Definitions

  • the invention relates to a spacer for insulating glazing, a method for its production, insulating glazing and its use.
  • the thermal conductivity of glass is about 2 to 3 times lower than that of concrete or similar building materials.
  • panes are in most cases significantly thinner than comparable elements made of stone or concrete, buildings often lose most of the heat through the external glazing.
  • the necessary additional costs for heating and air conditioning make up a part of the maintenance costs of a building that should not be underestimated.
  • lower carbon dioxide emissions are required as part of stricter building regulations.
  • An important solution for this is insulating glazing. Insulating glazing has become an indispensable part of building construction, especially in the wake of ever faster rising raw material prices and stricter environmental protection regulations. Insulating glazing therefore accounts for an increasingly large proportion of outward-facing glazing.
  • Insulating glazing usually contains at least two panes made of glass or polymeric materials.
  • the panes are separated from one another by a gas or vacuum space defined by the spacer.
  • the thermal insulation capacity of insulating glass is significantly higher than single glass and can be further increased and improved in triple glazing or with special coatings.
  • coatings containing silver enable reduced transmission of infrared radiation and thus reduce the heating of a building in summer.
  • optical and aesthetic features are also playing an increasingly important role in the field of building glazing.
  • the heat-insulating properties of insulating glazing are significantly influenced by the thermal conductivity in the area of the edge seal, in particular the spacer.
  • the high thermal conductivity of the metal causes a thermal bridge to form at the edge of the glass.
  • this thermal bridge leads to heat loss in the edge area of the insulating glazing and, on the other hand, to the formation of condensate on the inner pane in the area of the spacer in the event of high humidity and low outside temperatures.
  • thermally optimized, so-called "warm edge” systems are increasingly being used, in which the spacers are made of materials with lower thermal conductivity, such as plastics.
  • a challenge when using plastics is the correct sealing of the spacer. Leakages within the spacer can otherwise easily lead to a loss of an inert gas between the insulating glazing. In addition to a poorer insulating effect, leaks can also easily lead to moisture penetrating the insulating glazing. Precipitation between the panes of the insulating glazing caused by moisture significantly degrades the optical quality and in many cases makes it necessary to replace the entire insulating glazing.
  • One possible approach to improving the seal and reducing the thermal conductivity associated with this is the application of a barrier film to the spacer. This film is usually attached to the spacer in the area of the outer seal. Common foil materials include aluminum or stainless steel, which have good gas tightness. At the same time, the metal surface ensures good bonding of the spacer with the sealing compound.
  • WO2013/104507 A1 discloses a spacer with a polymer base body and an insulating film.
  • the insulating film contains a polymeric film and at least two metallic or ceramic layers, which are arranged alternating with at least one polymeric layer, the outermost layers preferably being polymeric layers.
  • the metallic layers are less than one ⁇ m thick and must be protected by polymer layers. Otherwise, the automated processing of the spacers when assembling the insulating glazing can easily damage the metallic layers.
  • EP 0 852 280 A1 discloses a spacer for multiple pane insulating glazing.
  • the spacer comprises a metal foil with a thickness of less than 0.1 mm on the bonding surface and glass fiber in the plastic of the base body.
  • the metal foil on the outside is exposed to high mechanical loads during further processing in the insulating glazing. In particular, when spacers are further processed on automated production lines, the metal foil is easily damaged and the barrier effect is thus impaired.
  • the object of the invention is to provide a spacer for insulating glazing which can be produced particularly inexpensively and which enables good sealing while at the same time being simple to assemble and thus contributes to an improved insulating effect which is stable over the long term.
  • the object of the present invention is achieved according to the invention by a spacer according to independent claim 1 .
  • Preferred embodiments emerge from the dependent claims.
  • a method for producing a spacer according to the invention, insulating glazing according to the invention and their use according to the invention arise from further independent claims.
  • the spacer according to the invention for multiple pane insulating glazing comprises at least one polymer base body and a multi-layer insulating film.
  • the base body comprises two parallel pane contact surfaces, a bonding surface and a glazing interior surface.
  • the pane contact surfaces and the bonding surface are connected to one another directly or alternatively via connecting surfaces.
  • the preferably two connecting surfaces preferably have an angle of 30° to 60° to the pane contact surfaces.
  • the insulating film is located on the bonding surface or the bonding surface and the connecting surfaces.
  • the insulating film comprises at least a metal-containing barrier layer, a polymeric layer and a metal-containing thin layer.
  • a thin layer in the context of the invention designates a layer with a thickness of less than 100 nm.
  • the metal-containing barrier layer has a thickness of 1 ⁇ m to 10 ⁇ m and seals the spacer against gas and moisture loss.
  • the metal-containing barrier layer faces the bonding surface and is connected to the bonding surface directly or via an adhesion promoter.
  • the layer facing the bonding surface is the layer of the insulating film which, of all the layers of the insulating film, is at the smallest distance from the bonding surface of the polymer base body.
  • the polymer layer has a thickness of 5 ⁇ m to 80 ⁇ m and is used for additional sealing. At the same time, the polymeric layer protects the metal-containing barrier layer from mechanical damage during storage and automated assembly of the insulating glazing.
  • the metal-containing thin film has a thickness of 5 nm to 30 nm. It was surprising that an additional barrier effect can be achieved by such a thin metal-containing layer.
  • the metal-containing thin layer is adjacent to the polymeric layer, which is particularly advantageous from a production point of view, since such films can be produced separately and are available at low cost.
  • the invention thus provides a spacer which has low thermal conductivity due to a low metal content, which is excellently sealed by a multiple barrier and which can also be produced inexpensively in large quantities due to the simple structure of the insulating film.
  • the metal-containing barrier layer is very well protected by the polymeric layer, so that no damage can occur to the otherwise sensitive metal-containing barrier layer.
