Definitions

  • the invention relates to a glazing with a spacer comprising a plastic profile, a method for their preparation and their use.
  • Insulating glazings consisting of two or more panes.
  • Insulating glazings are made of at least two panes, which are connected to each other via at least one circumferential spacer.
  • interior space between the two panes is air or gas filled, but in any case free of moisture. Too high a content of moisture in the interior of the glazing leads to the condensation of water droplets in the interior of the glazing, especially in cold outside temperatures, which must be avoided at all costs.
  • spacers containing a desiccant may be used to hold the residual moisture remaining in the system after installation.
  • the absorption capacity of the desiccant is limited, in this case, the sealing of the system is of enormous importance to prevent the ingress of further moisture.
  • sealant prevent gas and moisture exchange between the space between the panes and the environment and contribute to the mechanical stability of the insulating glass element.
  • Spacers made of different materials are known. Spacers made of high thermal conductivity materials such as aluminum have the disadvantage that at low outside temperatures they cause the disc edge to cool down considerably, which may degrade the thermal insulation and lead to the formation of condensation on the inside of the pane.
  • Spacers made of lower thermal conductivity materials are therefore preferred (so-called "warm-edge” systems). Spacers made of polymeric materials have these improved heat-insulating properties.
  • spacers of dimensionally stable plastics which, in cavities or recesses, comprise desiccant or desiccant-filled matrix contain. Often these spacers consisting of several components must be assembled in several individual stages of the process, which makes the production expensive. A starting point for minimizing the production steps is to co-extrude the individual components.
  • Insulating glazing containing more than two panes are usually separated by several individual spacers.
  • a further pane is placed on a double glazing by means of an additional spacer.
  • thermoplastic materials for the production of spacers is known, which are either produced as a prefabricated profile and then fixed between the disks, or are extruded directly onto the disk.
  • the disc contact surfaces of the spacer must be provided with an adhesive in a separate production step.
  • the material properties must be precisely matched to prevent detachment of the spacer from the disc.
  • Sprayable thermoplastic spacers made of sealing materials such as polyisobutylene and butyl rubber which contain desiccants in the matrix, so that a step for filling hollow bodies in dimensionally stable spacers is eliminated.
  • they can be injected simultaneously on two sides of a central pane of the same height, so that the strict specifications for the installation of triple-glazing are met.
  • These sprayable thermoplastic spacers are dark colored, have a rough surface and are therefore visually unappealing and their labeling for the purpose of disk marking is difficult.
  • inaccuracies may occur during production of the sprayable spacers which lead to unevennesses on the wafer contact surface.
  • DE 696 07 473 discloses a double glazing with a composite spacer of an insulating foam body, sealing material and desiccant matrix, which can advantageously co-extruded simultaneously.
  • the problem arises of positioning all the spacers between the individual panes at exactly the same height.
  • the assembly of the triple glazing would have to be done gradually.
  • DE 25 55 384 C3 discloses an intermediate layer of a plastic material with incorporated desiccant, wherein the intermediate layer contains desiccant over the entire cross section.
  • the intermediate layer thus serves as a spacer and sealant.
  • the desiccant contained reduces the adhesive effect of the sealant, which may cause the layer to peel off over time and migrate to the visible area of the interpane space (so-called garland effect).
  • EP 2 420 536 A1 discloses a sealant consisting of a primary sealant containing a butyl sealant and a secondary sealant, wherein the primary sealant contains a polymer modified with specific reactive groups and the secondary sealant is a silicone-based sealant.
  • This spacer is like the described sprayable spacers dark colored and therefore visually less appealing.
  • the object of the present invention is to provide an insulating glazing, which does not have the disadvantages mentioned and which is economical and inexpensive to produce.
  • the insulating glazing comprises at least a first disc, a second disc, a third disc arranged between the first disc and the second disc, an inner space between the panes, an outer space between the panes and a spacer.
  • the spacer comprises at least a first glazing interior surface, a second glazing interior surface interior surface, a first disc contact surface and a second disc contact surface, at least one plastic profile, a primary sealant and a base body containing at least one sealing material comprising a dry material.
  • the plastic profile is disposed on the glazing interior surface and separates the outer pane space from the inner pane space and defines the distance between the adjacent panes.
  • the plastic profile contains a groove for receiving a third disc.
  • the groove extends parallel to the first disc contact surface and the second disc contact surface and can protrude into the main body.
  • the groove may have different geometries, for example, it may be rectangular or trapezoidal shaped.
  • the third disc is inserted into the groove and is fixed so that no gluing of the disc is required.
  • An advantage of the one-piece design of the plastic profile is that the glazing interior surfaces are automatically level with each other without the need for special assembly precautions.
  • the plastic profile can be designed visually appealing and labeled for example for the purpose of product identification.
  • the base body of sealing material with desiccant is disposed in the outer space between the panes adjacent to the plastic profile. The sealing material has good adhesive and adhesive properties on glass.
  • an insulating glazing is provided by the invention, which can be made visually appealing by the plastic profile and in which the migration of the arranged between the outer discs sealing material in the glazing interior (garland effect) is prevented by the plastic profile.
  • the first disc contact surface and the second disc contact surface represent the sides of the spacer at which the mounting of the outer discs (first disc and second disc) of an insulating glazing takes place during installation of the spacer.
  • the first disc contact surface and the second disc contact surface are parallel to each other.
  • the glazing interior surfaces are defined as the surfaces of the polymeric base body, which point after installation of the spacer in an insulating glazing in the direction of the interior of the glazing.
  • the first glazing interior space lies between the first and the third pane, while the second glazing interior space is arranged between the third and the second pane.
  • the groove is wider than the disc mounted therein, so that in addition an insert can be inserted into the groove, which prevents slipping of the disc and a consequent noise during opening and closing of the window.
  • the insert also compensates for the thermal expansion of the third disc when heated, so that regardless of the climatic conditions, a tension-free fixation is guaranteed.
  • the use of a liner is advantageous in terms of minimizing the variety of variants of the plastic profile.
  • a plastic profile can be used with various deposits.
  • the insert can also be formed directly on the polymeric body, for example, by both components are manufactured together in a two-component injection molding process.
  • the insert preferably contains an elastomer, particularly preferably ethylene-propylene-diene rubber and / or a thermoplastic polyurethane. Very good results are achieved with these materials.
  • the insert preferably contains a silicone and / or a polysulfide. These materials are particularly easy to process and can be injected into the groove.
  • the primary sealing means in the outer space between the panes is arranged adjacent to the base body and to the disk contact surfaces.
  • the base body is surrounded on three sides by primary sealant and limited to the inner pane clearance by the plastic profile.
  • the primary sealant has better adhesive properties than the base material, which in addition to sealing material also contains desiccant.
  • the arrangement of the primary sealant in addition to the disc contact surfaces, the tightness and stability of the arrangement are improved.
  • the main body and the primary sealant are made in one piece, preferably co-extruded. The co-extrusion creates a particularly strong bond between the individual components without the use of additional adhesives.
  • the plastic profile at the glazing interior surfaces at least one opening, preferably a plurality of openings, which allow the gas and moisture exchange between the base body and the glazing interior. This allows the absorption of moisture by the desiccant contained in the body.
