Abstract
Low scratch resistant acrylic protective film, including PET base material layer, primary coat liquid layer, acrylate glue water layer and release film are glued the utility model discloses a kind of；The primary coat liquid layer is formed and being coated with primary coat liquid on the corona surface in PET base material layer, and the acrylate glue water layer is formed and being coated with acrylic acid glue on primary coat liquid layer；The layer upper surface of the release film is covered on acrylate glue water layer.The low of the utility model glues scratch resistant acrylic protective film, and scratch resistant performance is good, can not be die cut powder.
Description
Technical field
The utility model relates to protective film fields, and in particular to one kind is low to glue scratch resistant acrylic protective film.
Background technique
Protective film rises in six the seventies of last century in American-European some developed countries, by continuing to develop, now by
It is widely used in the industries such as machinery, instrument, electronics, ship, construction material, automobile manufacture.China is in early eighties mid-term
It rises, by continuous developmental research, also achieves significant progress, protective film is a branch of pressure sensitive adhesive product.Broad sense
On protective film be in recent ten years with the rise of touch-control electron-like industry, and building, furniture industry get over product appearance
Carry out higher requirement, protective film comes into being, and tracing to its source is derived by traditional adhesive tape, most common on the market at present
Protective film be acrylic protective film, and dosage it is maximum for electronics be die cut industry used in single-layer acrylic protective film,
It is widely used in electronics industry especially mobile phone industry, it is interim to turn mainly as the auxiliary material of electronic material cross cutting processing procedure
It moves and fixes, be posted waste discharge and the screen protection of electronic digital product, shipment turnover.
Low viscous single layer protection film currently on the market is easy to happen punching picking since glue cohesive force is poor more crisp
Problem.For cross cutting industry, with making rapid progress for dise knife die-cutting process, arranges in pairs or groups in electronic material and application above receives
Very big limitation.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of scratch resistant performance is good, it can not be die cut the low of powder and glue scratch resistant Asia
Gram force protective film.
In order to solve the above-mentioned technical problem, the utility model, which provides, a kind of low glues scratch resistant acrylic protective film, including PET
Substrate layer, primary coat liquid layer, acrylate glue water layer and release film；The primary coat liquid layer is by the corona surface of PET base material layer
It is coated with primary coat liquid and is formed, the acrylate glue water layer is formed and being coated with acrylic acid glue on primary coat liquid layer；It is described
Release film is covered on acrylate glue water layer.
In a preferable embodiment of the utility model, the primary coat liquid layer is covered on the corona of PET base material layer
On face.The corona surface roughness of PET is higher, is conducive to the operation of subsequent linging masking liquid, so that the bonding of primary coat liquid and PET base material
It is even closer.
In a preferable embodiment of the utility model, the PET base material layer is transparent PET base material layer.
In a preferable embodiment of the utility model, the release film is transparent single silicon release film.
In a preferable embodiment of the utility model, the primary coat liquid layer with a thickness of 1 μm.
In a preferable embodiment of the utility model, the glue layer with a thickness of 10 μm.
The utility model has the beneficial effects that:
1, the protective film of the utility model, using PET as substrate, with excellent physical mechanical property, rub resistance
Can be good, so that protective film obtains preferable toughness, stiffness and scratch resistant performance.
2, the protective film of the utility model increases primary coat liquid layer in PET base material layer, increases PET base material layer and third
The adhesive force of olefin(e) acid glue layer, from thus greatly reducing protective film in cross cutting the phenomenon that powder.
3, the protective film of the utility model, cleanliness is excellent, glue surface planarization is good, has the high grade of transparency；Adhesion strength is through time-varying
Change small, easily peelable, no residue glue；Shock resistance, oil resistant, weatherability are good.
Detailed description of the invention
Fig. 1 is the low schematic diagram for gluing scratch resistant acrylic protective film of the utility model；
Wherein: 1, PET base material layer；2, primary coat liquid layer；3, acrylate glue water layer；4, release film.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Referring to Figure 1, low scratch resistant acrylic protective film, including PET base material layer 1, bottom are glued the utility model discloses a kind of
Apply liquid layer 2, acrylate glue water layer 3 and release film 4；The primary coat liquid layer 2 is by applying in any one side of PET base material layer 1
Cloth primary coat liquid and formed, the acrylate glue water layer 3 be by primary coat liquid layer 2 be coated with acrylic acid glue and formed；It is described
Release film 4 is covered on acrylate glue water layer 3.
The protective film of the utility model, using PET as substrate, with excellent physical mechanical property, crocking resistance
It is good, so that protective film obtains preferable toughness, stiffness and scratch resistant performance.
The protective film of the utility model increases primary coat liquid layer 2 in PET base material layer 1, increases PET base material layer 1 and third
The adhesive force of olefin(e) acid glue layer 3, from thus greatly reducing protective film in cross cutting the phenomenon that powder.
Preferably, primary coat liquid layer 2 is covered on the corona surface of PET base material layer 1.The corona surface roughness of PET is higher, favorably
In the operation of subsequent linging masking liquid, so that the bonding of primary coat liquid and PET base material is even closer.
In the present embodiment, PET base material layer 1 is transparent PET base material layer 1, and release film 4 is transparent single silicon release film 4, thus
So that obtained protective film cleanliness is excellent, and there is the high grade of transparency.
In the present embodiment, primary coat liquid layer 2 with a thickness of 1 μm, glue layer with a thickness of 10 μm.
The protective film of the present embodiment the preparation method is as follows:
It is coated with one layer of primary coat liquid first on the corona surface of transparent PET and obtains primary coat liquid layer 2 after baking and curing, receives
Volume is stand-by；Then acrylic acid glue of the coating with calculated viscosity on primary coat liquid layer 2, obtains acrylic acid after baking and curing
Glue layer 3；The layer upper surface of transparent single silicon release film 4 is fitted on acrylate glue water layer 3 again, is wound into semi-finished product.Then, will
Semi-finished product send to 50 DEG C of curing chamber and cure 72 hours, are cooled to room temperature to get the protective film of the present embodiment is arrived.The protective film is peelable
From release film 4, winding is stand-by in single layer structure.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model
Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model
It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
