Abstract
This utility model provides a kind of aluminum plastic film be easy to and encapsulate; the hot sealing layer of the protective layer including outer layer, middle aluminium lamination and internal layer; the two sides of the aluminium lamination is combined with protective layer and hot sealing layer respectively by high-melting-point binding agent, is provided with low melting point adhesive between the protective layer and aluminium lamination and/or between hot sealing layer and aluminium lamination.Low melting point adhesive is provided between protective layer of the present utility model and aluminium lamination and/or between hot sealing layer and aluminium lamination; so low temperature and pressure need to be carried out after unnecessary edge sealing is cut to aluminum plastic film only; low melting point adhesive just can be melted out sealing cutting mouth; the operation of gluing need not be increased; substantial amounts of human cost can thus be saved; this process is advantageously implemented automated production, improves the production efficiency of lithium battery.
Description
Technical field
This utility model is related to aluminum plastic film production technical field, more particularly to a kind of aluminum plastic film for being easy to encapsulate.
Background technology
As the battery core bodies enclosed inside of flexible packing lithium ion battery has electrolyte organic solvent, pretend and pack for which
Aluminum plastic film housing allow for resist electrolyte it is swelling, dissolving, absorb etc., especially for polymer battery.Due to polymerization
Thing lithium-ion electric core body is active individuality, will prevent both positive and negative polarity short circuit conducting, electrochemical corrosion occurs.
Traditional lithium ion battery aluminum plastic film packaging technology generally comprises three steps：1st, battery core surrounding is pointed to first
Plastic-aluminum film edge carries out hot-pressing, edge-sealing；2nd, cut the unnecessary edge sealing of aluminum plastic film；3rd, in the sanction incision gluing of aluminum plastic film, strengthen
Insulating properties at aluminum plastic film trimming, to prevent aluminum plastic film sliced boundary aluminium lamination from generation electrification is contacted with external power source negative pole or metal
Learn corrosion.But automated production the step of gluing, is difficult to, need substantial amounts of labour force to realize, will so produce
The substantial amounts of cost of labor of life, and low production efficiency.
Utility model content
Disappearance of this utility model for prior art presence, there is provided a kind of aluminum plastic film for being easy to encapsulate, which can make plastic-aluminum
Film packaging technology realizes full-automatic production, reduces cost of labor, improve production efficiency.
For achieving the above object, this utility model is using such as purgation technical scheme：
A kind of aluminum plastic film for being easy to encapsulate, including the hot sealing layer of the protective layer, middle aluminium lamination and internal layer of outer layer, the aluminum
The two sides of layer is combined with protective layer and hot sealing layer respectively by high-melting-point binding agent, between the protective layer and aluminium lamination and/or hot
Low melting point adhesive is provided between sealing and aluminium lamination.
Used as a kind of preferred version, the melting temperature of the high-melting-point binding agent is 120-180 degree Celsius.
Used as a kind of preferred version, the melting temperature of the low melting point adhesive is 60-100 degree Celsius.
Used as a kind of preferred version, the protective layer is PA layers or pet layer.
Used as a kind of preferred version, the hot sealing layer is CPP layers.
This utility model compared with prior art, with advantages below and advantage, specifically, the protective layer and aluminium lamination
Between and/or hot sealing layer and aluminium lamination between be provided with a small amount of low melting point adhesive, so only aluminum plastic film need to cut
Low temperature and pressure is carried out after unnecessary edge sealing, low melting point adhesive just can be melted out sealing cutting mouth, make to cut mouth exhausted with the external world
Edge, it is not necessary to increase single coating process, can thus save substantial amounts of human cost, and this process is advantageously implemented certainly
Dynamic metaplasia is produced, and improves the production efficiency of lithium battery.
More clearly to illustrate architectural feature of the present utility model, technological means and its specific purposes for being reached and work(
Can, below in conjunction with the accompanying drawings with specific embodiment being described in further detail to this utility model：

Accompanying drawing identifier declaration：
1- protective layers, 2- aluminium laminations, 3- hot sealing layers, 4- high-melting-point binding agents, 5- low melting point adhesives.
Specific embodiment
As shown in figure 1, a kind of aluminum plastic film for being easy to encapsulate, including the protective layer 1 of outer layer, middle aluminium lamination 2 and internal layer
Hot sealing layer 3, the two sides of the aluminium lamination 2 are combined with protective layer 1 and hot sealing layer 3 respectively by high-melting-point binding agent 4, the protective layer
A small amount of low melting point adhesive 5 is provided between 1 and aluminium lamination 2.The melting temperature of the high-melting-point binding agent 4 is that 120-180 is Celsius
Degree.The melting temperature of the low melting point adhesive 5 is 60-100 degree Celsius.The protective layer 1 is PA layers or pet layer.The heat
Sealing 3 is CPP layers.
Another embodiment of this utility model is illustrated in figure 2, which with the difference of above-described embodiment is：The heat
A small amount of low melting point adhesive 5 is provided between sealing 3 and aluminium lamination 2.
The another embodiment of this utility model is illustrated in figure 3, which with the difference of above-described embodiment is：The guarantor
A small amount of low melting point adhesive 5 is equipped between sheath 1 and aluminium lamination 2 and hot sealing layer 3 and aluminium lamination 2 between.
The above, is only preferred embodiment of the present utility model, not to limit this utility model, thus it is every
Any modification, equivalent substitution and improvements actually made to above example according to technology of the present utility model etc., still fall within this
In the range of utility model technical scheme.
