Definitions
- the present invention relates to a wood-based panel according to the preamble of claim 1 and a method for its production according to claim 14.
- Laminate flooring has become established in the global flooring market over the past twenty years, although there is still no saturation in many submarkets. This success and the high acceptance of laminate flooring is based above all on the good property profile and the possibility of imitation of wooden floors. Another positive aspect is that the covering is predominantly made of wood and thus has ecological advantages over many other floor coverings.
- laminate floors also have some drawbacks that relate in part to the backing plate and partly to the surface.
- the surface of laminate floors usually consists of a cured synthetic resin.
- This resin is typically a melamine-formaldehyde resin from which, among other things, utensils such as crockery and cutlery are made.
- a surface of melamine resin is particularly criticized that it feels hard and cold when walking or when touching. This phenomenon is caused by other plastics - high thermal conductivity.
- the present invention is therefore based on the object to provide a provided with a resin layer wood material panel, in particular in the form of a laminate floor, with a user-improved feel. In doing so, previous positive product characteristics should be changed as little as possible and no significant technical or financial expenditures should be necessary.
- a mixture of silanes of the general formula (I) can also be used.
- the radical X is advantageously selected from a group comprising fluorine, chlorine, bromine, iodine, C 1-6 -alkoxy, in particular methoxy, ethoxy, n-propoxy and butoxy, C 6-10 -aryloxy, in particular phenoxy, C 2-7 -Acyloxy, in particular acetoxy or propionoxy, C 2-7 alkylcarbonyl, in particular acetyl, monoalkylamino or dialkylamino with C 1 to C 12 , in particular C 1 to C 6 .
- Particularly preferred hydrolyzable groups are C 1-4 alkoxy groups, especially methoxy and ethoxy.
- non-hydrolyzable organic radical is to be understood as meaning an organic radical which does not lead to the formation of an OH group or NH 2 group linked to the Si atom in the presence of water.
- the nonhydrolyzable radical R 1 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, and substituted C 3 -C 8 -cycloalkyl.

- the primer layer is preferably applied to a resin layer of a conventionally produced wood-based panel.
- the resin layer can - but does not necessarily have to be sanded - before applying the primer layer; this depends on the nature of the resin layer.
- the advantage of sanding the resin layer prior to application of the primer layer is improved adhesion of the primer layer to the resin layer.
- the resin layer is composed of a formaldehyde resin as a polycondensate, in particular a melamine-formaldehyde resin, a melamine-urea-formaldehyde resin or urea-formaldehyde resin.
- the resin layer can be arranged directly or directly on the surface of the carrier plate.

- the resin layer may have various additives such as natural or synthetic fibers, flame retardants, dyes or abrasion-resistant particles. In general, various variants of the resin layer provided on the carrier plate are conceivable.
- a particularly good adhesion of the primer layer to the resin layer is effected, which is particularly caused by the specific substituents.
- the OH group may undergo a preferential interaction with the matrix of the resin layer.
- a mixture of silanes of the general formula (II) can also be used.
- the non-hydrolyzable radical R 2 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, substituted-substituted C 2 -C 6 -alkenyl, substituted C 3 -C 8 -cycloalkyl and substituted substituted C 3 -C 8 cycloalkenyl.

- the functional group Q 2 accordingly advantageously has a radical with a double bond or an epoxide group which can be activated and polymerized by means of UV radiation. This allows hardening of the topcoat layer by means of UV irradiation.
- Typical compounds of general formula (II) which may be used in the topcoat layer are methacryloxypropyltrimethoxysilane (MPTS), aminoethylaminopropyltrimethoxysilane, silanes having an epoxy functionalization such as glycidyloxypropyltriethoxysilane, or silanes having a vinylfunctionalization such as e.g. Vinyltrimethoxysilane.

- the present wood-based panel has no so-called polishing effects, which typically occur in the production or use of very matt surfaces.
- Polishing effects for example in the form of shiny spots, occur, for example, when cleaning conventional matt surfaces with a soft cloth (polishing) or when sliding furniture with felt glides over a floor covering with a corresponding surface.
- These glossy spots can no longer be removed and, in addition to the matte surface of the surface of the utility object, are particularly easily recognizable, as a result of which the visual impression of the product is very damaged.
- conventional matte surfaces have not been able to secure any relevant market share in the past, although the surface has been found to be haptic as well as soft general impression is perceived as very pleasant. It is all the more surprising that such polishing effects do not occur in the case of the present wood-based panel.

- the material plate may comprise at least one decorative layer and / or at least one sound-insulating layer.
- the decorative layer is preferably provided between the carrier plate and the resin layer.
- the decors for the upper surfaces of the carrier plates can be printed on a paper layer or directly on the plate-shaped base. Such decors are for example wood or stone imitations. Fantasy decors are also possible. These can result, for example, from modifications of natural materials.
- the sound insulating layer is preferably disposed on the underside of the support plate opposite to the resin layer.
- sound-insulating layers come networked PE mats with thicknesses of 1.0 mm or 0.3 to 3 mm thick filled heavy foils, but also foamed PE or PU foils for use.
- pigments such as color pigment or the like, are contained in the topcoat layer.
- a further modification of the topcoat layer may consist in introducing structures such as depressions or elevations into the topcoat layer.
- Such structures can be produced with structured application rollers in the topcoat layer, which can be adapted to the decors used if necessary and / or desired.
- Such methods for structuring surfaces are, for example, from EP 2 251 501 B1 known.
- the wood-based panel according to the present invention can be used as a floor panel but also as a wall panel, ceiling panel or furniture panel due to the improved feel.
- the resin layer arranged on the carrier plate is ground before the application of the primer layer.
- the sanding can be done using a sanding machine with e.g. an 80 grit take place.
- the grain of the grinding machine is dependent on the properties (thickness, composition) of the resin layer and adjusted accordingly.
- the cleaning of the ground resin layer can be carried out by conventional methods, e.g. done with a brush.
- Solvents are especially suitable alcohols such as methanol, ethanol, propanol and butanol.
- the application of the primer layer can be done with a roll coater or by any other known method.
- the primer layer is then dried or flashed off at room temperature. This process can be assisted by using an IR emitter.
- the topcoat layer containing at least one of the silane compounds of the general formula (II) is then applied to the primer layer in an amount of 5 to 30 g / m 2 , preferably 10 to 20 g / m 2 , particularly preferably 10 to 15 g / m 2 .
