The invention discloses a kind of adhesive sticker and preparation method thereof, the adhesive sticker is characterized in that, plane materiel is used as using polypropylene-polyethylene co-extrusion calendered film, relief printing plate flexographic ink prints adhesive and is bonded release base stock on plane materiel, the polypropylene-polyethylene co-extrusion calendered film is will to be extruded after polyethylene, polypropylene, polyethylene difference co-extrusion through three layers of T-shaped mould head, and then calendering formation is top layer polyethylene layer, intermediate layer polypropylene layer, the laminate of bottom polyethylene layer；The polyethylene is acrylic graft-modified LLDPE.The adhesive sticker of the present invention had both had the high property endured of polypropylene material or the flexibility for possessing polyethylene material.
Description
Technical field
The present invention relates to polymer film forming field, and in particular to a kind of adhesive sticker and preparation method thereof.
Background technology
In the past, adhesive material was used for TAG field, and generally it is for fabric with paper, plastic sheeting etc., and the back side applies
There is adhesive, to apply a kind of composite of the silicon bottom as release base stock, be made after the processing such as printing, being die cut.Due to making
Plane materiel is mostly paper or single composition plastic sheeting, and the former is non-watertight, and crease easily folding, and the latter is confined to plastic sheeting
Functional limitation, deflection is poor, intensity difference, cost are high.
The content of the invention
In view of the above-mentioned state of the art, the present invention provides a kind of adhesive sticker and preparation method thereof, and of the invention does not do
Glue is a kind of adhesive sticker of polypropylene-polyethylene material, and such a adhesive sticker had both had the high property endured of polypropylene material or possessed poly- second
The flexibility of alkene material.There is good ink adhesion in its surface, possess excellent processing characteristics so that back of the body patch thing possesses good
Good expressive force.
Specifically, the present invention provides a kind of adhesive sticker, using polypropylene-polyethylene co-extrusion calendered film as plane materiel, one on plane materiel
Face carries out relief printing plate flexographic ink printing, and another side coating adhesive is simultaneously bonded release base stock,
The polypropylene-polyethylene co-extrusion calendered film is will be T-shaped through three layers after polyethylene, polypropylene, polyethylene difference co-extrusion
Die head is extruded, and then calendering formation is top layer polyethylene layer, intermediate layer polypropylene layer, the laminate of bottom polyethylene layer；It is described
Polyethylene is LLDPE.
Wherein, the top layer polyethylene layer, intermediate layer polypropylene layer, the thickness of bottom polyethylene layer are respectively 17 μm, 50-
450μm、17μm；The thickness of gluing oxidant layer is 10 μm.
Release base stock can be for example conventional Ge Laxin base stocks.
Polyethylene layer uses the LLDPE of special modification, and adhesive material can be made to be applied without follow-up
Under conditions of cloth and directly carry out relief printing plate flexographic ink printing.It is strong to possess good combination simultaneously for adhesive sticker adhesive
Degree, is allowed to be bonded after PET not cull.
In addition, the intermediate layer polypropylene layer is using weight ratio as 5:It is prepared by 1 polypropylene and the mixture of colour masterbatch
Form.
The present invention also provides a kind of preparation method of adhesive sticker as described above, and it comprises the steps：
(1) by each raw material according to top layer polyethylene layer, intermediate layer polypropylene layer, bottom polyethylene layer the extruded machine of order
Go out respectively after melting extrusion through three layers of T-shaped mould coextrusion head；
(2) roll through 40 DEG C of stretcher rolls, cooling, corona；
(3) polyethylene layers carry out relief printing plate flexographic ink printings, be bonded after another polyethylene layer coating adhesive from
Type base stock.
Wherein, in step (1), 17 μm of 220 DEG C of extrusion temperature, the thickness of top layer polyethylene；
Middle 250 DEG C of layer polypropylene extrusion temperature, 50-450；
220 DEG C of bottom polyethylene extrusion temperature, 17 μm of thickness.
In addition, the extrusion temperature of three layers of T-shaped mould head is 250 DEG C.
For the adhesive sticker of the present invention compared with traditional adhesive sticker, the plane materiel that adhesive sticker of the present invention uses is to use the poly- second of polypropylene
Alkene co-extrusion calendered film, such a material makes polypropylene be layered co-extrusion calendering formation after die head is extruded with polyethylene, post-treated to add
Work is made, and has both possessed polyethylene flexibility, excellent processing characteristics it is hereby achieved that a kind of, but also with polyacrylic intensity and
The adhesive sticker product of deflection；And the present invention can make adhesive material under conditions of without follow-up coating and directly enter
Row relief printing plate flexographic ink prints.Possess good bond strength simultaneously for adhesive sticker adhesive, be allowed to be bonded not residual after PET
Glue..

Embodiment
Technical solution of the present invention is discussed in detail below in conjunction with the accompanying drawings, but the present invention is not limited to this.
Fig. 1 is the structural representation of adhesive sticker of the present invention.As shown in figure 1, the adhesive sticker of the present invention, possesses plane materiel 4, gluing
Agent 5, release base stock 6.
Plane materiel 4 includes：Top layer polyethylene layer 1, intermediate layer polypropylene layer 2, bottom polyethylene layer 3.
The preparation method of the adhesive sticker of the present invention, is respectively to gather top layer polyethylene layer 1, intermediate layer polypropylene layer 2, bottom
The respective raw material of pvdf layer 3 is melted and then made after being extruded in the lump in three layers of T-shaped mould head after calendering respectively by extruder
Polypropylene-polyethylene calendered film is obtained, and relief printing plate flexographic ink is carried out as plane materiel 4 and then through cooling, corona, a face
Printing, another face coating adhesive 5 are simultaneously bonded release base stock 6 and are made.
Specifically, it is 5 by film level polyethylene, weight ratio:1 polypropylene and colour masterbatch, the extruded machine of film level polyethylene
Extrusion, wherein 220 DEG C of the extrusion temperature of the polyethylene of top layer polyethylene layer, 17 μm of thickness, weight ratio are 5:1 polypropylene and face
250 DEG C of the extrusion temperature of color masterbatch, 50-400 μm of thickness；220 DEG C of extrusion temperature, the thickness of the polyethylene of layer polyethylene layer
17μm.Extruded by three layers of T-shaped mould head, extrusion temperature is 250 DEG C, 40 degree of stretcher roll, is cooled down through calendering, corona, winding etc.
Plane materiel is made in technical process.Then facestock is cut again, a face relief printing plate flexographic ink printing, another main coating glue
Glutinous agent thickness is 10 μm, is bonded the adhesive sticker that the present invention is made in release base stock.
Adhesive sticker can directly carry out the printing of UV relief printing plates and soft version without coating, using 3M600 adhesive tape tests without falling
Black phenomenon.Specific method of testing is that 3M600 adhesive tapes pull out to 20cm is smooth to be affixed on tested new label printing face, and finger comes energetically
Go back to 180 degree directions before rolling 5 times backward and quickly tear adhesive tape, it is desirable to which printing-ink is intact, and oil-free Motuo falls, noresidue on adhesive tape
Ink.
