Description

Die Erfindung betrifft ein Bauelement, insbesondere Türblatt, umfassend wenigstens ein Rahmenelement, wobei wenigstens ein Rahmenelement wenigstens einen Falz aufweist sowie wenigstens ein Profilelement, umfassend wenigstens eine Dekorschicht sowie wenigstens eine Funktionsschicht, wobei die Funktionsschicht wenigstens teilweise ein Polyamid, vorzugsweise ein Copolyamid aufweist.The invention relates to a component, in particular a door leaf, comprising at least one frame element, at least one frame element having at least one fold and at least one profile element, comprising at least one decorative layer and at least one functional layer, the functional layer at least partially comprising a polyamide, preferably a copolyamide.

Es ist aus dem Stand der Technik bekannt, dass zum Schutz insbesondere der Stirnflächen derartiger Bauelemente, insbesondere Türblätter, Profilelemente aufgebracht bzw. fixiert werden. Dabei werden an sich bekannte Schmelzklebstoffen eingesetzt, die jedoch dazu führen, dass eine sichtbare Fuge zwischen den Profilelementen und den Bauelementen, insbesondere Türblatt, entsteht, die optisch nicht ansprechend aussieht.
Weiterhin ist es aus dem Stand der Technik bekannt, dass bei Bauelementen, insbesondere Türblättern, insbesondere bei Rahmenelementen mit wenigstens einem Falz das Anbringen, justieren sowie Fixieren der Profilelemente an den jeweiligen Schmalflächen der Rahmenelemente äußerst anspruchsvoll und aufwendig ist. Dies resultiert unter anderem daraus, dass ein Falz eines Rahmenelementes in Längsrichtung etwa orthogonal ausgebildet ist und oft unterschiedliche Falzbreiten bzw. Falztiefen aufweist, was das anbringen und Fixieren der Profilelemente noch zusätzlich erschwert.
Weiterhin schwierig bei den Bauelementen, insbesondere Türblättern, aus dem bekannten Stand der Technik besteht darin, dass beim Einsatz von Rahmenelementen insbesondere aus Holz bzw. Echtholz die bisher eingesetzten Profilelemente mit den bekannten Schmelzklebstoffen nicht zu einer optimalen Fixierung führen und auch die erforderliche Wasserbeständigkeit nicht erreichbar ist.
It is known from the prior art that, in order to protect, in particular, the end faces of such components, in particular door leaves, profile elements are applied or fixed. Known hot melt adhesives are used here, but they result in a visible joint between the profile elements and the components, in particular the door leaf, which does not look visually appealing.
Furthermore, it is known from the prior art that for components, in particular door leaves, in particular for frame elements with at least one fold, the attachment, adjustment and fixing of the profile elements on the respective narrow surfaces of the frame elements is extremely demanding and complex. This results, among other things, from the fact that a fold of a frame element is approximately orthogonal in the longitudinal direction and often has different fold widths or fold depths, which further complicates the attachment and fixing of the profile elements.
Another difficulty with the components, in particular door leaves, from the known prior art is that when frame elements, in particular made of wood or real wood, are used, the profile elements used to date with the known hotmelt adhesives do not lead to optimal fixation and the required water resistance cannot be achieved is.

Aus der EP 1 163 864 ist ein Bauelement, insbesondere eine Möbelplatte und ein Verfahren zu deren Herstellung bekannt. Es wird eine beschrieben, wie ein Profilelement über seine Funktionsschicht mit Holzwerkstoffen durch das Einbringen von Wärme beispielsweise durch den Einsatz der Lasertechnik fixiert werden kann. Zur Fixierung dieses Profilelementes an Bauelementen ist es bei verschiedenen Werkstoffen schwierig, einen sicheren Halt insbesondere des polymeren Profilelementes zu realisieren.From the EP 1 163 864 a component, in particular a furniture panel and a method for their production is known. One describes how a profile element can be fixed via its functional layer with wood-based materials by introducing heat, for example by using laser technology. To fix this profile element on components, it is difficult with various materials to achieve a secure hold, particularly of the polymeric profile element.

