Meet peel strength to require meanwhile, it is capable to use in the enterprising enforcement of high speed fluid filler.
The technical solution adopted by the present invention to solve the technical problems is: a kind of system for high speed fluid filler sealing strip
Standby film, including PE layers of the first co-extrusion film layer, lamination successively bonding and the second co-extrusion film layer；It is described prepare film with a thickness of 70-
100um.Its thickness of the film produced in this way is still identical as pervious film thickness, but in this way made of inside film without glue,
The materials such as solvent reduce the volatilization of VOC, reduce pollution, improve environment.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, the first co-extrusion film layer
It is identical as the second co-extrusion film layer, including set gradually the first PE layers, the first adhesive layer, barrier resin layers, the second adhesive layer and
2nd PE layers of blown film co-extrusion obtain.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, in barrier resin layers
Resin used is PA or EVOH.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, the first adhesive layer and
Resin in second adhesive layer is by the way that the tertiary fourth of initiator 2,5- dimethyl -2,5- two is added in HDPE and PA6 extruding pelletization
HDPE-g-MAH-g-PA6 made of base peroxyhexane.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, what co-extrusion was granulated
The mass ratio of HDPE and PA6 are as follows: 15%HDPE, 85%PA6.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, the first co-extrusion film layer
Thickness with the second co-extrusion film layer is 30-40um, and described lamination PE layers with a thickness of 10-20um.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the present invention, material used in adhesive layer
Matter is the polymer of PE grafted maleic anhydride.
Preparation is used for the method for preparing film of high speed fluid filler sealing strip, comprises the technical steps that: by two nine
Layer coextrusion film blowing equipment blows out the co-extrusion film of two panels 30-40um respectively, then will using the lamination PE of 10-20um by squeezing multiple equipment
The co-extrusion film of two panels 30-40um is bonded together.Using co-extrusion equipment blowout 30-40um co-extrusion film, material include PE,
TIE, PA or EVOH barrier material need to realize by way of increasing linear velocity, linear speed because doing so thin product
After degree improves (blown film linear velocity before is 30m/min, present blown film 60-70m/min), the orientation behavior of molecule increases,
So that molecular orientation arranges, the mechanical strength of film is increased, the elongation of film is also reduced；The technique can only be related to PE
Bonding between PE, so being relatively easy to solve the problems, such as peel strength, and also without chemicals such as solvent glue
Matter, the contribution also having had to protection environment.The linear velocity 100m/min of lamination, in addition present blown film (film thickness is small) linear velocity mentions
It is 2 times or so high, therefore whole production efficiency improves 3 times incessantly.
The further improvements in methods for preparing film of high speed fluid filler sealing strip, adhesive layer are used for as present invention preparation
In resin HDPE-g-MAH-g-PA6 preparation process it is as follows: after PA6 and HDPE is dried 24 hours in 80 DEG C of baking oven
It is cooled to room temperature；Be added after taking 0.5 part of MAH to be dissolved in 100mL acetone 0.1 part of 2,5- dimethyl -2,5- di-t-butyl peroxide oneself
Alkane formed acetone soln, by mass ratio account for 85% PA6 and mass ratio account for 15% HDPE mix after be separately added into acetone soln,
With parallel double-screw machine extruding pelletization, screw speed 60r/min, the temperature in 1st~7 area of extruder be respectively set to 185 DEG C,
200 DEG C, 210 DEG C, 220 DEG C, 220 DEG C, 215 DEG C, 205 DEG C, head temperature are 195 DEG C.The reaction mechanism is as follows in granulation process:
2,5- dimethyl -2,5- di-t-butyl peroxyhexanes (structural formula is shown in formula (1)) are cleaved into primary group of free radicals first, see formula (2), so
The primary group of free radicals grabs the hydrogen atom on HDPE main chain afterwards, forms macromolecular radical PH-HD, sees formula (3), macromolecular
A hydrogen atom on free radical PH-HD and MAH double bond forms PE-HD-g-MAH, sees formula (4)；The anhydride group of PE-HD-g-MAH
Group and the Amino End Group condensation reaction of PA6 form HDPE-g-MAH-g-PA6, see formula (5) and (6).
