Embodiment 1

[0057] In the present embodiment, attapulgite-based air-purifying slow-release gel is prepared by the following method:

[0058] (1) preparation process of attapulgite-loaded sodium chlorite fungicide:

[0059] Configure 10% sodium chlorite solution, phosphate buffer as solvent (that is, configure 100 grams of ph6.8 phosphate buffer as solvent, sodium chlorite as solute solution, take 10 grams of sodium chlorite solid and 90 grams of ph6. 8 Phosphate buffer solution, mix the two with each other); add 2 grams of sodium carbonate solution with a concentration of 0.05mol / L, and then add 16 grams of modified attapulgite with a 25% mass fraction, and stir for later use.

[0060] (2) Preparation of gel

[0061] Add 1 gram of carrageenan and 3 grams of gelatin to the beaker, weigh 1 gram of PVA1799 and add it; then add 1 gram of 4% PEG1500 (the PEG used in the following examples is this PEG) solution; Add 100 grams of water; carry out the glue boiling operation at 95°C oil bath tem...

Embodiment 2

[0066] In the present embodiment, attapulgite-based air-purifying slow-release gel is prepared by the following method:

[0067] (1) preparation process of attapulgite-loaded sodium chlorite fungicide:

[0068] 20% sodium chlorite solution was prepared, and phosphate buffer was used as solvent; 2 grams of sodium carbonate solution with a concentration of 0.05mol / L was added, and 16 grams of modified attapulgite with 25% mass fraction was added, and it was stirred for later use.

[0069] (2) Preparation of gel

[0070] Add 1 gram of carrageenan and 3 grams of agar to the beaker, weigh 1 gram of PVA1788 and add it; then add 1 gram of 4% PEG solution; after adding, add 100 grams of water; boil the gel at 95-100 °C operate. The dissolution completion time was 4 hours; after that, the temperature was adjusted to 60°C, and the glue was kept warm for later use.

[0071] (3) 20 grams of bactericide and 5 grams of activator were successively added to the above-mentioned 80 grams of ...

Embodiment 3

[0073] (1) preparation process of attapulgite-loaded sodium chlorite fungicide:

[0074] 20% sodium chlorite solution was prepared, and phosphate buffer was used as solvent; 2 grams of sodium carbonate solution with a concentration of 0.05mol / L was added, and 16 grams of modified attapulgite with 25% mass fraction was added, and it was stirred for later use.

[0075] (2) Preparation of gel

[0076] Add 1 gram of gelatin and 3 grams of agar into the beaker, weigh 1 gram of PVA1788 and add it; then add 1 gram of 4% PEG solution; add 100 grams of water after adding; boil the gel at 95-100 °C . The dissolution completion time was 4 hours; after that, the temperature was adjusted to 60°C, and the glue was kept warm for later use.

[0077] (3) 15 grams of bactericide and 5 grams of activator were successively added to the above-mentioned 80 grams of glue solution. The attapulgite-based air-purifying slow-release gel can be obtained by condensing in a can at 30°C.

Abstract

The invention provides an attapulgite-based air-purifying slow-release gel and a preparation method and application thereof. The air-purifying slow-release gel includes ClO 2 Reaction source, carrying the ClO 2 The carrier of the reaction source and the gel source supporting the carrier. The attapulgite-based air-purifying slow-release gel of the present invention has the ability to slowly generate ClO 2 It can well control its slow-release effect, has continuous aldehyde removal, sterilization, and air purification effects, and is safe and non-toxic.

Description

technical field [0001] The invention belongs to the technical field of air purification materials, and relates to an attapulgite-based air purification slow-release gel material and a preparation method and application thereof. Background technique [0002] According to statistics, people spend most of their time indoors (including in cars), and indoor air quality has a very important impact on people's health. The air people breathe indoors (including cars) often contains volatile organic compounds such as formaldehyde and various bacteria, which threaten people's health all the time. How to effectively remove formaldehyde and other volatile organic compounds and various bacteria in the air has always been a research hotspot. [0003] A large number of experimental studies have shown that chlorine dioxide is a safe and non-toxic disinfectant, and has no "three causes" effects (carcinogenic, teratogenic, and mutagenic), and at the same time, it does not undergo chlorination...
