Abstract

The invention discloses a photocatalyst paint, consisting of the following raw materials according to weight percentage: 0.5-1.5 percent of nanometer titanium dioxide, 0.05-0.15 percent of nanometer titanium phosphate, 0.05-0.15 percent of nanometer silicon dioxide, 0.5-1.5 percent of nanometer negative ion powder, 5-15 percent of emulsion used for construction coatings, 0.001-0.004 percent of defoaming agent, 0.001-0.004 percent of coupling agent, 0.001-0.004 percent of dispersant, 0.01-0.04 percent of thickener and the rest of water. The paint can purify air in a rapid, efficient and lasting manner, completely remove interior odor and harmful gases such as formaldehyde, TVOC, benzene, ammonia and the like, and inhibit or kill microorganism; furthermore, the preparation equipment and technology are simple, the production cost is low, the product is harmless and odorless, safe, environment-friendly and applicable to various interior environments such as newly decorated rooms, office places, hotels, stores, and the like.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a photocatalyst coating. Background technique [0002] People spend more than 80% of their time indoors, and indoor air quality greatly affects people's quality of life, health and work efficiency. In recent years, indoor air pollution and the health problems caused by it have begun to receive widespread attention. There are many reasons for indoor air pollution, mainly including chemical pollution and microbial pollution. Chemical pollution mainly includes formaldehyde, total volatile organic compounds (TVOC), benzene, and ammonia pollution, mainly from artificial boards, paints, coatings, wallpapers, adhesives, new furniture, and synthetic textiles used in building materials and interior decoration. The survey report shows that more than 60% of the newly renovated houses in major cities in my country have excessive formaldehyde, TVOC and benzene pollution, especially formalde...