- solvents such as methanol, ethanol, propanol and butanol.
- the application of the topcoat can also be done with the aid of a roll coater or other known application methods.

- the nanoparticles can be mixed in an amount of 5 to 30% by weight, preferably 10 to 20% by weight, particularly preferably 15% by weight, based on the topcoat layer.
- the subsequent hardening or curing of the topcoat layer in the next process step takes place by UV irradiation, e.g. with a gallium radiator.
- the present material plate has a number of advantages over the conventional material plates.
- the primer used contains a small amount of solvent, which is acceptable due to the low application rate.
- the topcoat is a UV system which can be adjusted to different gloss levels by adding matting agents.

Description
Die vorliegende Erfindung betrifft eine Holzwerkstoffplatte gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zu deren Herstellung gemäß Anspruch 14.The present invention relates to a wood-based panel according to the preamble of
Gegenwärtig werden jedes Jahr weltweit mehrere hundert Millionen Quadratmeter Holzwerkstoffplatten, insbesondere in Form von Laminatböden, hergestellt und verkauft. Laminatböden haben sich in den letzten zwanzig Jahren im weltweiten Fußbodenmarkt etabliert, wobei in vielen Teilmärkten allerdings noch keine Sättigung zu beobachten ist. Dieser Erfolg und die hohe Akzeptanz von Laminatböden beruht vor allem auf dem guten Eigenschaftsprofil und der Möglichkeit der Imitation von Holzfußböden. Ein weiterer positiver Aspekt ist, dass der Belag zum überwiegenden Teil aus Holz besteht und somit ökologische Vorteile gegenüber vielen anderen Bodenbelägen besitzt.At present, several hundred million square meters of wood-based panels, especially in the form of laminate flooring, are produced and sold worldwide each year. Laminate flooring has become established in the global flooring market over the past twenty years, although there is still no saturation in many submarkets. This success and the high acceptance of laminate flooring is based above all on the good property profile and the possibility of imitation of wooden floors. Another positive aspect is that the covering is predominantly made of wood and thus has ecological advantages over many other floor coverings.
Allerdings weisen Laminatböden auch einige Nachteile auf, die sich zum Teil auf die Trägerplatte und zum Teil auf die Oberfläche beziehen.However, laminate floors also have some drawbacks that relate in part to the backing plate and partly to the surface.
So besteht die Oberfläche von Laminatböden üblicherweise aus einem ausgehärteten Kunstharz. Dieses Kunstharz ist typischerweise ein Melamin-Formaldehyd-Harz, aus dem unter anderem auch Gebrauchsgegenstände wie Geschirr und Besteck hergestellt werden. Bei einer Oberfläche aus Melaminharz wird insbesondere bemängelt, dass sie sich beim Begehen oder beim Anfassen hart und kalt anfühlt. Dieses Phänomen wird durch diegegenüber anderen Kunststoffen - hohe Wärmeleitfähigkeit verursacht.Thus, the surface of laminate floors usually consists of a cured synthetic resin. This resin is typically a melamine-formaldehyde resin from which, among other things, utensils such as crockery and cutlery are made. In a surface of melamine resin is particularly criticized that it feels hard and cold when walking or when touching. This phenomenon is caused by other plastics - high thermal conductivity.
Zur Verbesserung der Haptik von Laminatböden wurde in der Vergangenheit der Ansatz versucht, Melaminharz-Oberflächen nach zu lackieren. Dabei hat sich jedoch regelmäßig gezeigt, dass sich auf einer ausgehärteten Melaminharz-Oberfläche keine guten Haftungsergebnisse erzielen ließen. Außerdem betraf dieses Überlackieren meist nur Möbeloberflächen, bei denen die mechanische Beanspruchung deutlich geringer ist als bei Bodenbelägen. Allenfalls bei der Verwendung von sehr hochwertigen Polyurethan-Lacken ließen sich nur nach Anschliff gute Haftungsergebnisse erreichen. Allerdings sind diese Lacke teuer und sind zudem technisch anspruchsvoll.To improve the feel of laminate floors, attempts have been made in the past to paint melamine resin surfaces. However, it has been shown regularly that it was not possible to achieve good adhesion results on a cured melamine resin surface. In addition, this recoating mostly concerned only furniture surfaces in which the mechanical stress is significantly lower than in floor coverings. At best, when using very high-quality polyurethane paints, good adhesion results could only be achieved after sanding. However, these paints are expensive and are also technically demanding.
Beim Einsatz von anderen Lacken konnte nur bei ganz speziell vorbereiteten Melaminoberflächen befriedigende Haftungsergebnisse erzielt werden. Dazu musste bereits bei der Herstellung der Melaminoberflächen darauf geachtet werden, dass die Oberfläche möglichst wenig ausgehärtetes Melaminharz enthält. Dies wurde während des Imprägnierprozesses der dekorativen Papiere durch eine sehr niedrige Beharzung erreicht. Damit wurden nach der Beschichtung von Holzwerkstoff-Platten in der Kurztaktpresse Oberflächen erzielt, die eine leichte Porosität der Oberfläche besaßen. Man nennt diese Beschichtungsvariante Grundierfolien. Selbst diese Oberflächen mussten jedoch vor der Lackierung aufwändig gereinigt und geschliffen werden.When using other paints, satisfactory adhesion results could only be achieved with specially prepared melamine surfaces. For this purpose, care had to be taken during the production of the melamine surfaces that the surface contains as little hardened melamine resin as possible. This was achieved during the impregnation process of the decorative papers by a very low tankage. Thus, surfaces were obtained after the coating of wood-based panels in the short-cycle press, which had a slight porosity of the surface. This coating variant is called primer films. Even these surfaces, however, had to be laboriously cleaned and sanded before painting.
Somit besteht nach wie vor ein sehr großer Bedarf an Laminaten mit einer ausgehärteten Melaminharzoberfläche mit den daraus resultierenden guten Eigenschaften einerseits und einer wärmeren und weicheren Haptik andererseits.Thus, there is still a very large demand for laminates with a cured melamine resin surface with the resulting good properties on the one hand and a warmer and softer feel on the other.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine mit einer Harzschicht versehene Holzwerkstoffplatte, insbesondere in Form eines Laminatbodens, mit einer für den Benutzer verbesserten Haptik auszustatten. Dabei sollten bisherige positive Produkteigenschaften so wenig wie möglich verändert werden und auch keine erheblichen technischen oder finanziellen Aufwendungen nötig sein.The present invention is therefore based on the object to provide a provided with a resin layer wood material panel, in particular in the form of a laminate floor, with a user-improved feel. In doing so, previous positive product characteristics should be changed as little as possible and no significant technical or financial expenditures should be necessary.
