The thickness of the carrier layer is 15 mu m to 2 mm and the insulating layer is 5 mm-7 cm. The strips are arranged in a distance of 1.5-7 cm.

Description

Die vorliegende Erfindung betrifft ein Isolierband mit einer Isolierschicht aus hartem Isolationsmaterial.The present invention relates to an insulating tape with an insulating layer of hard insulating material.

Derartige Isolierbänder besitzen eine Isolierschicht, die üblicherweise auf einer Trägerschicht angebracht ist, und werden speziell zur thermischen Trennung in verschiedenen Einbausituationen im Trapezblech-, Sandwich- und Metallbau verwendet. Ein besonderes Anwendungsgebiet ist die Verhinderung von Kältebrücken zwischen Gebäudeunterkonstruktion und Außenschale. Es kann dabei sowohl im Wand- als auch im Dachbereich eingesetzt werden. Wichtig ist eine hohe Stauchhärte und eine einfache Verarbeitung und Handhabung.Such insulating tapes have an insulating layer, which is usually mounted on a carrier layer, and are used especially for thermal separation in various installation situations in trapezoidal sheet metal, sandwich and metal construction. A special field of application is the prevention of cold bridges between building substructure and outer shell. It can be used both in the wall and in the roof area. Important is a high compression hardness and easy processing and handling.

Aufgrund stetig steigender Anforderungen hinsichtlich der Isolationswerte zum Erzielen einer immer noch geringeren Wärmeleitung müssen derartige Isolierbänder dicker ausgestaltet werden, damit sie den Ansprüchen gerecht werden. Hierbei ist es problematisch, dass zu dicke thermisch entkoppelnde Isolierbänder sich nicht mehr streifenförmig zu Rollen aufwickeln lassen.Due to steadily increasing requirements in terms of insulation values to achieve a still lower heat conduction such insulating tapes must be made thicker, so that they meet the requirements. In this case, it is problematic that too thick thermally decoupled insulating tapes can no longer be wound up into strips in order to form rolls.

Aus der WO 95/33953 ist ein Isolierband mit einer biegeschlaffen Trägerschicht bekannt, das die Merkmale des Oberbegriffs des Anspruchs 1 aufweist.
Aus diesem Dokument ist ein Isolierband für eine Rohrleitung bekannt, das aus einem harten Isoliermaterial besteht, welches auf einer biegeschlaffen Trägerschicht befestigt sein kann. Die Isolierschicht ist in Segmente unterteilt, die derart um das Rohr gewickelt sind, dass eine geschlossene Isolierschicht entsteht.From the WO 95/33953 an insulating tape with a pliable support layer is known, having the features of the preamble of claim 1.
From this document, an insulating tape for a pipeline is known, which consists of a hard insulating material, which may be mounted on a pliable support layer. The insulating layer is divided into segments that are wound around the pipe to form a closed insulating layer.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Isolierband zur thermischen Trennung im Baubereich zu schaffen, das hohe Isolierwerte erzielt und gleichzeitig in Platz sparender Weise gelagert und transportiert werden kann.The present invention has for its object to provide an insulating tape for thermal separation in the construction sector, which achieves high insulation and can be stored and transported in a space-saving manner at the same time.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß weist das Isolierband eine Isolierschicht aus hartem Isolationsmaterial auf, die in vorbestimmten Abständen Einschnitte aufweist, zwischen denen einzelne Segmente der Isolierschicht ausgebildet sind, die miteinander verbunden sind.According to the invention, the insulating tape on an insulating layer of hard insulating material having at predetermined intervals incisions, between which individual segments of the insulating layer are formed, which are interconnected.

Die Trägerschicht weist auf der der Isolierschicht abgewandten Seite eine Selbstklebeeigenschaft auf. In diesem Fall kann die Trägerschicht mit einer Abdeckfolie versehen sein, die vor dem Einbau des Isolierbands abgelöst wird.The carrier layer has a self-adhesive property on the side facing away from the insulating layer. In this case, the carrier layer may be provided with a cover, which is detached prior to installation of the insulating tape.

