Problems solved by technology

Although this freshener has a certain effect of fresh air, its effective time and bactericidal properties are relatively weak, and still need to be further improved; as the application number is 201110417810.3 Chinese patent discloses a kind of air freshener, which is composed of super absorbent resin, coloring agent, essence, surfactant, ethylene glycol, white carbon black, mint
However, because the formula contains superabsorbent resin, the freshener will absorb a large amount of moisture in the air in practical application and cause the air to dry, and the effect of freshening the air is relatively poor.

Description

technical field [0001] The invention belongs to the field of air fresheners, and in particular relates to an air freshener and a preparation method thereof. Background technique [0002] Air fresheners are also commonly known as environmental perfumes. The use of air fresheners can effectively improve air quality. Generally, there are three types: solid, liquid, and aerosol. Currently, there are many types of air fresheners on the market. Most of them use traditional ether and essence as raw materials, and use the low boiling point and volatile characteristics of ether to drive the essence. Diffuses in the air to mask unpleasant odors in the air. Although this freshener can effectively cover up the peculiar smell, it cannot really improve the air quality, because its components cannot decompose harmful gases, and it is difficult to really achieve the purpose of refreshing the air. After the human body inhales volatile ether with a certain fragrant gas, it is easy to produc...
