The present invention provides a high-gloss toughened weather-resistant color masterbatch and a preparation method thereof, belonging to the technical field of plastics. The preparation method comprises the following steps: S1: mixing modified carbon black powder, PC resin, heat-resistant ABS resin and brightening agent uniformly in a high-speed mixer; S2: feeding the above mixture into a twin-screw extruder, and performing melting, extrusion, pelletization and drying to prepare the high-gloss toughened weather-resistant color masterbatch. The high-gloss toughened weather-resistant color masterbatch prepared by the present invention has good heat resistance, weather resistance and light aging resistance, and high glossiness. When added into PC resin, it can play an excellent toughening role, improve the thermal stability of PC resin, and has little impact on mechanical properties, thus having broad application prospects.
