Coating process of copper alloy foil explosion-proof material

Abstract

The invention discloses a coating process of an anticorrosive coating and relates to a coating process of a copper alloy foil explosion-proof material. The process comprises the following steps of: mixing siloxane, solvents, silicon dioxide particles, rare earth compounds, deionized water, catalysts, carbon fibers, polyimide and the like; performing curing treatment; filtering the cured mixture; spraying or brushing the mixture on the surface of an explosion-proof substrate or dipping the mixture into the surface of an explosion-proof substrate; and depositing and forming a coating layer on the surface of the explosion-proof substrate so as to realize surface anticorrosive treatment.

Description

technical field [0001] The invention relates to an anti-corrosion paint coating process, in particular to a coating process for metal foil explosion-proof materials, especially copper alloy foil explosion-proof materials. The method uses an environmentally friendly paint that does not contain aromatic hydrocarbon solvents. 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 the storage containers of hazardous fuel chemicals, especially the damage in the form of corrosion of metal explosion-proof materials, which have caused great harm to people's lives. Great security risk. The manufacturing process of the metal explosion-proof material generally includes: ingot casting, rolling into foil, slitting with a slitting machine, and stretching to form a mesh material. [0003] The metal protection methods currently used can be roughly divided into three...

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.
