Description

Bahn aus wärmeisolierendem MaterialSheet of heat-insulating material

Die Erfindung betrifft eine Bahn aus wärmeisolierendem Material nach dem Oberbegriff des Anspruchs 1. Darüberhinaus betrifft die Erfindung die Anwendung einer solchen Bahn zur Bildung eines Isolierschlauches.The invention relates to a sheet of heat-insulating material according to the preamble of claim 1. Furthermore, the invention relates to the use of such a sheet for forming an insulating tube.

Bahnen aus wärmeisolierendem Material, welche beispielsweise zur Wärmeisolierung von Fußböden, Wänden und Rohren eingesetzt werden, sind in verschiedensten Ausführungsformen im Handel. Manche dieser Bahnen bestehen aus geschäumten Kunststoffen, andere aus verfilzten Kunststoffäden. Die letztgenannten Bahnen bezeichnet man als Vliese. Die zur Herstellung solcher Vliese verwendeten Kunststoffe gehören beispielsweise zur Gruppe der Polyester. Zur Erzielung einer guten Festigkeit und guter Isolationseigenschaften kann das Vlies durch Nadelwalzen geführt und gepreßt werden.Sheets of heat-insulating material, which are used for example for the thermal insulation of floors, walls and pipes, are available in a wide variety of designs. Some of these sheets are made of foamed plastics, others of matted plastic threads. The latter sheets are called fleeces. The plastics used to produce such fleeces belong to the polyester group, for example. To achieve good strength and good insulation properties, the fleece can be passed through needle rollers and pressed.

Die Wärmeisolationseigenschaften einer derartigen Bahn aus einem Kunststoffvlies sind für viele Anwendungsfälle nicht ausreichend, außerdem ist dessen mechanische Widerstandsfähigkeit gering und es ist empfindlich gegenüber Feuchtigkeit.The thermal insulation properties of such a sheet made of a plastic fleece are not sufficient for many applications, and its mechanical resistance is also low and it is sensitive to moisture.

Es besteht daher die Aufgabe, eine derartige Bahn so weiterzubilden, daß sie bessere Isolationseigenschaften aufweist und widerstandsfähiger ist.The task is therefore to further develop such a track so that it has better insulation properties and is more resistant.

Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sowie ein Anwendungsbeispiel sind den Unteransprüchen entnehmbar.This problem is solved with the characterizing features of claim 1. Advantageous embodiments and an application example can be found in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert, welche zeigen:An embodiment of the invention is explained in more detail below with reference to the accompanying drawings, which show:

Fig. 1 einen Querschnitt durch eine erfindungsgemäße Bahn; und Fig. 1 is a cross-section through a web according to the invention; and

Fig. 2 einen Querschnitt durch ein von einem erfindungsgemäßen Isolierschlauch umgebenes Rohr. Fig. 2 shows a cross-section through a pipe surrounded by an insulating tube according to the invention.

Die in Figur 1 dargestellte Bahn aus wärmeisolierendem Material besteht im wesentlichen aus einem flächigen Kunststoffvhes 3, einer flächig darüber angeordneten Luftpolsterfolie 1 und einer auf der gegenüberliegenden Seite der Luftpolsterfolie 1 angeordneten Aluminiumschicht 2.The sheet of heat-insulating material shown in Figure 1 consists essentially of a flat plastic film 3, a bubble wrap 1 arranged flatly over it and an aluminum layer 2 arranged on the opposite side of the bubble wrap 1.

Das Kunststoffvlies 3 ist in an sich bekannter Weise durch Verfilzen von Polyesterfäden hergestellt und gepreßt sowie mit Hilfe einer Nadelwalze verfestigt. Die Luftpolsterfolie 1 besteht in ebenfalls an sich bekannter Weise aus einem oberen Folienstück 8, einem unterem Folienstück 9 und einer Vielzahl flächig verteilter, im wesentlichen zylindrischer Luftkammern 6, wobei die Mantelflächen dieser Luftkammern 6 einstückig mit den Folienstücken 8 und 9 gefertigt sind, welche die Grundflächen der Luftkammern 6 bilden. Die Verbindung des Kunststoffvlieses 3 mit der Luftpolsterfolie 1 erfolgt durch Kleben, vorzugsweise mit Hilfe eines Schmelzklebers. Auf der dem Kunststoff &ngr; Ii es 3 gegenüberliegenden Seite der Luftpolsterfolie 1 befindet sich eine Metallschicht aus Aluminium, die im Aufdampfverfahren aufgebracht ist und beispielsweise eine Dicke von 20 &mgr;&idiagr;&eegr; aufweist.The plastic fleece 3 is manufactured in a manner known per se by felting polyester threads and pressed and solidified using a needle roller. The bubble wrap 1 also consists in a manner known per se of an upper piece of film 8, a lower piece of film 9 and a large number of flat, essentially cylindrical air chambers 6, the outer surfaces of these air chambers 6 being made in one piece with the pieces of film 8 and 9, which form the base surfaces of the air chambers 6. The plastic fleece 3 is connected to the bubble wrap 1 by gluing, preferably using a hot melt adhesive. On the side of the bubble wrap 1 opposite the plastic fleece 3 there is a metal layer made of aluminum, which is applied using a vapor deposition process and has a thickness of 20 μm, for example.