  • a secondary sealing means is introduced in the outer pane cavity adjacent to the primary sealing means, which fills the space between the disc in its entire width between the first disc and the second disc.
  • This secondary sealant causes a bonding of the first and the second disc and thus ensures sufficient mechanical stability of the insulating glazing.
  • the secondary sealant preferably contains polysulfides, silicones, silicone rubber, polyurethanes, polyacrylates, copolymers and / or mixtures thereof. Such materials have a very good adhesion to glass, so that the secondary sealant is mainly used for bonding the discs and contributes to the mechanical stability of the insulating glazing.
  • the main body contains a sealing material, preferably butyl rubber, polyisobutylene, or a hot-melt adhesive and includes a desiccant, which preferably contains silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof ,
  • a sealing material preferably butyl rubber, polyisobutylene, or a hot-melt adhesive
  • a desiccant which preferably contains silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof ,

Description

ISOLIERVERGLASUNG MIT ABSTANDHALTER UND VERFAHREN ZUR  INSULATION GLAZING WITH SPACERS AND METHOD FOR
HERSTELLUNG  MANUFACTURING
Die Erfindung betrifft eine Isolierverglasung mit einem Abstandhalter umfassend ein Kunststoffprofil, ein Verfahren zu deren Herstellung und deren Verwendung. The invention relates to a glazing with a spacer comprising a plastic profile, a method for their preparation and their use.
Der Aufbau von Isolierverglasungen bestehend aus zwei oder mehr Scheiben ist bekannt. Isolierverglasungen werden aus mindestens zwei Scheiben gefertigt, die über mindestens einen umlaufenden Abstandhalter miteinander verbunden sind. Je nach Ausführungsform ist der als Verglasungsinnenraum bezeichnete Zwischenraum der beiden Scheiben luft- oder gasgefüllt, in jedem Fall jedoch frei von Feuchtigkeit. Ein zu hoher Gehalt an Feuchtigkeit im Verglasungsinnenraum führt besonders bei kalten Außentemperaturen zur Kondensation von Wassertropfen im Verglasungsinnenraum, was unbedingt zu vermeiden ist. Zur Aufnahme der nach der Montage im System verbleibenden Restfeuchtigkeit können beispielsweise Abstandhalter, die ein Trockenmittel enthalten, verwendet werden. Da die Aufnahmekapazität des Trockenmittels jedoch begrenzt ist, ist auch in diesem Fall die Abdichtung des Systems von enormer Wichtigkeit um das Eindringen weiterer Feuchtigkeit zu vermeiden. Bei gasgefüllten Isolierverglasungen, in deren Verglasungsinnenraum beispielsweise eine Argonfüllung eingebracht ist, muss des Weiteren auch eine Dichtigkeit gegenüber Gasen gewährleistet sein. Ein oder mehrere Schichten Dichtmittel und im Bedarfsfall Folie verhindern den Gas- und Feuchtigkeitsaustausch zwischen Scheibenzwischenraum und der Umwelt sowie tragen zur mechanischen Stabilität des Isolierglaselements bei. The construction of insulating glazings consisting of two or more panes is known. Insulating glazings are made of at least two panes, which are connected to each other via at least one circumferential spacer. Depending on the embodiment of the designated as glazing interior space between the two panes is air or gas filled, but in any case free of moisture. Too high a content of moisture in the interior of the glazing leads to the condensation of water droplets in the interior of the glazing, especially in cold outside temperatures, which must be avoided at all costs. For example, spacers containing a desiccant may be used to hold the residual moisture remaining in the system after installation. However, since the absorption capacity of the desiccant is limited, in this case, the sealing of the system is of enormous importance to prevent the ingress of further moisture. In the case of gas-filled insulating glazings in whose glazing interior, for example, an argon filling is introduced, sealing against gases must also be ensured. One or more layers of sealant and, if necessary, foil prevent gas and moisture exchange between the space between the panes and the environment and contribute to the mechanical stability of the insulating glass element.
Abstandhalter aus verschiedenen Materialien sind bekannt. Abstandhalter aus Materialien mit hoher Wärmeleitfähigkeit wie zum Beispiel Aluminium haben den Nachteil, dass sie bei niedrigen Außentemperaturen zu einem starken Abkühlen des Scheibenrands führen, was die Wärmedämmung verschlechtert und zur Bildung von Kondenswasser auf der Scheibe an der Gebäudeinnenseite führen kann. Spacers made of different materials are known. Spacers made of high thermal conductivity materials such as aluminum have the disadvantage that at low outside temperatures they cause the disc edge to cool down considerably, which may degrade the thermal insulation and lead to the formation of condensation on the inside of the pane.
Abstandhalter aus Materialien mit geringerer Wärmeleitfähigkeit werden daher bevorzugt (sogenannte ,,Warme-Kante"-Systeme). Abstandhalter aus polymeren Materialien haben diese verbesserten Wärme-dämmenden Eigenschaften. Spacers made of lower thermal conductivity materials are therefore preferred (so-called "warm-edge" systems). Spacers made of polymeric materials have these improved heat-insulating properties.
Es sind zum Beispiel Abstandhalter aus formstabilen Kunststoffen bekannt, die in Hohlräumen oder Aussparungen Trockenmittel oder mit Trockenmittel gefüllte Matrix enthalten. Oft müssen diese aus mehreren Komponenten bestehenden Abstandhalter in mehreren einzelnen Prozessstufen zusammengebaut werden, was die Produktion aufwendig gestaltet. Ein Ansatzpunkt zur Minimierung der Produktionsschritte ist die einzelnen Bestandteile zu co-extrudieren. For example, spacers of dimensionally stable plastics are known which, in cavities or recesses, comprise desiccant or desiccant-filled matrix contain. Often these spacers consisting of several components must be assembled in several individual stages of the process, which makes the production expensive. A starting point for minimizing the production steps is to co-extrude the individual components.
Isolierverglasungen, die mehr als zwei Scheiben enthalten, sind meist über mehrere einzelne Abstandhalter voneinander getrennt. Für eine Dreifachverglasung wird dabei auf eine Doppelverglasung mittels eines zusätzlichen Abstandhalters eine weitere Scheibe aufgesetzt. Bei der Montage einer solchen Mehrfachverglasung gelten sehr geringe Toleranzvorgaben, da alle Abstandhalter in genau gleicher Höhe angebracht werden müssen. Daher ist die Montage von Mehrfachverglasungen mit mehr als zwei Scheiben im Vergleich zu Doppelverglasungen aufwändiger, da entweder zusätzliche Anlagenkomponenten für die Montage einer weiteren Scheibe benötigt werden oder ein zeitaufwändiger Mehrfachdurchlauf einer klassischen Anlage notwendig ist. Insulating glazing containing more than two panes are usually separated by several individual spacers. For a triple glazing, a further pane is placed on a double glazing by means of an additional spacer. When installing such a multiple glazing apply very low tolerance requirements, since all spacers must be mounted in exactly the same height. Therefore, the installation of multiple glazing with more than two panes compared to double glazing complex, since either additional system components for the installation of another disc are required or a time-consuming multiple pass of a classic system is necessary.
