The invention relates to the technical field of polymer conductive materials, and provides a preparation method of an antistatic plastic master batch and an antistatic chemical fiber.The preparation method of the antistatic plastic master batch comprises the steps that materials including first resin and second resin are mixed to obtain a first mixed material, performing primary melt extrusion treatment on the first mixed material to obtain a first master batch; the first master batch is soaked in a solvent, so that the second resin in the first master batch is dissolved in the solvent, and a second master batch is obtained; and mixing the second master batch with carbon nanotubes to obtain a second mixed material, and carrying out second melt extrusion treatment on the second mixed material to obtain the antistatic plastic master batch. According to the preparation method of the antistatic plastic master batch provided by the invention, the dispersity of the carbon nanotubes in the antistatic plastic master
