Description
Stark strukturierte Oberflächengestaltung für Bauplatte oder Formteil aus kunstharz-gebundener Preßmasse Die vorliegende Anmeldung ist eine Weiterentwicklung meiner Patentanmeldung P 2125453.5 vom 20.5.1971, welche sich mit der Variationsmöglichkeit in der Anwendung verschiedener Füllstoffarten befaßt hat. Hier soll eine Weiterentwicklung beschrieben werden, mit der eine preisgünstige, stark strukturierte Oberflächengestaltung ermöglicht wird. Strongly structured surface design for building panels or molded parts made of synthetic resin-bonded molding compound The present application is a further development my patent application P 2125453.5 from May 20, 1971, which deals with the possibility of variation has dealt with the application of various types of fillers. Here is a further development are described, with which an inexpensive, highly structured surface design is made possible.
Augenblicklich ist ein deutlicher Trend am Baumarkt su strukturierten Flächen erkennbar, wie z.B. im Sichtbeton. Vermehrten Einsatz zeigen auch stark strukturierte Metallgußplatten in Alu, Kupfer oder Bronze, auch wenn sie sehr kostspielig sind und eine nachträgliche Oxydation nicht immer dem Käuferwunsch entspricht.At the moment there is a clear trend in the construction market su structured Areas recognizable, e.g. in exposed concrete. Increased use also show strong textured cast metal plates in aluminum, copper or bronze, even if they are very expensive and subsequent oxidation does not always meet the buyer's wishes.
Bei kunstharzgebundenen Preßspanplatten mit der üblichen Melaminpapierabdeckung sind stärkere Strukturierungen bisher nicht möglich.For resin-bonded chipboard with the usual melamine paper cover stronger structuring are not possible so far.
Mit dem hier beschriebenen Verfahren können den Metallplatten ähnliche Preßplatten mit derselben metallischen Oberflächengestaltung, die z.B. als Haustüreinsätze, als Fassadenelemente, als Wandplatten im Sakralbau oder als Balkoneinfassung Verwendung finden, wobei erhebliche Kosteneinsparungen möglich sind. Hervorzuheben sind außerdem das geringe Gewicht und die Oxydationsfreiheit der metallisierten Oberfläche.With the method described here, the metal plates can be similar Press plates with the same metallic surface design that are used e.g. as house door inserts, Use as facade elements, as wall panels in sacred buildings or as balcony edging where significant cost savings are possible. Also worth highlighting the low weight and the freedom from oxidation of the metallized surface.
Eine witterungsbeständige Oberfläche einer aus Holzfasern und härtbarem Kunstharz als Bindemittel bestehenden Preßplatte wird zusätzlich mit Deckschichten verdichtet. Um die Oberfläche dieser Preßplatte stark strukturieren zu können, müssen Deckschichtmaterialien verwendet werden, die eine starke Verformung beim Preßvorgang mitmachen. Dies wird erreicht durch mehrere Möglichkeiten 1.) Bei Verwendung einer Vliesbahn aus dehnbaren evtl. eingefärbten Fasern, die vor der Pressung mit dem in der Preßmasse enthaltenen Kunstharzbindemittel getränkt werden. Als Unterlage und gleichzeitig als Transportmittel dient eine Trennfolie, bevorzugt aus Polypropylen oder Zellglas. Der Vorteil dieser Oberflächenschicht liegt in der homogenen Verbindung zur Preßmasse.A weather resistant surface one made of wood fiber and hardenable Resin as a binding agent existing press plate is additionally covered with layers condensed. In order to be able to structure the surface of this press plate strongly, must Covering materials are used that have a strong deformation during the pressing process participate. This is achieved in several ways 1.) When using a Nonwoven web made of stretchable, possibly colored fibers, which before pressing with the are soaked in the resin binder contained in the molding compound. As a base and at the same time a release film, preferably made of polypropylene, serves as a means of transport or cellulose glass. The advantage of this surface layer lies in the homogeneous connection to the molding compound.
2.) Die Preßmasse wird mit tiefziehfähiger Metallfolie aus Bluminiun oder Kupfer abgedeckt. Bei Polyesterharz als Bindemittel der Preßmasse muß die Metallfolie zur besseren Bindung mit Haftmittel, bevorzugt Polyurethanharz, versehen werden. Bei Verwendung von Polyurethanharz als Preßmassebindemittel ist kein Haftmittel erforderlich.2.) The molding compound is covered with a deep-drawable metal foil made of Bluminiun or copper covered. In the case of polyester resin as the binding agent for the molding compound, the metal foil must be provided with adhesive, preferably polyurethane resin, for better bonding. When using polyurethane resin as a molding compound, there is no adhesive necessary.
Um dem Preßteil aus Beispiel 1) eine kostbarere Oberfläche zu geben, kann eine nachträgliche Metallisierung stattfinden.In order to give the pressed part from example 1) a more valuable surface, a subsequent metallization can take place.
Ein metallpigmentierter Lack, bevorzugt aus Acryl- oder Polyurethanharz, wird lufgetragen und nach genügender Anhärtung durch tbersprWhen eines patinafarbenen, leicht abwischbaren Farbnebels, patiniert. Durch nochmaliges Übersrühen mit Klarlack wird diese Patina abriebfest auf die Metall-Lackschicht gebunden.A metal pigmented paint, preferably made of acrylic or polyurethane resin, is airborne and, after sufficient hardening, by spraying a patina-colored, easily wipeable paint mist, patinated. By spraying over with clear varnish again this patina is bonded to the metal lacquer layer in an abrasion-proof manner.
Ein nicht unbeachtlicher Vorteil bei der Herstellung dieser stark strukturiarten Preßteile liegt einmal in dem niedrigen, bei ca. 4 kg/cm liegenden Druckbedarf, sodaß primitive Negative aus Preßspanplatten, Formzement o.ä. als Preßunterlage verwendet werden können, zum anderen in der preisgünstigen Erstellung von Mustern und Prototypen eines Artikels bei der Marktanalyse.A not inconsiderable advantage in making this strong Structural pressed parts lies in the low one, which is around 4 kg / cm Pressure requirement, so that primitive negatives made of chipboard, molded cement or similar can be used as a press base can be used, on the other hand, in the inexpensive creation of patterns and prototypes of an article in the market analysis.
