Specific embodiment
With reference to the accompanying drawing, cold seal film provided by the invention and preparation method thereof is described in detail.
As shown in Figure 1, the preparation method of cold seal film provided in an embodiment of the present invention includes:
S100: providing a substrate, cross-linking printing ink is coated in the one side of substrate, so that the cross-linking printing of coated substrate
The surface of ink forms ink layer;
S200: ink protective layer is formed away from the surface of substrate in ink layer using evaporation process;
S300: patterned cold seal glue is formed away from the surface of ink layer in substrate.
Preparation process based on above-mentioned cold seal film it is found that in the preparation method for the cold seal film that this bright embodiment provides,
Cross-linking printing ink is coated by the one side in substrate, so that the surface of the cross-linking printing ink of the coated substrate forms oil
Layer of ink, then using evaporation process ink layer away from substrate surface formed ink protective layer, and due to vapor deposition when, be
It needs under vacuum conditions to heat material to be deposited, so that gasification deviates from the table of substrate to vapor deposition to ink layer
Face；As it can be seen that can also volatilize under the heating condition of vacuum environment clean, even if containing solvent in material to be deposited to protect
Card vapor deposition will be free from solvent in the ink protective layer on the surface of substrate to ink layer, and therefore, the embodiment of the present invention provides
Cold seal film preparation method it is prepared in cold seal film in, solvent is not contained in ink protective layer, so that cold seal is thin
Film saves a period of time, and material used in ink protective layer is hardly transferred to patterned cold seal glue, so that it is guaranteed that figure
The cold seal performance of the cold seal glue-line of case will not decline.
It should be noted that above-mentioned substrate can be vacuum aluminized film, ink layer is formed in the plating of vacuum aluminized film
Aluminium face；Patterned cold seal glue is coated on the vacuum aluminized film away from the surface in the face of aluminizing, and this makes it possible to pass through
The aluminium film isolation ink of vacuum aluminized film aluminized on face and patterned cold seal glue, prevent ink from passing through vacuum aluminum-coated thin
Film is seeped into patterned cold seal glue；That is, the preparation method of cold seal film provided in an embodiment of the present invention can adopt energy
With vacuum aluminized film, the protective effect to the ink of ink layer is played.
Illustratively, vacuum aluminized film is vacuum aluminum-coated bidirectional stretching polypropylene film or vacuum aluminum-coated poly- terephthaldehyde
Sour glycol ester film, naturally it is also possible to select other that can no longer list one by one herein as the vacuum aluminized film of substrate.
Further, in order to enable ink layer and patterned photoresist are preferably fitted in two different surfaces of substrate,
Before the one side of substrate coats cross-linking printing ink, the preparation method of above-mentioned cold seal film further include: to whole tables of substrate
Face is roughened, so that the contact area on the surface of ink layer and patterned cold seal glue and substrate is bigger, to protect
Demonstrate,prove the surface for being formed in substrate that ink layer and patterned cold seal glue can be even closer.
Optionally, the method for roughening treatment is varied, such as: sided corona treatment.When by the way of sided corona treatment into
When row roughening, sided corona treatment is that in substrate surface progress corona discharge, (high-frequency ac voltage is up to using high-frequency high voltage
5000-15000V/m2), and low temperature plasma is generated, so that substrate surface is rearranged surface of the stock molecular structure, produces
Raw more polar fractions, so that ink layer and patterned cold seal glue can preferably be formed in substrate surface.
Moreover, when substrate is vacuum aluminized film, after carrying out sided corona treatment to the surface of vacuum aluminized film, Vacuum Deposition
Not only roughness increases in the face of aluminizing of aluminium film, moreover, because thin for aluminium on the material in the face of aluminizing of vacuum aluminized film
Film, aluminum material after sided corona treatment occurs oxidation and is passivated, and forms closely knit aluminum oxide film, and this makes it possible into one
Step increases substrate for the isolation of ink layer ink.
In addition, used cross-linking printing ink is UV curable ink when above-described embodiment forms ink layer, this
Sample is coated to substrate surface when UV curable ink, it will be able to and using ultraviolet light UV curable ink is solidified, so that
The surface of substrate forms ink layer, the influence this also avoids heat cure to substrate.
In view of cold seal light oil reservoir is more sensitive to temperature in the cold seal film of the prior art, so that cold seal film can only be
It is saved under low temperature, this makes the preservation condition of cold seal film harsher；Based on this, as shown in Figures 2 and 3, can be used following
Two methods form ink film layer.
