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.
