Description
benötigten Klöpperböden noch möglich ist.required dished ends is still possible.
Der Einsatz des Faservlieses aus thermoplastischem Polyester bewirkt ferner, daß der große Wärmeausdehnungskoeffizient von PVDF, der im Bereich von 15 bis 10 X 10"5 je Grad Celsius !legt, sich bei einem Verbund mit einer festen Unterlage, deren Material einen erheblich von dem PVDF abweichenden Wärmeausdehnungskoeffizienten aufweist (z. B. Stahl), nicht nachteilig auswirken kann. Das dehnungsfähige Polyeste-faservlies fängt nämlich die unterschiedlichen Dehnungen auf.The use of the fiber fleece made of thermoplastic polyester also has the effect that the large coefficient of thermal expansion of PVDF, which is in the range of 15 to 10 X 10 " 5 per degree Celsius! has a different coefficient of thermal expansion (e.g. steel), cannot have a disadvantageous effect, because the stretchable polyester fiber fleece absorbs the different expansions.
Als thermoplastische Polyester kommen insbesondere lineare Polyester auf Basis von Polyäthylenterephthalat in Frage. Die Vliese werden beispielsweise durch Vernadeln von Polyesterstapelfasern hergestellt. Derartige Vliese weisen eine hohe Festigkeit bei gleichzeitig guter Dehnung auf. Sie besitzen eine weitgehend strukturfreie Oberfläche.Linear polyesters based on polyethylene terephthalate are particularly suitable as thermoplastic polyesters in question. The nonwovens are produced, for example, by needling polyester staple fibers. Such nonwovens have high strength and good elongation at the same time. You own one largely structure-free surface.
Es folgt die Beschreibung eines Aüsführungsbeispiels der Erfindung anhand der Zeichnung. Es zeigtThe following is a description of an exemplary embodiment of the invention with reference to the drawing. It shows
Fig. 1 schematisch das Kaaschieren einer PVDF-Bahn mit textilem Flächengebilde undFig. 1 shows schematically the lamination of a PVDF web with a textile fabric and
Fig. 2 den prinzipiellen Aufbau des Verbundkörpers. 2 shows the basic structure of the composite body.
Auf eine Oberfläche einer frisch aus dem Extruder 1 extrudierten Polyvinylidenfluorid-Bahn 2, dit sich noch im plastischen Zustand bei beis, uelsweise 190° C befindet, wird direkt nach Verlassen des Extruders von der Vorratsrolle 4 kommend das Polyestervlies 3, ein Andruckwalzenpaar 5 durchlaufend aufgebracht. Hierbei drückt sich das Polyestervlies 3 so in die Oberfläche der Bahn 2 ein, daß in der Wärme eine homogene Verbindung entsteht und es außerdem darin nach Erkalten mechanisch fest verankert wird. Der Verbundkörper 6 wird dann der weiteren Verarbeitung, wie Konfektionierung etc., zugeführt.On a surface of a freshly extruded from the extruder 1 polyvinylidene fluoride web 2, dit is still in its plastic state at both times 190 ° C is, the polyester fleece coming from the supply roll 4 immediately after leaving the extruder 3, a pair of pressure rollers 5 applied continuously. The polyester fleece 3 is pressed here so into the surface of the web 2 that a homogeneous connection is created in the heat and it also is mechanically firmly anchored in it after cooling. The composite body 6 is then subjected to further processing, such as packaging, etc., supplied.
In der Fig. 2 ist schematisch die Verbundplatte 6 bestehend aus der PVDF-Platte 2 und dem Polyestervlies 3, die homogen miteinander verbunden sind, dargestellt. Diese Verbundplatte 6 kann beispielsweise als Halbzeug für den Behälterbau dienen und kann beispielsweise mit glasfaserarmierten ungesättigten Polyesterharzen auf der Polyestervliesseite 3 aufbauend verstärkt werden.In Fig. 2, the composite plate 6 is schematically consisting of the PVDF plate 2 and the polyester fleece 3, which are homogeneously connected to one another, shown. This composite plate 6 can for example Serve as a semi-finished product for container construction and can, for example, with fiberglass-reinforced unsaturated Polyester resins are reinforced on the polyester fleece side 3 building up.
