Abstract

The invention discloses a biological formaldehyde-removing air freshener and a preparation method thereof. The biological formaldehyde-removing air freshener comprises the following components in parts by weight: 4-6 parts of an unfermented green tea water extract, 4-6 parts of a wild chrysanthemum water extract, 4-6 parts of a ginkgo leaf water extract, 4-6 parts of a lauraceae bark water extract, 2-4 parts of a wild buckwheat water extract and 0.1-1 part of an antiseptic bacteriostatic agent. According to the biological formaldehyde-removing air freshener provided by the invention, the unfermented green tea water extract, the wild chrysanthemum flower water extract, the ginkgo leaf water extract, the lauraceae bark water extract, the wild buckwheat water extract and the antiseptic bacteriostatic agent cooperate with one another, so that the formaldehyde absorption and removal rate can reach 90% or above. A traditional air freshener with the purpose of covering peculiar smell is broken through, and the core concept of making a subtraction on air is innovatively provided on the basis of the design concept of the air freshener. The biological formaldehyde-removing air freshener is used for cleaning air and efficiently removing air pollutants such as formaldehyde and the like.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a biological aldehyde-removing air freshener and a preparation method thereof. Background technique [0002] With the development of economy and society and the improvement of material living standards, interior decoration is becoming more and more beautiful, and people have higher and higher requirements for indoor environment. Indoor air fresheners have gradually become a must-have item for home use, and the market for air fresheners has developed rapidly. However, currently commercially available air fresheners are mainly composed of ethanol, propane, butane, dimethyl ether, essence and other components. What's more serious is that these chemical substances contained in traditional air freshener products themselves or the gases (such as ethers) produced after decomposition in the air are also a class of air pollutants. As a result, long-term use of air fresheners ...
