Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the compound barrier schematic diagram of a layer structure of water oxygen of the utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of high barrier low transparency moisture proof PET composite membrane, including the upper layer PET set gradually
The compound barrier layer 2 of base copolyester 1, water oxygen and lower layer's PET base copolyester 3；Above-mentioned trilaminate material is using co-extrusion technology through two-way drawing
It stretches obtained.
PET film length is damp and mouldy in order to prevent, when design, can be provided in the upper surface of the upper layer PET base copolyester 1
First polyacrylamide amine layer 11, and the upper surface of the first polyacrylamide amine layer 11 is provided with polyvinyl chloride layer 110, it is described poly-

111。
Due to being provided with the first polyacrylamide amine layer and the second polyacrylamide amine layer, so that PET film integrally can be obstructed effectively
Oxygen, vapor penetrate PET film, and set respectively in the lower surface of the upper surface of polyvinyl chloride layer and the second polyacrylamide amine layer
It is equipped with nano fluoropolymer particle layer, can further prevent PET film by the corrosion of humid air, moisture etc., it can be significantly
Extend the service life of PET film.
In Fig. 2, the compound barrier layer 2 of water oxygen includes the boron nitride nanometer layer 21 that top upper layer is arranged in, and is arranged in
Between upper layer evoh layer 22, the water-soluble polymer layer 23 in intermediate middle layer is set, is arranged in immediate underlying layer
Polyvinylamine-polyvinyl alcohol copolymer layer 24, and the graphene nano layer 25 of lower part lower layer is set；Wherein, the nitrogen
Change boron nanometer layer with a thickness of 100-180nm, the evoh layer with a thickness of 50-70nm, the water solubility
