Description
Die Erfindung betrifft einen Überhitzungsschutz für wärmeschrumpfbare Gegenstände, insbesondere für wärmeschrumpfbare Kabelmuffen aus einer wärmefesten Beschichtung, welche auf der der Wärmezuführung zugewandten Oberfläche des schrumpfbaren Gegenstandes aufgebracht ist.The invention relates to overheating protection for heat-shrinkable objects, especially for heat-shrinkable cable sleeves made of a heat-resistant Coating, which on the heat supply Surface of the shrinkable object is applied.
Bei Schrumpfprodukten besteht die Gefahr, daß die Oberflä che der zu schrumpfenden Gegenstände durch die Behandlung mit Wärme, vorzugsweise mit Gasbrennern, beschädigt wird. Deshalb sind bereits verschiedene Schutzvorrichtungen verwendet worden. So ist zum Beispiel eine Schutzman schette (DE-U-91 11 996) bekannt, die aus einem Metallge webe mit hoher Wärmeleitfähigkeit besteht, wobei diese mit einer Heißschmelzkleberfolie beschichtet ist. Dies bedeutet, daß eine zusätzliche Manschette zum Schutz ge gen Überhitzung eingesetzt werden muß.With shrink products there is a risk that the surface surface of the objects to be shrunk by the treatment with heat, preferably with gas burners. That is why various protective devices are already in place been used. For example, a protective man Schette (DE-U-91 11 996) known from a Metallge weave with high thermal conductivity, this is coated with a hot melt adhesive film. This means that an additional sleeve for protection ge against overheating.
Ein wie eingangs erläuterter Überhitzungsschutz geht z. B. aus der DE 92 08 661 U1 oder der DE 37 37 005 A1 hervor.An overheating protection as explained at the beginning is such. B. from DE 92 08 661 U1 or DE 37 37 005 A1.
In der DE-A-37 37 005 wird darauf hingewiesen, daß zum Oberflächenschutz bei schrumpfbaren Muffen eine Schicht aus thermoplastischem Polyethylen über der Schrumpfschicht aufgebracht wird, um damit eine örtliche Überhitzung der Schrumpfschicht zu verhindern. Solche Maßnahmen haben je doch nur bedingt Sinn, da der Grad der "zulässigen Über hitzung" nicht erkennbar ist.In DE-A-37 37 005 it is pointed out that for Surface protection for shrinkable sleeves one layer made of thermoplastic polyethylene over the shrink layer is applied to prevent local overheating of the To prevent shrink layer. Such measures have ever but only to a limited extent, since the degree of "permissible excess heating "is not recognizable.
So sind weiterhin aus der europäischen Patentanmeldung 0 447 633-A2 Temperaturindikatoren bekannt, mit deren Hilfe festgestellt werden kann, wann der durch den Tempe raturindikator erkennbare Temperaturbereich erreicht und durchlaufen wird. Doch ist mit derartigen Maßnahmen kein Überhitzungsschutz der Oberflächen gegeben.So are still from the European patent application 0 447 633-A2 temperature indicators known, with their Help can be determined when by the tempe temperature indicator recognizable temperature range reached and is going through. But there is no such measure Protection against overheating of the surfaces.
Aus dem Informationsprospekt 3M Brandschutzbeschichtung ORGOL FS der Firma 3M geht eine Brandschutzbeschichtung hervor.From the 3M ORGOL FS fire protection coating information brochure 3M produces a fire protection coating.
Aus der DE 36 43 580 A1 ist es bekannt, Kabel äußerlich mit einem Brandschutzanstrich zu versehen.From DE 36 43 580 A1 it is known to externally connect a cable Fire protection paint.
Aufgabe der Erfindung ist nun, einen Überhitzungsschutz für schrumpfbare Gegenstände zu schaffen, der einen geeigneten Schutz für die Oberflächen der schrumpfbaren Gegenstände gewährt. Die gestellte Aufgabe wird mit einem Überhitzungsschutz der eingangs erläuterten Art dadurch gelöst, daß die Beschichtung aus einer Brandschutzfarbe besteht.The object of the invention is to provide protection against overheating to create shrinkable items that provide appropriate protection granted for the surfaces of the shrinkable objects. The task is provided with overheating protection at the beginning explained type solved in that the coating of a Fire protection paint exists.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are in the Subclaims described.
