Problems solved by technology

After a market survey, it was found that the latex paint for interior walls currently on the market generally has the weakness of poor stain resistance. Once the decorated wall has stains, the wall cannot be completely cleaned, or it cannot be kept clean for a long time, and local repairs are required. There will be obvious chromatic aberration problems when

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a self-cleaning and decontaminating latex paint for interior walls, a preparation method and a coating method thereof. Background technique [0002] At present, with the increasing number of interior wall materials for building decoration, beautiful wallpapers and easy-to-clean tiles have become more and more popular among mid-to-high-end users, while the competitive advantage of traditional interior latex paint has gradually weakened. After market research, it is found that the latex paint for interior walls currently on the market generally has the weakness of poor stain resistance. Once the decorated wall has stains, the wall cannot be completely cleaned, or cannot be kept clean for a long time, and local repairs are required. There will be obvious chromatic aberration problems. Contents of the invention [0003] In view of the defects in the above-mentioned prior art, the purpose o...
