Problems solved by technology

[0003] In addition, for family bathrooms, due to the tight sealing and poor air flow, most bathroom sewer pipes do not have sealing devices, even if there is a sealing effect, it is not very ideal, resulting in odors in the bathroom. These odor components are mainly hydrogen sulfide, ammonia, and sulfur dioxide. etc. These gases not only affect human health, but also affect human living environment and quality of life
Most of the deodorants currently in use are plant extraction or chemical synthesis. The plant extraction process is complicated, the production cost is high, and the people are not easy to accept; whether chemical synthesis is harmful to the human body, whether there is secondary pollution, or whether it has corrosion is unknown.

Abstract

The invention discloses a preparation method of a mixed nanometer starch deodorant. The preparation method comprises the following steps: (1), weighing amylose and amylopectin according to a ratio of20-1 to 1:20, dissolving in dimethyl sulfoxide, and then slowly dropwise adding (100-1000)mL of ethanol to obtain a precipitate A; (2), drying and gelatinizing the precipitate A, dropwise adding (10-1000)mL of ethanol, stirring, and centrifuging to obtain mixed nanoparticles B; (3), ultrasonically washing the obtained mixed nanoparticles B to obtain the mixed nanometer starch deodorant. The mixednanometer starch deodorant prepared by the preparation method uses raw materials which are wide in sources and easy to obtain, is low in cost and good in effect, can effectively remove odor, and is environment-friendly and free of any side effects; by the preparation method of the mixed nanometer starch deodorant, the conditions are mild, the procedures are simple, the cost is low, and environmentfriendliness is achieved.

Description

technical field [0001] The invention relates to a preparation method of a deodorant, in particular to a preparation method of a mixed nano starch deodorant. Background technique [0002] The so-called mixed nano-starch deodorant is an environmentally friendly product, which has excellent enzyme-producing properties, can effectively capture and degrade odor-causing substances, and convert them into benign cellular components and odorless carbon dioxide and water. Mixed nano-starch deodorant is widely used in organic waste treatment, for example: it can be used in sewage treatment, which can effectively degrade the odor produced by sewage; landfill, can effectively degrade the odor produced by garbage; pet deodorization: can effectively decompose pets The peculiar smell emitted; can quickly remove the peculiar smell of smoke and leather in a certain space; can effectively control the peculiar smell in the room (home, hotel, club, etc.), and provide long-term odor control by re...