  • the insulating film preferably consists of the metal-containing barrier layer, the polymeric layer and the metal-containing thin layer. A very good seal is already achieved with these three layers.
  • the individual layers can be connected via adhesives.
  • the metal-containing thin layer is on the outside and thus points away from the polymer base body.
  • the outermost layer is at the greatest distance from the adhesive surface of the polymer base body.
  • the metal-containing thin layer in the finished insulating glazing thus faces the sealing layer.
  • the sequence of layers in the insulation film, starting from the area to be bonded, is then: metal-containing barrier layer - polymer layer - metal-containing thin layer.
  • the thin film not only serves as an additional barrier against gas loss and moisture penetration, but also takes on the task of an adhesion promoter.
  • the adhesion of this thin layer to the usual materials of the outer sealing is so excellent that an additional adhesion promoter can be dispensed with.
  • the polymeric layer is on the outside, so that the sequence of layers in the insulating film, starting from the bonding area, is metal-containing barrier layer—metal-containing thin layer—polymeric layer.
  • the metal-containing barrier layer is also protected from damage.
  • the insulating film contains at least one second metal-containing thin layer.
  • Another metal-containing thin layer improves the barrier effect.
  • the metal-containing thin layer is preferably on the outside, so that it acts as an adhesion promoter.
  • a layer sequence in the insulating film starting from the bonding area metal-containing barrier layer--metal-containing thin layer--polymeric layer--metal-containing thin layer is particularly preferred.
  • the barrier effect is further improved by the second metal-containing thin layer, and at the same time the metal-containing thin layer on the outside acts as an adhesion promoter.
  • the metal-containing thin film is preferably deposited by a PVD process (physical vapor deposition). Coating processes for foils with metal-containing thin layers in the nanometer range are known and are used, for example, in the packaging industry.
  • the metal-containing thin layer can be applied to a polymeric film, for example by sputtering, in the required thickness of between 5 nm and 30 nm.
  • This coated film can then be laminated with a metal-containing barrier layer in a thickness in the ⁇ m range, and the insulating film for the spacer according to the invention can thus be obtained. Such a coating can be done on one side or on both sides.
  • an insulating film can be obtained in one production step which, in combination with the polymer base body, provides a spacer with excellent sealing.
  • the insulation film is preferred on the bonding surface, attached to the connecting surfaces and part of the disc contact surfaces.
  • the bonding surfaces and the connecting surfaces are completely covered by the insulating film and the pane contact surfaces are also partially covered.
  • the insulating film particularly preferably extends over two thirds or half the height h of the pane contact surfaces. A particularly good seal is achieved in this arrangement, since in the finished insulating glazing the insulating film overlaps with the sealant which is located between the panes and the pane contact surfaces. In this way, a possible diffusion of moisture into the interior of the pane and a diffusion of gases into or out of the interior of the pane can be prevented.
  • the metal-containing barrier layer preferably contains aluminum, silver, copper and/or alloys or mixtures thereof.
  • the metal-containing layer particularly preferably contains aluminum.
  • Aluminum foils are characterized by particularly good gas tightness.
  • the metallic layer has a thickness of 5 ⁇ m to 10 ⁇ m, particularly preferably 6 ⁇ m to 9 ⁇ m. A particularly good tightness of the insulating film could be observed within the mentioned layer thicknesses. Since the metal-containing barrier layer in the structure according to the invention is protected by a polymer layer, thinner metal-containing layers can be used compared to commercially available spacers (about 30 ⁇ m to 100 ⁇ m thickness of the metal-containing layers), which improves the heat-insulating properties of the spacer.
  • the metal-containing thin film preferably contains metals and/or metal oxides.
  • Metal oxides in particular provide good adhesion to the outer seal materials when the thin film is on the outside.
  • the metal-containing thin layer particularly preferably consists of aluminum and/or aluminum oxide. These materials create good adhesion and at the same time have a particularly good barrier effect.
  • the metal-containing thin layer preferably has a thickness of 10 nm to 30 nm, particularly preferably 15 nm. A good additional barrier effect is achieved with such a thickness without the thermal properties being impaired by the formation of a thermal bridge.
  • the insulating film is bonded to the bonding surface using a non-gassing adhesive, such as a polyurethane hot-melt adhesive that hardens under moisture.
  • a non-gassing adhesive such as a polyurethane hot-melt adhesive that hardens under moisture.
  • This adhesive creates a particularly good adhesion between the glass fiber reinforced polymer base body and the metal-containing barrier layer and prevents the formation of gases that diffuse through the spacer into the interior of the pane.
  • the insulating film preferably has a gas permeation of less than 0.001 g/(m 2 h).
  • the insulating film can be applied to the base body, for example glued. Alternatively, the insulating film can be coextruded together with the base body.
  • the polymeric layer preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polyacrylates, polymethyl acrylates and/or copolymers or mixtures thereof.
  • the polymeric layer preferably has a thickness of 5 ⁇ m to 24 ⁇ m, particularly preferably 12 ⁇ m. With these thicknesses, the underlying metallic barrier layer is particularly well protected.
  • the base body preferably has a width b of 5 mm to 45 mm, particularly preferably 8 mm to 20 mm, along the interior surface of the glazing.
  • the exact diameter depends on the dimensions of the insulating glazing and the desired size of the gap.
  • the base body preferably has an overall height g of 5.5 mm to 8 mm, particularly preferably 6.5 mm, along the pane contact surfaces.
  • the base body preferably contains a desiccant, preferably silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and/or mixtures thereof.
  • the desiccant can be incorporated either within a central cavity or in the glass fiber reinforced polymer body itself.
  • the desiccant is preferably contained within the central cavity.
  • the desiccant can then be filled in directly before assembling the insulating glazing. This ensures a particularly high absorption capacity of the desiccant in the finished insulating glazing.
  • the glazing interior surface preferably has openings which allow the moisture in the air to be absorbed by the desiccant contained in the base body.
  • the base body preferably contains polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polyester, polyurethane, polymethylmetacrylate, polyacrylate, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably 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 mixtures thereof.

