The utility model discloses nylon layer can play effect high temperature resistant and that promote the film strength, and in the aided forming operation of vacuum, this kind of film both can have been worked as the vacuum bag and used, another, polypropylene isolation layer and epoxy and phenol -formaldehyde resin have good partition performance, can guarantee that also can follow the product surface behind the resin contact membrane peels off.
Description
Technical field
This utility model relates to vacuum bag film technical field, is related specifically to a kind of vacuum with isolation features
Bag film.
Background technology
The most common isolating membrane, owing to material therefor is nonpolar polymeric material, thin film
Intensity is relatively low；And the most common vacuum bag film, its outer layer is nylon (PA) material, and PA thin film is originally
Body has higher mechanical property and higher fusing point, can as the vacuum bag of vacuum assisted resin infusion, but by
It is highly polar material in PA, easy and other resin compatibles, not there is isolation effect, can cause in the demoulding
During produce trouble, damage product.
But for the deficiencies in the prior art, developer be necessary to develop a kind of reasonable in design, simple in construction,
Polypropylene barrier layer has well-separated performance with epoxy resin and phenolic resin, it is ensured that resin contacts
Also the vacuum bag film with isolation features can peeled off from product surface after thin film.
Utility model content
For solving the problem that prior art exists, this utility model provide a kind of reasonable in design, structure is simple
Single, polypropylene barrier layer has well-separated performance with epoxy resin and phenolic resin, it is ensured that resin
Also the vacuum bag film with isolation features can peeled off from product surface after contact thin film.
For solving above technical problem, this utility model realizes by the following technical solutions:
A kind of vacuum bag film with isolation features, it is characterised in that include nylon layer, a TIE bonding
Resin bed, polyethylene layer, the 2nd TIE bonding resin layer and polypropylene barrier layer, described nylon layer is by the
One TIE bonding resin layer is bonded in the upside of polyethylene layer, and described polypropylene barrier layer is glued by the 2nd TIE
Resin layer is bonded in the downside of polyethylene layer.
In a preferred embodiment of the present utility model, uniform at the lower surface of described polypropylene barrier layer
It is distributed with multiple salient point.
In a preferred embodiment of the present utility model, the thickness of described nylon layer is 23-29 μm, institute
The thickness stating a TIE bonding resin layer is 20-30 μm, and the thickness of described polyethylene layer is 24-28 μm,
The thickness of described 2nd TIE bonding resin layer is 25-30 μm, and the thickness of described polypropylene barrier layer is
25-30μm。
Compared with prior art, this utility model nylon layer can play high temperature resistant and promote film strength
Effect, in vacuum assisted resin infusion operation, this kind of thin film both can have been worked as vacuum bag and used；Another, poly-
Propylene sealing coat has well-separated performance with epoxy resin and phenolic resin, it is ensured that resin contact is thin
Also can peel off from product surface after film.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will
The accompanying drawing used required in embodiment or description of the prior art is briefly described, it should be apparent that,
Accompanying drawing in describing below is only embodiments more of the present utility model, for ordinary skill people
From the point of view of Yuan, on the premise of not paying creative work, it is also possible to obtain the attached of other according to these accompanying drawings
Figure.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.
With reference to shown in Fig. 1-Fig. 3, a kind of vacuum bag film with isolation features be given in figure, including nylon
Layer the 100, the oneth TIE bonding resin layer 200, polyethylene layer the 300, the 2nd TIE bonding resin layer 400 and poly-
Propylene sealing coat 500.
Nylon layer 100 is bonded in the upside of polyethylene layer 300, nylon by a TIE bonding resin layer 200
Layer 100 can play effect that is high temperature resistant and that promote film strength, in vacuum assisted resin infusion operation, this kind
Thin film both can have been worked as vacuum bag and used.
Polypropylene barrier layer 500 is bonded in polyethylene layer 300 times by the 2nd TIE bonding resin layer 400
Side, polypropylene barrier layer 500 has well-separated performance with epoxy resin and phenolic resin, it is ensured that tree
Also can peel off from product surface after fat contact thin film, further increase the isolation effect of this vacuum bag film.
Lower surface at polypropylene barrier layer 500 is uniformly distributed and is provided with multiple salient point 510, the setting of salient point 510
Make polypropylene barrier layer 500 be more easily peelable with epoxy resin and phenolic resin, further increase this vacuum
The isolation performance of bag film.
The thickness of nylon layer 100 is 23-29 μm, and the thickness of nylon layer 100 is 25 μm in the present embodiment,
The thickness of the oneth TIE bonding resin layer 200 is 20-30 μm, in the present embodiment a TIE bonding resin layer
The thickness of 200 is 25 μm, and the thickness of polyethylene layer 300 is 24-28 μm, in the present embodiment polyethylene layer
The thickness of 300 is 25 μm, and the thickness of the 2nd TIE bonding resin layer 400 is 25-30 μm, at the present embodiment
In the thickness of the 2nd TIE bonding resin layer 400 be 25 μm, the thickness of polypropylene barrier layer 500 is
25-30 μm, the thickness of polypropylene barrier layer 500 is 25 μm in the present embodiment.
Draw through long-term test, only when thickness, a TIE bonding resin layer 200 of nylon layer 100
Thickness, the thickness of polyethylene layer 300, the thickness of the 2nd TIE bonding resin layer 400 and polypropylene barrier layer
