▎ 摘　　要

NOVELTY - A graphene three-dimensional printing material, comprises 100 pts. wt. polyetheretherketone, 0.1-12 pts. wt. graphene, 0.1-3 pts. wt. lubricant, 0.1-2 pts. wt. coupling agent and 0.1-1 pt. wt. additive. The graphene is a graphene oxide microplate. The oxygen content of printing material is 30-35%. The number of layers is not more than 10. The microscopic size is 100-500 ~mm. USE - Graphene three-dimensional printing material for use in aerospace and weapon. ADVANTAGE - The graphene oxide microsheets with specific morphology are embedded in the polyether ether ketone resin in a corrugated shape and fully contact with the polymer chain segments, thus increasing the effective bonding area with the resin matrix, achieving a more ideal two-phase interface control, and improving the microstructure stability of the composite material. The material has excellent salt spray corrosion resistance. The graphene three-dimensional printing wire has the characteristics of excellent weather resistance, high mechanical strength, strong stability, and outstanding salt spray corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of graphene three-dimensional printing material, which involves (1) drying the raw-materials, taking in proportion, fully mixing the portion of graphene oxide microchips with a microscopic size of less than 100 ~mm with other materials through high-speed stirring, (2) melt-extruding the blended material obtained in step (1) through a twin-screw extruder to obtain a composite masterbatch, the heating temperature of each zone is 360-400?oC and drying the pellets at 120 degrees C for 6-10 hours for use and (3) fully mixing the composite masterbatch obtained in step (2) with all remaining graphene oxide microchips with a microscopic size greater than 100 ~mm, extruding and drawing by a high-temperature resin wire drawing machine, collecting into a coiled wire through a disc winding, the heating temperature of each zone of the wire drawing machine is 360-380 degrees C, drying the wire and vacuum packaging.