First method: as shown in Fig. 2, above-mentioned form oil away from the surface of substrate in ink layer using vacuum evaporation process
Black protective layer includes:
S210A: by UV-cured polyurethane acrylate vacuum evaporation coating vacuum evaporation to ink layer away from described
The surface of substrate；
S220A: the UV-cured polyurethane acrylate vacuum evaporation that ink layer is deposited away from the surface of substrate
Coating carries out ultraviolet light curing process, obtains the cross-linked polyurethane acylate film as ink protective layer.
From it is above-mentioned using evaporation process ink layer away from substrate surface formed ink protective layer detailed process it is found that
The material for forming ink protective layer is UV-cured polyurethane acrylate vacuum evaporation coating, and vapor deposition arrives ink layer surface
Afterwards, after solidification, it is formed by, table smooth as mirror surface as the cross-linked polyurethane acylate film of ink protective layer
Surface hardness is high, and adhesive force is good, can match in excellence or beauty with metal and relatively anti-, tests prove that, surface covering hardness is finally up to the left side 6h
The right side can prevent mirror surface from removing, therefore, cold seal film provided in an embodiment of the present invention can seal with the biggish article of density, and have
Good pressure resistance abrasive resistance, not cracky.Moreover, because what ink protective layer was combined using evaporation process and ultraviolet curing process
Mode is formed, and during evaporation process, most solvents have volatilized, after ink protective layer is formed, wherein almost
There is no dissolvent residual, it is therefore, above-mentioned to be subtracted in ink layer away from the surface of substrate formation ink protective layer using evaporation process
It is few even to prevent dissolvent residual, to be not in that cold seal glue envelope and ability decline after cold seal film saves a period of time
Problem.In addition, also solving cold seal light oil reservoir since cross-linked polyurethane acylate film is to temperature-insensitive and being protected as ink
When sheath, cold seal film needs the problem of saving under cryogenic.
And in order to improve the flexibility of cross-linked polyurethane acylate film, above-mentioned cross-linked polyurethane acylate film
Thickness limit is between 2nm-5nm, to avoid cross-linked polyurethane acylate film generated brittleness really up to the mark.
Second method: as shown in figure 3, above-mentioned form oil away from the surface of substrate in ink layer using vacuum evaporation process
Black protective layer can also make with the following method:
S210B: using vacuum evaporation process, and metal aluminium-vapour deposition to ink layer is deviated to the surface of substrate, forms aluminium film,
It is with a thickness of 5nm-7nm.
S220B: aluminium film is aoxidized using low-temperature plasma oxidation all-in-one machine, obtains the oxygen as ink protective layer
Change aluminium film.
When carrying out oxidation processes to metallic aluminium due to low-temperature plasma oxidation all-in-one machine, temperature is relatively low, reduces excessively high
Destruction of the temperature to ink layer and substrate layer, moreover, because being formed by ink protective layer is aluminium oxide after peroxidating
Film has relatively high wearability, and it is that therefore, also have by aoxidizing with a thickness of the aluminium film of 5nm-7nm
There is good flexibility.Simultaneously as using vacuum evaporation process when making aluminium film, and oxygen is being carried out to aluminium film
When changing processing, using plasma oxidation treatment process, it is not involved with any solvent in whole process, allows for institute in this way
Any dissolvent residual is not present in the aluminum oxide film as ink protective layer of formation, to guarantee that cold seal film saves one section
After time, sealing performance when cold seal is still good.In addition, also being solved cold since aluminum oxide film is to temperature-insensitive
When sealing light oil reservoir as ink protective layer, cold seal film needs the problem of saving under cryogenic.
It is further, above-mentioned that form patterned cold seal glue away from the surface of ink layer in substrate include: in substrate away from institute
The cold seal glue for stating the surface coated pattern of ink layer, obtains cold seal glue-line；Wherein, cold seal glue is according to 2g/m2-3g/m2Coating
Amount is applied to the surface that substrate deviates from ink layer.
It is to utilize the painting for increasing cold seal glue when in view of the technical issues of overcoming the embodiment of the present invention solved in the prior art
Cloth amount is come what is realized, and in general, after the coating weight for increasing cold seal glue in the prior art, the coating weight of cold seal glue is 4g/m2-
5g/m2, and the embodiment of the present invention due to used evaporation process make ink protective layer so that cold seal glue is according to 2g/m2-3g/m2
Coating weight be applied to substrate deviate from ink layer surface, after saving a period of time, the envelope and performance of cold seal glue are still good
It is good.
The embodiment of the invention also provides a kind of cold seal film, the preparation side of the cold seal film by adopting the above technical scheme
