Problems solved by technology

[0002] In recent years, people's demand for interior wall coatings has become more and more personalized and functional. The existing latex paint film is soft, has poor stain resistance and scratch resistance, and the paint film is easily scratched, and its functionality is not outstanding enough.
At the bottom of the kitchen or living room walls of many families, most families use ceramic tiles for decoration due to stains or hard objects; ceramic tiles consume a lot of energy and are expensive, resulting in the accumulation of waste tiles after renovation, which seriously pollutes the environment
In addition, due to gravity, the tiles are easy to fall off the wall and hurt people

Embodiment 1

[0050] A water-based scratch-resistant coating, which is prepared from the following raw materials in parts by weight:

[0051]

[0052]

[0053] The preparation method of the water-based scratch-resistant coating of the present embodiment is as follows:

[0054] (1) Premixing: Add 17 parts by weight of water in the dispersion tank, then add the above dispersant, wetting agent, 0.2 parts by weight of defoamer, film-forming aid, antifreeze and cellulose thickener, After fully mixing evenly, a gel-like substance is formed to facilitate the dispersion of pigments and fillers. The mixing speed is controlled at 300-500rpm;

[0055] (2) Grinding and dispersing: Add titanium dioxide, ceramic microbeads, and quartz powder into the dispersing tank, beat and grind for 20 to 25 minutes at a speed of 2000 to 3000 RPM, and check that the fineness of the slurry is less than 45um. The particles are dispersed into primary particles under the high shear rate of high-speed agitation, and...

Abstract

The invention discloses a waterborne scratch-resistant coating, which is prepared from the following raw materials in part by weight: 6 to 10 parts of ceramic mirobeads, 6 to 14 parts of quartz powder, 30 to 40 parts of silicone acrylic emulsion, 0.4 to 0.7 part of dispersing agent, 0.1 to 0.3 part of wetting agent, 0.2 to 0.6 part of defoaming agent, 1.5 to 2 parts of film forming aid, 0.1 to 0.4 part of thickening agent, 0.3 to 0.5 part of levelling agent, 0.1 to 0.2 part of scratch-resistant aid, 0.1 to 0.4 part of fluorine aid, 20 to 23 parts of titanium white and 20 to 25 parts of water.The ceramic mirobeads, the quartz powder and the scratch-resistant aid are added, so that the compactness of a film is improved, the hardness and surface smoothness of the film are improved, and the film has high scratch resistance, wear resistance and resistance to soiling, and has a smooth handfeel like a glass surface.
