Abstract

The invention relates to a spacer for multiple-glazed insulating glazing, comprising a base element (5), which has two parallel contact surfaces (9, 11) for the glazing panels (1, 3), and an adhesive surface (19) which is turned away from the inner space of the glazing unit and connects the two contact surfaces. The base element (5) is made of fibreglass reinforced plastic. Said spacer is characterized in that a metal foil (21) is glued against all of the adhesive surface (19), and in that by selecting the proportion of fibreglass in the plastic matter of the base element it is possible to match the coefficients of thermal expansion of the base element and the metal foil. This type of spacer ensures especially good leak tightness and lasting bonding between the plastic spacer and the metal foil, and between said metal foil and the sealant between the glazing panels.

Description

Die Erfindung betrifft einen Abstandhalter für Mehrscheiben-Isolierverglasung gemäss Oberbegriff des Anspruchs 1.The invention relates to a spacer for multi-pane insulating glazing according to the preamble of claim 1.

Solche Abstandhalter werden insbesondere bei Doppelscheiben-Isolierglas eingesetzt, um eine beabstandete Verbindung der beiden Einzelscheiben zu ermöglichen. Darüber hinaus sollen sie den zwischen den Scheiben entstandenen Innenraum nach aussen abdichten, so dass beispielsweise ein eingebrachtes Gas nicht entweichen kann. Im übrigen sollen sie durch entsprechende Ausgestaltung verhindern, dass Feuchtigkeit oder Luft von aussen in den Innenraum eindringen kann, was langfristig. zur Erblindung der Scheibe führt.Such spacers are used in particular in double-pane insulating glass to allow a spaced connection of the two individual panes. In addition, they should seal the resulting between the panes interior to the outside, so that, for example, a gas introduced can not escape. Moreover, they should prevent by appropriate design that moisture or air from the outside can penetrate into the interior, which in the long term. leads to blindness of the disc.

Vielen vorbekannten Abstandhaltern haftet jedoch der Nachteil an, dass sie im Gegensatz zu dem im Innenraum befindlichen Gas oder Luft eine höhere Wärmeleitfähigkeit aufweisen. Dadurch kühlt bei niedrigen Aussentemperaturen die innenliegende Scheibe im unmittelbaren Bereich um den Abstandhalter stark ab. Unerwünschte Feuchtigkeitsniederschläge an diesen Stellen sind die Folge.However, many previously known spacers have the disadvantage that, in contrast to the gas or air in the interior, they have a higher thermal conductivity. As a result, cools at low outside temperatures, the inner pane in the immediate area around the spacer from strong. Undesirable moisture precipitation at these points is the result.

Eine Verbesserung der Isoliereigenschaften von Abstandhaltern konnte man durch Verwendung eines Kunststoffmaterials erreichen. Hierbei ergibt sich jedoch das Problem, dass die zwischen den Kanten der beiden Scheiben eingebrachte Verklebungs- und Abdichtungsmasse, üblicherweise Polysulfid oder Silikon, sich schlecht mit dem Kunststoff verbindet, da diese Kleber üblicherweise speziell für Metall-Abstandhalter entwickelt wurden. Es ergibt sich daraus sowohl Undichtigkeiten zwischen Innenraum und aussen, als auch Hohlräume zwischen Abstandhalter und Abdichtungsmasse, in denen sich Feuchtigkeit sammeln kann und die Abdichtung weiter verschlechtert.An improvement in the insulating properties of spacers could be achieved by using a plastic material. Here, however, there is the problem that the introduced between the edges of the two discs bonding and sealing compound, usually polysulfide or silicone, badly connects to the plastic, since these adhesives were usually developed specifically for metal spacers. This results in both leaks between the interior and exterior, as well as cavities between spacers and sealing compound in which moisture can collect and the seal deteriorates further.

