The present invention discloses a grafted hydrophobic modified polypropylene composite material and its preparation method, which comprises the following steps: Polypropylene, primary antioxidant, secondary antioxidant, lubricant, initiator, and silane coupling agent are uniformly mixed by weight ratio, fed into a twin-screw extruder for extrusion, cooled, dried, and pelletized to obtain polypropylene material A. Polypropylene, primary antioxidant, secondary antioxidant, slip agent, initiator, and fluorinating agent in a weight ratio, uniformly mix them, feed them into a twin-screw extruder for extrusion, cool, dry, and pelletize to obtain polypropylene material b; uniformly mix polypropylene material a with polypropylene material b, feed them into a twin-screw extruder for extrusion, cool, dry, and pelletize to obtain the grafted hydrophobic modified polypropylene composite material. The preparation method of the present invention enhances the hydrophobic properties of the material.
