Abstract
The utility model discloses a high-barrier biaxially oriented polyamide film, which comprises a substrate layer, wherein one side of the substrate layer is provided with a first barrier layer, one side of the first barrier layer is provided with a first protective layer, one side of the substrate layer, which is far away from the first barrier layer, is provided with a second barrier layer, one side of the second barrier layer is provided with a second protective layer, and the high-barrier biaxially oriented polyamide film is coated on the outer surface of the substrate layer by arranging the first barrier layer and the second barrier layer on the upper side and the lower side of the substrate layer and adopting vinyl alcohol copolymer to coat the first barrier layer and the second barrier layer, so that the high-barrier biaxially oriented polyamide film has higher elasticity, wear resistance and stronger antistatic property; the first protective layer and the second protective layer formed by the polypropylene coating layer effectively improve the surface corrosion resistance of the film; the utility model discloses a multilayer structure's combination setting can effectively improve the antistatic and anticorrosive effect of polyamide film.
Description
Technical Field
The utility model relates to a polyamide film relevant goods field specifically is a high resistant separates biaxial stretching polyamide film.
Background
As is well known, a polyamide film is produced from a nylon resin by a T-die film forming method, a T-die biaxially stretched film forming method and an inflation method (biaxially stretched film). A resin material having a high viscosity should be used. Commercially available films are mainly films of nylon 6 and nylon 66. The nylon film has the characteristics of high strength, good oxygen barrier property, good transparency and the like.
However, the existing biaxial stretching polyamide film has the defects of simple structure, limited barrier property, low integral corrosion resistance and high defect.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high resistant separates biaxial stretching polyamide film and can improve the whole heat-proof quality of roofing through the integration of multilayer thermal-insulated structure, reduces the thermal transmission of sunshine to solve the problem of proposing among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high resistant separates biaxial stretching polyamide film, includes the substrate layer, one side of substrate layer is equipped with first barrier layer, one side of first barrier layer is equipped with first inoxidizing coating, one side that first barrier layer was kept away from to the substrate layer is equipped with the second barrier layer, one side of second barrier layer is equipped with the second inoxidizing coating.
Preferably, the first barrier layer and the second barrier layer are both made of vinyl alcohol copolymer.
Preferably, the first protective layer and the second protective layer are both polypropylene coating layers.
Compared with the prior art, the beneficial effects of the utility model are that:
according to the high-barrier biaxially oriented polyamide film, the first barrier layer and the second barrier layer are arranged on the upper side and the lower side of the base material layer and are wrapped on the outer surface of the base material layer by adopting the vinyl alcohol copolymer, so that the high-barrier biaxially oriented polyamide film has high elasticity, wear resistance and strong antistatic property; the first protective layer and the second protective layer formed by the polypropylene coating layer effectively improve the surface corrosion resistance of the film; the utility model discloses a multilayer structure's combination setting can effectively improve antistatic and anticorrosive effect of polyamide film
Drawings
Fig. 1 is a schematic structural diagram of a high-barrier biaxially-oriented polyamide film according to the present invention.
In the figure: 1. a substrate layer; 2. a first barrier layer; 3. a first protective layer; 4. a second barrier layer; 5. a second protective layer.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, the present invention provides an embodiment: the utility model provides a high resistant separates biaxial stretching polyamide film, includes substrate layer 1, and one side of substrate layer 1 is equipped with first barrier layer 2, and one side of first barrier layer 2 is equipped with first inoxidizing coating 3, and one side that first barrier layer 2 was kept away from to substrate layer 1 is equipped with second barrier layer 4, and one side of second barrier layer 4 is equipped with second inoxidizing coating 5
Furthermore, the first barrier layer 2 and the second barrier layer 4 are both made of vinyl alcohol copolymer.
Further, the first protective layer 3 and the second protective layer 5 are both polypropylene coating layers.
The working principle is as follows: firstly, arranging a first barrier layer 2 and a second barrier layer 4 on the upper side and the lower side of a substrate layer 1, wrapping the first barrier layer and the second barrier layer on the outer surface of the substrate layer 1 by adopting vinyl alcohol copolymers, and having high elasticity, wear resistance and antistatic property; the first protective layer 3 and the second protective layer 5 formed by the polypropylene coating layer effectively improve the surface corrosion resistance of the film.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
