Description
Die Erfindung betrifft die Kontaktierung von Flächenheizleitern aus elektrisch leitend gemachten! Kunststoff. -Um elektrisch leitende Kunststoff-Foli.en als Flächenheizleiter verwenden zu kÖnnen, ist es erforderlich, daß bei einer beispielsweise rechteckigen oder quadratischen "Heizfolie"- ein Stromzufluß zwischen zwei einander gegenüberliegenden Seiten erfolgen kann, also die gesamte Folienfläche als elektrischer Leiter-zur Wärmeentwicklung ausgenutzt wird.The invention relates to the contacting of surface heating conductors made electrically conductive! Plastic. -To electrically conductive plastic foils to be able to use as a surface heating conductor, it is necessary that for example rectangular or square "heating foil" - a flow of electricity between two each other opposite sides can take place, so the entire film surface as electrical Head-is used for heat generation.
Die Voraussetzung für einen gleichmäßigen Stromfluss über die gesamte Heizleiterfläche bildet neben der Gleichmäßigkeit des Fl@;.cienheizleiters selbst hinsichtlich der Schichtdicke und der gleichmäßigen Verteilung des in den Kunststoff eingearbeiteten Leitpiimentes eine einwandfreie Kontaktierung der stromzuführenden Elektroden mit dem leitend gemachten iCunststo@ff über die ganze Länge der zu kontaktierenden Feizleiterseite. Es sind Kontaktierungs-' mäglichkeiten-für flexible elektrische Leiter, wie sie di-e leitende Kunststoff-Folie uoA. darstellt, bekannt, wie z.B. dünne Metallbleche, Fäden oder Litzen:, vorzugsweise aus iLupfer,_Silber oder Aluminium, die auf den Flächenheizleiter aufgenäht oder darin eingewirkt wer-, den. Auch werden ivetallpulver zur liontaktierung mit einem geeigneten-Bindemittel als-elektrisch leitende Farbe aufgezeichnet oder aufgesprüht wie z.B. Leitsilber, oder schmelzflüssiges Aletall aufgest:iubt .eie z.ß. flüssiges Zink, iras aber nur bei thermisch sehr unempfindlichen Kunststoffen aneiwendet werden kann.The prerequisite for an even flow of current over the entire In addition to the uniformity of the surface, the heating conductor surface forms the heating conductor itself regarding the layer thickness and the even distribution of the in the plastic incorporated Leitpiimentes a perfect contacting of the current-carrying Electrodes with the conductive iCunststo @ ff over the entire length of the Feizleiterseite. There are contacting possibilities for flexible electrical Ladder, as they do the conductive plastic film and others. is known, e.g. thin metal sheets, threads or strands:, preferably made of iLupfer, _silver or aluminum, which are sewn onto the surface heating conductor or worked into it. Also be ivetallpulver for lion clocking with a suitable-binder as-electric Conductive paint recorded or sprayed on such as conductive silver, or molten liquid Aletall aufgest: iubt .eie z.ß. liquid zinc, iras only for thermally very insensitive ones Plastics can be applied.
Bei allen oben angef; hrten i%ontektieriin,;sarten tritt eine gewisse St7ranfiilligkeit durch unvoll'-zommene nontaktierung oder begrenzte italtbar:@eit rauf. So könne.: bei aiifenä hten :.:etallstreifen Kontaktlücken zwischen den ::adelstichen entstehen, auch bei eingewirkten h:etallfäden ist nur ein lockerer 1.ontakt mit dem Flächenheizleitervvorhanderi. Am besten ersc::eint noch, aa fi'r thermoplastische Kunststoffe das Aufsprühen von flüssigem Zink nicht in Fra-.e kommt, die :,ontaktierung; durch Leitsilber. Aber mich liier ist die Haltbarkeit der i,oritakte begrenzt durch die mehr oder nreniger gute ii'aftung der aufhetriimenen Schicht und die mit der Zeit einsetzende üxydation des Silbers an der überfläche.With all of the above; Hearing i% onectieriin,; sarten occurs a certain Discrepancy due to incomplete contact or limited contact up. So could .: with aiifenä hten:.: Metal strips contact gaps between the :: needle stitches arise, even with interwoven h: metal threads are only a loose 1st contact with the surface heating conductor available. It would be best to join forces, aa for thermoplastics Plastics the spraying of liquid zinc does not come into question that:, contacting; through conductive silver. But for me, the shelf life of the i, oritakte is limited by the more or less good adhesion of the applied layer and the one with the Time-based oxidation of the silver on the surface.
