Attapulgite refrigerator deodorization particle and preparation method

Abstract

The invention discloses an attapulgite rod refrigerator deodorization particle and a preparation method, and belongs to the technical field of attapulgite. The particle is prepared from the following ingredients: high-viscosity attapulgite clay, pasty attapulgite clay, thermally modified attapulgite clay, activated carbon, white carbon black, folium artemisiae argyi, rhizoma atractylodis, licorice root, rhizome of acorus calamus, clove oil, tea tree essential oil and herba menthae essential oil. The preparation method comprises the following steps: weighing, smashing and mixing the traditional Chinese medicines to obtain a traditional Chinese medicine mixture, and extracting in a Soxhlet extractor to obtain extracting solution; mixing and evenly stirring the high-viscosity attapulgite clay, the pasty attapulgite clay, the thermally modified attapulgite clay and the activated carbon, then, adding the extracting solution and the essential oil into mixed materials, evenly stirring and applying ultrasound; adding the white carbon black into the mixture, drying after evenly mixing, and carrying out granulation to obtain the attapulgite refrigerator deodorization particle. The attapulgite refrigerator deodorization particle has an efficient deodorization effect and a certain sterilizing effect. The preparation method is simple and practicable, and has a good application value.

Description

technical field [0001] The invention relates to the technical field of attapulgite, in particular to an attapulgite refrigerator deodorizing granule and a preparation method thereof. Background technique [0002] Refrigerators have become an essential and commonly used electrical appliance in modern families. It is usually used to store food raw materials and vegetables to keep the quality and freshness, and it plays an indispensable role in daily life. After long-term use, it is inevitable to lose some food residues in the refrigerator. These nutritious substances are also the breeding grounds of microorganisms, so that various bacteria and viruses in the refrigerator pose a certain threat to the quality of food, and thus pose a certain safety hazard to human health. These microorganisms also produce some harmful substances to the human body, such as ammonia, amines, and even carcinogens such as Aspergillus flavus. Mold, yeast, etc. are more common pathogens in refrigera...

Problems solved by technology

These refrigerator deodorants and odor absorbers have their own characteristics. After repeated practice, the commonly used refrigerator deodorizers and odor absorbers are analyzed: calcium chloride and calcium oxide have better moisture absorption and odor absorption performance, but due to the relatively high humidity in the refrigerator Calcium chloride becomes liquid after absorbing moisture, which is easy to contaminate food in the refrigerator; calcium oxide becomes powder after absorbing moisture, which is also easy to contaminate food in the refrigerator; activated carbon and bamboo charcoal are also effective, but once they absorb moisture It is easy to agglomerate, which affects the adsorption effect, cannot continue to deodorize, and has black dust, forming secondary pollution, so it cannot be popularized and applied
