Abstract

The bearer foil is soaked with a duroplastic soaked resin, is provided with a paint coating, and is placed on a workpiece on to which it is pressed. The foil (1) is unwound from a spool (2), and is coated with the paint in a throughflow unit (3). The paint coating is dried in a drier (4) and the coating bearer foil is then wound up again. During the winding-up process, a dividing film (6) is wound with it which is provided with an adhesive layer. The bearer foil is provided with a decor. A polyurethane paint is used, and the paint is hardened by ultraviolet light or by means of electron radiation. USE/ADVANTAGE - Provides profile bodies with a surface protective layer having differing decors and the desired quality.

Description

Die Erfindung betrifft ein Verfahren zur Erzeugung einer Oberflächenschutzschicht auf einem Profilkörper durch Aufbringen einer pigmentierten oder nicht pigmentierten Lackschicht, insbesondere bei der Herstellung von aus einem Gemisch von lignozellulosehaltigen Spänen und einem wärmehärtenden Kunstharz gepreßten Profilkörpern, bei dem aus dem Gemisch erst ein kalt gepreßter Vorpreßling hergestellt wird, welcher anschließend unter hohem Druck und Wärmezufuhr fertiggepreßt wird.The invention relates to a method for generating a Surface protection layer on a profile body by application a pigmented or unpigmented lacquer layer, especially in the manufacture of a mixture of lignocellulosic chips and a thermosetting Resin pressed profiles, in which the mixture only a cold pressed preform is produced, which then pressed under high pressure and heat becomes.

Ein solches Verfahren ist bekannt (EP-A- 156 926). Wenn nach dem bekannten Verfahren große Mengen des Profilkörpers mit dem gleichen Dekor hergestellt werden, dann wird als Dekorschicht eine großtechnisch hergestellte Folie als Ober­ flächenschutzschicht verwendet. Wenn dagegen Profilkörper nur in geringen Stückzahlen mit dem gleichen Dekor hergestellt werden sollen, d. h. mit einer pigmentierten Lackfarbe oder einer nicht pigmentierten Lackfarbe (Klarlack) beschichtet werden sollen, dann werden die Profilkörper mit hochwertigen, vernetzenden Lacken beschichtet, beispielsweise spritzlackiert.Such a method is known (EP-A-156 926). If according to the known method, large amounts of the profile body be made with the same decor, then as Decorative layer is a large-scale film as a top surface protection layer used. If on the other hand profile body only produced in small numbers with the same decor should be d. H. with a pigmented paint color or a non-pigmented paint color (clear coat) coated then the profile body with high quality,  crosslinking varnishes coated, for example spray-painted.

Das bekannte Verfahren ist beim Einsatz für geringe Stückzahlen einerseits aufwendig, weil der Profilkörper erst mit einer Grundierbeschichtung versehen werden muß und erst dann lackiert werden kann. Andererseits treten beim Lackieren größere Verluste des Lackes auf, welches Entsorgungsprobleme verursacht.The known method is used for small quantities on the one hand, complex, because the profile body only with a Primer coating must be provided and only then can be painted. On the other hand, when painting larger losses of the paint on what disposal problems caused.

Das der Erfindung zugrunde liegende technische Problem besteht nun darin, eine andere Lösung für die Erzeugung einer Ober­ flächenschutzschicht anzugeben, welche auch bei kleinen Mengen von mit der gleichen Oberflächenschutzschicht zu versehenden Profilkörpern wirtschaftlich einsetzbar ist und bei welcher die Verluste gegenüber dem bekannten Verfahren stark vermindert sind.The technical problem underlying the invention exists now in it another solution for generating a waiter surface protection layer to specify, even with small quantities with the same surface protection layer Profile bodies can be used economically and in which the Losses greatly reduced compared to the known method are.

Dieses technische Problem ist erfindungsgemäß dadurch gelöst daß eine mit einem duroplastischem Tränkharz getränkte Trägerfolie mit einer Lackschicht versehen, diese auf den Vorpreßling aufgelegt und dieser danach fertiggepreßt wird.This technical problem is solved according to the invention that one soaked with a thermosetting impregnating resin Provide the carrier film with a lacquer layer, this on the Prepress placed and this is then pressed.

