Double layer abrasion resistance anti corrosive paint for aluminium alloy surface

Abstract

A dual-layer anti-flushing anticorrosion paint for the surface of Al-alloy has dual-layer structure. Its bottom layer is composed of the component A prepared from green epoxy enamel H04-1 and superfine Zn-Al (or Al) powder, and the component B (solidifying agent). Its surface layer is polyurethane varnish S01-3. Its advantages are excellent flushing and corrosion resistance, good toughness and high adhesion to Al-alloy.

Description

Technical field [0001] The invention relates to an anticorrosion coating for metal surfaces, which is especially suitable for use on aluminum alloy metal surfaces. Background technique [0002] At present, the research on the anti-erosion and anti-corrosion coatings on the surface of aluminum alloys at home and abroad has not been ideal. Usually, the anti-corrosion performance of the coatings is improved, and the anti-erosion properties of the coatings cannot be taken into account, especially when the coating is required to be around tens of microns. , On precision equipment and instruments working in coastal areas and on high-speed rotating parts, this problem is particularly prominent. Therefore, developing a kind of anti-scouring and anti-corrosion coating on the surface of aluminum alloy has always been an urgent topic to be solved at home and abroad. Contents of the invention [0003] The object of the present invention is to provide a double-layer erosion-resistant a...
