Description

Stand der TechnikState of the art

Die Erfindung geht aus von einem Verfahren zum Verbinden von unge­ sinterten Keramikfolien nach der Gattung des Hauptanspruches.The invention is based on a method for connecting non sintered ceramic foils according to the genus of the main claim.

Aus der EP 01 42 992 ist es bekannt, elektrochemische Sensoren da­ durch herzustellen, daß ungesinterte Keramikfolien, die gegebenen­ falls bedruckt sein können, übereinander aufgebracht und zusammen­ laminiert werden. Dieses Verfahren wird bei hohen Temperaturen und unter hohem Preßdruck ausgeführt.From EP 01 42 992 it is known to have electrochemical sensors by making that non-sintered ceramic film, the given if can be printed, applied one above the other and together be laminated. This procedure is carried out at high temperatures and executed under high pressure.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Verfahren mit den Merkmalen des Hauptanspruches hat demgegenüber den Vorteil, daß auf die fertigungstechnisch einfache Weise, ohne Zusatz von Spezialklebstoffen, ein Folienverbund erzeugt wird.The inventive method with the features of the main claim has the advantage that the manufacturing technology simple way, without the addition of special adhesives Foil composite is generated.

Dadurch, daß bei Raumtemperatur und bei niedrigem Preßdruck gearbei­ tet wird, wird vermieden, daß sich die Folien verformen oder beschä­ digt werden und der Energieverbrauch wird verringert. Because it works at room temperature and at low pressure tet is avoided that the foils deform or be damaged be reduced and energy consumption is reduced.  

Weiterhin ist der Materialverbrauch bei dem erfindungsgemäßen Ver­ fahren gegenüber dem Laminieren geringer, weil die Folien nach Be­ darf zugeschnitten werden können, wogegen beim Laminieren immer durchgehende Folien aufgelegt werden müssen.Furthermore, the material consumption in the Ver according to the invention drive less than laminating because the foils according to Be may be cut to size, while laminating always continuous foils must be placed.

Es ist weiterhin besonders vorteilhaft, daß das Material der Hilfs­ schicht sowie des Klebers direkt aus dem Folienmaterial, unter Zu­ satz eines Lösungsmittels, erhalten wird.It is also particularly advantageous that the material of the auxiliary layer and the adhesive directly from the film material, under Zu set of a solvent is obtained.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vor­ teilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Verfahrens möglich. Besonders vorteilhaft ist es, das Folienmaterial zur Herstellung der Hilfsschicht sowie auch des Kle­ bers mit Lösungsmittel zu verdünnen, die den Binder der Keramikstof­ fe besonders gut anlösen. Falls Polyvinylbutyral als Binder einge­ setzt wird, ist es besonders vorteilhaft, 2-Ethyl-Hexanol des Lö­ sungsmittels zu verwenden. Dabei ergibt ein Gewichtsverhältnis des Lösungsmittels zum Folienmaterial von 80 zu 50 für die Hilfsschicht sowie ein Gewichtsverhältnis des Lösungsmittels zum Material der Hilfsschicht von 50 zu 100 optimale Eigenschaften, insbesondere ei­ ne optimale Viskosität.The measures listed in the subclaims provide for partial training and improvements in the main claim specified procedure possible. It is particularly advantageous that Foil material for the production of the auxiliary layer as well as the adhesive bers with solvent to dilute the binder of the ceramic dissolve particularly well. If polyvinyl butyral is used as a binder is set, it is particularly advantageous to 2-ethyl-hexanol of Lö to use solvent. This gives a weight ratio of Solvent to film material from 80 to 50 for the auxiliary layer and a weight ratio of the solvent to the material of the Auxiliary layer from 50 to 100 optimal properties, especially egg ne optimal viscosity.

Die Verbindung der ungesinterten, mit Hilfsschicht und Kleber ver­ sehenen Folien, wird in vorteilhafter Weise mit einer Gummiwalze er­ reicht, wobei ein Druck von etwa 4 bis 5 bar optimal ist.The connection of the unsintered, with auxiliary layer and adhesive ver see foils, he is advantageously with a rubber roller enough, with a pressure of about 4 to 5 bar is optimal.

Beschreibung der AusführungsbeispieleDescription of the embodiments

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels beschrieben. Auf den Keramikträger 11 aus mit Yttriumoxid stabili­ siertem Zirkoniumdioxid einer ersten Folie 10 werden Elektroden 12 und Zuleitungen 13 aus einer Platin-Siebdruckpaste oder einer Cer­ met-Siebdruckpaste mit 60 Vol.-% Platin und 40 Vol.-% Zirkoniumdi­ oxid aufgedruckt. Anschließend kann durch Siebdruck eine Abdeck­ schicht 14 aufgebracht werden, die im wesentlichen aus ZrO2 besteht, um einen mechanischen Schutz der Elektrodenzuleitung zu erreichen.The invention is described below using an exemplary embodiment. On the ceramic substrate 11 from siertem yttria stabili zirconia of a first film 10 electrodes 12 and leads 13 of a platinum-screen printing paste or a cerium met-screen-printing paste with 60 vol .-% of platinum and 40 vol .-% Zirkoniumdi oxide are printed. Subsequently, a cover layer 14 can be applied by screen printing, which essentially consists of ZrO 2 in order to achieve mechanical protection of the electrode lead.

