Description

Die vorliegende Erfindung betrifft ein Verfahren zum Verbinden bzw. Zusammenfügen von thermoplastischen Kunststoffextrudaten in Strang- oder Bandform mit Werkstoffoberflächen zur Erzeugung dreidimensionaler Profile auf der Werkstoffoberfläche sowie die auf diese Weise hergestellten Profile. Ein weiterer Aspekt der vorliegenden Erfindung ist die Herstellung dreidimensional geformter Bilderrahmen durch Extrusion von thermoplastischen Massen auf geeigneten Trägern. Ein anderer Aspekt der vorliegenden Erfindung betrifft die Kantenverfestigung von Werkstoffkanten insbesondere aus Holz.The The present invention relates to a method for connecting or Put together thermoplastic extrudates in strand or ribbon form with material surfaces for producing three-dimensional profiles on the material surface as well the profiles produced in this way. Another aspect of The present invention is the production of three-dimensionally shaped Picture frame by extrusion of thermoplastic materials on suitable Carriers. Another aspect of the present invention relates to edge hardening of material edges, in particular of wood.

Beim Anbringen von sogenannten Kantenbändern (z. B. PVC-Kantenbändern) an die Schmalseiten bzw. Kanten von Holzwerkstücken (z. B. MDF-Platten oder Spanpressplatten) geht man im allgemeinen derart vor, dass man die mit dem Kantenband zu versehende Schmalseite des Werkstückes mit einem Klebstoff versieht und dann das Kantenband darauf befestigt. Bei den üblichen Verfahren des Standes der Technik erfolgt die Herstellung des Kantenbandes unabhängig vom Prozess der Anbringung des Kantenbandes an die Werkstoffkante. Damit sind aber mehrere Nachteile verbunden: Zum einen muss stets eine ausreichende Menge an Kantenband gelagert werden, was zu logistischen Problemen führen kann. Zum anderen kann das Kantenband von seiner Struktur und seinem Profil nicht individuell an die jeweilige Kantenstruktur angepasst werden, weil es sich um ein bereits vorgefertigtes Material handelt, was nicht mehr ohne weiteres verformt werden kann.At the Attaching so-called edge bands (eg PVC edgebands) the narrow sides or edges of wooden workpieces (eg MDF boards or Spanpressplatten) one proceeds in general in such a way that the with the edge band to be provided narrow side of the workpiece with an adhesive and then the edge band attached to it. In the usual Prior art method involves the production of the edge band independently from the process of attaching the edge band to the material edge. But there are several disadvantages: First, always a sufficient amount of edge band are stored, resulting in logistic Cause problems can. On the other hand, the edge band of its structure and its Profile can not be adapted individually to the respective edge structure, because it is a pre-fabricated material, which can not be easily deformed.

Um die zuvor geschilderten Nachteile zu vermeiden, werden in den internationalen Offenlegungsschriften WO 00/53387 A1 und WO 00/53399 A1 , deren gesamter Inhalt hiermit durch Bezugnahme eingeschlossen ist, Vorrichtungen und Verfahren vorgeschlagen, um die Herstellung des auf die Werkstoffoberfläche, insbesondere Werkstoffschmalfläche bzw. -kante, extrudierten Stranges (z. B. Kantenband) einerseits mit der Formgebung und Anbringung andererseits zu kombinieren, d. h. den aus dem Extrusionsprozess kommenden, noch warmen und somit noch formbaren Kunststoffstrang – nach vorheriger Aufbringung eines Klebstoffes auf die zu beschichtende Werkstoffoberfläche – unmittelbar nach seiner Herstellung unter Formgebung mit der Werkstoffoberfläche dauerhaft zu verbinden.In order to avoid the disadvantages described above, in international published patent applications WO 00/53387 A1 and WO 00/53399 A1 , the entire contents of which are incorporated herein by reference, devices and methods proposed to combine the production of the extruded on the material surface, in particular material surface or edge, extruded strand (eg edge band) on the one hand with the shaping and mounting on the other hand, ie the coming from the extrusion process, still warm and thus still malleable plastic strand - after prior application of an adhesive to the material surface to be coated - immediately after its production under molding with the material surface permanently to connect.

