Abstract

A sandwich construction sheet, and particularly one for use in the building industry, consists of two different layers bonded together, one being a lightly expanded closed-cell PVC foam; the second layer is polystyrene foam. An example is a wall panel consisting of the PVC foam bonded to extruded polystyrene foam. The back of the polystyrene has a series of parallel grooves to maximise the surface area for applied adhesive. By this means the panel is securely and durably bonded to the wall which requires the thermal insulation. An alternative product has the polystyrene foam as core between two skins of the PVC foam. This has both better thermal insulation and also higher compression and bending strength. ADVANTAGE - The product has good thermal insulation, low weight, high stability, low production cost and ease of working.

Description

Die Erfindung bezieht sich auf eine Sandwichplatte, insbe­ sondere zur Verwendung im Baubereich, aus zwei miteinander verbundenen, unterschiedlichen Schichten, wobei eine der Schichten aus einem leicht geschäumten, geschlossenzelligen Polyvinylchlorid-Schaumstoff besteht.The invention relates to a sandwich panel, in particular especially for use in construction, from two together connected, different layers, one of the Layers of a slightly foamed, closed-cell Polyvinyl chloride foam is made.

Aus dem DE 76 24 223 U1 ist eine Isolier-Verbundplatte zum Trockenausbau von Wohnräumen bekannt, bei der auf einer Hartschaumplatte eine Karton-Hartfaser- oder Sperrholz-Plat­ te als Deckplatte aufkaschiert ist. Die freie Oberfläche der Deckplatte ist hierbei entweder mit einer Kunststoff-Folie, einer Korkschicht, einem Edelholzfurnier, einer Textil- oder Gewebetapete überzogen. Eine solche Isolier-Verbundplatte ist jedoch weder für den Außen- noch Naßbereich geeignet.From DE 76 24 223 U1 an insulating composite panel for Dry lining of living spaces known in the case of a Hard foam board is a cardboard hardboard or plywood board te is laminated as a cover plate. The free surface of the Cover plate is either with a plastic film, a layer of cork, a fine wood veneer, a textile or Fabric wallpaper covered. Such an insulating composite panel is not suitable for outdoor or wet areas.

Weiterhin befindet sich bereits eine Hart-Schaumstoff-Platte aus leichtgeschäumtem, geschlossenzelligen Polyvinylchlorid- Schaumstoff auf dem Markt, die sich durch eine besonders feinzellige, homogene Struktur auszeichnet. Darüber hinaus ist diese Hart-Schaumstoff-Platte nur halb so schwer wie eine gleichgroße, übliche Polyvinylchlorid-Platte gleicher Dicke. Diese, in unterschiedlichen Farben herstellbare Plat­ te ist zähhart und nimmt kein Wasser auf, jedoch besitzt sie keine ausreichende Wärmedämmung und ist verhältnismäßig kostspielig. Die Anwendungsbereiche der Hart-Schaumstoff- Platte sind: Messestandbau und Ladenbau; Siebdruck, Schilder, Beschriftungstafeln; Fotokaschierungen; Display, Innenarchitektur, Schaufenstergestaltung, Fernseh- und Theaterdekoration; thermogeformte Teile für den Industrie- und Konsumgüterbereich; Belagsplatten für Arbeitstische, Regale, Schränke; elektrische Apparate- und Gehäusebau; Behälterbau und Behälterauskleidungen; Bäder für galvanische und fotographische Zwecke; Klimakanäle, Rein- und Naßräume; Modellbau, Führungsschablonen; Bastel- und Hobbymarkt (Sperrholzersatz).There is also a hard foam sheet made of lightly foamed, closed-cell polyvinyl chloride Foam on the market, which is characterized by a special characterized by fine-celled, homogeneous structure. Furthermore this hard foam board is only half as heavy as an equal-sized, common polyvinyl chloride plate the same Thickness. This plat, which can be made in different colors te is tough and does not absorb water, but it does insufficient insulation and is proportionate expensive. The application areas of hard foam Plate are: exhibition stand construction and shopfitting; Screen printing,  Signs, labeling boards; Photo lamination; Display, Interior design, window dressing, television and Theater decoration; thermoformed parts for industrial and consumer goods area; Covering plates for work tables, Shelves, cupboards; electrical apparatus and housing construction; Tank construction and lining; Galvanic baths and photographic purposes; Air conditioning ducts, clean and wet rooms; Model making, guide templates; Craft and hobby market (Plywood replacement).

