Housing is constituted.The chemical property of lithium ion battery active ingredient is all very active, is placed in air and is easy to catch fire or even explodes,
Thus the packaging shell of lithium ion battery should have certain corrosion resistance and very excellent barrier, at present conventional packaging
Mainly there are box hat, aluminum hull and high molecular aluminium plastic film.Battery is packed using aluminum-plastic composite membrane, have the advantages that it is lightweight,
The specific energy of battery can significantly be lifted.And laminated aluminum film film has very big flexibility, can effectively reduce electricity
The internal pressure in pond, is not in explosion danger.
And existing aluminum plastic film product is when hot environment or close burning things which may cause a fire disaster, it is easy to fire the protective layer of aluminum plastic film
Burn, so as to influence the security performance of battery.
Utility model content
The utility model is in view of the existing deficiencies of the prior art there is provided a kind of aluminum plastic film of good flame resistance, and it can improve aluminium
The fire resistance of plastic film protective layer, improves security of the aluminum plastic film in hot environment or close burning things which may cause a fire disaster, ensures that electricity
The security performance in pond.
To achieve the above object, the utility model is using following technical scheme：
A kind of aluminum plastic film of good flame resistance, includes the hot sealing layer of the protective layer of outer layer, middle aluminium lamination and internal layer, the aluminium
The two sides of layer is combined with protective layer and hot sealing layer respectively by adhesive, and the protective layer is fire-retardant nylon material layer.This practicality
In new, the fire-retardant nylon material layer is added in nylon material the system by way of melting co-extrusion by aluminum diethylphosphinate
It is standby to obtain.
As a kind of preferred scheme, the thickness of the protective layer is 5-50 μm.
As a kind of preferred scheme, the thickness of the protective layer is 25 μm.
As a kind of preferred scheme, the grain diameter D90 of the aluminum diethylphosphinate is 20-500nm.
As a kind of preferred scheme, the grain diameter D90 of the aluminum diethylphosphinate is 200nm.
As a kind of preferred scheme, the hot sealing layer is CPP layers or PPA layers.
In the utility model：By using aluminum diethylphosphinate the process that PA melts co-extrusion, shape are added as fire retardant
Into the fire-retardant nylon material layer of anti-flammability.The addition of fire retardant aluminum diethylphosphinate to the PA layers of aluminum plastic film burning process
It is middle to be chemically reacted, make PA thermal degradation disequilibrium, accelerate aluminum plastic film surface into the process of charcoal.With fire retardant diethyl
The addition of base phosphinic acids aluminium is scaling up, and the solid phase ratio increase of flame-retardant system, the release with respect to imflammable gas is reduced,
The fire resistance of the PA layers of aluminum plastic film is improved, security of the aluminum plastic film in hot environment or close burning things which may cause a fire disaster is improved, really
The security performance of the battery using the laminated aluminum film is protected.
Compared with prior art, with advantages below and advantage, specifically, the protective layer is addition to the utility model
There is the fire-retardant nylon material layer of aluminum diethylphosphinate, it follows that aluminum diethylphosphinate is added to PA layers as fire retardant,
The fire resistance of the PA layers of aluminum plastic film is got a promotion, improve safety of the aluminum plastic film in hot environment or close burning things which may cause a fire disaster
Property, it is ensured that use the security performance of the battery of the laminated aluminum film.
For the specific purposes and work(for more clearly illustrating architectural feature of the present utility model, technological means and its being reached
Can, the utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model.

Embodiment
As shown in figure 1, a kind of aluminum plastic film of good flame resistance, 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 is combined with protective layer 1 and hot sealing layer 3 respectively by adhesive 4, and the protective layer 1 is resistance
Fire nylon material layer.The fire-retardant nylon material layer is added in nylon material by melting co-extrusion by aluminum diethylphosphinate
Mode is prepared.The thickness of the protective layer is 5-50 μm, preferably 25 μm.The grain diameter of the aluminum diethylphosphinate
D90 is 20-500nm, preferably 200nm.The hot sealing layer 3 is CPP layers or PPA layers.
Operation principle of the present utility model：The mistake that PA melts co-extrusion is added as fire retardant using aluminum diethylphosphinate
Journey, forms the fire-retardant nylon material layer of anti-flammability.The addition of fire retardant aluminum diethylphosphinate is to the PA layers of aluminum plastic film in burning
During chemically reacted, make PA thermal degradation disequilibrium, accelerate aluminum plastic film surface into the process of charcoal.With fire-retardant
The addition of agent aluminum diethylphosphinate is scaling up, the solid phase ratio increase of flame-retardant system, with respect to releasing for imflammable gas
Reduction is put, the fire resistance of the PA layers of aluminum plastic film is improved, peace of the aluminum plastic film in hot environment or close burning things which may cause a fire disaster is improved
Quan Xing, it is ensured that use the security performance of the battery of the laminated aluminum film.
