This invention discloses a purification masterbatch for odor removal, antibacterial, and preservation products, and its preparation method, belonging to the field of antibacterial and preservation technology. 25-50 parts of base resin, 0.05-0.2 parts of antioxidant, 0.2-1 part of lubricant, 0.05-0.25 parts of thickener, 0.02-0.05 parts of catalyst, and 0.05-0.25 parts of antibacterial agent are mixed and then melted and extruded through a twin-screw extruder, followed by granulation using a pelletizer to obtain a purifying masterbatch. The long-chain antibacterial agent enhances the antibacterial properties of the purifying masterbatch; the carbon nanotubes in the antibacterial agent enable the purifying masterbatch to remove odors; the chemical interaction between the unreacted carboxyl groups on the modified carbon nanotubes and the hydroxyl groups at the end of the resin firmly binds the antibacterial agent to the purifying masterbatch, preventing its loss and giving the purifying masterbatch stable antibacterial, preservation, and odor-removing effects.