Dadurch wird gewährleistet, dass auch relativ dicke Isolierschichten auf geeignete Weise Platz sparend gelagert und transportiert werden können, dennoch einen hohen Isolationswert besitzen und einfach haftend mit der Unterlage verbunden werden können.This ensures that even relatively thick insulating layers can be stored and transported in a suitable manner to save space, yet have a high insulation value and can be easily adhered to the pad.

Vorzugsweise ist das Isolierband aus Handhabungsgründen und im Sinne einer Platzersparnis zu einer Rolle aufgewickelt.Preferably, the insulating tape for handling reasons and in terms of space savings wound up into a roll.

Bei dieser Anordnung liegen benachbarte Segmente der Isolierschicht an ihrem unteren Ende eng aneinander und laufen in Richtung ihres oberen Endes auseinander, so dass sich ein sich in Richtung des oberen Endes erweiternder keilförmiger Zwischenraum zwischen den Segmenten ergibt. Auf diese Weise können auch sehr dicke Isolierbänder mit hohen Isolierwerten problemlos im aufgewickelten Zustand gelagert und transportiert werden, ohne die Materialeigenschaften des Isolierbands zu beeinträchtigen.In this arrangement, adjacent segments of the insulating layer are closely adjacent to each other at their lower end and diverge toward their upper end, resulting in a wedge-shaped gap extending between the segments in the direction of the upper end. In this way, even very thick insulating tapes with high insulation values can easily be stored and transported in the wound state without impairing the material properties of the insulating tape.

Zum Erzielen hoher Isolierwerte weist die Isolierschicht in bevorzugten Ausführungsformen Mineralwolle, einen harten Polyurethanschaum, einen harten Polyethylenschaum, einen harten Polypropylenschaum, Presspappe, Holz, Styropor oder ein Hohlkammerprofil aus Kunststoff oder einem anderen Material auf.In order to achieve high insulation values, the insulating layer in preferred embodiments comprises mineral wool, a hard polyurethane foam, a hard polyethylene foam, a rigid polypropylene foam, compressed board, wood, Styrofoam or a hollow chamber profile made of plastic or other material.

Die Segmente sind haftend auf der Trägerschicht angebracht. Als Trägerschicht kommen beispielsweise Vliese, biegeschlaffe Stoffe oder biegeschlaffe Folien sowie Kombinationen hiervon zur Anwendung.The segments are adhesively attached to the carrier layer. The carrier layer used are, for example, nonwovens, pliable substances or pliable films and combinations thereof.

In einer vorteilhaften Ausführungsform weist die Trägerschicht auch auf der der Isolierschicht zugewandten Seite Selbstklebeeigenschaften auf, wodurch auf einfache Weise eine haftende Verbindung zwischen Trägerschicht und Isolierschicht erzeugt wird.In an advantageous embodiment, the carrier layer also on the insulating layer side facing self-adhesive properties, whereby in a simple manner an adhesive bond between the carrier layer and insulating layer is generated.

Die Einschnitte sind vorteilhafterweise in einem Abstand von jeweils zwischen 1 cm und 15 cm, vorzugsweise zwischen 1,5 und 7 cm, angeordnet. Durch Wahl des Größenbereiches können Isolierbänder einer Dicke von 3 mm bis zu mehreren cm, vorzugsweise zwischen 5 mm und 7 cm, problemlos und auf möglichst Platz sparende Weise gelagert und transportiert werden.The incisions are advantageously arranged at a distance of between 1 cm and 15 cm, preferably between 1.5 and 7 cm. By selecting the size range insulating tapes of a thickness of 3 mm to several cm, preferably between 5 mm and 7 cm, can be stored and transported easily and in the most space-saving manner.

Weitere Merkmale, Vorteile und Eigenschaften der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung unter Bezugnahme auf die Zeichnungen:

Further features, advantages and features of the present invention will become apparent from the following description with reference to the drawings:
Fig. 1
is a cross-sectional view of an insulating tape according to the invention in a partially wound into a roll and partially unwound state; and
Fig. 2
is a schematic view of a manufacturing method of the insulating tape according to the invention.

