Abstract

Description

Es ist bekannt, wärmeisolierende Körper (Vakuumpaneele) aus einem porösen Material und einer allseitig umhüllenden gasdichten Folie herzustellen, wobei der durch das poröse Material gebildete "Hohlraum" evakuiert wird. Das poröse Material kann entweder aus einem porigen Schüttgut oder aber aus einem harten Schaumstoff bestehen. Die Folie besteht üblicherweise aus Kombinationen von mehreren Schichten, wobei durch die verschiedenen Schichten unterschiedliche Aufgaben, wie Diffusionssperre gegenüber verschiedenen Gasen und mechanische Verfestigung, gelöst werden.It is known to heat-insulating body (vacuum panels) from a porous To produce material and a gas-tight film enveloping on all sides, the "cavity" formed by the porous material is evacuated. The porous material can either be from a porous bulk material or from a hard foam consist. The film usually consists of combinations of several Layers, whereby different tasks, such as Diffusion barrier against various gases and mechanical solidification, be solved.

Die meisten marktgängigen Vakuumpaneele haben einen Kern aus poröser Schüttung, üblicherweise auf Silikat-Basis.Most vacuum panels on the market have a core made of porous fill, usually based on silicate.

In der EP-B 188 806 werden harte Schaumstoffe auf Polyurethan-Basis als Füllmate­ rial für Vakuumpaneele beschrieben. Das Problem bei diesem Verfahren ist, durch genaue Rezepturwahl und durch Einhalten bestimmter Verfahrensparameter die erforderliche Offenzelligkeit zu erreichen. Von Natur aus sind PUR-Hartschaumstoffe vorwiegend geschlossenzellig. Ein weiteres Problem bei der Verwendung von PUR- Hartschaumstoffen als Trägermaterial für Vakuumpaneele stellt das Ausgasen flüch­ tiger Bestandteile, wie Amine, Treibmittel, evtl. auch Monomere, dar. Ein Vorteil von harten PUR-Schaumstoffen gegenüber porösen Schüttungen ist andererseits ihre genaue Dimensionierung als fertiges Vakuumpaneel, sowie ihre genaue Maßhaltig­ keit.In EP-B 188 806, rigid foams based on polyurethane are used as filling materials described for vacuum panels. The problem with this procedure is through exact recipe selection and by observing certain process parameters to achieve the required open cell. Rigid PUR foams are by nature predominantly closed cell. Another problem when using PUR Rigid foams as a carrier material for vacuum panels make outgassing bad components such as amines, blowing agents, possibly also monomers. An advantage on the other hand, hard PUR foams versus porous fillings are theirs  exact dimensioning as a finished vacuum panel, as well as its exact dimensional accuracy speed.

Überraschenderweise wurde nun gefunden, daß man ein ausgezeichnetes Trägermaterial für Vakuumpaneele auf wirtschaftliche Weise herstellen kann, indem man einen offenzelligen Kunststoffschaumstoff mit Polyisocyanaten härtet. Hierbei bedient man sich vorzugsweise der in der DE-AS 19 11 645 beschriebenen Verfah­ rensweise.Surprisingly, it has now been found that an excellent Can produce carrier material for vacuum panels in an economical manner by one cures an open-cell plastic foam with polyisocyanates. Here one preferably uses the procedure described in DE-AS 19 11 645 reindeer.

Erfindungsgemäß dient der offenzellige Kunststoff-Schaumstoff nur als Matrize; er benötigt keine Festigkeit. Die Festigkeit wird durch Tränken und anschließendes Aushärten mit dem erfindungsgemäß zu verwendenden Polyisocyanat erhalten.According to the invention, the open-cell plastic foam serves only as a matrix; he does not need firmness. The firmness is achieved by soaking and then Curing obtained with the polyisocyanate to be used according to the invention.

Gegenstand der Erfindung ist somit ein wärmeisolierender Körper, bestehend ausThe invention thus relates to a heat-insulating body consisting of

  • a) einem offenzelligen harten Kunststoff-Schaumstoff, der durch Tränken eines offenzelligen Kunststoff-Schaumstoffs mit Polyisocyanaten und anschließende Härtung erhalten wurde unda) an open-celled hard plastic foam, which is soaked by a open-cell plastic foam with polyisocyanates and subsequent Curing has been obtained and
  • b) einer den starren Kunststoff-Schaumstoff umhüllenden Folie, wobei die den Schaumstoff enthaltende Folie evakuiert und dann hermetisch versie­ gelt worden ist.b) a film enveloping the rigid plastic foam, the film containing the foam being evacuated and then sealed hermetically has been applied.

