This paper aims to explore the promoting effect of carbon fiber content on improving the mechanical properties of PP foamed material and the influence of azodicarbonamide and dibutyl phthalate content on the mechanical properties of packaging materials, so as to improve the mechanical properties of PP foamed packaging materials and expand its application areas. The carbon fiber modified polypropylene foam packaging material was prepared by the molding method, with polyacrylonitrile-based carbon fiber and PP powder as the main body, dibutyl phthalate as the plasticizer, calcium carbonate as the filler, and azodicarbonamide as the main body Foaming agent, and zinc oxide was used to lower the temperature. Polypropylene foam packaging material calcium carbonate was used as the filler, azodicarbonamide is the foaming agent, and it was molded under the conditions of a temperature of 180 ℃ and a vulcanization pressure of 7.5 MPa. The effects of different contents of different carbon fibers, azodicarbonamide and dibutyl phthalate on the mechanical properties of polypropylene foam packaging materials were determined. When PP is 80 g, the carbon fiber is 10 g, the zinc oxide is 4 g, the calcium carbonate is 20 g, the azodicarbonamide is 1.5 g, and when DBP is 7.5 g, the tensile strength is 31.34 MPa. It concludes that the use of carbon fiber modified PP as the main foam packaging material can improve its tensile properties. The test results meet the national standards and have a good application prospect in the field of packaging materials.
