Nanometer deodorant for purifying air and preparing method thereof

Abstract

A nano-class deodoring agent for cleaning air is prepared from TiO2 nanoparticles, tourmalinite nanoparticles, muscovite nanoparticles, sodium silicate, sodium benzoate, sodium chloride, polyacrylamide, hydroxyethylene cellulose and propanetriol through ball grinding and baking. Its advantages are high effect to remove benzene, ammonia and formaldehyde by 60-80%, and short time (24hr).

Description

technical field [0001] The invention relates to an air purifier, in particular to a nanometer deodorant for air purification and a preparation method thereof, belonging to the field of nanotechnology. Background technique [0002] With the improvement of people's living standards, interior decoration has spread throughout urban and rural areas, but various decorative materials used for decoration, such as: plywood, paint, plastic products, floors, cement, etc., contain volatile harmful substances to varying degrees, and the main indoor air pollution is toxic. Harmful molecules include formaldehyde, benzene, ammonia, etc. Indoor pollution has become one of the top killers of human health. Therefore, how to purify indoor air in an all-round way in the shortest possible time has become a top priority. At present, the measures to purify the air include: negative ion generator dust removal technology, high-voltage electrostatic purification, activated c...

AI Technical Summary

Problems solved by technology

Based on the above air purification technologies, generally only harmful substances can be adsorbed and stored, but cannot be converted. Some measures such as negative ions and high-voltage electrostatic purification technologies can remove smoke and dust well, but it is difficult to purify pollution caused by chemicals and microorganisms.

Chinese Patent No. 02112266.0 discloses a nanocomposite photocatalyst for air purification, which is based on the catalytic activity system in the photocatalyst using slurry impregnation and gel sol processes to incorporate TiO 2 Nanoparticles or films are loaded on the surface of the carrier and in the voids to form a composite nanophotocatalyst. This patented technology is to use a metal mesh to fix the ultraviolet lamp to form a catalytic reactor. Although it can remove harmful gases in the room well, its use is relatively limited. , its function only works in a certain part of the indoor space, and it cannot quickly solve the problem of eliminating formaldehyde, benzene, ammonia and other harmful gases in the living room.
