▎ 摘  要

NOVELTY - Thermoplastic resin comprises (wt.%): graphite (10-15), carbon black (5-10), surfactant (0.5-10), carrier resin (10-65) and auxiliary agent (2-10). USE - Thermoplastic resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing thermoplastic resin, which involves: (A) modifying graphene by treating surface with surface active agent to obtain surface positive charge of graphene, where positive charge dispersion time is 0.5-20 hours; (B) adding and dispersing surface active agent coated graphene into carbon black solution and then filtering and drying to obtain graphene-carbon black electrostatic self-assembling compound, where dispersing time is 0.5-20 hours; (C) formulating mixed solution by dissolving configuration macromolecule mixed solution and control the solvent of the mother carrier material in solvent; (D) mixing graphene-carbon black complex with mixed solution to obtain graphene-carbon black-polymer solution; (E) adding precipitator and initiator into graphene-carbon black-polymer solution to separate solid mixture from the solvent; (F) pressing and drying solid mixture to obtain dry master batch; and (G) adding auxiliary agent and thermoplastic material into master batch and then extruding and granulating thermoplastic material to obtain desired product.
