The present invention belongs to the technical field of polypropylene, and specifically relates to a high-strength, high-toughness, low-odor glass fiber reinforced polypropylene material and a preparation method thereof. The components comprise: 50–80 parts of polypropylene, 20–40 parts of glass fiber, 3–5 parts of compatibilizer, 0.2–0.5 parts of antioxidant, 0.1–0.4 parts of metal deactivator, 0.1–2 parts of deodorant, 0.5–1 part of colorant. Blending polypropylene, compatibilizer, antioxidant, deodorant, metal deactivator and colorant to obtain a premix; feeding the premix into a twin-screw extruder for melting; adding glass fiber or a compound of glass fiber and metal deactivator into the twin-screw extruder through side feeding, extruding, drawing, cooling and pelletizing to obtain the target product. The present invention modifies polypropylene, and the prepared composite material has high strength, high toughness and low odor.
