▎ 摘　　要

NOVELTY - A graphene oxide modified polyethylene terephthalate material is prepared by taking refined terephthalic acid solution, dibasic acid, ethanediol, dihydric alcohol and graphene oxide and ethanediol solution, modulating into slurry, transporting into esterification reaction kettle for first esterifying under nitrogen atmosphere, adding catalyst, placing into pre-polycondensation reaction kettle, sending into final polycondensation tank for condensation polymerization, increasing viscosity increase, final polycondensing, pumping into sprinkle strip board, extruding, and cold water quenching. USE - Method for preparing graphene oxide modified polyethylene terephthalate material (claimed). ADVANTAGE - The material improves intrinsic viscosity, breaking strength and elongation break. DETAILED DESCRIPTION - A graphene oxide modified polyethylene terephthalate material is prepared by taking refined terephthalic acid solution, dibasic acid, ethanediol, dihydric alcohol and graphene oxide and ethanediol solution, modulating into slurry, transporting into esterification reaction kettle for first esterifying under nitrogen atmosphere at 250-265 degrees C for 3-56 hours at 0-0.3 MPa, adding catalyst to monomer, placing into pre-polycondensation reaction kettle at 265-275 degrees C for 1-1.5 hours at 1-30 KPa, sending into final polycondensation tank for condensation polymerization, increasing viscosity increase to 0.60 dl/g, final polycondensing to 275-282 degrees C for 1-2 hours at less than 130 Pa, pumping into sprinkle strip board, extruding, and cold water quenching.
