▎ 摘　　要

NOVELTY - Modified acrylonitrile butadiene styrene material is claimed. The material is obtained by mixing dried styrene-butadiene-styrene and acrylonitrile butadiene styrene with surfactant, then adding glass fiber, alumina nanoparticles and graphene nanosheets, mixing after heating, performing screw extrusion, drying to obtain modified acrylonitrile butadiene styrene material. USE - The material is useful in three-dimensional printing of graphene nanosheets and alumina nanoparticles (claimed). ADVANTAGE - The material has improved cracking and cold shrinkage performance.
