Abstract
Description
Lochmetallbleche aus verschiedenen Metallen sind aus vielen Bereichen, vorwiegend in der Filtertechnik und auch im dekorativen Bereich, bekannt. Sie haben in der Regel die Eigenschaft, aus relativ dickem Material und dadurch sehr schwer zu sein, damit die Festigkeit des normalen Materials erreicht wird. Der Einsatz in Verbindung mit einer Kunststoffummantelung ist über den dekorativen Bereich kaum hinausgekommen. Perforated metal sheets made of different metals are from many areas, mainly in the Filter technology and also known in the decorative field. They usually have the property Made of relatively thick material and therefore very heavy, so that the strength of the normal Material is achieved. Use in conjunction with a plastic jacket is about the decorative area barely got out.
Die Erfindung stellt sich deshalb die Aufgabe, eine einfache und kostengünstige Verfahrenstechnik zu finden, die eine schlüssige Verbindung der Lochmetallplatte mit einem thermoplastischen Kunststoff und einer statisch wirksamen Tragschicht als Stützkern auf einfache Weise ermöglicht. The object of the invention is therefore a simple and inexpensive process technology to find a coherent connection of the perforated metal plate with a thermoplastic Plastic and a statically effective base layer as a support core allows in a simple manner.
In der Patentanmeldung DE 10 22 150.3 wird eine thermoplastische Lochmetall-Leichtbauplatte beschrieben, die in der Regel eine thermoplastische Verbindungsschicht zum stabilisierenden und damit tragenden Stützkern erforderlich macht und aufgrund der verschiedenen thermischen Ausdehnung der Materialien in der Regel mindestens zwei oder auch mehr Arbeitsgänge in der Herstellung erforderlich macht. Patent application DE 10 22 150.3 describes a thermoplastic perforated metal lightweight board described, which are usually a thermoplastic compound layer for stabilizing and thus supporting core is required and due to the different thermal Expansion of the materials usually at least two or more operations in the Manufacturing requires.
In der nachstehend beschriebenen Erfindung wird in einem Fertigungsgang der Stützkern, der entweder aus bekannten thermoplastisch verformbaren Kunststoff-Waben-, -Röhren-, Hütchen-, Kasten-, Steg-, Wellsteg- oder ähnlichen Strukturplatten oder auch Kunststoffschaumplatten besteht, direkt ohne Zwischenschicht mit einem oder zwei Lochblechen heißverpreßt und unter Druck abgekühlt, so daß sich das Stützkernmaterial selbst zu den für die schlüssige Verbindung erforderlichen Formen des Lochbleches verformt. In the invention described below, the support core, the either from known thermoplastically deformable plastic honeycombs, tubes, cones, Box, web, corrugated web or similar structural panels or plastic foam panels exists, directly with one or two perforated sheets without an intermediate layer and under Pressure cooled, so that the support core material itself to that for the coherent connection necessary shapes of the perforated plate deformed.
Alle Eigenschaften, die von der später sichtbaren Deckschicht erwartet werden, wie z. B. Farbe, Witterungs-, Temperatur- und UV-Beständigkeit, Elastizität, Zug- und Biegeeigenschaften sowie thermoplastische Verformbarkeit unter Druck usw. bringt hier dann bereits der thermoplastische Stützkern mit, der auch die Festigkeiten und Biegeeigenschaften sowie insbesondere das Gesamtgewicht zu einem großen Teil positiv beeinflußt. All properties that are expected from the later visible top layer, such as B. color, Weather, temperature and UV resistance, elasticity, tensile and bending properties as well Thermoplastic deformability under pressure, etc., already brings the thermoplastic here Support core with, which also the strength and bending properties and in particular that Overall weight largely influenced positively.
Eine zusätzliche, besondere Eigenschaft des Lochmetallbleches, nämlich die vorhandene Versenkung oder Tütung der Löcher und damit der Möglichkeit, eine glatte Oberfläche der Deckschicht, die dann aus Metall und Kunststoff sichtbar wird, eröffnet bei Bedarf weitere Anwendungsfelder und stellt die gleichmäßige, einwandfreie schlüssige Verkrallung und Verbindung des Bleches zum Kunststoffmaterial in Form einer Vielzahl von Nietköpfen sicher. An additional, special property of the perforated metal sheet, namely the existing one Sinking or tapping the holes and thus the possibility of a smooth surface of the The top layer, which is then made of metal and plastic, opens up more if necessary Fields of application and provides the uniform, perfect coherent claw and Secure connection of the sheet to the plastic material in the form of a large number of rivet heads.
Durch die Höhe des Stützkerns vor der Verpressung kann jede endgültige Dicke der Hochleistungs-Lochmetall-Kunststoffplatte bestimmt werden. Ungenauigkeiten und Toleranzen der Stützkernplatten werden durch die Vorgabe der endgültigen Höhe genauso ausgeglichen wie leichte Ungenauigkeiten in der Planheit der Lochmetallbleche oder bei der Lochung entstandene Gräte. Due to the height of the support core before pressing, any final thickness of the High-performance perforated metal plastic plate can be determined. Inaccuracies and tolerances Support core plates are compensated by specifying the final height as well slight inaccuracies in the flatness of the perforated metal sheets or in the perforation Bone.