Diese Aufgabe wird erfindungsgemäß durch eine Werkstoffplatte mit den Merkmalen des Anspruchs 1 und ein Verfahren zu deren Herstellung mit den Merkmalen des Anspruchs 14 gelöst.This object is achieved by a material plate having the features of
Entsprechend wird eine Holzwerkstoffplatte mit einer matten Oberfläche, die keinen Aufpoliereffekt aufweist, bereitgestellt, die mindestens eine Trägerplatte und mindestens einer auf mindestens einer Seite der Trägerplatte angeordnete Harzschicht umfasst. Auf der mindestens einen Harzschicht ist mindestens eine Primerschicht angeordnet, wobei die mindestens eine Primerschicht mindestens eine Verbindung mit der allgemeinen Formel (I)

Besonders bevorzugte hydrolysierbare Gruppen sind C1-4 Alkoxygruppen, insbesondere Methoxy und Ethoxy.The radical X is advantageously selected from a group comprising fluorine, chlorine, bromine, iodine, C 1-6 -alkoxy, in particular methoxy, ethoxy, n-propoxy and butoxy, C 6-10 -aryloxy, in particular phenoxy, C 2-7 -Acyloxy, in particular acetoxy or propionoxy, C 2-7 alkylcarbonyl, in particular acetyl, monoalkylamino or dialkylamino with C 1 to C 12 , in particular C 1 to C 6 . Particularly preferred hydrolyzable groups are C 1-4 alkoxy groups, especially methoxy and ethoxy.
Unter dem Begriff "nicht-hydrolysierbarer organischer Rest" ist im Rahmen der vorliegenden Anmeldung ein organischer Rest zu verstehen, der in Gegenwart von Wasser nicht zur Bildung einer mit dem Si-Atom verknüpften OH-Gruppe oder NH2-Gruppe führt.In the context of the present application, the term "non-hydrolyzable organic radical" is to be understood as meaning an organic radical which does not lead to the formation of an OH group or NH 2 group linked to the Si atom in the presence of water.
Der nicht hydrolisierbare Rest R1 ist bevorzugt ausgewählt aus einer Gruppe umfassend substituiertes C1-C30-Alkyl, insbesondere C5-C25-Alkyl, und substituiertes C3-C8-Cycloalkyl.The nonhydrolyzable radical R 1 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, and substituted C 3 -C 8 -cycloalkyl.
Es ist insbesondere von Vorteil, wenn der Rest R1 ausgewählt ist aus der Gruppe enthaltend Methyl, Ethyl, n-Propyl, Isopropyl, n-Butyl, s-Butyl, t-Butyl, Pentyl, Hexyl und Cyclohexyl, bevorzugt Methyl, Ethyl oder Propyl.It is particularly advantageous if the radical R 1 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, s-butyl, t-butyl, pentyl, hexyl and cyclohexyl, preferably methyl, ethyl or propyl.
Die mindestens eine funktionelle Gruppe Q1, die im organischen nicht hydrolysierbaren Rest enthalten sein kann, umfasst bevorzugt eine Aminogruppe, eine Monoalkylaminogruppe oder substituierte oder nicht substituierte Silyl-Gruppe, eine Arylgruppe, insbesondere eine Phenylgruppe, und eine Hydroxygruppe.The at least one functional group Q 1 , which may be contained in the organic non-hydrolyzable group, preferably includes an amino group, a monoalkylamino group or substituted or unsubstituted silyl group, an aryl group, especially a phenyl group, and a hydroxy group.
Typische Verbindungen der allgemeinen Formel (I), die in der Primerschicht zum Einsatz kommen können, sind z.B. Bis(3-trimethoxysilyl-propyl)amin, Aminopropyltrimethoxysilan, Aminopropyltriethoxysilan, 3-Aminopropyl-methyl-dimethoxysilan, 3-Aminopropyl-methyldiethoxysilan, N-(n-butyl)-3-aminopropyl-trimethoxysilan, N-(n-butyl)-3-aminopropyltriethoxysilan, Aminoethyl-aminopropyltrimethoxysilan oder Aminoethylaminopropyltriethoxysilan.Typical compounds of general formula (I) which can be used in the primer layer are e.g. Bis (3-trimethoxysilylpropyl) amine, aminopropyltrimethoxysilane, aminopropyltriethoxysilane, 3-aminopropylmethyldimethoxysilane, 3-aminopropylmethyldiethoxysilane, N- (n-butyl) -3-aminopropyltrimethoxysilane, N- (n-butyl) - 3-aminopropyltriethoxysilane, aminoethylaminopropyltrimethoxysilane or aminoethylaminopropyltriethoxysilane.
Die Primerschicht wird bevorzugt auf eine Harzschicht einer konventionell hergestellten Holzwerkstoffplatte aufgetragen. Die Harzschicht kann - muss aber nicht zwingend - vor dem Auftrag der Primerschicht angeschliffen werden; dies ist abhängig von der Beschaffenheit der Harzschicht. Der Vorteil des Anschleifens der Harzschicht vor dem Auftrag der Primerschicht besteht in einer verbesserten Haftung der Primerschicht auf der Harzschicht.The primer layer is preferably applied to a resin layer of a conventionally produced wood-based panel. The resin layer can - but does not necessarily have to be sanded - before applying the primer layer; this depends on the nature of the resin layer. The advantage of sanding the resin layer prior to application of the primer layer is improved adhesion of the primer layer to the resin layer.
In einer Ausführungsform der vorliegenden Werkstoffplatte besteht die Harzschicht aus einem Formaldehyd-Harz als einem Polykondensat, insbesondere einem Melamin-Formaldehyd-Harz, einem Melamin-Harnstoff-Formaldehyd-Harz oder Harnstoff-Formaldehyd-Harz.In one embodiment of the present material plate, the resin layer is composed of a formaldehyde resin as a polycondensate, in particular a melamine-formaldehyde resin, a melamine-urea-formaldehyde resin or urea-formaldehyde resin.