The blend of PA6 and HDPE increases with the content of HDPE, and peel strength is fallen after rising, when the content of HDPE is
When 20%~25%, peel strength highest, this is because initiator 2, heated point of 5- dimethyl -2,5- di-t-butyl peroxyhexane
Solution generates primary group of free radicals and produces macromolecular radical PH-HD, so after the free radical captures a hydrogen atom of HDPE
Macromolecular radical PH-HD and MAH form PE-HD-g-MAH afterwards, then the anhydride group of PE-HD-g-MAH can and PA6
Amino End Group occur condensation reaction, form the graft polymers of PA6-g-MAH-g-HDPE.The graft polymers enhances dispersion
Water ratio limit intensity between phase HDPE and continuous phase PA6 has refined distribution of the dispersed phase HDPE in matrix PA6.By
When external force, due to the water ratio limit effect between dispersed phase HDPE and continuous phase PA6, HDPE particle is difficult from continuous phase
It is detached in PA6, therefore its peel strength is improved.But the addition of excessive HDPE can make the PE-HD-g-MAH generated
Quantity is not enough, so that the compatibility poor between dispersed phase HDPE and continuous phase PA6 is caused, so that the removing of co-mixing system is strong
Degree decline.
With the increase of HDPE content, raised trend after first reducing is presented in the tensile strength of the blend of PA6 and HDPE,
When HDPE content is %40, tensile strength reaches 54.01MPa.The elongation at break of blend is in first to reduce to rise afterwards to connect
The variation tendency declined again, HDPE content be 30% when, elongation at break reaches maximum value.It is permanent when being added due to MAH
Fixed, when it is 10% that HDPE content, which is added, amount is less, therefore causes the macromolecular radical PH-HD generated by initiator
The compatibility of PE-HD-g-MAH small number that is fewer, therefore generating, PA6 and HDPE is poor, so that tensile strength and disconnected
Split elongation decline.It is relatively more by initiator initiation generation macromolecular radical PH-HD as the content of HDPE increases,
In melt blending, macromolecular radical PH-HD and MAH sufficiently react, and form PE-HD-g-MAH graft, improve
Compatibility between PA6 and HDPE, and promote the dispersion of HDPE, it is suppressed that the aggregation of dispersed phase particles；And PE-HD-g-
The anhydride group of MAH and the Amino End Group of PA6 occur condensation reaction and form PH-HD-g-PA6 graft polymer, enhance dispersed phase
Water ratio limit power between HDPE and continuous phase PA6, makes it when by external force, does not allow between the molecule segment of co-mixing system
It is easily slid, external force needed for drawing process increases；On the other hand, dispersed phase HDPE can be used as the stress of matrix PA6
Centrostigma, easy induction surrounding matrix generation crazing-shear band absorption energy when by external force, therefore its tensile strength
Increase with elongation at break.Low elongation at break and high-peeling strength in order to balance, when to select HDPE content weight ratio be 15%
For the preferred solution of the invention.
The beneficial effects of the present invention are as follows:
1, its thickness of the film produced is still identical as pervious film thickness, but does not have glue, solvent inside manufactured film
Equal materials, reduce the volatilization of VOC, reduce pollution, improve environment.
2, using the co-extrusion film of co-extrusion equipment blowout 30-40um, linear velocity is improved, and the orientation behavior of molecule increases, and is made
It obtains molecule to align, the mechanical strength of film increases 50Mpa or more, the elongation at break of film from original 35Mpa
150% is fallen below hereinafter, cuttability can be used for well high speed fluid filler from original 235%.
3, blown film linear velocity before is 30m/min, present blown film 60-70m/min；The linear velocity 100m/min of lamination,
Therefore whole production efficiency improves 3 times incessantly.
4, the technique can only be related to the bonding between PE and PE, so being relatively easy to solve asking for peel strength
Topic, in 3N/7.5mm, the film stripping intensity of technique production does not have the peel strength of MPM item in 5N/7.5mm or more, and yet
The chemical substances such as solvent glue, the contribution also having had to protection environment.
