▎ 摘　　要

NOVELTY - Polyethylene terephthalate material with high barrier properties comprises 70-80 pts. wt. polyethylene terephthalate, 20-30 pts. wt. polylactic acid, 1-5 pts. wt. nano titanium dioxide, 3-5 pts. wt. antioxidant, 1-2 pts. wt. nano calcium carbonate, and 1-1.5 pts. wt. silane coupling agent; the silane coupling agent is dodecyltrimethoxysilane, γ-glycidoxypropyltrimethoxysilane and/or γ-aminopropyltriethoxysilane. USE - The polyethylene terephthalate material with high barrier performance is used to prepare packaging bottles (claimed). ADVANTAGE - The polyethylene terephthalate material solves the problem of unsatisfactory barrier properties of PET packaging materials in the prior art. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing polyethylene terephthalate material with high barrier property, comprising mixing and stirring the raw materials to obtain mixed material, then extruding and granulating the mixed material in a twin-screw extruder, injecting, stretched and blown to obtain polyethylene terephthalate material.