Die Verwendung thermoplastischer Materialien zur Herstellung von Abstandhaltern ist bekannt, die entweder als vorgefertigtes Profil hergestellt und anschließend zwischen den Scheiben fixiert werden, oder direkt auf die Scheibe extrudiert werden. Im ersten Fall müssen in einem separaten Produktionsschritt die Scheibenkontaktflächen des Abstandhalters mit einem Klebemittel versehen werden. Die Materialeigenschaften müssen genau aufeinander abgestimmt sein, um ein Ablösen des Abstandhalters von der Scheibe zu verhindern. The use of thermoplastic materials for the production of spacers is known, which are either produced as a prefabricated profile and then fixed between the disks, or are extruded directly onto the disk. In the first case, the disc contact surfaces of the spacer must be provided with an adhesive in a separate production step. The material properties must be precisely matched to prevent detachment of the spacer from the disc.
Spritzbare thermoplastische Abstandhalter aus Dichtmaterialien wie Polyisobutylen und Butylkautschuk sind bekannt, die in der Matrix Trockenmittel enthalten, sodass ein Schritt zum Befüllen von Hohlkörpern in formstabilen Abstandhaltern entfällt. Zur Herstellung von Isolierverglasungen mit mehr als zwei Scheiben können diese gleichzeitig auf zwei Seiten einer mittleren Scheibe in gleicher Höhe eingespritzt werden, sodass die strengen Vorgaben bei der Montage von Dreifachisolier- verglasungen erfüllt werden. Diese spritzbaren thermoplastischen Abstandhalter sind dunkel gefärbt, haben eine raue Oberfläche und sind daher optisch wenig ansprechend und deren Beschriftung zum Zweck der Scheibenkennzeichnung ist schwierig. Bei der Herstellung der spritzbaren Abstandhalter können zudem Ungenauigkeiten auftreten, die zu Unebenheiten an der Scheibenkontaktfläche führen. Diese Unebenheiten führen in der Isolierverglasung zu Spannungen und schließlich zu einem Versagen der dichten Verbindung zwischen Scheibe und Abstandhalter. DE 696 07 473 offenbart eine Doppelverglasung mit einem zusammengesetzten Abstandhalter aus einem isolierenden Schaumstoffkörper, Abdichtungsmaterial und Trockenmittelmatrix, die vorteilhaft gleichzeitig co-extrudiert werden können. Bei der Anwendung auf eine Dreifachverglasung stellt sich das Problem, alle Abstandhalter zwischen den einzelnen Scheiben auf exakt gleicher Höhe zu positionieren. Zudem müsste der Zusammenbau der Dreifachverglasung stufenweise erfolgen. Sprayable thermoplastic spacers made of sealing materials such as polyisobutylene and butyl rubber are known, which contain desiccants in the matrix, so that a step for filling hollow bodies in dimensionally stable spacers is eliminated. In order to produce insulating glazing with more than two panes, they can be injected simultaneously on two sides of a central pane of the same height, so that the strict specifications for the installation of triple-glazing are met. These sprayable thermoplastic spacers are dark colored, have a rough surface and are therefore visually unappealing and their labeling for the purpose of disk marking is difficult. In addition, inaccuracies may occur during production of the sprayable spacers which lead to unevennesses on the wafer contact surface. These bumps lead in the insulating glazing to tensions and finally to a failure of the tight connection between the disc and spacer. DE 696 07 473 discloses a double glazing with a composite spacer of an insulating foam body, sealing material and desiccant matrix, which can advantageously co-extruded simultaneously. When applied to triple glazing, the problem arises of positioning all the spacers between the individual panes at exactly the same height. In addition, the assembly of the triple glazing would have to be done gradually.
DE 25 55 384 C3 offenbart eine Zwischenschicht aus einem Kunststoffmaterial mit eingearbeitetem Trockenmittel, wobei die Zwischenschicht über den gesamten Querschnitt Trockenmittel enthält. Die Zwischenschicht dient demnach als Abstandhalter und Dichtmittel. Das enthaltene Trockenmittel verringert die Klebewirkung des Dichtmittels, was dazu führen kann, dass die Schicht sich im Laufe der Zeit ablöst und in den sichtbaren Bereich des Scheibenzwischenraums wandert (sogenannter Girlandeneffekt). DE 25 55 384 C3 discloses an intermediate layer of a plastic material with incorporated desiccant, wherein the intermediate layer contains desiccant over the entire cross section. The intermediate layer thus serves as a spacer and sealant. The desiccant contained reduces the adhesive effect of the sealant, which may cause the layer to peel off over time and migrate to the visible area of the interpane space (so-called garland effect).
EP 2 420 536 A1 offenbart eine Dichtmasse bestehend aus einem Primärdichtstoff enthaltend einen Butyldichtstoff und einem Sekundärdichtstoff, wobei der Primärdichtstoff ein mit speziellen reaktiven Gruppen modifiziertes Polymer enthält und der Sekundärdichtstoff ein Dichtstoff auf Silikonbasis ist. Dieser Abstandhalter ist wie die beschriebenen spritzbaren Abstandhalter dunkel gefärbt und daher optisch wenig ansprechend. EP 2 420 536 A1 discloses a sealant consisting of a primary sealant containing a butyl sealant and a secondary sealant, wherein the primary sealant contains a polymer modified with specific reactive groups and the secondary sealant is a silicone-based sealant. This spacer is like the described sprayable spacers dark colored and therefore visually less appealing.
Die Aufgabe der vorliegenden Erfindung ist es, eine Isolierverglasung bereitzustellen, die die genannten Nachteile nicht aufweist und die wirtschaftlich und kostengünstig herstellbar ist. The object of the present invention is to provide an insulating glazing, which does not have the disadvantages mentioned and which is economical and inexpensive to produce.
Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch eine Isolierverglasung nach dem unabhängigen Anspruch 1 gelöst. Bevorzugte Ausführungen der Erfindung gehen aus den Unteransprüchen hervor. The object of the present invention is achieved by an insulating glazing according to the independent claim 1. Preferred embodiments of the invention will become apparent from the dependent claims.