Die Harzschicht kann unmittelbar bzw. direkt auf der Oberfläche der Trägerplatte angeordnet sein. Die Harzschicht kann aber auch auf einem Dekorpapier aufgetragen sein, welches wiederum auf der Trägerplatte angeordnet ist. Ebenfalls ist es vorstellbar, dass die Harzschicht auf einer direkt auf der Trägerplatte aufgedruckten Dekorschicht aufgetragen ist. Auch kann die Harzschicht verschiedene Additive wie natürliche oder synthetische Fasern, Flammschutzmittel, Farbstoffe bzw. Farbpigmente oder abriebfeste Partikel aufweisen. Generell sind verschiedene Varianten der auf der Trägerplatte vorgesehen Harzschicht denkbar.The resin layer can be arranged directly or directly on the surface of the carrier plate. The resin layer can also be applied to a decor paper, which in turn is arranged on the support plate. It is also conceivable that the resin layer is applied to a directly on the support plate printed decor layer. Also, the resin layer may have various additives such as natural or synthetic fibers, flame retardants, dyes or abrasion-resistant particles. In general, various variants of the resin layer provided on the carrier plate are conceivable.
Durch die Verwendung einer Silanverbindung der allgemeinen Formel (I) in der Primerschicht wird eine besonders gute Haftung der Primerschicht auf der Harzschicht, z.B. Melaminharzschicht, bewirkt, die insbesondere durch die spezifischen Substituenten hervorgerufen wird. So kann z.B. die OH-Gruppe eine bevorzugte Wechselwirkung mit der Matrix der Harzschicht eingehen.By using a silane compound of the general formula (I) in the primer layer, a particularly good adhesion of the primer layer to the resin layer, eg melamine resin layer, is effected, which is particularly caused by the specific substituents. For example, the OH group may undergo a preferential interaction with the matrix of the resin layer.
Erfindungsgemäß ist auf der mindestens einen Primerschicht mindestens eine Schicht aus einem Decklack angeordnet, wobei der mindestens eine Decklack mindestens eine Verbindung der allgemeinen Formel (II)
R2 aSiX(4-a) (II),
und/oder deren Hydrolyseprodukte aufweist, wobei

- wobei R2 mindestens eine funktionelle Gruppe Q2 aufweist, die ausgewählt ist aus einer Gruppe enthaltend eine Epoxid-, Alkenyl-, Alkinyl-, Acryl-, Acryloxy-, Methacryl-, Methacryloxy-, Cyano- und Isocyano-Gruppe, und
- a = 1, 2, 3, insbesondere 1 oder 2 ist.

- R 2 is a non-hydrolyzable organic radical R 2 is selected from the group consisting of substituted alkyl, substituted aryl, substituted alkenyl, substituted alkynyl, substituted cycloalkyl, substituted cycloalkenyl which may be interrupted by -O- or -NH-, and
- wherein R 2 has at least one functional group Q 2 selected from a group containing an epoxide, alkenyl, alkynyl, acrylic, acryloxy, methacrylic, methacryloxy, cyano and isocyano group, and

In einer bevorzugten Ausführungsform kann auch ein Gemisch von Silanen der allgemeinen Formel (II) verwendet werden.In a preferred embodiment, a mixture of silanes of the general formula (II) can also be used.
Der nicht-hydrolisierbare Rest R2 ist bevorzugt ausgewählt aus einer Gruppe umfassend substituiertes C1-C30-Alkyl, insbesondere C5-C25-Alkyl, substituiertessubstituiertes C2-C6-Alkenyl, substituiertes C3-C8-Cycloalkyl und substituiertes substituiertes C3-C8-Cycloalkenyl.The non-hydrolyzable radical R 2 is preferably selected from a group comprising substituted C 1 -C 30 -alkyl, in particular C 5 -C 25 -alkyl, substituted-substituted C 2 -C 6 -alkenyl, substituted C 3 -C 8 -cycloalkyl and substituted substituted C 3 -C 8 cycloalkenyl.
Es ist insbesondere von Vorteil, wenn der nicht-hydrolisierbare R2 ausgewählt ist aus der Gruppe enthaltend Methyl, Ethyl, n-Propyl, Isopropyl, n-Butyl, s-Butyl, t-Butyl, Pentyl, Hexyl, Cyclohexyl, Vinyl, 1-Propenyl, 2-Propenyl, Butenyl, Acetylenyl, Propargyl, substituiertes substituiertes Butadienyl oder substituiertes Cyclohexadienyl, bevorzugt Methyl, Ethyl, Propyl oder Vinyl.It is particularly advantageous if the nonhydrolyzable R 2 is selected from the group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, s-butyl, t-butyl, pentyl, hexyl, cyclohexyl, vinyl, 1 Propenyl, 2-propenyl, butenyl, acetylenyl, propargyl, substituted substituted butadienyl or substituted cyclohexadienyl, preferably methyl, ethyl, propyl or vinyl.
Die mindestens eine funktionelle Gruppe Q2, die im Rest R2 enthalten sein kann, umfasst vorteilhafterweise eine Acrylgruppe, Acryloxygruppe, Methacrylgruppe oder eine Methacryloxygruppe, eine Epoxid-, bevorzugt ein 1,2-Epoxyethyl-Gruppe, eine Glycidyl- oder Glycidyloxy-Gruppe, und/oder eine Isocyano-Gruppe.The at least one functional group Q 2 , which may be contained in the radical R 2 , advantageously comprises an acrylic group, acryloxy group, methacrylic group or a methacryloxy group, an epoxide, preferably a 1,2-epoxyethyl group, a glycidyl or glycidyloxy group , and / or an isocyano group.
Die funktionelle Gruppe Q2 weist demnach vorteilhafterweise einen Rest mit einer Doppelbindung oder einer Epoxid-Gruppe auf, der mittels UV-Strahlung aktivierbar und polymerisierbar ist. Dies ermöglicht eine Härtung der Decklackschicht mittels UV-Bestrahlung.The functional group Q 2 accordingly advantageously has a radical with a double bond or an epoxide group which can be activated and polymerized by means of UV radiation. This allows hardening of the topcoat layer by means of UV irradiation.
