▎ 摘　　要

NOVELTY - Modified polysulfone (PSU) plastic comprises 0.5-21 pts. wt. modified white graphene, 0.5-12 pts. wt. white oil, 60-100 pts. wt. PSU resin and 0.5-20 pts. wt. dispersing agent, where the modified white graphene is polymer coated modified white graphene and polymerizable monomer of polymer is a styrene or acrylic ester monomer. USE - Used as PSU plastic. ADVANTAGE - The plastic improves the compatibility between white graphene and PSU matrix in presence of polymer coating of white graphene, and achieves uniform dispersion of white graphene in the PSU matrix; and has enhanced toughness and impact resistance and improved heat aging resistance and wear resistance due to a network structure formed by interlinking of white graphene with the PSU matrix. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing plastic, comprising mixing modified white graphene, white oil, polysulfone resin and dispersing agent to obtain a mixed material, and extruding and granulating the mixed material.
