The invention relates to the technical field of pipe production, in particular to a method for preparing a carbon fiber reinforced polypropylene cable protection pipe, comprising the following steps: Step 1: put carbon fiber into a hydrogen peroxide solution, carry out oxidation treatment, and combine the oxidized carbon fiber with a cage Type polysilsesquioxane, peroxide cross-linking agent and solvent are mixed to obtain thermal conductivity assistant; Step 2: combine the thermal conductivity assistant prepared in step 1 with 80-90 parts of polymerization degree of polypropylene, methacrylic acid, Toughening agent, glycidyl acrylate and filler are blended, extruded and granulated in a twin-screw extruder; Step 3: The granules obtained in Step 2 are blended with polypropylene with a degree of polymerization of 3000-3500, and then mixed with the pipe material. In the extruder, the cable protection tube with excellent thermal conductivity and insulation is obtained by extruding through the tube extruder. |