Typische Verbindungen der allgemeinen Formel (II), die in der Decklackschicht zum Einsatz kommen können, sind Methacryloxypropyltrimethoxysilan (MPTS), Aminoethylaminopropyltrimethoxysilan, Silane mit einer Epoxyfunktionalisierung wie Glycidyloxypropyltriethoxysilan, oder Silane mit einer Vinylfunktionalisierung wie z.B. Vinyltrimethoxysilan. Wie bereits erwähnt ist es auch denkbar, dass Gemische von Silanverbindungen der allgemeinen Formel (II) in einer Decklackschicht verwendet werden. So kann z.B. das Reaktions- bzw. Hydrolyseprodukt von Methacrylpropyltrimethoxysilan (MPTS) und Aminoethylaminopropyltrimethoxysilan an zum Einsatz kommen.Typical compounds of general formula (II) which may be used in the topcoat layer are methacryloxypropyltrimethoxysilane (MPTS), aminoethylaminopropyltrimethoxysilane, silanes having an epoxy functionalization such as glycidyloxypropyltriethoxysilane, or silanes having a vinylfunctionalization such as e.g. Vinyltrimethoxysilane. As already mentioned, it is also conceivable that mixtures of silane compounds of the general formula (II) are used in a topcoat layer. Thus, e.g. the reaction or hydrolysis product of methacrylpropyltrimethoxysilane (MPTS) and aminoethylaminopropyltrimethoxysilane are used.
Wie oben beschrieben, verfügen die nicht-hydrolisierbaren Reste R1 und R2 jeweils über mindestens eine funktionelle Gruppe Q1 oder Q2. Darüber hinaus können die Reste R1 und R2 auch mit weiteren Resten substituiert vorliegen.As described above, the nonhydrolyzable groups R 1 and R 2 each have at least one functional group Q 1 or Q 2 . In addition, the radicals R 1 and R 2 may also be substituted by further radicals.

In einer weiteren Variante der vorliegenden Holzwerkstoffplatte sind in der mindestens einen Decklackschicht Nanopartikel vorgesehen, die eine Einstellung des Glanzgrades ermöglichen. So können Glanzgrade zwischen 1 und 5, bevorzugt 2 und 4, insbesondere bevorzugt 3 und 3,5 (DIN EN ISO 2813, Messwinkel 85°) eingestellt werden.In a further variant of the present wood-based panel nanoparticles are provided in the at least one topcoat layer, which allow adjustment of the gloss level. Thus, gloss levels between 1 and 5, preferably 2 and 4, particularly preferably 3 and 3.5 (DIN EN ISO 2813, measuring angle 85 °) can be set.
Die vorliegende Holzwerkstoffplatte weist überraschenderweise keine sogenannten Aufpoliereffekte auf, die typischerweise bei der Herstellung bzw. bei der Nutzung sehr matter Oberflächen auftreten. Aufpoliereffekte, z.B. in Form von Glanzstellen, entstehen zum Beispiel bei einer Reinigung von konventionellen matten Oberflächen mit einem weichen Tuch (Polieren) oder beim Schieben von Möbeln mit Filzgleitern über einen Bodenbelag mit entsprechender Oberfläche. Diese Glanzstellen lassen sich nicht mehr entfernen und sind neben der matten Oberfläche der Gebrauchsgegenstandsoberfläche besonders gut erkennbar, wodurch der optische Eindruck des Produktes sehr beschädigt wird. Aus diesem Grund haben sich konventionelle matte Oberflächen in der Vergangenheit keine relevanten Marktanteile sichern können, obwohl die Oberfläche sowohl in der Haptik als auch in der allgemeinen Anmutung als sehr angenehm empfunden wird. Umso überraschender ist es, dass derartige Aufpoliereffekte im Falle der vorliegenden Holzwerkstoffplatte nicht auftreten.Surprisingly, the present wood-based panel has no so-called polishing effects, which typically occur in the production or use of very matt surfaces. Polishing effects, for example in the form of shiny spots, occur, for example, when cleaning conventional matt surfaces with a soft cloth (polishing) or when sliding furniture with felt glides over a floor covering with a corresponding surface. These glossy spots can no longer be removed and, in addition to the matte surface of the surface of the utility object, are particularly easily recognizable, as a result of which the visual impression of the product is very damaged. For this reason, conventional matte surfaces have not been able to secure any relevant market share in the past, although the surface has been found to be haptic as well as soft general impression is perceived as very pleasant. It is all the more surprising that such polishing effects do not occur in the case of the present wood-based panel.
Die bevorzugt verwendeten Partikel weisen eine Größe zwischen 2 und 400 nm, bevorzugt zwischen 2 bis 100 nm aufweist, insbesondere bevorzugt zwischen 2 bis 50 nm auf. Die Partikel können insbesondere von oxidischer, hydroxidischer oder oxihydroxidischer Natur sein, die über unterschiedliche Verfahren wie zum Beispiel Ionenaustauschprozess, Plasma-Prozess, Sol-Gel-Verfahren, Vermahlung oder auch Flammabscheidung, hergestellt werden können. In einer bevorzugten Ausführungsform werden Partikel auf Basis von SiO2, Al2O3, ZrO2, TiO2, SnO verwendet, wobei SiO2-Partikel ganz besonders bevorzugt sind.The preferably used particles have a size between 2 and 400 nm, preferably between 2 to 100 nm, particularly preferably between 2 to 50 nm. In particular, the particles can be of oxidic, hydroxidic or oxihydroxide nature, which can be produced by different processes, for example ion exchange process, plasma process, sol-gel process, grinding or also flame deposition. In a preferred embodiment, particles based on SiO 2 , Al 2 O 3 , ZrO 2 , TiO 2 , SnO are used, with SiO 2 particles being very particularly preferred.
Die vorliegend verwendeten Nanopartikel können eine spezifische Oberfläche von 50 bis 500 m2/g, bevorzugt von 100 bis 400 m2/g, insbesondere bevorzugt von 200 bis 300 m2/g aufweisen. Die Bestimmung der spezifischen Oberfläche erfolgte über Messungen der Adsorption von Stickstoff nach der BET-Methode von Brunauer, Emmett und Teller.The nanoparticles used in the present case may have a specific surface area of from 50 to 500 m 2 / g, preferably from 100 to 400 m 2 / g, particularly preferably from 200 to 300 m 2 / g. The specific surface area was determined by adsorption of nitrogen by the BET method of Brunauer, Emmett and Teller.