Bekannt sind auch wärmedämmende Wand- und Deckenbekleidungen aus Polystyrol-Hartschaum in Platten- oder Rollenform. Sie werden in der Regel unter der eigentlichen Tapete angebracht und dienen der Wärmedämmung. Sie haben gleichzeitig den Vorteil, daß sie Unebenheiten in der Wand auch überbrücken können, und daß sie auch als Untertapete dienen können, wenn ein dunkler oder farbiger Untergrund gegenüber der Decktape­ te abgedeckt werden soll. Hartschaum-Wärmetapeten sind je­ doch insofern nachteilig, als sie sich leicht eindrücken lassen. Jede ungewollte Belastung des Polystyrol-Hartschaums kann daher zu einer Eindruckstelle führen, die sehr störend wirkt. Vor allem können solche Eindruckstellen nicht repa­ riert werden. Die Rückstellkräfte des Hartschaums reichen meistens nicht aus, um die Eindruckstelle wieder zu füllen, und die Decktapete ist dazu an der Eindruckstelle meistens auch noch eingerissen.Thermal insulation wall and ceiling coverings are also known Made of rigid polystyrene foam in sheet or roll form. they are usually placed under the actual wallpaper and serve as thermal insulation. You have that at the same time The advantage that they also bridge unevenness in the wall can, and that they can also serve as sub-wallpaper if a dark or colored background opposite the top tape te should be covered. Hard foam heat wallpapers are ever but disadvantageous in that they are easily indented to let. Any unwanted load on the polystyrene rigid foam can therefore lead to an impression point that is very annoying works. Above all, such imprints cannot be repeated be cured. The restoring forces of the rigid foam are sufficient mostly not enough to fill up the impression point again, and the cover wallpaper is usually at the point of impression also torn down.

Der Erfindung liegt die Aufgabe zugrunde, eine Sandwichplat­ te der eingangs genannten Art zu schaffen, die eine hohe Wärmedämmung, ein geringes Gewicht sowie eine hohe Stabi­ lität bei gleichzeitig gegebener preiswerter Herstellung und problemloser Verarbeitung aufweist.The invention has for its object a sandwich te of the type mentioned above, which create a high Thermal insulation, low weight and high stability lity with inexpensive manufacture and easy processing.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als zweite Schicht ein Polystyrol-Schaumstoff auf die Polyvinyl­ chlorid-Schaumstoffschicht kaschiert ist.This object is achieved in that as  second layer a polystyrene foam onto the polyvinyl chloride foam layer is laminated.

Durch diese Maßnahme ergibt sich eine Sandwichplatte, deren aus Polyvinylchlorid-Schaumstoff bestehende Vorderseite ab­ waschbar ist, in beliebigen Farben ausgeführt werden kann und dadurch optisch äußerst ansprechend wirkt, gegebenen­ falls tapezierbar oder mit Fliesen beklebbar oder lackierbar ist, und deren aus Polystyrol-Schaumstoff bestehende Rück­ seite mittels eines Klebers leicht an einer zu isolierenden Wand befestigt werden kann. Durch den Einsatz von Poystyrol- Schaumstoff wird eine beachtliche Kosten- und Gewichtsredu­ zierung erreicht, da Polystyrol-Schaumstoff im Vergleich zu Polyvinylchlorid-Schaumstoff preiswerter und leichter ist. Die somit erzielte Leichtigkeit der Sandwichplatte wirkt sich positiv auf den Transport, die Lagerung und die Verar­ beitung aus. Darüber hinaus gewährleistet der Polystyrol- Schaumstoff eine hohe Wärmedämmung. Schließlich ist durch die Wasserfestigkeit der Polyvinylchlorid-Schaumstoffschicht ein Einsatz der Sandwichplatte im Naßbereich oder im Außen­ bereich möglich. Es werden also neue Einsatzbereiche für Sandwichplatten erschlossen. Es versteht sich von selbst, daß die erfindungsgemäße Sandwichplatte in den verschie­ densten Breiten, Längen, also gegebenenfalls auch als fortlaufende Bahn, hergestellt werden kann.This measure results in a sandwich panel, the front made of polyvinyl chloride foam is washable, can be run in any color and thus looks visually extremely appealing if it can be papered or covered with tiles or painted is, and their back made of polystyrene foam side easily with an adhesive on an insulated Wall can be attached. By using poystyrene Foam is a considerable cost and weight reduction decoration achieved because polystyrene foam compared to Polyvinyl chloride foam is cheaper and lighter. The lightness of the sandwich panel thus achieved works has a positive effect on transport, storage and processing processing. In addition, the polystyrene Foam high thermal insulation. Finally is through the water resistance of the polyvinyl chloride foam layer use of the sandwich panel in wet areas or outdoors area possible. So there are new uses for Sandwich panels opened up. It goes without saying that the sandwich plate according to the invention in the various most widths, lengths, possibly also as continuous web, can be produced.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist die Polystyrol-Schaumstoffschicht beidseitig mit einer Polyvi­ nylchlorid-Schaumstoffschicht kaschiert. Dies ermöglicht es, die Sandwichplatte als preiswerte Zwischenwand mit großer Steifigkeit und hoher Wärmedämmung einzusetzen.According to an advantageous embodiment of the invention Polystyrene foam layer on both sides with a Polyvi Laminated nyl chloride foam layer. This enables the sandwich panel as an inexpensive partition with a large Rigidity and high thermal insulation.

