Description

Die Erfindung betrifft ein Verfahren zur Herstellung von Fußbodenpaneelen und Pressbleche zur Durchführung des Verfahrens auf Kurztaktpressen.The invention relates to a method for producing floor panels and press plates for carrying out the method on short-cycle presses.

Bekannte Fußbodenpaneele weisen auf der im verlegten Zustand oberen Fläche ein Dekor oder ein Dekor mit angepasster Strukturprägung auf, die einen natürlichen Werkstoff, wie beispielsweise Holz oder Stein imitieren.Known floor panels have on the upper surface in the laid state, a decor or decor with an adapted structure embossing, imitating a natural material such as wood or stone.

Als Basisplattenmaterial dienen Holzwerkstoffe wie HDF, MDF oder OSB.Wood base materials such as HDF, MDF or OSB serve as base plate material.

Die Dekore können dabei auf einer Papierlage oder direkt auf die plattenförmige Holzwerkstoffplatte gedruckt vorliegen. Solche Dekore sind beispielsweise Holz- oder Steinimitationen.The decors can be printed on a paper layer or directly on the plate-shaped wood-based panel. Such decors are for example wood or stone imitations.

Wie weiter oben ausgeführt, können die Dekore mit einer strukturgebenden Prägung überlagert werden. Vorzugsweise sind Struktur und Prägung dabei exakt aufeinander abgestimmt, so genannte Synchronpore, um die sichtbaren Flächen optisch und haptisch perfekt an den natürlichen Werkstoff anzunähern. Solche Fußbodenpaneele weisen zunehmend auch umlaufende Fasen auf, die im verlegten Zustand sichtbar bleiben und so genannte V-Fugen ausbilden. Diese umlaufenden Fasen sind jeweils mindestens an gegenüberliegenden Seiten angeordnet und werden zunehmend dekoriert.As explained above, the decors can be superimposed with a structuring imprint. Preferably, structure and embossing are exactly matched to one another, so-called synchronous pores, in order to bring the visible surfaces visually and haptically closer to the natural material. Such floor panels increasingly also have circumferential chamfers, which remain visible in the installed state and form so-called V-joints. These circumferential chamfers are each arranged at least on opposite sides and are increasingly decorated.

Die umlaufenden Fasen sind dazu unifarben ausgeführt oder führen das Dekor der Plattenoberfläche weiter und weisen gegebenenfalls auch eine einfache oder auch eine dekorsynchrone Strukturprägung auf. Damit wird der optische und haptische Eindruck bezüglich eines natürlichen Werkstoffes verstärkt.The circumferential chamfers are executed to solid colors or continue the decor of the plate surface and possibly also have a simple or even a decore-synchronous structure embossing. This enhances the visual and haptic impression of a natural material.

Bei der Herstellung von Laminatfußböden ist es weiterhin bekannt, zur Erhöhung der Authentizität neben optisch ansprechenden Dekoren zunehmend Strukturen auf den Oberflächen einzuprägen. Die Strukturen bei Holzdekoren können einfache Poren sein, aber auch aufwändigere Scraped-Strukturen. Bevorzugt sollten die Strukturen dekorsynchron verlaufen. Ebenso werden auch Stein- oder Marmorfliesen simuliert, bei denen neben der eigentlichen Oberflächenstruktur auch die dekorsynchrone Prägung der Fugenfüllungslinien von Bedeutung ist.In the production of laminate flooring, it is also known to increase the authenticity in addition to visually appealing decors increasingly structures on the surfaces. The structures of wood decors can be simple pores, but also more elaborate scraped structures. The structures should preferably be decorsynchronous. Likewise, stone or marble tiles are also simulated, in which not only the actual surface structure but also the decor-synchronous embossing of the joint filling lines is important.

Verschiedene Ansätze zur Herstellung von strukturierten Fußbodenpaneelen sind bekannt.Various approaches to the manufacture of structured floor panels are known.

So beschreibt FR 2 846 023 ein Pressblech mit zwei nebeneinander angeordneten Prägestempeln, die sich in bestimmten Abständen wiederholen. Mit diesem Pressblech werden Fugen in die Oberfläche von Holzwerkstoffplatten eingefügt.So describes FR 2 846 023 a press plate with two stamping dies arranged side by side, which repeat at certain intervals. With this press plate joints are inserted into the surface of wood-based panels.

