  • Solid material for purifying air and preparation method and use thereof
    Patent number: 12121856
    Abstract: The invention provides a solid material for air purification and disinfection and a preparation method and application thereof. The solid material includes: 50-60 wt. % of inorganic porous materials, 10-20 wt. % of nano titanium dioxide, 3-5 wt. % of fluorescent materials, 20-30 wt. % of sodium chlorite, 3-5 wt. % of sodium lignosulfonate, 1-10 wt. % of polyethylene glycol, and 1-10 wt. % of polyvinyl alcohol. The method for preparing the solid material includes: formulating the fluorescent material into a slurry by using a polyethylene glycol aqueous solution; uniformly mixing the nano titanium dioxide, the sodium lignosulfonate, and the fluorescent material formulated into the slurry, and then spraying the mixture on an inorganic porous material carrier to be uniformly adsorbed; and mixing the sodium chlorite with the above mixture for granulation to obtain the product.
