Description
Technical field
The utility model is related to a kind of fiber reinforcement type high performance composite films.
Background technology
Composite membrane material has low table due to having the performances such as weatherability, durability, good non-adhesive
Face tension, low frictional properties hate repellency, hate the special surface propertys such as reprimand oiliness, and are produced in aerospace and precise electronic
The encapsulation field of product is widely used；And existing composite membrane material is due to the limitation of material and structure, it is whole
Body intensity and peel strength still do not reach requirement in special use environment.
Utility model content
For the above technical problems, the purpose of this utility model is：Propose a kind of fiber reinforcement type high-performance
Laminated film.
What the technical solution of the utility model was realized in：A kind of fiber reinforcement type high performance composite film, packet
Containing external protection, basal layer and enhancement layer, external protection is PVDF thin film, and basal layer is aluminium foil, and enhancement layer is along warp-wise and latitude
To the fibre bundle of laying；The external protection is arranged by binder in the side of basal layer, and it is in net that enhancement layer, which is pressed through broadwise,
Trellis is layed in the another side of base layer, and the interlaminar strength of external protection and basal layer is not less than 3 pounds per inch, outer protection
The whole overall thickness of layer, basal layer and enhancement layer is 35 μm -100 μm.
Preferably, the thickness of the external protection is 18-25 microns.
Preferably, the thickness of the basal layer is 6.5-12 μm.
Preferably, the fibre bundle is nylon or aramid fiber, and parallel and spacing distance is between fibre bundle
2.5mm-10mm, fibre bundle pass through binder-impregnated before being laid with and handle.
Preferably, the binder is made of acetone, VMA and polyurethane, and the ratio of acetone, VMA and polyurethane is 1：3：
0.4。
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
The fiber reinforcement type high performance composite film of the utility model is film as external protection using PVDF, is with aluminium foil
Basal layer makes entirety have the basic properties such as good weatherability, durability using fibre bundle as enhancement layer；External protection with
Basal layer is bonded by special binder, improves peel strength, and using fibre bundle as enhancement layer, is improved whole strong
Degree.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of structural schematic diagram of fiber reinforcement type high performance composite film of the utility model.
Specific implementation mode
Illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Fig. 1, a kind of fiber reinforcement type high performance composite film described in the utility model, including external protection
1, basal layer 2 and enhancement layer 3；The external protection 1 is PVDF thin film, and the thickness of external protection 1 is 18-25 microns；The base
Plinth layer 2 is aluminium foil, and the thickness of basal layer 2 is 6.5-12 μm；The enhancement layer 3 is the fibre bundle being laid with along warp-wise and broadwise,
Fibre bundle is nylon or aramid fiber, and parallel and spacing distance is 2.5mm-10mm between fibre bundle, and fibre bundle is laid with
Preceding binder-impregnated of passing through is handled；The external protection 1 is arranged by binder in the side of basal layer 2, and enhancement layer 3 is by warp
Broadwise is in the latticed another side for being layed in base layer, and external protection 1 and the interlaminar strength of basal layer 2 are not less than 3 pounds/English
Very little, the whole overall thickness of external protection 1, basal layer 2 and enhancement layer 3 is 35 μm -100 μm；The binder is by acetone, VMA
Ratio with the glue of polyurethane composition, acetone, VMA and polyurethane is 1：3：0.4.
The preparation method of the laminated film is as follows：Glue is laid on aluminium foil, by PVDF and aluminium foil hot melt compounding machine
Compound, temperature is 75-85 DEG C, drum pressure 4kg, is then placed on curing 2 days in curing chamber, and curing temperature is 35-45 DEG C；Most
Combination product is placed on hot press afterwards, glue is layed on aluminium foil, fibre bundle is placed on aluminium foil, hot pressing temperature 90
DEG C, time 45s is spaced 20min, repeats hot pressing 3 times.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
