Problems solved by technology

[0002] At present, 90% of the steel structure factories in the market still use oily alkyd antirust paint for operation. Oily alkyd antirust paint contains a large amount of organic solvents, which causes extremely serious pollution to the environment; and oily alkyd antirust paint smells Large, slow drying, poor salt spray resistance and artificial aging resistance, so water-based antirust paint is one of the research directions of the coating industry in various countries
The existing water-based anti-rust coatings still have some deficiencies in terms of anti-rust performance, salt water resistance, and salt spray resistance. In this regard, how to improve the deficiencies of the existing technology is a problem that we need to solve

Abstract

The invention discloses a water-based antirust paint and a preparation method thereof. In parts by weight, the raw materials of the water-based antirust coating include: 33-56 parts of water-based resin, 12-24 parts of iron oxide red powder, 3-11 parts of zinc phosphate, 2.2-3.8 parts of modified aluminum tripolyphosphate, (1250 mesh ) mica powder 2.4-6.7 parts, barium sulfate (800 mesh) 0.8-3.2 parts, defoamer 0.8-2.1 parts, film-forming agent 1.3-3.6 parts, stabilizer 0.1-0.4 parts, dispersant 0.11-0.26 parts, increase 0.05-0.16 parts of thickener, 15-28 parts of deionized water, 1.5-2.7 parts of compound anti-corrosion additive. The beneficial effects of the present invention are: the performance of this product is equivalent to solvent-based antirust paint, the product has a fast drying speed, improves the painting production efficiency, improves the work efficiency; improves the flexibility and adhesion of the product, and reduces the VOC emission, energy saving and environmental protection.
