NOVELTY - Mobile phone protective shell of auxiliary heat dissipation comprises 45-63 wt.% thermoplastic polyurethane, 2-25 wt.% graphene, 15-20 wt.% ceramic powder, and 7-13 wt.% silicon oxide. USE - Used as mobile phone protective shell of auxiliary heat dissipation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: The manufacturing process of the mobile phone protective shell for auxiliary heat dissipation comprising (i) crushing the prepared thermoplastic polyurethane raw material, (ii) adding the crushed thermoplastic polyurethane raw material into a stirring device, and adding silicon oxide, graphene and ceramic powder into a stirring device for sufficient stirring and mixing, (iii) adding the mixed raw materials into an injection molding machine for heating and melting, and performing injection molding, (iv) cooling and shape the injection-molded mobile phone protective shell; and (v) deburring the cooled and shaped mobile phone protective case to ensure that it is smooth and burrs. The stirring device used in the manufacturing process of the mobile phone protective shell for auxiliary heat dissipation comprising the lower end of a stirring barrel (1) is fixedly provided with a discharging pipe, and the upper end is fixedly provided with a fixing mounting frame (12), and a stirring motor (2) is fixedly mounted on the middle position of the upper end of the fixed mounting frame. A main stirring shaft (21) is installed on the stirring motor, and the main stirring shaft passes through the fixed mounting frame and is plugged into the stirring barrel. DESCRIPTION OF DRAWING(S) - The drawing shows the assembling schematic diagram of the stirring device. 1Stirring barrel 2Stirring motor 12Fixing mounting frame 21Main stirring shaft
