Problems solved by technology

[0002] With the development of the economy, people pay more and more attention to environmental protection, especially for large-scale steel structure factories, the profit of steel structures is very low now, and the painting is harmful to the body of painters, which leads to a great increase in the cost of steel structure painting
[0003] The salt spray resistance time of this kind of existing technology is uneven, and most of them are seriously low, only about 100 hours, which cannot meet the needs of industrial coatings and seriously restricts the application of water-based antirust primers

Abstract

The invention provides waterborne antirust and anticorrosion paint which comprises the following ingredients in parts by weight: 290-310 parts of base resin, 13-17 parts of a drier, 3-6 parts of a pH regulator, 2-5 parts of a dispersing agent, 1-3 parts of a defoaming agent, 1-3 parts of a thickening agent, 140-160 parts of ferric oxide powder, 280-320 parts of compound powder filler, 2-6 parts of a salt-fog resistance additive, 15-25 parts of a membrane forming agent, 0.1-0.2 parts of essence and 220-230 parts of deionized water. Additionally, the invention also provides a preparation method of the waterborne antirust and anticorrosion paint. According to the waterborne antirust and anticorrosion paint and the preparation method thereof, waterborne alkyd resin with excellent performance is taken as a membrane forming base stock, anti-rust pigment is selected, and a compound drying technology is adopted, so that the salt-fog resistance time is greatly prolonged to 800h, and the waterborne antirust and anticorrosion paint can be completely comparable with oil paint.

Description
