Definitions
- the present invention relates to a method for producing a digital print structured wear protection film, in particular by negative structuring, with an adjustable degree of gloss.
- the present invention also relates to a structured wear protection film, the use of a structured wear protection film and a decorative panel with a structured wear protection film.
- Structured surfaces for wear protection are known per se and are used in particular to protect decorative panels.
- decorative panel is to be understood as meaning wall, ceiling, door or floor panels which have a decoration applied to a carrier plate.
- Decorative panels are used in a variety of ways both in the area of interior design of rooms and for the decorative cladding of buildings, for example in trade fair construction.
- One of the most common areas of application for decorative panels is their use as floor covering, to cover ceilings, walls or doors.
- the decor panels often have a decor and a surface structure that is intended to imitate a natural material.
- wear or cover layers are generally applied above the decorative layer.
- a surface structuring imitating a decorative template is introduced into such wear or cover layers, so that the surface of the decorative panel has a has haptically perceptible structure, which is adapted to its shape and its pattern to the applied decor in order to obtain a replica of a natural material that is as true to the original as possible, also with regard to the haptics.
- a disadvantage of such methods can be that in particular the formation of small and locally limited structures, such as pores, is only possible with great difficulty.
- the exact alignment of the embossing tools relative to the decor can cause problems.
- variations in the structure can only be implemented with great effort and, for example, small production series are comparatively uneconomical, since embossing tools have to be manufactured and exchanged for each series.
- embossing tools have to be manufactured and exchanged for each series.
- the invention provides a method for producing a structured
- Proposed wear protection film comprising the process steps: a. Providing a wear protection base film, b. Applying a formable, lacquer-containing top layer to at least a partial area of the wear protection base film, c. At least partial structuring of the lacquer-containing top layer with a digital printing process to produce a structuring of the lacquer-containing top layer, and d. Curing the lacquer-containing top layer in such a way that the lacquer-containing top layer is first partially cured, with UV radiation having a wavelength in a range from> 150 nm to ⁇ 250 nm being used for partial curing, and the lacquer-containing top layer then being finally cured; and where e.
- the lacquer-containing top layer before being fed to the printing unit for partially structuring the lacquer-containing top layer and / or during the printing process for partially structuring the lacquer-containing top layer in the printing unit is treated with means for changing the electrostatic charge of the top layer by electrostatically discharging the top layer.
- a method described above allows significant advantages over the solutions from the prior art. It has surprisingly been shown that when a structure is produced in a formable, lacquer-containing cover layer on a wear protection film using a digital printing process, a particularly detailed structuring of the wear protection surface can be obtained. In addition, it has been shown that the structure can be aligned particularly easily relative to a decor in various ways. In addition, an economical production of small series is made possible, since no embossing tools have to be made, and restrictions in process management are reduced, since a particularly stable substrate is not required.
- structured wear protection film is to be understood in the context of the invention as a film that can be applied to panels or other material, has haptically perceptible structures and protects against wear.
- wear protection base film is to be understood in the context of the invention as a film that can be applied to panels or other material, does not have to have any special structuring and can serve as a substrate for applying structures.
- malleable is to be understood as meaning a material which is plastically deformable, that is to say changes its shape through the action of force.
- the material can be liquid or solid, for example.
- the paint-containing top layer can be shaped, for example, by means of a suitable setting of the viscosity of the paint-containing top layer.
- digital printing process is to be understood in the context of the invention as a computer-controlled direct printing process.
- the term “hardening” is to be understood as meaning that the malleable material loses its malleability.
- a liquid moldable material be solidified.
- a plastically deformable solid can be converted into an elastically deformable solid, for example by hardening.
- the material can partially lose its malleability, that is to say lose its malleability at certain points, for example on the surface. It can also be understood to mean that the malleability is only reduced and the material does not become completely non-malleable. It can also be understood to mean complete hardening or final hardening.
- An above-described method for producing a wear protection film thus serves in particular for the improved production of structured surfaces for wear protection.
- a wear protection base film provides a substrate on which structuring can take place.
- a structurable layer is provided which is characterized by the
- Wear protection base film is held and can therefore be easily shaped and nevertheless can be guided through the process with the wear protection base film.
- a digital printing process for generating a structuring of the lacquer-containing top layer can produce a structuring of the lacquer-containing top layer that is particularly true to detail. Since no embossing tools have to be used in the digital printing process, the wear protection base film as a substrate can provide sufficient stability for the structuring. By subsequently hardening the now structured, lacquer-containing top layer, the introduced structure is fixed so that it remains essentially unchanged even when a force is applied.
- the partial curing of the lacquer-containing top layer which has in particular a UV-curable lacquer, with the preferably monochromatic radiation of a wavelength in a range from> 150 nm to ⁇ 250 nm, i.e. with very short-wave UV rays, leads to polymerization in the top layer of the paint.
- a thin hardened film forms on the surface because the penetration depth of the radiation is limited. Since the polymerization also causes volume shrinkage, which in turn manifests itself in surface folds of different strengths, the near-surface film has micro-folds, which leads to a diffuse reflection of the light and thus to a matt surface.
- the wear protection base film with the applied and structured paint-containing top layer is preferably conveyed through a low-oxygen or low-oxygen chamber. This is done, for example, by supplying nitrogen to the area in which the lacquer-containing top layer is cured with the UV radiation.
- the method allows very adaptable degrees of gloss to be set. Because, for example, through the parameters of the partial hardening, the folding of the surface layer and thereby the matting or the degree of gloss are highly defined in the desired manner reproducibly adjustable. This thus allows an effective and well-definable adaptivity of the degree of gloss of the protective layer.
- Such a matting of the surface include, for example, matting down to extremely low degrees of gloss without further matting agents, which can make the process simple and economical, with high reproducibility also being possible.
- Exemplary parameters of the partial curing include, for example, non-limiting monochromatic wavelengths of, for example, 172 nm or 222 nm. Furthermore, a lamp power in a range of 10-25 W / cm and / or a dose rate of 10-30 mW / cm 2 can be advantageous. Possible line speeds of up to 100m / min per emitter are possible.
- ozone can form at such wavelengths, it can be advantageous to carry out the pre-curing of the lacquer-containing top layer in such a way that the surface does not come into contact with oxygen, or only to a limited extent.
- a closed chamber with nitrogen feed can be used at least for partial curing.
- the lacquer-containing top layer to be partially cured in an atmosphere is present that has an oxygen content that is reduced to normal ambient air, for example under a protective gas atmosphere, for example a nitrogen atmosphere.
- the residual oxygen content in the set atmosphere is preferably in a range between> 10 ppm and ⁇ 300 ppm, in particular between> 100 ppm and ⁇ 200 ppm. With such a reduced oxygen compared to the ambient air, partial curing results have surprisingly been achieved particularly well.
- drying can be carried out with particularly short wavelengths. It can be achieved that the UV radiation is absorbed comparatively less. In addition, it can be achieved that the UV radiation does not cause any reactions in the air, such as the reaction to ozone. In addition, undesired surface reactions can be avoided, so that a particularly stable surface is created.
- a fixing step takes place in which the structuring introduced is carried out by means of irradiation at a wavelength in the range from 350 nm to 410 nm, preferably 390 nm to 400 nm, such as 395 nm, for example, in order to prevent the structures produced from diverging.
- a fixing can for example take place by means of LED emitters and thus in particular with low energy.
- the structured lacquer-containing cover layer is first gelled by means of further irradiation at a wavelength in the range from 350 nm to 410 nm.
- the amount of energy introduced to gel the structured cover layer is preferably greater, in particular significantly greater, than that in the upstream fixation s step amount of energy introduced. Gelling can particularly preferably take place using a gallium radiator.

