Abstract

The invention discloses an environment-friendly water paint used in pump industry and a preparation method thereof and relates to the technical field of anticorrosive coatings. The environment-friendly water paint is prepared from, by weight, waterborne resin comprising 15-25% of polyester polyol, assistants comprising 0.12-0.35% of film forming additive, 0.9-2.1% of neutralizer, 0.18-1.5% of defoamer, 0.15-0.38% of dispersant, 30-37% of ionic water, 0.1-0.35% of wetting agent and 0.75-1.67% of drier, packing comprising 0.31-0.67% of carbon black, 5-12% of iron oxide black, 5-8.8% of 808 anti-rust material, 2.5-5.3% of compound zinc phosphate, 5.5-8.8% of compound ferrotitanium powder, 7-11.6% of barium sulfate and 1-3.3% of talcum powder, 4.3-7.8% of anti-sinking thixotropic agent. The paint has good environmental friendliness and meets the national standard requirements in the aspects of corrosion, rusting and impact resistance and the like.

Description

technical field [0001] The invention relates to the technical field of anticorrosion coatings. Background technique [0002] Nowadays, with the development of society, the rise of various companies has also promoted the development of the pump industry, which has also led to the rise of pump coatings. At present, there are as many as 5,000 large and small pump companies in the country. The pump is mainly used to transport liquids such as water, oil, acid and alkali, emulsion, suspension and liquid metal, and can also be used to transport liquid, gas mixture and liquid containing suspended solids. Therefore, it is particularly important to prevent corrosion and rust of the pump body. [0003] Pump outer coating belongs to the field of anti-corrosion coatings. At present, most of the coatings used in the pump industry are solvent-based. They will not only cause serious pollution to the air environment, but also cause certain harm to ourselves, affecting people's physical and...
