The content of the invention
Present invention mainly solves technical problem be, there is provided it is a kind of to prepare film for high speed fluid filler sealing strip,
Meet peel strength requirement meanwhile, it is capable to be used in enterprising exercise of high speed fluid filler.
The technical solution adopted for the present invention to solve the technical problems is：A kind of system for high speed fluid filler sealing strip
Standby film, including the first co-extrusion film layer, film PE layers and the second co-extrusion film layer bonded successively；The thickness for preparing film is 70-
100um.Its thickness of the film so produced is still identical with former thickness, but so made of inside film without glue,
The materials such as solvent, reduce VOC volatilization, reduce pollution, improve environment.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the invention, the first co-extrusion film layer
It is identical with 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 layer blown film co-extrusions obtain.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the 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 invention, the first adhesive layer with
Resin in second adhesive layer is by adding two tertiary fourths of initiator 2,5- dimethyl -2,5- in HDPE and PA6 extruding pelletizations
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 invention, co-extrusion granulation
HDPE and PA6 mass ratio is：15%HDPE, 85%PA6.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the invention, the first co-extrusion film layer
Thickness with the second co-extrusion film layer is 30-40um, and the film PE thickness degree is 10-20um.
As a kind of further improvement for preparing film for high speed fluid filler sealing strip of the invention, material used in adhesive layer
Matter is the polymer of PE grafted maleic anhydrides.
The method for preparing film for high speed fluid filler sealing strip is prepared, is comprised the technical steps that：Pass through two nine
Layer coextrusion film blowing equipment blows out two panels 30-40um co-extrusion film respectively, then will using 10-20um film PE by squeezing multiple equipment
Two panels 30-40um co-extrusion film is bonded together.Using co-extrusion equipment blowout 30-40um co-extrusion film, material include PE,
TIE, PA or EVOH barrier material, because doing so thin product, it is necessary to be realized by way of increasing linear velocity, linear speed
After degree improves (blown film linear velocity before is 30m/min, present blown film 60-70m/min), the orientation behavior increase of molecule,
So that molecular orientation arranges, the mechanical strength of film is added, also reduces the elongation of film；The technique can only be related to PE
Bonding between PE, so relatively easily solve the problems, such as peel strength, and also without chemicals such as solvent glue
Matter, the contribution also having had to environmental protection.The linear velocity 100m/min of film, carried plus present blown film (thickness is small) linear velocity
It is high 2 times or so, therefore overall production efficiency improves 3 times incessantly.
The further improvements in methods for preparing film for high speed fluid filler sealing strip, adhesive layer are prepared as the present invention
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；Take 0.5 part of MAH added after being dissolved in 100mL acetone 0.1 part of 2,5- dimethyl -2,5- di-t-butyls peroxide oneself
Alkane forms 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 the area of extruder 1~7 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 is 195 DEG C.Reaction mechanism in granulation process is as follows：
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 hydrogen atom that the primary group of free radicals is grabbed on HDPE main chains afterwards, macromolecular radical PH-HD is formed, sees formula (3), macromolecular
Free radical PH-HD forms PE-HD-g-MAH with the hydrogen atom in MAH double bonds, sees formula (4)；PE-HD-g-MAH anhydride group
Group and PA6 Amino End Group condensation reaction form HDPE-g-MAH-g-PA6, see formula (5) and (6).
PA6 and HDPE blend is with HDPE content increase, and its peel strength is fallen after rising, when HDPE content is
When 20%~25%, peel strength highest, because initiator 2, heated point of 5- dimethyl -2,5- di-t-butyls peroxyhexane
Solution produces primary group of free radicals, after the free radical captures a HDPE hydrogen atom, generates macromolecular radical PH-HD, so
Macromolecular radical PH-HD and MAH form PE-HD-g-MAH afterwards, then PE-HD-g-MAH anhydride group can and PA6
Amino End Group condensation reaction occurs, form PA6-g-MAH-g-HDPE graft polymers.The graft polymers enhances scattered
Water ratio limit intensity between phase HDPE and continuous phase PA6, distributions of the dispersed phase HDPE in matrix PA6 is refined.By
When external force acts on, due to the water ratio limit effect between dispersed phase HDPE and continuous phase PA6, HDPE particles are difficult from continuous phase
Spun off in PA6, therefore its peel strength is improved.But excessive HDPE addition can make caused PE-HD-g-MAH
Quantity is not enough, so as to cause the compatibility poor between dispersed phase HDPE and continuous phase PA6 so that the stripping of co-mixing system is strong
Degree declines.
With the increase of HDPE contents, elevated trend after first reducing is presented in the tensile strength of PA6 and HDPE blend,
When HDPE contents are %40, its 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, when HDPE contents are 30%, its elongation at break reaches maximum.It is permanent when being added due to MAH
Fixed, when it is 10% to add HDPE contents, its amount is less, therefore the macromolecular radical PH-HD as caused by triggering initiator
Fewer, therefore the PE-HD-g-MAH quantity generated is fewer, PA6 and HDPE compatibility are poor so that tensile strength and disconnected
Split elongation decline.With HDPE content increase, it triggers generation macromolecular radical PH-HD relatively more by initiator,
In melt blending, macromolecular radical PH-HD and MAH fully react, and form PE-HD-g-MAH grafts, improve
Compatibility between PA6 and HDPE, and promote the scattered of HDPE, it is suppressed that the aggregation of dispersed phase particles；And PE-HD-g-
MAH anhydride group and PA6 Amino End Group occur condensation reaction and form PH-HD-g-PA6 graft polymers, enhance dispersed phase
Water ratio limit power between HDPE and continuous phase PA6, it is set not allow when being acted on by external force between the molecule segment of co-mixing system
Easily enter line slip, the external force increase needed for drawing process；On the other hand, dispersed phase HDPE can be as matrix PA6 stress
Centrostigma, surrounding matrix is easily induced when being acted on by external force produces crazing-shear band and absorb energy, therefore its tensile strength
Increase with elongation at break.In order to take into account low elongation at break and high-peeling strength, select HDPE contents weight ratio for 15% when
For preferred scheme of the present invention.
Beneficial effects of the present invention have：
1st, its thickness of the film produced is still identical with former thickness, but without glue, solvent inside manufactured film
Deng material, reduce VOC volatilization, reduce pollution, improve environment.
2nd, 30-40um co-extrusion film is blown out using co-extrusion equipment, linear velocity improves, and the orientation behavior increase of molecule, makes
Obtain molecule to align, the mechanical strength of film increases more than 50Mpa, the elongation at break of film from original 35Mpa
Less than 150% is fallen below from original 235%, cuttability can be used for well high speed fluid filler.
3rd, blown film linear velocity before is 30m/min, present blown film 60-70m/min；The linear velocity 100m/min of film,
Therefore overall production efficiency improves 3 times incessantly.
4th, the technique can only be related to the bonding between PE and PE, so relatively easily solving asking for peel strength
Topic, the peel strength of MPM bars do not have in 3N/7.5mm, the film peel strength of the technique productions in more than 5N/7.5mm yet
