Le A 31 788 / Pt/bv/S-P Le A 31 788 / Pt/bv/SP
Vakuumisolierpaneele werden üblicherweise zur thermischen Isolierung eingesetzt. Bekannte Vakuumisolierpaneele bestehen aus einer vorkomprimierten porösen Schüttung, einer porösen Preßplatte oder einem offenzelligen harten Schaumstoff als Substrat, das von einer gasdichten Folie umhüllt wird, wobei die Folie nach dem Evakuieren verschweißt oder verklebt wird.Vacuum insulation panels are usually used for thermal insulation. Known vacuum insulation panels consist of a pre-compressed porous fill, a porous pressed plate or an open-cell hard foam as a substrate, which is covered by a gas-tight film, whereby the film is welded or glued after evacuation.
Solche Vakuumisolierpaneele werden auch bereits bei der Herstellung von Kühlräumen, z.B. Kühlschränken oder Kühlcontainern eingesetzt, indem diese zwischen Außen- und Innengehäuse eingelegt werden und der verbleibende Zwischenraum zwischen Außen- und Innengehäuse ausgeschäumt wird.Such vacuum insulation panels are already being used in the manufacture of cold rooms, e.g. refrigerators or refrigerated containers, by inserting them between the outer and inner casings and filling the remaining space between the outer and inner casings with foam.
Als Füllmaterial dienen beispielsweise gefällte und getrocknete Kieselsäuren, Silicagele, Flugasche, offenzellige Schäume auf organischer Basis wie offenzellige Polyurethan-Hartschäume oder gebundenes Polyurethan-Hartschaummehl, wie sie z.B. in der DE 4 439 331 und DE 4 439 328 beschrieben werden.Examples of filler materials used include precipitated and dried silica, silica gels, fly ash, open-cell foams on an organic basis such as open-cell polyurethane rigid foams or bound polyurethane rigid foam powder, as described, for example, in DE 4 439 331 and DE 4 439 328.
Für die umhüllenden Folien wird in der Regel ein asymmetrischer Aufbau gewählt, wobei eine Seite aus diffusionsdichter Aluminiumverbundfolie besteht, die andere Seite ein Mehrschichtverbund aus Kunststoffolie ist.An asymmetrical structure is usually chosen for the enveloping films, with one side consisting of diffusion-tight aluminum composite film and the other side being a multi-layer composite made of plastic film.
Die Verwendung metallhaltiger Deckschichten auf beiden Seiten unterblieb bisher, um den Wärmefluß über die Siegelnaht zu vermeiden.The use of metal-containing cover layers on both sides has so far been omitted in order to avoid heat flow via the sealing seam.
Erfindungsgemäß werden nun Vakuumisolierpaneelen vorgeschlagen, bei denen die Umhüllung beidseitig aus einer gasdichten metallhaltigen Deckschicht besteht. Überraschenderweise ist bei den erfindungsgemäßen Vakuumisolierpanellen der Beitrag der Wärmeleitung über die Siegelnaht zu vernachlässigen.According to the invention, vacuum insulation panels are now proposed in which the casing consists of a gas-tight metal-containing cover layer on both sides. Surprisingly, in the vacuum insulation panels according to the invention, the contribution of heat conduction via the sealing seam is negligible.
Gegenstand der vorliegenden Erfindung ist daher ein Vakuumisolierpaneel, bestehend aus beidseitig von einer metallhaltigen Deckschicht umhüllten Substrat.The subject of the present invention is therefore a vacuum insulation panel consisting of a substrate covered on both sides by a metal-containing covering layer.
Als Substrat ist eine gegebenenfalls vorverpreßte Schüttung aus gefällter Kieselsäure, Silicagel und/oder Polyurethanhartschaumpulver geeignet, wobei die Verpressung in Gegenwart von geeigneten Klebmitteln zur Gewährleistung einerA pre-pressed bed of precipitated silica, silica gel and/or polyurethane foam powder is suitable as a substrate, whereby the pressing is carried out in the presence of suitable adhesives to ensure

Eigenstabilität erfolgt sein kann. Ferner geeignet sind offenporige Polyurethan-Hartschaumplatten als Substrat.Inherent stability can be achieved. Open-pored polyurethane rigid foam boards are also suitable as a substrate.