Aus der WO 2006/136949 A2 ist ein Verfahren zur Herstellung von Fußbodenpaneelen bekannt, wobei ein Presseelement zum Verpressen der dekorativen Seite der Paneele verwendet wird, welches aus einer Vielzahl von getrennt geformten Pressteilen besteht.From the WO 2006/136949 A2 a method for the production of floor panels is known, wherein a press element for Pressing the decorative side of the panels is used, which consists of a plurality of separately molded pressed parts.

WO 2006/063803 A2 beschreibt ein Fußbodenpaneel mit einer dekorativen Seite, die ein Holzmuster imitiert, wobei dieses Holzmuster Zonen mit unterschiedlichen Glanzgraden umfasst. In die Oberflächenschicht können Prägungen eingefügt werden, die Holzporen imitieren und in Übereinstimmung mit der Holzstruktur sind. WO 2006/063803 A2 describes a floor panel with a decorative side that imitates a wood pattern, this wood pattern comprising zones of different gloss levels. In the surface layer imprints can be inserted, which imitate wood pores and are in accordance with the wood structure.

Bei den weiteren bekannten Verfahren zur Herstellung von Laminatfußböden in Fliesen- oder Dielenstruktur mittels so genannter Kurztaktpressen mit üblichen spezifischen Pressdrucken bis 400 N/cm2 sind bei der Prägung der Fugenfüllungslinien bzw. der Dielenfügung Tiefen von 100 bis 120 Mikrometer, nachfolgend als my angegeben möglich. Die mit den Prägungen versehenen Dekorplatten werden nach Einbringung der Prägung auf die gewünschten Abmessungen zerschnitten, beispielsweise emittierte Dielenbretter auf eine Breite von ca. 160 mm. Die beim Prägen eingesetzten Pressbleche besitzen Erhöhungen entsprechend der gewünschten Prägetiefe und eine Breite von beispielsweise ca. 10 mm. Die Erhöhungen im Pressblech werden so angeordnet, dass der Schnitt zum Abtrennen der einzelnen Dielen bzw. der Fliesen im Bereich der Prägung erfolgt.In the other known methods for the production of laminate flooring in tile or plank structure by means of so-called short-cycle presses with customary specific pressures up to 400 N / cm 2 depths of 100 to 120 microns, hereinafter referred to as my are possible in the stamping of the joint filling lines or the plank insertion , The embossed decorative panels are cut after introduction of the embossing to the desired dimensions, for example, emitted board boards to a width of about 160 mm. The press plates used in embossing have increases corresponding to the desired Embossing depth and a width of, for example, about 10 mm. The elevations in the press plate are arranged in such a way that the cut takes place for separating the individual boards or the tiles in the area of the embossing.

Zur Erzeugung der Fugenfülllinien bzw. Dielenfügung werden bereits dekorierte und oberflächenversiegelte großformatige Platten oder Platten, die mit Dekoren auf einer Papierlage versehen sind, in einer Größe bis zu 2070 X 5600 mm in Kurztaktpressen mittels Prägeblechen bearbeitet. Dabei herrschen Arbeitstemperaturen von 145 bis 180°C gemessen auf der Oberfläche des Werkstückes am Ende der Presszeit bei Arbeitsdrücken von 300 bis 400 N/cm2. Die Taktzeit bei der Bearbeitung der großformatigen Platten beträgt 8 bis 14 s.To produce the joint filling lines or plank joining, already decorated and surface-sealed large-format plates or plates, which are provided with decors on a paper layer, are processed in a size up to 2070 × 5600 mm in short-cycle presses by embossing plates. In this case, working temperatures of 145 to 180 ° C measured on the surface of the workpiece at the end of the pressing time at working pressures of 300 to 400 N / cm 2 . The cycle time for processing the large format plates is 8 to 14 s.

Werden tiefere Strukturen gewünscht, muss die Verweilzeit der Platten in den Kurztaktpressen verlängert werden. Ursache hierfür ist, dass zwar der Temperaturanstieg am Produkt nach dem Schließen der Presse mit der notwendigen Geschwindigkeit erfolgt, in benachbarten Bereichen von Stellen besonderer Prägetiefen und großer Prägeflächen wird jedoch der benötigte Arbeitsdruck innerhalb der Reaktionszeit der Harze nicht erreicht. Um die Reaktionszeit der Harze dem Zeitbedarf bis zum Erreichen des notwendigen Arbeitsdruckes in der Umgebung großer Prägetiefen anzupassen, werden die Presstemperaturen reduziert, was zur Verlängerung der Presszeiten auf ca. 20 bis 40 s oder sogar mehr führt. Solche Verlängerungen der Taktzeiten beim Pressen macht die Herstellung der Dekorplatten schnell unrentabel.If deeper structures are desired, the residence time of the plates in the short-cycle presses must be extended. The reason for this is that although the temperature rise on the product after closing the press at the necessary speed takes place in adjacent areas of points of particular embossing depths and large embossing surfaces, however, the required working pressure within the reaction time of the resins is not achieved. To adjust the reaction time of the resins to the time required to reach the necessary working pressure in the environment of large embossing depths, the pressing temperatures are reduced, which leads to the extension of the pressing times to about 20 to 40 s or even more. Such extensions of the cycle times during pressing makes the production of decorative panels quickly unprofitable.