Der Erfindung liegt die Aufgabe zugrunde, ein Bauelement, insbesondere Türblatt bereitzustellen, das wirtschaftlich und kostengünstig herstellbar ist, dass bei Rahmenelementen aus Holz insbesondere aus Echtholz, an wenigstens einem Falz wenigstens ein Profilelement optisch ohne Trennfuge fixierbar ist und das im Verbindungsbereich zum Bauelement eine erhöhte Wasserbeständigkeit aufweist.The invention is based on the object of providing a component, in particular a door leaf, which can be produced economically and cost-effectively, that in the case of frame elements made of wood, in particular made of real wood, at least one profile element can be optically fixed to at least one fold without a joint and which increases the connection area to the component Has water resistance.

Um diese Aufgabe zu lösen, stellt die Erfindung ein Bauelement, insbesondere Türblatt, mit den Merkmalen gemäß Anspruch 1 bereit.In order to achieve this object, the invention provides a component, in particular a door leaf, with the features according to claim 1.

Es hat sich überraschend herausgestellt, dass ein Bauelement, insbesondere Türblatt, umfassend wenigstens ein Rahmenelement, wobei wenigstens ein Rahmenelement wenigstens einen Falz aufweist, sowie wenigstens ein Profilelement, umfassend wenigstens eine Dekorschicht sowie wenigstens eine Funktionsschicht, wobei die Funktionsschicht wenigstens teilweise ein Polyamid, vorzugsweise ein Copolyamid aufweist, sich dadurch auszeichnet, dass das Rahmenelement wenigstens teilweise aus Holz, insbesondere Echtholz, umfassend Zellulose, Hemicellulose sowie Lignin, besteht, dass das Profilelement über die Funktionsschicht stoffschlüssig mit wenigstens einem Falz verbunden ist, dass der Werkstoff der Funktionsschicht des Profilelements eine Schmelzviskosität von etwa 50 mPas bis 100 Pas (Pascalsekunden), vorzugsweise von etwa 500 mPas bis 50 Pas, bei 200 °C gemäß ISO 2884 aufweist. Die Erfindung hat erkannt, dass das erfindungsgemäßes Bauelement, insbesondere Türblatt, erst dann wirtschaftlich und kostengünstig herstellbar ist, wenn bei einem Rahmenelement aus Holz, insbesondere Echtholz, ein Profilelement mit einer Funktionsschicht aufweisend wenigstens ein Copolyamid, zum Einsatz kommt, welches eine derart optimale Schmelzviskosität gemäß ISO 2884 aufweist. Nach umfangreichen Versuchen mit verschiedensten Werkstoffen für die Funktionsschicht des Profilelementes hatte sich überraschenderweise herausgestellt, dass nahezu ausschließlich mit einem derartigen Copolyamid- Werkstoff der Funktionsschicht es erstmals möglich ist, eine Falz eines Rahmenelementes eines erfindungsgemäßen Bauelementes, insbesondere Türblatt, optisch ohne Trennfuge wirtschaftlich und kostengünstig zu verschließen, ohne dass die Wasserbeständigkeit des erfindungsgemäßen Bauelementes beeinträchtigt ist. Das Rahmenelement ist dabei eine im Querschnitt etwa mehreckige, beispielsweise viereckige, profilierte Holzleiste in einer definierten Länge, insbesondere eine Echtholzleiste.It has surprisingly been found that a component, in particular a door leaf, comprises at least one frame element, at least one frame element having at least one fold, and at least one profile element, comprising at least one decorative layer and at least one functional layer, the functional layer being at least partially a polyamide, preferably has a copolyamide, characterized in that the frame element consists at least partially of wood, in particular real wood, comprising cellulose, hemicellulose and lignin, that the profile element is cohesively connected to at least one fold via the functional layer, that the material of the functional layer of the profile element is one Melt viscosity of about 50 mPas to 100 Pas (Pascal seconds), preferably from about 500 mPas to 50 Pas, at 200 ° C according to ISO 2884. The invention has recognized that the component according to the invention, in particular the door leaf, can only be produced economically and inexpensively if, in the case of a frame element made of wood, in particular real wood, a profile element with a functional layer having at least one copolyamide is used, which has such an optimal melt viscosity according to ISO 2884. After extensive tests with a wide variety of materials for the functional layer of the profile element, it had surprisingly turned out that, almost exclusively with such a copolyamide material of the functional layer, it was possible for the first time to fold a frame element of a component according to the invention, in particular a door leaf, economically and inexpensively without a joint close without the water resistance of the component according to the invention being impaired. The frame element is an approximately polygonal, for example square, profiled wooden strip with a defined length, in particular a real wooden strip.

