High-stability molecular-state hypochlorous acid disinfectant and preparation method thereof

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...

[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. pollution, and some hypochlorous acid disinfectants without pungent odor are unstable. After a period of storage, the bactericidal and antibacterial effects are poor, the bactericidal effect is not obvious, the bactericidal and antibacterial effects are slow, and the expected effect cannot be achieved.
