Description
Technical field
The present invention relates to a kind of for being generated by microplissement (Mikrofaltung) especially in the layer of UV curable
The method of surface effect and a kind of device being used to manufacture this layer and the article obtained according to the present invention.
Another aspect of the present invention relates to provide that High energy particles Radiation (energiereiche can be passed through
Partikelstrahlung), such as coating fluid of UV radiation curings, can be using handling according to the method for the present invention.
Background technology
The solidification that polymerizable organic coating is radiated by means of High energy particles Radiation, such as UV has been certainly work many years ago very much
The technique grasped in industry.Especially it is known that can be how by selecting suitable application system to generate matt or gloss table
Face.
Within the scope of this invention, the explanation of the gloss on the surface painted or painted corresponds to DIN 67 530 or ISO
2813, wherein the explanation of gloss unit is carried out when observing corresponding surface with 60 ° of angle.As the surface of high glaze, phase
Refer to the surface with the glossiness between 70 to 100GU (GU=Glanzeinheiten, gloss units) with answering, as
Satin lustre surface, the glossiness having is 45 between 70GU, and as satin face matt surface, the glossiness having is 20
To between 45GU.The glossiness that matt surface has is less than 20GU.
However, difficult point is using an application system while to generate the region of matt and gloss, example
Such as, to indicate the specific functional area on surface.It is also known that the such surface of production, should have determining structure
Or specific sense of touch, i.e. special tactile impression.However, for the effect, being generated simultaneously using same application system is had not
The region of same vision or structural form can only be realized under the cost of very high equipment at present.
Different tactiles is generated using same application system and/or visual signature, such as matt/luster effect can be different
Mode realize.One simple feasible program is coated on the different precondition substrate in part.This example is substrate
UV solidified paints, the substrate are pre-processed using the mimeograph paint of wetability difference or special printing ink in advance.In such case
Under, the subsequent coated on pretreated region generates the separation of coating and thus generates matt surface.
The effect is well-known with " chemical embossing " in Asia.In Europe, this method is referred to as " Drip-Off-
Lackierung (drippage japanning) ".
It is known to be carried out the different processing in follow-up part on uniform film by means of template.
It does not expect usually but is very familiar with for the skilled person in the application, depend in the surface of matt japanning
Also there is the variation of matt degree in thickness.Thus, for example matting agent particles are partly no longer present in table in thicker enamelled coating
At face, the matt degree that thus film shows in this region is lower.The effect can also targetedly be used.
It equally it is known that such method, coating after completing coating by acting on existing coated film wherein
Surface carry out matt.In the simplest case, this can be realized by etching or sandblasting.It equally, herein can be by means of template
Pattern is generated on the surface.
If realizing that (part) generates roughness by means of high-energy radiation, similar effect can also be in the coating of still fluid
In generate before curing.
Therefore, 10 2,006 042 063 A1 of German patent application DE disclose a kind of glossiness for adjusting surface
Method, the surface can by with can the coating of paint of UV or electronic beam curing obtain.Here, making the monochromatic UV of shortwave first
Radiation effects is on coated on the coating on substrate so that only occurs polymerizeing in the surface layer of coating and be crosslinked.In second step
In, on the electromagnetic radiation to coating that makes another more long wavelength so that in the whole thickness for the coating that crosslinking appears in coating
And layer correspondingly cures.In this way so that by thus inducing the crosslinking of generation to cause microplissement in surface layer,
It is fixed by the subsequent cure of entire layer.It can be in this way by means of an application system by suitably selected cure parameter
Generate high glaze and matt surface.
Therefore, within the scope of this invention, following phenomenon is interpreted as microplissement：The surface layer of the coating fluid of coating exists
The layer of skin shape is solidified into the first step, it means that layer has by the harder or more tough and tensile part of near surface.Due to solid
Contraction when change, surface layer are folded in solidification.Thus there is certain structure, cause at least in the subregion of coating surface
Change in the presence of the part for applying thickness so that thickness fluctuation is at least in the micron range of one digit number.Especially surface layer is with fold
Form exists.In second step, the coating fluid of coating is made to cure in whole volume.
As the source of monochromatic radiation, microplissement can be caused by the crosslinking on surface layer, use excimer radiation herein
Device.Wavelength 172 or the monochromatic radiation of 222nm are especially used herein.
However, the shortcomings that excimer radiation device (Excimer-Strahlen) is used for microplissement is, in order to ensure
Even matt, it is necessary to be irradiated under inert gas atmosphere, because oxygen known to the coating for free-radical curable presses down
System negatively affects the desired reaction at surface.Thus, for example 2007/068322 A1 of international patent application WO are disclosed
A kind of device wherein, makes irradiation condition keep steady it is suitable for executing the method for the microplissement of the paint for UV curable
It is fixed.For this purpose, so designing radiation source, that is, ensure stable inert gas atmosphere, and inert gas is simultaneously for cooling radiation
Device so that extend the service life of excimer radiation device.
