Abstract

The invention relates to a preparation method of a modified polycarbonate fresh-keeping material. The method comprises the following steps: 1, putting a certain amount of polycarbonate, a reinforcing agent, a matting agent, an antibacterial agent, a lubricating agent and a composite antioxidant into a stirrer, conducting mixing and uniform stirring to obtain a mixture; and 2, carrying out melt extrusion granulation on the mixture obtained in the step 1 through a twin-screw extruder to obtain the modified polycarbonate fresh-keeping particles. The preparation method of the modified polycarbonate fresh-keeping material is simple and convenient, and the reinforcing agent, the matting agent, the antibacterial agent, the lubricant and the composite antioxidant are added into the polycarbonate, so that the obtained product is good in oxidation resistance and high in fresh-keeping capacity, and does not easily affect the body health of people.
