Method for coating austenite-stainless-steel-band explosion-proof material

Abstract

The invention discloses an anticorrosive paint coating method. The method comprises the steps of mixing ingredients, such as siloxane, a solvent, silicon dioxide particles, a rare-earth compound, deionized water, a catalyst, carbon fibers and polyimide, then, carrying out aging treatment, filtrating an aged mixture, then, spraying, brushing or dipping the mixture on the surface of an explosion-proof base material, and forming a coating layer on the surface of the explosion-proof base material after the mixture is deposited, thereby realizing anticorrosive surface treatment.

Description

technical field [0001] The invention relates to an anti-corrosion paint coating method, in particular to a method for coating metal strip explosion-proof materials, especially an austenitic stainless steel strip explosion-proof material. The method uses an environmentally friendly paint without aromatic hydrocarbon solvent. Background technique [0002] In modern industry and daily life, metal corrosion can be seen everywhere, especially the crevice corrosion, stress corrosion and corrosion fatigue in storage containers of hazardous fuel chemicals, especially the corrosion of stainless steel belt explosion-proof materials, etc. cause great safety hazards. The manufacturing process of the stainless steel belt explosion-proof material generally includes: rolling stainless steel into a belt, cutting with a slitting machine, and stretching to form a mesh material. [0003] The metal protection methods currently used can be roughly divided into three categories: one is anodic ox...

Problems solved by technology

Rare earth conversion coating technology is mainly immersion treatment, which is simple to operate and easy to maintain; but its disadvantages are that the long-term immersion process takes too long to form a thin film layer and poor adhesion to explosion-proof substrates

After long-term exploration and research, it is found that adding a strong oxidizing agent, such as H 2 o 2 , KMnO 4 , (NH 4 ) 2 S 2 o 8 Such strong oxides greatly increase the film forming rate and greatly shorten the treatment time. At the same time, the temperature of the treatment solution is not high, so it can be applied at room temperature, but the stability of the treatment process is poor due to the existence of strong oxidants.
