▎ 摘　　要

NOVELTY - Graphene 3-dimensional (3D) printing material comprises 6-10 pts. wt. modified graphene, 30-60 pts. wt. polyetherimide, 18-24 pts. wt. silicate fiber, 12-20 pts. wt. epoxy resin, 3-15 pts. wt. nano titanium dioxide, 0.1-3 pts. wt. antioxidant and 10-20 pts. wt. additive. The additive comprises 6-10 pts. wt. silicon dioxide aerogel, 3-5 pts. wt. aluminum phosphate gel, 3-5 pts. wt. acidic aqueous solution of tetraethyl orthosilicate, 2-5 pts. wt. stabilizer, 2-4 pts. wt. toughening agent, 2-4 pts. wt. dispersant and 1-3 pts. wt. adhesive. USE - As graphene 3D printing material. ADVANTAGE - The 3D printing material has high strength, high tensile strength and temperature-bearing capability, can be quickly formed, and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene 3D printing material, which involves (i) drying modified graphene, polyetherimide, silicate fiber, epoxy resin, nano titanium dioxide and antioxidant, and uniformly mixing by manually, and (ii) crushing the mixture obtained in step (i) at (-80)-100 degrees C, adding additive, uniformly mixing, and adding the uniformly mixed mixture to a screw extrusion molding machine, and extruding at a rotational speed of 100-130 rpm and at 160-200 degrees C to obtain the product.
