Aromatic hydrocarbon-free corrosion prevention scheme for metal structure

Abstract

The invention discloses an aromatic hydrocarbon-free corrosion prevention scheme for a metal structure. The aromatic hydrocarbon-free corrosion prevention scheme 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, and finally 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 aromatic-free anticorrosion solution for metal structures, in particular to a method for coating an environmentally friendly paint that is suitable for the surface of metal structures, 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 e...
