Abstract

The plate has upper, lower and middle layers made from unplastizised-PVC, PVC with polyethylene chlorinates, styrene-containing copolymer or polyacrylate, where one of the layers is different from other two layers in toughness or rigidity or density around 25 percent. Outer layers comprise reinforcement material e.g. layer silicate or glass fibers. Inner layers are made from polyolefin, where the outer layers comprise thickness of 200 micrometers. The outer layers comprise higher toughness than the inner layers.

Description

Der Erfindung liegt die Aufgabe zugrunde, Profilplatten als Dach oder Fassadenelemente aus PVC-U oder Blends aus PVC-U z. B. mit PE-C, SAN, PMMA, ASA oder ABS mit einem PVC-Anteil von mindestens 10% herzustellen, die hinsichtlich ihrer Eigenschaften Steifigkeit und Zähigkeit verbesserte Werte aufweisen oder bei gleichen Eigenschaften reduzierte Flächengewichte zulassen.The invention is based on the object, profile plates as a roof or facade elements made of PVC-U or blends of PVC-U z. B. with PE-C, SAN, PMMA, ASA or ABS with a PVC content of at least 10%, which have improved stiffness and toughness in their properties or allow for the same properties reduced basis weights.

Gelöst wurde die Aufgabe durch einen Schichtverbund mit unterschiedlichen Materialeigenschaften im Kern sowie in den Randbereichen. Beispielsweise können die Randschichten besonders zäh, der Kern hingegen steif eingestellt werden, wodurch die unter Schlagbeanspruchung auftretenden Deformationen besser verteilt werden können. Es resultieren hierbei Profilplatten mit sehr guten Zähigkeiten.The task was solved by a layer composite with different material properties in the core as well as in the border areas. By way of example, the edge layers can be made particularly tough, while the core can be set to be stiff, as a result of which the deformations occurring under impact stress can be better distributed. This results in profile plates with very good toughness.

Es hat sich bereits als vorteilhaft herausgestellt, die Steifigkeit oder Zähigkeit oder Dichte in den Deckschichten im Vergleich zu den Kernschichten um 25%, besonders vorteilhaft um 35% zu verändern.It has already been found to be advantageous to change the stiffness or toughness or density in the cover layers by 25%, particularly advantageously by 35%, compared to the core layers.

Mit der Veränderung der Dichte z. B. durch Aufschäumung der Kernschichten können die Zähigkeit des Verbundes und somit die Hagelschlagresistenz sowie die Steifigkeit und dadurch die zulässige Schneelast bezogen auf das Flächengewicht optimiert werden, zur Verbesserung der absoluten Werte ist meist eine Erhöhung der Wandstärke der Schichtverbund-Profilplatten notwendig.With the change in density z. B. by foaming the core layers, the toughness of the composite and thus the hail resistance and stiffness and thus the permissible snow load based on the basis weight can be optimized to improve the absolute values is usually an increase in the wall thickness of the composite profile plates necessary.

Zur Verbesserung der Steifigkeit der Schichtverbund-Profilplatte ist es möglich, die Randbereiche z. B. mittels Mineralien oder Glasfasern zu versteifen, den Kern hingegen unverstärkt auszuführen. Bei diesem Aufbau können die Verstärkungsstoffe optimal der unter Biegelast auftretenden Randfaserdehnung entgegen wirken, wodurch bei minimalem Einsatz an Verstärkungsmaterialien eine maximale Biegesteifigkeit der Schichtverbund-Profilplatten erreicht wird. Insbesondere gilt dies bei Schichtverbund-Profilplatten mit z. B. durch Schäumung dichtereduziertem Kern. Die Dichtereduktion im Kernbereich der Schichtverbund-Profilplatte kann aber auch durch den Einsatz von Polyolefinen erreicht werden, die mit 0,89 kg/l bis 0,96 kg/l geringere Dichten aufweisen als die Randbereiche aus PVC oder PVC-Blends. Weiterhin ist es möglich, im Kernbereich geschäumte Polyolefine einzusetzen.To improve the rigidity of the composite layer profile plate, it is possible, the edge regions z. B. by means of minerals or glass fibers to stiffen the core, however, perform unreinforced. With this construction, the reinforcing materials can optimally counteract the edge fiber elongation occurring under bending load, whereby a maximum bending stiffness of the laminated composite profiled sheets is achieved with minimal use of reinforcing materials. In particular, this applies to composite layer profile plates with z. B. by foaming density reduced core. However, the density reduction in the core region of the layered composite profile plate can also be achieved by the use of polyolefins which, at 0.89 kg / l to 0.96 kg / l, have lower densities than the edge regions of PVC or PVC blends. Furthermore, it is possible to use foamed polyolefins in the core area.