  • the base body is preferably glass fiber reinforced.
  • the thermal expansion coefficient of the base body can be varied and adjusted by selecting the glass fiber content in the base body. By adapting the coefficient of thermal expansion of the base body and the insulating film, temperature-related stresses between the different materials and flaking of the insulating film can be avoided.
  • the base body preferably has a glass fiber content of 20% to 50%, particularly preferably 30% to 40%. The glass fiber content in the base body improves strength and stability at the same time.
  • the invention also includes insulating glazing comprising at least two panes, a spacer according to the invention arranged circumferentially between the panes in the edge region of the panes, a sealant and an outer sealing layer.

Description

Die Erfindung betrifft einen Abstandshalter für Isolierverglasungen, ein Verfahren zu dessen Herstellung, eine Isolierverglasung und deren Verwendung.The invention relates to a spacer for insulating glazing, a method for its production, insulating glazing and its use.

Die Wärmeleitfähigkeit von Glas ist etwa um den Faktor 2 bis 3 niedriger als die von Beton oder ähnlichen Baustoffen. Da Scheiben in den meisten Fällen jedoch deutlich dünner als vergleichbare Elemente aus Stein oder Beton ausgelegt sind, verlieren Gebäude dennoch häufig den größten Wärmeanteil über die Außenverglasung. Die notwendigen Mehrkosten für Heizung und Klimaanlagen machen einen nicht zu unterschätzenden Teil der Unterhaltungskosten eines Gebäudes aus. Zudem werden im Zuge strengerer Bauvorschriften niedrigere Kohlendioxid Emissionen gefordert. Ein wichtiger Lösungsansatz hierfür sind Isolierverglasungen. Isolierverglasungen sind vor allem im Zuge immer schneller steigender Rohstoffpreise und strengeren Umweltschutzauflagen nicht mehr aus dem Gebäudebau wegzudenken. Isolierverglasungen machen daher einen zunehmend größeren Teil der nach außen gerichteten Verglasungen aus. Isolierverglasungen enthalten in der Regel mindestens zwei Scheiben aus Glas oder polymeren Materialien. Die Scheiben sind über einen vom Abstandshalter (Spacer) definierten Gas- oder Vakuumraum voneinander getrennt. Das Wärmedämmvermögen von Isolierglas ist deutlich höher als Einfachglas und kann in Dreifachverglasungen oder mit speziellen Beschichtungen noch weiter gesteigert und verbessert werden. So ermöglichen beispielsweise silberhaltige Beschichtungen eine verringerte Transmission von infraroter Strahlung und senken so die Aufheizung eines Gebäudes im Sommer. Neben der wichtigen Eigenschaft der Wärmeisolierung spielen im Bereich der Gebäudeverglasung zunehmend auch optische und ästhetische Merkmale eine wichtige Rolle.The thermal conductivity of glass is about 2 to 3 times lower than that of concrete or similar building materials. However, since panes are in most cases significantly thinner than comparable elements made of stone or concrete, buildings often lose most of the heat through the external glazing. The necessary additional costs for heating and air conditioning make up a part of the maintenance costs of a building that should not be underestimated. In addition, lower carbon dioxide emissions are required as part of stricter building regulations. An important solution for this is insulating glazing. Insulating glazing has become an indispensable part of building construction, especially in the wake of ever faster rising raw material prices and stricter environmental protection regulations. Insulating glazing therefore accounts for an increasingly large proportion of outward-facing glazing. Insulating glazing usually contains at least two panes made of glass or polymeric materials. The panes are separated from one another by a gas or vacuum space defined by the spacer. The thermal insulation capacity of insulating glass is significantly higher than single glass and can be further increased and improved in triple glazing or with special coatings. For example, coatings containing silver enable reduced transmission of infrared radiation and thus reduce the heating of a building in summer. In addition to the important property of thermal insulation, optical and aesthetic features are also playing an increasingly important role in the field of building glazing.

Neben der Beschaffenheit und dem Aufbau des Glases sind auch die weiteren Komponenten einer Isolierverglasung von großer Bedeutung. Die Dichtung und vor allem der Abstandshalter haben einen großen Einfluss auf die Qualität der Isolierverglasung.In addition to the nature and structure of the glass, the other components of insulating glazing are also of great importance. The seal and above all the spacer have a major impact on the quality of the insulating glazing.