Zur Verbesserung der Abrieb-/Verschleißfestigkeit der Decklackschicht können dem Lack auch verschleißhemmende Partikel zugegeben werden. Diese können u. a. aus Aluminiumoxid (Korund), Carbiden usw. bestehen. Wichtig ist dabei, dass die Größe der Partikel auf die Auftragsmenge des Decklacks abgestimmt ist. Die Größe der verschleißhemmenden Partikel kann im Bereich zwischen 1 und 20 µm, bevorzugt 5 und 15 µm, insbesondere bevorzugt zwischen 7 und 12 µm liegen. und Bei einer Schichtdicke des Decklacks von z. B. 10 - 12 µm sollten die verschleißhemmenden Materialien Partikelgrößen von 8 - 10 µm nicht überschreiten. In der Decklackschicht können demnach Nanopartikel und/oder größere abriebfeste Partikel enthalten sein.To improve the abrasion / wear resistance of the topcoat layer, wear-inhibiting particles can also be added to the paint. These can u. a. consist of alumina (corundum), carbides, etc. It is important that the size of the particles is matched to the order quantity of the topcoat. The size of the anti-wear particles may be in the range between 1 and 20 microns, preferably 5 and 15 microns, more preferably between 7 and 12 microns. and at a layer thickness of the topcoat of z. B. 10 - 12 microns, the anti-wear materials should not exceed particle sizes of 8 - 10 microns. Accordingly, nanoparticles and / or larger abrasion-resistant particles can be contained in the topcoat layer.
Wie oben erwähnt, können sowohl in der Primerschicht als auch in der Decklackschicht jeweils Hydrolyseprodukte der mindestens einen Verbindung der allgemeinen Formel (I) in der Primerschicht und/oder der mindestens einen Verbindung der allgemeinen Formel (II) in der Decklackschicht enthalten sein. Derartige Hydrolyseprodukte sind bevorzugt in Gegenwart von mindestens einer hydrolytisch wirksamen Verbindung, insbesondere einer sauer reagierenden Verbindung erhältlich.As mentioned above, hydrolysis products of the at least one compound of the general formula (I) in the primer layer and / or the at least one compound of the general formula (II) may be present in the topcoat layer both in the primer layer and in the topcoat layer.

Prinzipiell kann als Trägerplatte eine Platte aus einem Holzwerkstoff oder aus Kunststoff oder einem Holzwerkstoff-Kunststoff-Gemisch verwendet werden, insbesondere eine Span-, mitteldichte Faser(MDF)-, hochdichte Faser (HDF)- oder Grobspan (OSB)- oder Sperrholzplatten, eine Zementfaserplatte und/oder Gipsfaserplatte.In principle, as a carrier plate, a plate made of a wood material or plastic or a wood-plastic mixture can be used, in particular a chip, medium-density fiber (MDF), high-density fiber (HDF) - or coarse chip (OSB) - or plywood panels, a Cement fiber board and / or gypsum fiber board.
Zusätzlich zu der erfindungsgemäßen Oberflächenschicht aus Harzschicht, Primerschicht und Decklackschicht kann die Werkstoffplatte in einer Ausführungsform mindestens eine Dekorlage und/oder mindestens eine schalldämmende Schicht umfassen.In addition to the surface layer of resin layer, primer layer and topcoat layer according to the invention, in one embodiment the material plate may comprise at least one decorative layer and / or at least one sound-insulating layer.
So ist die Dekorlage bevorzugt zwischen Trägerplatte und Harzschicht vorgesehen. Die Dekore für die oberen Flächen der Trägerplatten können dabei auf einer Papierlage oder direkt auf die plattenförmige Basis gedruckt vorliegen. Solche Dekore sind beispielsweise Holz- oder Steinimitationen. Auch Fantasiedekore sind möglich. Diese können sich beispielsweise aus Abwandlungen von natürlichen Werkstoffen ergeben.Thus, the decorative layer is preferably provided between the carrier plate and the resin layer. The decors for the upper surfaces of the carrier plates can be printed on a paper layer or directly on the plate-shaped base. Such decors are for example wood or stone imitations. Fantasy decors are also possible. These can result, for example, from modifications of natural materials.
Die schalldämmende Schicht ist bevorzugt auf der Unterseite der Trägerplatte, die der Harzschicht gegenüberliegt, angeordnet. Als schalldämmende Schichten kommen vernetzte PE-Matten mit Dicken von 1,0 mm oder 0,3 bis 3 mm dicke gefüllte Schwerfolien, aber auch geschäumte PE- oder PU-Folien zum Einsatz.The sound insulating layer is preferably disposed on the underside of the support plate opposite to the resin layer. As sound-insulating layers come networked PE mats with thicknesses of 1.0 mm or 0.3 to 3 mm thick filled heavy foils, but also foamed PE or PU foils for use.
Auch ist es vorstellbar, wenn in der Decklackschicht weitere Pigmente, wie Farbpigment oder ähnliches enthalten sind.It is also conceivable if further pigments, such as color pigment or the like, are contained in the topcoat layer.
Eine weitere Modifikation der Decklackschicht kann im Einbringen von Strukturen wie z.B. Vertiefungen oder Erhöhungen in die Decklackschicht bestehen. Derartige Strukturen können mit strukturierten Auftragswalzen in der Decklackschicht erzeugt werden, die wenn nötig und/oder gewünscht den verwendeten Dekoren angepasst werden können. Derartige Methoden zur Strukturierung von Oberflächen sind z.B. aus der
Die Holzwerkstoffplatte gemäß der vorliegenden Erfindung ist aufgrund der verbesserten Haptik als Fußbodenplatte aber auch als Wandplatte, Deckenplatte oder Möbelplatte einsetzbar.The wood-based panel according to the present invention can be used as a floor panel but also as a wall panel, ceiling panel or furniture panel due to the improved feel.
Die Herstellung der vorliegenden Holzwerkstoffplatte erfolgt in einem Verfahren mit den folgenden Schritten:
- Auftragen der mindestens einen Primerschicht auf die auf der mindestens einen Seite (Oberseite) der Trägerplatte angeordnete ausgehärtete Harzschicht;
- Auftragen der mindestens einen Decklackschicht auf die Primerschicht;
- optionale Zugabe von Nanopartikeln zur Decklackschicht zur Einstellung des Glanzgrades, und
- Aushärten der Decklackschicht durch UV-Bestrahlung.
- Applying the at least one primer layer to the cured resin layer disposed on the at least one side (upper side) of the carrier plate;
- Applying the at least one topcoat layer to the primer layer;
- optional addition of nanoparticles to the top coat layer to adjust the gloss level, and
- Curing of the topcoat by UV irradiation.
