| description | The invention discloses a preparation process for a slow-release type chlorine dioxide microcapsule antibacterial film. The preparation process comprises the following operation steps: 1, preparing microcapsule powder: dissolving gelatin in a stable chlorine dioxide aqueous solution to obtain a water-phase solution; dissolving PLA in dichloromethane to obtain an oil-phase solution; and adding a Span-80 emulsifier into the oil-phase solution, then adding the water-phase solution and liquid paraffin, performing stirring, performing vacuum filtration, and performing lyophilization to obtain the chlorine dioxide microcapsule powder; and 2, preparing the antibacterial film: adding the chlorine dioxide microcapsule powder, an activator and a plasticizer to a film-forming base material PLA, performing uniform stirring, allowing the stirred materials to stand for 60min for eliminating bubbles, and performing coating by a flat-board coating machine to form the film. According to the invention, the antibacterial film p |
