Description

Gebiet der Erfindung Field of the invention

Die vorliegende Erfindung betrifft ein schichtförmiges Element, ein Verfahren zu seiner Herstellung und seine Verwendung. The present invention relates to a layered element, a process for its preparation and its use.

Stand der Technik State of the art

Schiefer wird beispielsweise für Dächer und Fassaden eingesetzt. Schiefer ist die Bezeichnung für durch sehr deutliche flächenhafte und/oder lineare Parallel-Gefüge (Schieferung) mit besonders ausgeprägter, ebener Spaltbarkeit ausgezeichnete Gesteine ( Römpp Chemie Lexikon, Stichwort „Schiefer“, 10. Auflage 1998, Georg Thieme Verlag ). Slate is used, for example, for roofs and facades. Slate is the name given to very distinct planar and / or linear parallel structure (schist) with particularly pronounced, even cleavage excellent rocks ( Römpp Chemie Lexikon, keyword "slate", 10th edition 1998, Georg Thieme Verlag ).

Schiefer kann als Furnier eingesetzt werden. Hierdurch können schichtförmige Elemente geschaffen werden. Allerdings besteht die Schwierigkeit, den Schiefer mit einem Trägermaterial zu verkleben. Problematisch ist beispielsweise die unebene Oberfläche des Schiefers, die in der Ebene mehrere Millimeter variieren kann. Weiterhin ist es bisher nicht möglich, den Schiefer mit Polystyrol, insbesondere geschäumtem Polystyrol, zu verkleben. Geschäumtes Polystyrol wird auf Grund seiner hohen Druckfestigkeit und geringen Wasseraufnahme oftmals bei der Dämmung von Gebäuden eingesetzt. Zudem ist es durch seine relativ geringe Dichte recht leicht und weist eine geringe Wärmekapazität auf. Slate can be used as a veneer. As a result, layered elements can be created. However, there is the difficulty to glue the slate with a carrier material. The problem is, for example, the uneven surface of the slate, which can vary in the plane several millimeters. Furthermore, it has not been possible to bond the slate with polystyrene, in particular foamed polystyrene. Foamed polystyrene is often used in the insulation of buildings due to its high pressure resistance and low water absorption. In addition, it is quite easy due to its relatively low density and has a low heat capacity.

Aufgabe task

Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, die zuvor beschriebenen Nachteile des Standes der Technik zu beseitigen. Es sollten schichtförmige Elemente zur Verfügung gestellt werden, die Polystyrol als Träger umfassen, auf denen der Schiefer aufgebracht und verklebt werden kann. Die schichtförmigen Elemente sollten sich insbesondere in einem einfachen Verfahren herstellen lassen. The present invention therefore an object of the invention to eliminate the disadvantages of the prior art described above. Layered elements should be provided which comprise polystyrene as a support on which the shale can be applied and glued. The layered elements should in particular be produced in a simple process.

Lösung der Aufgabe Solution of the task

Überraschenderweise wurden schichtförmige Elemente gefunden, die die Nachteile des Standes der Technik nicht aufweisen. Es wurden schichtförmige Elemente gefunden, die mit Polystyrol verklebt werden können. Surprisingly, layered elements have been found which do not have the disadvantages of the prior art. Layered elements were found that can be glued with polystyrene.

Demgemäß wurden schichtförmige Elemente gefunden, die die folgenden aufeinanderfolgenden Schichten umfassen:

  • a. Schiefer,
  • b. Bitumen,
  • c. Klebstoff, und
  • d. Polystyrol.
Accordingly, layered elements comprising the following successive layers have been found:
  • a. Slate,
  • b. Bitumen,
  • c. Glue, and
  • d. Polystyrene.

Der Schiefer fungiert bei dem schichtförmigen Element als Furnier, also als Belag von Elementen, um edle Optiken zu erzeugen. Insofern bildet die Schieferschicht in der Regel die äußere Schicht des schichtförmigen Elements. The slate acts as a veneer in the layered element, that is as a covering of elements to produce noble looks. In this respect, the slate layer usually forms the outer layer of the layered element.

Das schichtförmige Element ist vorzugsweise ein Plattenelement, das in seiner gesamten Ausdehnung eben ist und quer zur Ebene belastet werden kann. The layered element is preferably a plate element, which is flat in its entire extent and can be loaded transversely to the plane.

Bitumen ist nach DIN 55946 Teil 1 die Bezeichnung für die bei der schonenden Aufbereitung von Erdölen gewonnenen, dunkelfarbigen, halbfesten bis springharten, schmelzbaren, hochmolekularen Kohlenwasserstoff-Gemische und die in Schwefelkohlenstoff löslichen Anteile der natürlichen Asphalte sowie Erdwachs und Montanwachs (siehe auch Römpp Chemie Lexikon, Stichwort „Bitumen“, 10. Auflage 1996, Georg Thieme Verlag ). Das Bitumen wird aufgebracht, um dem Schiefermaterial eine gewisse Bruchfestigkeit zu verleihen. Zudem kann auf dem Schiefermaterial ein Vlies in die Bitumenschicht eingearbeitet sein. Bitumen is after DIN 55946 Part 1 is the name for the in the careful processing of petroleum derived, dark-colored, semi-solid to spring hard, fusible, high molecular weight hydrocarbon mixtures and the carbon disulfide soluble portions of natural asphalts and earth wax and montan wax (see also Römpp Chemie Lexikon, keyword "bitumen", 10th edition 1996, Georg Thieme Verlag ). The bitumen is applied to give the shale material a certain breaking strength. In addition, a fleece can be incorporated in the bitumen layer on the slate material.

