The invention discloses a corrosion-resistant and lightweight bicycle pedal material and a preparation method thereof. The material comprises the following components in parts by weight: 20–30 parts of low-molecular-weight polyphenylene ether resin, 25–35 parts of transparent polystyrene resin, 15–20 parts of toughener, 10–15 parts of hollow glass microspheres, 10–15 parts of glass fiber, 2–3 parts of polytetrafluoroethylene, 0–1 part of antioxidant, 0–1 part of light stabilizer, 1–2 parts of acid scavenger, and 0–1 part of other additives. The low-molecular-weight polyphenylene ether resin, transparent polystyrene resin, toughener, polytetrafluoroethylene, acid scavenger, antioxidant, light stabilizer and other additives are added into a high-speed mixer in proportion and mixed evenly, then fed from the main feeding port of a twin-screw extruder with double-sided feeding; glass fiber is added from the side feeding port in the third zone, and hollow glass microspheres are added from the side feeding port in the seventh zone, followed by extrusion, water cooling and pelletization. The material of the invention has improved toughness, chemical resistance, wear resistance and strength, effectively prolonging the service life of the product.