Die erfindungsgemäße Isolierverglasung umfasst mindestens eine erste Scheibe, eine zweite Scheibe, eine zwischen der ersten Scheibe und der zweiten Scheibe angeordnete dritte Scheibe, einen inneren Scheibenzwischenraum, einen äußeren Scheibenzwischenraum und einen Abstandhalter. Der Abstandhalter umfasst mindestens eine erste Verglasungsinnenraumfläche, eine zweite Verglasungs- innenraumfläche, eine erste Scheibenkontaktfläche und eine zweite Scheibenkontakt- fläche, mindestens ein Kunststoffprofil, ein primäres Dichtmittel und einen Grundkörper enthaltend mindestens ein Dichtmaterial beinhaltend ein Trockenmaterial. Das Kunststoffprofil ist an der Verglasungsinnenraumfläche angeordnet und trennt den äußeren Scheibenzwischenraum vom inneren Scheibenzwischenraum und definiert den Abstand zwischen den anliegenden Scheiben. Das Kunststoffprofil enthält eine Nut für die Aufnahme einer dritten Scheibe. Die Nut verläuft parallel zur ersten Scheibenkontaktfläche und zweiten Scheibenkontaktfläche und kann in den Grundkörper hineinragen. Die Nut kann verschiedene Geometrien aufweisen, zum Beispiel kann sie rechteckig oder trapezförmig ausgeformt sein. Die dritte Scheibe ist in die Nut eingesetzt und wird so fixiert ohne dass eine Verklebung der Scheibe erforderlich ist. Ein Vorteil der einteiligen Ausführung des Kunststoffprofils ist, dass die Verglasungsinnenraumflächen automatisch auf gleicher Höhe sind, ohne dass besondere Vorkehrungen beim Zusammenbau notwendig sind. Das Kunststoffprofil kann optisch ansprechend gestaltet und zum Beispiel zum Zweck der Produktkennzeichnung beschriftet werden. Der Grundkörper aus Dichtmaterial mit Trockenmittel ist im äußeren Scheibenzwischenraum angrenzend an das Kunststoffprofil angeordnet. Das Dichtmaterial hat gute Klebe- und Hafteigenschaften auf Glas. Der Grundkörper verklebt zum einen die Glasscheiben und fixiert das Kunststoffprofil dauerhaft in Position, und beinhaltet zum anderen das Trockenmittel zur Bindung eventuell vorhandener Feuchtigkeit im inneren Scheibenzwischenraum. Angrenzend an den Grundkörper ist im äußeren Scheibenzwischenraum das primäre Dichtmittel angeordnet, das den vom umlaufenden Abstandhalter und den Scheiben eingeschlossenen Verglasungsinnenraum gegen Gasaustausch und Eindringen von Feuchtigkeit versiegelt. The insulating glazing according to the invention comprises at least a first disc, a second disc, a third disc arranged between the first disc and the second disc, an inner space between the panes, an outer space between the panes and a spacer. The spacer comprises at least a first glazing interior surface, a second glazing interior surface interior surface, a first disc contact surface and a second disc contact surface, at least one plastic profile, a primary sealant and a base body containing at least one sealing material comprising a dry material. The plastic profile is disposed on the glazing interior surface and separates the outer pane space from the inner pane space and defines the distance between the adjacent panes. The plastic profile contains a groove for receiving a third disc. The groove extends parallel to the first disc contact surface and the second disc contact surface and can protrude into the main body. The groove may have different geometries, for example, it may be rectangular or trapezoidal shaped. The third disc is inserted into the groove and is fixed so that no gluing of the disc is required. An advantage of the one-piece design of the plastic profile is that the glazing interior surfaces are automatically level with each other without the need for special assembly precautions. The plastic profile can be designed visually appealing and labeled for example for the purpose of product identification. The base body of sealing material with desiccant is disposed in the outer space between the panes adjacent to the plastic profile. The sealing material has good adhesive and adhesive properties on glass. The main body glued to the glass panes and fixes the plastic profile permanently in position, and on the other hand includes the desiccant for binding any existing moisture in the inner space between the panes. Adjacent to the base body, the primary sealing means is arranged in the outer space between the panes, which seals the glazing interior enclosed by the circumferential spacer and the panes against gas exchange and the ingress of moisture.
Somit wird durch die Erfindung eine Isolierverglasung bereitgestellt, die durch das Kunststoffprofil optisch ansprechend gestaltet werden kann und bei der die Wanderung des zwischen den äußeren Scheiben angeordneten Dichtmaterials in den Verglasungsinnenraum (Girlandeneffekt) durch das Kunststoffprofil verhindert wird. Die erste Scheibenkontaktfläche und die zweite Scheibenkontaktfläche stellen die Seiten des Abstandhalters dar, an denen beim Einbau des Abstandhalters die Montage der äußeren Scheiben (erste Scheibe und zweite Scheibe) einer Isolierverglasung erfolgt. Die erste Scheibenkontaktfläche und die zweite Scheibenkontaktfläche verlaufen parallel zueinander. Die Verglasungsinnenraumflächen sind als die Flächen des polymeren Grundkörpers definiert, die nach Einbau des Abstandhalters in einer Isolierverglasung in Richtung des Innenraums der Verglasung weisen. Die erste Verglasungsinnenraumflache liegt dabei zwischen der ersten und der dritten Scheibe, während die zweite Verglasungsinnenraumflache zwischen der dritten und der zweiten Scheibe angeordnet ist. Thus, an insulating glazing is provided by the invention, which can be made visually appealing by the plastic profile and in which the migration of the arranged between the outer discs sealing material in the glazing interior (garland effect) is prevented by the plastic profile. The first disc contact surface and the second disc contact surface represent the sides of the spacer at which the mounting of the outer discs (first disc and second disc) of an insulating glazing takes place during installation of the spacer. The first disc contact surface and the second disc contact surface are parallel to each other. The glazing interior surfaces are defined as the surfaces of the polymeric base body, which point after installation of the spacer in an insulating glazing in the direction of the interior of the glazing. The first glazing interior space lies between the first and the third pane, while the second glazing interior space is arranged between the third and the second pane.
In einer bevorzugten Ausführungsform ist die Nut breiter als die darin montierte Scheibe, so dass zusätzlich eine Einlage in die Nut eingesetzt werden kann, die ein Verrutschen der Scheibe und eine dadurch bedingte Geräuschentwicklung beim Öffnen und Schließen des Fensters verhindert. Die Einlage kompensiert des Weiteren die thermische Ausdehnung der dritten Scheibe bei Erwärmung, so dass unabhängig von den klimatischen Bedingungen eine spannungsfreie Fixierung gewährleistet ist. Ferner ist die Verwendung einer Einlage vorteilhaft in Bezug auf die Minimierung der Variantenvielfalt des Kunststoffprofils. Um die Variantenvielfalt möglichst gering zu halten und trotzdem eine variable Dicke der mittleren Scheibe zu ermöglichen kann ein Kunststoffprofil mit verschiedenen Einlagen eingesetzt werden. Die Einlage kann auch direkt an den polymeren Grundkörper angeformt werden, beispielsweise indem beide Bauteile gemeinsam in einem Zweikomponentenspritzgussverfahren gefertigt werden. In a preferred embodiment, the groove is wider than the disc mounted therein, so that in addition an insert can be inserted into the groove, which prevents slipping of the disc and a consequent noise during opening and closing of the window. The insert also compensates for the thermal expansion of the third disc when heated, so that regardless of the climatic conditions, a tension-free fixation is guaranteed. Furthermore, the use of a liner is advantageous in terms of minimizing the variety of variants of the plastic profile. In order to keep the variety as low as possible and still allow a variable thickness of the middle disc, a plastic profile can be used with various deposits. The insert can also be formed directly on the polymeric body, for example, by both components are manufactured together in a two-component injection molding process.
Die Einlage enthält bevorzugt ein Elastomer, besonders bevorzugt Ethylen-Propylen- Dien-Kautschuk und/oder ein thermoplastisches Polyurethan. Mit diesen Materialien werden sehr gute Ergebnisse erzielt. The insert preferably contains an elastomer, particularly preferably ethylene-propylene-diene rubber and / or a thermoplastic polyurethane. Very good results are achieved with these materials.
