Abstract

In a PVD or CVD process for coating a glass surface, the novelty is that, for forming a gastight constructional and/or optical element comprising two or more spaced wall elements, the peripheral edge of at least one side face of each wall element is bonded with a metallic bond layer. Also claimed are (i) use of the process for prodn. of the constructional and/or optical element; and (ii) a constructional and/or optical element consisting of at least two spaced glass wall elements (2, 3) which are edge-sealed to form a gastight intermediate space (5), the novelty being that the bond layer (4) - coated edge at the periphery of at least one side face of each wall element (2, 3) is coated with a solderable metal as a barrier layer (6) or the barrier layer (6) is formed with a solderable surface at the side opposite from the bond layer (4).

Beschreibung description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Patentanspruches 1. The invention relates to a method according to the preamble of patent claim 1.

Bei dem genannten Vorgehen wird zur Erzielung einer hochwertigen Haftschicht ein neuzeitliches, auf entfernten technischen Anwendungsgebieten eingesetztes Verfahren angewendet, das bisher durch den Entwicklungsrückstand bei der Herstellung von Bau- und/oder Lichtelementen und mangels Erkennung dieses Einsatzgebietes und der erforderlichen Vorausetzungen auf diesem Gebiet keinen Zugang fand. In order to achieve a high-quality adhesive layer, a modern method used in distant technical fields of application is used in the procedure mentioned, which so far has not been accessible due to the development lag in the manufacture of construction and / or lighting elements and the lack of recognition of this field of application and the necessary requirements in this field found.

Es stellte sich an die Erfindung die Aufgabe der Weiterverwendung dieses Verfahrens im Sinne eines rationellen Einsatzes bei der Herstellung von Bau und/oder Lichtelementen der eingangs genannten Art. It was an object of the invention to continue using this method in the sense of rational use in the manufacture of construction and / or lighting elements of the type mentioned.

Unter diesem Aspekt hat die vorliegende Erfindung zu der Lösung der Aufgabe nach dem Kennzeichen des Patentanspruches 1 geführt. In this aspect, the present invention has led to the achievement of the object according to the characterizing part of claim 1.

Dadurch kann die Sperrschicht mit dem gleichen Arbeitsprozess wie die Haftschicht aufgetragen werden, wodurch eine erhebliche Vereinfachung der Fabrikation und eine weiterreichende Verwendung der notwendigen Einrichtungen und Anlagen möglich wird. As a result, the barrier layer can be applied using the same working process as the adhesive layer, which considerably simplifies production and enables the necessary equipment and systems to be used more widely.

Bei der Durchführung des Verfahrens an einem Bau- und/oder Lichtelement der eingangs genannten Art erweist es sich als besonders vorteilhaft, wenn die Sperrschicht aufgrund der an sie gestellten hohen Forderungen, beispielsweise zum Schutz der Haftschicht und als anspruchsvolle Verbindung mit der Dichtung, aus verschiedenen gegenseitig verträglichen und gut legierenden Werkstoffen gebildet werden kann. Dabei kommt es darauf an, dass wenigstens die von der Haftschicht abgewandte Oberfläche oder Lage der Sperrschicht lötbar, ausgebildet ist. When carrying out the method on a structural and / or light element of the type mentioned at the outset, it proves to be particularly advantageous if the barrier layer is composed of different materials on account of the high demands placed on it, for example to protect the adhesive layer and as a demanding connection to the seal mutually compatible and well alloying materials can be formed. It is important that at least the surface or layer of the barrier layer facing away from the adhesive layer is designed to be solderable.

Zur Vermeidung von Spannungen, die zum Los-reissen der verschiedenen Schichten untereinander bzw. der Dichtungsfolie oder Einfassung führen, ist es günstig, wenn die Haft und/oder Sperrschicht sowie die die beabstandeten Wandelemente bzw. Platten dicht einfassende Folie wenigstens annähernd die gleichen Ausdehnungseigenschaften bzw. Ausdehnungskoeffizienten aufweisen wie Glas. In order to avoid tensions that lead to the tearing of the different layers from one another or from the sealing film or border, it is advantageous if the adhesive and / or barrier layer and the film sealingly enclosing the spaced-apart wall elements or plates have at least approximately the same expansion properties or Have coefficients of expansion like glass.

Anschliessend wird die Erfindung anhand eines in der einzigen Figur dargestellten Ausführungsbeispiels erörtert. The invention is then discussed with reference to an embodiment shown in the single figure.

Mit 1 ist ein Bau- und/oder Lichteiement eines Gebäudes ausschnittweise veranschaulicht. Der eine Rand dieses aus zwei Platten 2, 3 gebildeten Bau- und/oder Lichtelementes 1 offenbart eine durch physikalische (PVD) oder chemische (CVD) Abscheidung aus der Gas- bzw. Dampfphase vorgenommene Haftschicht 4 aus einem metallischen Werkstoff, die für eine gasdichte Verbindung zwischen dem aus Glas bestehenden und durch einen Abstand einen evakuierbaren Zwischenraum 5 bildenden Platten 2, 3 vorgesehen ist. 1 shows a section of a construction and / or light element of a building. One edge of this structural and / or light element 1, which is formed from two plates 2, 3, discloses an adhesive layer 4 made of a metallic material, which is used for a gas-tight, by physical (PVD) or chemical (CVD) deposition from the gas or vapor phase Connection between the plates 2, 3, which are made of glass and form an evacuable intermediate space 5, is provided.

Auf diese Haftschicht 4 ist mit dem gleichen Verfahren eine Sperrschicht 6 aufgetragen, die sich als Schutz der Haftschicht 4 eignet. Als Schichtmaterialien haben sich Metalle, Metall-Legierungen, Halbleiter, Metalloxide, diverse Karbide, beispielsweise WC, Nitride, Cermets, Sulfide, Selenide, Telluride etc. entsprechend ihrer beonderen Eigenschaften bewährt. Dabei ist es bedeutend, dass die von der Haftschicht 4 abgewandte Oberfläche oder obere Lage der Sperrschicht 6 lötbar ausgebildet ist, wobei die Sperrschicht 6 aus einem oder mehreren Werkstoffen bestehen kann, die sich einerseits mit der Haftschicht 6 dicht verbinden und die andererseits eine dichte Lötverbindung zur Einfassung der Platten bewerkstelligen lassen. Im Falle verschiedener Werkstoffkomponenten ist ein ebenso dichter Übergangsbereich erforderlich. A barrier layer 6, which is suitable for protecting the adhesive layer 4, is applied to this adhesive layer 4 using the same method. Metals, metal alloys, semiconductors, metal oxides, various carbides, for example WC, nitrides, cermets, sulfides, selenides, tellurides etc., have proven themselves as layer materials in accordance with their special properties. It is important that the surface or upper layer of the barrier layer 6 facing away from the adhesive layer 4 is designed to be solderable, the barrier layer 6 being able to consist of one or more materials which on the one hand connect tightly to the adhesive layer 6 and on the other hand have a tight solder connection let to finish the panels. In the case of different material components, an equally dense transition area is required.

Diese als Schichten verwendeten Werkstoffe und die die Platten einfassenden Folien sowie die Lötwerkstoffe weisen die gleichen oder wenigstens annähernd die gleichen Ausdehnungseigenschaften wie das für die Wandelemente verwendete Material, beispielsweise Glas auf. These materials used as layers and the foils surrounding the plates and the soldering materials have the same or at least approximately the same expansion properties as the material used for the wall elements, for example glass.