Ausserdem ist bekannt, die Festigkeit des Kunststoffes durch Verwendung von Glasfaser- oder Mineralpulververstärkung zu verbessern, z. B. gemäss EP-A-0 430 889 , US-A-5 260 112 oder EP-B-127 739 .It is also known to improve the strength of the plastic by using glass fiber or mineral powder reinforcement, for. B. according to EP-A-0 430 889 . US-A-5 260 112 or EP-B-127 739 ,

Gemäss letzterer Patentschrift, von der im Oberbegriff ausgegangen wird, ist die im eingebauten Zustand freie Fläche des Abstandhalters mit einer Metallschicht versehen, die als wasserdampfdiffusionshemmende Schicht dient. Diese Metallschicht wird mit dem Abstandhalter koextrudiert. Eine solche Beschichtungsart ergibt insbesondere bei grossen Temperaturschwankungen eine schlechte Haftung derr Metall-Folie. Dies ist dann vor allem wichtig, falls, im Unterschied zu dem Abstandhalter dieser Patentschrift, um den freien Teil des Abstandhalters, d.h. um die Metallschicht, eine Dichtmasse aufgebracht wird, die sowohl am Abstandhalter als auch an den Glasscheiben gut haften soll, um eine gesamthaft gesehen gute und dauerhafte Festigkeit zu erhalten.According to the latter patent, which is assumed in the preamble, the free in the installed state surface of the spacer is provided with a metal layer which serves as a water vapor diffusion-inhibiting layer. This metal layer is coextruded with the spacer. Such a type of coating gives poor adhesion of the metal foil, especially in the case of large temperature fluctuations. This is especially important if, unlike the spacer of this patent, the free part of the spacer, i. around the metal layer, a sealant is applied, which should adhere well to both the spacer and the glass sheets, in order to obtain an overall good and lasting strength.

Es ist von diesem Stand der Technik ausgehend Aufgabe der vorliegenden Erfindung, einen Abstandhalter vorzusehen, der, eine geringe Wärmeleitfähigkeit besitzend, eine sichere Verklebung und Abdichtung zulässt und bei dem insbesondere die Metallschicht gut am Kunststoffkörper haftet.It is from this prior art starting task of the present invention to provide a spacer which, having a low thermal conductivity, allows a secure bonding and sealing and in which in particular the metal layer adheres well to the plastic body.

Diese Aufgabe wird durch einen Abstandhalter entsprechend dem unabhängigen Anspruch 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den übrigen Ansprüchen zu entnehmen.This object is achieved by a spacer according to independent claim 1. Further advantageous embodiments can be found in the remaining claims.

Die Erfindung wird nun anhand eines Ausführungsbeispiels mit Bezug auf die einzige Figur, die im Querschnitt einen Kantenbereich einer Doppelverglasung zeigt, näher erläutert.The invention will now be explained in more detail using an exemplary embodiment with reference to the single figure, which shows an edge region of a double glazing in cross section.

Zwei nur auschnittsweise gezeigte Glasscheiben 1, 3 sind parallel zueinander mittels eines Abstandhalters 5 in einem Abstand zueinander angeordnet. Dieser Abstandhalter 5 erstreckt sich entlang der nicht gezeigten Kanten der beiden Glasscheiben 1, 3, so dass ein Glasscheiben-Innenraum 7 gebildet wird. Dieser Innenraum 7 ist üblicherweise mit Luft und vorzugsweise mit Gas gefüllt.Two glass panels 1, 3 only shown in detail are arranged parallel to each other by means of a spacer 5 at a distance from one another. This spacer 5 extends along the edges, not shown, of the two glass panes 1, 3, so that a glass pane interior 7 is formed. This interior 7 is usually filled with air and preferably with gas.

Der Abstandhalter 5 weist Anlageflächen 9 und 11 auf, die jeweils einer der beiden Scheiben 1, 3 zugewandt sind. Zur Abdichtung des Innenraums 7 weisen die Anlageflächen 9, 11 nutenförmige Ausnehmungen 13 und 15 auf, in die eine plastische Abdichtungsmasse, beispielsweise eine Butyl-Verbindung, insbesondere Butyl-Kautschuk (im folgenden kurz als Butyl bezeichnet), eingebracht ist. Die Ausnehmungen 13, 15 gewährleisten dabei immer eine Mindestanlagefläche und Mindestdicke des Butyls an den Glasscheiben.The spacer 5 has contact surfaces 9 and 11, which each face one of the two disks 1, 3. To seal the interior 7, the contact surfaces 9, 11 groove-shaped recesses 13 and 15, in which a plastic sealing compound, such as a butyl compound, in particular butyl rubber (hereinafter referred to as butyl) introduced. The recesses 13, 15 always ensure a minimum contact surface and minimum thickness of butyl on the glass panes.