Die Wärme-isolierenden Eigenschaften von Isolierverglasungen werden ganz wesentlich vom Wärmeleitvermögen im Bereich des Randverbunds, insbesondere des Abstandhalters beeinflusst. Bei üblichen Abstandshaltern aus Aluminium kommt es durch die hohe thermische Leitfähigkeit des Metalls zur Ausbildung einer Wärmebrücke am Rand des Glases. Diese Wärmebrücke führt einerseits zu Wärmeverlusten im Randbereich der Isolierverglasung und andererseits bei hoher Luftfeuchtigkeit und niedrigen Außentemperaturen zur Bildung von Kondensat auf der Innenscheibe im Bereich des Abstandshalters. Um diese Probleme zu lösen, werden vermehrt thermisch optimierte, sogenannte "Warme-Kante"-Systeme eingesetzt, bei denen die Abstandhalter aus Materialien mit geringerer Wärmeleitfähigkeit, wie zum Beispiel Kunststoffen bestehen.The heat-insulating properties of insulating glazing are significantly influenced by the thermal conductivity in the area of the edge seal, in particular the spacer. With conventional aluminum spacers, the high thermal conductivity of the metal causes a thermal bridge to form at the edge of the glass. On the one hand, this thermal bridge leads to heat loss in the edge area of the insulating glazing and, on the other hand, to the formation of condensate on the inner pane in the area of the spacer in the event of high humidity and low outside temperatures. In order to solve these problems, thermally optimized, so-called "warm edge" systems are increasingly being used, in which the spacers are made of materials with lower thermal conductivity, such as plastics.

Eine Herausforderung bei der Verwendung von Kunststoffen ist die korrekte Abdichtung des Abstandhalters. Undichtigkeiten innerhalb des Abstandshalters können sonst leicht zu einem Verlust eines inerten Gases zwischen den Isolierverglasungen führen. Neben einer schlechteren Dämmwirkung können Undichtigkeiten zudem leicht zum Eindringen von Feuchtigkeit in die Isolierverglasung führen. Durch Feuchtigkeit gebildeter Niederschlag zwischen den Scheiben der Isolierverglasung verschlechtert ganz wesentlich die optische Qualität und macht in vielen Fällen einen Austausch der gesamten Isolierverglasung notwendig. Mögliche Ansätze zur Verbesserung der Abdichtung und eine damit verbundene Reduzierung der Wärmeleitfähigkeit ist die Aufbringung einer Barrierefolie auf dem Abstandshalter. Diese Folie wird in der Regel im Bereich der Außendichtung auf dem Abstandshalter befestigt. Gebräuchliche Folienmaterialien beinhalten Aluminium oder Edelstahl, welche eine gute Gasdichtigkeit aufweisen. Die Metalloberfläche gewährleistet gleichzeitig eine gute Verklebung des Abstandshalters mit der Dichtmasse.A challenge when using plastics is the correct sealing of the spacer. Leakages within the spacer can otherwise easily lead to a loss of an inert gas between the insulating glazing. In addition to a poorer insulating effect, leaks can also easily lead to moisture penetrating the insulating glazing. Precipitation between the panes of the insulating glazing caused by moisture significantly degrades the optical quality and in many cases makes it necessary to replace the entire insulating glazing. One possible approach to improving the seal and reducing the thermal conductivity associated with this is the application of a barrier film to the spacer. This film is usually attached to the spacer in the area of the outer seal. Common foil materials include aluminum or stainless steel, which have good gas tightness. At the same time, the metal surface ensures good bonding of the spacer with the sealing compound.

WO2013/104507 A1 offenbart einen Abstandhalter mit einem polymeren Grundkörper und einer Isolationsfolie. Die Isolationsfolie enthält dabei eine polymere Folie und mindestens zwei metallische oder keramische Schichten, die alternierend mit mindestens einer polymeren Schicht angeordnet sind, wobei bevorzugt die außen liegenden Schichten polymere Schichten sind. Die metallischen Schichten weisen eine Dicke unter einem µm auf und müssen durch polymere Schichten geschützt werden. Ansonsten kommt es bei der automatisierten Verarbeitung der Abstandhalter beim Zusammenbau der Isolierverglasungen leicht zu Beschädigungen der metallischen Schichten. WO2013/104507 A1 discloses a spacer with a polymer base body and an insulating film. The insulating film contains a polymeric film and at least two metallic or ceramic layers, which are arranged alternating with at least one polymeric layer, the outermost layers preferably being polymeric layers. The metallic layers are less than one µm thick and must be protected by polymer layers. Otherwise, the automated processing of the spacers when assembling the insulating glazing can easily damage the metallic layers.

