Sliver-carried nano-montmorillonite antibacterial agent and preparation method thereof

The invention relates to a sliver-carried nano-montmorillonite antibacterial agent and a preparation method thereof. The antibacterial agent takes the nano lamellar montmorillonite as a carrier and comprises 6-9% antibacterial metallic element. The preparation method of the sliver-carried nano-montmorillonite antibacterial agent comprises the steps of: adding organic compound into montmorillonite suspending liquid to organically intercalate, and dropwise adding the organically-processed montmorillonite into silver nitrate ammonia water solution for the ion exchange reaction to prepare the nano-montmorillonite antibacterial agent. The antibacterial agent is high in efficiency, wide in antibiotic property, and good in compatibility with the polymer, thereby being applicable to the plastics, the fiber, and the like.