Bei Verwendung der erfindungsgemäßen Lösung lassen sich Profilkörper mit einer Oberflächenschutzschicht unterschied­ lichen Dekors und der gewünschten Qualität herstellen.When using the solution according to the invention, Profile body with a surface protection layer differentiated manufacture decor and the desired quality.

Vorteilhafte Einzelheiten der Erfindung sind in den Ansprüchen 2 bis 8 enthalten, welche nachstehend anhand der Figur erläutert wird, welche schematisch eine Vorrichtung zur Herstellung der beschichteten Trägerfolie zeigt.Advantageous details of the invention are in the claims 2 to 8 included, which below with reference to the figure is explained, which schematically shows a device for Production of the coated carrier film shows.

Mit der in der Figur gezeigten Vorrichtung wird die ggf. mit einer zum Lack reaktiven Komponente versehene Trägerfolie mit einem unifarbenen Lack versehen. Dazu wird die Träger­ folie 1 von dem Wickel 2 abgewickelt und in der Durchlauf- Gießanlage 3 gleichmäßig mit dem Lack beschichtet. Bei der Trägerfolie 1 kann es sich beispielsweise um eine mit Melamin­ harz getränkte Papierfolie handeln. Sie kann auch mit einem Haftvermittler zur Verbesserung der Haftung der Lackschicht, beispielsweise einem Acrylat, versehen sein.With the device shown in the figure, the carrier film, optionally provided with a component reactive to the lacquer, is provided with a plain-colored lacquer. For this purpose, the carrier film 1 is unwound from the winding 2 and coated in the continuous casting machine 3 evenly with the paint. The carrier film 1 can, for example, be a paper film impregnated with melamine resin. It can also be provided with an adhesion promoter to improve the adhesion of the lacquer layer, for example an acrylate.

Die mit dem Lack beschichtete Trägerfolie 1 wird in dem Trockner 4 getrocknet. Wenn es sich bei dem Lack um einen durch Wärmezufuhr trocknenden Lack handelt, dann soll beim Trocknen nur so viel Wärme zugeführt werden, daß kein vollständiges Auskondensieren der Trägerfolie erfolgt. Beim Lack kann es sich in diesem Fall um einen Polyurethanlack handeln.The carrier film 1 coated with the lacquer is dried in the dryer 4 . If the lacquer is a lacquer that dries by applying heat, then only so much heat should be supplied during drying that the carrier film does not completely condense out. In this case, the lacquer can be a polyurethane lacquer.

Es können aber auch mittels UV-Licht aushärtende oder elektronenstrahlhärtende Lacke verwendet werden.However, it can also be cured by means of UV light or electron beam curing lacquers can be used.

Die beschichtete Trägerfolie 1 wird auf dem Wickel 5 aufge­ wickelt, der bei Bedarf in ebene Stücke aufgeteilt werden kann. Erforderlichenfalls kann ein Trennfilm 6 mit aufgewickelt werden. Bei dem Trennfilm kann es sich beispielsweise um eine mit einer Trennschicht versehene Papierbahn oder eine Polypropylen-Trennfolie handeln.The coated carrier film 1 is wound up on the winding 5 , which can be divided into flat pieces if necessary. If necessary, a release film 6 can also be wound up. The separating film can, for example, be a paper web provided with a separating layer or a polypropylene separating film.

Wenn die Trägerfolie mit einem Klarlack beschichtet worden ist, dann kann sie dazu verwendet werden, um einen mit Holzdekor­ filmen oder einem anderen Dekorfilm beschichteten Profilkörper mit einer Polyurethan-Klarlackschicht zu versehen. Es ist auch möglich, auf den Profilkörper mittels Siebdruck aufge­ brachte Signets oder Firmenlogos mit einer flächigen UV-Schutzschicht zu versehen.If the carrier film has been coated with a clear varnish, then it can be used to make one with wood decor film or another decorative film coated profile body to be provided with a polyurethane clear coat. It is also possible on the profile body by means of screen printing brought signets or company logos with a flat UV protective layer.