Das in Fig. 1 dargestellte Isolierband ist teilweise in einem zu einer Rolle aufgewickelten Zustand und teilweise in einem abgewickelten Funktionszustand dargestellt. Das Isolierband weist eine Trägerschicht 2 auf, die beispielsweise aus einem Vlies, einem biegeschlaffen Stoff oder einer biegeschlaffen Folie bestehen kann. Auf der Trägerschicht 2 sind haftend Segmente 4 einer Isolierschicht 6 aufgebracht, die durch Einschnitte 5 voneinander getrennt sind. Die Isolierschicht 6 besitzt einen besonders hohen Isolierwert und besteht aus einem harten Isolationsmaterial, beispielsweise Mineralwolle, einem harten Polyurethanschaum, einem harten Polyethylenschaum, einem harten Polypropylenschaum, aus Presspappe, Holz, Styropor oder einem Hohlkammerprofil aus Kunststoff oder einem anderen Material. Im Grunde kann jeder harte, d.h. weitgehend biegesteife und zu Isolationszwecken einsetzbare Stoff verwendet werden.This in Fig. 1 shown insulating tape is partially shown in a wound-up to a roll state and partially in a developed functional state. The insulating tape has a carrier layer 2, which may for example consist of a non-woven, a limp material or a pliable film. On the carrier layer 2 are adhesively applied segments 4 of an insulating layer 6, which are separated by incisions 5 from each other. The insulating layer 6 has a particularly high insulation value and consists of a hard insulation material, such as mineral wool, a hard polyurethane foam, a hard polyethylene foam, a hard polypropylene foam, from pressed cardboard, wood, Styrofoam or a hollow chamber profile made of plastic or other material. Basically, any hard, ie largely rigid and usable for isolation purposes fabric can be used.

Die Dicke der Trägerschicht 2 beträgt vorzugsweise zwischen ca. 15 µm und 2 mm, und die Trägerschicht 2 ist vorzugsweise an ihrer den Segmenten 4 der Isolierschicht 6 zugewandten Seite selbstklebend ausgestaltet, wodurch die Anhaftung der Segmente 4 an der Trägerschicht 2 auf besonders einfache Weise gewährleistet ist. Ebenso besteht bei bestimmten Materialien die Möglichkeit einer thermischen Verbindung durch Verschweißen oder Ultraschall. Um den Einbau des Isolierbands zu vereinfachen, ist die Trägerschicht 2 vorzugsweise auch an ihrer anderen Seite mit Selbstklebeeigenschaften ausgestattet. In diesem Fall ist eine hier nicht dargestellte Abdeckfolie notwendig, die über der selbstklebenden Fläche der Trägerschicht 2 angeordnet ist. Alternativ kann auch die Isolierschicht 6 an ihrer Oberseite z.B. mit einer silikonisierten Folie beschichtet sein, die zur Abdeckung dient, sodass eine separate Abdeckfolie auf der selbstklebenden Trägerschicht 2 nicht erforderlich ist.The thickness of the carrier layer 2 is preferably between about 15 .mu.m and 2 mm, and the carrier layer 2 is preferably designed to be self-adhesive on its side facing the segments 4 of the insulating layer 6, whereby the adhesion of the segments 4 to the carrier layer 2 ensured in a particularly simple manner is. Likewise, there is the possibility of thermal bonding by welding or ultrasound in certain materials. In order to simplify the installation of the insulating tape, the carrier layer 2 is preferably also equipped on its other side with self-adhesive properties. In this case, a cover film, not shown here, is necessary, which is arranged over the self-adhesive surface of the carrier layer 2. Alternatively, the insulating layer 6 may also be provided at its upper side, e.g. be coated with a siliconized film, which serves to cover, so that a separate cover film on the self-adhesive support layer 2 is not required.

