Abstract

The invention discloses an air purification material capable of removing formaldehyde, acetaldehyde, acetic acid and ammonia and a preparation method of the air purification material. The preparation method comprises: performing acidizing treatment, washing and drying of an air purification material carrier to prepare an acidized air purification material carrier; mixing water, hydroxylammonium chloride, hexamethylene tetramine, chitosan, and orotic acid according to a mass ratio of 10:0.5-1.0:0.2-0.4:0.05-0.12:0.1-0.3 to prepare a mixed solution; and soaking the acidized air purification material carrier into the mixed solution for reaction, and drying the obtained product after reaction to obtain the air purification material. The air purification material provided in the invention has an excellent adsorption effect on formaldehyde, particularly has a preferable removal effect on low-concentration formaldehyde, and further has an excellent removal effect on acetaldehyde, acetic acid and ammonia. The air purification material is convenient to use, simple in preparation process, and good in practicality.

Description

technical field [0001] The invention relates to an air purification material and a preparation method thereof, in particular to an air purification material capable of simultaneously removing formaldehyde, acetaldehyde, acetic acid and ammonia and a preparation method thereof . Background technique [0002] People spend more than 80% of their time indoors on average every day, and the relationship between indoor air quality and human health is quite close. In recent years, the problem of indoor environmental pollution has become increasingly prominent, endangering human health, reducing the quality of life, affecting work efficiency, and reducing human immunity. [0003] The most prominent pollutants in indoor environmental pollution are formaldehyde and acetaldehyde. Floor leather, floor tiles, chemical fiber carpets, plastic wallpapers, thermal insulation materials, urea-formaldehyde resin adhesives, and fiberboards made of adhesives are commonly used indoors. , Plyw...