Auf die obere Fläche der ersten Folie, die die aufgedruckten Elek­ troden und gegebenenfalls die Abdeckschicht trägt, wird nun eine etwa 20 µm-Meter dicke Hilfsschicht aufgebracht, insbesondere auf­ gedruckt. Dazu wird zunächst das Material für die Hilfsschicht wie folgt gewonnen: Das Material der porösen Deckschicht 20, das im we­ sentlichen mit Yttriumoxid stabilisiertes Zirkoniumdioxid, Poly­ vinylbutyral als Binder, Dioctylphthalat als Weichmacher und Theo­ bromin als Porenbildner enthält, wird zunächst fein zerschnitten. Der Weichmacher Dioctylphthalat kann durch Dibutylphthalat und/oder Dibutylsebacat ersetzt oder mit den genannten Substanzen vermischt sein. Statt Theobromin können weitere Porenbildner, wie Glas, Kohle oder Ruß eingesetzt werden. Das kleingeschnittene Folienmaterial wird nun mit 2-Ethyl-Hexanol, im Gewichtsverhältnis von 100 zu 80, versetzt, bei Raumtemperatur drei Stunden lang gealtert, und an­ schließend in einer Mörsermühle 11 bis 12 Stunden lang vermischt. Die Viskositätsmessung ergab einen Wert von 15-20 Pa·s. Das so erhaltene Material wird nun teilweise zum Aufdrucken der Hilfs­ schicht verbraucht und teilweise weiter mit Lösungsmittel verdunnt, um das Material für den Kleber zu erhalten.An approximately 20 μm-thick auxiliary layer is now applied to the upper surface of the first film, which carries the printed electrodes and optionally the cover layer, in particular printed on. For this purpose, the material for the auxiliary layer is first obtained as follows: The material of the porous cover layer 20 , which essentially contains zirconium dioxide stabilized with yttrium oxide, poly vinylbutyral as binder, dioctyl phthalate as plasticizer and theobromine as pore former, is first cut finely. The plasticizer dioctyl phthalate can be replaced by dibutyl phthalate and / or dibutyl sebacate or mixed with the substances mentioned. Instead of theobromine, other pore formers such as glass, coal or soot can be used. The finely cut film material is then mixed with 2-ethyl-hexanol, in a weight ratio of 100 to 80, aged at room temperature for three hours, and then mixed in a mortar mill for 11 to 12 hours. The viscosity measurement gave a value of 15-20 Pa · s. The material thus obtained is now partly used for printing the auxiliary layer and partly further diluted with solvent in order to obtain the material for the adhesive.

Dazu wird das Material der Hilfsschicht mit 2-Ethyl-Hexanol im Ge­ wichtsverhältnis 2 zu 1, 30 Minuten lang in einem Propeller-Mischer gerührt.For this purpose, the material of the auxiliary layer is stirred with 2-ethyl-hexanol in a weight ratio of 2 to 1.30 minutes in a propeller mixer.

Eine poröse Schutzschicht 20, die mit Yttriumoxid stabilisiertes Zirkoniumdioxid, Binder, Weichmacher und Porenbildner enthält, die Form eines Plättchens mit den Maßen 65×15×0,2 mm hat und die die zweite Folie des Verbundes darstellt, wird nun mit 20+2 mg des Klebers, beispielsweise mit Hilfe einer Bürste, bestrichen.A porous protective layer 20 which contains zirconium dioxide, binder, plasticizer and pore former stabilized with yttrium oxide, has the shape of a plate with the dimensions 65 × 15 × 0.2 mm and represents the second film of the composite, is now made with 20 + 2 mg of the adhesive, for example with the help of a brush.

Anschließend wird die mit Kleber bestrichene untere Fläche der zwei­ ten Folie auf die die Hilfsschicht tragende, obere Fläche der ersten Folie aufgelegt, und durch Abrollen einer Gummiwalze (30) bei Raum­ temperatur und etwa 4 bis 5 bar verklebt.Subsequently, the lower surface of the second film, coated with adhesive, is placed on the upper surface of the first film, which supports the auxiliary layer, and glued by rolling a rubber roller ( 30 ) at room temperature and about 4 to 5 bar.

Es wird ein fester Verbund erreicht, der sich im anschließenden Sin­ tervorgang bei 1600 bis 1800°C nicht löst. A firm bond is achieved, which in the subsequent sin operation at 1600 to 1800 ° C does not solve.  

Nach einem bevorzugten Ausführungsbeispiel, gemäß Fig. 2, ist die zweite Folie 20 flächenmäßig kleiner als die erste Folie 10 und be­ deckt lediglich den Teil der ersten Folie 10, auf den die Elektroden 12 aufgedruckt sind. Entsprechend muß auch lediglich auf dem gemein­ samen Teil der Folien 10 und 20 die Hilfsschicht 15 auf die Folie 10 und der Kleber auf die untere Fläche der Folie 20 aufgebracht werden.According to a preferred embodiment, according to FIG. 2, the second film 20 is smaller in area than the first film 10 and only covers the part of the first film 10 on which the electrodes 12 are printed. Accordingly, the auxiliary layer 15 must be applied to the film 10 and the adhesive to the lower surface of the film 20 only on the common part of the films 10 and 20 .
