The invention relates to a preparation method of polypropylene-loaded Schiff alkali metal complex antibacterial microspheres. The method comprises the following steps: (1) Weigh each monomer by mass percentage: 20% to 45% of acrylate hydrophobic comonomer %, acrylate hydrophilic cationic monomer quaternary ammonium salt 10%~35%, vinyl biocompatible monomer 10%~30%, acrylate coupling monomer 10~15%; The monomer and Schiff's alkali metal complex are sequentially added with deionized water and an initiator under stirring conditions, and a mixed solution is obtained after the reaction; (3) the mixed solution is polymerized in a heating bath, cooled to room temperature, and filtered to obtain polypropylene loaded with hydrogen. Alkali metal complex antibacterial microsphere emulsion; (4) Polypropylene supported Schiff alkali metal complex antibacterial microsphere emulsion is centrifuged, washed and dried to obtain powdery polypropylene supported Schiff alkali metal complex antibacterial microspheres. The process of the invention is simple, fast and easy to industrialize. |