Wird die Verformungsarbeit und damit der nötige Arbeitsdruck auf der gesamten Produktoberfläche nicht innerhalb der Reaktionszeit (Fließphase der Harze) erreicht, ist der Fluss der Harzmatrix in erhöhten Strukturbereichen auf der Plattenoberfläche nicht mehr ausreichend und führt zu milchigen Verfärbungen und/oder stark porösen Stellen. Diese unerwünschten Fehlbildungen bleiben auch nach dem Verschnitt erhalten. Das erwünschte dekorative Aussehen der Fußbodenpaneele, das Holz oder Stein imitieren soll, ist gestört. Die Oberfläche der Paneele muss durchgängig transparent sein, milchige Verfärbungen und/oder Porositäten führen zu Ausschuss.If the deformation work and thus the required working pressure on the entire product surface is not achieved within the reaction time (flow phase of the resins), the flow of the resin matrix in increased structural areas on the plate surface is no longer sufficient and leads to milky discoloration and / or highly porous areas. These unwanted malformations are retained even after the blending. The desired decorative appearance of the floor panels that imitate wood or stone is disturbed. The surface of the panels must be completely transparent, milky discoloration and / or porosity lead to rejects.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung von Dekorplatten für Fußbodenpaneele zu entwickeln, mit dem auf konventionellen Fertigungsanlagen in üblichen Taktzeiten und mit üblichen Prozessparametern wie Pressdrucken von 400 N/cm2 bzw. 800 N/cm2 Prägestrukturen mit einer Tiefe von bis zu 300 my bzw. 600 my sicher einbringbar sind und dabei der Grad der Ausprägung der Struktur hoch und die Transparenz brillant ist und Pressbleche zur Durchführung des Verfahrens bereitzustellen.The invention has for its object to develop a process for the production of decorative panels for floor panels, with conventional structures in conventional cycle times and conventional process parameters such as pressing pressures of 400 N / cm 2 or 800 N / cm 2 embossed structures with a depth of up to 300 my or 600 my can safely be brought in and the degree of structure of the structure is high and the transparency is brilliant and to provide press plates for carrying out the method.

Erfindungsgemäß wird die Aufgabe durch die Merkmale der Ansprüche 1 sowie 5 gelöst. Besondere Ausgestaltungen finden sich in den Unteransprüchen.According to the invention the object is solved by the features of claims 1 and 5. Particular embodiments can be found in the subclaims.

Erfindungsgemäß bestehen die Prägebereiche auf den Dekorplatten aus schmalen kleinflächigen Bereichen mit Breiten von wenigen mm. Dabei ist einer Zone hohen Drucks, also dem Prägebereich eine Zone geringen Drucks, die genannte Druckentlastungszone, benachbart zugeordnet. Erfindungsgemäß liegt wenigstens eine Zone niedrigen Drucks in solchen Bereichen, die im weiteren Bearbeitungsverlauf als Verschnitt wegfallen. Im Bereich der Verschnittzone wird eine Zone geringen Drucks zwischen zwei schmalen kleinflächigen Bereichen hohen Drucks vorgesehen. Die Anordnung von Zonen hohen Drucks und benachbarte Zonen niedrigen Drucks kann nicht nur in einer Richtung auf der großformatigen Platte vorgesehen sein, sondern auch zusätzlich vorzugsweise in einem Winkel von 90° zur ersten Richtung also auf der Dekorplatte längs und quer.According to the invention, the embossed areas on the decorative panels consist of narrow areas of small areas with widths of a few mm. Here, a zone of high pressure, ie the embossing area, a zone of low pressure, said pressure relief zone, adjacent assigned. According to the invention, there is at least one zone of low pressure in those areas which disappear in the further course of processing as a waste. In the area of the blending zone, a zone of low pressure is provided between two narrow areas of high pressure. The arrangement of zones of high pressure and adjacent zones of low pressure can not be provided in one direction only on the large-format plate, but also in addition preferably at an angle of 90 ° to the first direction so on the decorative plate along and across.

