Multieffect nano air purificant and preparation method thereof

Abstract

The invention provides a multieffect nano air purificant including the following components by part by weight: 1 to 5 parts of photocatalyst functional powder, 2 to 10 parts of nanometer silica, 0.1 to 0.3 part of inorganic antibacterial powder, 2 to 5 parts of propanediol, 0.3 to 1 part of sodium hexametahposphate, 0.5 to 5 parts of surface active agent, 0.5 to 4 parts of dimethyl silicone polymer and 70 to 100 parts of deionized water. The nano multieffect air purificant of the invention solves the problem of wideband of nano concatemer, develops visible photocatalyst materials, and can give play to the effectiveness of the photocatalyst thereof under the long wave light near 600nm, namely, under the irradiation of an indoor fluorescent lamp, the photocatalyst can still have high activity.

Description

technical field [0001] The invention relates to a purifying agent, in particular to a nanometer multi-effect air purifying agent capable of removing formaldehyde, antibacterial and purifying air and its preparation method, especially applied to indoor craft decorations, furniture, curtains, toys and other products. Background technique [0002] The pollution of interior decoration materials and furniture is the main aspect causing indoor air pollution at present. Materials such as paint, plywood, shaving filler, interior wall paint, and plastic veneer all contain organic vapors such as formaldehyde, benzene, ethanol, and chloroform, all of which are quite carcinogenic. [0003] Investigations by specialized agencies in the United States and Japan have found that the indoor air pollution of many civil and commercial buildings is 2-5 times that of outdoor air pollution, and about 30% of the homes cause "new home syndrome" due to the use of harmful chemicals. The World Health ...

Problems solved by technology

The use of these means can clean the air to a certain extent, but these products cannot fundamentally purify the indoor environment, especially for "indoor air killers" such as bacteria and microorganisms with the ability to reproduce, these products all exist. Single efficacy, short duration, odor, noise, repeated consumption and secondary pollution, etc.

These products cannot fundamentally achieve the purpose of permanent indoor purification

[0006] Moreover, traditional photocatalysts can only react when they are subjected to ultraviolet light with a wavelength shorter than 400nm, and cannot perform their functions in corridors and living rooms where sunlight cannot reach, so the utilization conditions are greatly restricted.