Weiterhin vorteilhaft bei dem erfindungsgemäßen Bauelement, insbesondere Türblatt, ist, dass der Werkstoff der Funktionsschicht eine kristalline Dichte ρc von wenigstens 1,13 g/cm3 nach DIN EN ISO 1183-1 (2013-04) aufweist. Durch diese vorteilhafte Ausgestaltung des Werkstoffes der Funktionsschicht des Profilelementes des erfindungsgemäßen Bauelementes verfügt dieser über ausreichend polare Anteile, sodass bei Anbringung des Profilelementes an den wenigstens einen Falz aufweisenden Rahmenelementen der erfindungsgemäßen Bauelemente, insbesondere Türblatt, eine optimierte Haftfestigkeit bzw. Schälfestigkeit bei gleichzeitig besserer Feuchtebeständigkeit realisierbar ist. Der Werkstoff der Funktionsschicht des Profilelementes des erfindungsgemäßen Bauelementes ist in diesen kristallinen Bereichen im Allgemeinen dichter strukturiert als in den sog. amorphen Bereichen. Die kristalline Dichte wird dabei aus dem kristallinen Aufbau berechnet, während die amorphe Dichte experimentell am amorphen Material gemessen wird.Another advantage of the component according to the invention, in particular the door leaf, is that the material of the functional layer has a crystalline density ρ c of at least 1.13 g / cm 3 according to DIN EN ISO 1183-1 (2013-04). As a result of this advantageous embodiment of the material of the functional layer of the profile element of the component according to the invention, the component has sufficient polar proportions so that when the profile element is attached to the frame elements of the components according to the invention which have at least one fold, in particular a door leaf, an optimized adhesive strength or peel strength can be achieved with at the same time better moisture resistance is. The material of the functional layer of the profile element of the component according to the invention is generally more densely structured in these crystalline areas than in the so-called amorphous areas. The crystalline density is calculated from the crystalline structure, while the amorphous density is measured experimentally on the amorphous material.

