Abstract
The utility model discloses a kind of low transparency moisture proof PET films, including the upper layer PET base copolyester, non-conductive coating and lower layer's PET base copolyester set gradually；The upper surface of the upper layer PET base copolyester is provided with the first polyacrylamide amine layer, and the upper surface of the first polyacrylamide amine layer is provided with polyvinyl chloride layer, and nano fluoropolymer particle layer is arranged in the upper surface of the polyvinyl chloride layer；The lower surface of the lower layer PET base copolyester is provided with the second polyacrylamide amine layer；And the lower surface of the second polyacrylamide amine layer is provided with nano fluoropolymer particle layer.Due to being equipped with polyvinyl chloride layer in the upper surface of upper layer PET base copolyester in the utility model, so that PET film upper surface has the characteristics that higher heat resistance, flexibility and anti-aging, and very low light transmittance can be reached, so that light will not penetrate PET film substantially, the polyacrylamide amine layer of setting, so that PET film integrally effectively blocking oxygen, vapor can penetrate PET film, it is able to extend the service life of PET film.
Description
Technical field
The utility model relates to a kind of low transparency moisture proof PET films.
Background technique
PET film also known as high temperature resistance polyester film.It has excellent physical property, chemical property and dimensional stability, thoroughly
Bright property, recuperability, can be widely used in magnetic recording, photosensitive material, electronics, electric insulation, industrial film, package decoration,
The fields such as screen protection, the protection of optical grade specular surface.
Currently, the curtain or shower curtain of usually household can be all made of opaque or low light transmission material, in order to reach
To the effect for avoiding privacy from leaking, general way is exactly to coat a coating on a plastic film, but this coating is in high temperature
Under be easy to fall off, and smell is larger, causes screening effect bad, poor user experience.In addition, due to the use of curtain or shower curtain
It can be often subject to the corrosion of rainwater etc., so after long-time use, be easy mouldy, reduce its service life.
Utility model content
The utility model aim is to provide a kind of low transparency moisture proof PET film in view of the defects existing in the prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of low transparency moisture proof PET film, packet
Include the upper layer PET base copolyester, non-conductive coating and lower layer's PET base copolyester set gradually；The upper layer PET base copolyester
Upper surface is provided with the first polyacrylamide amine layer, and the upper surface of the first polyacrylamide amine layer is provided with polyvinyl chloride layer,
Nano fluoropolymer particle layer is arranged in the upper surface of the polyvinyl chloride layer；The lower surface of the lower layer PET base copolyester is arranged
There is the second polyacrylamide amine layer；And the lower surface of the second polyacrylamide amine layer is provided with nano fluoropolymer particle layer.
Wherein, the first polyacrylamide amine layer with a thickness of 2-4um, the second polyacrylamide amine layer with a thickness of 1-
3um。
Wherein, in the nano fluoropolymer particle layer partial size of particle between 20-30nm.
The beneficial effects of the utility model：Non-conductive coating is provided in the utility model makes the water oxygen rejection rate of PET film
Drop to minimum, close to zero, the tension of PET film entirety can be greatly improved, extend the service life of PET film；Due on upper layer
The upper surface of PET base copolyester is equipped with polyvinyl chloride layer, so that PET film upper surface has higher heat resistance, flexibility and resists
The characteristics of aging, and very low light transmittance can be reached, so that light will not penetrate PET film substantially, so with this configuration
The curtain or shower curtain of PET film production can accomplish the effect of masking very well.
In addition, due to being provided with the first polyacrylamide amine layer and the second polyacrylamide amine layer in the utility model, so that PET
Film integrally effectively blocking oxygen, vapor can penetrate PET film, and in the upper surface of polyvinyl chloride layer and the second polyacrylamide
The lower surface of layer is respectively arranged with nano fluoropolymer particle layer, can further prevent PET film by humid air, moisture etc.
Corrosion, the service life of PET film can be greatly prolonged.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Shown in Fig. 1, it is related to a kind of low transparency moisture proof PET film, including the upper layer PET base copolyester 1, non-set gradually
Conductive coating 2 and lower layer's PET base copolyester 3；Above-mentioned trilaminate material is made using co-extrusion technology through biaxial tension.
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-
Nano fluoropolymer particle layer 111 is arranged in the upper surface of pvdc layer 110；The lower surface of the lower layer PET base copolyester 3 is arranged
There is the second polyacrylamide amine layer 31, and the lower surface of the second polyacrylamide amine layer 31 is provided with nano fluoropolymer particle layer
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.
Wherein, in order to reach optimal effect, the first polyacrylamide amine layer 11 with a thickness of 2-4um, described second
Polyacrylamide amine layer 31 with a thickness of 1-3um.
Wherein, in order to reach optimal effect, the partial size of particle is in 20- in the nano fluoropolymer particle layer 111
Between 30nm.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
