Abstract

The invention discloses a solid air freshener with a formaldehyde removal effect and a preparation method thereof. The air freshener is clean and nontoxic, does not contain organic aromatic polymers,and is prepared from the following raw materials: carrageenan, gelatin, mint, orange peel, ethanol and Luotingshi. The preparation method comprises the following steps that the carrageenan and the ethanol are mixed, stirred, and heated to boil to form clear and transparent liquid, when the liquid is cooled to be about 70 DEG C, a spice extract and the Luotingshi are added, uniform stirring is conducted, a mixture is pouring into a mold while the mixture is hot, and cooling is conducted to obtain a gel product. The raw materials of the synthesized air freshener are all pure natural raw materials, so that the air freshener is harmless and has the effect of removing formaldehyde.

Description

technical field [0001] The invention relates to the field of air fresheners, in particular to an air freshener synthesized from pure natural raw materials and having the effect of removing formaldehyde. Background technique [0002] Air fresheners have been used as chemical products in the field of environmental sanitation since the 20th century. Air fresheners are also called environmental perfumes. The fragrance from the air freshener spreads into the air to cover up the odor, so as to reduce people's sensitivity to the odor. The most direct is the aerosol type and spray type currently used, allowing the fragrance to be sprayed directly into the air to achieve the effect of purifying the air. . [0003] Aerosol-type and spray-type air fresheners need to react with organic matter or sulfide to make them spray out. These substances themselves have certain toxicity. Therefore, compared with aerosol-type and spray-type air fresheners, solid air Fresheners are more advantageo...
