Abstract

Layer composite profile plate comprises layers of unplasticized PVC or blends of PVC with chlorinated polyethylene, chlorinated PVC, styrene-containing copolymers and polyacrylates with a PVC content of at least 10%, where the profiled plate is made of at least three functional layers, of which at least one layer differs from the other two layers in density, toughness or stiffness by at least 25%.

Description

Der Erfindung liegt die Aufgabe zugrunde, Profilplatten als Dach oder Fassadenelemente aus PVC-U oder Elends 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 misery 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 a closed top layer on a foamed lower layer. The cover layer improves 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.

Folgende Ausführungsformen sollen beispielhaft aufgeführt werden: Beispiel 1: Profilform: Trapez 70/18 Wandstärke: 1,2 mm Flächengewicht: 1,2 kg/m2 Oberschicht (200 μm): PVC mit Faserrovings (Steifigkeit: 7500 MPa, Dichte 1,48 kg/m2) Haftvermittlerschicht I: Nicht vorhanden Mittelschicht: PVC-Schaum (Steifigkeit: 1200 MPa, Dichte 1,01 kg/m2) Haftvermittlerschicht I: Nicht vorhanden Unterschicht (200 μm): PVC mit Faserrovings (Steifigkeit: 7500 MPa, Dichte 1,48 kg/m2) Zulässige Schneelast: 150 kg/m2 Zulässige Hagelkorngröße: 25 mm The following embodiments are to be given by way of example: Example 1: Profile shape: Trapeze 70/18 Wall thickness: 1.2 mm Basis weight: 1.2 kg / m 2 Upper layer (200 μm): PVC with fiber rovings (Rigidity: 7500 MPa, density 1.48 kg / m 2 ) Adhesive layer I: Unavailable Middle layer: PVC foam (Rigidity: 1200 MPa, density 1.01 kg / m 2 ) Adhesive layer I: Unavailable Undercoat (200 μm): PVC with fiber rovings (Rigidity: 7500 MPa, density 1.48 kg / m 2 ) Permissible snow load: 150 kg / m 2 Permissible hail grain size: 25 mm

Die Ausführung mit Faserrovings in den Randschichten und geschäumtem Kern führt zu einem maximalen Verhältnis von Steifigkeit zum Flächengewicht. Beispiel 2: Profilform: Trapez 70/18 Wandstärke: 1,2 mm Flächengewicht: 1,1 kg/m2 Oberschicht (120 μm): PVC-ASA-Blend (Steifigkeit: 3100 MPa, Dichte 1,31 kg/m2) Haftvermittlerschicht I: Nicht vorhanden Mittelschicht: PVC-Schaum (Steifigkeit: 1200 MPa, Dichte 1,01 kg/m2) Haftvermittlerschicht I: Nicht vorhanden Unterschicht (200 μm): PVC mit Faserrovings (Steifigkeit: 7500 MPa, Dichte 1,48 kg/m2) Zulässige Schneelast: 145 kg/m2 Zulässige Hagelkorngröße: 25 mm The design with fiber rovings in the outer layers and foamed core leads to a maximum ratio of stiffness to basis weight. Example 2: Profile shape: Trapeze 70/18 Wall thickness: 1.2 mm Basis weight: 1.1 kg / m 2 Upper layer (120 μm): PVC ASA blend (Rigidity: 3100 MPa, density 1.31 kg / m 2 ) Adhesive layer I: Unavailable Middle layer: PVC foam (Rigidity: 1200 MPa, density 1.01 kg / m 2 ) Adhesive layer I: Unavailable Undercoat (200 μm): PVC with fiber rovings (Rigidity: 7500 MPa, density 1.48 kg / m 2 ) Permissible snow load: 145 kg / m 2 Permissible hail grain size: 25 mm

Diese Ausführung mit Faserrovings lediglich in der Unterschicht und geschäumtem Kern führt zu höherer Zähigkeit bei geringem Rückgang der zul. Schneelast. Beispiel 3: Profilform: Trapez 70/18 Wandstärke: 1,0 mm Flächengewicht: 1,1 kg/m2 Oberschicht (100 μm): PVC-PMMA-Blend (Steifigkeit: 3400 MPa, Dichte 1,24 kg/m2) Haftvermittlerschicht I: EVA Mittelschicht: PP-Blockcop-Schaum (Steifigkeit: 750 MPa, Dichte 0,62 kg/m2) Haftvermittlerschicht I: EVA Unterschicht (80 μm): PVC-CPE-Blend (Steifigkeit: 2900 MPa, Dichte 1,36 kg/m2) Zulässige Schneelast: 120 kg/m2 Zulässige Hagelkorngröße: 44 mm This version with fiber rovings only in the lower layer and foamed core leads to higher toughness with a small decrease in permissible snow load. Example 3: Profile shape: Trapeze 70/18 Wall thickness: 1.0 mm Basis weight: 1.1 kg / m 2 Upper layer (100 μm): PVC PMMA Blend (Rigidity: 3400 MPa, density 1.24 kg / m 2 ) Adhesive layer I: EVA Middle layer: PP-foam Blockcop (Rigidity: 750 MPa, density 0.62 kg / m 2 ) Adhesive layer I: EVA Undercoat (80 μm): PVC CPE blend (Rigidity: 2900 MPa, density 1.36 kg / m 2 ) Permissible snow load: 120 kg / m 2 Permissible hail grain size: 44 mm

Diese Ausführung mit PVC-PMMA-Blend in der Deckschicht gewährleistet hohe Witterungsstabilität, während der PP-Kern das Flächengewicht reduziert und zusammen mit dem PVC-C-PE-Blend in der Unterschicht und den EVA-Haftvermittlerschichten eine sehr hohe Schlagzähigkeit gewährleistet. Beispiel 4: Profilform: Sinus 76/18 Wandstärke: 1,0 mm Flächengewicht: 1,53 kg/m2 Oberschicht (100 μm): PVC-PMMA-Blend (Steifigkeit: 3500 MPa, Dichte 1,24 kg/m2) Haftvermittlerschicht I: Keine Mittelschicht: PVC-Acrylat (Steifigkeit: 2700 MPa, Dichte 1,31 kg/m2) Haftvermittlerschicht I: Keine Unterschicht (100 μm): PVC-PMMA (Steifigkeit: 3500 MPa, Dichte 1,24 kg/m2) This version with PVC-PMMA blend in the top layer ensures high weathering stability, while the PP core reduces the basis weight and, together with the PVC-C-PE blend in the underlayer and the EVA adhesion promoter layers, ensures very high impact resistance. Example 4: Profile shape: Sine 76/18 Wall thickness: 1.0 mm Basis weight: 1.53 kg / m 2 Upper layer (100 μm): PVC PMMA Blend (Rigidity: 3500 MPa, density 1.24 kg / m 2 ) Adhesive layer I: None Middle layer: PVC-acrylate (Rigidity: 2700 MPa, density 1.31 kg / m 2 ) Adhesive layer I: None Undercoat (100 μm): PVC PMMA (Rigidity: 3500 MPa, density 1.24 kg / m 2 )