Ebenfalls vorteilhaft bei dem erfindungsgemäßen Bauelement, insbesondere Türblatt, wird gesehen, dass beim Einsatz eines Profilelementes umfassend eine Funktionsschicht sowie eine mit der Funktionsschicht verbundene Strukturschicht, die beide wenigstens teilweise einen polymeren Werkstoff aufweisen, sich dadurch auszeichnet, dass der Werkstoff der Funktionsschicht ausgewählt ist aus der Gruppe der Polyamide (PA), vorzugsweise eines aliphatischen und / oder teilaromatischen und / oder aromatischen Polyamids, wobei der Werkstoff der Funktionsschicht ein Copolyamid ist, welches ausgehend von Polyamidbildnern, ausgewählt aus der Gruppe, umfassend Caprolactam, Laurinlactam, Aminoundecansäure, Hexamethylendiamin, Adipinsäure, Azelainsäure, Dodecandisäure, Piperazin und dergleichen, hergestellt ist und einen Schmelzflussindex (MFI) von wenigstens 150 g / 10 min., bevorzugt etwa 190 g bis 350 g/ 10 min., besonders bevorzugt 200 g bis 320 g/ 10 min. gemäß DIN ISO 1133 bei 160 °C / 1,20 kg aufweist. Hierdurch ist vorteilhafterweise erreichbar, dass ein derart ausgebildetes Profilelement sehr leicht ohne Klebstoff an den Schmalseiten der Rahmenelemente des erfindungsgemäßen Bauelements, insbesondere Türblatt anbringbar ist, wobei die dafür notwendige Energie zur Aktivierung bzw. zur Überleitung der Funktionsschicht, welche aus einem polymeren Werkstoff besteht, vom festen in einen plastischen bzw. flüssigen Zustand geringer ist als beim bisher bekannten Stand der Technik.Also advantageous in the component according to the invention, in particular the door leaf, is seen that when a profile element comprising a functional layer and a structural layer connected to the functional layer, both of which at least partially have a polymeric material, are used, the material of the functional layer is selected from the group of polyamides (PA), preferably an aliphatic and / or partially aromatic and / or aromatic polyamide, the material of the functional layer being a copolyamide which, starting from polyamide formers, is selected from the group comprising caprolactam, laurolactam, aminoundecanoic acid, hexamethylene diamine, adipic acid , Azelaic acid, dodecanedioic acid, piperazine and the like, and a melt flow index (MFI) of at least 150 g / 10 min., Preferably about 190 g to 350 g / 10 min., Particularly preferably 200 g to 320 g / 10 min. according to DIN ISO 1133 at 160 ° C / 1.20 kg. This advantageously enables a profile element designed in this way to be attached very easily without adhesive to the narrow sides of the frame elements of the component according to the invention, in particular the door leaf, the energy required for activation or for transferring the functional layer, which consists of a polymeric material, from solid in a plastic or liquid state is lower than in the previously known prior art.

Weiterhin vorteilhaft bei der erfindungsgemäßen Kantenleiste ist, dass es durch den Werkstoff der Funktionsschicht des Profilelementes möglich ist, chemische Bindungen, insbesondere Nebenvalenzbindungen sowohl zum Holzwerkstoff des Rahmenelements des erfindungsgemäßen Bauelementes, als auch zu den auf den Flächen des erfindungsgemäßen Bauelements, insbesondere Türblatt, Möbelstück angebrachten Decklagen, beispielsweise aus papierartigen bzw. folienartigen Werkstoffen, zu realisieren, was wiederum eine hohe Haftung zwischen den einzelnen Komponenten im Ergebnis hat..Another advantage of the edge trim according to the invention is that the material of the functional layer of the profile element enables chemical bonds, in particular secondary valence bonds, both to the wood material of the frame element of the inventive element To realize component, as well as to the cover layers attached to the surfaces of the component according to the invention, in particular door leaf, piece of furniture, for example made of paper-like or foil-like materials, which in turn has a high adhesion between the individual components.

Mit dem Werkstoff der Funktionsschicht des Profilelementes ist es somit überraschenderweise erstmals möglich, chemische Bindungen, insbesondere Nebenvalenzbindungen zu allen Werkstoffen der Rahmenelemente des erfindungsgemäßen Bauelements, insbesondere Türblatt, insbesondere auch Wasserstoffbrückenbindungen zu den Deckplatten und/oder Decklagen.With the material of the functional layer of the profile element, it is surprisingly possible for the first time to form chemical bonds, in particular secondary valence bonds, to all materials of the frame elements of the component according to the invention, in particular door leaf, in particular also hydrogen bonds to the cover plates and / or cover layers.

