Problems solved by technology

The main disadvantage of this kind of coating is that the elasticity of the coating film is easy to age, the hardness is not good, and it cannot effectively protect the strength of the bottom layer of the wall, resulting in cracking and falling off of the wall surface, which not only affects the appearance of the building, but also cracks on the wall surface, causing the wall surface to crack and fall off. water leakage

Abstract

The invention discloses waterborne coating, which contains waterborne polyurethane resin, acrylic ester, tung oil, titanium dioxide, polyvinyl alcohol, light calcium carbonate, talcum powder, gypsum powder, titanium dioxide, silane compound, guar gum, fluororesin, waterborne epoxy modified resin, acrylate emulsion, Mn, Cr, Ni, Zn, Cu, Mo, Ti, Pd, Pt, Au, W, Ta, Nd, Ce, Eu, Lu and balance of water. As the waterborne coating contains the components like Ni, Zn and Ti, the waterborne coating has performance of high temperature resistance and corrosion resistance, and is adapted to the coating requirements of various occasions; moreover, the waterborne coating disclosed by the invention does not contain toxic organic solvent, is free of pollution and also has the advantages that the coating cannot be cracked, ageing resistance is high and adhesive force is powerful.

Description

technical field [0001] The invention relates to a water-based paint and a preparation method thereof, belonging to the technical field of paint. Background technique [0002] In recent years, from the viewpoint of environmental problems, the transition from organic solvent-based paints to water-based paints has been progressing. In addition, coatings are generally required to have excellent coating properties such as water resistance, alkali resistance, abrasion resistance, and weather resistance. [0003] Water-based coatings are coatings that use water as a dispersion medium and thinner. Compared with organic solvent-based coatings, water-based coatings not only reduce the emission of volatile organic solvents, but also save resources and energy (energy consumption is required to produce solvents), and are convenient. Transport and storage. With the enhancement of people's awareness of environmental protection, the relevant environmental protection regulations on the pro...
