Stand der TechnikState of the art
I O DE-19815202-A1 beschreibt ein Isolationselement, welches insbesondere als Wärmeisolationsplatte für Aussenfassaden von Häusern vorgesehen ist. Dieses Isolationselement umfasst einen wärmedämmenden Innenkörper sowie eine diesen Innenkörper umschliessende und damit verbundene Ummantelung aus Polystyrol-Hartschaum. Der Innenkörper kann aus Phenolhartschaum, Polyurethanhartschaum oderI O DE-19815202-A1 describes an insulation element which is provided in particular as a heat insulation plate for exterior facades of houses. This insulation element comprises a heat-insulating inner body and a sheathing made of rigid polystyrene foam which surrounds and connects this inner body. The inner body can be made of rigid phenolic foam, rigid polyurethane foam or

Um einen sicheren Halt der Ummantelung auf dem Innenkörper zu gewährleisten, weist letzterer Profilierungen auf, welche eine formschlüssige Verbindung zwischen Ummantelung und Kern bewirken.15 mineral wool must be formed. In order to ensure a secure hold of the sheathing on the inner body, the latter has profilings, which bring about a positive connection between the sheathing and the core.
Ein Nachteil dieses sowie anderer bekannter Isolationselemente besteht darin, dass 20 sie für eine Vielzahl von Anwendungen eine zu hohe Wärmeleitfähigkeit aufweisen, so dass zur Erzielung einer vorgegebenen Wärmeisolation eine nicht tolerierbare Dicke des Isolationselementes erforderlich ist. So ist beispielsweise der Einsatz von Bodenheizungen in Altbauten oftmals nur unter Inkaufnahme erheblicher Wärmetransmissionsverluste gegen unbeheizte Zonen möglich, da wegen der beschränkten 25 Platzverhältnisse eine nur ungenügend dicke Wärmeisolationsschicht einbaubar ist.A disadvantage of this and other known insulation elements is that they have too high a thermal conductivity for a large number of applications, so that an intolerable thickness of the insulation element is required to achieve a predetermined heat insulation. For example, the use of underfloor heating in old buildings is often only possible when considerable heat transmission losses are incurred against unheated zones, since an insufficiently thick thermal insulation layer can be installed due to the limited space available.

Wei- 30 tere Aufgaben der Erfindung bestehen darin, eine Verwendung des erfindungsge- mässen Isolationselementes sowie ein Herstellungsverfahren für eine bevorzugte Ausgestaltung des Isolationselementes anzugeben. Gelöst werden diese Aufgaben durch das im Anspruch 1 definierte Isolationselement, durch die im Anspruch 8 angegebene Verwendung sowie durch das im Anspruch 9 definierte Verfahren.The object of the invention is to improve an insulation element of the type mentioned in the introduction so that it has a lower thermal conductivity. A further object of the invention is to specify a use of the insulation element according to the invention and a manufacturing method for a preferred embodiment of the insulation element.

Dadurch, dass beim Isolationselement nach Anspruch 1 der Innenkörper ein Dämmelement enthält, das aus einem unter Vakuum stehenden Kernteil gebildet ist, weist dieser Innenkörper eine gegenüber den in DE-19815202-A1 beschriebenen Innenkörpern wesentlich verbesserte Wärmeisolationsfähigkeit auf.Characterized in that in the insulation element according to claim 1, the inner body contains an insulating element which is formed from a core part which is under vacuum, this inner body has a substantially improved thermal insulation ability compared to the inner bodies described in DE-19815202-A1.

Durch die im Anspruch 8 definierte Verwendung des erfindungsgemässen Isolationselementes kann dieses anstelle eines äusserlich gleichen Isolationselementes nach dem Stand der Technik eingesetzt werden. Durch die Verwendung als Einbauele- ment lässt sich beispielsweise in einer vorbestehenden, aus einem oder mehreren bekannten Isolationselementen gebildeten wärmeisolierenden Anordnung ein ver- bessertes Wärmeisolationsverhalten unter Beibehaltung der vorgegebenen Abmessungen erreichen.Due to the use of the insulation element according to the invention as defined in claim 8, this can be used instead of an externally identical insulation element according to the prior art. By using it as a built-in element, for example, in a pre-existing heat-insulating arrangement formed from one or more known insulation elements, improved heat-insulation behavior can be achieved while maintaining the specified dimensions.
Dadurch, dass man beim Verfahren nach Anspruch 9 eine Aussenfläche des Dämmelementes mit einem Klebstoff belegt, danach das Dämmelement mit einem Kunst- stoffgranulat umgibt und dann letzteres zu einem geschäumten Kunststoff in einer Expansionszeitdauer expandiert, die kürzer ist als eine zur Aushärtung des Klebstoffes benötigte Aushärtungszeitdauer, lässt sich ein Isolationselement mit einer gut sitzenden, ablösefesten Ummantelung aus einem geschäumten Kunststoff herstellen.Characterized in that in the method according to claim 9 an outer surface of the insulating element is coated with an adhesive, then surrounds the insulating element with a plastic granulate and then the latter is expanded into a foamed plastic in an expansion time period which is shorter than a curing time period required for the curing of the adhesive , an insulation element with a well-fitting, detachable casing can be made from a foamed plastic.

