The invention provides a triple-effect all-weather photocatalyst
indoor air purifying agent as well as a preparation method and application thereof and relates to the field of
air purification of living rooms, offices, public facilities, transportation means and the like. The
indoor air purifying agent is prepared from the following raw materials: 0.5 to 5 parts of nano-grade
anatase type titaniumdioxide, 1 to 8 parts of nano pore-
diameter diatomite, 3 to 30 parts of
persimmon extract, 0.5 to 5 parts of octylisothiazolinone, 0.5 to 5 parts of dispersant and 200 to 350 parts of de-ionized water. The
indoor air purifying agent provided by the invention has sterilization and
mildew prevention, deodorization, self-cleaning,
formaldehyde, tribenzene, chlorinated gas purification functions andthe like, and has high purification efficiency; the indoor air purifying agent can be used for effectively degrading harmful gas in the air and killing various
bacteria and can be used for carrying out
decomposition and harmless treatment on toxins released by
bacteria or fungi. The preparation method has a simple technology and is suitable for industrial production. The application of the indoorair purifying agent is to spray the indoor air purifying agent on the surface of an object and a very thin transparent
coating film is formed on the surface of the object.
