Die Erfindung betrifft ein Verfahren zur Herstellung von nicht lösbaren, klebstofffreien Verbindungen aus Thermoplast- und Holzwerkstoffen, vorzugsweise in der Möbelindustrie, insbesondere zur Herstellung von Tischplatten mit thermoplastischem, nutzuhgsfreundlich ausgebildetem Schmalflächenprofil, ferner im Innenausbau sowie in der Bauelementenfertigung, vor allem für den Einsatz der Bauteile unter erhöhter anwendungsbezogener Beanspruchung.The invention relates to a process for the preparation of non-releasable, adhesive-free compounds of thermoplastic and wood materials, preferably in the furniture industry, in particular for the production of table tops with thermoplastic, nutzuhgsfreundlich educated narrow profile, also in interior design and in the component manufacturing, especially for the use of Components under increased application-related stress.
Die bekannten Verfahren, bei denen gesondert gefertigte Plastprofile mittels Klebstoffen, ggf. auch unter Zuhilfenahme weiterer Hilfsstoffe, wie z. B. Haftvermittlern, in mehreren Arbeitsgängen mit dem Holzwerkstoff verbunden werden, ergeben bei Anwendung der für eine industrielle Fertigung in Frage kommenden Klebetechnologien keine Verbindung, die hinsichtlich ihrer Verbundfestigkeit erhöhten, insbesondere klimatischen Beanspruchungen genügen kann.The known method in which separately manufactured plastic profiles by means of adhesives, possibly with the aid of other auxiliaries, such. As adhesives are connected in several operations with the wood material, resulting in application of the coming into question for industrial manufacturing adhesive technologies no compound that increased in terms of their bond strength, in particular climatic stress can meet.
In letzter Zeit wurden daher Verfahren entwickelt, mit denen Verbindungen von Plast- mit Holzwerkstoffen in einem Urformprozeß hergestellt werden. Hierzu gehört in erster Linie die Technologie des sog. thermoplastischen Anformens, wie sie in der DD-PS 147220 dargestellt ist. Anwendungsfälle insbesondere zur Herstellung von Platten mit Randleisten, z. B. Tischplatten, sind ferner in der DE-PS 2922568 und in der DD-PS 231 729 offenbart. Die formgebende Kontur wird hierbei durch ein geschlossenes Formwerkzeug gebildet. Abgesehen von der für die Durchführung des Verfahrens benötigten Spritzgießvorrichtung erfordert jede veränderte Abmessung ein neues Formwerkzeug und ist daher mit teuren Investitionen verbunden.Recently, therefore, methods have been developed with which compounds of plastics with wood materials are produced in a primary molding process. These include primarily the technology of so-called. Thermoplastic Anformens, as shown in DD-PS 147220. Use cases in particular for the production of panels with skirting, z. As table tops are also disclosed in DE-PS 2922568 and DD-PS 231 729. The shaping contour is formed here by a closed mold. Apart from the injection molding apparatus required for carrying out the method, each modified dimension requires a new molding tool and is therefore associated with expensive investments.
Ziel der Erfindung ist die rationelle Herstellung von klebstofffreien Verbindungen aus Thermoplast- und Holzwerkstoffen, die auch bei erhöhten klimatischen und anderen Beanspruchungen eine hohe Verbundfestigkeit aufweisen und somit die Gebrauchseigenschaften insbesondere von Möbelbauteilen verbessern.The aim of the invention is the rational production of adhesive-free compounds of thermoplastic and wood-based materials, which have a high bond strength even at elevated climatic and other stresses and thus improve the performance characteristics of furniture components in particular.
Der Erfindung liegt die Aufgabe zugrunde, eine klebstofffreie, hochfeste Thermoplast-Holzwerkstoff-Verbindung zu schaffen, die unter Verzicht auf die Verwendung besonderer geschlossener Formwerkzeuge hergestellt werden kann.The invention has for its object to provide an adhesive-free, high-strength thermoplastic wood-based compound that can be produced waiving the use of special closed molds.