Die Einlage enthält bevorzugt ein Silikon und / oder ein Polysulfid. Diese Materialien lassen sich besonders leicht verarbeiten und können in die Nut eingespritzt werden. The insert preferably contains a silicone and / or a polysulfide. These materials are particularly easy to process and can be injected into the groove.
In einer bevorzugten Ausführungsform ist das primäre Dichtmittel im äußeren Scheibenzwischenraum angrenzend an den Grundkörper und an den Scheiben- kontaktflächen angeordnet. In dieser Anordnung ist der Grundkörper an drei Seiten von primärem Dichtmittel umgeben und zum inneren Scheibenzwischenraum durch das Kunststoffprofil begrenzt. Das primäre Dichtmittel hat bessere Hafteigenschaften als das Material des Grundkörpers, das zusätzlich zu Dichtmaterial auch Trockenmittel enthält. Durch die Anordnung des primären Dichtmittels zusätzlich an den Scheiben- kontaktflächen werden die Dichtigkeit und Stabilität der Anordnung verbessert. In einer bevorzugten Ausführungsform sind der Grundkörper und das primäre Dichtmittel einteilig ausgeführt, bevorzugt co-extrudiert. Durch die Co-Extrusion entsteht ein besonders fester Verbund zwischen den einzelnen Bestandteilen ohne den Einsatz zusätzlicher Haftmittel. In a preferred embodiment, the primary sealing means in the outer space between the panes is arranged adjacent to the base body and to the disk contact surfaces. In this arrangement, the base body is surrounded on three sides by primary sealant and limited to the inner pane clearance by the plastic profile. The primary sealant has better adhesive properties than the base material, which in addition to sealing material also contains desiccant. The arrangement of the primary sealant in addition to the disc contact surfaces, the tightness and stability of the arrangement are improved. In a preferred embodiment, the main body and the primary sealant are made in one piece, preferably co-extruded. The co-extrusion creates a particularly strong bond between the individual components without the use of additional adhesives.
In einer bevorzugten Ausführung enthält das Kunststoffprofil an den Verglasungs- innenraumflächen mindestens eine Öffnung, bevorzugt mehrere Öffnungen, die den Gas- und Feuchtigkeitsaustausch zwischen dem Grundkörper und dem Verglasungs- innenraum ermöglichen. Dadurch wird die Aufnahme von Feuchtigkeit durch das Trockenmittel, das in dem Grundkörper enthalten ist, erlaubt. In a preferred embodiment, the plastic profile at the glazing interior surfaces at least one opening, preferably a plurality of openings, which allow the gas and moisture exchange between the base body and the glazing interior. This allows the absorption of moisture by the desiccant contained in the body.
In einer bevorzugten Ausführungsform ist im äußeren Scheibenzwischenraum angrenzend an das primäre Dichtmittel ein sekundäres Dichtmittel eingebracht, das den Scheibenzwischenraum in seiner gesamten Breite zwischen der ersten Scheibe und der zweiten Scheibe ausfüllt. Dieses sekundäre Dichtmittel bewirkt eine Verklebung der ersten und der zweiten Scheibe und gewährleistet somit eine ausreichende mechanische Stabilität der Isolierverglasung. Das sekundäre Dichtmittel enthält bevorzugt Polysulfide, Silikone, Silikonkautschuk, Polyurethane, Polyacrylate, Copolymere und/oder Gemische davon. Derartige Stoffe haben eine sehr gute Haftung auf Glas, so dass das sekundäre Dichtmittel vor allem der Verklebung der Scheiben dient und zur mechanischen Stabilität der Isolierverglasung beiträgt. In a preferred embodiment, a secondary sealing means is introduced in the outer pane cavity adjacent to the primary sealing means, which fills the space between the disc in its entire width between the first disc and the second disc. This secondary sealant causes a bonding of the first and the second disc and thus ensures sufficient mechanical stability of the insulating glazing. The secondary sealant preferably contains polysulfides, silicones, silicone rubber, polyurethanes, polyacrylates, copolymers and / or mixtures thereof. Such materials have a very good adhesion to glass, so that the secondary sealant is mainly used for bonding the discs and contributes to the mechanical stability of the insulating glazing.
Der Grundkörper enthält ein Dichtmaterial, bevorzugt Butylkautschuk, Polyisobutylen, oder einen Hot-Melt-Klebstoff und beinhaltet ein Trockenmittel, das bevorzugt Kieselgele, Molekularsiebe, CaCI2, Na2S04, Aktivkohle, Silikate, Bentonite, Zeolithe und/oder Gemische davon enthält. The main body contains a sealing material, preferably butyl rubber, polyisobutylene, or a hot-melt adhesive and includes a desiccant, which preferably contains silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and / or mixtures thereof ,
Das primäre Dichtmittel und der Grundkörper enthalten bevorzugt dasselbe Dichtmaterial, wobei der Grundkörper zusätzlich Trockenmittel enthält. Dadurch werden Materialunverträglichkeiten an der Grenzfläche zwischen primärem Dichtmittel und Grundkörper vermieden. The primary sealant and the base body preferably contain the same sealing material, wherein the base body additionally contains desiccant. As a result, material incompatibilities are avoided at the interface between primary sealant and body.
Das Kunststoffprofil enthält bevorzugt Polyethylen (PE), Polycarbonate (PC), Polypropylen (PP), Polystyrol, Polybutadien, Polynitrile, Polyester, Polyurethane, Polymethylmetacrylate, Polyacrylate, Polyamide, Polyethylenterephthalat (PET), Polybutylenterephthalat (PBT), Acrylnitril-Butadien-Styrol (ABS), Acrylester-Styrol- Acrylnitril (ASA), Acrylnitril-Butadien-Styrol / Polycarbonat (ABS/PC), Styrol-Acrylnitril (SAN), PET/PC, PBT/PC und/oder Copolymere oder Gemische davon. Das Kunststoffprofil kann optional auch weitere Bestandteile, wie beispielsweise Glasfasern, enthalten. The plastic profile preferably contains polyethylene (PE), polycarbonates (PC), polypropylene (PP), polystyrene, polybutadiene, polynitriles, polyesters, polyurethanes, polymethylmethacrylates, polyacrylates, polyamides, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile-butadiene-styrene (ABS), acrylic ester styrene Acrylonitrile (ASA), acrylonitrile-butadiene-styrene / polycarbonate (ABS / PC), styrene-acrylonitrile (SAN), PET / PC, PBT / PC and / or copolymers or blends thereof. The plastic profile may optionally also contain other constituents, such as glass fibers.
Das primäre Dichtmittel enthält bevorzugt Butylkautschuk, Polyisobutylen, Polyolefin- Kautschuk, Copolymere und/oder Gemische. The primary sealant preferably contains butyl rubber, polyisobutylene, polyolefin rubber, copolymers and / or blends.
Das Kunststoffprofil enthält bevorzugt mehr als eine Nut sodass auch Isolierverglasungen mit mehr als drei Scheiben hergestellt werden können. Isolierverglasungen mit mehr als drei Scheiben haben ein besseres Wärmedämmvermögen als Doppel- oder Dreifachisolierverglasungen. The plastic profile preferably contains more than one groove so that insulating glazings with more than three panes can be produced. Insulating glazings with more than three panes have better thermal insulation properties than double or triple glazing.
