Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Beschichten einer Möbelplatte aus einem Holzwerkstoff gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a method for coating a furniture panel made of a wood material according to the preamble of claim 1.
Aus vielerlei Gründen hat sich die Beschichtung von Möbelplatten aus Holzwerkstoffen, insbesondere in Form von Möbelplatten, mittels Pulverlacken als besonders vorteilhaft herausgestellt. Ein grundsätzliches Problem stellt dabei jedoch die nicht vorhandene oder nur äußerst geringe elektrische Leitfähigkeit des Materials dar, da diese notwendig ist, um die elektrostatische Pulverbeschichtung in entsprechender Qualität durchführen zu können.For many reasons, the coating of furniture panels made of wood-based materials, especially in the form of furniture panels, has proven to be particularly advantageous by means of powder coatings. However, a fundamental problem in this case is the non-existent or only extremely low electrical conductivity of the material, since this is necessary in order to carry out the electrostatic powder coating in the appropriate quality.
Zur Verbesserung der Haftfähigkeit ist es aus der
Das bekannte Verfahren birgt jedoch einige, sowohl die Fertigung wie auch die Qualität der Beschichtung einschränkende Nachteile in sich. Dabei ist in erster Linie zu nennen, dass es durch die Erwärmung des Holzwerkstoffs zu Ausgasungen der innenwohnenden Feuchtigkeit kommen kann, die zu Rissbildungen an den Längs- und Querkanten führt. Diese irreversiblen Schäden treten, wie sich gezeigt hat, bereits bei einer Oberflächentemperatur von 90° Celsius und einer Eindringtiefe der Wärmeenergie von etwa 5 mm auf.However, the known method involves some disadvantages, both manufacturing and the quality of the coating limiting. It should be mentioned in the first place that it can come to the outgassing of the moisture inside by heating the wood material, which leads to cracking at the longitudinal and transverse edges. As has been shown, these irreversible damage already occur at a surface temperature of 90 ° Celsius and a penetration depth of the thermal energy of about 5 mm.
Durch die Infrarotbestrahlung des Pulverlacks, zur Erzielung der Schmelztemperatur, bildet sich zunächst eine äußere, gegenüber der darunter liegenden festere Lackschicht der Schmelze, die dazu führt, dass sich durch die Ausgasungen eine im weitesten Sinn löchrige Oberfläche ergibt, die zumindest den optischen, aber auch den haptischen Eindruck der Beschichtung beeinträchtigt.By the infrared irradiation of the powder coating, to achieve the melting temperature, initially forms an outer, compared to the underlying firmer paint layer of the melt, which causes the outgassing results in the broadest sense holey surface, at least the optical, but also impaired the haptic impression of the coating.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art so weiter zu entwickeln, dass mit geringem konstruktiven Aufwand eine qualitative Verbesserung der Beschichtung möglich ist.The present invention is therefore based on the object, so to develop a method of the generic type that with little design effort, a qualitative improvement of the coating is possible.
Diese Aufgabe wird durch ein Verfahren gelöst, das die Merkmale des Anspruchs 1 aufweist.This object is achieved by a method having the features of claim 1.
Wie sich überraschend gezeigt hat, führt die Koronabehandlung zu einer Verbesserung der Oberflächenspannung der Möbelplatte aus einem Holzwerkstoff, die eine Erhöhung der Adhäsionskräfte zur Folge hat, wodurch der anschließend aufgetragene Pulverlack nicht klebend, sondern elektrostatisch anhaftet. Eine intensive Erwärmung der Werkstoffplatte ist nicht mehr erforderlich.As has surprisingly been found, the corona treatment leads to an improvement in the surface tension of the furniture panel of a wood material, which has an increase in the adhesion forces result, whereby the subsequently applied powder coating not adhesive, but electrostatically adheres. Intensive heating of the material plate is no longer necessary.
