Abstract

The invention discloses nano titanium dioxide photocatalytic disinfecting and purifying coating, made from, by weight, 38-55% of nano titanium dioxide, 10-30% of fluorocarbon emulsion, 2-5% of an inorganic porous material, 1.5-3.5% of a rare-earth antibacterial agent, 1-3% of an anion release agent, 1.4-5.0% of functional aids, 2-4% of titanate coupling agent, 0.4-0.8% of a wetting dispersant, andthe balance of deionized water. The nano titanium dioxide photocatalytic disinfecting and purifying coating has the functions such as air purifying and bacteria killing, is green, has excellent properties such as aging resistance, scrubbing resistance, adhesion, corrosion resistance, may directly replace putty powder and latex paint, may be directly bound to a cement mortar wall, and is firm andfree of skinning, separating and cracking.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano-titanium dioxide photocatalytic sterilization and purification coating. Background technique [0002] Paint is a new type of polymer material and supporting engineering material that is coated on the surface of the protected and decorated substrate and can form a continuous film that is firmly attached. It has a wide range of applications. At present, architectural coatings mainly play a decorative and protective role, and rarely involve antibacterial and air purification functions. [0003] At present, indoor air pollution is serious and increasing day by day. According to surveys in recent years, it has been found that indoor air pollution is more serious than outdoor. Indoor air pollution is affected by many factors. In addition to air pollution entering the room, there are also indoor pollution sources. Modern building materials, decoration materials, carpets, furn...
