Description

Es ist eine große Anzahl von Oberflächenbeschichtungssystemen bekannt, bei denen die Oberfläche durch eine Lackierung oder Beklebung auf ein fertiges SMC-Produkt aufgebracht wird. Die Nachteile dieser Verfahren liegen im allgemeinen darin, daß sie zum einen durch lange Fertigungszeiten sehr kostenin­ tensiv sind und von der Qualität des verwendeten Klebers abhängig sind und zum anderen eine optimale Haftung auf dem Untergrund nicht immer gewährleistet ist. Ein weiterer Nach­ teil besteht darin, daß an Ecken und Kanten leicht Beschä­ digungen durch mechanische Beanspruchungen (Stöße, Schläge) oder thermisch-physikalisch-chemische Beanspruchung dazu führen, daß die Beschichtung vom Rand her abblättert, abschält oder aufquillt.It is a large number of surface coating systems known in which the surface by painting or Adhesive is applied to a finished SMC product. The disadvantages of these methods are generally that on the one hand they are very expensive due to long production times are intensive and on the quality of the adhesive used are dependent and on the other hand optimal adhesion to the Underground is not always guaranteed. Another after part consists in the fact that there is slight damage to corners and edges damage caused by mechanical stresses (shocks, impacts) or thermal-physical-chemical stress cause the coating to peel off the edge, peel off or swells.

Das in den Patentansprüchen beschriebene Verfahren löst diese Probleme dadurch, daß die Oberfläche eines Produktes während des Herstellungsprozesses durch Einlegen einer entsprechend geeigneten Oberflächenfolie in das Preßwerkzeug entsteht.The method described in the claims solves this Problems in that the surface of a product during of the manufacturing process by inserting one accordingly suitable surface film in the press tool.

Durch willkürlich bedruckte und/oder ausgeschnittene Folien lassen sich beliebige Dessins auf das Produkt unlösbar auf­ bringen. Durch konstruktive Gestaltung des Preßwerkzeuges läßt es sich erreichen, daß die Folie an den Rändern von dem SMC-Material umspült wird (siehe Abb. 1). Diese Umspülung verhindert dauerhaft den oben beschriebenen Ablöseeffekt und ist Hauptanspruch der Patentanmeldung.Arbitrarily printed and / or cut-out foils allow any designs to be applied to the product in an indissoluble manner. By constructing the press tool, it can be achieved that the film is washed around the edges by the SMC material (see Fig. 1). This flushing permanently prevents the detachment effect described above and is the main claim of the patent application.

Durch Auswahl geeigneter Folien lassen sich an der Oberfläche des Produktes besondere Eigenschaften wie z. B. Säurebestän­ digkeit, Abriebfestigkeit, Struktur oder der Glanzgrad unab­ hängig vom Trägermaterial einstellen. By selecting suitable foils you can choose the surface the product has special properties such as B. Acid stock ness, abrasion resistance, structure or degree of gloss depending on the carrier material.
