▎ 摘　　要

NOVELTY - Graphene three-dimensional printing material comprises 8-25 pts. wt. modified graphene, 3-15 pts. wt. nano titanium dioxide, 2-10 pts. wt. nano calcium carbonate, 35-39 pts. wt. polylactic acid, 18-23 pts. wt. acrylate, 2-10 pts. wt. crosslinking agent, 0.5-1 pts. wt. stabilizing agent and 0.5-1.2 pts. wt. toughening agent. USE - Used as graphene three-dimensional printing material. ADVANTAGE - The product has high impact, fast molding material. The material has high intensity, high tensile strength and is environmentally-friendly and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing material, comprising (i) drying the modified graphene, nano titanium dioxide, nano calcium carbonate, polylactic acid, acrylate, toughening agent and stabilizing agent and manually mixing uniformly, (ii) crushing the mixture obtained in the step (i) at the temperature is lower than -90-110 degrees C, adding crosslinking agent uniformly, placing the uniformly mixed mixture into a screw extrusion molding machine, where the temperature is 150-200 degrees C, the rotating speed is 100-120 revolutions/minute lower and extruding strip to obtain material.