Die Nut weist bevorzugt eine Tiefe von 1 mm bis 15 mm, besonders bevorzugt von 2 mm bis 4 mm auf. Dadurch kann eine stabile Fixierung der dritten Scheibe erreicht werden. The groove preferably has a depth of 1 mm to 15 mm, particularly preferably 2 mm to 4 mm. As a result, a stable fixation of the third disc can be achieved.
Die Wandstärke d des Kunststoffprofils beträgt 0,5 mm bis 15 mm, bevorzugt 0,5 mm bis 10 mm, besonders bevorzugt 0,7 mm bis 1 mm. Dadurch wird eine stabile Fixierung des Abstands zwischen den einzelnen Scheiben erreicht und eine effiziente Stabilisierung des Grundkörpers zur Verhinderung des Girlandeneffekts erzielt. The wall thickness d of the plastic profile is 0.5 mm to 15 mm, preferably 0.5 mm to 10 mm, particularly preferably 0.7 mm to 1 mm. As a result, a stable fixation of the distance between the individual panes is achieved and an efficient stabilization of the main body to prevent the garland effect is achieved.
Der Scheibenzwischenraum der Isolierverglasung ist bevorzugt mit einem Schutzgas, bevorzugt mit einem Edelgas, vorzugsweise Argon oder Krypton gefüllt, die den Wärmeübergangswert im Scheibenzwischenraum reduzieren. The space between the panes of the insulating glazing is preferably filled with a protective gas, preferably with a noble gas, preferably argon or krypton, which reduce the heat transfer value in the space between the panes.
Die erste Scheibe und/oder die zweite und/oder die dritte Scheibe enthalten Glas und/oder Polymere, bevorzugt Quarzglas, Borosilikatglas, Kalk-Natron-Glas, Polymethylmethacrylat und/oder Gemische davon. Über die dritte Scheibe hinausgehende weitere Scheiben umfassen ebenfalls diese Materialien. The first pane and / or the second and / or the third pane contain glass and / or polymers, preferably quartz glass, borosilicate glass, soda lime glass, polymethyl methacrylate and / or mixtures thereof. Other discs extending beyond the third disc also include these materials.
Die Scheiben verfügen über eine Dicke von 1 mm bis 50 mm, bevorzugt 3 mm bis 16 mm, besonders bevorzugt 3 mm bis 10 mm, wobei die Scheiben auch unterschiedliche Dicken haben können. Eine Variation der Dicken der Scheiben verbessert den Schallschutz (asymmetrischer Aufbau). Die einzelnen Scheiben können einfache Glasscheiben sein oder Verbundglasscheiben, die zum Beispiel spezielle Schallschutzfolien enthalten, um neben einem Wärme-dämmenden auch einen Schall-dämmenden Effekt zu erzielen. Zur Verbesserung der Wärmeisolierung können auch sogenannte Low-E- Beschichtungen eingesetzt werden, die eine effektive Möglichkeit bieten, Infrarotstrahlung bereits vor Eintritt in den Wohnraum abzuschirmen und gleichzeitig Tageslicht hindurchzulassen. Low-E-Beschichtungen sind Wärmestrahlung reflektierende Beschichtungen, die einen erheblichen Teil der Infrarotstrahlung reflektieren, was im Sommer zu einer verringerten Erwärmung des Wohnraums führt. Die verschiedensten Low-E-Beschichtungen sind beispielsweise bekannt aus DE 10 2009 006 062 A1 , WO 2007/101964 A1 , EP 0 912 455 B1 , DE 199 27 683 C1 , EP 1 218 307 B1 und EP 1 917 222 B1 . Derartige Low-E-Beschichtungen können nicht auf der mittleren Scheibe einer Dreifachverglasung nach dem Stand der Technik aufgebracht werden, da die Beschichtung bei Sonneneinstrahlung eine Erwärmung der Scheibe bedingt, die zu einem Versagen der Klebeverbindung zwischen mittlerer Scheibe und Abstandshaltern führt. Ferner erzeugt eine Verklebung der mittleren Scheibe mit Funktionsbeschichtung zusätzliche Spannungen. Zur Kompensation dieser Spannungen muss die mittlere Scheibe nach dem Stand der Technik vorgespannt werden. Der erfindungsgemäße Abstandhalter mit einem Kunststoffprofil enthaltend eine Nut dagegen ermöglicht die Herstellung einer Isolierverglasung mit einer Low-E- Beschichtung auf der dritten Scheibe, ohne dass ein Vorspannen der dritten Scheibe notwendig ist. Dadurch entfällt der Vorspannprozess, wodurch eine weitere Kostenreduzierung erreicht werden kann. Durch die erfindungsgemäße spannungsfreie Fixierung in einer Nut kann ferner die Dicke und somit das Gewicht der dritten Scheibe vorteilhaft reduziert werden. The discs have a thickness of 1 mm to 50 mm, preferably 3 mm to 16 mm, particularly preferably 3 mm to 10 mm, wherein the discs may also have different thicknesses. A variation of the thicknesses of the discs improves the soundproofing (asymmetric construction). The individual panes may be simple glass panes or laminated glass panes containing, for example, special soundproofing foils, in addition to a heat-insulating and to achieve a sound-insulating effect. To improve the thermal insulation, so-called low-E coatings can be used, which provide an effective way to shield infrared radiation before entering the living room and at the same time let natural light through. Low-E coatings are thermal radiation reflective coatings that reflect a significant portion of the infrared radiation, resulting in reduced warming of the living space in the summer. The various low-E coatings are known, for example, from DE 10 2009 006 062 A1, WO 2007/101964 A1, EP 0 912 455 B1, DE 199 27 683 C1, EP 1 218 307 B1 and EP 1 917 222 B1. Such low-E coatings can not be applied to the middle pane of a prior art triple glazing because, when exposed to sunlight, the coating causes heating of the pane which results in failure of the adhesive bond between the center pane and spacers. Furthermore, adhesion of the functionalized center disk creates additional stresses. To compensate for these stresses, the center disc must be biased in the prior art. The spacer according to the invention with a plastic profile containing a groove, however, allows the production of a double glazing with a low-E coating on the third disc, without biasing the third disc is necessary. This eliminates the biasing process, which can be achieved further cost reduction. By virtue of the tension-free fixing in a groove according to the invention, furthermore, the thickness and thus the weight of the third disk can advantageously be reduced.
Die Erfindung umfasst ferner ein Verfahren zur Herstellung einer erfindungsgemäßen Isolierverglasung umfassend die Schritte: The invention further comprises a method for producing an insulating glazing according to the invention comprising the steps:
- Einsetzen einer dritten Scheibe in einer Nut eines Kunststoffprofils,  Inserting a third disc in a groove of a plastic profile,
- Einsetzten des Kunststoffprofils mit vormontierter dritter Scheibe zwischen einer ersten und einer zweiten Scheibe  - Inserting the plastic profile with preassembled third disc between a first and a second disc
- Co-extrusion eines Grundkörpers umfassend ein Dichtmaterial mit Trockenmittel und ein primäres Dichtmittel auf dem Kunststoffprofil.  - Co-extrusion of a base body comprising a sealing material with desiccant and a primary sealant on the plastic profile.
