8): (1~2).The thickness of presently commercially available polypropylene film has 80 μm and 40 μm two kinds, polypropylene film provided in the present invention
It can be prepared according to above two thickness specification；It is understood that polypropylene is thin in the case where not influencing battery performance
The thickness of film is bigger, and the effect for preventing hydrofluoric acid from passing through is better.
Any suitable mesoporous material in this field can be used in mesoporous material, according to some embodiments of the present invention, mesoporous
The combination of any one or two kind of the material in mesopore silicon oxide or meso-porous alumina；The porous structure of mesoporous material can be with
Increase the contact area of rare-earth salts and hydrofluoric acid, thus capture ability of the enhancing to fluorine ion, other realities according to the present invention
Example is applied, the particle size range for controlling mesoporous material is 0.1~5 μm, preferably 0.1~3 μm；If the partial size of mesoporous material less than 0.1 μm,
It is unfavorable for dispersion of the mesoporous material in polypropylene film, is also easy to produce reunion, so as to cause always contacts for rare-earth salts and hydrofluoric acid
Area is less than normal, so that polypropylene film obtained is low to the capture ability of fluorine ion, it is more difficult to realize and hydrofluoric acid is prevented to pass through poly- third
The effect of alkene film layer；If the partial size of mesoporous material is greater than 5 μm, the mechanical property of polypropylene film obtained will affect, such as
Tensile strength decline, elongation at break reduction etc..Other embodiments according to the present invention, it is also necessary to control the hole of mesoporous material
Diameter distribution is 2~50nm, and specific surface area range is 150~500m2/g；If the aperture of mesoporous material is excessive, same particle size
Under mesoporous material, corresponding specific surface area is small, can not only make polypropylene film obtained low to the capture ability of fluorine ion,
There is also due to aperture it is bigger than normal so that hydrofluoric acid is added into layer directly through corresponding, promote hydrofluoric acid instead across poly- third
Alkene film layer, plays reverse effect.

To improve the ability that layer of polypropylene foil prevents hydrofluoric acid from passing through within the scope of this, it should be noted that when load capacity is lower than
When 0.01%, the polypropylene film being prepared is low to the capture ability of fluorine ion, it is more difficult to realize and hydrofluoric acid is prevented to pass through poly- third
The effect of alkene film layer；When load capacity is higher than 5%, due to having used more rare-earth salts, cause cost of material higher.Specifically
, in some currently preferred embodiments of the present invention, the load capacity of rare-earth salts accounts for the mesoporous material gross mass of supported rare earth salt
0.05~2%, by the way that the ability that layer of polypropylene foil prevents hydrofluoric acid from passing through can be improved in load capacity control in the range,
Cost of material will not be made higher simultaneously.
Rare-earth salts can be supported on mesoporous material using any suitable way in this field, of the invention some
It is preferably ultrasonic by the way that mesoporous material is immersed in 0.3~1h of ultrasound in the rare-earth salt solution of 0.05~0.5mol/L in embodiment
0.4~0.6h is well dispersed in mesoporous material in rare-earth salt solution；(negative-pressure adsorption), mistake are successively vacuumized after ultrasound again
Filter, the dry mesoporous material that supported rare earth salt can be obtained, wherein the load capacity of rare-earth salts can impregnate front and back according to mesoporous material
Mass Calculation obtain；In other embodiments of the invention, Jie that supported rare earth salt can be obtained is roasted again after drying
Porous materials.
The mesoporous material of supported rare earth salt is contained in polypropylene film provided by the invention, the supported rare earth salt it is mesoporous
Layer of polypropylene foil can be improved to the capture ability of fluorine ion in hydrofluoric acid, to prevent hydrofluoric acid from passing through polypropylene film in material
Layer, prevents the agent of hydrofluoric acid corrosive bond and aluminium foil, meanwhile, the mesoporous material of the supported rare earth salt can also improve polypropylene film
Mechanical property improves the punctured resistance of polypropylene film, so that synthesis improves the aluminum plastic film comprising the polypropylene film
Safety in utilization.
Based on this, the present invention also provides the preparation methods of above-mentioned polypropylene film, according to some embodiments of the present invention,
The preparation method includes the following steps: successively to weigh each component that hot sealing layer, supporting layer and adhesive layer include, be uniformly mixed respectively
Fusion plastification is carried out respectively in Yu Santai extruder afterwards, to respectively obtain the hot sealing layer, supporting layer and the molten mass of adhesive layer；So
Three layers are carried out after the molten mass of the hot sealing layer, supporting layer and adhesive layer is filtered afterwards in triple extrusion die head altogether
It squeezes, then is cast on the chill roll of any surface finish and is quickly cooled to film, wherein the temperature setting range of chill roll is 20~35