Von der Anlagefläche 9 zur Aussenfläche 11 erstreckt sich eine der Aussenseite zugewandte, freie Fläche 19 (im folgenden als Verklebungsfläche bezeichnet). Diese Verklebungsfläche 19 weist einen im wesentlichen U-förmigen Querschnitt auf, wobei - im Querschnitt gesehen - die beiden Schenkel sich von den Anlageflächen 9 aus nach aussen verjüngen.From the contact surface 9 to the outer surface 11, an outer surface facing, free surface 19 extends (hereinafter referred to as bonding surface). This bonding surface 19 has a substantially U-shaped cross section, wherein - seen in cross section - the two legs taper from the contact surfaces 9 outwardly.

Auf dieser Verklebungsfläche 19 ist eine dünne Metall-Folie 21, insbesondere eine Aluminium-Folie, aufgebracht. Die Verbindung wird mit einem nicht-gasenden Klebemittels 23, beispielsweise einem PUR-Hotmelt-Kleber gewährleistet, der unter Feuchtigkeit aushärtet. Bei Verwendung eines üblichen Klebers diffundieren Gase durch den Abstandhalter hindurch in den Innenraum 7 und können dort zu einem chemischen Niederschlag an der Scheibe führen.On this bonding surface 19, a thin metal foil 21, in particular an aluminum foil applied. The compound is ensured with a non-gaseous adhesive 23, for example a PUR hotmelt adhesive, which cures under moisture. When using a conventional adhesive, gases diffuse through the spacer into the interior 7 and can lead to a chemical precipitation on the disc.

Um eine gute und dauerhafte Verbindung der Metall-Folie mit dem Kunststoffkörper zu gewährleisten, muss der Unterschied in der Wärmeausdehnung beider Teile möglichst klein sein, sonst besteht die Gefahr eines Abplatzens der Folie. Um einen möglichst guten Abgleich beider Wärmeausdehnungskoeffizienten zu erzielen, werden dem Kunststoff Glasfasern in einem geeignete Anteil zugemischt. Dabei ist es selbstverständlich, dass je nach Art der Folie, z.B. Aluminium oder Stahl, ein kleinerer oder grösserer Anteil kurzer Glasfasern, vorzugsweise bereits im Kunststoffgranulat, zugemischt wird. Ausserdem richtet sich die Beimengung auch nach der Art des Kunststoffes.In order to ensure a good and permanent connection of the metal foil with the plastic body, the difference in the thermal expansion of the two parts must be as small as possible, otherwise there is a risk of chipping the film. In order to achieve the best possible balance of the two coefficients of thermal expansion, the plastic glass fibers are mixed in a suitable proportion. That's it Of course, depending on the type of film, for example aluminum or steel, a smaller or larger proportion of short glass fibers, preferably already in the plastic granules, is admixed. In addition, the admixture also depends on the type of plastic.

Um eine gute Verarbeitung zu ermöglichen, wird die Verwendung von thermoplastischen Kunststoffen bevorzugt, beispielsweise ein unter dem Handelsnamen LURAN von BASF vertriebener SAN-Kunststoff mit Glasfasern. Bei der Verwendung eines solchen Kunststoffes und einer Aluminiumfolie, liegt der Glasfaseranteil beispielsweise bei ungefähr 35%.In order to enable a good processing, the use of thermoplastics is preferred, for example a SAN plastic with glass fibers marketed under the trade name LURAN by BASF. For example, when using such a plastic and an aluminum foil, the glass fiber content is about 35%.

In den zwischen den beiden Glasscheiben 1 und 3 und der Verklebungsfläche 19 ausgebildeten Raum 25 wird eine Klebebeziehungsweise Abdichtungsmasse 27, vorzugsweise Polysulfid oder Silikon, eingebracht, um einerseits die beiden Glasscheiben mit dem Abstandhalter zu verkleben und andererseits eine weitere Versiegelung des Innenraums 7 zu erwirken.In the formed between the two glass panes 1 and 3 and the bonding surface 19 space 25 is a Klebebeziehungsweise sealant 27, preferably polysulfide or silicone, introduced to one hand to glue the two glass panes with the spacer and on the other hand to obtain a further seal of the interior 7.