EP 0 852 280 A1 offenbart einen Abstandshalter für Mehrscheiben-Isolierverglasungen. Der Abstandshalter umfasst eine Metallfolie mit einer Dicke unter 0,1 mm an der Verklebungsfläche und einen Glasfaseranteil im Kunststoff des Grundkörpers. Die außen liegende Metallfolie ist während der Weiterverarbeitung in der Isolierverglasung hohen mechanischen Belastungen ausgesetzt. Insbesondere wenn Abstandshalter auf automatisierten Fertigungslinien weiterverarbeitet werden, kommt es leicht zu Beschädigungen der Metallfolie und damit zur Verschlechterung der Barrierewirkung. EP 0 852 280 A1 discloses a spacer for multiple pane insulating glazing. The spacer comprises a metal foil with a thickness of less than 0.1 mm on the bonding surface and glass fiber in the plastic of the base body. The metal foil on the outside is exposed to high mechanical loads during further processing in the insulating glazing. In particular, when spacers are further processed on automated production lines, the metal foil is easily damaged and the barrier effect is thus impaired.

Die Aufgabe der Erfindung liegt darin, einen Abstandshalter für eine Isolierverglasung bereitzustellen, der besonders kostengünstig hergestellt werden kann und eine gute Abdichtung bei gleichzeitig einfacher Montage ermöglicht und so zu einer verbesserten langzeitstabilen Isolierwirkung beiträgt.The object of the invention is to provide a spacer for insulating glazing which can be produced particularly inexpensively and which enables good sealing while at the same time being simple to assemble and thus contributes to an improved insulating effect which is stable over the long term.

Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch einen Abstandshalter (Spacer) gemäß dem unabhängigen Anspruch 1 gelöst. Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor. Ein Verfahren zur Herstellung eines erfindungsgemäßen Abstandshalter, eine erfindungsgemäße Isolierverglasung und deren erfindungsgemäße Verwendung gehen aus weiteren unabhängigen Ansprüchen hervor.The object of the present invention is achieved according to the invention by a spacer according to independent claim 1 . Preferred embodiments emerge from the dependent claims. A method for producing a spacer according to the invention, insulating glazing according to the invention and their use according to the invention arise from further independent claims.

Der erfindungsgemäße Abstandshalter für Mehrfachscheiben-Isolierverglasung umfasst mindestens einen polymeren Grundkörper und eine mehrschichtige Isolationsfolie. Der Grundkörper umfasst zwei parallel verlaufende Scheibenkontaktflächen, eine Verklebungsfläche und eine Verglasungsinnenraumfläche. Die Scheibenkontaktflächen und die Verklebungsfläche sind direkt oder alternativ über Verbindungsflächen miteinander verbunden. Die bevorzugt zwei Verbindungsflächen weisen bevorzugt einen Winkel von 30° bis 60° zu den Scheibenkontaktflächen auf. Auf der Verklebungsfläche oder der Verklebungsfläche und den Verbindungsflächen befindet sich die Isolationsfolie. Die Isolationsfolie umfasst mindestens eine metallhaltige Barriereschicht, eine polymere Schicht und eine metallhaltige Dünnschicht. Eine Dünnschicht im Sinne der Erfindung bezeichnet eine Schicht mit einer Dicke unter 100 nm. Die metallhaltige Barriereschicht hat eine Dicke von 1 µm bis 10 µm und dichtet den Abstandhalter gegen Gas- und Feuchtigkeitsverlust ab. Die metallhaltige Barriereschicht weist zur Verklebungsfläche und ist mit der Verklebungsfläche direkt oder über einen Haftvermittler verbunden. Im Sinne der Erfindung ist die zur Verklebungsfläche weisende Schicht, die Schicht der Isolationsfolie, die von allen Schichten der Isolationsfolie den geringsten Abstand zur Verklebungsfläche des polymeren Grundkörpers hat. Die polymere Schicht hat eine Dicke von 5 µm bis 80 µm und dient der zusätzlichen Abdichtung. Die polymere Schicht schützt gleichzeitig die metallhaltige Barriereschicht vor mechanischer Beschädigung während der Lagerung und des automatisierten Zusammenbaus der Isolierverglasung. Die metallhaltige Dünnschicht weist eine Dicke von 5 nm bis 30 nm auf. Es war überraschend, dass durch eine so dünne metallhaltige Schicht eine zusätzliche Barrierewirkung erzielt werden kann. Die metallhaltige Dünnschicht grenzt an die polymere Schicht an, was aus produktionstechnischer Sicht besonders vorteilhaft ist, da derartige Folien separat hergestellt werden können und kostengünstig verfügbar sind.The spacer according to the invention for multiple pane insulating glazing comprises at least one polymer base body and a multi-layer insulating film. The base body comprises two parallel pane contact surfaces, a bonding surface and a glazing interior surface. The pane contact surfaces and the bonding surface are connected to one another directly or alternatively via connecting surfaces. The preferably two connecting surfaces preferably have an angle of 30° to 60° to the pane contact surfaces. The insulating film is located on the bonding surface or the bonding surface and the connecting surfaces. The insulating film comprises at least a metal-containing barrier layer, a polymeric layer and a metal-containing thin layer. A thin layer in the context of the invention designates a layer with a thickness of less than 100 nm. The metal-containing barrier layer has a thickness of 1 μm to 10 μm and seals the spacer against gas and moisture loss. The metal-containing barrier layer faces the bonding surface and is connected to the bonding surface directly or via an adhesion promoter. For the purposes of the invention, the layer facing the bonding surface is the layer of the insulating film which, of all the layers of the insulating film, is at the smallest distance from the bonding surface of the polymer base body. The polymer layer has a thickness of 5 µm to 80 µm and is used for additional sealing. At the same time, the polymeric layer protects the metal-containing barrier layer from mechanical damage during storage and automated assembly of the insulating glazing. The metal-containing thin film has a thickness of 5 nm to 30 nm. It was surprising that an additional barrier effect can be achieved by such a thin metal-containing layer. The metal-containing thin layer is adjacent to the polymeric layer, which is particularly advantageous from a production point of view, since such films can be produced separately and are available at low cost.

