Abstract

The invention discloses a water-based nanometer titanium dioxide photocatalytic sterilization purification coating and a preparation method thereof. The coating is prepared from 38-55 wt% of nanometertitanium dioxide, 10-30 wt% of a waterborne organosilicone modified acrylic emulsion, 2-5 wt% of silicate, 1.5-3.5 wt% of an inorganic antibacterial agent, 1-3 wt% of negative ion micro-powder, 1.4-5.0 wt% of a functional assistant, 2-4 wt% of a silane coupling agent, 0.4-0.8 wt% of a wetting dispersant, and the balance of water. The coating has air purifying and bacterium killing effects, is green and environmentally friendly, has excellent anti-aging property, scrub resistance, cohesiveness, corrosion resistance and the like, can directly replace putty powder and a latex paint, and can be directly firmly bonded with a cement mortar wall without peeling, shedding or cracking.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a water-based nano-titanium dioxide photocatalytic sterilization and purification coating and a preparation method thereof. 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 m...
