Problems solved by technology

[0002] Hypochlorous acid disinfectant is welcomed by the market because it will not make bacteria and viruses resistant to drugs. Although the hypochlorous acid disinfectant on the existing market has a certain bactericidal ability, due to the excessive amount of hydrogen ions, the aqueous solution When it becomes strongly acidic, a large amount of chlorine gas will be produced, the content of available chlorine is low, the pH value of the solution is low, it has a str

preparation example Construction

[0022] A preparation method of a highly stable molecular hypochlorous acid disinfectant, comprising the following steps,

[0023] Step (1): preparing purified water;

[0024] Step (2): preparing the hydrochloric acid solution, adding food-grade hydrochloric acid into the purified water, stirring evenly at a low speed, to obtain a hydrochloric acid solution with a mass percentage concentration of 8%;

[0025] Step (3): preparing sodium hypochlorite solution, adding food-grade sodium hypochlorite to purified water, stirring evenly at a low speed, to obtain a sodium hypochlorite solution with a mass percentage concentration of 10%;

[0026] Step (4): preparation of hypochlorous acid water, mixing the hydrochloric acid solution in step (2) with the sodium hypochlorite solution in step (3), stirring evenly at a low speed, to obtain hypochlorous acid water;

[0027] Step (5): After passing the inspection of the hypochlorous acid water in step (4), seal it and store it in a storage ...

Embodiment 1

[0032] A highly stable molecular hypochlorous acid disinfectant comprises 99.8% purified water, 0.008% food-grade hydrochloric acid, 0.01% food-grade sodium hypochlorite and 0.182% sodium dihydrogen phosphate according to mass percentage. The amount of hydrogen ions in the hypochlorous acid disinfectant prepared by the preparation method forms highly stable molecular hypochlorous acid, produces relatively little chlorine gas, and has a high content of available chlorine. The pH value of the hypochlorous acid disinfectant is 6.8, no It has a pungent smell, will not damage the skin, and has a good bactericidal and antibacterial effect. After a period of storage, the bactericidal and antibacterial effect is normal and achieves the expected effect.

Embodiment 2

[0034] A highly stable molecular hypochlorous acid disinfectant comprises 99.78% purified water, 0.0075% food-grade hydrochloric acid, 0.011% food-grade sodium hypochlorite and 0.2015% sodium dihydrogen phosphate according to mass percentage. The hypochlorous acid disinfectant prepared by the preparation method has an appropriate amount of hydrogen ions to form highly stable molecular hypochlorous acid, which produces very little chlorine gas and high content of available chlorine. The pH value of the hypochlorous acid disinfectant is 6.4, without stimulation Non-toxic odor, will not damage the skin, good bactericidal and antibacterial effect, after a period of storage, the bactericidal and antibacterial effect is normal, and the expected effect is achieved.

Abstract

The invention discloses a high-stability molecular-state hypochlorous acid disinfectant and a preparation method thereof, The method comprises: (1) a step of preparing purified water; (2) a step of blending a hydrochloric acid solution; (3) a step of blending a sodium hypochlorite solution; (4) a step of preparing an aqueous hypochlorous acid solution, namely a step of mixing the hydrochloric acidsolution in the step (2) with the sodium hypochlorite solution in the step (3), and uniformly stirring at a low speed to obtain the aqueous hypochlorous acid solution; (5) a step of, after the aqueous hypochlorous acid solution in the step (4) is inspected to be qualified, hermetically storing the aqueous hypochlorous acid solution in a storage tank, and shading for storage; and (6) a step of preparing a hypochlorous acid disinfectant, namely a step of adding sodium dihydrogen phosphate into the aqueous hypochlorous acid solution in the step (5) to prepare the hypochlorous acid disinfectant.The disinfectant has a proper amount of hydrogen ions, and forms high-stability molecular hypochlorous acid, and is high in the content of available chlorine, free of pungent smell, free of damage toskin, good in sterilization and bacteriostasis effects and long in storage time.

Description

technical field [0001] The invention relates to the technical field of disinfectant, in particular to a highly stable molecular hypochlorous acid disinfectant and a preparation method thereof. Background technique [0002] Hypochlorous acid disinfectant is welcomed by the market because it will not make bacteria and viruses resistant to drugs. Although the hypochlorous acid disinfectant on the existing market has a certain bactericidal ability, due to the excessive amount of hydrogen ions, the aqueous solution When it becomes strongly acidic, a large amount of chlorine gas will be produced, the content of available chlorine is low, the pH value of the solution is low, it has a strong pungent smell, and it is easy to damage the skin. Long-term use will affect people's physical and mental health, and it also has a certain impact on the environment. However, some non-irritating hypochlorous acid disinfectants are unstable. After a period of storage, the bactericidal and antibac...
