Problems solved by technology

Ozone has a strong irritating taste, which can damage the soft tissues of the human body such as the respiratory mucosa; in addition, the strong oxidizing properties of ozone can reduce the quality of fruits and vegetables and reduce the content of reducing substances such as vitamin C, which is not conducive to food preservation
Such titanium dioxide sterilization products using photocatalysts require refrigerators to be equipped with ultraviolet lamps, and the products are generally sprayed on surfaces such as activated carbon, which are easy to fall off

preparation example Construction

[0037] The preparation method of this bactericidal air cleaner comprises the following steps:

[0038] (1) Preparation of medical stone particles loaded with nano-zinc oxide

[0039] Mix medical stone powder and nano-zinc oxide, dry granulate, and extrude to obtain medical stone particles loaded with nano-zinc oxide;

[0040] (2) Preparation of antibacterial and bactericidal solution

[0041] 1) Preparation of nano-silver dispersion: hydrolyze starch with amylase, mix the resulting precipitated product with water, heat to 65°C-75°C, then add polyethylene glycol, oscillate, then add nano-silver, oscillate to obtain nano-silver dispersion liquid;

[0042] 2) Preparation of monoglyceride laurate solution: Dissolve agar in hot water at 80°C to 99°C to make an agar colloid solution. When the solution is cooled to 45°C to 55°C, add monoglyceride laurate and mix evenly. Obtain monoglyceride laurate solution;

[0043] 3) Prepare the antibacterial and bactericidal solution: mix the...

Embodiment 1

[0055] 1. Preparation of medical stone particles loaded with nano zinc oxide

[0056] Mix 10 parts of medical stone powder with a particle size of 0.1 mm and 0.2 parts of nano-zinc oxide, dry granulate, and extrude to obtain medical stone particles loaded with nano-zinc oxide.

[0057] 2. Preparation of antibacterial and bactericidal solution

[0058] 1) Preparation of nano-silver dispersion: hydrolyze starch with amylase (based on 10 parts of starch, amylase is 2000U), shake and react at 50°C for 18-20h, add lye to terminate the reaction, centrifuge, pour off the supernatant, Add 100 mL of deionized water to the obtained precipitate, heat to 70°C, then add 0.5 parts of polyethylene glycol, shake, then add 0.5 g of nano-silver, and shake to obtain a nano-silver dispersion;

[0059] 2) Preparation of monoglyceride laurate solution: dissolve agar in 100mL hot water at 90°C to make an agar colloid solution with a concentration of 1.5%. When the solution is cooled to 50°C, add 0....

Embodiment 2

[0065] The bactericidal air cleaner of embodiment 2 is different from embodiment 1 in that when tourmaline powder and medical stone particles are mixed, the tourmaline powder used is 30 parts, and the medical stone particles loaded with nano-zinc oxide are 40 parts, and all the other are the same as those in the implementation. Same as Example 1.

Abstract

The invention discloses a sterilizing air purifying agent as well as a preparation method and application thereof. The sterilizing air purifying agent comprises a surface layer and a core layer, wherein the surface layer is a bacteriostatic and bactericidal membrane containing glycerol monolaurate, and the core layer is a mixture of tourmaline powder and nano-zinc oxide-loaded medical stone particles. Furthermore, the invention also discloses the preparation method of the sterilizing air purifying agent and application of the sterilizing air purifying agent in refrigerator sterilization and air purification. The sterilizing air purifying agent provided by the invention is safe and non-toxic, and can be used for spaces such as domestic refrigerators which have the demands of sterilization and air purification. The air purifying agent can effectively inhibit the production of extracellular toxins by bacteria; the air purifying agent can kill gram-positive bacteria, gram-negative bacteriaand the like, and the sterilization rate can reach 99%; the air purifying agent can generate negative ions so as to play a role of air purification.

Description

technical field [0001] The invention relates to a bactericidal air purifier and its preparation method and application. Background technique [0002] Refrigerators have become an important household appliance for food preservation in daily life. Storing food in the refrigerator can ensure the freshness of ingredients, prolong the shelf life of food, and prevent food from spoiling too quickly. However, the space environment of the refrigerator is not clean. Air, raw and sparse food are carriers of microorganisms such as bacteria, which can be brought into the refrigerator. The low-temperature environment in which the refrigerator operates can only delay the reproduction and division of microorganisms. Studies have pointed out that there are a large number of microorganisms in the refrigerator, 17% of which are pathogenic bacteria, and staphylococci are the main pathogenic bacteria, mainly S. haemolyticus, S. hominis Staphylococcus lyte (S.arlettae), Staphylococcus goatum (S....
