickness of tens of microns is formed on the metal surface, but due to the large energy consumption of the anodic oxidation process and the contamination of the electrolyte solution ...