Somit wird durch die Erfindung ein Abstandhalter bereitgestellt, der eine geringe thermische Leitfähigkeit aufgrund eines geringen Metallanteils aufweist, der durch eine mehrfache Barriere hervorragend abgedichtet ist und der zudem aufgrund des einfachen Aufbaus der Isolationsfolie kostengünstig in großen Mengen herzustellen ist. Zudem ist die metallhaltige Barriereschicht durch die polymere Schicht sehr gut geschützt, sodass keine Beschädigung der ansonsten empfindlichen metallhaltigen Barriereschicht auftreten kann.The invention thus provides a spacer which has low thermal conductivity due to a low metal content, which is excellently sealed by a multiple barrier and which can also be produced inexpensively in large quantities due to the simple structure of the insulating film. In addition, the metal-containing barrier layer is very well protected by the polymeric layer, so that no damage can occur to the otherwise sensitive metal-containing barrier layer.

Die Isolationsfolie besteht bevorzugt aus der metallhaltigen Barriereschicht, der polymeren Schicht und der metallhaltigen Dünnschicht. Bereits mit diesen drei Schichten wird eine sehr gute Abdichtung erreicht. Die einzelnen Schichten können über Klebstoffe verbunden sein.The insulating film preferably consists of the metal-containing barrier layer, the polymeric layer and the metal-containing thin layer. A very good seal is already achieved with these three layers. The individual layers can be connected via adhesives.

In einer bevorzugten Ausführung des erfindungsgemäßen Abstandhalters liegt die metallhaltige Dünnschicht außen und weist somit vom polymeren Grundkörper weg. Erfindungsgemäß hat die außen liegende Schicht von allen Schichten der Isolationsfolie den größten Abstand zur Verklebungsfläche des polymeren Grundkörpers. Damit weist die metallhaltige Dünnschicht in der fertigen Isolierverglasung zur Versiegelungsschicht. Die Schichtenfolge in der Isolationsfolie ausgehend von der Verklebungsfläche ist dann: Metallhaltige Barriereschicht- polymere Schicht - metallhaltige Dünnschicht. In dieser Anordnung dient die Dünnschicht nicht nur als zusätzliche Barriere gegen Gasverlust und Eindringen von Feuchtigkeit sondern übernimmt gleichzeitig die Aufgabe eines Haftvermittlers. Die Haftung dieser dünnen Schicht zu den üblichen Materialien der äußeren Versiegelung ist so hervorragend, dass auf einen zusätzlichen Haftvermittler verzichtet werden kann.In a preferred embodiment of the spacer according to the invention, the metal-containing thin layer is on the outside and thus points away from the polymer base body. According to the invention, of all the layers of the insulating film, the outermost layer is at the greatest distance from the adhesive surface of the polymer base body. The metal-containing thin layer in the finished insulating glazing thus faces the sealing layer. The sequence of layers in the insulation film, starting from the area to be bonded, is then: metal-containing barrier layer - polymer layer - metal-containing thin layer. In this arrangement, the thin film not only serves as an additional barrier against gas loss and moisture penetration, but also takes on the task of an adhesion promoter. The adhesion of this thin layer to the usual materials of the outer sealing is so excellent that an additional adhesion promoter can be dispensed with.

In einer alternativen Ausführungsform liegt die polymere Schicht außen, sodass die Schichtenfolge in der Isolationsfolie ausgehend von der Verklebungsfläche metallhaltige Barriereschicht - metallhaltige Dünnschicht - polymere Schicht ist. In dieser Anordnung ist auch die metallhaltige Barriereschicht vor Beschädigung geschützt.In an alternative embodiment, the polymeric layer is on the outside, so that the sequence of layers in the insulating film, starting from the bonding area, is metal-containing barrier layer—metal-containing thin layer—polymeric layer. In this arrangement, the metal-containing barrier layer is also protected from damage.

In einer weiteren bevorzugten Ausführungsform enthält die Isolationsfolie mindestens eine zweite metallhaltige Dünnschicht. Eine weitere metallhaltige Dünnschicht verbessert die Barrierewirkung. Bevorzugt liegt die metallhaltige Dünnschicht außen, sodass sie als Haftvermittler wirkt. Besonders bevorzugt ist eine Schichtenfolge in der Isolationsfolie ausgehend von der Verklebungsfläche metallhaltige Barriereschicht - metallhaltige Dünnschicht - polymere Schicht - metallhaltige Dünnschicht. In dieser Anordnung ist die Barrierewirkung durch die zweite metallhaltige Dünnschicht weiter verbessert und gleichzeitig wirkt die außen liegende metallhaltige Dünnschicht als Haftvermittler.In a further preferred embodiment, the insulating film contains at least one second metal-containing thin layer. Another metal-containing thin layer improves the barrier effect. The metal-containing thin layer is preferably on the outside, so that it acts as an adhesion promoter. A layer sequence in the insulating film starting from the bonding area metal-containing barrier layer--metal-containing thin layer--polymeric layer--metal-containing thin layer is particularly preferred. In this arrangement, the barrier effect is further improved by the second metal-containing thin layer, and at the same time the metal-containing thin layer on the outside acts as an adhesion promoter.

