Abstract

The invention discloses a rare earth anticorrosive paint coating technology, which comprises the following steps of: mixing siloxane, a solvent, silicon dioxide particles, a rare-earth compound, de-ionized water, a catalyst, carbon fibers, polyimide and other components, and curing; filtering the cured mixture; spraying, brushing or dipping on the surface of a substrate; and obtaining a coating on the surface of the substrate after depositing, to realize surface anticorrosive treatment.

Description

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