Description
Die Erfindung betrifft ein Vakuumisolationspaneel mit den Merkmalen des Oberbegriffs von Anspruch 1 sowie eine Umhüllungsfolie für Vakuumisolationspaneele mit den Merkmalen des Oberbegriffs von Anspruch 8.The invention relates to a vacuum insulation panel having the features of the preamble of
Vakuumisolationspaneele dienen der leistungsfähigen Isolierung von Kühl- und Gefriergeräten, der Isolierung von Transportbehältern für temperatursensitive Güter, zur nachträglichen Dämmung in der Gebäudesanierung etc.Vacuum insulation panels are used for efficient insulation of refrigerators and freezers, the insulation of transport containers for temperature-sensitive goods, for subsequent insulation in building renovation etc.
Ein Vakuumisolationspaneel hat grundsätzlich einen flächigen Kern aus offenporigem Material und eine den Kern an allen Seiten eng, vollständig und gasdicht umschließende Umhüllung. Dadurch ist es möglich, den Raum innerhalb der Umhüllung zu evakuieren und dadurch die Wärmeleitfähigkeit des Vakuumisolationspaneels auf sehr niedrige Werte zu bringen.A vacuum insulation panel basically has a flat core of open-pored material and a sheath surrounding the core on all sides in a tight, complete and gastight manner. This makes it possible to evacuate the space within the enclosure and thereby bring the thermal conductivity of the vacuum insulation panel to very low levels.
Bekannt ist ein Vakuumisolationspaneel (
Im Stand der Technik wird erläutert, dass sich für den Kern druckbelastbare Materialien in der Form von Pulverplatten, Pulverschüttungen, offenporigen Schäumen oder Glasfasermaterialien eignen. Insbesondere Dämmkerne aus Pulverplatten oder losem Pulver werden gewöhnlich noch zur Minderung der Staubbildung mit einem luftdurchlässigen Polyestervlies umhüllt, wie sich das beispielsweise aus der
Kernplatten aus mikroporösem Kieselsäurepulver weisen eine sehr feine Porenstruktur auf und lassen relativ hohe Gasdrücke zu, ohne dass die Wärmeleitfähigkeit des Restgases eine Rolle spielt. So ist bei diesen mikroporösen Materialien nur ein Vakuum von 1 bis 10 mbar notwendig, um die Wärmeleitfähigkeit auf 0,004 bis 0,005 W/mK zu bringen. Umhüllungen aus speziellen Barrierefolien, die nur eine hauchdünne, aufgedampfte Beschichtung aus Aluminium aufweisen, stellen sicher, dass der Gasdruck im Kernmaterial nur mit etwa einem mbar pro Jahr ansteigt.Core plates of microporous silica powder have a very fine pore structure and allow relatively high gas pressures, without the thermal conductivity of the residual gas plays a role. Thus, with these microporous materials only a vacuum of 1 to 10 mbar is necessary to bring the thermal conductivity to 0.004 to 0.005 W / mK. Casings made of special barrier films, which have only a very thin, vapor-deposited coating of aluminum, ensure that the gas pressure in the core material only increases by about one mbar per year.
Im zuvor ausführlich erläuterten Stand der Technik werden verschiedene Maßnahmen zur Herstellung von Vakuumisolationspaneelen der in Rede stehenden Art beschrieben. Insbesondere wird auch erläutert, dass der flächige Kern nicht nur einteilig, sondern auch mehrteilig aufgebaut sein kann.In the prior art explained in detail above, various measures for the production of vacuum insulation panels of the type in question are described. In particular, it is also explained that the planar core can not only be constructed in one piece, but also in several parts.
Umfangreiche Vorschläge werden für die Ausgestaltung der Umhüllung mit den Barrierefolien gemacht. Typische erreichbare Gasdurchlässigkeiten und Wasserdampfdurchlässigkeiten werden beschrieben und es werden Vorschläge für die Auswahl der Materialien für die Barriereschichten und die Siegelschichten gemacht.Extensive proposals are made for the design of the enclosure with the barrier films. Typical achievable gas permeabilities and water vapor permeabilities are described, and proposals are made for the selection of materials for the barrier layers and the seal layers.
