The present invention relates to the technical field of composite materials, and discloses a preparation process of a polypropylene composite material. The polypropylene composite material is prepared by first mixing polypropylene, a cyclodextrin flame retardant, a lubricant, an antioxidant and a modified inorganic filler, and then placing in a twin-screw extruder for melt extrusion and granulation. The cyclodextrin flame retardant is prepared by introducing flame-retardant elements nitrogen and phosphorus into the structure of β-cyclodextrin, and the modified inorganic filler is prepared by antibacterial modification of talc. Adding the cyclodextrin flame retardant and the modified inorganic filler into the preparation process of the polypropylene composite material effectively improves the comprehensive properties such as wear resistance and antibacterial properties of the composite material, and greatly broadens the application field of polypropylene materials.
