Abstract

The invention provides a hypochlorous acid disinfectant and a preparation method thereof, and relates to the field of disinfectants. The hypochlorous acid disinfectant comprises the following components in percentages by weight: 5% to 8% of hypochlorous acid, 1% to 3% of sodium hypochlorite, 0.5% to 1% of polyhexamethylene guanidine, 0.1% to 0.5% of crustacean amine, 4% to 8% of polybasic modifiedwater-soluble chitosan, 1% to 5% of nanosilicon dioxide, 0.8% to 1.4% of sodium dihydrogen phosphate, 1% to 2% of inositol, 1% to 2% of ethylene diamine tetraacetic acid, 2% to 4% of polyoxyethyleneoctyl phenol ether, 1% to 2% of quaternized polyether amine, 1% to 2% of polyvinylpyrrolidone, 3% to 5% of lauric acid, 15% to 20% of ethanol, and the balance of deionized water. The hypochlorous aciddisinfectant prepared in the invention has preferable disinfection and sterilization effects and takes effect rapidly, and the sterilizing rate within 10 min reaches 100%.

Description

technical field [0001] The invention relates to the field of disinfectant, in particular to a hypochlorous acid disinfectant and a preparation method thereof. Background technique [0002] Disinfectants are used to kill pathogenic microorganisms on the transmission medium to make them harmless, eliminate pathogenic microorganisms outside the human body, cut off the transmission of infectious diseases, and achieve the purpose of controlling infectious diseases. High-efficiency disinfectants can kill all bacterial propagules (including mycobacteria), viruses, fungi and their spores, etc., and have a certain killing effect on bacterial spores to meet high-level disinfection requirements, including chlorine-containing disinfectants, ozone, methyl Hydantoin compounds, double-chain quaternary ammonium salts, etc. Intermediate-effect disinfectants can only kill microorganisms such as mycobacteria, fungi, viruses and bacterial propagules, and meet the disinfection requirements, inc...
