PP generally uses the mode of curtain coating to be processed.
According to the difference of processing mode, the mixture of molten state can be done different process, such as, can
In the way of the mixture of molten state is directly used curtain coating, be processed into thin film, and use simple tension or
When the mode of biaxial tension prepares thin film, then generally the mixture of molten state is mixed described by extruder
Compound extrusion plasticizing obtains sheet, the most again the sheet obtained is drawn into thin film at a certain temperature.
Wherein, described mixture extrusion plasticizing is obtained thick by the described extruder that passed through by the mixture of molten state
Sheet concrete operations mode can be, after being mixed by filter and static mixer, dosing pump is delivered to
Head, is then passed through chilling roller and is cooled to sheet, wherein, for different thin film, is prepared as sheet
The temperature in each stage the most difference, such as, extruder transportation section temperature can be 240-260 DEG C, molten
Melting fluxing zone temperature and can be 265-285 DEG C, homogenizing zone temperature can be 270-280 DEG C, filter (net)
Temperature can be 280-285 DEG C, melt line temperature can be 270-275 DEG C, and slab chilling roll temperature can
Think 18-25 DEG C.
Wherein it is desired to explanation, during using the mode of biaxial tension to be processed into thin film, due to
The sheet of acquisition is stretched through longitudinal and transverse direction at a certain temperature, makes the strand of described fluoropolymer resin
Or crystal plane undetermined is orientated, and (purpose of thermal finalization is to disappear to carry out thermal finalization process when stretching
Except the internal stress produced in stretching so that the good stability of thin film, shrinkage factor is relatively low), draw through two-way
Molecule segment orientation, the degree of crystallinity stretched improve, and can significantly improve the hot strength of described thin film, stretching
Elastic modelling quantity, impact strength, tearing strength, improve tolerance to cold, the transparency, air-tightness, electrical insulating property
And glossiness etc.；According to simple tension, then can make perpendicular side along draw direction intensity increase
To intensity reduce.
In one embodiment of the invention, described step 2) specifically include:
Described mixture is processed into thin film by the mode using biaxial tension.
It should be noted that most important in order to improve the control of stretching quality, draft temperature and draw ratio,
Draw ratio refers to the length after stretching and the length ratio before stretching, and when draft temperature is higher, stretching is required
Tensile stress less, easily stretch, but the too high mobility making molecule segment of temperature aggravated, and makes to glue
Property deformation increase destroys orientation on the contrary；Otherwise, draft temperature is relatively low, then directional effect is preferable, but divides greatly
Subchain section mobility is poor, and required tensile stress is relatively big, is susceptible to skidding and unbalance stress and causes
Thickness deviation and width are unstable.
Also, it should be noted for different thin film, when the mode using biaxial tension prepares thin film,
The temperature in each stage and draw ratio the most difference, as a example by PET material, in described biaxial tension
In longitudinal stretching process, preheating section temperature can be 50-70 DEG C, and stretch section temperature can be 80-90 DEG C, cold
But sizing section temperature can be 30-60 DEG C, and draw ratio can be 3-3.5；Preheating section during cross directional stretch
Temperature can be 80-95 DEG C, and stretch section temperature can be 85-110 DEG C, and sizing section temperature can be
180-220 DEG C, cooling section temperature can be 30-60 DEG C, and draw ratio can be 3-4.
Being found through experiments, temperature and draw ratio to biaxial tension are controlled so that directional effect with
And molecule segment mobility is all preferable, the stretching quality of the thin film obtained is optimal.
Also, it should be noted after the mode through curtain coating or stretching makes acquisition thin film, in order to
Meet follow-up process requirements, the finished films obtained can be carried out single or double sided corona treatment,
The surface tension making thin film increases, by increasing capacitance it is possible to increase printing fastness, improves the adhesiveness of follow-up glue.