So beschreibt die internationale Offenlegungsschrift WO 00/53399 A1 eine Vorrichtung zur Herstellung eines langgestreckten Kunststoffgegenstandes in Form eines extrudierten Stranges, wobei diese Vorrichtung ein Extrusionsmittel zum Extrudieren des Kunststoffstranges sowie ein rotationsfähiges bzw. drehbares Formgebungsmittel, welches eine Formgebung des noch warmen, extrudierten Stranges mit dem gewünschten Querschnittsprofil ermöglicht, umfasst. Bei dem Formgebungsmittel handelt es sich insbesondere um eine Gleit- oder Laufrolle oder mehrere zusammenarbeitende Rollen mit entsprechenden Ausformungen bzw. Profilen für die gewünschte Formgebung. So können das Formgebungsmittel bzw. die Rollen beispielsweise Ausformungen, Vertiefungen oder Vorsprünge aufweisen, um den extrudierten Strängen die gewünschte Form bzw. das gewünschte Profil zu verleihen. Des weiteren kann die Vorrichtung gemäß WO 00/53399 A1 ein Transportmittel für das Werkstück, auf welches der extrudierte Strang aufgebracht werden soll, sowie eine Auftragvorrichtung für einen Klebstoff, mittels dessen das Extrudat auf dem Werkstück fixiert wird, aufweisen. Die dort beschriebenen Verfahren eignen sich insbesondere zum Ankleben von Kantenbändern auf die Schmalseite von Werkstücken insbesondere aus Holz, zur Kantenverfestigung sowie zur Herstellung von Bilderrahmen.This is how the international publication describes WO 00/53399 A1 an apparatus for producing an elongate plastic article in the form of an extruded strand, said device comprising an extrusion means for extruding the plastic strand and a rotatable forming means which permits shaping of the still-hot extruded strand having the desired cross-sectional profile. The shaping means are in particular a sliding or running roller or a plurality of cooperating rollers with corresponding formations or profiles for the desired shaping. For example, the forming means or rollers may include formations, recesses or protrusions to provide the extruded strands with the desired shape or profile. Furthermore, the device according to WO 00/53399 A1 a transport means for the workpiece, on which the extruded strand is to be applied, and an applicator for an adhesive, by means of which the extrudate is fixed on the workpiece have. The methods described there are particularly suitable for adhering edge bands on the narrow side of workpieces, in particular made of wood, for edge hardening and for the production of picture frames.

Des weiteren beschreibt die WO 00/53399 A1 ein Verfahren zur Herstellung eines langgestreckten Kunststoffextrudates, insbesondere in Form eines Stranges, wobei zunächst ein strangförmiges Extrudat aus einem synthetischen Kunststoffmaterial hergestellt wird und dieses Extrudat dann mittels eines rotierbaren bzw. drehbaren Formgebungsmittel, insbesondere einer oder mehrerer Rollen, zu einem Strang, Streifen, Band oder Leiste mit dem gewünschten Querschnittsprofil geformt wird. Die Formgebung erfolgt dabei derart, dass der extrudierte Strang im noch warmen, formbaren Zustand mit der Formgebungsvorrichtung, insbesondere der oder den Rollen, an das Werkstück angedrückt oder angepresst wird. Die Haftung zwischen dem extrudierten Kunststoffstreifen und dem Werkstück wird dabei dadurch bewirkt, dass der Bereich des Werkstoffs, der mit dem geformten Extrudat versehen werden soll, mit einer Klebstoffschicht versehen wird. Auf die zu beschichtende Holzwerkstoff-Schmalfläche muss also zunächst ein Klebstoff aufgetragen werden, damit der anschließend extrudierte thermoplastische Kunststoffstrang eine ausreichende Adhäsion zum Werkstoff, insbesondere Holzwerkstoff, erfährt.Furthermore, the describes WO 00/53399 A1 a process for producing an elongated Kunststofxtrudates, in particular in the form of a strand, wherein initially a rope-shaped extrudate is made of a synthetic plastic material and this extrudate then by means of a rotatable or rotatable shaping means, in particular one or more rollers, into a strand, strip, tape or bar is formed with the desired cross-sectional profile. The shaping takes place in such a way that the extruded strand is pressed or pressed against the workpiece in the still warm, moldable state with the shaping device, in particular the roller (s). The adhesion between the extruded plastic strip and the workpiece is thereby effected by providing the region of the material which is to be provided with the molded extrudate with an adhesive layer. An adhesive must first be applied to the wooden material narrow surface to be coated so that the subsequently extruded thermoplastic plastic strand experiences sufficient adhesion to the material, in particular wood material.