In einer ersten Ausführungsform des Verfahrens zur Herstellung einer erfindungsgemäßen Isolierverglasung wird zunächst eine dritte Scheibe in einer Nut des Kunststoffprofils vormontiert. Zur Vormontage einer rechteckigen Scheibe kann das Kunststoffprofil zu einem einseitig offenen Rechteck vorgeformt werden. Dabei können beispielsweise drei Kunststoffprofile mit einem Gärungsschnitt versehen und an den Ecken miteinander verschweißt werden. In die U-förmig angeordneten Kunststoffprofile wird von der offenen Seite der Anordnung ausgehend die dritte Scheibe in die Nut des Kunststoffprofils eingeschoben. Die verbleibende offene Kante der dritten Scheibe wird daraufhin ebenfalls mit einem Kunststoffprofil geschlossen. Alternativ können die Profile auch auf den Scheibenrand geklemmt oder gesteckt werden, wenn die Nut entsprechend an die Scheibendicke angepasst ist. So können leicht Scheiben mit verschiedenen Geometrien verarbeitet werden. Nach dem Zusammenbau des vollständigen Kunststoffprofils um die dritte Scheibe wird das Kunststoffprofil zwischen einer ersten Scheibe und einer zweiten Scheibe eingesetzt. Das Kunststoffprofil kann dabei an den Seiten, die an der Scheibe anliegen sollen, zum Beispiel mit einem Klebemittel versehen werden und so fixiert werden. In einem weiteren Verfahrensschritt werden der Grundkörper und das primäre Dichtmittel um das Kunststoffprofil herum direkt im äußeren Scheibenzwischenraum co-extrudiert. Das extrudierte Material härtet aus und es entsteht eine dauerhaft stabile Klebeverbindung. In a first embodiment of the method for producing an insulating glazing according to the invention, first of all a third pane is formed in a groove the plastic profile pre-assembled. For preassembly of a rectangular disc, the plastic profile can be preformed to a rectangle open on one side. In this case, for example, three plastic profiles can be provided with a fermentation cut and welded together at the corners. In the U-shaped arranged plastic profiles, starting from the open side of the arrangement, the third disc is inserted into the groove of the plastic profile. The remaining open edge of the third disc is then also closed with a plastic profile. Alternatively, the profiles can also be clamped or plugged onto the edge of the pane if the groove is adapted to the pane thickness. This makes it easy to process discs with different geometries. After assembling the complete plastic profile around the third disc, the plastic profile is inserted between a first disc and a second disc. The plastic profile can be provided on the sides that should rest against the disc, for example, with an adhesive and so fixed. In a further method step, the main body and the primary sealant are co-extruded around the plastic profile directly in the outer space between the panes. The extruded material cures and creates a permanently stable adhesive bond.
In einer zweiten alternativen Ausführungsform des erfindungsgemäßen Verfahrens wird zunächst eine dritte Scheibe in die Nut des Kunststoffprofils eingesetzt und anschließend wird das Kunststoffprofil mit dem Grundkörper und primärem Dichtmittel versehen, die direkt auf dem Kunststoffprofil co-extrudiert werden. Die Verarbeitung des vormontierten Bauteils kann auf einer klassischen dem Fachmann bekannten Doppelverglasungsanlage erfolgen. Die kostspielige Installation zusätzlicher Anlagenkomponenten oder ein Zeitverlust bei Mehrfachdurchlauf einer Anlage, wie bei der Montage mehrerer einzelner Abstandhalter nach dem Stand der Technik, können somit vermieden werden. Dies ist vorteilhaft hinsichtlich eines Produktivitätsgewinns und einer Kostensenkung. Dazu werden die erste Scheibe und die zweite Scheibe an den zwei Scheibenkontaktflächen des Abstandhalters aus Kunststoffprofil, Grundkörper und primärem Dichtmittel angebracht, und die Anordnung wird im letzten Schritt verpresst, wodurch eine stabile Klebeverbindung erzeugt wird. Bevorzugt wird bei diesem Verfahren das primäre Dichtmittel auch an den Scheibenkontaktflächen angebracht, damit die Haftung an der ersten und zweiten Scheibe verbessert ist. Bevorzugt wird der innere Scheibenzwischenraum zwischen erster Scheibe und dritter Scheibe sowie zwischen zweiter Scheibe und dritter Scheibe mit einem Schutzgas gefüllt. In a second alternative embodiment of the method according to the invention, a third disc is first inserted into the groove of the plastic profile and then the plastic profile is provided with the main body and primary sealant, which are co-extruded directly on the plastic profile. The processing of the pre-assembled component can be carried out on a conventional double-glazing installation known to the person skilled in the art. The costly installation of additional system components or a loss of time in a multi-pass a system, as in the assembly of several individual spacers according to the prior art, can thus be avoided. This is advantageous in terms of productivity gain and cost reduction. For this purpose, the first disc and the second disc are attached to the two disc contact surfaces of the spacer made of plastic profile, base body and primary sealant, and the assembly is pressed in the last step, whereby a stable adhesive bond is produced. Preferably, in this method, the primary sealant is also attached to the disc contact surfaces, so that the adhesion to the first and second disc is improved. Preferably, the inner space between the disc between the first disc and the third disc and between the second disc and the third disc is filled with a protective gas.
Die Erfindung umfasst des Weiteren die Verwendung einer erfindungsgemäßen Isolierverglasung als Gebäudeinnenverglasung, Gebäudeaußenverglasung und/oder Fassadenverglasung. The invention further comprises the use of an insulating glazing according to the invention as building interior glazing, building exterior glazing and / or facade glazing.
Im Folgenden wird die Erfindung anhand von Zeichnungen näher erläutert. Die Zeichnungen sind rein schematische Darstellungen und nicht maßstabsgetreu. Sie schränken die Erfindung in keiner Weise ein. In the following the invention will be explained in more detail with reference to drawings. The drawings are purely schematic representations and not to scale.