Erfindungsgemäß bevorzugt ist, daßIt is preferred according to the invention that

  • - der Kunststoff-Schaumstoff ein Polyurethanschaumstoff ist, - the plastic foam is a polyurethane foam,

  • - der Kunststoff-Schaumstoff eine Zellgröße von 0,01 mm bis 1 mm hat,- the plastic foam has a cell size of 0.01 mm to 1 mm,
  • - der mit dem Polyisocyanat getränkte Kunststoff-Schaumstoff vor der Umhül­ lung mit der Folie durch Tempern bei Temperaturen von 50 bis 250°C, vorzugsweise 120 bis 200°C, gegebenenfalls bei niedrigem Druck, von flüch­ tigen Bestandteilen befreit worden ist und- The plastic foam soaked with the polyisocyanate before the envelope treatment with the film by annealing at temperatures from 50 to 250 ° C, preferably 120 to 200 ° C, optionally at low pressure, of flüch components have been exempted and
  • - als umhüllende Folie eine mehrschichtige Folie, vorzugsweise eine Poly­ ethylen/Aluminiumfolie oder Polyethylen/Polyvinylalkoholfolie, verwendet wird.- As a wrapping film, a multilayer film, preferably a poly ethylene / aluminum foil or polyethylene / polyvinyl alcohol foil used becomes.

Für das erfindungsgemäß hergestellte Vakuumpaneel kommen alle bekannten Folien, z. B. Kombinationsfolien, wie sie auch bei der Herstellung von handelsüblichen Vakuumpaneelen verwendet werden, in Betracht. Beispielhaft seien genannt: Kom­ bination von Polyethylenfolie mit Polyvinylalkoholfolie oder Polyethylenfolie mit Aluminiumfolie.All known films come for the vacuum panel produced according to the invention, e.g. B. combination films, such as those used in the manufacture of commercially available Vacuum panels are used. Examples include: Com combination of polyethylene film with polyvinyl alcohol film or polyethylene film with Aluminum foil.

Als erfindungsgemaß zu verwendende Schaumstoffe (Matrix) kommen alle Kunst­ stoffschäume in Betracht. Da die notwendige Festigkeit durch nachträgliches Tränken und Polymerisieren der erfindungsgemäß zu verwendenden Isocyanate erfolgt, wird an die mechanische Festigkeit des Matrixschaumstoffes keine Anforderungen gestellt. Es ist jedoch von Bedeutung für die Wärmedämmeigenschaften der Vakuumpaneele, daß die verwendeten Schaumstoffe eine feine Zellstruktur besitzen. Erfindungsgemaß bevorzugt sind daher Schaumstoffe mit einer Zellgröße von <0,1 mm.All art come as foams (matrix) to be used according to the invention fabric foams into consideration. Because the necessary strength through subsequent soaking and polymerizing the isocyanates to be used according to the invention no demands were made on the mechanical strength of the matrix foam. However, it is important for the thermal insulation properties of the vacuum panels,  that the foams used have a fine cell structure. According to the invention foams with a cell size of <0.1 mm are therefore preferred.

Als Polyisocyanate kommen z. B. die in der DE-AS 19 11 645 genannten Polyiso­ cyanate in Frage.As polyisocyanates such. B. the Polyiso mentioned in DE-AS 19 11 645 cyanate in question.

Beim Tränken und Härten des Matrizenschaumstoffes mit den Polyisocyanaten folgt man gleichfalls vorzugsweise der Lehre der DE-AS 19 11 645.When soaking and hardening the matrix foam with the polyisocyanates follows also preferably the teaching of DE-AS 19 11 645.

Ein weiterer Vorteil der erfindungsgemäßen Vakuumpaneele besteht darin, daß der Schaumstoff vor oder nach dem Tränken und Härten vorkonfektioniert werden kann oder gegebenenfalls neben Vakuumpaneelen auch Vakuumformkörper hergestellt werden können.Another advantage of the vacuum panels according to the invention is that the Foam can be pre-assembled before or after soaking and curing or optionally also vacuum molded articles are produced in addition to vacuum panels can be.