In einer Variante des Verfahrens wird die auf der Trägerplatte angeordnete Harzschicht vor dem Auftrag der Primerschicht angeschliffen. Das Anschleifen kann unter Verwendung einer Schleifmaschine mit z.B. einer 80er Körnung erfolgen. Die Körnung der Schleifmaschine ist dabei abhängig von den Eigenschaften (Dicke, Zusammensetzung) der Harzschicht und entsprechend einstellbar. Nach dem Anschleifen kann in einem weiteren Schritt die Reinigung der angeschliffenen Harzschicht mit herkömmlichen Methoden z.B. mit einer Bürste erfolgen.In a variant of the method, the resin layer arranged on the carrier plate is ground before the application of the primer layer. The sanding can be done using a sanding machine with e.g. an 80 grit take place. The grain of the grinding machine is dependent on the properties (thickness, composition) of the resin layer and adjusted accordingly. After sanding, in a further step, the cleaning of the ground resin layer can be carried out by conventional methods, e.g. done with a brush.
Auf die ggf. angeschliffene Harzschicht wird die Primerschicht enthaltend mindestens eine der Silanverbindungen der allgemeinen Formel (I) in einer Menge von 2 bis 20 g/m2, bevorzugt 5 bis 15 g/m2, insbesondere bevorzugt 5 bis 10 g/m2 in flüssiger Form aufgetragen. Als Lösungsmittel sind insbesondere Alkohole, wie Methanol, Ethanol, Propanol und Butanol geeignet.The primer layer containing at least one of the silane compounds of the general formula (I) in an amount of 2 to 20 g / m 2 , preferably 5 to 15 g / m 2 , particularly preferably 5 to 10 g / m 2, is applied to the optionally ground resin layer applied in liquid form. When Solvents are especially suitable alcohols such as methanol, ethanol, propanol and butanol.
Der Auftrag der Primerschicht kann mit einer Walzenauftragsmaschine oder auch mit jeder anderen bekannten Methode erfolgen. Im Anschluss wird die Primerschicht bei Raumtemperatur angetrocknet bzw. abgelüftet. Dieser Vorgang kann durch Verwendung eines IR-Strahlers unterstützt werden.The application of the primer layer can be done with a roll coater or by any other known method. The primer layer is then dried or flashed off at room temperature. This process can be assisted by using an IR emitter.
Auf die Primerschicht wird anschließend die Decklackschicht enthaltend mindestens eine der Silanverbindungen der allgemeinen Formel (II) in einer Menge von 5 bis 30 g/m2, bevorzugt 10 bis 20 g/m2, insbesondere bevorzugt 10 bis 15 g/m2 aufgetragen. Auch im Falle der Decklackschicht haben sich als geeignete Lösungsmittel Alkohole wie Methanol, Ethanol, Propanol und Butanol erwiesen.The topcoat layer containing at least one of the silane compounds of the general formula (II) is then applied to the primer layer in an amount of 5 to 30 g / m 2 , preferably 10 to 20 g / m 2 , particularly preferably 10 to 15 g / m 2 . Also in the case of the topcoat layer have proven to be suitable solvents alcohols such as methanol, ethanol, propanol and butanol.
Der Auftrag der Decklackschicht kann ebenfalls mit Hilfe einer Walzenauftragsmaschine oder anderen bekannten Auftragsverfahren erfolgen.The application of the topcoat can also be done with the aid of a roll coater or other known application methods.
Wie oben erwähnt können der Decklackschicht Nanopartikel zur Einstellung des Glanzgrades in die Decklackschicht eingemischt werden. In Abhängigkeit vom gewünschten Glanz- oder Mattierungsgrad können die Nanopartikel in einer Menge von 5 bis 30 Gew%, bevorzugt 10 bis 20 Gew%, insbesondere bevorzugt 15 Gew% bezogen auf die Decklackschicht zugemischt werden.As mentioned above, the topcoat nanoparticles may be blended into the topcoat layer to adjust the level of gloss. Depending on the desired gloss or degree of matting, the nanoparticles can be mixed in an amount of 5 to 30% by weight, preferably 10 to 20% by weight, particularly preferably 15% by weight, based on the topcoat layer.
Die sich im nächsten Verfahrensschritt anschließende Härtung bzw. Aushärtung der Decklackschicht erfolgt durch UV-Bestrahlung z.B. mit einem Galliumstrahler.The subsequent hardening or curing of the topcoat layer in the next process step takes place by UV irradiation, e.g. with a gallium radiator.
Die vorliegende Werkstoffplatte weist eine Vielzahl von Vorteilen gegenüber den herkömmlichen Werkstoffplatten auf.The present material plate has a number of advantages over the conventional material plates.
So lässt sich durch das nachträgliche Aufbringungen eines sehr dünnen Primers und eines sehr dünnen Decklacks auf eine bereits mit einer Harzschicht (z.B. Melaminharzschicht) versehene Oberfläche einer Holzwerkstoffplatte eine deutlich wärmere und angenehmere Oberfläche erzeugen, wobei die positiven mechanischen Eigenschaften insbesondere einer Melaminharz-Oberfläche beibehalten werden.Thus, by the subsequent application of a very thin primer and a very thin topcoat on a already provided with a resin layer (eg melamine resin layer) surface of a wood-based panel produce a significantly warmer and more pleasant surface, the positive mechanical properties of a particular melamine resin surface are maintained ,
Wie oben erwähnt, kann es ggf. lediglich erforderlich sein, die Harzoberfläche eines fertigen konventionell hergestellten Laminats leicht anzuschleifen.As mentioned above, it may only be necessary to lightly grind the resin surface of a finished, conventionally produced laminate.
Der verwendete Primer enthält in geringer Menge Lösemittel, was aber auf Grund der niedrigen Auftragsmenge akzeptabel ist. Der Decklack ist ein UV-System, welches durch Zugabe von Mattierungsmittel auf verschiedene Glanzgrade eingestellt werden kann.The primer used contains a small amount of solvent, which is acceptable due to the low application rate. The topcoat is a UV system which can be adjusted to different gloss levels by adding matting agents.
Ein weiterer, wesentlicher Nutzen des vorliegenden Verfahrens ist, dass Produkte mit leicht fehlerhaften Harzoberflächen oder nicht mehr verkäuflichen Oberflächen, kostengünstig in neue Produkte umgewandelt werden können.Another key benefit of the present process is that products with slightly defective resin surfaces or non-salable surfaces can be inexpensively converted into new products.