Werden die Dekorplatten nach dem Prägen nicht in einzelne Dielen bzw. Fliesen zerkleinert, sondern immer zu mehreren zusammenhängend weiterverarbeitet, so ist für die Prägung der zusammenhängenden Teile nur eine schmale kleinflächige Zone hohen Drucks notwendig. Die gesamte zusammenhängende Dielen- bzw. Fliesenfläche wirkt in diesem Falle als Zone geringen Drucks.If the decorative panels are not comminuted into individual floorboards or tiles after embossing, but are always further processed into several contiguous ones, then only a narrow, small-area zone of high pressure is necessary for embossing the contiguous parts. The entire contiguous plank or tile surface acts in this case as a zone of low pressure.

Die eingeprägten Vertiefungen können verschiedene Formen aufweisen. Am häufigsten bilden sich dabei L- oder V-förmige Fugen zwischen benachbarten und zu einem Fußbodenbelag verlegten Paneelen in Dielen- oder Fliesenformat aus. Es sind geprägte Vertiefungen anderer Formen ebenfalls möglich.The embossed depressions can have different shapes. The most common form L- or V-shaped joints between adjacent and laid to a floor covering panels in plank or tile format. Embossed depressions of other shapes are also possible.

Die geprägten Vertiefungen sind an den Seitenkanten der Paneele oder innerhalb der von den Seitenkanten eingeschlossenen Paneeloberfläche angeordnet. Weiter optional kann die Form und/oder der Verlauf der geprägten Vertiefungen in einem Paneel auf die Form und/oder den Verlauf der geprägten Vertiefungen im benachbarten Paneel abgestimmt sein. In den zu prägenden Zonen ergeben sich aufgrund der hohen spezifischen Drücke in kurzer Zeit vollständige Ausprägungen und Oberflächenfehler, wie milchige Verfärbungen, werden sicher vermieden.The embossed recesses are located on the side edges of the panels or within the panel surface enclosed by the side edges. Further optionally, the shape and / or the course of the embossed depressions in a panel can be matched to the shape and / or the course of the embossed depressions in the adjacent panel. In the zones to be embossed, due to the high specific pressures, complete characteristics are obtained in a short time and surface defects, such as milky discoloration, are reliably avoided.

Es hat sich überraschend gezeigt, dass es möglich ist, die benachbarte Anordnung von zwei schmalen Prägebereichen im Bereich der nachträglichen Bearbeitungszone mit den üblichen Arbeitsparametern und mit den üblichen Vorrichtungen bei Verwendung großformatiger Platten zu erreichen. Dies stellt einen enormen Kostenvorteil dar.It has surprisingly been found that it is possible to achieve the adjacent arrangement of two narrow embossing areas in the region of the subsequent processing zone with the usual operating parameters and with the usual devices when using large format plates. This represents a huge cost advantage.

Die Anordnung von schmalen Prägebereichen auf dem Pressblech lässt sich in einfacher und ökonomischer Weise in dessen Herstellungsprozess integrieren.The arrangement of narrow embossed areas on the press plate can be integrated into its manufacturing process in a simple and economical manner.

Das beim erfindungsgemäßen Verfahren verwendete Pressblech ist entsprechend des gewünschten Prägeprofils ausgestaltet. So sind im Pressblech in den Zonen der nachträglichen Weiterverarbeitung, die etwa 11 mm breit sind, an beiden Seiten Erhebungen in Form eines Prägestempels in Höhe der Prägetiefe vorgesehen. Sie besitzen eine Breite von etwa 1 mm auf dem ebenen Bereich. Für die Fugenrundung ist eine ähnliche Breite wie für den ebenen Bereich vorgesehen.The press plate used in the method according to the invention is designed according to the desired embossing profile. Thus, in the press plate in the zones of the subsequent processing, which are about 11 mm wide, provided on both sides elevations in the form of a stamping die in the amount of embossing depth. They have a width of about 1 mm on the flat area. For the seam rounding a similar width is intended as for the flat area.

Je nach gewünschtem Glanzgrad in den Fugenrundungen der Fertigprodukte sind die Pressbleche entsprechend bearbeitet. In einer besonderen Ausgestaltung des erfindungsgemäßen Pressbleches weist die Oberfläche in den Rundungen einen niederen Glanzgrad auf, als die Oberfläche über dem herzustellenden Produkt.Depending on the desired degree of gloss in the joint roundings of the finished products, the press plates are processed accordingly. In a particular embodiment of the press plate according to the invention, the surface in the curves on a lower gloss level, as the surface over the product to be produced.