Der Werkstoff der Funktionsschicht des Profilelementes des erfindungsgemäßen Bauelementes, insbesondere Türblatt, kann aber auch kovalente Bindungen, Nebenvalenzbindungen und Wasserstoffbrückenbindungen zu Haftvermittlersystemen insbesondere solchen mit reaktiven Gruppen eingehen. Hierdurch ist es möglich, dass das Profilelement einen optimalen stoffschlüssigen Verbund zur Schmalseite des Bauelements, insbesondere Türblatt, aufweist und somit auch höhere Haftfestigkeitswerte bzw. Schälfestigkeitswerte gemäß DIN 28510 erstmals erreichbar sind.
Ein weiterer Vorteil besteht darin, dass auch eine bessere Adhäsion des Werkstoffes der Funktionsschicht des Profilelementes, insbesondere Türblatt, zu den Decklagen des erfindungsgemäßen Bauelements beispielsweise aus polymeren Werkstoffen wie bspw. PET realisierbar ist. PET ist dabei Polyethylenterephthalat, welches ein durch Polykondensation hergestellter thermoplastischer Kunststoff aus der Familie der Polyester ist.
Ein weiterer Vorteil des erfindungsgemäßen Bauelements besteht darin, dass durch die Ausbildung insbesondere des Werkstoffes der Funktionsschicht für das hergestellte Bauelement bessere bzw. höhere Werte der für Bauelemente wichtigen Feuchtebeständigkeit erstmals realisierbar sind, da die bisherige Schwachstelle im Stand der Technik, nämlich die Verbindung des Werkstoffes der Funktionsschicht mit der auf dem Bauelement aufgebrachten Decklage, wie bspw. CPL- Schichtstoff, HPL- Schichtstoff sowie melamingetränkte Papierwerkstoffe, optimiert ist, indem zumindest Bestandteile des Werkstoffes der Funktionsschicht mit Teilen der Werkstoffe der Decklagen über chemische Bindungen, insbesondere Nebenvalenzbindungen, sowie Wasserstoffbrückenbindungen realisierbar sind, die einerseits für die hohen Haftfestigkeits- bzw. Schälfestigkeitswerte relevant sind und andererseits auch für die besseren bzw. höheren Werte der für Bauelemente wichtigen Feuchtebeständigkeit. CPL- Schichtstoff ist dabei ein "Continuous Pressure Laminate", welche im kontinuierlichen Verfahren aus mehreren Lagen Papier und Harz hergestellt sind. HPL-Schichtstoff ist ein "High Pressure Laminate", welches im Hochdruckpress-Verfahren hergestellt ist in Plattenform aus mehreren Lagen Papier und Harz.
The material of the functional layer of the profile element of the component according to the invention, especially the door leaf, can also form covalent bonds, secondary valence bonds and hydrogen bonds to bonding agent systems, especially those with reactive groups. This makes it possible for the profile element to have an optimal material connection to the narrow side of the component, in particular the door leaf, and thus for the first time also higher adhesive strength or peel strength values according to DIN 28510 can be achieved.
Another advantage is that better adhesion of the material of the functional layer of the profile element, in particular door leaf, to the cover layers of the component according to the invention, for example made of polymeric materials such as PET, can also be achieved. PET is polyethylene terephthalate, which is a thermoplastic made from the polyester family and produced by polycondensation.
Another advantage of the component according to the invention is that the formation of, in particular, the material of the functional layer for the component produced enables better or higher values of the moisture resistance important for components to be achieved for the first time, since the previous weak point in the prior art, namely the connection of the material the functional layer with the top layer applied to the component, such as CPL laminate, HPL laminate and melamine-impregnated paper materials, is optimized by realizing at least components of the material of the functional layer with parts of the materials of the top layers via chemical bonds, in particular secondary valence bonds, as well as hydrogen bonds are relevant on the one hand for the high adhesive strength or peel strength values and on the other hand for the better or higher values of the moisture resistance important for components. CPL laminate is a " Continuous Pressure Laminate ", which in the continuous processes are made from multiple layers of paper and resin. HPL laminate is a " high pressure laminate ", which is produced in the high pressure press process in sheet form from several layers of paper and resin.

