Abstract

Verfahren zur Herstellung eines evakuierten Dämmelements, bestehend aus einem Kern- bzw. Stützteil vorzugsweise aus offenzelligem Hartschaumstoff und einer dieses Teil luftdicht umschließenden Folie, deren Inneres evakuiert wird, dadurch gekennzeichnet, dass die Folie mit dem Kern- bzw. Stützteil mittels eines Klebers kraftschlüssig verbunden wird.A method for producing an evacuated Dämmelements, consisting of a core or support member preferably made of open-cell foam and a part of this airtight enclosing foil whose interior is evacuated, characterized in that the film with the core or support member by means of an adhesive positively connected becomes.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1.The The invention relates to a method according to the preamble of the claim 1.

Ein derartiges Herstellungsverfahren ist vielfach bekannt, beispielsweise aus WO 99/61503 A1 . Das Kern- bzw. Stützteil dieses bekannten Dämmelementes besteht hier aus pulverförmigem oder festem Stützmaterial und ist mit einer Vakuumfolie umhüllt. Geht das Vakuum bzw. der Unterdruck durch Verletzung der Folie oder aus sonstigen Gründen verloren, so liegt oder flattert die Folie lose auf dem Stützteil. Abgesehen von einer drastischen Verschlechterung der Dämmleistung durch den Verlust des Vakuums verliert dabei das Dämmelement auch meist die stützende oder konstruktive Eigenschaft. Auch beim Einbringen des Dämmelements in einen weiteren Sandwichaufbau würde beim Verlust des Vakuums der innige Verbund des Sandwichaufbaus verloren gehen und die Gefahr bestehen, dass das Dämmelement ausbaucht oder auseinander fällt. Die durch bekannte Verfahren hergestellten evakuierten Dämmelemente sind daher nur sehr begrenzt anwendbar, nämlich als reines Einlegeteil in ein Gehäuse, wie beispielsweise das Gehäuse eines Kühlschranks.Such a manufacturing method is widely known, for example WO 99/61503 A1 , The core or support part of this known insulating element consists here of powdered or solid support material and is coated with a vacuum film. If the vacuum or the negative pressure is lost due to damage to the film or for other reasons, the film lies or flutters loosely on the support part. Apart from a drastic deterioration of the insulation performance due to the loss of the vacuum, the insulating element also loses most of the supporting or constructive property. Even when introducing the Dämmelements in a further sandwich structure would be lost to the loss of the vacuum, the intimate bond of the sandwich structure and there is a risk that the insulating element bulges or falls apart. The evacuated insulation elements produced by known methods are therefore very limited applicability, namely as a pure insert in a housing, such as the housing of a refrigerator.

Als weiterer Stand der Technik wird die DE 198 33 566 A1 genannt.As a further prior art, the DE 198 33 566 A1 called.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Herstellungsverfahren für ein derartiges evakuiertes Dämmelement zu schaffen, das auch bei Verlust des Vakuums seine Stützeigenschaft weitgehend aufrechterhält und daher sehr vielseitig als konstruktives Element einsetzbar ist.Of the The invention is therefore based on the object, a manufacturing method for a such evacuated insulation element to create, even with loss of the vacuum its support property largely maintained and therefore very versatile as a constructive element can be used.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Durch die kraftschlüssige Verklebung des vorzugsweise aus Hartschaum bestehenden Stützteiles mit der dieses umschließenden Folie wird sichergestellt, dass die konstruktive Festigkeit des Dämmelements auch bei Verlust des Vakuums weitgehend erhalten bleibt.These The object is achieved by the Characteristics of claim 1 solved. By the non-positive Bonding of the preferably made of rigid foam support member with this surrounding Foil ensures that the structural strength of the insulating element is largely retained even if the vacuum is lost.

Die Unteransprüche sind auf vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens gerichtet. Die Ansprüche 2 und 3 betreffen die Anwendung und Form des Klebers, während die Ansprüche 4 und 5 auf die Ausbildung des Dämmelements als plattenförmiges Element, als sogenanntes Paneel, und insbesondere dessen Verklebung mit weiteren Materialien zu einem Sandwich-Aufbau, gerichtet sind. Die Ansprüche 6 bis 8 befassen sich mit der Wahl bevorzugter Materialien und die Größe des anzuwendenden Unterdrucks bei der Vakuumausbildung.The under claims are on advantageous embodiments of the method according to the invention directed. The requirements 2 and 3 relate to the application and form of the adhesive, while the claims 4 and 5 on the formation of the Dämmelements as a plate-shaped Element, as a so-called panel, and in particular its bonding with other materials to a sandwich structure, are addressed. The claims 6 to 8 are concerned with the choice of preferred materials and the size of the applicable Vacuum at the vacuum training.