Der Vorteil von einem Überhitzungsschutz gemäß der Erfindung liegt nun darin in erster Linie, daß infolge der Beschichtung mit einer Brandschutzfarbe ein guter Oberflächenschutz für den schrumpfbaren Gegenstand erreicht werden kann. Auf diese Weise kann dem jeweiligen Schrumpfprodukt mehr Wärme zugeführt werden ohne daß eine Beschädigung der Oberfläche eintritt. Die Wärme wird auch gleichmäßiger verteilt, so daß beispielsweise die Aktivierung des Heißschmelzklebers im Inneren der schrumpfbaren Gegenstände besser und gleichmäßiger erfolgt. Außerdem ist von Vorteil, wenn sich der Farbton der Brandschutzfarbe bei Wärmezufuhr ändert, da dann auch gleichzeitig optisch angezeigt wird, daß genügend Wärmezufuhr gewährleistet ist. Dadurch könnte zum Beispiel auch auf einen entsprechenden Temperaturindikator verzichtet werden, doch kann es andererseits auch von Vorteil sein, wenn zusätzliche Temperaturindikatoren beigemischt sind, so daß das Auftreten von kritischen Temperaturbereichen noch besser erkennbar wird. Solche Temperaturindikatoren sind zum Beispiel aus der eingangs bereits genannten europäischen Patentanmeldung 0 447 633-A2 bekannt und können hierfür verwendet werden. Bei Kabelmuffen eignet sich besonders ein Temperaturindikator, der eine Grundzusammensetzung aus 25 g Polyamid 66 oder 4.6; 12,5 g Paraloid B 66 und 20 g 1.1.1.-Trichlorethan oder 2-Butanon enthält. Der Rest besteht aus verschiedenen Füllstoffen und Zusätzen, die je nach Anwendungsfall ausgewählt werden, aber nicht grundsätzlich in ihrer Zusammensetzung für die Indikations wirkung erforderlich sind.The advantage of overheating protection according to the invention is now primarily in that due to the coating with a Fire protection paint a good surface protection for the shrinkable Object can be achieved. In this way, the more heat can be supplied to each shrink product without damage to the surface occurs. The warmth will also distributed more evenly, so that, for example, the activation of the Hot melt glue inside the shrinkable items better and takes place more evenly. It is also an advantage if the The color of the fire protection color changes when heat is added, since then too at the same time it is visually indicated that there is sufficient heat input is guaranteed. This could, for example, also apply to one appropriate temperature indicator can be dispensed with, but it can on the other hand, it can also be advantageous if additional Temperature indicators are added, so that the occurrence of critical temperature ranges becomes even more recognizable. Such Temperature indicators, for example, are already from the beginning European patent application 0 447 633-A2 known and can do this be used. Particularly suitable for cable sleeves a temperature indicator that is a basic composition from 25 g polyamide 66 or 4.6; 12.5 g of Paraloid B 66 and Contains 20 g 1.1.1.-trichloroethane or 2-butanone. The Rest consists of various fillers and additives, which are selected depending on the application, but not basically in their composition for the indications effect are required.
Besonders geeignet für solche Temperaturindikatoren sind Umschlagfarben auf der Basis von organischen Polymeren, wie sie in den beiden vorgenannten Beispielen angegeben sind. Diese Umschlagfarben ändern bei Erreichen der kri tischen Temperatur zwischen 150°C und 300°C, vor zugsweise zwischen 200°C und 300°C jeweils ihre Farben - hier zum Beispiel weiß - bzw. werden transparent, so daß die darunter liegende Oberfläche des geschrumpften Gegen standes sichtbar wird.Are particularly suitable for such temperature indicators Envelope colors based on organic polymers, as stated in the two examples above are. These envelope colors change when the kri is reached table temperature between 150 ° C and 300 ° C, before preferably their colors between 200 ° C and 300 ° C - here for example white - or become transparent so that the underlying surface of the shrunken counter is visible.
Solche organische Polymere sind in erster Linie Polyamide.Such organic polymers are primarily polyamides.
Als Brandschutzfarbe eignet sich am besten eine Disper sionsfarbe, die eventuell mit Zusatz von Wasser je nach Bedarf verdünnbar ist. Eine solche Brandschutzfarbe ist zum Beispiel unter dem Handelsnamen 3M Brandschutzbe schichtung ORGOL FS der Firma 3M bekannt. Zusätzlich kann ein Temperaturindikator eingesetzt werden. Der Schmelzpunkt eines solchen Tempera turindikators liegt bei z. B. etwa 250°C, so daß oberhalb die ser Temperatur eine z. B. zunächst farbliche Beschichtung durchsich tig wird und den Blick auf die Farbe des darunter liegen den geschrumpften Gegenstandes freigibt. A disper is best suited as a fire protection paint sion color, which may depend on the addition of water Is dilutable. Such a fire protection paint is for example under the trade name 3M Brandschutzbe layering ORGOL FS known from 3M. additionally can be a temperature indicator be used. The melting point of such a tempera Turindikers is z. B. about 250 ° C, so that above the water temperature a z. B. first colored coating and look at the color of the underneath releases the shrunk object.
