Problems solved by technology

However, the inventors of the present invention have found that the bactericidal effect of the quaternary ammonium salt bactericide with a single bactericidal component will be limited in some use environments, and long-term use alone will produce drug resistance, and will also produce bactericidal effects on the surface of metal products after disinfection. Different degrees of corrosion, therefore, in order to improve the sterilization and disinfection effect and protect the metal products to be sterilized, it is necessary to compound the existing quaternary ammonium salt disinfectant to exert the synergy between the components, thereby expanding the scope of use of the quaternary ammonium salt disinfectant

Description

technical field [0001] The invention relates to the technical field of disinfectant products, in particular to a composite quaternary ammonium salt disinfectant and its preparation method and use method. Background technique [0002] Quaternary ammonium salt disinfectants have the characteristics of low concentration, low side effects, colorless, low irritation, and safety, and are therefore widely used as sterilizing and disinfecting agents in medical, surgical supplies, household personal, public health and other fields. However, the inventors of the present invention have found that the bactericidal effect of the quaternary ammonium salt bactericide with a single bactericidal component will be limited in some use environments, and long-term use alone will produce drug resistance, and will also produce bactericidal effects on the surface of metal products after disinfection. Different degrees of corrosion, therefore, in order to improve the sterilization and disinfection e...