Alle diesbezüglichen Aussagen im Stand der Technik sollen auch für die vorliegende Erfindung in entsprechender Weise Anwendung finden, soweit die nachfolgenden Ausführungen dem nicht ausdrücklich entgegenstehen. Somit wird für die diesbezüglichen Aussagen umfassend auf den Offenbarungsgehalt der
Vakuumisolationspaneele der in Rede stehenden Art haben hervorragende Dämmeigenschaften. Aufgrund der geringen Dicke der Umhüllung sind Vakuumisolationspaneele der in Rede stehenden Art in der Handhabung aber empfindlich. Man muss darauf achten, dass die Umhüllung des Vakuumisolationspaneels nicht beschädigt wird.Vacuum insulation panels of the type in question have excellent insulation properties. Due to the small thickness of the envelope are vacuum insulation panels of the type in question in handling but sensitive. Care must be taken that the envelope of the vacuum insulation panel is not damaged.

Hohe Brandschutzanforderungen der diesbezüglichen Einsatzgebiete können von den aus dem voranstehend erläuterten Stand der Technik entnehmbaren Vakuumisolationspaneelen nicht erfüllt werden.For certain applications, for example in construction or in vehicle construction, certain fire protection requirements must be met. High fire protection requirements of the relevant applications can not be met by the removable from the above-mentioned prior art vacuum insulation panels.
Der Lehre liegt daher das Problem zugrunde, ein Vakuumisolationspaneel der in Rede stehenden Art anzugeben, das höhere Brandschutzanforderungen erfüllt als die zuvor beschriebenen bekannten Vakuumisolationspaneele, insbesondere wesentlich höhere Brandschutzanforderungen wie sie beispielsweise in der Automobilindustrie vorliegen.The teaching is therefore based on the problem of specifying a Vakuumisolationspaneel of the type in question, which meets higher fire protection requirements than the previously described known vacuum insulation panels, in particular much higher fire protection requirements such as those in the automotive industry.
Die zuvor aufgezeigte Aufgabe ist bei einem Vakuumisolationspaneel mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Bevorzugte Ausgestaltungen und Weiterbildungen sind Gegenstand der Unteransprüche 2 bis 7.The above-mentioned object is achieved in a vacuum insulation panel having the features of the preamble of
Gegenstand der Erfindung ist auch eine Umhüllungsfolie für Vakuumisolationspaneele für sich, die entsprechend hohe Brandschutzanforderungen erfüllt. Insoweit wird auf die Ansprüche 8 bis 10 verwiesen.The invention also provides a wrapping film for vacuum insulation panels for themselves, which meets high fire protection requirements. In that regard, reference is made to the claims 8 to 10.
Erfindungsgemäß wird eine wärmeresistente Ausgestaltung der Umhüllung des Vakuumisolationspaneels nicht durch eine Mischung des Materials einer äußeren Schicht mit hitzebeständigen und/oder flammhemmenden Zusätzen realisiert. Vielmehr wird eine eigenständige Schutzschicht aus einem wärmeresistenten Material auf die Barriereschicht oder die auf der Barriereschicht außen befindliche Zwischenschicht aufgebracht. Es handelt sich um eine spezielle Schutzschicht, die in auf ihre Brandschutzwirkung hin optimiert ist.According to the invention, a heat-resistant embodiment of the envelope of the vacuum insulation panel is not realized by a mixture of the material of an outer layer with heat-resistant and / or flame-retardant additives. Rather, an independent protective layer of a heat-resistant material is applied to the barrier layer or the intermediate layer located on the barrier layer outside. It is a special protective layer that is optimized for its fire protection effect.
Für die Umhüllung im Übrigen, außer der erfindungsgemäß hinzutretenden wärmeresistenten Schutzschicht, gelten die Varianten, die im zuvor ausführlich behandelten Stand der Technik angegeben worden sind, so dass auf den Stand der Technik insgesamt verwiesen werden darf.For the wrapping, moreover, except for the heat-resistant protective layer added according to the invention, the variants which have been specified in the prior art described in detail above apply, so that reference may be made to the state of the art as a whole.
Vakuumisolationspaneele der in Rede stehenden Art können unterschiedliche Formen haben. Die Regelform ist eine flach-plattenförmige Gestaltung. Vakuumisolationspaneele sind aber auch in anderen Formen, beispielsweise gebogen oder abgewinkelt oder mit unterschiedlichen Dicken in unterschiedlichen Abschnitten bekannt. Die vorliegende Erfindung gilt für alle Formen von Vakuumisolationspaneelen.Vacuum insulation panels of the type in question can have different shapes. The rule form is a flat-plate-like design. However, vacuum insulation panels are also known in other forms, for example bent or angled or with different thicknesses in different sections. The present invention applies to all forms of vacuum insulation panels.
