Abstract

The invention relates to the field of coatings and in particular discloses a highly anticorrosive epoxy coating. The highly anticorrosive epoxy coating is composed of the following raw materials: aqueous epoxy resin, a UV (Ultraviolet) absorbent, a light stabilizer, a pH adjuster, wetting dispersant 0.1-0.5 part, deionized water, a coalescing agent and an aqueous fatty amine curing agent. The highly anticorrosive paint has good construction performance, strong adhesion to metal, extremely low irritation and no emission of VOC (Volatile Organic Compounds), and is environment-friendly.

Description

technical field [0001] The invention relates to the field of heavy-duty anti-corrosion coatings, in particular to a strong anti-corrosion epoxy coating and a preparation method thereof. Background technique [0002] With the development of modern society, the improvement of human living standards, the gradual awakening of energy conservation and environmental protection awareness, and the rapid development of polymer science, the requirements for environmental protection are becoming more and more stringent. [0003] With the formulation of the local standard of Guangdong Province "Volatile Organic Compound Emission Standards for Container Manufacturing Industry", and the national taxation department levying consumption tax on paint products with high VOC content; the comprehensive water-based coating of containers is becoming more and more urgent. [0004] It can be foreseen that for a long time in the future, the development of environmentally friendly water-based coatings...
