Abstract

The invention relates to the technical field of paints for indoor decoration and particularly relates to a water-based paint capable of purifying air. The water-based paint comprises 20-65 percent of water-based polyurethane emulsion, 20-35 percent of talcum powder, 1-5 percent of anatase titanium dioxide, 0.5-1 percent of photocatalysis additive, 1-2 percent of wetting agent, 0.5-1 percent of dispersant, 1 percent of preservative, 1-2 percent of antifreezing agent, 1-2 percent of film-forming agent and the balance of water. According to the water-based paint capable of purifying air, the photocatalysis additive, namely zinc oxide is added to the paint, so that the paint can obtain relatively high catalysis efficiency under visible light, and indoor organic pollutants can be effectively degraded.

Description

technical field [0001] The invention relates to the technical field of coatings for interior decoration, in particular to a water-based coating capable of purifying air and a preparation method thereof. Background technique [0002] Formaldehyde is contained in paints such as wood, boards, furniture, walls, etc. in the family room, but what is even more frightening is that the release period of formaldehyde is generally three to fifteen years. The No. 153 Bulletin released by the World Health Organization in 2004 determined that formaldehyde is a carcinogenic and teratogenic substance. Formaldehyde is a recognized allergen, is also one of the potential strong mutagen, and is also one of the risk factors leading to childhood leukemia. According to domestic medical journals and related literature reports, the hazards of indoor formaldehyde to human health can be summarized as stimulating, toxic and carcinogenic. [0003] Photocatalytic technology has a wide range of applicat...
