Problems solved by technology

[0006] However, although the nano-air catalyst air purifiers used in the market today do not have the defects of formaldehyde capture agents and photocatalysts, they are more suitable for use as indoor air treatment products, but most of the nano-air catalyst air purifiers are effective in decomposing formaldehyde, removing The effect of organic chemicals such as TVOC and ammonia is not very satisfactory, the air purification rate is not high, and there is still a lot of room for improvement

Abstract

The invention provides a nanometer air catalyst air-cleaning agent capable of decomposing formaldehyde and removing volatile organic compounds, such as TVOC and ammonia, and a preparation method thereof. The nanometer air catalyst air-cleaning agent is prepared from the following components by weight percent: 0.4-5.5% of nanometer zinc oxide, 0.2-2.1% of glycol, 0.15-1.8% of n-butyl alcohol, 0.1-1% of chitosan and 89.6-99.15% of purified water. The preparation method thereof comprises the following steps: weighting nanometer zinc oxide, glycol, n-butyl alcohol, chitosan and purified water at weight percent; putting the nanometer zinc oxide and the purified water into a stirrer for fully stirring; adding glycol and n-butyl alcohol for fully stirring; adding chitosan and fully stirring till completely dissolving, thereby acquiring the nanometer air catalyst air-cleaning agent. The nanometer air catalyst air-cleaning agent can effectively decompose formaldehyde and remove the volatile organic compounds, such as TVOC and ammonia and can increase the air purifying rate.

Description

technical field [0001] The invention relates to an air purifier, in particular to a nanometer air catalyst air purifier capable of decomposing formaldehyde and removing volatile organic substances such as TVOC and ammonia and a preparation method thereof. [0002] technical background [0003] With the development of the economy, people have become rich, and their awareness of the quality of living and safety has been greatly improved. Newly renovated houses, offices, and school classrooms are no longer simply ventilated for a while to move in and use, but focus on scientific data. Using modern high-tech products to control the air quality of the newly decorated interior, TV and newspapers often report that living in an environment with excessive formaldehyde for a long time causes physical discomfort, and even has cancer, leukemia and other diseases. All use of environmentally friendly building materials and furniture may also cause formaldehyde to exceed the standard due to...
