The invention discloses a high polymeric iodine surface antibacterial plastic and a preparation method thereof. The surface antibacterial plastic is prepared by immobilization of a high polymeric iodine disinfectant to a plastic surface. The surface antibacterial plastic utilizes the material surface high polymeric iodine ion contact physical sterilization mechanism to realize the antibacterial and sterilizing purposes, and has the characteristics of safety, high efficiency, fast sterilization, no consumption and low cost, etc. The preparation method of the surface antibacterial plastic includes: adopting plastic as the substrate material, coupling filler in the plastic with an organosilicon quaternary ammonium salt, and then immobilizing high polymeric iodine ions to the substrate surface, thus obtaining the high polymeric iodine surface antibacterial plastic. The high polymeric iodine surface antibacterial plastic can be used as various packing materials for preservation and fresh-keeping of food, drugs, fe