Erfindungsgemäß wird die zu fügende Fläche des Thermoplastwerkstoffs kurzzeitig einseitig partiell ander Oberfläche mindestens bis zum Schmelzpunkt erwärmt, so daß an dieser Oberfläche ein dünner Schmelzefilm entsteht, und sofort anschließend durch Druckelemente an die Fügefläche des Holzwerkstoffes gepreßt.According to the surface to be joined of the thermoplastic material is temporarily heated on one side partially on the other surface at least until the melting point, so that a thin melt film is formed on this surface, and then immediately pressed by pressure elements to the joint surface of the wood material.
Als Thermoplastwerkstoff kann ein entsprechendes Bauteil, Halbzeug oder auch ein thermoplasthaltiges textiles Flächengebilde (Gewebe, Gewirk, Vließ u. dgl.) verwendet werden. Das partielle Aufschmelzen der zu fügenden Fläche geschieht durch unmittelbare Erwärmung, z. B. durch ein elektrisches Heizelement, oder durch einen im Bereich der zu fügenden Fläche des Thermoplastwerkstoffes befindlichen elektrischen Leiter, oder durch mittelbare Erwärmung, z. B. mittels HF-Technik.The thermoplastic material used may be a corresponding component, semifinished product or even a thermoplastic-containing textile fabric (woven fabric, knitted fabric, fleece and the like). The partial melting of the surface to be joined is done by direct heating, z. B. by an electric heating element, or by a located in the region of the surface to be joined of the thermoplastic material electrical conductor, or by indirect heating, for. B. by means of HF technology.
Das Verfahren kann in Abhängigkeit von der Art des Thermoplastteils und der herzustellenden Verbindung kontinuierlich oder diskontinuierlich erfolgen.The process may be continuous or discontinuous, depending on the nature of the thermoplastic part and the compound to be produced.
Während des Anpressens bildet sich im Bereich der Fügeflächen von Plast- und Holzwerkstoff ein Mikroformschluß aus, der ohne Zuhilfenahme von Klebstoff eine hohe Verbundfestigkeit — auch bei erhöhter klimatischer Beanspruchung — garantiert.During pressing, a microforming connection is formed in the area of the joining surfaces of plastic and wood material, which guarantees a high bond strength without the aid of adhesive - even under increased climatic stress.

Figur 1 zeigt ein an seinen Kanten nutzungsfreundlich gestaltetes Thermoplastprofil 1, das sich in geringem Abstand zur Schmalfläche 3 einer Holzwerkstoffplatte 2, hier einer Tischplatte, befindet. Die als Fügefläche 4 vorgesehene Seite des Thermoplastprofils 1 wird durch ein elektrisches Heizelement 5 partiell an der Oberfläche bis kurz über den Schmelzpunkt erwärmt, so daß an der Fügefläche 4 als Voraussetzung für einen erfolgreichen Fügeprozeß ein Schmelzefilm entsteht. Figur 2 zeigt die Holzwerkstoffplatte 2, an die das Thermoplastprofil 1 durch ein Druckelement 6 nach Entfernung des Heizelementes 5 angepreßt wird. Durch den thermoplastischen Schmelzefilm, der beim Anpressen in die Partikelstruktur der Schmalfläche 3 der Holzwerkstoffplatte 2 eindringt und dort erstarrt, entsteht ein Mikroformschluß, der eine sehr hohe Verbundfestigkeit garantiert.Figure 1 shows a useful at its edges designed thermoplastic profile 1, which is located at a small distance to the narrow surface 3 of a wood-based panel 2, here a table top. The intended as joining surface 4 side of the thermoplastic profile 1 is heated by an electric heating element 5 partially on the surface to just above the melting point, so that at the joining surface 4 as a prerequisite for a successful joining process, a melt film is formed. Figure 2 shows the wood-based panel 2, to which the thermoplastic profile 1 is pressed by a pressure element 6 after removal of the heating element 5. Due to the thermoplastic melt film, which penetrates into the particle structure of the narrow surface 3 of the wood-based panel 2 when pressed into place and solidifies there, a microforming connection is created which guarantees a very high bond strength.