Beim Einsatz von Polyolefinen im Kernbereich kann es sinnvoll sein, zwischen den Kern- und Randschichten zusätzliche Haftvermittlerschichten zu platzieren, um eine optimale Kraftübertragung zwischen dem Kern und den Deckschichten zu gewährleisten. In diesem Falle besteht die erfindungsgemäße Schichtverbund-Profilplatte aus insgesamt 5 Schichten: Einer Kernschicht sowie zwei Haftvermittler- und zwei Randschichten.When using polyolefins in the core region, it may be useful to place additional adhesion promoter layers between the core and edge layers in order to ensure optimum force transmission between the core and the cover layers. In this case, the composite layer profile plate according to the invention consists of a total of 5 layers: a core layer and two adhesion promoter and two surface layers.

Schichtverbund-Profilplatten sind bekannt. Als Beispiel hierfür kann das Handelsprodukte SALUX-W-Premium genannt werden. Dieses Produkt weist einen Schichtverbund mit einer Grundschicht und gesondert UV-geschützten Deckschicht auf. Durch diesen zweischichtigen Aufbau wird eine besonders gute Witterungsstabilität erreicht, Zähigkeit und Steifigkeit sind durch den zweischichtigen Aufbau aber nicht verbessert.Laminated profiled sheets are known. An example of this is the trade product SALUX-W-Premium. This product has a composite layer with a base coat and a separate UV-protected topcoat. Due to this two-layer structure, a particularly good weathering stability is achieved, but toughness and rigidity are not improved by the two-layer structure.

Auch beim Produkt SALUX WS-Premium handelt es sich um einen Schichtverbund. Hier befindet sich auf einer geschäumten Unterschicht eine geschlossene Deckschicht Die Deckschicht verbessert die Zähigkeit. Da jedoch mindestens eine dritte Funktionsschicht fehlt, ist die Wirkung der Deckschicht auf die Zähigkeit und Steifigkeit begrenzt.The product SALUX WS-Premium is also a layer composite. Here is located on a foamed lower layer a closed top layer The top layer improves the toughness. However, since at least a third functional layer is missing, the effect of the top layer on the toughness and rigidity is limited.

Weiterhin sind z. B. Doppelstegplatten mit beidseitig aufgetragenen UV-Schutzschichten bekannt, die somit aus 3 Schichten aufgebaut sind. Hier beschränkt sich die Funktion lediglich auf den UV-Schutz, Steifigkeit und Zähigkeit werden von solchen Schichten nicht beeinflusst.Furthermore, z. B. double-wall sheets with both sides applied UV protective layers known, which are thus composed of 3 layers. Here, the function is limited only to the UV protection, rigidity and toughness are not affected by such layers.

Es hat sich überaschenderweise herausgestellt, dass sich bei erfindungsgemäßen Verwendung von mindesten 3 Schichten sowohl die zulässige Schneelast (Steifigkeit) als auch der zulässige Hagelkorndurchmesser (Zähigkeit) bei gleichbleibendem Flächengewicht erhöhen lässt, wenn die Schichten sich in der Steifigkeit oder Zähigkeit oder Dichte um mindestens 25% unterscheiden.Surprisingly, it has been found that, when using at least 3 layers according to the invention, both the permissible snow load (rigidity) and the permissible hail grain diameter (toughness) can be increased with a constant basis weight if the layers are at least 25 stiff or toughness or density differ%.

Es hat sich hierbei herausgestellt, dass die beschriebenen Effekte bereits mit bis 200 μm dicken Deck- und Unterschichten, besonders vorteilhaft und ausgeprägt aber bei Deck- und Grundschichten mit Stärken < 120 μm feststellbar sind.It has been found here that the described effects are already detectable with cover layers and sub-layers of up to 200 μm thick, particularly advantageous and pronounced, but with cover layers and base layers with thicknesses <120 μm.
