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
The invention belongs to sterile material field, particularly a kind of environmental protection bactericidal agent and preparation method thereof.