Ein weiterer Vorteil besteht darin, dass auch eine bessere Adhäsion des Werkstoffes der Schmelzschicht zu Deckschichten aus polymeren Werkstoffen wie bspw. PET realisierbar ist. PET ist dabei Polyethylenterephthalat, welches ein durch Polykondensation hergestellter thermoplastischer Kunststoff aus der Familie der Polyester ist.A further advantage is that better adhesion of the material of the melt layer to cover layers made of polymeric materials such as PET can also be achieved. PET is polyethylene terephthalate, which is a thermoplastic from the polyester family produced by polycondensation.

Weiterhin vorteilhaft ist, dass auch bei nichtpolymeren Oberflächen der Decklagen des Bauelements, wie beispielsweise mit Farbe beschichtete bzw. lackierte Bauplatten, überraschenderweise für das Profilelement sehr gute Haftfestigkeitswerte bzw. Schälfestigkeitswerte gemäß DIN 28510 messbar sind.It is also advantageous that surprisingly, very good adhesive strength values or peel strength values according to DIN 28510 can also be measured for the profile element, even in the case of non-polymeric surfaces of the top layers of the component, such as building boards coated or painted with paint.

Es hat sich ebenfalls als vorteilhaft herausgestellt, dass der Werkstoff der Funktionsschicht wenigstens ein Copolyamid mit einem Schmelztemperaturbereich von etwa 170 bis 235 °C, vorzugsweise 180 bis 220 °C aufweist. Hierdurch ist es möglich, ein Profilelement für das erfindungsgemäße Bauelement zur Verfügung zu stellen, das einerseits mit einem geringen Eintrag an Energie in die Funktionsschicht mit der Schmalseite des Rahmenelements stoffschlüssig verbindbar ist und das andererseits auch eine wesentlich höhere Haftfestigkeit bzw. Schälfestigkeit an dem erfindungsgemäßen Bauelement, insbesondere Türblatt, aufweist.It has also been found to be advantageous that the material of the functional layer has at least one copolyamide with a melting temperature range of approximately 170 to 235 ° C., preferably 180 to 220 ° C. This makes it possible to provide a profile element for the component according to the invention which, on the one hand, can be cohesively connected to the narrow side of the frame element with a low input of energy into the functional layer, and on the other hand also has a significantly higher adhesive strength or peel strength on the component according to the invention , in particular door leaf.

Insbesondere durch die vorteilhaften Eigenschaften des Werkstoffes der Funktionsschicht des Profilelements des erfindungsgemäßen Bauelements, insbesondere Türblatt, ist dieses sowohl klebstofffrei mit Energie aus einer Energiequelle ausgewählt aus der Gruppe Laserquelle, Infrarotquelle, Ultraschallquelle, Magnetfeldquelle, Mikrowellenquelle, Plasmaquelle sowie Heißluftquelle und dergleichen beaufschlagt zur Bekantung von Möbelstücken einsetzbar.In particular, due to the advantageous properties of the material of the functional layer of the profile element of the component according to the invention, in particular the door leaf, the latter is both adhesive-free and energized from an energy source selected from the group consisting of laser source, infrared source, ultrasound source, magnetic field source, microwave source, plasma source and hot air source and the like for the purpose of edging Pieces of furniture can be used.