Der homogene Verbund, der erzielt wird, weist eine höhere interlaminare Zugfestigkeit, gemessen nach DIN 53397, auf, als ein Verbundkörper aus PVDF mit einem Glasgewebe. Nachfolgend wird dies an einem Beispiel belegt.The homogeneous bond that is achieved shows a higher interlaminar tensile strength, as measured DIN 53397, as a composite body made of PVDF with a glass fabric. This is shown below on a Example occupied.
Als Probekörper 1 wurden zwei erfindungsgemäß hergestellte PVDF-Verbundplatten mit einem PcIyectervlies
eines Flächengewichtes von 150 g/m- von 30 mm Durchmesser mit ihrer PVDF-Seite auf einen
PVDF-Prüfkörper aufgeschweißt und dann an ihren Polyestervliesseiten mit einem Haftvermittler verklebt.
Der Probekörper 2 wurde unter Einsatz von zwei PVDF-Platten mit einem Durchmesser von
ebenfalls 30 mm kaschiert mit einem Glasgewebe von 300 g/m2 analog hergestellt. Für die Probekörper 1
und 2 wurde als Haftvermittler ungesättigtes Polyesterharz verwendet. Der Harzansatz für den Haftvermittler
setzte sich zusammen aus:
100 Gew.-Teile ungesättigtes PolyesterharzAs test specimen 1, two PVDF composite panels produced according to the invention with a PcIyect nonwoven with a weight per unit area of 150 g / m2 and 30 mm in diameter were welded with their PVDF side to a PVDF test specimen and then bonded to their polyester nonwoven sides with an adhesion promoter. The test specimen 2 was produced analogously using two PVDF plates with a diameter of 30 mm, also laminated with a glass fabric of 300 g / m 2. For specimens 1 and 2, unsaturated polyester resin was used as an adhesion promoter. The resin formulation for the adhesion promoter was made up of:
100 parts by weight of unsaturated polyester resin
2 Gew.-Teile Benzoylperoxidpulver2 parts by weight of benzoyl peroxide powder
1 Gew.-Teil Aminbeschleuniger 10%ig
(Dimethylanilin-Lösung)1 part by weight amine accelerator 10%
(Dimethylaniline solution)
Der Anpreßdruck beim Verkleben der Probekörper betrug etwa 0,01 N/mm2. Der sich anschließende Zugversuch nach DIN 53 397 erfolgte mit einem Vorschub von 5,5 m/min.The contact pressure when gluing the test specimens was about 0.01 N / mm 2 . The subsequent tensile test according to DIN 53 397 was carried out with a feed rate of 5.5 m / min.
In der nachfolgenden Tabelle sind die erreichten Werte der Stirnabzugsfestigkeit (interlaminare Zugfestigkeit) in Abhängigkeit von der Prüftemperatur aufgetragen:The table below shows the values achieved for the forehead peel strength (interlaminar tensile strength) applied depending on the test temperature:
Aus den Versuchen ergibt sich, daß die Stirnabzugsfestigkeit der erfindungsgemäß hergestellten Verbundkörper nahezu doppelt so hoch liegt als bei dem nach dem Stand der Technik hergestellten Verbundkörper mit Glasgewebe. Die Bruchfläche der Probekörper liegt bei dem PVDF-Polyestervlies-Probekörper innerhalb des Polyestervlieses, bei dem PVDF-GIasgewebe-Körper in der Ebene Glasgewebe/PVDF. Darüber hinaus weist der erfindungsgemäß hergestellte Verbundkörper über die gesamte Verbundfläche eine gleichmäßige Stirnabszugsfestigkeit auf.The tests show that the forehead peel strength of those produced according to the invention Composite body is almost twice as high as in the case of the composite body produced according to the prior art with glass fabric. The fracture surface of the test specimen lies with the PVDF polyester fleece test specimen inside the polyester fleece, with the PVDF glass fabric body in the glass fabric / PVDF level. In addition, the composite body produced according to the invention has over the entire Bond surface has a uniform forehead pull-off strength.
