Abstract

The invention provides a composite air purifying preparation containing nanometer mineral substances, which comprises the following components in percentage by weight: 47-78% of attapulgite as natural mineral, 20-50% of artificial zeolite molecular sieve as molecular sieve, 0.5-5% of sodium hydrogensulfite as a modifier, 0.5-5% of aluminum sulfate as foaming agents and 0.5-2% of cetyltrimethylammonium chloride as surfactants, 0.2-2% of nanometer photocatalyst titanium dioxide colloidal solution as a photochemical catalyst; and the air purifying preparation is prepared by the method comprising the following steps: purification, modification, activation, primary drying, primary pelleting, secondary drying, secondary pelleting, third drying, roasting, sieving and inspection of the finished product and packaging. The product of the invention has extremely selective adsorption capability of organic pollutants in the air, and has the advantages of strong preferential adsorption capability and high decomposition efficiency, environment-friendly craft, low cost, volume production fitness and the like.

Description

technical field [0001] The invention belongs to the technical field of air purification, and specifically relates to a composite air purifier containing nano-minerals produced by selecting natural mineral materials and photocatalyst materials and adopting a semi-dry method for modification and activation and a preparation method thereof. Background technique [0002] According to the report provided by the World Health Organization, the number of premature deaths due to urban pollution in the world has exceeded 750,000, including 530,000 in Asian countries and regions. The number of people suffering from air pollution is even more numerous. At present, the problem of air pollution in my country's cities is still prominent. 44.9% of the urban ambient air is lower than the national second-level standard, and 43 cities' ambient air quality is lower than the national third-level standard. According to experts, 30% of the world's new and reconstructed buildings contain harmful ind...
