NOVELTY - Electromagnetic protective plastic comprises plastic substrate, compatibilizer, carbon fiber, two dimensional titanium carbide nanosheet, graphene aerogel and coupling agent. USE - Used as electromagnetic protective plastic. ADVANTAGE - The plastic is wide, has excellent mechanical property, is prepared by simple process, and it is suitable for the manufacturing of electronic device shell and other functional plastic for preventing electromagnetic radiation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electromagnetic protection plastic comprising (1) mixing the components by adding the matrix plastic, carbon fiber, two-dimensional Ti3C2 nanosheet, graphene aerogel and coupling agent, adding in the internal mixer, blending for 30-60 minutes at 60-80 degrees C to obtain the blended material, (2) extruding and granulating by adding the mixed material obtained in the step (1) in a double-screw extruder, extruding and granulating, then naturally cooling to room temperature to obtain the composite material particles, the parameters of the twin-screw extrusion process during extrusion molding are preferably: the first area temperature of the double-screw extruder is 170-220 degrees C, the second area is the temperature of 180-230 degrees C, the third area temperature is 190-260 degrees C, the fourth area is the temperature of 200-260 degrees C, the machine head temperature is 200-270 degrees C, the residence time of the raw material in the extruder is 2-6 minutes, the pressure is 30-50 MPa, the rotating speed of the screw is 25-50 rotations/minutes, (3) injection molding by adding the composite material particles obtained in step (2) into a vacuum drying box, vacuum drying at the temperature 70-90 degrees C (preferably 75-85 degrees C, more preferably 80 degrees C) for 1-2 hours, using injection molding machine to dry the composite material particle material injection molding.