Zusammenfassend wird festgestellt, daß durch die Beschich tung des zu schrumpfenden Gegenstandes mit einer Brand schutzfarbe dessen Oberfläche gegen Überhitzung geschützt werden kann, wobei durch entsprechende Farbänderung eine Erkennung des kritischen Temperaturbereiches möglich ist. Bei zusätzlichen Beimengungen von speziellen Temperatur indikatoren kann zusätzlich zum Überhitzungsschutz durch die Brandschutzfarbe auch eine bessere Anzeige des kriti schen Temperaturbereiches erfolgen.In summary it is found that the Beschich with a fire protective paint whose surface is protected against overheating can be, with a corresponding color change Detection of the critical temperature range is possible. With additional admixtures of special temperature indicators can also be used to protect against overheating the fire protection paint also gives a better display of the kriti temperature range.
Die Erfindung wird anhand einer Figur kurz umrissen.The invention is briefly outlined using a figure.
Die Beschichtungen werden jeweils auf der Außenseite der schrumpfbaren Gegenstände angebracht. Als schrumpfbare Gegenstände kommen zum Beispiel Schrumpfschläuche oder schrumpfbare Kabelmuffen in Betracht, die als Umwickelmuf fen 1 ausgebildet sind und entlang zwei sich gegenüber liegender Längskanten Verschlußelemente in Form von zwei hinterschnittenen Wülsten 5 und einer diese Wülste 5 über greifenden Schiene 6 aufweisen. Die Kabelmuffe 1 besteht aus einer Schicht 2 aus schrumpfbarem Material, wobei die Schrumpfwirkung entweder aus schrumpfbarem Flächenmaterial, aus einem schrumpfbaren Gitter, Gewebe, Gewirke oder Gele ge aus schrumpfbaren Fäden hergeleitet wird. Auf dieser schrumpfbaren Schicht 2 ist auf der Außenseite der Über hitzungsschutz 3 in der beschriebenen Form angeordnet. Im Inneren der Kabelmuffe 1 kann noch zusätzlich eine Schicht 4 aus einem an sich bekannten Heißschmelzkleber teilweise oder über die gesamte Fläche verteilt angeordnet werden.The coatings are applied to the outside of the shrinkable objects. As shrinkable objects are, for example, shrink sleeves or shrinkable cable sleeves, which are designed as Umwickelmuf fen 1 and have two opposing longitudinal edges of closure elements in the form of two undercut beads 5 and one of these beads 5 overlapping rail 6 . The cable sleeve 1 consists of a layer 2 of shrinkable material, the shrinkage effect being derived either from shrinkable sheet material, from a shrinkable grid, woven fabric, knitted fabric or gel from shrinkable threads. On this shrinkable layer 2 on the outside of the heat protection 3 is arranged in the form described. In the interior of the cable sleeve 1 , a layer 4 made of a hot-melt adhesive known per se can additionally be arranged partially or distributed over the entire surface.
Durch die Beschichtung der wärmeschrumpfbaren Gegenstände mit dem Überhitzungsschutz ergeben sich noch weitere Vor teile. So wird dadurch auch die Rißgefahr verringert, da die Oberflächenbelastung für das schrumpfbare Material geringer wird. Es kann z. B. auch dadurch eine höhere Vernetzung des schrumpfbaren Materials zugelassen werden, wo durch die Schrumpfkräfte gesteigert werden. Schließlich läßt sich auch ein gleichmäßigeres Schrumpfen erreichen, da die Wärmezufuhr bzw. Wärmeverteilung während der Bewe gungen mit dem Wärmegerät gleichförmiger erfolgt.By coating the heat-shrinkable objects With the overheating protection, there are still more advantages parts. This also reduces the risk of cracking, since the surface load for the shrinkable material becomes lower. It can e.g. B. This also means greater networking of the shrinkable material, where are increased by the shrinking forces. Finally a more uniform shrinkage can also be achieved, since the heat supply or heat distribution during the movement conditions more uniform with the heater.
