Description

TECHNICAL FIELD

[0001] The present application relates to the field of air purification technology, in particular to an air purification agent and a preparation method and use method thereof. BACKGROUND

[0002] With the improvement of people's living standards, the requirement for the environment is also getting higher and higher, and more and more air purification products enter people's life. At present, there are many air purification products on the market, and the principle is to utilize the strong oxidizing property of chlorine dioxide to oxidize and reduce many organic and inorganic substances in the air, including organic sulfides, organic amines, phenols, aromatic hydrocarbons and unsaturated compounds, etc., to achieve the purpose of decomposing odor and purifying air. However, chlorine dioxide is stable and low, and is generally made into liquid or paste-shaped inert products. The effective release period of the activated chlorine dioxide is short, and transportation, storage and use are not convenient. The paste is the main direction of improvement at present. For example, the authorized announcement No. CN105145626B- is a kind of aromatic solid gel type chlorine dioxide air purification agent. The liquid phase component of the activator is the main component, which improves the stability of the product in storage and transportation compared with the commercial chlorine dioxide stable liquid phase. The activator of the liquid phase quickly merges into the solid phase containing chlorine dioxide, and the activation speed is fast. However, the packaging volume of the liquid phase activator is large, and there is a situation of spilling during use. At the same time, the purification effect lasts for 10-15 days, and the cycle is short.

[0003] The air purification tank is a new type of air purification product, which is different from the active purification purifier and the passive adsorption active carbon purification product. It does not need electricity and works all day after activation. The present application is a kind of double solid phase air purification product after long-term research and development. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide an air purification agent and a preparation method thereof, which has high stability and long purification cycle, and to provide a preparation method and use method thereof.

[0005] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0008] As preferred, the paste comprises by weight parts: cellulose thickening powder 10 parts, sodium alginate 5 parts, chitin 2 parts, chitosan 15 parts, zinc oxide 1 part, chlorate 2 parts and water 65 parts;

[0009] The activator comprises by weight parts: water condensing agent 20 parts, citric acid 50 parts, and flower fragrance 30 parts.

[0010] As preferred, the water condensing agent is a combination of carboxymethyl cellulose ether, polyacrylamide and water glass, and the mass ratio of the three is 10:1.5-2:0.1-0.5.

[0011] As preferred, the flower fragrance is natural dried flowers, and the dried flowers are selected from one of rose, lavender, jasmine, osmanthus and chrysanthemum, and the water content is less than 10%.

[0012] As preferred, the chlorate comprises at least one of potassium chlorate, sodium chlorate and magnesium chlorate.

[0013] As preferred, the paste and the activator are used in a ratio of 100:1-5.

[0014] A preparation method of an air purifier, comprising the following steps:

[0015] S1, preparing a paste: 1) dissolving cellulose thickening powder, sodium alginate, chitin and chitosan in water according to the ratio to form a slurry mixture, and continuously stirring with a stirrer at a speed of more than 500 rpm for 15 hours;

[0016] 2) adding zinc oxide and continuously stirring for two hours to make it uniformly dispersed to form a white slurry;

[0017] 3) changing the stirring speed and fully circulating the slurry through a circulating pump for 48 hours to prepare a paste slurry;

[0018] 4) adding chlorate according to the ratio;

[0019] 5) heating the slurry to 99 DEG C, filling the tank into a tank body, rapidly cooling and coagulating into a high-temperature-resistant paste;

[0020] 6) placing at room temperature for 10 hours, volatilizing excess water, completing the preparation of the purification tank, and packaging;

[0021] S2, preparing an activator: mixing water condensing agent, citric acid and flower fragrance according to the ratio and directly packaging.

[0022] A use method of an air purifier, characterized by comprising the following steps: uniformly sprinkling the activator on the surface of the paste, and about 1 hour later, the milky white paste gradually changes into lemon color, which is the activation effect.

[0023] Compared with the prior art, the air purifier has the following advantages:

[0024] The citric acid in the air purifying agent of the present application will react with chlorate to form chlorine dioxide, and the acidity of the citric acid will slowly destroy the paste structure, slowly release water molecules, accelerate the volatilization of the effective components by using the principle of water evaporation; at the same time, under the action of the condensation agent, water in the air and on the surface of the paste is absorbed to form a network film, the citric acid in the activator slowly reacts with the chlorate in the paste to gradually activate and slowly release chlorine dioxide gas molecules, which oxidize the toxic and harmful gases in the air to convert the harmful substances into harmless substances; the paste and the activator are both in solid phase, have high stability, are convenient for transportation and storage, and have a long purification period of 30-45 days after single activation, and a long continuous activation and use period of 1 year.
