Description
Technical field
The utility model relates to release technical field of membrane more particularly to a kind of anti-scratch type release films.
Background technique
Release film refers to that film surface can have the film of differentiation, and release film contacts under limited conditions with specific material
Do not have viscosity or slight viscosity afterwards.It can be divided by different substrate materials：It is PE release film, PET release film, OPP release film, compound
Release film（I.e. substrate is that have two or more material to be combined）Deng.
PET release film is also PET silicon oil membrane, exactly one layer of silicone oil is coated on the surface of PET film, to reduce PET film
The adhesive force on surface achievees the effect that release.PET release film should be packed extensively, be printed, silk-screen, bat printing, engraved plate, is thin
Membrane switch, flexible circuitry, insulated product, wiring board, laser anti-counterfeit, fitting, electronics, sealing material use film, reflectorized material, waterproof
Material, medicine（Cream medicinal paper）, sanitary paper, adhesive article, cross cutting stamp processing etc. industry fields.
Release film in the prior art, on the surface for covering metal material, pcb board and other oxidizable materials
When, since the anti-scratch performance of these release films is bad, so that these products are easy to be scraped off, do not have the effect of protection.
Therefore, the existing technology needs to be improved and developed.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of anti-scratch type release films, it is intended to
Solve the problems, such as that the anti-scratch performance of release film in the prior art is bad.
The technical solution of the utility model is as follows：
A kind of anti-scratch type release film, wherein the anti-scratch type release film includes:
From top to bottom it is sequentially overlapped release film layer together, organic silica gel film layer, hardening scratch-resistant layer, pressure-sensitive adhesive layer and double
To oriented polypropylene film layer；
It is described hardening scratch-resistant layer with a thickness of 1 μm -3 μm；
The pressure-sensitive adhesive layer is bonded by the gluey arrangement of point and the upper surface of biaxially oriented polypropylene film layer.
Preferably, the anti-scratch type release film, wherein the release film layer is PET release film layer.
Preferably, the anti-scratch type release film, wherein the release film layer with a thickness of 50 μm -100 μm.
Preferably, the anti-scratch type release film, wherein the organic silica gel film layer with a thickness of 20 μm -50 μm.
Preferably, the anti-scratch type release film, wherein the biaxially oriented polypropylene film layer with a thickness of 30 μm of -60 μ
m。
Compared with prior art, anti-scratch type release film provided by the utility model, including：From top to bottom it is sequentially overlapped
Release film layer, organic silica gel film layer, hardening scratch-resistant layer, pressure-sensitive adhesive layer and biaxially oriented polypropylene film layer together；The hardening
Scratch-resistant layer with a thickness of 1 μm -3 μm；The upper surface that the pressure-sensitive adhesive layer passes through point gluey arrangement and biaxially oriented polypropylene film layer
Bonding effectively protects so that the release film has good anti-scratch performance by label apparatus, meanwhile, organosilicon glue film has
Good exhaust performance improves release film adhesiveness.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the anti-scratch type release film preferred embodiment in the utility model.
Specific embodiment
The utility model provides a kind of anti-scratch type release film, to make the purpose of this utility model, technical solution and effect more
Add clear, clear, referring to the drawings and gives an actual example the utility model is further described.It should be appreciated that this place is retouched
The specific embodiment stated is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, a kind of anti-scratch type release film provided by the embodiment of the utility model, including:From top to bottom successively fold
Release film layer 10, organic silica gel film layer 20, hardening scratch-resistant layer 30, pressure-sensitive adhesive layer 40 and the biaxially oriented polypropylene film being added together
Layer 50；It is described hardening scratch-resistant layer 30 with a thickness of 1 μm -3 μm；The pressure-sensitive adhesive layer 40 is poly- by the gluey arrangement of point and biaxial tension
The upper surface of propylene film layer 50 bonds.
When it is implemented, passing through release film layer 10, hardening scratch-resistant layer 30 and 50 three-layer thin-film of biaxially oriented polypropylene film layer
Effect, effectively raise the anti-scratch performance of the release film, improve release film to by the protective effect of label apparatus.In addition,
Since organosilicon glue film has good exhaust performance, so that bubble will not be generated in the release film, it is viscous to effectively raise it
Conjunction property.
In the further preferred embodiment of the utility model, the release film layer 10 is PET release film layer.
In the further preferred embodiment of the utility model, the release film layer 10 with a thickness of 50 μm -100 μm.
In the further preferred embodiment of the utility model, the organic silica gel film layer 20 with a thickness of 20 μm -50 μm.
In the further preferred embodiment of the utility model, the biaxially oriented polypropylene film layer 50 with a thickness of 30 μm of -60 μ
m。
In conclusion anti-scratch type release film provided by the utility model, including：It is from top to bottom sequentially overlapped together
Release film layer, organic silica gel film layer, hardening scratch-resistant layer, pressure-sensitive adhesive layer and biaxially oriented polypropylene film layer；The hardening scratch-resistant layer
With a thickness of 1 μm -3 μm；The pressure-sensitive adhesive layer is bonded by the gluey arrangement of point and the upper surface of biaxially oriented polypropylene film layer, is made
Obtaining the release film has good anti-scratch performance, effectively protects by label apparatus, meanwhile, organosilicon glue film has good row
Gas performance improves release film adhesiveness.
It should be understood that the application of the utility model is not limited to above-mentioned citing, those of ordinary skill in the art are come
It says, it can be modified or changed according to the above description, and all these modifications and variations all should belong to the appended power of the utility model
The protection scope that benefit requires.
