The present invention relates to the technical field of color masterbatch preparation, in particular to a preparation method of high-performance antistatic color masterbatch. The method comprises: calcining silicon carbide whiskers in a vacuum environment, cooling the calcined silicon carbide whiskers, dispersing them in a solution for plasma treatment, and performing vacuum drying to obtain silane coupling agent-modified silicon carbide whiskers; adding raw materials into a mixer by weight parts for stirring, then transferring the mixture into a twin-screw extruder for melt blending treatment, and adaptively adjusting the melting temperature based on melting data at each sampling time during the melting of the mixed raw materials; extruding the melt-blended material, performing air-cooled pelletization, and vacuum drying to obtain the antistatic color masterbatch. The present invention avoids the disadvantage that excessively high or excessively low melting temperature of the twin-screw extruder during color masterbatch preparation affects the properties of the color masterbatch, and obtains a color masterbatch with sufficient melting, good antistatic properties and mechanical properties.