Die metallhaltige Dünnschicht wird bevorzugt durch einen PVD-Prozess (physikalische Gasphasenabscheidung) abgeschieden. Beschichtungsverfahren für Folien mit metallhaltigen Dünnschichten im Nanometerbereich sind bekannt und werden zum Beispiel in der Verpackungsindustrie eingesetzt. Die metallhaltige Dünnschicht kann auf eine polymere Folie zum Beispiel durch Sputtern in der erforderlichen Dicke zwischen 5 nm und 30 nm aufgebracht werden. Anschließend kann diese beschichtete Folie mit einer metallhaltigen Barriereschicht in einer Dicke im µm-Bereich laminiert werden und so die Isolationsfolie für den erfindungsgemäßen Abstandshalter erhalten werden. Eine solche Beschichtung kann einseitig oder beidseitig erfolgen. So kann überraschend ausgehend von einem leicht zugänglichen Produkt in einem Produktionsschritt eine Isolationsfolie erhalten werden, die im Verbund mit dem polymeren Grundkörper einen Abstandhalter mit hervorragender Abdichtung liefert.The metal-containing thin film is preferably deposited by a PVD process (physical vapor deposition). Coating processes for foils with metal-containing thin layers in the nanometer range are known and are used, for example, in the packaging industry. The metal-containing thin layer can be applied to a polymeric film, for example by sputtering, in the required thickness of between 5 nm and 30 nm. This coated film can then be laminated with a metal-containing barrier layer in a thickness in the μm range, and the insulating film for the spacer according to the invention can thus be obtained. Such a coating can be done on one side or on both sides. Surprisingly, starting from an easily accessible product, an insulating film can be obtained in one production step which, in combination with the polymer base body, provides a spacer with excellent sealing.

Bevorzugt wird die Isolationsfolie an der Verklebungsfläche, den Verbindungsflächen und einem Teil der Scheibenkontaktflächen angebracht. In dieser Anordnung werden die Verklebungsflächen und die Verbindungsflächen vollständig von der Isolationsfolie bedeckt und zusätzlich die Scheibenkontaktflächen zu einem Teil bedeckt. Besonders bevorzugt erstreckt sich die Isolationsfolie über zwei Drittel oder die Hälfte der Höhe h der Scheibenkontaktflächen. In dieser Anordnung wird eine besonders gute Abdichtung erzielt, da in der fertigen Isolierverglasung die Isolationsfolie mit dem Dichtmittel überlappt, das sich zwischen den Scheiben und den Scheibenkontaktflächen befindet. So kann eine mögliche Diffusion von Feuchtigkeit in den Scheibeninnenraum und eine Diffusion von Gasen in den bzw. aus dem Scheibeninnenraum verhindert werden.The insulation film is preferred on the bonding surface, attached to the connecting surfaces and part of the disc contact surfaces. In this arrangement, the bonding surfaces and the connecting surfaces are completely covered by the insulating film and the pane contact surfaces are also partially covered. The insulating film particularly preferably extends over two thirds or half the height h of the pane contact surfaces. A particularly good seal is achieved in this arrangement, since in the finished insulating glazing the insulating film overlaps with the sealant which is located between the panes and the pane contact surfaces. In this way, a possible diffusion of moisture into the interior of the pane and a diffusion of gases into or out of the interior of the pane can be prevented.

Die metallhaltige Barriereschicht enthält bevorzugt Aluminium, Silber, Kupfer und/oder Legierungen oder Gemische davon. Besonders bevorzugt enthält die metallhaltige Schicht Aluminium. Aluminiumfolien zeichnen sich durch eine besonders gute Gasdichtigkeit aus. Die metallische Schicht weist eine Dicke von 5 µm bis 10 µm auf, besonders bevorzugt von 6 µm bis 9 µm auf. Innerhalb der genannten Schichtdicken konnte eine besonders gute Dichtigkeit der Isolationsfolie beobachtet werden. Da die metallhaltige Barriereschicht im erfindungsgemäßen Aufbau durch eine polymere Schicht geschützt wird, können im Vergleich zu handelsüblichen Abstandshaltern (ca. 30 µm bis 100 µm Dicke der metallhaltigen Schichten) dünnere metallhaltige Schichten eingesetzt werden, wodurch die Wärme-isolierenden Eigenschaften des Abstandshalters verbessert werden.The metal-containing barrier layer preferably contains aluminum, silver, copper and/or alloys or mixtures thereof. The metal-containing layer particularly preferably contains aluminum. Aluminum foils are characterized by particularly good gas tightness. The metallic layer has a thickness of 5 μm to 10 μm, particularly preferably 6 μm to 9 μm. A particularly good tightness of the insulating film could be observed within the mentioned layer thicknesses. Since the metal-containing barrier layer in the structure according to the invention is protected by a polymer layer, thinner metal-containing layers can be used compared to commercially available spacers (about 30 μm to 100 μm thickness of the metal-containing layers), which improves the heat-insulating properties of the spacer.