Die Segmente 4 der Isolierschicht 6 besitzen eine Dicke von 3 mm bis zu mehreren cm, vorzugsweise zwischen 5 mm und 7 cm, und sind etwa zwischen 1 cm und 15 cm, vorzugsweise zwischen 1,5 und 7 cm lang. Die Breite der einzelnen Segmente 4 und somit des Isolierbands kann nahezu beliebig gewählt werden und ist auf die entsprechenden Anwendungsgebiete zugeschnitten. Typische Breiten der Isolierbänder sind 3 cm bis 20 cm.The segments 4 of the insulating layer 6 have a thickness of 3 mm to several cm, preferably between 5 mm and 7 cm, and are approximately between 1 cm and 15 cm, preferably between 1.5 and 7 cm long. The width of the individual segments 4 and thus of the insulating tape can be chosen almost arbitrarily and is tailored to the respective fields of application. Typical widths of the insulating tapes are 3 cm to 20 cm.

Während die einzelnen Segmente 4 der Isolierschicht 6 im geraden Funktionszustand derart eng aneinanderliegen, dass sie eine geschlossene Isolierschicht 6 bilden, führt die Unterteilung der Isolierschicht 6 zu einzelnen Segmenten 4 im aufgewickelten Zustand des Isolierbands dazu, dass benachbarte Segmente 4 der Isolierschicht 6 an ihrem unteren Ende zusammenstoßen und in Richtung ihres oberen Endes auseinanderlaufen, so dass sich ein sich in Richtung des oberen Endes erweiternder keilförmiger Zwischenraum 8 ergibt.While the individual segments 4 of the insulating layer 6 in the straight state of operation abut each other so closely that they form a closed insulating layer 6, dividing the insulating layer 6 into individual segments 4 in the wound-up state of the insulating strip results in adjacent segments 4 of the insulating layer 6 at their bottom Collide end and diverge towards its upper end, so that there is a widening in the direction of the upper end wedge-shaped gap 8.

Je nach Krümmung des zu einer Rolle aufgewickelten Isolierbands umspannen diese Zwischenräume 8 einen entsprechend großen bzw. kleinen Winkel zwischen den benachbarten Seitenflächen 10 zweier nebeneinander liegender Segmente 4. Dadurch ist es unabhängig von der Dicke der Segmente 4 der Isolierschicht 6 möglich, ohne Beeinflussung der Isolierfähigkeit ein erfindungsgemäßes Isolierband auf Platz sparende Weise zu lagern und zum Einsatzort zu transportieren. Die Rollenform ist dabei meist nicht vollständig rund, da die einzelnen Segmente 4 ab einer bestimmten Dicke bzw. Länge nahezu vollständig biegesteif sind und sich somit viele aneinandergereihte gerade Abschnitte der Isolierbandrolle ergeben, wie es auch aus Fig. 1 ersichtlich ist.Depending on the curvature of the wound into a roll insulating tape span these gaps 8 a correspondingly large or small angle between the adjacent side surfaces 10 of two adjacent segments 4. This makes it possible regardless of the thickness of the segments 4 of the insulating layer 6, without affecting the insulating ability to store an inventive insulating tape in a space-saving manner and to transport to the place of use. The role form is usually not completely round, since the individual segments 4 are almost completely rigid from a certain thickness or length and thus many juxtaposed straight sections of Isolierbandrolle arise, as it also out Fig. 1 is apparent.

Im eingebauten, geraden Funktionszustand liefert das Isolierband einen hervorragenden Isolierwert, der dem Isolierwert einer geschlossenen Isolierschicht entspricht.In the built-in, straight functional state, the insulating tape provides an excellent insulation value, which corresponds to the insulating value of a closed insulating layer.

Ebenso ist es möglich, dass die Einschnitte 5 eine gewisse Breite aufweisen, sodass die einzelnen Segmente 4 auch im Funktionszustand einen vorbestimmten Abstand zueinander besitzen. Neben einer vollständigen Durchtrennung der Isolierschicht 6 kann es auch sinnvoll sein, dünne Stege der Isolierschicht 6 zwischen den einzelnen Segmenten 4 stehen zu lassen, die beim Aufwickeln des Isolierbandes zu einer Rolle entweder durchbrechen oder sich entsprechend verbiegen lassen. In letzterem Fall kann sogar die Trägerschicht 2 entfallen.It is also possible that the sipes 5 have a certain width, so that the individual segments 4 have a predetermined distance from each other even in the functional state. In addition to a complete transection of the insulating layer 6, it may also be useful to leave thin webs of the insulating layer 6 between the individual segments 4, which either break when winding the insulating tape into a roll or can be bent accordingly. In the latter case, even the carrier layer 2 can be omitted.

