Description
Technical Field
The utility model belongs to the technical field of the plastic-aluminum membrane preparation technique and specifically relates to indicate a novel plastic-aluminum membrane is with high internal stress multilayer body.
Background
At present, the technology of the lithium ion battery is mature day by day, and the soft package aluminum plastic film is widely applied to the fields of 3C electronic products, power batteries, energy storage and the like due to the advantages of light weight, safety and the like. In the processing process, because the internal stress of the nylon film in the soft-package aluminum-plastic film is greater than that of the polypropylene film, the soft-package aluminum-plastic film is easy to warp, and a leveling procedure is required to be added in severe cases, so that the working efficiency can be greatly reduced.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model discloses to the disappearance that prior art exists, its main objective provides a novel high internal stress multilayer body for plastic-aluminum membrane, and it can avoid soft package plastic-aluminum membrane to appear warping phenomenon, need not increase the flattening process, can improve work efficiency.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a novel high internal stress multilayer body for an aluminum plastic film comprises an annular polyolefin substrate layer, a glue layer and a sealing layer, wherein the glue layer and the sealing layer are respectively arranged on the upper surface and the lower surface of the annular polyolefin substrate layer, and the sealing layer is an ethylene-propylene copolymer film layer.
Preferably, the thickness of the cyclic polyolefin substrate layer is 18-72 μm.
As a preferable scheme, the thickness of the glue layer is 3-18 μm.
Preferably, the thickness of the sealing layer is 3-18 μm.
Preferably, the glue layer is a maleic anhydride grafted polypropylene resin film layer.
Preferably, the glue layer and the sealant layer have the same thickness, and the ratio of the thickness of the sealant layer to that of the cyclic polyolefin substrate layer is in the range of 1/8 to 1/3.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme, it mainly is through setting up cyclic annular polyolefin substrate layer, and it can improve the internal stress, plays the effect of support to can avoid soft packet of plastic-aluminum membrane warpage's phenomenon to appear, just so need not increase the flattening process, can improve work efficiency.
To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