Da die Verklebungsfläche 19 nach aussen vollständig von der Metall-Folie 21 abgedeckt ist, kommt diese Abdichtungsmasse 27 nicht direkt mit dem Kunststoff des Abstandhalters in Kontakt, sondern mit dem Metall. Da die Haftung von Polysulfid oder Silikon an Metall deutlich höher als an Kunststoff ist, erreicht man auch eine bessere Verklebung der einzelnen Teile. Im übrigen löst sich die Abdichtungsmasse 27 nicht mehr von der Folie 21, so dass die Entstehung von Hohlräumen unterbunden werden kann.Since the bonding surface 19 is completely covered to the outside by the metal foil 21, this sealing compound 27 does not come into direct contact with the plastic of the spacer, but with the metal. Since the adhesion of polysulfide or silicone to metal is significantly higher than to plastic, one also achieves a better bonding of the individual parts. Moreover, the sealing compound 27 does not detach from the film 21, so that the formation of cavities can be prevented.

Aus der Figur ist des weiteren ersichtlich, dass der Abstandhalter 5 einen Hohlraum aufweist, der im Querschnitt gesehen von den beiden Anlageflächen 9, 11, der Verklebungsfläche 19 und einer dem Innenraum 7 zugewandten Wandung 31 umschlossen wird. Dadurch wird die durch die Glasfasern erzielte gute Stabilität des Halters weiter erhöht. Vorzugsweise ist in diesem Hohlraum 29 ein Trocknungsmittel 33, z.B. Silica-Gel, Molekularsiebe oder Mischungen der beiden Mittel eingesetzt, um Feuchtigkeit/Wasserdampf aus dem Innenraum 7 heraus zu ziehen. Um eine Verbindung zwischen dem Innenraum 7 und dem Hohlraum 29 herzustellen, sind in der Wandung 31 Durchbrüche 35 vorgesehen.It can further be seen from the figure that the spacer 5 has a cavity, which, viewed in cross-section, is enclosed by the two contact surfaces 9, 11, the bonding surface 19 and a wall 31 facing the inner space 7. As a result, the good stability of the holder achieved by the glass fibers is further increased. Preferably, in this cavity 29, a desiccant 33, e.g. Silica gel, molecular sieves or mixtures of the two agents used to pull moisture / water vapor out of the interior 7 out. In order to establish a connection between the interior 7 and the cavity 29, apertures 35 are provided in the wall 31.

In der Figur ist nicht eingezeichnet, dass die Abstandhalter 5 in Längsrichtung an den Ecken der Glasscheiben in einem Winkel von 90° gebogen sind. Dies ist möglich, da der Grundkörper aus einem thermoplastischen Kunststoff besteht. Dadurch kann wahlweise eine Eckverbindung verwendet oder eine Ecke gebogen werden.In the figure is not shown that the spacers 5 are bent in the longitudinal direction at the corners of the glass sheets at an angle of 90 °. This is possible because the base body consists of a thermoplastic material. As a result, either a corner joint can be used or a corner can be bent.

Die Figur lässt noch erkennen, dass die Längskanten der Metall-Folie 21 nicht mit den benachbarten Glasscheiben 1 beziehungsweise 3 in Kontakt kommen. Damit ist gewährleistet, dass zwischen der Scheibe und der gut wärmeleitenden Folie 21 ein mit der Abdichtungsmasse 27 gefüllter isolierender Spalt ausgebildet wird. Zusätzlich wird die Wärme- beziehungsweise Kälte-Übertragung der Metall-Folie dadurch verringert, dass bei der Metall-Folie eine Dicke unter 0.1 mm verwendet wird und der Weg zwischen den beiden Glasscheiben 1,3 durch die U-, bzw. V-förmige Ausgestaltung der Verklebungsfläche 19 vergrössert wird. Es sind auch andere Formen des Kunststoffprofils denkbar.The figure can still be seen that the longitudinal edges of the metal foil 21 do not come into contact with the adjacent glass panes 1 and 3 respectively. This ensures that an insulating gap 27 filled with the sealing compound 27 is formed between the pane and the good heat-conducting film 21. In addition, the heat or cold transfer of the metal foil is reduced by using a thickness of less than 0.1 mm for the metal foil and the path between the two glass panes 1, 3 through the U-shaped or V-shaped configuration the bonding surface 19 is increased. There are also other forms of plastic profile conceivable.
