Abstract

The invention particularly discloses a natural antibacterial and mildew-proof agent and a high-molecular active antibacterial and mildew-proof slow-release packaging film. The natural antibacterial and mildew-proof agent comprises mustard essential oil, allicin and a eucalyptus leaf extract. The preparation method of the high-molecular active antibacterial and mildew-proof slow-release packaging film comprises the following steps: (1) adsorbing the natural antibacterial and mildew-proof agent in carbon nanotubes to prepare carbon nanotube composite microcapsules; (2) preparing composite active antibacterial mildew-proof slow-release paper from the carbon nanotube composite microcapsule and paper pulp; and (3) preparing the high-molecular active bacteriostatic mildew-proof slow-release packaging film from the composite active bacteriostatic mildew-proof slow-release paper and a high-molecular film through a hot-pressing compounding method. The natural antibacterial and mildew-proof agent disclosed by the invention has excellent antibacterial and mildew-proof effects; in addition, the active antibacterial and mildew-proof slow-release packaging film is prepared from the natural antibacterial and mildew-proof agent by adopting the method disclosed by the invention, so that the natural antibacterial and mildew-proof agent can be continuously released, and a continuous antibacterial and mildew-proof effect is generated.

Description

technical field [0001] The invention relates to the technical field of a bacteriostatic and antifungal agent and a bacteriostatic packaging film, in particular to a natural antibacterial and antifungal agent and a polymer active antibacterial and antifungal slow-release packaging film. Background technique [0002] Mustard essential oil is the essential oil obtained by steam distillation of yellow mustard seeds, which has antibacterial effect. Allicin (Allicin) is an organosulfur compound extracted from the bulb (garlic head) of the Alliaceae Allium plant, and also exists in onions and other Alliaceae plants, the scientific name is diallyl thiosulfinate It has inhibitory effect on a variety of gram-positive cocci and gram-negative bacilli, molds, viruses, protozoa, pinworms, etc. In the preparation process of the antibacterial and antifungal packaging film, mustard essential oil and allicin are usually added to the packaging film material as antibacterial and antifungal age...
