NOVELTY - A preparation method of antibacterial polypropylene material comprises (S1) adding 30-45 %mass polypropylene resin, 30-50 %mass polyethylene resin, 5-10 %mass coupling agent, 8-15 %mass antibacterial agent, 3-5 %mass antioxidant, and 0.5-2 %mass UV absorbent to a mixer, and stirring at 300-500 rpm for 3-10 minutes, (S2) adding the stirred raw materials to a screw extruder, where the temperature of the screw extruder is set as 150-180℃ in zone 1, 190-200℃ in zone 2, 210-220℃ in zone 3,220-240℃ outlet temperature, and 350-400 rpm speed control, and (S3) injection molding. USE - The method is used for preparing antibacterial polypropylene material, which is used in medical antibacterial tool or medical clothing (claimed). ADVANTAGE - The prepared antibacterial polypropylene material has good mechanical properties, anti-UV aging ability and antibacterial effect.