Die Vorteile der vorliegenden Holzwerkstoffplatte lassen sich wie folgt zusammenfassen:
- die technischen Eigenschaften der herkömmlichen Werkstoffplatten wie z.B. der Laminatböden bleiben im Wesentlichen erhalten;
- der maschinentechnische Aufwand zur Bearbeitung der Holzwerkstoffplatten ist moderat;
- die Zusatzkosten für Lackmaterial und Primerschicht sind gering;
- es sind beliebige Glanzgrade einstellbar;
- eine finale Strukturierung der Decklackschicht ist möglich.
- the technical properties of conventional material panels such as the laminate floors are essentially retained;
- the mechanical engineering effort for processing the wood-based panels is moderate;
- the additional costs for paint material and primer layer are low;
- Any degree of gloss can be set;
- a final structuring of the topcoat layer is possible.
Die Erfindung wird nachfolgend unter Bezugnahme auf die Figuren der Zeichnungen an mehreren Ausführungsbeispielen näher erläutert. Es zeigen:
Figur 1- eine perspektivische Ansicht eines Querschnitts einer Holzwerkstoffplatte gemäß einer Ausführungsform.

- a perspective view of a cross section of a wood-based panel according to an embodiment.
Auf der ggf. angeschliffenen Harzschicht 2 ist eine Primerschicht 3 enthaltend mindestens eine Silanverbindung der allgemeinen Formel (I) aufgetragen gefolgt von einer Decklackschicht 4 enthaltend mindestens eine Silanverbindung der allgemeinen Formel (II). In der Decklackschicht 4 können Strukturen 5 eingeprägt sein.On the optionally sanded
Ein Laminatboden-Großformat (2800 mm x 2070 mm) in einer beliebigen Stärke von 6 bis 12 mm mit einer Büttenstruktur, das in der Kurztakt-Presse mit Melaminharz imprägnierten Papieren beschichtet wurde, wird in Zuschnitte (1035 mm x 1400 mm) aufgetrennt. Diese Zuschnitte werden zunächst in einer Lackstrasse mit Hilfe einer Schleifmaschine angeschliffen (mit einer 80er Körnung) und mit einer Bürste gereinigt.A laminate flooring format (2800 mm x 2070 mm) in any thickness of 6 to 12 mm with a laid paper, which has been coated in the short-cycle press with melamine resin impregnated papers, is cut into blanks (1035 mm x 1400 mm). These blanks are first sanded in a paint line using a grinder (with a 80 grit) and cleaned with a brush.
Anschließend wurde in einer Walzenauftragsmaschine ein Primer (Inosil HP17 der Firma Inomat GmbH) in einer Menge von ca. 5 g/m2 (flüssig) aufgetragen. Dieser Primer enthält ein Acidolyseprodukt aus Bis(3-trimethoxysilyl-propyl)amin und p-Toluolsulfonsäure.Subsequently, in a roll coater, a primer (Inosil HP17 from Inomat GmbH) was applied in an amount of about 5 g / m 2 (liquid). This primer contains an acidolysis product of bis (3-trimethoxysilyl-propyl) amine and p-toluenesulfonic acid.
Nach kurzem Ablüften bei Raumtemperatur oder durch einen IR-Strahler unterstützt erfolgt der Auftrag eines Decklacks (Inoflex NI+ der Firma Inomat GmbH) ebenfalls mit Hilfe einer Walzenauftragsmaschine in einer Menge von ca. 10 g/m2 (flüssig). Dieser UV-Lack besteht im Wesentlichen aus einem Reaktions- bzw. Hydrolyseprodukt von Methacryloxypropyltrimethoxysilan (MPTS) und Aminoethylaminopropyltrimethoxysilan.After brief flash-off at room temperature or assisted by an IR radiator, the application of a topcoat (Inoflex NI + from Inomat GmbH) is likewise carried out with the aid of a roll coater in an amount of about 10 g / m 2 (liquid). This UV varnish consists essentially of a reaction or hydrolysis product of methacryloxypropyltrimethoxysilane (MPTS) and aminoethylaminopropyltrimethoxysilane.
Zur Einstellung des Glanzgrades wurde ein Mattierungsmittel (Siloid 244) in einer Menge von etwa 15 Gew.% bezogen auf den Lack zugemischt. Der Lack wird mit Hilfe einer UV-Lampe ausgehärtet (Galliumstrahler, Leistung: 80 Watt/cm).To adjust the gloss level, a matting agent (Siloid 244) in an amount of about 15% by weight, based on the paint, was added. The paint is cured by means of a UV lamp (gallium radiator, power: 80 watts / cm).
An der so lackierten und ausgehärteten Oberfläche wurde ein Gitterschnitttest (DIN EN ISO 2409) durchgeführt. Dabei wurde die Stufe 0 erreicht welche das beste Ergebnis gemäß dieser Prüfung darstellt. Eine Glanzgradmessung (DIN EN ISO 2813; Messwinkel: 85°) ergab im Mittel einen Wert von 3,5. Durch die Variation der Menge des Mattierungsmittels im Decklack sind auch andere Glanzgrade möglich.A crosshatch test (DIN EN ISO 2409) was carried out on the surface painted and cured in this way. In this case, the level 0 was reached which represents the best result according to this test. A gloss measurement (DIN EN ISO 2813, measuring angle: 85 °) averaged a value of 3.5. By varying the amount of matting agent in the topcoat also other gloss levels are possible.
Die Oberfläche fühlte sich beim Anfassen deutlich wärmer und samtiger an als die Ausgangsoberfläche. Die lackierten und ausgehärteten Zuschnitte wurden anschließend in Dielenformate aufgetrennt und an den Kanten Verbindungsprofile angearbeitet und mit Verriegelungsmitteln zum leimlosen Verbinden der Paneele zu einem schwimmend verlegten Fußbodenbelag versehen werden.When touched, the surface felt much warmer and more velvety than the original surface. The lacquered and cured blanks were then cut into plank formats and joined at the edges connecting profiles and provided with locking means for glueless joining of the panels to a floating laid floor covering.
Überraschend zeigt sich, dass keinerlei Aufpoliereffekte in der lackierten Fläche bei einer simulierten Reinigung mit einem weichen Tuch auftraten. Bei der Fräsung der Platten zu Elementen mit Verbindungsprofilen waren keinerlei Lackabsplitterungen im Kantenbereich zu beobachten.Surprisingly, it shows that no polishing effects in the painted surface occurred in a simulated cleaning with a soft cloth. During the milling of the panels to elements with connecting profiles no paint chipping was observed in the edge area.
