Abstract
The invention discloses a lithium battery packaging film with high barrier, acid resistance and alkali resistance, which is manufactured through the following steps of: using a special aluminum alloy aluminum layer as an intermediate base layer, thermally processing the aluminum alloy aluminum layer, respectively plating a layer of functional nanometer silicon material on the upper and lower surface layers of the aluminum alloy aluminum layer, thermally processing through a special process, processing an inner layer and an outer layer with a nanometer barrier and an insulating coating liquid twice; and attaching a layer of high-strength nylon layer to the outer layer of the aluminum alloy aluminum layer, and attaching a layer of polypropylene layer made from nanometer macromolecular materials to the inner layer of the aluminum alloy aluminum layer. By adequately adopting the extreme flexibility, ductility performance, extremely high corrosion resistance and barrier performance of alloy aluminum foil after the alloy aluminum foil is functionally processed, the manufactured lithium battery packaging film has excellent performances such as excellent insulation, cold punching resistance, corrosion resistance, high barrier, high strength and the like.
Description
Technical field
The present invention relates to the battery acid packaging film that lithium celies such as automobile, mobile phone, computer use, concrete is the lithium battery packaging film of a kind of high-barrier, acid and alkali-resistance.
Background technology
(patent No.: ZL02163383.6) disclose a kind of lithium battery flexible packaging film is based on common aluminium lamination to Chinese patent, its internal layer polycaprolactam or poly-adipoyl be the diamines layer, skin is that common double is to the tensile nylon layer, and other similar utility model patents, the defective of the common functionality that they exist at present is: 1. aluminium lamination ruptures when cold stamping shaped easily, causes electrolyte leakage.2. barrier property is poor, because of power tensile property difference between nylon layer and the aluminium foil layer, causes nylon layer and the easy layering of aluminium lamination when cold stamping shaped, thereby causes barrier property to descend.3. the insulation of aluminium lamination and corrosion-resistance treatment are not enough, cause moulding flexible packaging film insulating power poor, easily produce internal layer flatulence, or are punctured by electrode.Battery reject rate height, service life is short.Above main function defective exists, and is that present flexible packed lithium film is failed the major cause widely used in market always.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind ofly have splendid insulation, cold-resistantly dash, the high-barrier of excellent properties such as withstanding corrosion, high-barrier, high strength, the lithium battery packaging film of acid and alkali-resistance.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The lithium battery packaging film of a kind of high-barrier, acid and alkali-resistance, it is the intermediate base layer with the particular aluminum alloy aluminium lamination, adhere to the high-intensity nylon layer of one deck on the upper strata of described aluminum alloy aluminium lamination, be coated with one deck functional nano silicon materials between described aluminum alloy aluminium lamination and the nylon layer; Adhere to the polypropylene layer that one deck nano-macromolecule material makes in the lower floor of described aluminum alloy aluminium lamination, be coated with one deck functional nano silicon materials between described aluminum alloy aluminium lamination and the polypropylene layer.
Further, described aluminum alloy aluminium lamination after treatment, it forms by extraordinary acid and alkali-resistance is resin-bonded with polypropylene layer and nylon layer respectively up and down.
Further, metals such as manganese, nickel have been added in the described aluminum alloy aluminium lamination.
Further, described nylon layer is by nylon and polypropylene co-extrusion gained.
Further, described polypropylene layer is nylon and PVDC and Polymer polypropylene co-extrusion gained.
Preferably, the thickness of described aluminum alloy aluminium lamination is the 30-60 micron for degree.
Preferably, the thickness of described nylon layer is the 20-35 micron.
Preferably, the thickness of described polypropylene layer is the 20-65 micron.
The present invention has following beneficial effect: at first, in the nylon layer of the present invention because polyacrylic existence arranged, itself and aluminum alloy aluminium lamination not only have splendid compound fastness when bonding, peel strength reaches 15N/MM, and be flexible packaging film when cold stamping shaped, have good buffering between aluminium foil and the skin, can not produce demoulding.Then, because polypropylene layer of the present invention is nylon and PVDC and Polymer polypropylene co-extrusion gained, because nylon and PVDC have good intensity and barrier property, Polymer polypropylene layer has splendid elasticity and extension property but also has splendid decay resistance, after itself and aluminium lamination are bonding, both had good cold punching performance, had splendid heat sealability and decay resistance again.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, the lithium battery packaging film of a kind of high-barrier, acid and alkali-resistance, it is the intermediate base layer with particular aluminum alloy aluminium lamination 1, adheres to the high-intensity nylon layer 4 of one deck on the upper strata of described aluminum alloy aluminium lamination 1, is coated with one deck functional nano silicon materials 2 between described aluminum alloy aluminium lamination 1 and the nylon layer 4; Adhere to the polypropylene layer 5 that one deck nano-macromolecule material makes in the lower floor of described aluminum alloy aluminium lamination 1, be coated with one deck functional nano silicon materials 3 between described aluminum alloy aluminium lamination 1 and the polypropylene layer 5.Described aluminum alloy aluminium lamination 1 plates one deck functional nano silicon materials 2,3 after special process heat treatment, levels is again with nanometer obstruct, insulation coating fluid reheat treatment, make the flexible packaging film of making have splendid insulativity and decay resistance, itself and lithium battery electrolytes can not produce when packing and phenomenons such as aluminium lamination conduction or flatulence.
Further, described aluminum alloy aluminium lamination 1 after treatment, it forms by extraordinary acid and alkali-resistance is resin-bonded with polypropylene layer 5 and nylon layer 1 respectively up and down.