Das Isolierband kann auch Brandschutzeigenschaften aufweisen.The insulating tape may also have fire protection properties.

In Fig. 2 ist ein mögliches Herstellungsverfahren des erfindungsgemäßen Isolierbands in schematischer Ansicht dargestellt. Die Isolierschicht 6 wird als Plattenware bereitgestellt und auf einem Förderband 12 vorwärts bewegt. Dabei kann die Isolierschicht 6 bereits im Vorfeld zu Längsstreifen beliebiger Breite geschnitten sein. Anschließend wird die Isolierschicht 6 mittels mindestens einer Quersäge 14 in vorbestimmten Abständen durchtrennt, wodurch einzelne Segmente 4 der Isolierschicht 6 gebildet werden. Es können auch mehrere Quersägen 14 verwendet werden, die parallel zueinander in einem vorbestimmten Abstand angeordnet sind. Die Vorwärtsbewegung des Förderbandes 12 und die Betätigung der Quersägen 14 verläuft vorzugsweise getaktet.In Fig. 2 is a possible manufacturing method of the insulating tape according to the invention in schematic view shown. The insulating layer 6 is provided as plate goods and moved forward on a conveyor belt 12. In this case, the insulating layer 6 may already be cut in advance to longitudinal strips of any width. Subsequently, the insulating layer 6 is severed by means of at least one cross saw 14 at predetermined intervals, whereby individual segments 4 of the insulating layer 6 are formed. It is also possible to use a plurality of transverse saws 14, which are arranged parallel to one another at a predetermined distance. The forward movement of the conveyor belt 12 and the operation of the transverse saws 14 preferably runs clocked.

Im Anschluss daran werden die einzelnen Segmente 4 der Isolierschicht 6 an ihrer Unterseite mit der Trägerschicht 2 versehen und haftend an dieser angebracht. Vorzugsweise ist die Trägerschicht 2 hierzu selbstklebend ausgestaltet. Beim Anbringen der Trägerschicht 2 ist es wichtig, dass die einzelnen Segmente 4 der Isolierschicht 6 zumindest in einem Teilbereich exakt aneinander anliegen. Anschließend erfolgt gegebenenfalls eine Verpressung der einzelnen Segmente 4 auf die Trägerschicht 2 mittels einer Pressvorrichtung. In diesem Zustand sind die einzelnen Segmente 4 unmittelbar angrenzend aneinander angeordnet und bilden in Kombination eine geschlossene Isolierschicht 6. Das somit erzeugte Isolierband wird anschließend vorzugsweise zu einer Rolle aufgewickelt und somit in einen geeigneten Lager- und Transportzustand gebracht.Subsequently, the individual segments 4 of the insulating layer 6 are provided on its underside with the carrier layer 2 and adhesively attached thereto. Preferably, the carrier layer 2 is configured for this purpose self-adhesive. When attaching the carrier layer 2, it is important that the individual segments 4 of the insulating layer 6 at least in a partial area exactly abut each other. Subsequently, optionally, a compression of the individual segments 4 on the support layer 2 by means of a pressing device. In this state, the individual segments 4 are arranged directly adjacent to each other and form in combination a closed insulating layer 6. The insulating tape thus produced is then preferably wound into a roll and thus brought into a suitable storage and transport state.

Auf diese Weise wird ein Isolierband geschaffen, das neben hervorragenden Isolierwerten auch die Eigenschaft aufweist, auf einfache und Platz sparende Weise gelagert und transportiert werden zu können.In this way, an insulating tape is created, which in addition to outstanding insulation also has the property to be stored and transported in a simple and space-saving manner.
