Problems solved by technology

[0003] There are few types of water-based epoxy ester resins available in the market, most of which are emulsion-type water-based epoxy ester resins. The performance of water-based industrial anti-corrosion paints prepared with them is poor, and the hardness, salt spray resistance and chemical medium resistance cannot meet the index requirements.
Solvent-based epoxy ester anti-corrosion coatings can meet the coating and protection requirements of steel structures and auto parts surfaces, but the paint film dries slowly, and it is easy to bite the bottom when it is matched with the top coat. Moreover, it uses organic solvents as diluents and has high VOC content. ,polluted environment
However, the physical and chemical properties of water-based industrial anti-corrosion coatings prepared by acrylic emulsion and water-based epoxy ester emulsion can only meet the general decoration protection requirements, and are not suitable for industrial fields with high requirements for salt spray resistance and chemical medium resistance.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high-performance water-based industrial anticorrosion coating and a preparation method thereof. Background technique [0002] Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. Anti-corrosion coatings mainly include solvent-based epoxy ester anti-corrosion coatings, water-based industrial anti-corrosion coatings, etc. [0003] There are few types of water-based epoxy ester resins available in the market, most of which are emulsion-type water-based epoxy ester resins.