Die internationale Offenlegungsschrift WO 00/53387 A1 beschreibt eine Vorrichtung zur Anbringung eines Kunststoffkantenbandes auf die Kante bzw. Schmalseite eines plattenartigen Werkstoffträgers, z. B. einem Holzbrett oder einer Holzplatte, einer Holzspanplatte, einer Press-Spanplatte oder dergleichen, wobei die Vorrichtung ein Extrusionsmittel zur Extrusion eines Kunststoffstranges auf die Kante bzw. Schmalseite des Werkstoffes und ein Formgebungsmittel, mit dem der extrudierte Kunststoffstrang zu dem gewünschten Profil geformt werden kann, umfasst. Des weiteren kann die Vorrichtung ein Transportmittel für den Transport des Werkstoffes sowie eine Aufbringvorrichtung für den Klebstoff, um den extrudierten Kunststoffstrang mit dem Werkstoff dauerhaft zu verbinden, umfassen. Bei dem Formgebungsmittel handelt es sich insbesondere um eine rotierbare oder drehbare Rolle oder Walze oder mehreren rotierbaren oder drehbaren Rollen oder Walzen, die das Kantenband an die Werkstoffkante andrücken und ihm die gewünschte Form verleihen.The international publication WO 00/53387 A1 describes a device for attaching a plastic edge band on the edge or narrow side of a plate-like material carrier, for. A wood board or a wood board, a chipboard, a pressboard or the like, the device comprising an extrusion means for extruding a plastic strand onto the edge or narrow side of the material and a forming means for forming the extruded plastic strand into the desired profile can, includes. Furthermore, the device can transport a means of transport of the material so such as an adhesive applicator to permanently bond the extruded plastic strand to the material. The shaping means are, in particular, a rotatable or rotatable roller or roller or a plurality of rotatable or rotatable rollers or rollers which press the edge band against the material edge and give it the desired shape.

Des weiteren beschreibt die WO 00/53387 A1 ein entsprechendes Verfahren zur Anbringung des extrudierten Kunststoffkantenbandes auf die Kante bzw. Schmalseite eines platten- bzw. brettartigen Werkstückes durch Extrusion eines Kunststoffstranges direkt auf die Kante des Werkstückes und Formgebung des extrudierten Stranges durch ein Formgebungsmittel, wobei zum dauerhaften Zusammenfügen des Kantenbandes mit dem Werkstoffstück letzteres auf der zu beschichtenden Oberfläche zuvor mit einem Klebstoff beschichtet worden ist, der den Verbund zwischen Kantenband und Werkstoffstück gewährleistet. Als geeignetes Klebstoffsystem nennt die WO 00/53387 A1 hitzeaktivierbare, lösemittelbasierte Polyurethanklebstoffe.Furthermore, the describes WO 00/53387 A1 a corresponding method for attaching the extruded plastic edge band on the edge or narrow side of a plate or board-like workpiece by extrusion of a plastic strand directly on the edge of the workpiece and shaping of the extruded strand by a shaping means, wherein for permanent assembly of the edge strip with the material piece the latter on the surface to be coated has been previously coated with an adhesive that ensures the bond between edge band and piece of material. As a suitable adhesive system calls the WO 00/53387 A1 heat-activated, solvent-based polyurethane adhesives.

Mit den dort genannten Klebstoffsystemen sind aber einige Nachteile verbunden:
Zum einen können solche lösemittelbasierende Systeme aufgrund des Entzündungsrisikos nicht inline mit der Kantenextrusion verwendet werden. Zum anderen verursachen solche lösemittelhaltigen Klebstoffe eine deutliche Belastung der Umwelt mit flüchtigen organischen Stoffen, sogenannten "VOC's", und sind auch für das Produktionspersonal, welches diesen VOC's bei der Produktion ausgesetzt ist, nicht unbedenklich.However, some disadvantages are associated with the adhesive systems mentioned there:
On the one hand, such solvent-based systems can not be used inline with the edge extrusion due to the risk of ignition. On the other hand, such solvent-based adhesives cause significant pollution of the environment with volatile organic compounds, so-called "VOC's", and are also not unobjectionable for the production personnel who are exposed to these VOCs in production.