2418091 A1 of European patent application EP disclose the another improvement project of the above method.It is disclosed that one kind
Method wherein only occurring microplissement in the subregion on paint surface, and obtains smooth in other regions on paint surface
Surface.For this purpose, paint surface is only loaded in the subregion accordingly selected for the shortwave electromagnetism spoke needed for microplissement
It penetrates, radiation source is equipped with template or mask thus so that the desired only part of exposure on surface only occurs.By this method,
Obtain such coating comprising at least one region on matt or microplissement surface and with smooth surface
At least one region, wherein the thickness in these regions does not have difference or only insignificantly different.
Equally, it for the method disclosed in 2418019 A1 of EP, is radiated using excimer radiation device to generate miniature pleat
Wrinkle.
Low penetration depth of the mechanism of microplissement disclosed in patent application mentioned above based on radiation and because
This is received using the combination of the characteristic of the system of free-radical curable influenced by near surface with undergoing solidification during polymerisation
Contracting.The film swum on the still coating material of liquid, the fold due to cure shrinkage are generated by both effects.
In the second curing schedule subsequently carried out, make still liquid intermediate region equally solidification and it is thin with the surface of substrate and fold
Film connects.
Therefore, the matt surface for generating microplissement or the table with special optical effect or certain tactile impression
The known method in face generally has the drawback that the structure in order to generate microplissement must necessarily use excimer radiation
Device.Even if when also can be used the light up to 300nm to be used to generate microplissement as illustrated in 2418019 A1 of EP,
Still monochromatic source is needed always, is additionally different from the second light source needed to make coating fully be fully cured.It is former
Because being, the radiation of excimer radiation device is significantly absorbed in coating solution or paint, to the solidification of thin film, example only occur
If cured thickness is only several microns.Therefore, thicker compared with the penetrating depth corresponding to laser emission, if skin of paint is whole
It is thicker, in order to make skin of paint cure in whole thickness using the second radiator with other wavelength, for overall solidification.
This causes complicated method, wherein equipment spends very high.
Therefore, it is necessary to a kind of cost advantages, be simply to generate surface effect by microplissement in the coating
Method, it is especially desirable to a kind of that surface effect is only partially introduced into method in coating.In addition, should be in the difference on the surface of coating
Region in realize different optics and/or sense of touch effect.
Invention content
The purpose of the present invention is to provide one kind for simply, cost-effectively making paint surface matt by microplissement
The method of change can especially make the side of the subregion on only surface targetedly matt or the characteristic equipped with optics or sense of touch
Method.Here, in the expansion scheme of the present invention, different surface effects can be in the different regions of coating, wherein
The thickness of coating can be different in each region.
Another aspect of the present invention relates to a kind of for executing device according to the method for the present invention and manufactured in this way
Product and the available coating fluid of this method.
The present invention in a manner of unexpectedly simple by according to the method for claim 1, according to independent right
It is required that the device and coating fluid according to claim 24 described in 19 and 23 are realized.On the other hand it is related to according to right
It is required that 29 product manufactured in this way, the surface with microplissement.Preferred embodiment is in corresponding subordinate
In claim.
For can by High energy particles Radiation, particularly by the coating of UV radiation curings in generate surface effect side
Method includes the following steps：
In the first step, by free-radical curable, especially can by the cured coating fluids of UV, for example paint be coated to lining
On bottom.Here, coating fluid so designs, that is, the reaction at the surface of the coated film of coating is thin with the coating in coating
Reaction in the volume of film is targetedly different.
In second step, coating is irradiated, wherein will preferably be radiated with the UV-C of 240nm wavelengths above and introduce coating
Surface layer in.
Therefore, this method based on principle and microplissement such as again by excimer radiation and subsequently through more long wavelength
UV radiation or electron radiation rear solidification realize principle it is identical.But according to the method for the present invention the advantages of, is, surface reaction
Property regulation is at targetedly different from volumetric reaction.It realizes, is radiated using commercial common middle pressure mercury in this way
The UV radiation of the above-mentioned excimer radiation device radiation more long wavelength of ratio of device, such as UV-C are radiated and are generated microplissement at surface.
The reactivity worth on the surface of the coated film of coating is targetedly adjusted to difference relative to the reactivity worth of volume and also causes
Effect depending on thickness.Therefore, thin layer keeps glossy, and thicker layer matt in the process according to the present invention.
