Abstract
The invention relates to a preparation method of a nano material used for disinfecting and removing formaldehyde. The preparation method comprises following steps: titanium dioxide solution is added into a solvent for sufficient stirring; and nano silver solution is added into the mixture for sufficient stirring so as to obtain the nano material used for disinfecting and removing formaldehyde. The nano material can be sprayed on furnitures, in rooms, in offices, or in public places, and is high in disinfection ability, simple in construction and low in cost. In addition, problems of traditional materials used for disinfecting and removing formaldehyde are solved, wherein the problems are that, the traditional materials are just capable of covering the peculiar smell, and are not capable of disinfecting or removing formaldehyde completely. The nano material comprises following ingredients, by mass, 1 to 8 % of anatase titanium dioxide, 0.5 to 2% of silver nitrate, 0.5 to 2% of a reducing agent, 0.2 to 1.3% of gellan gum, 2.5 to 4% of a surfactant, 1.5 to 3% of an adjuvant and 79.7 to 93.8% of 75% alcohol.