Die DE 39 37 575 A1 betrifft Sockelleisten mit einem Holzwerkstoffkern und ein Verfahren zu ihrer Herstellung, bei dem die Sockelleiste mit einer Kunststoffaußenschicht beschichtet, vorzugsweise ummantelt ist. Dazu wird auf den Holzwerkstoffkern eine Haftvermittlerschicht aufgebracht, insbesondere eine Schmelzkleberschicht aufextrudiert. Da es sich um eine Vollummantelung der Sockelleisten handelt wird beim Extrudieren der Schmelzkleberschicht ein ringsum geschlossener Kanal erzeugt, wobei der Kanalquerschnitt dem Querschnitt der fertigen Sockelleiste entspricht. Diese Schmelzkleberschicht wird mit einer Außenschicht aus einem thermoplastischen Kunststoff ummantelt.The DE 39 37 575 A1 relates to baseboards with a wood-based material core and a method for their preparation, in which the baseboard is coated with a plastic outer layer, preferably sheathed. For this purpose, a bonding agent layer is applied to the wood-based material core, in particular a melt-adhesive layer is extruded. Since it is a full coating of baseboards when extruding the hot melt adhesive layer, a closed-round channel is generated, the channel cross-section corresponds to the cross section of the finished baseboard. This melt adhesive layer is covered with an outer layer of a thermoplastic material.

Die DE 299 23 700 U1 betrifft lagerstabile, vernetzbare wässrige 1-Komponenten-Dispersionen, die Isocyanate und einen geeigneten Dispersionsklebstoff als Polymerkomponente, z. B. auf Polyurethanbasis, enthalten.The DE 299 23 700 U1 relates to storage-stable, crosslinkable aqueous one-component dispersions containing isocyanates and a suitable dispersion adhesive as a polymer component, for. B. polyurethane-based.

Weiterhin betrifft die DE 199 55 731 A1 einen 2-Komponenten-Schmelzklebstoff mit einer ersten Komponente, die feste Isocyanate aufweist, und einer zweiten Komponente mit einem Katalysator in einer inerten Matrix. Die Verarbeitungstemperaturen des Schmelzklebstoffes liegen im Bereich von 100°C bis 160°C.Furthermore, the concerns DE 199 55 731 A1 a 2-component hot melt adhesive having a first component comprising solid isocyanates and a second component having a catalyst in an inert matrix. The processing temperatures of the hot melt adhesive are in the range of 100 ° C to 160 ° C.

Des weiteren betrifft die WO 00/47687 A1 ein Mehrkomponenten-Beschichtungs- und -Klebstoffmaterial auf Basis von isocyanatterminierten bzw. silanfunktionalisierten Komponenten zum Einsatz in Profilummantelungsanlagen, Beschichtungsanlagen und dergleichen.Furthermore, the concerns WO 00/47687 A1 a multi-component coating and adhesive material based on isocyanate-terminated or silane-functionalized components for use in profile coating systems, coating systems and the like.

Die EP 0 158 068 A1 betrifft einen lösungsmittelfreien Schmelzklebstoff auf Basis von in Methylethylketon unlöslichen Polyesterurethanen, die durch Umsetzung von organischen Diisocyanaten mit vorzugsweise difunktionellen, alkoholische Hydroxylgruppen aufweisenden Polyesterpolyolen und niedermolekularen Diolen als Kettenverlängerungsmittel unter Einhaltung eines spezifischen NCO/OH-Äquivalentverhältnisses erhältlich sind. In diesem Zusammenhang soll der Schmelzklebstoff Polyesterpolyurethane mit einer definierten Menge an eingebauten Carboxylgruppen, Sulfonatgruppen und Urethangruppen enthalten. Der Schmelzklebstoff soll als Haftschicht zur dauerhaften Verbindung von zwei Substraten zur Herstellung flächiger Laminat- bzw. Verbundstrukturen eingesetzt werden.The EP 0 158 068 A1 relates to a solvent-free hotmelt adhesive based on polyester urethanes insoluble in methyl ethyl ketone, which are obtainable by reacting organic diisocyanates with preferably difunctional, alcoholic hydroxyl-containing polyester polyols and low molecular weight diols as chain extenders while maintaining a specific NCO / OH equivalent ratio. In this context, the hotmelt adhesive should contain polyester polyurethanes with a defined amount of incorporated carboxyl groups, sulfonate groups and urethane groups. The hotmelt adhesive is to be used as an adhesive layer for the permanent bonding of two substrates for the production of laminar or composite structures.

Schließlich betrifft die DE 29 05 430 A1 einen Schmelzklebstoff, welcher ein selbsthärtendes, ungesättigtes Polyesterharz mit lufttrocknenden funktionellen Gruppen und einem mittleren Polymerisationsgrad von mindestens acht aufweist und welcher unter Einwirkung von Wärme und Druck abbindet.Finally, the concerns DE 29 05 430 A1 a hot melt adhesive which comprises a self-curing, unsaturated polyester resin having air-drying functional groups and an average degree of polymerization of at least eight and which sets under the action of heat and pressure.

