Abstract

The one-sided self-adhesive insulating tape useful for expansion joints, sealings or prefabricated parts, consists of pre-compressed, impregnated polyurethane-soft foam, which is transferred with particles from electrically conducting material.

Description

Die Erfindung bezieht sich auf ein Dichtungsband aus vorkomprimiertem, imprägniertem Polyurethan-Weichschaum.The The invention relates to a precompressed, impregnated flexible polyurethane foam.

Ein derartiges Dichtungsband ist im Handel unter dem Namen "Kompriband" erhältlich. Dieses Band ist selbstquellend und passt sich allen Flächenformen an. Solange dieses Dichtungsband auf einer Rolle ist, ist es im komprimierten Zustand. Im komprimierten Zustand weist dieses Band ein Viertel seiner Höhe im Endstadium auf. Dieses Dichtungsband wird bei Dehnfugen, Abdichtungen, Fertigbauteilen, Asbestzementteilen, Fenster- und Türanschlüssen, Trennwänden, usw. verwendet. Bei der Verarbeitung dieses Dichtungsbandes muss eine Fuge nur grob gereinigt werden und frei von Bitumen, Schalölen und trocken sein. Danach wird das Schutzpapier vom Dichtungsband entfernt und dieses Band 2 mm bis 4 mm "rückversetzt" in die Fuge eingeklebt. Mittels des Klebebands wird dieses Dichtungsband in der Fuge fixiert.One Such sealing tape is commercially available under the name "Kompriband" available. This band is self-swelling and fits all surface forms. As long as this sealing tape on a roll is in a compressed state. In the compressed Condition, this band has a quarter of its height in the final stage on. This sealing tape is used for expansion joints, seals, prefabricated components, Asbestos cement parts, window and door connections, dividing walls, etc. used. When processing this sealing tape must a joint are only roughly cleaned and free of bitumen, formwork oils and be dry. Thereafter, the protective paper from the sealing tape removed and this band 2 mm to 4 mm "set back" in glued in the joint. By means of the adhesive tape is this sealing tape fixed in the joint.

Aus der DE 197 04 226 A1 ist ein Elektromotor mit vorgeschaltetem Frequenzumrichter bekannt. Bei diesem Umrichtermotor wird eine thermische Entkopplung zwischen Frequenzumrichter und Elektromotor dadurch erhalten, dass zwischen dem Gehäuse des Frequenzumrichters und den Kühlkörpern eine Wärmesperre vorgesehen ist. Dadurch wird ein Wärmetransport vom Elektromotor zum Frequenzumrichter reduziert. In einer weiteren Ausführungsform dieses Umrichtermotors ist zwischen dem Gehäuse des Frequenzumrichters und dem Kühlkörper und/oder einem Zwischenteil zumindest eine Feuchtigkeitssperre vorgesehen. Vorzugsweise bilden die Wärmesperren und die Feuchtigkeitssperren eine Funktionseinheit. Das heißt, jede Wärmesperre ist derart ausgeführt, dass sie auch eine Dichtung in hoher Schutzart darstellt, wie eine Dichtung gegen Kontaktkorrosion, Eindringen von Schmutz, Staub, Flüssigkeiten und/oder Wasser. Dadurch, dass diese Wärmesperre mehrere Funktionen in sich vereint, können Teile, zumindest eine Feuchtigkeitssperre, eingespart werden.From the DE 197 04 226 A1 is an electric motor with upstream frequency converter known. In this inverter motor, a thermal decoupling between frequency converter and electric motor is obtained by providing a thermal barrier between the housing of the frequency converter and the heat sinks. This reduces heat transfer from the electric motor to the frequency converter. In a further embodiment of this converter motor, at least one moisture barrier is provided between the housing of the frequency converter and the heat sink and / or an intermediate part. Preferably, the thermal barriers and the moisture barriers form a functional unit. That is, each thermal barrier is designed to also provide a high protection seal, such as a contact corrosion sealant, dirt, dust, liquid, and / or water seal. The fact that this thermal barrier combines several functions in itself, parts, at least one moisture barrier, can be saved.

Gemäß der DIN 40 050 ist der Schutzgrad für den Berührungs- und Fremdkörperschutz in sechs Gruppen und der Schutzgrad für den Wasserschutz in acht Gruppen unterteilt. Gemäß dem Auszug aus DIN 40 050 werden Schutzarten durch ein Kurzzeichen, bestehend aus zwei Kennbuchstaben I und P, und zwei Ziffern angegeben. Die erste Ziffer gibt den Schutzgrad für den Berührungs- und Fremdkörperschutz und die zweite Ziffer den Schutzgrad für den Wasserschutz an. Beispielsweise ist eine Vorrichtung in der Schutzart IP 56 gegen schädliche Staubablagerungen und gegen starken Wasserstrahl geschützt.According to the DIN 40 050 is the degree of protection for the contact and foreign body protection in six groups and the degree of protection for water conservation divided into eight groups. According to the Excerpt from DIN 40 050 are protection types by a code, consisting of two code letters I and P, and two digits indicated. The first digit indicates the degree of protection for the contact and foreign body protection and the second digit the degree of protection for the water protection. For example, a device is in the degree of protection IP 56 against harmful dust deposits and protected against strong water jet.

