Embodiment 1

[0057] In this example, the attapulgite-based air-purifying slow-release gel was prepared by the following method:

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

[0059] Configuration 10% sodium chlorite solution, phosphate buffer is made solvent (promptly configuring 100 gram ph6.8 phosphate buffers is solvent, and sodium chlorite is the solution of solute, gets 10 gram sodium chlorite solids and 90 gram ph6. 8 phosphate buffer solution, the two can be mixed with each other); adding 2 grams of sodium carbonate solution with a concentration of 0.05mol / L, and then adding 16 grams of modified attapulgite with a mass fraction of 25%, stirring for subsequent use.

[0060] (2) Preparation of gel

[0061] Add 1 gram of carrageenan and 3 grams of gelatin in a beaker, weigh 1 gram of PVA1799 and add it; then add 1 gram of 4% PEG1500 (the PEG used in the following examples is the PEG) solution; Add 100 grams of water; boil the glue at a temperature...

Embodiment 2

[0066] In this example, the attapulgite-based air-purifying slow-release gel was prepared by the following method:

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

[0068] Prepare 20% sodium chlorite solution and phosphate buffer as solvent; add 2 grams of sodium carbonate solution with a concentration of 0.05 mol / L, and then add 16 grams of modified attapulgite with a mass fraction of 25%, stir and set aside.

[0069] (2) Preparation of gel

[0070] Add 1 gram of carrageenan and 3 grams of agar in a beaker, weigh 1 gram of PVA1788 and add it; add 1 gram of 4% PEG solution; add 100 grams of water after the addition; boil the gelatin at 95-100°C operate. The time to complete the dissolution is 4 hours; after that, adjust the temperature to 60°C to keep the glue warm for later use.

[0071] (3) Add 20 grams of fungicide and 5 grams of activator successively to the above-mentioned 80 grams of glue. The attapulgite-based air-purifying slow-rel...

Embodiment 3

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

[0074] Prepare 20% sodium chlorite solution and phosphate buffer as solvent; add 2 grams of sodium carbonate solution with a concentration of 0.05 mol / L, and then add 16 grams of modified attapulgite with a mass fraction of 25%, stir and set aside.

[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 the addition; perform the gelatinization operation at 95-100°C . The time to complete the dissolution is 4 hours; after that, adjust the temperature to 60°C to keep the glue warm for later use.

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

Abstract

The invention provides attapulgite-based air purification sustained-release gel as well as a preparation method and application thereof. The air purification sustained-release gel comprises a ClO2 reaction source, a carrier for bearing the ClO2 reaction source and a gel source for bearing the carrier. The attapulgite-based air purification sustained-release gel has the effect of slowly generatingClO2, can well control the sustained-release effect, has the effects of continuously removing aldehyde, sterilizing and purifying air, 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 its preparation method and application. Background technique [0002] According to statistics, people spend most of their time indoors (including in cars), and the indoor air quality has a very important impact on people's health. The air that people breathe indoors (including in cars) often contains volatile organic compounds such as formaldehyde and various bacteria. These volatile organic compounds and bacteria are threatening people's health all the time. How to effectively remove volatile organic compounds such as formaldehyde and various bacteria in the air has always been a hot topic of research. [0003] A large number of experimental studies have shown that chlorine dioxide is a safe and non-toxic disinfectant, without the "three causes" effects (carcinogenic, teratogenic, mutagenic), a...
