The utility model discloses a set up colored adhesive layer between protective layer and aluminium foil layer (AL) for different colours can be made to the plastic -aluminum mould, and the plastic -aluminum membrane that different thickness, different material were made can be distinguished through different colours, has improved the degree of discerning of plastic -aluminum membrane, the condition that the material is obscured appears when having avoided battery assembly manufacturing, has improved battery assembly manufacturing's production efficiency, has guaranteed the stability of battery quality, has reduced the production cost.
Description
Technical field
The aluminum plastic film that the utility model relates to lithium battery makes art, is specifically related to a kind of dumb light Aluminium plastic film.
Background technology
At present along with the development of lithium electrical travelling industry, increasing to the demand of plastic-aluminum packaging film, also get up high to the quality requirement of lithium battery.Conventional plastic-aluminum packaging film is generally formed by the Film laminated of three layers of difference in functionality; skin is as protective layer by nylon film; centre is insulating barrier aluminium foil; internal layer is hot sealing layer cast polypropylene film, and the aluminum plastic film appearance color drawn thus is single, causes identification not high; obscuring of material is easily caused in the assembling of battery is produced; bring unnecessary trouble to production, affect the production efficiency of lithium battery, add production cost.Meanwhile, the quality of prepared battery also can be caused unstable with wrong material, affect product quality.
Utility model content
The utility model is for the disappearance of prior art existence, and its object is to provide the mold of a kind of dumb light Aluminium, it can improve the identification of aluminum plastic film, improves the production efficiency of lithium battery.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of dumb light Aluminium plastic film; comprise protective layer, tack coat, aluminium foil layer (AL), tack coat and hot sealing layer from outside to inside successively; the material of described protective layer is the one in nylon membrane (PA) and polymer PET (PET); described hot sealing layer is co-polypropylene film (CPP); described protective layer is transparent; and the tack coat between described protective layer and aluminium foil layer (AL) is coloured glue adhesion coating, described coloured glue adhesion coating is add the coloured glue adhesion coating that is mixed to form of dyeing filler by binding agent.
As a kind of preferred version, described binding agent is modified epoxy, acrylic resin modified, organic siliconresin, one of polyimide resin or organic fluorine.
As a kind of preferred version, the outer surface of described protective layer is provided with dumb light layer, and described dumb light layer thickness is 2-10 μm.
As a kind of preferred version, the thickness of described protective layer is 15 ~ 50 μm, and the thickness of described tack coat is 2 ~ 15 μm, and described aluminium foil layer thickness is 20 ~ 100 μm, and described co-polypropylene film (CPP) thickness is 20 ~ 80 μm.
As a kind of preferred version, described aluminium foil layer is also provided with polymer PET (PET) between polypropylene screen (CPP) together, and the thickness of described polymer PET (PET) is 10 ~ 60 μm.
The utility model compared with prior art has obvious advantage and beneficial effect; specifically; by arranging coloured glue adhesion coating between protective layer and aluminium foil layer (AL); make aluminum mold can make different colors; the aluminum plastic film that different-thickness, different materials are made can be distinguished by different colours; improve the identification of aluminum plastic film; avoid when battery assembling is produced and occur the situation that material is obscured; improve the production efficiency that battery assembling is produced; ensure that the stability of battery quality, reduce production cost.Meanwhile, be also provided with dumb light layer at the outer surface of aluminum plastic film, avoid the light pollution situation caused because color is too vivid, make product and working environment more harmonious, staffing effectiveness is higher.
For more clearly setting forth architectural feature of the present utility model, technological means and the specific purposes reached thereof and function, below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the utility model.
Accompanying drawing identifier declaration:
1, protective layer 2, aluminium foil layer (AL) 3, polymer PET (PET)
4, co-polypropylene film (CPP) 5, coloured glue adhesion coating 6, tack coat

Detailed description of the invention
As shown in Figure 1, a kind of dumb light Aluminium plastic film, comprises protective layer 1, tack coat, aluminium foil layer (AL) 2, tack coat and hot sealing layer from outside to inside successively.The material of described protective layer 1 is the one in nylon membrane (PA) and polymer PET (PET); described hot sealing layer is co-polypropylene film (CPP) 4; the thickness of described protective layer 1 is 15 ~ 50 μm; the thickness of described tack coat is 5 ~ 15 μm; described aluminium foil layer thickness is 20 ~ 100 μm, and described co-polypropylene film (CPP) 4 thickness is 20 ~ 80 μm.Described protective layer 1 is transparent, and the tack coat between described protective layer 1 and aluminium foil layer (AL) 2 is coloured glue adhesion coating 5, and described coloured glue adhesion coating 5 adds dyeing filler by binding agent and is mixed to form.Described binding agent is modified epoxy, acrylic resin modified, organic siliconresin, one of polyimide resin or organic fluorine.Because described protective layer 1 is transparent; the color of coloured glue adhesion coating 5 clearly can be shown by protective layer 1; staff is made operationally can accurately to differentiate different aluminum plastic films by the color of display; avoid when battery assembling is produced and occur the situation that material is obscured; improve the efficiency that battery assembling is produced, ensure that the stable of battery quality.
For avoiding the color of aluminum plastic film excessively bright, produce light pollution to working environment, affect operating efficiency, the outer surface of described protective layer 1 is provided with dumb light layer 8, and described dumb light layer 8 thickness is 2-10 μm.
For increasing the corrosion resistance of aluminum plastic film, described aluminium foil layer (AL) 2 is also provided with polymer PET (PET) 3 between polypropylene screen (CPP) 4 together, and the thickness of described polymer PET (PET) 3 is 10 ~ 60 μm.
The above, it is only preferred embodiment of the present utility model, not in order to limit the utility model, thus every according to technology of the present utility model actual above embodiment is done any amendment, equivalent replacement, improvement etc., all still belong in the scope of technical solutions of the utility model.