Zweckmäßigerweise besteht die Polystyrol-Schaumstoffschicht aus extrudiertem Polystyrol-Hartschaum. Alternativ hierzu kann die Polystyrol-Schaumstoffschicht auch aus einfachem Blockpolystyrol hergestellt sein.The polystyrene foam layer expediently consists made of extruded polystyrene hard foam. Alternatively  the polystyrene foam layer can also be made of simple Block polystyrene.

Um eine dauerhafte Befestigung der Sandwichplatte an einer zu isolierenden Wand mittels eines Klebers zu erzielen, ist nach einer vorteilhaften Weiterbildung des Gegenstandes der Erfindung die freie Seite der Polystyrol -Schaumstoffschicht mit Vertiefungen und/oder Erhöhungen versehen. Hierdurch wird die Anriebfläche des Klebstoffes auf der Rückseite der Sandwichplatte wesentlich erhöht, d. h. die Verankerungsflä­ che des Klebstoffes mit der Sandwichplatte wird größer, wo­ durch eine äußerst feste und sonach bleibende Verbindung zwischen der Platte und der zu isolierenden Wand erzielt wird. Die auf der Rückseite der Platte angebrachten Vertie­ fungen und/oder Erhöhungen können die verschiedensten Ausgestaltungen aufweisen. Bevorzugt sind die Vertiefungen als durchgehende, parallel zueinander verlaufende Rillen ausgeführt.To permanently attach the sandwich panel to a wall to be insulated using an adhesive after an advantageous development of the subject of Invention the free side of the polystyrene foam layer provided with depressions and / or elevations. Hereby the drive surface of the adhesive on the back of the Sandwich plate significantly increased, d. H. the anchoring surface surface of the adhesive with the sandwich panel gets bigger where thanks to an extremely strong and permanent connection achieved between the plate and the wall to be insulated becomes. The vertie on the back of the plate Additions and / or increases can be the most varied Have configurations. The depressions are preferred as continuous, parallel grooves executed.

In weiterer Ausgestaltung der Erfindung ist die Polystyrol- Schaumstoffschicht dicker als die Polyvinylchlorid-Schaum­ stoffschicht ausgebildet. Hierdurch wird insbesondere eine hohe Wärmedämmung sowie preiswerte Herstellung erreicht.In a further embodiment of the invention, the polystyrene Foam layer thicker than the polyvinyl chloride foam fabric layer. This will in particular high thermal insulation and inexpensive production achieved.

Der der Erfindung zugrundeliegende Gedanke wird in der nachfolgenden Beschreibung anhand zweier Ausführungsbei­ spiele, die in der Zeichnung dargestellt sind, näher erläu­ tert. Es zeigt:The idea underlying the invention is in the the following description based on two examples games, which are shown in the drawing, explained in more detail tert. It shows:
