Problems solved by technology

[0003] However, water-based paints also have certain defects. For example, the water-based wood white finish currently on the market faces the problem that the surface is easily polluted. These pollutants can erode the paint film and make it discolored, and at the same time produce some surface defects, which in turn affect the paint film. Appearance, which in turn restricts the application of water-based wood paint

Abstract

The invention discloses high-stain-resistance waterborne top coating, a preparation method thereof, application of the top coating, and woodware, and belongs to the technical field of coating. The topcoating includes the following components by weight: a water-based emulsion, water-based resin, a defoamer, a wetting agent, white paste, wax powder, a film-forming aid, a defoaming agent, a levelingagent, a rheological aid and water. The white paste includes the following components by weight: water, a dispersant, a defoamer, titanium dioxide, a water-based rheological aid, and a pH regulator.According to the top coating, water is adopted as a solvent, VOC emission in the system is extremely low, and the top coating is almost free of irritating odor, and is non-flammable, safe, stable, good in environmental protection performance, and good in stain resistance. The water-based resin and the water-based emulsion are mixed so that the crosslinking degree of the coating is further increased, hydrophobic aids are added, facilitating improvement in stain resistance and water resistance of coating films and further improving hardness and adhesive force of the coating films.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a highly stain-resistant water-based finish paint and its preparation method, application and woodware. Background technique [0002] With the changes of the times and the continuous development of the economy, people pay more and more attention to environmental protection and health issues. Although traditional solvent-based paints have good performance, because they use a large amount of organic solvents, these solvents will volatilize into the air, so they will produce a strong pungent smell, and at the same time pose a threat to human health, which violates the sustainable The concept of development and environmental protection. The water-based paint with water as the dispersion medium has been paid attention to by people. It is an ideal product to replace the traditional solvent-based paint and is in the stage of vigorous development. Compared with traditional paints, wat...
