Abstract

The invention provides a composite quaternary ammonium salt disinfectant and a preparation method thereof. The composite quaternary ammonium salt disinfectant is prepared from the following raw materials: double-long-chain quaternary ammonium salt, two single-long-chain quaternary ammonium salts, synergist isothiazolinone, nonionic surfactant fatty alcohol polyvinyl ether and water. The double-long-chain quaternary ammonium salt is dialkyl dimethyl ammonium chloride, and dialkyl is two mutually independent alkyl groups with the carbon chain length of 8 to 18; the two single-long-chain quaternary ammonium salts are respectively alkyl dimethyl benzyl ammonium chloride with the carbon chain length of 8 to 18 and alkyl dimethyl ethyl benzyl ammonium chloride with the carbon chain length of 8 to 18. The components of the composite quaternary ammonium salt disinfectant have a synergistic effect, so that the anti-interference capabilities of hard water resistance and organic matter resistance are greatly improved; not only can bacterial propagules, lipophilic viruses (enveloped viruses such as novel coronaviruses) and fungi be killed, but also hydrophilic viruses (non-enveloped viruses) can be killed. In addition, the composite quaternary ammonium salt disinfectant provided by the embodiment of the invention is high in killing speed.

Description

technical field [0001] The invention relates to the field of disinfectants, in particular to a compound quaternary ammonium salt disinfectant and a preparation method thereof. Background technique [0002] In recent years, new and sudden enveloped viruses, such as influenza, SARS, Middle East respiratory syndrome, swine fever, Ebola, and new coronaviruses, have brought serious threats to human life and property. In the absence of specific drugs and vaccines, measures such as regular disinfection of public places and strengthening personal daily protection have proven to be one of the effective means to control the rapid spread of the new coronavirus. [0003] According to the list of disinfectants released by the EPA to deal with the new coronavirus, quaternary ammonium salt disinfectants account for a large proportion, which is an important disinfectant for fighting the epidemic. Quaternary ammonium salts are a class of cationic surfactants, and the general structural form...