Des weiteren kann mit einer Erweiterung der Höhe des Stützkernmaterials die Dicke der verbindenden Thermoplastschicht und damit die Steifheit und Biegefestigkeit, also die Stabilität der fertigen Platte beieinflußt werden. Furthermore, with an increase in the height of the support core material, the thickness of the connecting thermoplastic layer and thus the stiffness and bending strength, ie the stability of the finished plate can be influenced.
Durch den festen Einschluß des Metalls in den chemisch resistenten Kunststoff im Lochbereich ist es sogar möglich, eine nachträgliche Veredelung des Metalls an den sichtbaren Oberflächen, wie z. B. eine Eloxierung bei Aluminium, durchzuführen, so daß auf einen Schutz dieser Flächen bei der Verpressung verzichtet werden kann. Due to the solid inclusion of the metal in the chemically resistant plastic in the hole area it is even possible to retrofit the metal to the visible surfaces, such as z. B. anodizing aluminum, so that to protect these surfaces pressing can be dispensed with.
Durch die Wahl der Lochformen und -größen sowie deren lineare oder versetzte Anordnung im Lochmetallblech und auch durch die Tiefe der Lochversenkung kann sowohl den Lochgrößen der Waben, Kasten oder Röhren, als auch dem Abstand der Stege oder Hütchen usw. im Stützkern voll Rechnung getragen und immer eine schlüssige, langfristig stabile Verbindung erzielt werden. Auch insbesondere das Gewicht der fertigen Platte läßt sich dadurch auf den Anwendungszweck abstimmen, so daß in der Leichtigkeit der Platten optimale Ergebnisse erzielt werden. By choosing the hole shapes and sizes as well as their linear or offset arrangement in the Perforated metal sheet and also by the depth of the hole countersink can both the hole sizes of the Honeycombs, boxes or tubes, as well as the distance between the webs or cones etc. in the support core fully taken into account and always a coherent, long-term stable connection can be achieved. In particular, the weight of the finished plate can be based on the application vote so that optimal results are achieved in the lightness of the plates.
Weiter kann bereits bei der Verpressung jede erforderliche Art der Verformung oder Anformung in der Dicke und Form, im Randbereich durch Auf- und Abkantungen sowie erforderliche Ausstanzungen mit entsprechenden Werkzeugen hergestellt werden. Oberflächenstrukturen beim Kunststoff können durch die entsprechende Gestaltung der Trennfolien mit jeder Art erhabener oder vertiefter Strukturen, auch z. B. für die Rutschfestigkeit oder mit Schriftzügen und Bildern, erzeugt werden. Furthermore, any required type of deformation or molding in can already during the pressing the thickness and shape, in the edge area due to edging and folding as well as required Die cuts can be made with appropriate tools. Surface structures in Plastic can be raised with any type of raised by the appropriate design of the release films or deepened structures, also e.g. B. for slip resistance or with lettering and pictures, be generated.
Wichtig ist noch, daß die Hochleistungs-Lochmetall-Kunststoffplatte sowohl in einer stationären Heiß-/Kühlpresse als auch in einer Doppelbandpresse mit kontinuierlicher Zufuhr des Materials hergestellt werden kann. It is also important that the high-performance perforated metal plastic plate in both a stationary Hot / cooling press as well as in a double belt press with continuous feeding of the material can be manufactured.
Eine Gasdurchlässigkeit oder Gasdichtheit des Stützkerns ermöglicht auch gleiche Eigenschaften der Hochleistungs-Lochmetall-Kunststoffplatten und erweitert deren Einsatzmöglichkeiten. A gas permeability or gas tightness of the support core also enables the same properties the high-performance perforated metal plastic plates and expands their possible uses.
Nicht nur besonders Gerüst-, Boden- und Schalplatten und eine Vielzahl von anderen, auf Steifheit und Biegefestigkeit beanspruchte Platten und tragende oder nichttragende Profile können in der Regel in einem Preßvorgang aus Stützkern und Lochmetallplatte(n) mit der Anwendung dieses Verfahrens kostengünstig und in viel leichter zu handhabender Gewichtsklasse hergestellt werden. Durch den Verzicht auf den als Stand der Technik bekannten Einsatz von Glas- und anderem Fasermaterial ist es auch möglich, die Platten voll zu recyclen. Not only especially scaffold, floor and formwork panels and a variety of others, on stiffness and flexural strength stressed plates and load-bearing or non-load-bearing profiles can in the Usually in a pressing process from support core and perforated metal plate (s) with the application of this Process inexpensive and in a much easier to handle weight class. By dispensing with the use of glass and others known as prior art It is also possible to fully recycle the panels using fiber material.
