Preparation equipment and method of graphene polymer nano composite material

The preparation equipment comprises a stirring barrel, a stirring device is arranged in the stirring barrel, limiting frames are arranged on the two sides of the stirring barrel, the stirring barrel can slide up and down along the two limiting frames and is fixed, a top cover is arranged on the upper portion of the inner wall of the stirring barrel in a sliding mode, and the top cover is arranged on the lower portion of the inner wall of the stirring barrel in a sliding mode. The invention relates to the technical field of graphene material processing. According to the preparation equipment and method of the graphene polymer nano composite material, the graphene polymer nano composite material is stirred and mixed under the action of the stirring device, and raw materials in the stirring barrel can be moved and stirred up and down by utilizing the reciprocating lifting device; the low-efficiency mode that raw materials can only be mixed at the same position in the stirring process is avoided, and the process
