▎ 摘　　要

NOVELTY - Three dimensional printing material based on graphene oxide comprises 37-60 wt.% ,graphene oxide aqueous solution, 25-45 wt.% petroleum resin, 1-5 wt.% antioxidant, 3-15 wt.% silica, and 2-7 wt.% active agent. USE - Used as three dimensional printing material based on graphene oxide. ADVANTAGE - The material: is simple economical and easy to control; has excellent printing effect, mild process, strong operability, and social application; improves crystallization rate and molding processability and reduces molding temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing three dimensional printing material based on graphene oxide comprising (i) adding ammonia to graphene oxide, stirring the reaction treatment with stirring mechanism, and mixing polyethylene glycol diglycidyl ether, stirring the reaction treatment again to obtain aqueous graphene oxide solution, (ii) mixing petroleum resin, antioxidant, silica and active agent carrying out melting treatment to obtain mixed material, (iii) adding the mixed material to the graphene oxide aqueous solution, stirring, extruding and pelletizing.
