Composite quaternary ammonium salt low-temperature disinfectant and preparation method thereof

Abstract

The invention relates to a composite quaternary ammonium salt low-temperature disinfectant and a preparation method thereof. The composite quaternary ammonium salt low-temperature disinfectant is prepared from the following raw material components: dodecyl dimethyl benzyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, didecyl dimethyl ammonium chloride, didecyl dimethyl ammonium bromide, low alcohol and deionized water. The compound quaternary ammonium salt low-temperature disinfectant can effectively kill harmful microorganisms such as escherichia coli and staphylococcus aureus at the low temperature of-22 DEG C, and the sterilization rate reaches 99.999% or above. The composite quaternary ammonium salt low-temperature disinfectant can be used for sterilizing low-temperature environments of-22 DEG C and above and outer package surfaces of articles, and sterilizing inner walls and outer surfaces of refrigerated transport vehicles, containers, refrigeration houses and the like. The composite quaternary ammonium salt low-temperature disinfectant has the advantages of favorable low-temperature stability, no toxicity, harmlessness, no irritation, no corrosion and noninflammability, easily available raw materials and simple preparation method, and is suitable for industrial production and application.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, and in particular relates to a composite quaternary ammonium salt low-temperature disinfectant and a preparation method thereof. Background technique [0002] Due to the cold chain environment causing new crown cases, epidemic prevention and control must not only prevent people, but also prevent objects, especially anti-cold chain products have become a new problem arising from the changes in the new crown epidemic. At present, the positive detection rate of new coronavirus nucleic acid in imported cold chain food has increased significantly, and more provinces have been affected. The products involved range from seafood to livestock and poultry meat products, and the scope of virus contamination of imported materials has expanded from cold chain food to containers. The disinfection of cold chain food has become an increasingly prominent issue in epidemic prevention and control. [0003] H...

AI Technical Summary

Problems solved by technology

The main reason is that the low temperature affects the disinfection effect of existing disinfectants and disinfection methods, resulting in a significant decline in the disinfection effect of disinfectants and some disinfection methods, and even makes common disinfection methods completely ineffective.

There is currently a worldwide shortage of low-temperature disinfectants