Um diese ätöranfbllimkeit ausluscitalten und damit die Jetriebssicherheit der Flächenheizleiter zu erhöhen, wird erfindungsgemäß vorgeschlagen, die Stromzuführung mit dem leitend gemachten Kunststoff zu umhüllen. Bei kalt- oder warmhärtenden :unststoffen geschieht das in der ':;eise, dafi man die abisolierten Kabellitzen oder auch glatte oder perforierte Letallbleche, die mit den Stromzuführungen verlötet sind, in den noch flüssigen oder plastischen leitend gemachten iiunststoff eingebettet und übersichichtet und dieser dann erst gehärtet wird.In order to exclude this susceptibility to oil and with it the operational safety To increase the surface heating conductor is proposed according to the invention, the power supply to encase with the plastic made conductive. For cold or warm curing: plastic This happens in the following way: the stripped cable strands or even smooth ones or perforated metal sheets that are soldered to the power supply lines in the still liquid or plastic, made conductive, embedded and overlaid and this is only then hardened.
Bei thermoplastischen Kunststoffen können die :ietalllitzen in die fertigen Flächenheizleiter durch :oärmeeinwirkung (Ilochfrequeriz-oder Joulesche Wärme) in die erweichende Kunststoffmasse so eingeschweißt werden, daß die Stromzuführungen ganz oder zum grössten-'feil von dem leitenden Kunststoff umgeben werden. Besonders guter Kontakt ergibt sich dann, wenn die zu kontaktierenden Stellen des lleizleiters zuvormit Leitsilber bestrichen wird. Anderseits können die Stromzuführungen auch bei der Produktion der lleizleiter, z.B. lleizfolie, sei es bei der Extrusion oder bei der Kalandrierung , in den noch nicht erstarrten, plastischen Kunststoff mit einlaufen. Es läßt sich auf diese Weise erreichen, daß schon bei der Produktion einer bestimmten Heizfolientype diese mit dem für ihre spätere Anwendung geeigneten Kontaktabstand fortlaufend ausgerüstet werden kann.In the case of thermoplastics, the metal strands can be inserted into the finished surface heating conductor by: thermal influence (Ilochfrequeriz or Joulesche Heat) are welded into the softening plastic mass so that the power supply lines be completely or for the greatest part surrounded by the conductive plastic. Particularly Good contact results when the points of the lead manager to be contacted is coated beforehand with conductive silver. On the other hand, the power supply lines can also in the production of the lleizleiter, e.g. lleizfolie, be it during extrusion or during calendering, in the not yet solidified, plastic plastic with come in. In this way it can be achieved that already during production a certain type of heating foil with the one suitable for your later application Contact spacing can be equipped continuously.
Bei beiden für thermoplastische Kunststoffe in Frage kommenden Methoden kann nun die Äietallitze (oder anders geformter metallischer Leiter) entweder blank oder bereits mit leitendem Kunststoffumhüllt mit dem Heizleiter kontaktiert werden. Die Umhüllung mit leitend gemachtem Kunststoff kann in einfacher -ileise in einem Kabeliaoler-#xtruder erfolg=en.In both of the methods that can be used for thermoplastics, the electrical wire (or a differently shaped metallic conductor) can now be contacted with the heating conductor either bare or already encased in conductive plastic. The sheathing with plastic made conductive can be done in a simple -ileise in a Kabeliaoler- # xtruder.
Die Anzahl der bei der Produktion einer Heizfolie mit einlaufenden Zuleitungen richtet sich nach den Misprüchen, die an die Wärmerebulierbarkeit der Folie gestellt werden.The number of incoming heating foils during the production Supply lines are based on the misunderstandings that apply to the heat regulation of the Slide.
