Embodiment 1

[0018] Stir and mix 5 parts of graphene and 10 parts of alkylphenol polyoxyethylene ether evenly for later use; then add it to 75 parts of an aqueous solution containing 25% sodium chlorite and stir at high speed so that sodium chlorite enters the pores of graphene middle. Then add 20 parts of 20% aqueous solution containing sodium bisulfate to the above solution, and stir at room temperature for 2 hours, so that the chlorine dioxide mother liquor is fully reacted and intensified to generate chlorine dioxide molecules, which are fully adsorbed in the graphene pores. Then add one part per thousand of micro-nano silver and fully stir and disperse to form a chlorine dioxide slow-release solution.

Embodiment 2

[0020] Stir and mix 6 parts of molecular sieves and 15 parts of an aqueous solution containing 40% tetrabutylammonium bromide evenly and set aside; in the molecular sieve pores. Then add 25 parts of citric acid-containing 20% ​​aqueous solution to the above solution, and stir at room temperature for 2 hours, so that the chlorine dioxide mother liquor is fully reacted and intensified to generate chlorine dioxide molecules, which are fully adsorbed in the molecular sieve pores. Then add 1 / 1000 part of micronano zinc and fully stir and disperse to form a chlorine dioxide slow-release solution.

Embodiment 3

[0022] 7 parts of activated carbon and 15 parts of sodium dodecylbenzenesulfonate aqueous solution containing 20% ​​were stirred and mixed uniformly for later use; Barium chlorite enters the activated carbon pores. Then add 20 parts of 15% aqueous solution containing sodium dihydrogen phosphate to the above solution, and stir at room temperature for 2 hours, so that the chlorine dioxide mother liquor is fully reacted and intensified to generate chlorine dioxide molecules, which are fully adsorbed in the pores of the activated carbon. Then add 0.5 parts per thousand of micro-nano silver to fully stir and disperse to form a chlorine dioxide slow-release solution.

Abstract

The invention discloses a chlorine dioxide slow-release liquid and a preparation method thereof. The preparation method comprises the following steps: firstly, uniformly mixing a porous material and a surfactant, then uniformly dispersing the mixture in a chlorine dioxide mother solution, uniformly conducting mixing, then adding a slow-release exciting agent, finally adding micro-nano silver or micro-nano zinc, and uniformly conducting mixing. Chlorine dioxide is not purely dissolved in water, a part of chlorine dioxide is dissolved in water, the other part of chlorine dioxide is adsorbed in pores of the porous material, so that chlorine dioxide in the chlorine dioxide slow-release solution is far greater than the solubility of chlorine dioxide in water (the solubility is 0.8%), the porous material can increase the content of chlorine dioxide in the slow-release solution, and in the release process, the chlorine dioxide is firstly released into water from the porous material. The water solution is released outwards when reaching the solution degree, so that compared with existing solid-loaded chlorine dioxide or liquid chlorine dioxide, the release path is prolonged, and the slow release effect is further enhanced.

Description

technical field [0001] The invention belongs to the technical field of microcapsule preparation, and in particular relates to a chlorine dioxide slow-release liquid and a preparation method thereof. Background technique [0002] Chlorine dioxide is an efficient, safe and broad-spectrum disinfectant, which is widely used in various water treatment, air purification and disinfection, and food preservation. Automatically, slowly and continuously release low-concentration chlorine dioxide gas in the room, effectively kill germs and bacteria in the air, remove peculiar smell in the air, prevent indoor items from mildew in humid air, and sterilize and disinfect the air It has dual effects, improving the agricultural soil. At the same time, the atomic oxygen it decomposes can also freshen the air, and it will not cause harm or side effects to the human body. It can be widely used in air freshening and purification, soil improvement, sterilization and disinfection , anti-mildew, de...