Ein weiterer Vorteil der Funktionsschicht des Profilelements des erfindungsgemäßen Bauelements, insbesondere Türblatt, besteht darin, dass der Werkstoff der Funktionsschicht eine Härte Shore A von wenigstens 80 gemäß DIN EN ISO 868 aufweist. Hierdurch ist einerseits die wirtschaftliche und kostengünstige Herstellung der Profilleiste und somit des erfindungsgemäßen Bauelements, insbesondere Türblatt, gewährleistet und andererseits ist es möglich, den Werkstoff der Funktionsschicht des Profilelements den jeweiligen Anforderungen an die zu bekantenden Rahmenelemente des erfindungsgemäßen Bauelements, insbesondere Türblatt, insbesondere solche, die wenigstens einen Falz aufweisen, anzupassen. Weiterhin vorteilhaft ist die damit erreichbare bessere Verarbeitbarkeit bei der Anbringung des Profilelementes an die Schmalseiten /den Rahmenelementen des erfindungsgemäßen Bauelements, insbesondere Türblatt.Another advantage of the functional layer of the profile element of the component according to the invention, in particular the door leaf, is that the material of the functional layer has a Shore A hardness of at least 80 in accordance with DIN EN ISO 868. This on the one hand ensures the economical and inexpensive production of the profile strip and thus of the component according to the invention, in particular the door leaf, and on the other hand it is it is possible to adapt the material of the functional layer of the profile element to the respective requirements for the frame elements of the component according to the invention to be edged, in particular the door leaf, in particular those which have at least one fold. Another advantage is the better processability that can be achieved when the profile element is attached to the narrow sides / the frame elements of the component according to the invention, in particular the door leaf.

Das erfindungsgemäße Bauelement, insbesondere Türblatt, zeichnet sich weiterhin dadurch aus, dass der Werkstoff der Funktionsschicht des Profilelements eine Zugfestigkeit von wenigstens 700 MPa nach DIN EN ISO 527 sowie eine Bruchdehnung von wenigstens 400 % nach DIN EN ISO 527 aufweist.The component according to the invention, in particular the door leaf, is further characterized in that the material of the functional layer of the profile element has a tensile strength of at least 700 MPa according to DIN EN ISO 527 and an elongation at break of at least 400% according to DIN EN ISO 527.

Ebenfalls vorteilhaft bei dem erfindungsgemäßen Bauelement, insbesondere Türblatt, ist, dass der Werkstoff der Funktionsschicht des Profilelementes eine Oberflächenspannung von wenigstens 35 mN/m nach DIN EN 14370 aufweist. Dies führt zu einer verbesserten Adhäsion zu anderen, insbesondere polaren Werkstoffen.It is also advantageous in the component according to the invention, in particular the door leaf, that the material of the functional layer of the profile element has a surface tension of at least 35 mN / m according to DIN EN 14370. This leads to improved adhesion to other, especially polar, materials.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemäßen Bauelements, insbesondere Türblatt, hat sich gezeigt, dass die der Funktionsschicht des Profilelements gegenüberliegend angeordnete Seite der Strukturschicht einer Oberflächenbehandlung durch ein Coronaverfahren, Beflammungsverfahren, Plasmaverfahren, Silikatisierungsverfahren, Silanisierungsverfahren und dergleichen unterworfen wurde. Hierdurch kann ein optimierter Verbund der Funktionsschicht mit der Strukturschicht des Profilelements des erfindungsgemäßen Bauelements, insbesondere Türblatt, für verschiedenste Werkstoffkombinationen insbesondere der Funktionsschicht jederzeit realisiert werden.In a further advantageous embodiment of the component according to the invention, in particular the door leaf, it has been shown that the side of the structural layer located opposite the functional layer of the profile element has been subjected to a surface treatment by a corona process, flame treatment process, plasma process, silication process, silanization process and the like.

Hierdurch ist es möglich, das Profilelement über die Funktionsschicht mit allen derzeit bekannten strahlungsaktivierbaren Verfahren an den Rahmenelementen von Bauelementen, insbesondere Türblatt an, kostengünstig und wirtschaftlich anzubringen. Weiterhin vorteilhaft bei dem erfindungsgemäßen Bauelement, insbesondere Türblatt, ist, dass der Zusatzstoff der Funktionsschicht und/oder der Strukturschicht des Profilelements ausgewählt ist aus der Gruppe der Metalloxide, der Metallphosphate sowie der Metallsalze organischer Anionen.
