Abstract
The utility model discloses a vacuum bag membrane of high nylon content suitable for shaping of preimpregnation material, including the outer and compound nylon inlayer of compound nylon, bond through the polyester adhesive phase between the outer and compound nylon inlayer of compound nylon, the outer nylon weight ratio content with compound nylon inlayer of compound nylon all is not less than 70%, and the thickness between outer, compound nylon inlayer of compound nylon and the polyester adhesive phase all is not less than 50 microns. The utility model discloses a three -layer composite's mode, middle level adopt the polyester adhesive phase, provide good toughness and are used for improving the intrinsic fragility of nylon itself, and the outer nylon content with compound nylon inlayer of compound nylon all is not less than 70%, ensure in the use requirement to temperature resistant and intensity, and the requirement to the high vacuum degree is satisfied in the whole solidification process of finished piece in the assurance. The utility model discloses reduced the degree of difficulty of the production process of bag membrane own, improved product yield, effective reduce cost for the product more is favorable to big popularization in batches.
Description
Technical field
The utility model relates to vacuum bag field, particularly a kind of vacuum bag film being applicable to the shaping high nylon content of prepreg.
Background technology
The vacuum bag film being generally used for prepreg moulding process is pure nylon material, because need high-temperature resistant and the high-intensity performance of using nylon.For large batch of large-scale wind electricity prepreg profiled part, heatproof requires general lower than 170 DEG C, only needs heating cure, without autoclave molding, so require slightly low, simultaneously for reducing costs urgent requirement for the heatproof of vacuum bag film and strength character.In addition, also have vacuum bag film to be adopt nylon and polyethylene to form by glue layer is bonding at present, but the vacuum bag film of this structure can not solve nylon membrane fragility inherently, the production difficulty of vacuum bag film is large, reduces finished product rate.
Utility model content
The purpose of this utility model is for shortcomings and deficiencies of the prior art, provides a kind of vacuum bag film being applicable to the shaping high nylon content of prepreg, to solve the problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of vacuum bag film being applicable to the shaping high nylon content of prepreg, it is characterized in that, comprise composite nylon skin and composite nylon internal layer, bonding by polyester binding oxidant layer between described composite nylon skin and composite nylon internal layer, described composite nylon nylon weight ratio content that is outer and composite nylon internal layer is all not less than 70%, and outer, between composite nylon internal layer and polyester binding oxidant layer the thickness of described composite nylon is all not less than 50 microns.
In a preferred embodiment of the present utility model, described composite nylon skin and composite nylon internal layer are composited by PE, adhesive and nylon.
Owing to have employed technical scheme as above, the utility model adopts the mode of three layers of compound, middle level adopts polyester binding oxidant layer, good toughness is provided to be used for improving nylon fragility inherently, composite nylon nylon content that is outer and composite nylon internal layer is all not less than 70%, guarantee the requirement for resistance to gentle intensity in use procedure, ensure the requirement met to condition of high vacuum degree in the whole solidification process of product.The design of the utility model composite bed also reduces the difficulty of the production process of bag film own, improves finished product rate, effectively reduces costs, make product more be conducive to popularization in enormous quantities.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below.
A kind of vacuum bag film being applicable to the shaping high nylon content of prepreg shown in Figure 1, comprise composite nylon outer 10 and composite nylon internal layer 30, bonding by polyester binding oxidant layer 20 between composite nylon outer 10 and composite nylon internal layer 30, polyester binding oxidant layer 20 provides good toughness to be used for improving nylon fragility inherently.The nylon weight ratio content of composite nylon outer 10 and composite nylon internal layer 30 is all not less than 70%, guarantees the requirement for resistance to gentle intensity in use procedure, ensures the requirement met to condition of high vacuum degree in the whole solidification process of product.Composite nylon skin 10, thickness between composite nylon internal layer 30 and polyester binding oxidant layer 20 are all not less than 50 microns, ensure that normal working strength.Preferred composite nylon outer 10 and composite nylon internal layer 30 are composited by PE, adhesive and nylon.
The design of the utility model composite bed also reduces the difficulty of the production process of bag film own, improves finished product rate, effectively reduces costs, make product more be conducive to popularization in enormous quantities.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
