Abstract

The invention discloses a formaldehyde-removing air purifying agent and a preparation method thereof. The formaldehyde-removing air purifying agent comprises the following components: an active deodorant, a surfactant, a plant extract or a plant extract microcapsule, a preservative, a propellant and water. The formaldehyde-removing air purifying agent disclosed by the invention can quickly and continuously capture and decompose harmful gases such as formaldehyde and ammonia gas in the environment, is good in purifying effect, and also has good sterilization, anti-oxidation and refreshing effects.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a formaldehyde-removing air purifier and a preparation method thereof. Background technique [0002] The volatilization and release of harmful components such as formaldehyde remaining in the process of home decoration seriously endanger human health. In addition, when the indoor environment is poorly ventilated and the air flow is not good, the presence of microorganisms will also produce peculiar smells, especially hydrogen sulfide and ammonia in the bathroom, which will affect the living environment and quality. Air fresheners, deodorants, etc. can achieve air purification and freshness by absorbing and degrading harmful gases and covering up odors. Chinese patent CN103690983A discloses a plant extract air purifier, which is prepared from the following components: plant extract tea polyphenol, plant extract sodium lignosulfonate, plant extract percarbamide, plant ext...