Erfindungsgemäß ist die wärmeresistente Schutzschicht in zumindest einem Bereich der Außenfläche des Vakuumisolationspaneels außen aufgebracht. Eine einseitige Aufbringung der Schutzschicht reicht bei einem Vakuumisolationspaneel aus, das in einer bestimmten Orientierung eingebaut wird. Bevorzugt ist es allerdings, dass die komplette Umhüllung mit der wärmeresistenten Schutzschicht versehen ist, so dass es gleichgültig ist, in welcher Orientierung das erfindungsgemäße Vakuumisolationspaneel eingebaut wird.According to the invention, the heat-resistant protective layer is applied externally in at least one region of the outer surface of the vacuum insulation panel. One-sided application of the protective layer is sufficient with a vacuum insulation panel installed in a certain orientation. It is preferred, however, that the complete enclosure is provided with the heat-resistant protective layer, so that it does not matter in which orientation the vacuum insulation panel according to the invention is installed.
Die wärmeresistente Schutzschicht kann dadurch auf die Barriereschicht oder die außen auf der Barriereschicht befindliche Zwischenschicht aufgebracht werden, dass der Werkstoff der wärmeresistenten Schutzschicht in situ aufgebracht wird. Bevorzugt ist es allerdings, weil sich dadurch eine bessere Handhabung ergibt, dass die wärmeresistente Schutzschicht als eigenständig handhabbare Folie ausgeführt und mit der Umhüllung im Übrigen durch Klebung dauerhaft verbunden ist.The heat-resistant protective layer can be applied to the barrier layer or the intermediate layer located on the outside of the barrier layer in such a way that the material of the heat-resistant protective layer is applied in situ. It is preferred, however, because this results in a better handling, that the heat-resistant protective layer is designed as independently handleable film and permanently connected to the enclosure by gluing otherwise.
Klebung im Sinne der Lehre der vorliegenden Erfindung schließt die Verwendung von zusätzlichen Klebemitteln ein, umfasst aber auch die Verwendung von Schmelzklebern, insbesondere Heißschmelzklebern, oder das Verschweißen durch Anschmelzen des Materials der wärmeresistenten Schutzschicht und/oder der Barriereschicht und/oder der Zwischenschicht selbst zum Zwecke der Verbindung miteinander. Auch die Verwendung eines doppelseitigen Klebebandes oder einer klebefähigen Beschichtung fällt unter diese Definition.Bonding in accordance with the teachings of the present invention involves the use of additional adhesives, but also includes the use of hot melt adhesives, particularly hot melt adhesives, or welding by fusing the material of the heat resistant protective layer and / or the barrier layer and / or the intermediate layer itself to the purpose the connection with each other. The use of a double-sided adhesive tape or an adhesive coating is also covered by this definition.
In einer ersten besonders bevorzugten Ausführungsform ist nun vorgesehen, dass die wärmeresistente Schutzschicht im Wesentlichen aus mit einem Bindemittel fixierten Glimmerpartikeln, insbesondere auf Basis von Phlogopit oder Muskovit, besteht. Man bezeichnet das auch als „Kunstglimmer“ (siehe beispielsweise Schröcke, Weiner „Mineralogie“, Walter de Gruyter, 1981, sowie Wikipedia, Stichwort „Kunstglimmer“). Im englischsprachigen Raum bezeichnet man derartige Werkstoffe auf Basis von Glimmer auch als „Mica-Werkstoff“ oder „Mica-Folie“ (Wikipedia, Stichwort „Mica“ sowie Stichworte „Phlogopit“ und „Muskovit“).In a first particularly preferred embodiment, it is now provided that the heat-resistant protective layer essentially consists of mica particles fixed with a binder, in particular based on phlogopite or muscovite. This is also referred to as "art mica" (see, for example, Schröcke, Weiner "mineralogy", Walter de Gruyter, 1981, and Wikipedia, keyword "art mica"). In English-speaking countries, such materials are referred to Base of mica as "mica material" or "mica foil" (Wikipedia, keyword "mica" and keywords "phlogopite" and "muscovite").
Schichten im Wesentlichen aus mit einem Bindemittel fixierten Glimmerpartikeln werden im Stand der Technik bereits eingesetzt, beispielsweise als Trägermaterial für Heizdrähte oder Flächenheizelemente. Vorliegend wirken sie andersartig, nämlich zum Schutze des von ihnen abgedeckten Werkstoffes, zum Schutze des Vakuumisolationspaneels insgesamt.Layers essentially of mica particles fixed with a binder are already used in the prior art, for example as a carrier material for heating wires or surface heating elements. In the present case they act differently, namely to protect the material covered by them, to protect the vacuum insulation panel as a whole.