Die Koronabehandlung führt zwar ebenfalls zu einer gewissen Erwärmung der Oberfläche der Werkstoffplatte, jedoch erstreckt sich diese Erwärmung nur geringfügig in die Tiefe. Dabei kommt es zur Ausgasung der in diesem Bereich befindlichen Feuchtigkeit, jedoch, im Gegensatz zum Stand der Technik, bevor der Pulverlack aufgebracht wird. Das heißt, bei der nachfolgenden Erhitzung des aufgetragenen Pulverlacks zum Zwecke der Schmelzung mittels Infrarot-Licht sind die wärmebeaufschlagten Bereiche unterhalb der Oberfläche der Platte praktisch feuchtigkeitsfrei. Die sich durch den austretenden Wasserdampf ansonsten ergebende Problematik, nämlich die genannten Lackfehler in Form von Löchern oder anderen Unregelmäßigkeiten, treten nun nicht mehr auf.Although the corona treatment also leads to a certain warming of the surface of the material plate, but this heating extends only slightly in the depth. It comes to the outgassing located in this area Moisture, however, in contrast to the prior art, before the powder coating is applied. That is, in the subsequent heating of the applied powder coating for the purpose of fusion by means of infrared light, the heat-affected areas below the surface of the plate are virtually moisture-free. The otherwise resulting by the exiting water vapor problem, namely the aforementioned paint defects in the form of holes or other irregularities, no longer occur.
Trotzdem wird die für eine erfolgreiche elektrostatische Lackierung mit Pulverlacken notwendige Senkung des Oberflächenwiderstandes erreicht, der < 1010 bis 1011 Ω ist, so dass die Voraussetzungen für eine optimale Beschichtung mit Pulverlack gegeben ist.Nevertheless, the necessary for a successful electrostatic coating with powder coatings lowering the surface resistance is achieved, which is <10 10 to 10 11 Ω, so that the conditions for an optimal coating with powder coating is given.
Das erfindungsgemäße Verfahren führt dazu, dass die Pulverlackierung nun auch ohne Fertigungs- und Qualitätsprobleme im Möbelbereich eingesetzt werden kann, wobei die erzielbaren Ergebnisse hinsichtlich der Oberflächenbeschaffenheit auch höchsten Anforderungen gerecht werden. Bemerkenswert ist darüber hinaus, dass durch die verfahrensbedingte Qualitätsverbesserung die Wirtschaftlichkeit des Verfahrens in signifikanter Weise steigt.The inventive method results in that the powder coating can now be used without manufacturing and quality problems in the furniture sector, the achievable results in terms of surface finish also meet the highest requirements. It is also noteworthy that the procedural quality improvement significantly increases the economic efficiency of the process.
Des weiteren lässt sich das neue Verfahren mit einem geringen apparativen Aufbau realisieren, da Koronabehandlungsanlagen, wie sie bislang für die Erzeugung von Adhäsionskräften an Kunststoffen eingesetzt wurden, durchaus als konfektionierte Vorrichtungen in bestehende Lackieranlagen integriert werden können, ohne dass es wesentlicher konstruktiver Veränderungen bedarf. Dieser Umstand gestattet die Nachrüstung bestehender Beschichtungseinrichtungen, was ebenfalls als ein deutlicher Vorteil anzusehen ist.Furthermore, the new method can be realized with a low apparatus design, since corona treatment plants, as they were previously used for the production of adhesion forces to plastics, can be integrated as ready-made devices in existing paint shops, without the need for significant structural changes. This circumstance allows the retrofitting of existing coating equipment, which is also to be regarded as a clear advantage.
Bezüglich der Qualitätsverbesserung ist anzumerken, dass die Koronaentladung auch in den Kantenbereichen der Möbelplatte mit gleicher Wirkung durchgeführt werden kann wie dies in den flächigen Bereichen der Fall ist, so dass diese Kantenbereiche, die als besonders kritische Bearbeitungszonen angesehen wurden, ebenfalls ohne Qualitätseinbuße mit einem Pulverlack versehen werden können. Insofern ist die Lackierung der Möbelplatte sowohl horizontal wie auch vertikal ausgerichtet möglich, wobei der horizontale Transport einer optimierten Fertigung entgegenkommt.With regard to the quality improvement, it should be noted that the corona discharge can also be carried out in the edge regions of the furniture panel with the same effect as in the flat areas, so that these edge areas, which were considered to be particularly critical processing zones, also without loss of quality with a powder coating can be provided. In this respect, the painting of the furniture panel is aligned both horizontally and vertically possible, whereby the horizontal transport accommodates an optimized production.