Wege zur Ausführung der ErfindungWays of Carrying Out the Invention
Das in den Figuren 1 und 3 dargestellte Isolationselement weist einen wärmedämmenden Innenkörper 2 und eine diesen umschliessende und damit verbundene Ummantelung 4 auf. Dabei enthält der Innenkörper 2 ein an sich bekanntes Dämmele- ment 6, welches einen in einer hochgradig gasdichten Folie 8, beispielsweise einer Aluminium-Verbundfolie, eingeschweissten mikroporösen Kernteil 10 enthält, der unter Vakuum mit einem Druck von ungefähr 0, 1 mbar steht. Beispielsweise ist der Kernteil 10 aus einem offenzelligen, extrudierten Polystyrol oder aus pyrogener Kie- seisaure gebildet Derartige Dammelemente sind in verschiedenen Abmessungen erhältlich und weisen eine Wärmeleitfähigkeit von 0,004 bis 0,008 Wm 1K 1 auf, welche wesentlich geringer als diejenige von konventionellen Dammstoffen ist Beispielsweise betragt die Wärmeleitfähigkeit von expandiertem Polystyrol ungefähr 0,034 bis 0,040 Wm 1 K 1 und diejenige von Polyurethan ungefähr 0,024 bis 0,028 Wm 1K 1 The insulation element shown in FIGS. 1 and 3 has a heat-insulating inner body 2 and a sheathing 4 surrounding it and connected to it. The inner body 2 contains an insulation element 6 which is known per se and which contains a microporous core part 10 which is welded into a highly gas-tight film 8, for example an aluminum composite film, and which is under vacuum with a pressure of approximately 0.1 mbar. For example, the core part 10 is made from an open-cell, extruded polystyrene or from pyrogenic pine Seisaure formed Such dam elements are available in different dimensions and have a thermal conductivity of 0.004 to 0.008 Wm 1 K 1 , which is significantly lower than that of conventional dam materials.For example, the thermal conductivity of expanded polystyrene is approximately 0.034 to 0.040 Wm 1 K 1 and that of Polyurethane approximately 0.024 to 0.028 Wm 1 K 1
Die Ummantelung 4 dient dem Schutz der Folie 8 und soll insbesondere die Ausbildung von Undichtigkeiten infolge mechanischer Einwirkungen verhindern, da das Eindringen von Luft in das Dammelement 6 eine erhebliche Zunahme der Wärmeleitfähigkeit verursachen und dementsprechend einen weitgehenden Verlust der gewünschten Warmeisolationsfahigkeit bewirken wurdeThe sheathing 4 serves to protect the film 8 and, in particular, is intended to prevent the formation of leaks as a result of mechanical influences, since the penetration of air into the dam element 6 causes a considerable increase in the thermal conductivity and accordingly would result in a substantial loss of the desired heat insulation capability
Als Materialien für die Ummantelung 4 kommen beispielsweise Steinwolle, Glaswolle, Schaumglas, Kork, Leichtbauplatten aus Holzwolle, Holzfaserplatten sowie weitere warmedammende Materialien in Frage Besonders vorteilhaft sind geschäumte Kunststoffe wie expandiertes Polystyrol oder Polyurethan Alternativ kann aber auch ein durch Strangpressen hergestellter Kunststoff wie beispielsweise extrudiertes Polystyrol vorgesehen seinThe materials for the sheathing 4 include, for example, rock wool, glass wool, foam glass, cork, lightweight panels made of wood wool, wood fiber boards and other heat-insulating materials. Foamed plastics such as expanded polystyrene or polyurethane are particularly advantageous be provided
Um ein unerwünschtes Ablosen der Ummantelung vom lnnenkorper 2 zu vermeiden, ist die Ummantelung 4 vorteilhafterweise mit einer Aussenflache des Dammelementes 6 verklebtIn order to avoid undesired detachment of the sheathing from the inner body 2, the sheathing 4 is advantageously glued to an outer surface of the dam element 6
Wie aus der Figur 2 hervorgeht, weist die Folie 8 eine Mehrzahl von Schweissnahten 12 auf, die einen vakuumdichten Abschluss des Dammelementes 6 bilden Externe Folienabschnitte 14 bestehen aus Teilen der Folie 8, die sich bezüglich einer zugehörigen Schweissnaht 12 auf einer vom evakuierten Bereich des Dammelementes 6 abgewandten Seite befindenAs can be seen from FIG. 2, the film 8 has a plurality of weld seams 12, which form a vacuum-tight closure of the dam element 6. External film sections 14 consist of parts of the film 8 which, with respect to an associated weld seam 12, lie on one of the evacuated area of the dam element 6 are facing away
Bei der Herstellung des Isolationselementes ist es zweckmassig, vor Anbringen der Ummantelung 4 die externen Folienbereiche 14 in eine flach auf der Aussenflache aufliegende Stellung zu bringen, um einen guten Sitz der Ummantelung und die Bildung von wulstartigen Unebenheiten zu vermeiden.In the manufacture of the insulation element, it is expedient to place the external film areas 14 in a flat on the outer surface before attaching the casing 4 bring it into an overlying position to avoid a good fit of the casing and the formation of bulge-like bumps.