- the lacquer-containing top layer is irradiated with UV radiation from a radiation source with a power of> 5 to ⁇ 200 W / cm in the second curing step, or during the final curing.
- the hardening begins less than 5 s, preferably less than 2 s, in particular less than 0.5 s, after structuring. This advantageously ensures that the structuring does not change as a result of subsequent deliquescence prior to hardening.
- the moldable, lacquer-containing cover layer is pre-cured prior to structuring.
- the viscosity of the paint-containing top layer can be adapted.
- the structuring can be generated in a particularly detailed manner.
- This can also be understood to mean that hardening is set in motion shortly before structuring, so that during structuring the structures formed achieve a hardness that is sufficient to avoid subsequent deliquescence before final hardening.
- the lacquer-containing cover layer in particular with the wear protection base film, is treated with means for changing the electrostatic charge before it is fed to the printing unit for partially structuring the lacquer-containing cover layer and / or during the printing process for partially structuring the lacquer-containing cover layer in the printing unit with means for changing the electrostatic charge by at least the lacquer-containing cover layer Is electrostatically discharged, the structuring can be further improved.

That would cause an unwanted or undefined change in the structure.

Alternatively or additionally, it can be provided that the electrostatic charging is carried out in a range from greater than OkV to less than or equal to 15 kV.