Um das Beschichtungsergebnis, das heißt den Pulverlackauftrag, zu optimieren, muß die Oberfläche der Möbelplatte von Handschweiß, Fett oder dergleichen gesäubert werden. Dies erfolgt üblicherweise durch Schleifen. Bei dem erfindungsgemäßen Verfahren jedoch durch die Koronaentladung, wodurch praktisch die zusätzliche Bearbeitung unterbleiben kann. Vorstehende Holzfasern, deren Größe sich im Mikrobereich bemisst, werden durch die bei der Koronaentladung entstehende Entladungsflamme abgebrannt, bzw. weggesprengt, so dass danach die Oberfläche als feinst gesäubert bezeichnet werden kann.In order to optimize the coating result, that is the powder coating order, the surface of the furniture panel must be cleaned of hand sweat, grease or the like. This is usually done by grinding. In the method according to the invention, however, by the corona discharge, which practically can be omitted, the additional processing. Projecting wood fibers, the size of which is measured in the micro range, are burned off or blown away by the discharge flame produced during the corona discharge, so that afterwards the surface can be described as finely cleaned.
Im horizontalen Durchlauf erfolgt die Koronabehandlung und anschließend die Pulverbeschichtung einer ersten Seite der Möbelplatte, beispielsweise der Vorderseite sowie der umfänglichen Kanten. Bei der rückseitigen Behandlung der Möbelplatte in diesem Sinn wird die zuvor beschichtete Kante einer weiteren Koronaentladung unterzogen, so dass diese Kante für die Anhaftung der folgenden und somit sozusagen zweiten Schicht in gewünschter Weise präpariert ist.In the horizontal pass, the corona treatment and then the powder coating of a first side of the furniture panel, for example, the front and the peripheral edges. In the back treatment of the furniture panel in this sense, the previously coated edge is subjected to a further corona discharge, so that this edge is prepared for the adhesion of the following and thus, so to speak second layer in the desired manner.
Eine zweite Beschichtung der Oberflächen der Möbelplatte insgesamt kann für den Fall vorgesehen sein, dass die Pulverlackierung des ersten Auftrags nicht dem geforderten Qualitätsstandards entspricht, wobei durch Nachbearbeitung beispielsweise kleine Pickel oder Pusteln entfernt, vorhandene Löcher angeschliffen und einfache Farbunreinheiten beseitig werden. Danach wird die Möbelplatte nochmals dem erfindungsgemäßen Verfahren unterzogen.A second coating of the surfaces of the furniture panel as a whole may be provided in the event that the powder coating of the first order does not meet the required quality standards, with by post processing, for example, small pimples or pimples removed, existing holes sanded and simple color impurities are eliminated. Thereafter, the furniture panel is subjected to the process of the invention again.
Gegenüber dem Stand der Technik, bei dem solche beschädigten Teile auch durch Nacharbeit nicht in dem gewünschten und geforderten Maße qualitativ wieder herstellbar sind, bietet die Erfindung erhebliche Kostenvorteile, da praktisch ausschussfrei gearbeitet werden kann.Compared to the prior art, in which such damaged parts can not be reproduced qualitatively by reworking in the desired and required dimensions, the invention offers considerable cost advantages, since it can be worked practically without jerking.
Prinzipiell kann auf eine erste Pulverbeschichtung im Sinne der Erfindung eine zweite Beschichtung erfolgen, das heißt, die bereits pulverlackierte Oberfläche der Möbelplatte wird ebenfalls einer Koronabehandlung unterzogen und anschließend eine zweite Pulverschicht aufgebracht.In principle, on a first powder coating in the context of the invention, a second coating can take place, that is, the already powder-coated surface of the Furniture panel is also subjected to a corona treatment and then applied a second layer of powder.
Dies kann unter Umständen dann sinnvoll sein, wenn, wie nach einem weiteren Gedanken der Erfindung vorgesehen, die Koronaentladung unter Einbringung eines Aerosols in die Entladungszone erfolgt. Wie sich gezeigt hat, ist eine Koronaentladung unter diesen Bedingungen besonders effektiv.Under certain circumstances, this can be useful if, as provided according to a further aspect of the invention, the corona discharge takes place with the introduction of an aerosol into the discharge zone. As it has been shown, corona discharge under these conditions is particularly effective.