Another advantage according to the method for the present invention is, the curing reaction of surface and volume is using in common in the industry
Mercury radiator is pressed to cause.User need not carry out additional investment or carry out the change of its equipment as a result,.
According to the effect of method based on such component for adjusting coating fluid so that at the surface of the coated film of coating
Reactivity worth be targetedly different from reactivity worth in the inside of the coated film of coating.
This is achieved in, that is, distributes two different photoinitiators for coating fluid, they differently work, especially
So that a kind of photoinitiator is lifted at the reactivity worth in the region of near surface of the coated film of coating, and another light draws
It sends out agent and promotes the reactivity worth in the inside of the coated film of coating.
In the prior art is for the cured methods of UV, although also having used photoinitiator so far.However, to current
Until the problem of be, when not being at typical condition, i.e. the paint or coating fluid for handling this UV curable under an inert gas,
It is suppressed due to oxygen by the chain reaction that photoinitiator starts.This cause coating coated film by the area of near surface
The solidification in domain is less than in its volume, and correspondingly, and the surface of skin of paint only has low hardness or may still be entirely liquid
State.
In order to overcome the difficult point, the prior art to propose two kinds of solutions：
Handled under inert conditions, so as to therefore avoid the formation of free radical and oxygen competitive reaction the problem of,
Or
Improve the content of photoinitiator.
Here, two kinds of solutions all have the disadvantage.For example, solidification under inert conditions leads to the equipment improved flower
Take.On the other hand, if promoting the content of photoinitiator, the wind that photoinitiator is migrated out from cured coating is improved simultaneously
Danger, this is for food packaging especially severe.The migration of promotion can rule of thumb be attributed to not all photoinitiator and be converted, and
It is always to also have unconverted component residual.Because the photoinitiator used is usually movable small molecule, it is retained in solidification
Film in fraction can move out and be transferred in the case of packaging in interior packet object from film.
In addition, also only making sure that the inside of the skin of paint by the region of near surface and coating is substantially uniform in this way
Solidification, that is, almost there is by the region of near surface with inside enamelled coating the identical degree of cross linking.By the region of near surface compared to enamelled coating
Internal causes becoming apparent from for microplissement not realized using above-mentioned solution with crosslinking earlier.
Therefore, it in order to realize that the paint film of coating cures earlier by the region of near surface, needs to use excimer radiation
Device.The surface reaction realized in the case where being radiated using excimer radiation device is based on for example directly acting on by the radiation waiting for
The reaction of the acrylate monomer of polymerization.However, excimer radiation device radiation absorption with penetration depth rise and exponentially
Grade declines, to can only make in this way by the regions curing of near surface.And in order to make in the inside of the enamelled coating of coating
It is reacted, it is also necessary to be irradiated using the UV of more long wavelength.Therefore, using the known method of the prior art, exist in two steps
Radiated using excimer radiation device and the second radiation source of more long wavelength in the case of carry out, you can forming microplissement
In the case of realize by near surface region targetedly solidification.As already described, this method also results in
The equipment of raising is spent.
Therefore, according to the method for the present invention with art methods except that compared with so far for the table of coating
Layer microplissement and therefore in order to generate surface effect, need the less radiation of apparent energy.Such as using with
The UV radiation of 240nm wavelengths above has been enough to generate microplissement, and so far using the standard with wavelength 172nm and 222nm
Molecular radiators, wherein only the wavelength of 172nm is appropriate to generates free radicals in the case where not using photoinitiator.It is existing
In the method according to the invention, it is no longer necessary to the device of this costliness.But by can be used according to the method for the present invention
Other radiation sources.

Line is injected with less dosage, and so that film is cmpletely cured in second step, wherein is used for two curing schedules
The UV of longer wavelength is radiated, such as the UV of middle pressure UV radiators is radiated.
However, another embodiment according to the present invention, microplissement and film can be also realized in irradiating step
It is fully cured.For this purpose, correspondingly designing coating material particularly by Change of absorption of the UV radiation in the thickness of coating media.
According to embodiment of the present invention, microplissement and the irradiation phase for solidify coating are generated in surface layer
It should be realized by means of middle pressure mercury radiator.
In another embodiment of the present invention, middle pressure mercury radiator, the preferably same middle pressure mercury radiator are for irradiating
Surface layer and solidify coating.Here, the dosage of adjustment UV radiation is by pressing the power of mercury radiator to realize in adjusting.
Another embodiment according to the present invention, coating may make the such coated film of acquisition, in determining region
In have different thickness.It can get in the region with corresponding different thickness different.
If the feel of coating is important, for example, if the region of the determination of coating can be perceived by touching,
This is for example advantageous.Equally, it can be advantageously carried out the optical design of the product of coating to have a great attraction in this way.