Eine Aufgabe der vorliegenden Erfindung besteht daher in der Bereitstellung eines Verfahrens zur dauerhaften Anbringung extrudierter Kunststoffprofile an Werkstoffoberflächen, welches die zuvor geschilderten Nachteile vermeidet. Insbesondere soll sich ein derartiges Verfahren zur Kantenverfestigung sowie zur Herstellung von Bilderrahmen eignen.A Object of the present invention is therefore in the provision a method for the permanent attachment of extruded plastic profiles on material surfaces, which avoids the disadvantages described above. Especially should such a method for edge hardening as well suitable for the production of picture frames.

Invention is particularly suitable systems have processing temperatures in the range of 160 to 230 ° C, preferably 175-215 ° C (z. B. ® Jowatherm 280.40 or 280.41, marketed by Jowat AG, Germany).

Geeignete anorganische Füllstoffe der zuvor genannten Art werden beispielsweise von der Firma Sphere-Fill, Südafrika, unter der Bezeichnung Plasfill®-5 vertrieben. Besonders bevorzugt ist die Verwendung von anorganischen Füllstoffen auf Basis von Siliciumdioxiden und/oder Aluminiumsilikaten, gegebenenfalls in Mischung mit weiteren anorganischen Oxiden. Der Gehalt von solchen Füllstoffen in der fertigen thermoplastischen Mischung beträgt, wie zuvor geschildert, 30 bis 80 Gew.-%, insbesondere 50 bis 70 Gew.-%.Suitable inorganic fillers of the aforementioned type are sold for example by the company Sphere-Fill, South Africa, under the name Plasfill ® -5. Particularly preferred is the use of inorganic fillers based on silicon dioxides and / or aluminum silicates, optionally mixed with other inorganic oxides. The content of such fillers in the finished thermoplastic mixture is, as described above, 30 to 80 wt .-%, in particular 50 to 70 wt .-%.

Weiterer Gegenstand der vorliegenden Erfindung sind auch Gegenstände bzw. dreidimensionale Profile (z. B. Bilderrahmen oder Leisten), die nach dem erfindungsgemäßen Verfahren hergestellt sind. Die Gegenstände bzw. dreidimensionalen Profile können anschließend noch veredelt sein (z. B. durch Lackierung oder Aufbringung bzw. Ummantelung mit einer dekorativen Folie).Another Subject of the present invention are also objects or three-dimensional profiles (eg picture frames or strips) that according to the inventive method are made. Things or three-dimensional profiles can subsequently be refined (eg by painting or application or Sheathing with a decorative foil).

Außerdem wurde nun überraschenderweise gefunden, dass das zuvor beschriebene Gemisch aus thermoplastischer Masse und anorganischen Füllstoffen sich ausgezeichnet zur Kantenverfestigung eignet. Bei dieser Anwendung geht es um die Verdichtung beispielsweise von Spanplattenschmalflächen bzw. -kanten, so dass diese geglättet werden; eine nachfolgende Ummantelung einer derart ausgerüsteten Spanplatte z. B. mit dekorativen Oberflächenmaterialien ist der typische Verwendungsfall, ohne dass dabei die Holzstruktur der Schmalseite oder Kante auf die Dekorfläche durchgedrückt ("durchtelegraphiert") wird. Insbesondere bei der Verwendung von dünnen Dekorpapieren oder dünnen Dekorfolien kann dann auf die Verwendung einer teureren MDF-Platte verzichtet werden. Das Formulierungsprinzip der thermoplastischen Masse für die Kantenverfestigung ist die gleiche wie bei den Bilderrahmen.In addition, it has now surprisingly been found that the previously described mixture of thermoplastic material and inorganic Fillers are excellent for edge hardening. In this application, it is about the compression of, for example, chipboard narrow surfaces or edges, so that they are smoothed; a subsequent sheathing of such a particleboard equipped z. B. with decorative surface materials is the typical use case, without causing the wood structure of the narrow side or edge of the decorative surface pressed through ("durchtelegraphiert"). In particular, when using thin decorative papers or thin decorative films can then be dispensed with the use of a more expensive MDF board. The formulation principle of the thermoplastic composition for edge hardening is the same as for the picture frames.