Gegenüber den eingangs genannten bekannten Isolierbahnen weist diese Bahn den Vorteil auf, daß sie durch die Addition der wärmeisolierenden Wirkung der Luftpolsterfolie 1 und des Kunststoffvlieses 3 eine gute Wärmeisolierung bietet. Verstärkt wird dieser Effekt durch die aufgedampfte Aluminiumschicht, welche insbesondere den Wärmeverlust durch Abstrahlung verhindert. Darüberhinaus weist die isolierbahn eine hohe Widerstandsfestigkeit gegenüber Stoßen und Schlägen auf, da diese von der Luftpolsterfolie 1 absorbiert werden.Compared to the known insulating sheets mentioned at the beginning, this sheet has the advantage that it offers good thermal insulation through the addition of the thermally insulating effect of the bubble wrap 1 and the plastic fleece 3. This effect is reinforced by the vapor-deposited aluminum layer, which in particular prevents heat loss through radiation. In addition, the insulating sheet has a high resistance to impacts and blows, since these are absorbed by the bubble wrap 1.

Ein Anwendungsbeispiel einer erfindungsgemäßen Isolierbahn ist in Figur 2 dargestellt. Darin wurde eine Isolierbahn gemäß Figur 1 um eine zur Zeichenebene senkrechte Achse aufgewickelt und an den aufeinandertreffenden Enden mit sich selbst verbunden, wodurch eine schlauchartige Struktur entsteht. Diese ist in Figur 2 im Querschnitt und um eine Rohrleitung 7 gelegt dargestellt. Die Verbindung der aufeinandertreffenden Enden der Isolierbahn erfolgt an der Stoßkante 4, bei-An example of an application of an insulating sheet according to the invention is shown in Figure 2. In it, an insulating sheet according to Figure 1 was wound around an axis perpendicular to the plane of the drawing and connected to itself at the ends that meet, creating a hose-like structure. This is shown in Figure 2 in cross-section and laid around a pipe 7. The ends of the insulating sheet that meet are connected at the abutting edge 4, at

spielsweise durch Wärmeverschweißen. Verschweißt wird hierbei die aus Kunststoff bestehende Luftpolsterfolie 1 und die aufgedampfte Aluminiumschicht 2. Darüberhinaus kann auch das Kunststoffvlies 3 selbst bei genügender Wärmeanwendung verschweißt werden.for example by heat welding. The plastic bubble wrap 1 and the vapor-deposited aluminum layer 2 are welded together. In addition, the plastic fleece 3 itself can also be welded together if sufficient heat is applied.

Zusätzlich oder anstelle der Wärmeverschweißung kann ein die Stoßkante 4 überdeckendes Klebeband 5 angebracht werden. Dies ist, zusätzlich zur Wärmeverschweißung, insbesondere dann angebracht, wenn die Rohrleitungen 7 nach dem Verlegen nicht mehr zugänglich sind und ein Aufplatzen des Isolierschlauches in jedem Fall verhindert werden muß.In addition to or instead of heat welding, an adhesive tape 5 can be applied covering the joint edge 4. This is particularly appropriate in addition to heat welding if the pipes 7 are no longer accessible after installation and bursting of the insulating hose must be prevented in any case.

In einer alternativen Ausführungsform kann anstelle des Klebebandes 5 auch ein mit der Aluminiumoberfläche des Isolierschlauches verschweißtes Metallband verwendet werden.In an alternative embodiment, a metal tape welded to the aluminum surface of the insulating tube can be used instead of the adhesive tape 5.