Der Schiefer ist vorzugsweise ein Naturschiefer. Bevorzugt wird der Schiefer aus Buntschiefer und Quarzitschiefer ausgewählt. Der Schiefer weist vorzugsweise eine Schichtdicke von 0,1 mm bis 10 mm, bevorzugt 0,5 bis 5 mm, auf. Ein besonders geeignetes Produkt wird unter Bezeichnung Veneer S angeboten. The slate is preferably a natural slate. The slate is preferably selected from colored slate and quartzite schist. The slate preferably has a layer thickness of 0.1 mm to 10 mm, preferably 0.5 to 5 mm. A particularly suitable product is offered under the name Veneer S.

Als Klebstoff eignen sich übliche Schmelzklebstoffe, wobei Polyurethan-haltige Klebstoffe bevorzugt sind. Besonders bevorzugte Klebstoffe enthalten Diphenylmethandiisocyanate. Geeignete Diphenylmethandiisocyanate sind Diphenylmethan-2,2‘-diisocyanat, Diphenylmethan-2,4‘-diisocyanat und Diphenylmethan-4,4‘-diisocyanat. Geeignete Schmelzklebstoffe werden beispielsweise unter den Namen RAPIDEX® NP 2075 LT von H.B. Fuller angeboten. Suitable adhesives are customary hotmelt adhesives, with polyurethane-containing adhesives being preferred. Particularly preferred adhesives include diphenylmethane diisocyanates. Suitable diphenylmethane diisocyanates are diphenylmethane-2,2'-diisocyanate, diphenylmethane-2,4'-diisocyanate and diphenylmethane-4,4'-diisocyanate. Suitable hot melt adhesives are available from HB Fuller 2075 LT example, under the name RAPIDEX ® NP.

In einer bevorzugten Ausführungsform ist das Polystyrol geschäumt. Je nach Herstellungsart wird zwischen expandiertem Polystyrol-Hartschaum (EPS) und extrudiertem Polystyrol-Hartschaum (XPS) unterschieden. Die Schichtdicke des Polystyrols beträgt üblicherweise 15 mm bis 160 mm. In a preferred embodiment, the polystyrene is foamed. Depending on the type of production, a distinction is made between expanded polystyrene rigid foam (EPS) and extruded polystyrene rigid foam (XPS). The layer thickness of the polystyrene is usually 15 mm to 160 mm.

In einer Ausführungsform kann auf dem Polystyrol d als weitere Schicht e ein Material aufgebracht ist, das ausgewählt ist aus glasfaserverstärktem Kunststoff, Glas, Zement und Mischungen daraus. In one embodiment, on the polystyrene d as a further layer e, a material is applied, which is selected from glass fiber reinforced plastic, glass, cement and mixtures thereof.

Ein weiterer Gegenstand der Erfindung stellt ein Verfahren zur Herstellung der schichtförmigen Elemente dar. Dieses kennzeichnet sich durch die nacheinander ablaufenden Schritte a bis d, ggf. a bis e. Another object of the invention is a method for producing the layered elements. This is characterized by the successive steps a to d, possibly a to e.

In Schritt a wird der Schiefer zunächst einseitig mit Bitumen beschichtet. Die Schichtdicke beträgt in der Regel 0,01 bis 0,1 mm. Der Bitumen kann durch übliche Verfahren wie Gießen, Tauchen, Sprühen, Spritzen, Auftragen mit Walzen und Rakeln sowie Streichen erfolgen. Der Auftrag des Bitumens sollte oberhalb seines Erweichungspunkts, üblicherweise im Bereich von 40 °C bis 80 °C, liegen. Schieferarten wir Veneer S sind besonders bevorzugt. Diese wird auf Grund ihrer schimmernden, mehrfarbigen und unebenen Oberfläche als besonders dekorativ angesehen. Auf Grund der unebenen Oberfläche, die oftmals um bis zu 5 bis 8 mm variieren kann, ist das erfindungsgemäße Verfahren für diese Schieferart besonders gut geeignet. In step a, the slate is first coated on one side with bitumen. The layer thickness is usually 0.01 to 0.1 mm. The bitumen may be made by conventional methods such as pouring, dipping, spraying, spraying, roller and knife application, and brushing. The application of the bitumen should be above its softening point, usually in the range of 40 ° C to 80 ° C. Slate species such as Veneer S are particularly preferred. This is considered to be particularly decorative due to its shimmering, multicolored and uneven surface. Due to the uneven surface, which can often vary by up to 5 to 8 mm, the inventive method is particularly well suited for this type of slate.

