Abstract

The invention discloses an air purification material capable of removing formaldehyde, acetaldehyde, acetic acid and ammonia and a preparation method thereof. The air purification material carrier is subjected to acidification treatment, washed and dried to obtain an acidified air purification material carrier, and water, hydroxylamine chloride, hexamethylenetetramine, chitosan, and orotic acid are mixed in a mass ratio of 10:0.5~ 1.0: 0.2~0.4: 0.05~0.12: 0.1~0.3 mixed to obtain a miscible solution, the acidified air purification material carrier is immersed in the miscible solution for reaction, and dried after reaction to obtain the Air purification material. The air purification material provided by the present invention has a good formaldehyde adsorption effect, especially still has a good removal effect on low-concentration formaldehyde, and also has a good removal effect on acetaldehyde, acetic acid and ammonia, and is easy to use and easy to prepare The process is simple and the practicability is strong.

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] On average, people spend more than 80% of their time indoors every day, and indoor air quality is closely related to human health. In recent years, 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 of indoor environmental pollution are formaldehyde and acetaldehyde. Commonly used indoor floor leather, floor tiles, chemical fiber carpets, plastic wallpaper, thermal insulation materials, urea-formaldehyde resin adhesives and fiberboards made of this adhesive Furniture made of, plywood, etc. can release formaldehyde....
