Scrubbable barite photocatalyst spraying liquid

The invention discloses scrubbable barite photocatalyst spraying liquid. The main points of the technical scheme are that ingredients consist of barite, acidified attapulgite clay, high-viscosity attapulgite clay, nano-titanium dioxide, white carbon black, nano-silver-loaded antibacterial powder, nano-magnesium oxide, nano-zirconium dioxide, nano-aluminium oxide, nano-zinc oxide, polyvinyl alcohol, polyethylene glycol, polydimethylsiloxane and water. The scrubbable barite photocatalyst spraying liquid is prepared by stirring, dispersing, emulsifying and grinding the ingredients first, then performing dispersion again, and performing homogenization, grinding, and canning. The scrubbable barite photocatalyst spraying liquid is suitable to be sprayed onto the surface of a building or a decorative material, can continuously adsorb and degrade pollutants, such as formaldehyde, ammonia and benzene, under the irradiation of light, and has extremely good functions of sterilization, deodorization, mould prevention and air purification; a thin film which is formed by spraying the scrubbable barite photocatalyst spraying liquid onto the surface of the building or the decorative material can present a saturated state after being used for a long time, and can be scrubbed with a cleaning rag.