Je nach Art der Ummantelung bieten sich verschiedene Verfahren zur Herstellung des Isolationselementes an. Falls die Ummantelung 4 aus vorgefertigten Teilen besteht, werden letztere um das Dämmelement 6 herum angeordnet. Ein Zusammenhalt der einzelnen Teile wird beispielsweise dadurch bewerkstelligt, dass vor dem Zusammenbau des Isolationselementes die Ummantelungsteile und/oder das Dämmelement an geeigneten Kontakstellen mit einem Klebstoff belegt werden. Statt des Verklebens kann aber auch ein lokales Verschmelzen der Ummantelungsteile untereinander und/oder mit einer äusseren Schicht der Folie 8 herangezogen werden.Depending on the type of sheathing, there are various methods for producing the insulation element. If the casing 4 consists of prefabricated parts, the latter are arranged around the insulation element 6. Cohesion of the individual parts is achieved, for example, in that the casing parts and / or the insulation element are coated with an adhesive at suitable contact points before the insulation element is assembled. Instead of gluing, however, local fusing of the sheathing parts with one another and / or with an outer layer of the film 8 can also be used.
In einem bevorzugten Herstellungsverfahren wird die Ummantelung 4 um das Dämmelement 6 herum geschäumt, indem beispielsweise eine Schicht mit einer Dicke von 7 bis 10 mm aufgebaut wird. Besonders gute Ergebnisse werden dadurch erzielt, dass man das Dämmelement 6 zunächst mit einem Klebstoff belegt, danach das Dämmelement 6 mit einem Kunststoffgranulat umgibt und dann letzteres durch Wärmezufuhr, zum Beispiel mit Wasserdampf, zu einem geschäumten Kunststoff expandiert. Zu diesem Zweck ist ein Klebstoff zu wählen, der zur Aushärtung eine Aushär- tungszeitdauer t benötigt, die länger als eine zur Expansion des Kunststoffes benötigte Expansionszeitdauer t£ ist. Dadurch ist gewährleistet, dass während des Ein- schäumens die Kunststoffgranulatmasse gegenüber dem Dämmelement beweglich bleibt und sich so an die Form des Dämmelementes anpassen kann.In a preferred production process, the casing 4 is foamed around the insulating element 6, for example by building up a layer with a thickness of 7 to 10 mm. Particularly good results are achieved by first covering the insulating element 6 with an adhesive, then surrounding the insulating element 6 with a plastic granulate and then expanding the latter to a foamed plastic by supplying heat, for example with steam. For this purpose, an adhesive must be selected that requires a curing time t for curing that is longer than an expansion time t £ required for the expansion of the plastic. This ensures that the plastic granulate material remains movable relative to the insulation element during foaming and can thus adapt to the shape of the insulation element.
Expandiertes Polystyrol als Material der Ummantelung 4 weist gegenüber anderen Materialien wie beispielsweise Polyurethan den Vorteil auf, dass während des Ein- schäumens keine übermässige Wärmeentwicklung auftritt und damit eine Verformung oder ein Schmelzen des im Dämmelement 6 befindlichen Kernmaterials 10 oder seiner umhüllenden Folie 8 vermieden wird. Ein weiterer Vorteil von expandier- tem Polystyrol besteht darin, dass im Bauwesen herkömmliche Materialien für Verputz und Putzschichten auf Polystyrol abgestimmt sind. Somit kann ein Isolationselement mit Ummantelung aus expandiertem Polystyrol mit einer direkt aufgetragenen Putzschicht versehen werden. Damit ergibt sich insbesondere die Möglichkeit, das Isolationselement anstelle eines äusserlich gleichen, herkömmlichen Isolationselementes, beispielsweise anstelle eines homogen ausgebildeten Norm-Isolations- elementes zu verwenden.Expanded polystyrene as the material of the sheathing 4 has the advantage over other materials such as polyurethane, for example, that excessive foaming does not occur during foaming, and thus deformation or melting of the core material 10 located in the insulating element 6 or its enveloping film 8 is avoided. Another advantage of expanded polystyrene is that conventional materials for plastering and plaster layers in construction are matched to polystyrene. This means that an insulation element with a jacket made of expanded polystyrene can be provided with a directly applied layer of plaster. This results in particular in the possibility to use the insulation element instead of an externally identical, conventional insulation element, for example instead of a homogeneously formed standard insulation element.
