Embodiment 1

[0036] (1) Preparation of a two-component gel slow-release chlorine dioxide disinfectant:

[0037] Preparation of gel main ingredient: 11.0g gelatin, add 30.0g water, heat to 60°C and fully stir to dissolve to obtain gelatin aqueous solution; dissolve 1.2g sodium chlorite in 15.0g water, then add 0.2g sodium hydroxide and 0.2 g of sodium benzoate, stirred evenly to obtain a mixed aqueous solution of sodium chlorite; adding the mixed aqueous solution of sodium chlorite to the aqueous gelatin solution, stirred evenly, and after cooling, the gel main agent was obtained.

[0038] Solid activator: 2.5g sodium diacetate.

[0039] (2) Activation method:

[0040] The above-mentioned solid activator is added into the gel main agent, and chlorine dioxide gas can be released slowly and steadily.

[0041] The reaction equation is as follows:

[0042] 5NaClO 2 +4C 4 h 7 o 4 Na=4ClO 2 +4C 4 h 6 o 4 Na 2 +NaCl+2H 2 O (1)

[0043] (3) Application:

Abstract

The invention belongs to the technical field of disinfectants, and relates to a two-component gel slow-release chlorine dioxide disinfectant as well as a preparation method and application thereof. Comprising a gel main agent and a solid activator, the raw materials of the gel main agent comprise gelatin, chlorite, an alkaline compound, a preservative and water, and the solid activator is selected from one or more of sodium diacetate, citric acid, 2-acrylamide-2-methylpropanesulfonic acid and itaconic acid; the mass ratio of the gelatin to the chlorite to the alkaline compound to the preservative to the water to the solid activating agent is 11 to (0.5 to 3.0) to (0.1 to 0.8) to (0.1 to 0.8) to (25.0 to 75.0) to (0.6 to 5.0). When in use, the solid activating agent is added into the gel main agent, an activating reaction is carried out at room temperature, and chlorine dioxide gas is slowly released. The activated bi-component gel slow-release chlorine dioxide disinfectant is placed in a relatively closed place to disinfect ambient air.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, and in particular relates to a two-component gel slow-release chlorine dioxide disinfectant and a preparation method and application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Chlorine dioxide is a yellow-green to orange-yellow gas with high-efficiency and broad-spectrum sterilization and disinfection effects. It can be used in water treatment, pulp bleaching, food processing and disinfection, air disinfection and purification, and fruit and vegetable preservation. [0004] There are many preparation methods about chlorine dioxide disinfectant at present. For example, a sl...