Im Sinne einer optimierten Handhabung ist insoweit eine bevorzugte Ausführungsform dadurch gekennzeichnet, dass die Glimmerpartikel der wärmeresistenten Schutzschicht auf einem flächigen Trägermaterial, insbesondere auf einem Glasfasergewebe oder -gewirke oder auf einer Kunststofffolie, insbesondere einer PET-Folie, aufgebracht und fixiert sind. Ein Glasfasergewebe oder -gewirke kommt insbesondere für Phlogopit, eine PET-Folie insbesondere für Muskovit als Trägermaterial in Frage. Auf diese Weise lassen sich die plättchenartigen Glimmerpartikel mit ihrem Bindemittel gut handhaben.In the sense of optimized handling, a preferred embodiment is characterized in that the mica particles of the heat-resistant protective layer are applied and fixed on a flat carrier material, in particular on a glass fiber fabric or knitted fabric or on a plastic film, in particular a PET film. A glass fiber fabric or knitted fabric is particularly suitable for phlogopite, a PET film in particular for muscovite as a carrier material in question. In this way, the platelet-like mica particles can be handled well with their binder.
Als Bindemittel kommen primär Kunstharze verschiedener Provenienz oder Kunstkautschuk in Frage, die aus dem Stand der Technik bekannt sind (z.B. Kontaktkleber auf Basis SBR-Styrol-Butadien-Rubber; z.B. Handelsname „GLUKON“).Suitable binders are primarily synthetic resins of various provenances or synthetic rubber known in the art (e.g., SBR styrene butadiene rubber based contact adhesive, e.g., trade name "GLUKON").
Für die wärmeresistente Schutzschicht im Wesentlichen aus mit einem Bindemittel fixierten Glimmerpartikeln empfehlen sich eine Dicke in der Größenordnung von 20 µm bis 300 µm, vorzugsweise von 50 µm bis 150 µm. Das ist für die typischen Brandschutzanforderungen der vorliegenden Art ausreichend.For the heat-resistant protective layer consisting essentially of mica particles fixed with a binder, a thickness of the order of magnitude of 20 μm to 300 μm, preferably of 50 μm to 150 μm, is recommended. This is sufficient for the typical fire protection requirements of the present type.
In einer Alternative kann man auch vorsehen, dass die wärmeresistente Schutzschicht im Wesentlichen aus einem bei Wärmeeinwirkung aufschäumenden Material besteht. Eine wärmedämmende Schutzschicht dieser Art ist aus dem Stand der Technik auch als Brandschutzfolie bekannt (thermoplastische Polyolefine, gefüllt mit anorganischen Flammschutzmitteln, z.B. Alkalisilikat, z.B. Handelsname „Cello HL Firestop R“).In an alternative, it can also be provided that the heat-resistant protective layer essentially consists of a material that foams up on exposure to heat. A heat-insulating protective layer of this kind is also known in the art as a fire-resistant film (thermoplastic polyolefins filled with inorganic flame retardants, e.g., alkali silicate, e.g., trade name "Cello HL Firestop R").
Bei dem zuvor erläuterten Ausführungsbeispiel bedarf es größerer Dicken um eine entsprechende Brandschutzwirkung zu erzielen, nämlich einer Dicke von ca. 0,5 mm bis 5 mm, vorzugsweise von 2 mm bis 3 mm.In the embodiment described above, it requires larger thicknesses to achieve a corresponding fire protection effect, namely a thickness of about 0.5 mm to 5 mm, preferably from 2 mm to 3 mm.
Gegenstand der Erfindung ist auch eine Umhüllungsfolie für Vakuumisolationspaneele als solche mit den zuvor beschriebenen Eigenschaften, wozu auf die Ansprüche 11 bis 13 verwiesen werden darf.The invention also provides a wrapping film for vacuum insulation panels as such having the properties described above, to which reference may be made to claims 11 to 13.
Im Folgenden wird die Erfindung anhand einer lediglich Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Im Zuge der Erläuterung der Ausführungsbeispiele werden auch besonders bevorzugte Varianten und Modifikationen der Lehre der Erfindung beschrieben.In the following the invention will be explained in more detail with reference to a drawing illustrating only embodiments.
