Rust-melting, antirust colour-changing priming paint

Abstract

The present invention discloses a rust-digesting rust-inhibiting temperature sensitive paint primer. It comprises A solution and B solution mixture, can be applied or sprayed on the surface of steel or iron, and can be reacted with rust on the steel or iron surface to produce a paint colour film, said film can be tightly stuck on the surface of the metal so as to produce the action of protecting steel or iron.

Description

technical field [0001] The present invention relates to a coating composition characterized by the effect produced, in particular a primer with antirust effect. Background technique [0002] Rust is a product of oxidation and corrosion on the surface of steel, which causes steel to be oxidized and corroded from the surface to the inside, resulting in qualitative changes, which does great damage to steel and causes great economic losses. Therefore, in order to prevent rust, people generally adopt iron red primer or silver gray primer to be coated on the surface of steel at present, so that the oxygen in the air is isolated from the steel surface, and the effect of protecting the steel surface from corrosion is played. To apply the primer, the rust layer on the steel surface must be removed before the primer can be applied. The work of derusting is very hard and heavy. It needs to be brushed with emery cloth or sandpaper or steel wire brush. During the process of grinding and...

AI Technical Summary

Problems solved by technology

The work of derusting is very hard and heavy. It needs to be brushed with emery cloth or sandpaper or steel wire brush. During the process of grinding and brushing, iron dust will fly and pollute the environment. The operator must wear a mask, otherwise it will affect health

Moreover, the work efficiency is low and the cost is increased

Of course, sand blasting, acid derusting or mechanical derusting methods can also be used, but the cost of these methods is relatively high and the operation is more difficult.

Therefore, it is difficult to widely apply
