Problems solved by technology

[0002] At present, there are many kinds of water-based anti-corrosion coatings on the market, but they generally have the disadvantage of low solid content, which will increase the cost of manufacturers. Therefore, the development of anti-corrosion coatings with high solid content is the focus of scientific researchers; in addition , the function of a single system of anti-corrosion coatings is relatively single, and there are some shortcomings in application; the compactness of water-based coatings also needs to be improved, so as to improve the mechanical properties of coatings; water-based coatings have higher requirements on the cleanliness of the substrate surface and the construction process , due to the high surface tension of water, dirt is easy to cause shrinkage of the coating film, and the disp