Soll nun eine Vorrichtung, beispielsweise ein Gehäuse eines Umrichtergerätes, auch noch elektromagnetisch verträglich ausgeführt sein, so muss neben einer Feuchtigkeitssperre auch noch eine EMV-Sperre verwendet werden. Zwischen zwei Gehäuseteilen, beispielsweise Aufnahmeteil und Deckel, muss eine Feuchtigkeitssperre und eine EMV-Sperre angeordnet und diese beiden Gehäuseteile lösbar miteinander verbunden werden. Wenn, wie aus der DE 197 04 226 A1 bekannt ist, zwei Sperren mittels einer Sperre verwirklicht werden können, so kann eine Sperre eingespart werden und damit der Montageaufwand verringert werden. Entgegen der DE 197 04 226 A1 müsste die Feuchtigkeitssperre außerdem die Funktion "EMV-Dichtigkeit" aufweisen.If now a device, such as a housing of a converter, even be designed to be electromagnetically compatible, then in addition to a moisture barrier and an EMC lock must be used. Between two housing parts, such as receiving part and cover, a moisture barrier and an EMC barrier must be arranged and these two housing parts are releasably connected together. If, as from the DE 197 04 226 A1 is known, two locks can be realized by means of a lock, so a lock can be saved and thus the assembly costs are reduced. Contrary to the DE 197 04 226 A1 In addition, the moisture barrier should have the function "EMC tightness".

Der Erfindung liegt nun die Aufgabe zugrunde, ein Dichtungsband derart weiterzubilden, dass dieses Dichtungsband einerseits eine Feuchtigkeitssperre und andererseits eine EMV-Sperre verwirklicht.Of the The invention is based on the object, a sealing strip such to further develop that this sealing tape on the one hand a moisture barrier and on the other hand realized an EMC barrier.

Diese Aufgabe wird mit dem kennzeichnenden Merkmal des Anspruchs 1 erfindungsgemäß gelöst.These The object is achieved with the characterizing feature of claim 1 according to the invention.

Dadurch, dass der Polyurethan-Weichschaum des Dichtungsbandes mit Partikeln aus elektrisch leitendem Material versetzt ist, wird eine Vorrichtung, die dieses Dichtungsband aufweist, gegen das Eindringen von Schmutz, Staub, Flüssigkeiten und/oder Wasser geschützt und gleichzeitig elektromagnetisch verträglich abgedichtet.Thereby, that the flexible polyurethane foam of the sealing strip with particles is made of electrically conductive material, is a device, having this sealing tape, against the ingress of dirt, Dust, liquids and / or water protected and at the same time electromagnetically sealed.

Damit das Dichtungsband, insbesondere ein einseitig selbstklebendes vorkomprimiertes, imprägniertes Schaumstoffdichtungsband auf Polyurethanbasis, gleichzeitig als EMV-Sperre dienen kann, müssen die Partikel dieses Band derart durchsetzen, dass bei einer Verbindung zweier Teile einer Vorrichtung, insbesondere eines Gehäuses eines Umrichters, diese mittels des Dichtungsbandes elektrisch leitend verbunden sind. Damit diese Partikel untereinander eine elektrische Verbindung herstellen können, bestehen diese Partikel aus elektrisch leitendem Material, beispielsweise aus irgendeinem Metall, insbesondere den Metallen entsprechend den Unteransprüchen 2 bis 4.In order to the sealing tape, in particular a one-sided self-adhesive precompressed, Impregnated polyurethane foam-based sealing tape, can serve as an EMC barrier at the same time, the particles must enforce this band so that when connecting two Parts of a device, in particular a housing of a Inverter, this electrically conductive by means of the sealing strip are connected. So that these particles with each other an electrical Can connect, these particles consist of electrically conductive material, for example of any metal, in particular the metals according to the subclaims 2 to 4.

Da dieses erfindungsgemäße Dichtungsband selbstquellend ist, passt sich dieses Band allen Flächenformen an. Die miteinander zu verbindenden Teile einer Vorrichtung müssen nicht mehr plan geschliffen werden. Es reicht aus, wenn diese Flächen nur grob gereinigt werden und trocken sind. Auf einer umlaufenden Fläche eines Teils der zweiteiligen Vorrichtung wird das erfindungsgemäße Dichtungsband mittels seines einseitigen Klebebandes fixiert. Danach werden diese beiden Teile der Vorrichtung miteinander lösbar befestigt. Das in der Trennfuge dieser beiden Teile der Vorrichtung angebrachte Dichtungsband quillt auf, wodurch diese Vorrichtung spritzwassergeschützt und gleichzeitig EMV-dicht ist.Since this sealing tape according to the invention is self-swelling, this tape adapts to all surface shapes. The parts of a device to be joined together no longer need to be ground flat. It is sufficient if these surfaces are only roughly cleaned and dry. On a circumferential surface of a part of the two-part device, the sealing tape according to the invention is fixed by means of its one-sided adhesive tape. Thereafter, these two parts of the device with releasably secured to each other. The attached in the parting line of these two parts of the device sealing strip swells, whereby this device is splash-proof and at the same time EMC-tight.
