Verfahren zum Härten von Lacken bzw. Lackfarben auf der Basis ungesättigter Polyester oder Polyurethansysteme auf Holzuntergründen, insbesondere für Möbel. Process for hardening lacquers or lacquer paints based on unsaturated polyester or Polyurethane systems on wooden substrates, in particular for furniture.
Es ist bereits bekannt, Laake entsprechender Rezeptur auf der Basis ungesättigter Polyester durch Ultraviolette-Strahlung zu härten. Bei diesen auch als UV-Polyesterharz be« zeichneten Lacken wird durch die Ultraviolette-Strahlung ein photochemischer Prozeß ausgelöst, durch den die im Polyesterharz und Monomeren enthaltenen Doppelbindungen unter Radikalbindung aufgespaltet werden. Die Aushärtungszeit ist abhängig von der Schichtstärke und der Strahlungsintensität . It is already known that Laake has a corresponding recipe to cure the base of unsaturated polyester by ultraviolet radiation. These can also be used as UV polyester resin Painted paints is caused by the ultraviolet radiation triggered a photochemical process by which the im Polyester resin and monomers containing double bonds are split under radical bonds. The curing time depends on the layer thickness and the radiation intensity.
Durch dieses bekannte Verfahren, bei dem durch Ultraviolette-Strahlung gehärtet wird, konnten jedoch nur farblose Polyester behandelt werden. Auf dem SekVor der pigmentierten Polyester-Lacke war eine Härtung durch Ultraviolette-Strahlung nicht möglich, da Pigmente die Strahlung reflektieren. Auch tendierten die auf diese Weise gehärteten farblosen Polyester-Lacke zum Naohgilben, und zwar insbesondere auf hellen Hölzern und hellen Dekorfolien. Der Einsatz dieae3 bekannten Verfahrens der Aushärtung mit Hilfe von UV-Strahlung ist daher beschränkt.By this known method in which by ultraviolet radiation is cured, however, only colorless polyesters could be treated. On the SekVor the pigmented It was not possible to cure polyester paints with ultraviolet radiation because pigments reflect the radiation. The colorless polyester lacquers hardened in this way also tended to yellow, and in particular to light woods and light decorative foils. The use of the known method of curing with the aid of UV radiation is therefore limited.

Bs wurde bereits versucht, ähnliche Polyester-Lacke durch langwellige Infrarot-Strahlung (Dunkel-Strahler) zu härten. Diese Art der Aushärtung sollte dann eingesetzt werden, wenn die vorstehend genannten Nachteile bei der Aushärtung durch UV-Strahlung nieFt auftreten durften» Die Aushärtungszeit beim Einsatz langwelliger Strahlung ist lang, erfordert also große Bandanlagen und Trockenkanäle.Bs has already been tried to use similar polyester paints to cure long-wave infrared radiation (dark emitters). This type of curing should be used when the above-mentioned disadvantages during curing by UV radiation should never occur »The curing time when using long-wave radiation is long, so it requires large conveyor systems and drying tunnels.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, ein Verfahren der eingangs genannten Art zu schaffen, durch das Polyester-Lacke, -Lackfarbe und Polyurethansysteme schneller ausgehärtet werden»The present invention is based on the object to create a process of the type mentioned above, through the polyester lacquers, lacquer paint and polyurethane systems be cured faster »
Diese Aufgabe wird dadurch gelöst, daß die lacke nach dem Auftragen kurz- bis mittelwelligen Infrarot-Strahlen ausgesetzt werden.This object is achieved in that the paints are exposed to short to medium-wave infrared rays after they have been applied will.
Hierbei wird die überraschende Erkenntnis verwendet, daß die kurz- bis mitte!wellige Infrarot-Strahlung zu keiner Zerstörung oder Beschädigung des beschichteten und damit bestrahlten Werkstoffes führt.The surprising finding is used here that the short to medium wave infrared radiation does not cause any destruction or damage to the coated and thus irradiated material.
Durch das erfindungsgemäße Verfahren erfolgt die Aushärtung durch die kurz- oder mittelwellige Infrarot-Strahlung je nach Art und Schichtstärke in einem Zeitraum von 1 Min» und weniger. Hierdurch ist bedingt, daß die beschichtete und gehärtete Platte sofort nach dem Austritt aus der entsprechenden Vorrichtung, deren Förder.länge im Bereich der Bestrahlung sehr kurz sein kann, unmittelbar einer erneuten Behandlung zugeführt werden kann. Hierbei besteht keine Gefahr, daß die Beschichtung beschädigt wird, so daß es beispielsweise möglich ist, die Platten sofort aufeinander zu stapeln oder eine erst auf einer Seite beschichtete Platte sofort umzudrehen, und auch auf der anderen Seite in der erfindungsgemäßen Weise, zu behandeln»Curing takes place by the method according to the invention through the short or medium wave infrared radiation depending on the type and layer thickness in a period of 1 minute » and less. This means that the coated and hardened plate immediately after exiting the corresponding device, the Förder.länge in the range of Irradiation can be very short, can be immediately re-treated. There is none here There is a risk that the coating will be damaged, so that it is possible, for example, to place the plates on top of one another immediately to stack or immediately turn over a board coated on one side, and also on the other side in the way according to the invention to treat »

Als besonders zweckmäßig hat sich herausgestellt," im Mittelwellen-Bereich der Infrarot-Strahlung zu arbeiten«It has been found to be particularly useful "im Medium wave range of infrared radiation to work "
Bei der Spachtelbeschichtung von Holzspanplatten hat es sich als vorteilhaft herausgestellt, derart zu arbeiten, daß die in einem ersten Arbeitsgang beschichteten Holzspanplatten in an sich bekamt er Weise durch UTtraviolette-Strahlung gehärtet wurden, und in einem zweiten Arbeitsgang mit einem speziellen Polyesterspachtel beschichtet werden, wobei diese Schicht durch kurz- bis mittelwellige Infrarot-Strahlung gehärtet wird βWhen it comes to the spatula coating of chipboard, it has turned out to be the case found to be advantageous to work in such a way that the chipboard coated in a first step in He got himself hardened by ultraviolet radiation and coated with a special polyester spatula in a second step, this layer cured by short to medium wave infrared radiation β
Durch diese kombinierte Arbeitsweise wird vermieden, daß beim Beschichten von uv-gespachtelter Spanplatten mit pigmentiertem Polyesterlack, der mit kura- bzw« mittelwelligen Infrarotstrahlen gehärtet wird, Nachfallerscheinungen durch "Arbeiten" der Späne bzw. Nachhärtung der untersten Polyesterschicht hervorgerufen werden»This combined mode of operation avoids that when coating UV-filled chipboard with pigmented Polyester varnish, which is hardened with short-wave or medium-wave infrared rays, causes after-effects "Working" of the chips or post-hardening of the bottom polyester layer are caused »
