Abstract

The invention discloses a preparation method of an organic disinfectant based on cyclodextrin modification. The method comprises the following steps: step one, preparation of modified cyclodextrin: sending cyclodextrin into a dispersion medium for modification treatment, wherein the modification rotating speed is 300-350r / min, the modification time is 20-30min, microwave assistance is adopted in the modification, the auxiliary power is 150-250W, and the auxiliary time is 15-25min. Cyclodextrin has inorganic-organic affinity, and when thecyclodextrin is dispersed in a dispersion medium, the dispersion effect of cyclodextrin is improved, and the distribution capacity of cyclodextrin in a disinfectant product is enhanced; the cyclodextrin can coat organic sterilization raw materials such as oxalic acid and the like in an inner cavity, and inorganic sterilization raw materials such as zinc chloride and the like are distributed outside the coating cavity of cyclodextrin, so that the organic materials and the inorganic materials are orderly connected, and the sterilization and disinfection effects of disinfection products are enhanced.

Description

technical field [0001] The invention relates to the technical field of organic disinfectants, in particular to a method for preparing an organic disinfectant based on cyclodextrin modification. Background technique [0002] Disinfectants are used to kill pathogenic microorganisms on the transmission medium to make them harmless, eliminate pathogenic microorganisms outside the human body, cut off the transmission of infectious diseases, and achieve the purpose of controlling infectious diseases; disinfectants are based on their level of action It can be divided into sterilizers, high-efficiency disinfectants, medium-efficiency disinfectants, and low-efficiency disinfectants. Sterilizers can kill all microorganisms to meet the sterilization requirements, including formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, chlorine dioxide, chlorine gas, copper sulfate, quicklime, ethanol, etc. [0003] Most of the existing disinfectants use inorganic dis...