Die erfindungsgemäßen Vakummisolierpanellen werden hergestellt, indem das Substrat mit der gasdichten metallhaltigen Deckschicht beidseitig umhüllt wird, evakuiert und dann hermetisch versiegelt wird.The vacuum insulation panels according to the invention are produced by covering the substrate on both sides with the gas-tight metal-containing cover layer, evacuating it and then hermetically sealing it.
Bevorzugt werden als Substrat Platten aus offenporigem Polyurethan oder Platten aus gebundenen Polyurethan-Hartschaummehl eingesetzt.The preferred substrate is panels made of open-pored polyurethane or panels made of bound polyurethane rigid foam powder.
Bevorzugt besitzen die erfindungsgemäßen Vakuumisolierpaneele eine Kantenlänge von mindestens 45 cm, bevorzugt 50 cm &khgr; 50 cm, insbesondere 100 cm &khgr; 100 cm. Die Dicke der erfindungsgemäßen Platten liegt üblicherweise im Bereich von 0,5 bis 5 cm.The vacuum insulation panels according to the invention preferably have an edge length of at least 45 cm, preferably 50 cm x 50 cm, in particular 100 cm x 100 cm. The thickness of the panels according to the invention is usually in the range of 0.5 to 5 cm.
Bevorzugt werden als metallhaltige Deckschichten Stahlblechplatten, besonders bevorzugt Edelstahlblechplatten eingesetzt.Steel sheet plates, particularly stainless steel sheet plates, are preferably used as metal-containing covering layers.
Messungen haben gezeigt, daß überraschenderweise die Wärmeleitfähigkeit der damit umhüllten Vakuumisolierpaneele nicht beeinflußt wird.Measurements have shown that, surprisingly, the thermal conductivity of the vacuum insulation panels covered with it is not affected.
Derartige Stahlblech- oder Edelstahlblechplatten sind bereits bekannt und kommerziell erhältlich.Such sheet steel or stainless steel plates are already known and commercially available.
Die erfindungsgemäßen Vakuumisolierpaneele werden zur Dämmung der Wandungen von Kühlräumen, Kühlcontainern, Kühlschränken und Kühltruhen eingesetzt.The vacuum insulation panels according to the invention are used to insulate the walls of cold rooms, refrigerated containers, refrigerators and freezers.
Die nachfolgenden Beispiele sollen die Erfindung näher erläutern, ohne sie jedoch in ihrem Umfang zu begrenzen.The following examples are intended to explain the invention in more detail without, however, limiting its scope.

58Og eines PUR-Hartschaummehles aus einer Kühlgeräterecyclinganlage werden mit 20 g Wasser und 58 g eines Polyisocyanatgemisches von Diphenylmethandiisocyanaten und Polyphenylpolymethylen-polyisocyanaten (Desmodur® VP PU 1520 A20; Bayer AG) mit einem Lödige-Pflugschar-Mischer mit 2-Stoffdüsen gleichmäßig vermischt. Aus dieser Mischung wird in einem Form-Rahmen ein Formling gebildet, gleichmäßig verdichtet und anschließend in einer Laborpresse unter einem Druck von 5 bar und einer Temperatur von 1200C 8 Minuten unter Verwendung eines Zeit-Meßprogrammes auf 20 mm verpreßt.580g of a PUR rigid foam powder from a refrigerator recycling plant are evenly mixed with 20g of water and 58g of a polyisocyanate mixture of diphenylmethane diisocyanates and polyphenylpolymethylene polyisocyanates (Desmodur® VP PU 1520 A20; Bayer AG) using a Lödige ploughshare mixer with 2-material nozzles. A molding is formed from this mixture in a mold frame, evenly compacted and then pressed to 20mm in a laboratory press under a pressure of 5 bar and a temperature of 120 ° C for 8 minutes using a time measuring program.
Man erhält hieraus eine poröse 20 mm-Platte mit einer Rohdichte von 200 kg/m3. Die Platte wird ca. 2 h auf 1200C erwärmt, um sie von allen flüchtigen Bestandteilen zu befreien.This produces a porous 20 mm plate with a density of 200 kg/m 3 . The plate is heated to 120 0 C for approx. 2 hours to remove all volatile components.
Die Platte wird mit je einer Stahlblechplatte auf beiden Seiten umhüllt, hermetisch versiegelt und evakuiert.The plate is covered with a sheet steel plate on both sides, hermetically sealed and evacuated.
