Abstract

The invention discloses an anticorrosion scheme for a metal surface, which comprises the following steps: mixing siloxane, solvent, silicon dioxide particle, rare-earth compound, deionized water, catalyst, carbon fiber, polyimide and other components, aging, filtering the aged mixture, and applying the mixture on a substrate surface by spraying, brushing or impregnation to form a coating on the substrate surface after deposition, thereby implementing surface anticorrosion 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 ...