Figuren 1 a, 1 b und 1 c zeigen eine schematische Darstellung der erfindungsgemäßen Isolierverglasung. Zwischen einer ersten Scheibe 1 und einer zweiten Scheibe 2 ist eine dritte Scheibe 3 angeordnet. Zwischen der ersten Scheibe 1 und der zweiten Scheibe 2 ist ein Abstandhalter 6 angebracht, der aus einem Kunststoffprofil 9, einem Grundkörper 1 1 enthaltend ein Dichtmaterial und ein Trockenmittel und einem primären Dichtmittel 10 besteht. Das Kunststoffprofil 9 trennt den inneren Scheibenzwischenraum 5 vom äußeren Scheibenzwischenraum 4. Das Kunststoffprofil 9 enthält eine Nut 14 zur Aufnahme der dritten Scheibe 3. Die Nut 14 verläuft parallel zu den Scheibenkontaktflächen 8.1 und 8.2 und ragt in den Grundkörper 1 1 hinein. In die Nut 14 ist die dritte Scheibe 3 über eine Einlage 15 eingesetzt. Die Einlage 15 umschließt die Kante der dritten Scheibe 3 und passt sich bündig in die Nut 14 ein. Die Einlage 15 besteht aus Ethylen-Propylen-Dien-Kautschuk. Die Einlage 15 fixiert die dritte Scheibe 3 spannungsfrei und kompensiert eine Wärmeausdehnung der Scheibe. Des Weiteren verhindert die Einlage 15 eine Geräuschentwicklung durch Verrutschen der dritten Scheibe 3. Das Kunststoffprofil 9 kann im Zuge des Herstellungsverfahrens zu einem vollständigen Rahmen um die dritte Scheibe 3 zusammengesetzt werden. Das Kunststoffprofil 9 weist an den Verglasungsinnenraumflächen 7.1 und 7.2 Öffnungen 13 auf, um eine Verbindung zwischen dem inneren Scheibenzwischenraum 5 und dem Grundkörper 1 1 herzustellen, um den Gasaustausch zu ermöglichen und die Aufnahme von Feuchtigkeit durch das Trockenmittel zu erlauben. Im äußeren Scheibenzwischenraum 4 ist an den Grundkörper 1 1 angrenzend ein primäres Dichtmittel 10 angebracht, das dasselbe Dichtmaterial wie der Grundkörper 1 1 enthalten kann. Die erste Scheibenkontaktfläche 8.1 und die zweite Scheiben- kontaktfläche 8.2 werden vom Kunststoffprofil 9 und dem primären Dichtmittel 10 gebildet. Verglichen mit einer Anordnung, in der die Scheibenkontaktflächen 8.1 und 8.2 auch vom Grundkörper 1 1 gebildet werden, sind die Verklebung und die Abdichtung verbessert, da das primäre Dichtmittel 10 bessere Hafteigenschaften hat als das Dichtmittel mit Trockenmittel. An das primäre Dichtmittel 10 angrenzend ist ein sekundäres Dichtmittel 12 im äußeren Scheibenzwischenraum 4 zwischen erster Scheibe 1 und zweiter Scheibe 2 angebracht, das zur Verklebung der beiden Scheiben 1 und 2 dient und die mechanische Stabilität der Isolierverglasung erhöht. Figures 1 a, 1 b and 1 c show a schematic representation of the insulating glazing according to the invention. Between a first disc 1 and a second disc 2, a third disc 3 is arranged. Between the first disc 1 and the second disc 2, a spacer 6 is attached, which consists of a plastic profile 9, a base body 1 1 containing a sealing material and a desiccant and a primary sealant 10. The plastic profile 9 separates the inner space between the panes 5 from the outer pane space 4. The plastic profile 9 includes a groove 14 for receiving the third disc 3. The groove 14 extends parallel to the disc contact surfaces 8.1 and 8.2 and projects into the main body 1 1 inside. In the groove 14, the third disc 3 is inserted via an insert 15. The insert 15 encloses the edge of the third disc 3 and fits flush into the groove 14 a. The insert 15 is made of ethylene-propylene-diene rubber. The insert 15 fixes the third disc 3 stress-free and compensates for thermal expansion of the disc. Furthermore, the insert 15 prevents noise by slipping the third disc 3. The plastic profile 9 can be assembled in the course of the manufacturing process to form a complete frame around the third disc 3. The plastic profile 9 has on the glazing interior surfaces 7.1 and 7.2 openings 13 to establish a connection between the inner space between the panes 5 and the main body 1 1 to allow gas exchange and to allow the absorption of moisture by the desiccant. In the outer space between the panes 4 a primary sealing means 10 is attached to the base body 1 1, which may contain the same sealing material as the base body 1 1. The first disk contact surface 8.1 and the second disk contact surface 8.2 are formed by the plastic profile 9 and the primary sealing means 10. Compared with an arrangement in which the disc contact surfaces 8.1 and 8.2 are also formed by the main body 1 1, the bonding and the sealing are improved because the primary sealant 10 has better adhesive properties than the sealant with desiccant. Adjacent to the primary sealant 10, a secondary sealant 12 is mounted in the outer space between the panes 4 between the first pane 1 and the second pane 2, which serves to bond the two panes 1 and 2 and increases the mechanical stability of the double glazing.
Figur 2 zeigt ein Flussdiagramm einer möglichen Ausführungsform des erfindungsgemäßen Verfahrens. Zunächst wird eine dritte Scheibe 3 bereitgestellt und gewaschen. Optional wird eine Einlage 15 auf die Kanten der dritten Scheibe 3 aufgebracht. Die dritte Scheibe 3 wird nun in die Nut 14 des Kunststoffprofils 9 eingeschoben. Dabei wird ein vollständiger Profilrahmen um die dritte Scheibe 3 ausgebildet. Dies kann durch Aufstecken von vier Kunststoffprofilen an die Kanten der Scheibe erfolgen, oder drei Kunststoffprofile können zu einem an einer Seite offenen Rechteck vorgeformt werden, wobei die dritte Scheibe 3 über die offene Seite in die Nut 14 geschoben wird. Die Ecken können bei Bedarf über Eckverbinder verknüpft werden oder verschweißt werden. Die so vormontierte Scheibe kann daraufhin in einer klassischen Doppelverglasungsanlage weiterverarbeitet werden. Dort erfolgt die Montage der ersten Scheibe 1 und der zweiten Scheibe 2 an den Scheibenkontaktflächen 8.1 und 8.2. Optional kann ein Schutzgas in den inneren Scheibenzwischenraum 5 eingebracht werden. In einem letzten Schritt wird die Isolierverglasung verpresst.

This can be done by attaching four plastic profiles to the edges of the disc, or three plastic profiles can be preformed to a rectangle open on one side, the third disc 3 is pushed over the open side into the groove 14. If required, the corners can be linked via corner connectors or welded. The thus pre-assembled pane can then be further processed in a classic double-glazing system. There, the assembly of the first disc 1 and the second disc 2 takes place on the disc contact surfaces 8.1 and 8.2. Optionally, a protective gas can be introduced into the inner space between the panes 5. In a final step, the insulating glazing is pressed.

Dabei wird ein vollständiger Profilrahmen um die dritte Scheibe 3 ausgebildet. Das Kunststoffprofil 9 mit vormontierter dritter Scheibe 3 wird zwischen der ersten Scheibe 1 und der zweiten Scheibe 2 angeordnet. Dabei kann das Kunststoffprofil 9 an den Seiten mit Klebeband versehen werden, um es vor dem folgenden Verfahrensschritt zwischen den Scheiben 1 und 2 zu fixieren. Anschließend wird auf das Kunststoffprofil 9 im äußeren Scheibenzwischenraum 4 der Grundkörper 1 1 mit dem primären Dichtmittel 10 extrudiert. Optional kann der innere Scheibenzwischenraum 5 mit Schutzgas befüllt werden. FIG. 3 shows a flow chart of a possible embodiment of the method according to the invention. First, a third disk 3 is provided and washed. Optionally, an insert 15 is applied to the edges of the third disc 3. The third disc 3 is now in the groove 14 of the plastic profile. 9 inserted.