Im Anschluss wird im Schritt b der Klebstoff auf die Bitumenschicht aus Schritt a aufgebracht. Der Klebstoff kann wie der Bitumen nach den genannten üblichen Verfahren aufgebracht werden. Ein vollflächiger Auftrag des Klebstoffs auf die Bitumenschicht ist dabei bevorzugt. Subsequently, in step b, the adhesive is applied to the bitumen layer from step a. The adhesive can be applied as the bitumen according to the usual methods mentioned. A full-surface application of the adhesive to the bitumen layer is preferred.

Im folgenden Schritt c wird das Zwischenprodukt aus Schiefer, Bitumen und Kunststoff auf Temperatur von 150 °C bis 180 °C erwärmt. Die Temperatur sollte dabei oberhalb der Verarbeitungstemperatur des Klebstoffs liegen. Je nach Auftragsart, Auftragsstärke und Schieferart sollte die Temperatur zwischen 10 s und 120 auf den Klebstoff einwirken. Der Auftrag des Klebstoffs und die darauffolgende Temperierung können beispielsweise mittels einer Beleimungsmaschine erfolgen. Durch die Erwärmung wird der Klebstoff aktiviert. Zudem erfolgt eine Verflüssigung des Bitumens, so dass sich Klebstoff und Bitumen unter Erhalt einer Bitumen- Klebstoff-Schicht miteinander vermischen. In the following step c, the intermediate product of shale, bitumen and plastic is heated to a temperature of 150 ° C to 180 ° C. The temperature should be above the processing temperature of the adhesive. Depending on the type of application, application thickness and type of slate, the temperature should be between 10 s and 120 on the adhesive. The order of the adhesive and the subsequent temperature control can be done for example by means of a gluing machine. The heating activates the adhesive. In addition, the bitumen liquefies, so that the adhesive and bitumen mix together to form a bitumen adhesive layer.

Alternativ kann der Auftrag des Klebstoffs bei der genannten Temperatur erfolgen, so dass die Schritte b und c miteinander kombiniert werden können. Alternatively, the application of the adhesive may take place at the said temperature, so that the steps b and c can be combined with one another.

Im Anschluss erfolgt im Schritt d ein Temperieren auf eine Temperatur im Bereich von 30 °C bis 70 °C und Auflegen des Polystyrols auf die Bitumen-Klebstoff-Schicht. Diese Temperatur kann erreicht werden, in dem von der Temperatur des Schritts c auf die Verarbeitungstemperatur des Schritts d abgekühlt wird. Alternativ kann zunächst auf Raumtemperatur (15 °C bis 25 °C) abgekühlt und anschließend auf die erforderliche Temperatur des Schritts d erwärmt werden. Thereafter, in step d, a temperature control to a temperature in the range of 30 ° C to 70 ° C and placing the polystyrene on the bitumen adhesive layer. This temperature can be reached by cooling from the temperature of step c to the processing temperature of step d. Alternatively, it can be first cooled to room temperature (15 ° C to 25 ° C) and then heated to the required temperature of step d.

Die optionale Schicht e kann im Anschluss in einem Schritt e auf das Polystyrol aufgebracht werden. Dies kann mit Klebstoffen erfolgen, die für die Verklebung von Polystyrol mit glasfaserverstärktem Kunststoff, Glas oder Zement geeignet sind. Dem Fachmann sind derartige Verklebungen bekannt. The optional layer e can then be applied to the polystyrene in a step e. This can be done with adhesives that are suitable for the bonding of polystyrene with glass fiber reinforced plastic, glass or cement. The person skilled in such adhesions are known.

In Versuchen zeigte sich, dass der Auftrag des Klebstoffs auf das Polystyrol und ein anschließendes Aufbringen der bitumenbeschichtetem Schiefer sowie der erforderlichen Erwärmung ein Element erzeugt, das eine deutlich geringere Klebkraft aufweist. Weiterhin wurde ermittelt, dass andere Materialien wie Polyurethan statt des Polystyrols weniger geeignet sind. Experiments have shown that the application of the adhesive to the polystyrene and subsequent application of the bitumen-coated slate and the required heating produces an element which has a significantly lower bond strength. It has also been found that other materials, such as polyurethane, are less suitable than polystyrene.

Die erfindungsgemäßen Elemente können für Möbel, insbesondere Gartenmöbel, als Wand- und Deckenverkleidung im Innen- und Außenbereich, im Innenausbau, im Laden- und Messebau, als Dekorationsartikel wie Wandbilder verwendet werden. Die Elemente können auf bereits bestehende Fliesen, Putz, Beton, Holz Stuck etc. aufgebracht werden. The elements according to the invention can be used for furniture, in particular garden furniture, as wall and ceiling paneling in the interior and exterior, in interior design, in shop and exhibition, as decorative items such as murals. The elements can be applied to existing tiles, plaster, concrete, wood stucco etc.
