Anion coating solution for air purification

Abstract

The invention discloses an anion coating solution for air purification. The anion coating solution is prepared from, by weight, anion powder, distilled water, sodium polyacrylate, lauryl glucoside, glycol, 2-imidazolidone, citric acid, zinc oxide, lauryl betaine, tert-butyl acetate and a monoalkoxy-titanates coupling agent; nanoscale tourmaline powder, nanometer titania, sodium silicate, methyl alcohol and 2-alkyl acetamido ethyl imidazoline are added into a high pressure reaction kettle, the mass ratio of the nanoscale tourmaline powder to the nanometer titania, sodium silicate to the sodium silicate to the methyl alcohol to the 2-alkyl acetamido ethyl imidazoline is 1:(3-5):(1.5-2):(2-4):(3-5), and the prepared slurry mixed solution is subjected to a hydrothermal reaction. The anion coating solution can be thoroughly attached to the surfaces of pollutants, no dead corner exists during formaldehyde removal, the using effect is more obvious and more direct, the interfacial effect is larger, the toxic gas adsorption rate is further increased, the adsorptivity is stronger, and a formed nanometer film and the surface of an object are fused more directly.

Description

technical field [0001] The invention relates to the field of air purification coating liquid, in particular to an anion coating liquid for air purification. 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 carbon adsorption technology and ozone purification technology.

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.

For example, the catalytic active system in the photocatalyst adopts slurry impregnation and gel sol process to load TiO2 nanoparticles or thin films on the surface of the carrier and in the gaps to form a composite nanophotocatalyst, which is composed of a metal mesh fixed on an ultraviolet lamp. Although the catalytic reactor can remove indoor harmful gases very 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.
