Embodiment Construction

[0020] Refer to figure 1 Shown: Provide a new compound quaternary ammonium salt disinfectant, which is made by mixing the following components in proportions; among them, 50 parts of dialkyl ((8-10) dimethyl ammonium chloride; dodecyl) 25 parts of dimethylbenzylammonium chloride; 2 parts of glutaraldehyde; 4 parts of dialkyl((8-10) dimethyl tertiary amine.

[0021] The method for preparing the above-mentioned new compound quaternary ammonium salt disinfectant adopts the following steps: putting the above-mentioned well-proportioned raw material components into a mixing container, adding a certain amount of deionized water, mixing it evenly with a machine, and packaging and leaving the factory.

[0022] The aldehydes, non-ionic surfactants, etc. in the present invention have a synergistic effect on sterilization and disinfection. The compound quaternary ammonium salt disinfectant has a synergistic effect on Staphylococcus aureus, Escherichia coli, Candida albicans, and Newcastle di...

Abstract

The invention discloses a novel compound quaternary ammonium disinfectant that can be prepared by mixing the component materials as below in proportion by share: 68-72 shares of dialkyl(C8-10) dimethyl ammonium chloride, 20-30 shares of dodecyl benzyl dimethyl ammonium chloride, 1-3 shares of glutaraldehyde and 2-6 shares of dialkyl(C8-10) dimethyl amine. The disinfectant can meet the requirement for disinfectant with high efficiency. The killing rate of the spores of bacillus subtilis var.niger and bacillus anthracis in 3-5 minutes is higher than 99% at 40ppm, and the disinfectant has preferable destructive effect on HBsAg at 50ppm. The killing rate of E.coli and Staphyloccocus aureus Rosenbach is higher than 99% at 30ppm. The killing rate of fowl plague virus is higher than 99% at 50ppm. The disinfectant can block the spread of H5N1 and H9N2 avian influenza virus as well as Newcastle disease virus among the chicken embryos effectively.

Description

Technical field [0001] The invention relates to a quaternary ammonium salt disinfectant, in particular to a novel compound quaternary ammonium salt disinfectant and a preparation method. To study the compatibility of compound quaternary ammonium salt with various synergists (aromatic aldehydes, non-ionic surfactants) and the mechanism of synergistic sterilization and disinfection; various factors (temperature, concentration) and their effects on sterilization and disinfection, and screen the best ratio The new compound quaternary ammonium salt disinfectant has a high killing effect on Staphylococcus aureus, coliform, Bacillus, Newcastle disease and avian influenza. , Background technique [0002] The double-stranded quaternary ammonium salt compound has been recognized as one of the most effective disinfectants and disinfectants for killing bacteria and viruses. On the one hand, the quaternary ammonium salt in the form of cations in the aqueous solution is harmful to all bacteria...
