Abstract

The invention discloses an air-purification environment-friendly paint and a preparation method thereof. By using a water-based fluorocarbon resin emulsion as a film forming matter and an anatase sulfur/lanthanum-codoped nano titanium dioxide photocatalyst as an addition component of the paint, the air-purification internal wall paint with excellent self-cleaning property is prepared. The paint has the advantages of favorable scrub resistance, high adhesion, high paint film fullness, environment friendliness and excellent air purification photocatalytic performance, and has antimicrobial and moldproof functions. Under the irradiation of visible light, the catalytic degradation purification rate for formaldehyde and other gaseous pollutants caused by interior decoration can reach 80% above; and under the condition of no lighting, the sterilization rate for Staphylococcus aureus in the environment can reach 98% above.

Description

technical field [0001] The invention relates to the technical field of air-purifying coatings, in particular to an air-purifying and environmentally friendly coating that uses water-based fluorocarbon resin emulsion as a film-forming substance and anatase-type sulfur-lanthanum co-doped nano-titanium dioxide coatings doped with photocatalysts and its Preparation. Background technique [0002] With the development of my country's economy and society, people's living standards continue to improve, and people pay more and more attention to home environment decoration. However, due to the use of resins and adhesives in various indoor decoration materials and furniture, harmful substances contained in them are released. It will cause indoor air pollution. Pollutants in the air mainly include organic volatiles such as formaldehyde, toluene and xylene, among which formaldehyde has the greatest impact on human health. Solving indoor environmental pollution has become a hot spot that...
