This invention pertains to the field of polymer technology and specifically discloses a high crystallinity functional masterbatch modified polypropylene and its preparation method. The preparation method comprises the following steps: S1 Masterbatch Preparation: Weigh the raw material components in the following parts by mass: 100 parts of polypropylene base material; 0.1-6.25 parts of antioxidant; 0.2-12.5 parts of auxiliary antioxidant; 0.2-12.5 parts of nucleating agent; 0.1-6.25 parts of lubricant; 0.3-18.75 parts of light stabilizer; 0.2-12.5 parts of antistatic agent; mix the above raw materials evenly, and extrude the evenly mixed powder through a twin-screw extruder to obtain high crystallinity polypropylene functional masterbatch; S2 High Crystallinity Polypropylene Preparation: Mix the prepared high crystallinity polypropylene masterbatch evenly with polypropylene powder or granules, extrude and granulate using a twin-screw extruder or directly produce parts using an injection molding machine to obtain high crystallinity polypropylene. The method described in this invention can reduce dust hazards, and the granular masterbatch feeding is smooth, preventing issues such as wall sticking and bridging caused by powdered additives during the feeding process, thereby improving product quality.
