Abstract

The invention discloses an environment-friendly sterilizing agent and a preparation method thereof. The environment-friendly sterilizing agent is prepared from the following components in parts by weight: 5-8 parts of polyhistidine, 3-5 parts of chitosan, 3-5 parts of cyclodextrin, 2-3 parts of epsilon-polylysine, 0.05-0.8 part of polypyrrole, 0.01-0.04 part of citric acid, 8-12 parts of polyethylene glycol and 65-72 parts of water. The invention also provides the preparation method of the environmental-friendly sterilizing agent. The preparation method comprises the following steps: (1) weighing 3-5 parts of chitosan, 3-5 parts of cyclodextrin, 2-3 parts of epsilon-polylysine, 0.05-0.8 part of polypyrrole and 8-12 parts of polyethylene glycol; and (2) adding the components into a reaction kettle, heating, adding 65-72 parts of water under the stirring condition, slowly adding 0.01-0.04 part of citric acid, adding 5-8 parts of polyhistidine under the sunshine-shading condition, stirring till all the components are dissolved, cooling, defoaming and thus obtaining the environment-friendly sterilizing agent.

Description

technical field [0001] The invention belongs to the field of sterilization materials, in particular to an environment-friendly sterilization agent and a preparation method thereof. Background technique [0002] The commonly used disinfection methods in the past were high temperature, ozone, ultraviolet radiation, chlorine gas disinfection or steam disinfection. The high temperature box steam disinfection method is to reach a certain high temperature by heating to kill harmful bacteria, and the sterilization temperature is high. The sterilization method of ozone and ultraviolet radiation is to sterilize through ozone, which requires a certain concentration of ozone to have a good bactericidal effect. The chlorine gas disinfection method is to disinfect through the strong oxidizing effect of chlorine gas. [0003] Chinese patent CN 104082293 A discloses a compound alcohol disinfectant and its preparation method, which includes 20-30% ethanol, 30-40% n-propanol, 0.2-2% surfact...
