Abstract

The invention discloses a compound quaternary ammonium salt low-temperature disinfectant which comprises a quaternary ammonium salt mixture, an anti-freezing agent and water, and the quaternary ammonium salt mixture is a mixture of single-chain quaternary ammonium salt, double-chain quaternary ammonium salt and heterocyclic quaternary ammonium salt. The heterocyclic quaternary ammonium salt, the single-chain quaternary ammonium salt and the double-chain quaternary ammonium salt are compounded and cooperated so that the sterilization effect can be greatly improved. The bactericide is a quaternary ammonium salt compound, has no corrosivity and no pungent smell, does not cause negative effects on operators and the environment, and can be used for disinfection in the environment of -40 DEG C or above. The invention further provides a preparation method of the compound quaternary ammonium salt low-temperature disinfectant.

Description

technical field [0001] The invention relates to the technical field of chemical disinfectants, in particular to a compound quaternary ammonium salt low-temperature disinfectant and a preparation method thereof. Background technique [0002] For a long time, in the field of disinfection, most researches have mainly focused on the disinfection effect of disinfectants under normal temperature or high temperature conditions, and little attention has been paid to the disinfection under low temperature environment, and there are very few corresponding low temperature disinfection products. [0003] Patent CN112450220A discloses a disinfection material used in a low-temperature environment and a preparation method thereof. The disinfection material used is a chlorine-containing chemical substance, and the solvent used is ether, acetone, DMF, carbon tetrachloride, etc. It is well known that chlorine-containing disinfectants are highly corrosive and have a strong odor during use, whi...