Da es möglicherweise durch das Einbringen der Aerosole zu einer Veränderung der Oberflächenausbildung beim Pulverbeschichten kommen kann, insbesondere durch eine feuchtigkeitsbedingte Holz-Faseraufrichtung, kann ein zweiter Verfahrensdurchlauf sinnvoll sein.Since it may possibly be due to the introduction of the aerosols to a change in surface formation during powder coating, in particular by a moisture-related wood fiber orientation, a second process cycle may be useful.
Neben dem genannten Pulverlack, der durch UV-Strahlung aushärtbar ist, kann auch ein sogenanntes Niedertemperatur-Pulver zum Einsatz kommen.In addition to the said powder coating, which is curable by UV radiation, a so-called low-temperature powder can be used.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.
Eine Vorrichtung zur Durchführung des Verfahrens wird nachfolgend anhand der beigefügten Zeichnung beschrieben.An apparatus for carrying out the method will be described below with reference to the accompanying drawings.
Die einzige Figur zeigt schematisch eine Vorrichtung zum Beschichten einer Möbelplatte in einer perspektivischen Ansicht.The single figure shows schematically a device for coating a furniture panel in a perspective view.
In der Figur ist eine Vorrichtung zum Beschichten einer Möbelplatte aus einem Holzwerkstoff mit Pulverlack dargestellt, wobei die Möbelplatte insgesamt mit dem Bezugszeichen 1 versehen ist.In the figure, a device for coating a furniture panel made of a wood material with powder coating is shown, wherein the furniture panel is provided with the reference numeral 1 as a whole.
Die Möbelplatte 1 wird liegend mittels eines Transportbandes 2 unter dem gegenüber ortsfesten Bearbeitungsstationen hindurchgeführt, wobei in der Folge der Bearbeitungsschritte als erstes eine Einrichtung zur Koronabehandlung 3, nachfolgend eine Beschichtungsanlage 4 sowie eine Härteeinrichtung angeordnet sind.The furniture panel 1 is guided horizontally by means of a conveyor belt 2 under the opposite stationary processing stations, wherein in the sequence of processing steps, first a device for corona treatment 3, followed by a coating system 4 and a curing device are arranged.
Vor einer Beschichtung der plattenförmigen Möbelplatte 1 mit einem Pulverlack mittels der Beschichtungseinrichtung 4 erfolgt durch die Einrichtung zur Koronabehandlung 3 eine Koronaentladung auf der Oberfläche der den Wirkbereich der Einrichtung 3 durchlaufenden Möbelplatte 1.Before the coating of the plate-shaped furniture panel 1 with a powder coating by means of the coating device 4 is carried out by the device for corona treatment 3, a corona discharge on the surface of the effective range of the device 3 continuous furniture panel. 1
Auf die so vorbereitete Oberfläche der Möbelplatte 1 wird mit Hilfe der Beschichtungseinrichtung 4 der Pulverlack aufgetragen. In der nachfolgenden Härteeinrichtung 5 wird zunächst der aufgetragene Pulverlack mittels Infrarot-Bestrahlung geschmolzen, so dass sich eine sehr glatte, geschlossene Lack-Beschichtung ergibt, die anschließend durch ultraviolettes Licht ausgehärtet wird.On the thus prepared surface of the furniture panel 1, the powder coating is applied by means of the coating device 4. In the subsequent hardening device 5, first of all the applied powder coating is melted by means of infrared irradiation, so that a very smooth, closed paint coating results, which is then cured by ultraviolet light.
Eine nicht dargestellte Wendeeinrichtung kann sich anschließen, so dass die Möbelplatte 1 so gedreht und abgelegt wird, dass die bis dahin unbehandelte Seite ebenfalls im vorbeschriebenen Sinn bearbeitet werden kann.An unillustrated turning device may follow, so that the furniture panel 1 is rotated and stored so that the hitherto untreated side can also be processed in the above sense.