Figur 3 zeigt eine Prinzipdarstellung für das klebstofffreie Verbinden eines Thermoplastformteiles 1 in einer Ausnehmung auf der Breitfläche einer Holzwerkstoffplatte 2. Die Fügefläche 4 des Thermoplastformteils 1 wird partiell an der Oberfläche bis kurz über den Schmelzpunkt erwärmt und anschließend sofort auf die Fügefläche 3 in der Ausnehmung auf der Breitfläche der Holzwerkstoffplatte 2 gepreßt. .Figure 3 shows a schematic diagram for the adhesive-free bonding of a thermoplastic molding 1 in a recess on the broad surface of a wood-based panel 2. The joining surface 4 of the thermoplastic molding 1 is partially heated at the surface to just above the melting point and then immediately on the joint surface 3 in the recess the wide surface of the wood-based panel 2 pressed. ,
Figur4 zeigt eine Prinzipdarstellung für ein kontinuierliches Verfahren zur Herstellung einer klebstofffreien Verbindung zwischen einem Thermoplastprofil 1 und allen Schmalflächen einer Holzwerkstoffplatte 2. Dabei wird das Thermoplastprofil 1 fortlaufend in jeweils einem kleinen Bereich der Fügefläche durch ein elektrisches Heizelement 5 bis zum Schmelzpunkt erwärmt und durch das nachfolgende bewegliche Druckelement? sofort an die Schmalfläche der Holzwerkstoffplatte angepreßt, so'daß kontinuierlich alle vier Schmalflächen der Holzwerkstoffplatte 2 mit dem Thermoplastprofil 1 klebstofffrei verbunden werden. Figur 5 zeigt eine Prinzipdarstellung für ein diskontinuierliches Verfahren zur Herstellung einer klebstofffreien Verbindung zwischen einem Thermoplastprofil 1 und einer Schmalfläche 3 einer Holzwerkstoffplatte 2. Das Thermoplastprofil 1, das in seinen Maßen in Länge und Breite mit denen der abzuschließenden Schmalfläche der Holzwerkstoffplatte entspricht, wird gleichzeitig über die gesamte Länge durch βίηΉβϊζβΙβιηβηΐ 5 einseitig partiell an der Oberfläche bis kurz über den Schmelzpunkt erwärmt und nach Entfernen des Heizelementes 5 aus dem Bereich der Fügeflächen an die Schmalfläche der Holzwerkstoffplatte 2 mittels eines Druckelementes 6, das ebenfalls mindestens der Länge der abzuschließenden Schmalfläche entspricht, gepreßt.Figur4 shows a schematic diagram of a continuous process for producing an adhesive-free connection between a thermoplastic profile 1 and all narrow surfaces of a wood-based panel 2. The thermoplastic profile 1 is continuously heated in each case a small area of the joining surface by an electric heating element 5 to the melting point and by the following movable pressure element? Immediately pressed against the narrow surface of the wood-based panel, so'daß continuously all four narrow surfaces of the wood-based panel 2 are connected to the thermoplastic profile 1 adhesive-free. Figure 5 shows a schematic diagram of a discontinuous process for producing an adhesive-free connection between a thermoplastic profile 1 and a narrow surface 3 of a wood-based panel 2. The thermoplastic profile 1, which corresponds in length and width with those of the sealed narrow surface of the wood-based panel in its dimensions, at the same time the entire length by βίηΉβϊζβΙβιηβηΐ 5 partially heated on the surface to just above the melting point and pressed after removal of the heating element 5 from the region of the joining surfaces to the narrow surface of the wood-based panel 2 by means of a pressure element 6, which also corresponds at least to the length of the sealed narrow area ,
