▎ 摘　　要

NOVELTY - A conductive three-dimensional printing material comprises polypropylene, cobalt-nickel alloy powder, graphene, antioxidant, dispersant, gas phase silicon dioxide, and sterilizing mildew-proof agent. USE - Conductive three-dimensional printing material. ADVANTAGE - The good conductivity of graphene and cobalt-nickel are set so that the material can be adsorbed by magnetic substance and convenient for use in magnetic environment. The heat resistance of gas phase silicon dioxide reinforcing material is set to reduce the possibility of softening material after electrifying. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of conductive three-dimensional printing material comprising putting raw materials into drying box, drying for 24 hours to obtain ing dried powder, cooling at room temperature for at least 6 hours while keeping room closed without wind, repeatedly grinding filter particles until qualified, placing in mixing barrel, adding into ultrasonic dispersion machine, dispersing and mixing at 50-80degrees Celsius for at least one hour, placing mixed material in double-screw extruder, extruding and granulating at 200-300degrees Celsiusat screw rotating speed of 200-300 revoluions/minute, sealing and packing, and placing in warehouse. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of preparation of conductive three-dimensional printing material (Drawing includes non-English language text).
