Abstract

The invention provides a high-performance low-VOC industrial anti-corrosion coating, which comprises the following components in parts by weight: 35-50 parts by weight of epoxy ester resin; 25-35 parts of pigment and filler; 8-16 parts of anti-rust pigment; Dispersant 0.1-0.5; defoamer 0.1-0.5; drier 0.2-1.0; leveling agent 0.1-0.5; floating liquid 15-25. The high-performance low-VOC industrial anti-corrosion coating has high solid content, low volatile organic compounds (VOC), less environmental pollution, good adhesion, excellent recoatability, good chemical resistance, water resistance and salt spray resistance; The invention designs special epoxy ester resins and additives, and optimizes weather-resistant pigments and anti-rust pigments to make the overall performance of the paint film more excellent, such as fullness, adhesion, salt spray resistance, and chemical resistance, especially salt resistance. Compared with the existing epoxy ester resin, the haze is greatly improved.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high-performance low-VOC industrial anti-corrosion coating and its preparation method 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. [0003] Existing anti-corrosion coatings are usually produced by epoxy ester, which can meet the coating and protection requirements of steel structures and auto parts surfaces; however, the paint film dries slowly, and it is easy to bite the bottom when it is matched with a topcoat, and it is diluted with organic solvents. agent, high...