Die metallhaltige Dünnschicht enthält bevorzugt Metalle und/oder Metalloxide. Insbesondere Metalloxide stellen eine gute Haftung zu den Materialien der äußeren Versiegelung her, wenn die Dünnschicht außen liegt. Besonders bevorzugt besteht die metallhaltige Dünnschicht aus Aluminium und / oder Aluminiumoxid. Diese Materialien stellen eine gute Haftung her und haben gleichzeitig eine besonders gute Barrierewirkung.The metal-containing thin film preferably contains metals and/or metal oxides. Metal oxides in particular provide good adhesion to the outer seal materials when the thin film is on the outside. The metal-containing thin layer particularly preferably consists of aluminum and/or aluminum oxide. These materials create good adhesion and at the same time have a particularly good barrier effect.

Die metallhaltige Dünnschicht hat bevorzugt eine Dicke von 10 nm bis 30 nm, besonders bevorzugt von 15 nm. In einer solchen Dicke wird eine gute zusätzliche Barrierewirkung erzielt ohne dass es zu einer Verschlechterung der thermischen Eigenschaften durch Ausbildung einer Wärmebrücke kommt.The metal-containing thin layer preferably has a thickness of 10 nm to 30 nm, particularly preferably 15 nm. A good additional barrier effect is achieved with such a thickness without the thermal properties being impaired by the formation of a thermal bridge.

In einer bevorzugten Variante wird die Isolationsfolie mit der Verklebungsfläche über einen nichtgasenden Kleber verklebt, wie zum Beispiel einen Polyurethan-Schmelzklebstoff, der unter Feuchtigkeit aushärtet. Dieser Kleber stellt eine besonders gute Haftung zwischen dem glasfaserverstärkten polymeren Grundkörper und der metallhaltigen Barriereschicht her und vermeidet die Bildung von Gasen, die durch den Abstandhalter in den Scheibeninnenraum diffundieren.In a preferred variant, the insulating film is bonded to the bonding surface using a non-gassing adhesive, such as a polyurethane hot-melt adhesive that hardens under moisture. This adhesive creates a particularly good adhesion between the glass fiber reinforced polymer base body and the metal-containing barrier layer and prevents the formation of gases that diffuse through the spacer into the interior of the pane.

Die Isolationsfolie weist bevorzugt eine Gaspermeation von kleiner als 0,001 g/(m2 h) auf.The insulating film preferably has a gas permeation of less than 0.001 g/(m 2 h).

Die Isolationsfolie kann auf dem Grundkörper aufgebracht werden, beispielsweise geklebt werden. Alternativ kann die Isolationsfolie mit dem Grundkörper zusammen coextrudiert werden.The insulating film can be applied to the base body, for example glued. Alternatively, the insulating film can be coextruded together with the base body.

Die polymere Schicht umfasst bevorzugt Polyethylenterephthalat, Ethylenvinylalkohol, Polyvinylidenchlorid, Polyamide, Polyethylen, Polypropylen, Silikone, Acrylonitrile, Polyacrylate, Polymethylacrylate und/oder Copolymere oder Gemische davon.The polymeric layer preferably comprises polyethylene terephthalate, ethylene vinyl alcohol, polyvinylidene chloride, polyamides, polyethylene, polypropylene, silicones, acrylonitriles, polyacrylates, polymethyl acrylates and/or copolymers or mixtures thereof.

Die polymere Schicht weist bevorzugt eine Dicke von 5 µm bis 24 µm, besonders bevorzugt 12 µm, auf. Bei diesen Dicken wird die darunter liegende metallische Barriereschicht besonders gut geschützt.The polymeric layer preferably has a thickness of 5 μm to 24 μm, particularly preferably 12 μm. With these thicknesses, the underlying metallic barrier layer is particularly well protected.

Der Grundkörper weist bevorzugt entlang der Verglasungsinnenraumfläche eine Breite b von 5 mm bis 45 mm auf, besonders bevorzugt 8 mm bis 20 mm. Der genaue Durchmesser richtet sich nach den Abmessungen der Isolierverglasung und der gewünschten Zwischenraumgröße.The base body preferably has a width b of 5 mm to 45 mm, particularly preferably 8 mm to 20 mm, along the interior surface of the glazing. The exact diameter depends on the dimensions of the insulating glazing and the desired size of the gap.

Der Grundkörper weist bevorzugt entlang der Scheibenkontaktflächen eine Gesamthöhe g von 5,5 mm bis 8 mm, besonders bevorzugt 6,5 mm auf.The base body preferably has an overall height g of 5.5 mm to 8 mm, particularly preferably 6.5 mm, along the pane contact surfaces.

Der Grundkörper enthält bevorzugt ein Trockenmittel, bevorzugt Kieselgele, Molekularsiebe, CaCl2, Na2SO4, Aktivkohle, Silikate, Bentonite, Zeolithe und/oder Gemische davon. Das Trockenmittel kann sowohl innerhalb eines zentralen Hohlraums oder in den glasfaserverstärkten polymeren Grundkörper selbst eingearbeitet sein. Das Trockenmittel ist bevorzugt innerhalb des zentralen Hohlraums enthalten. Das Trockenmittel kann dann direkt vor dem Zusammenbau der Isolierverglasung eingefüllt werden. So wird eine besonders hohe Aufnahmekapazität des Trockenmittels in der fertigen Isolierverglasung sichergestellt. Die Verglasungsinnenraumfläche weist bevorzugt Öffnungen auf, welche eine Aufnahme der Luftfeuchtigkeit durch das im Grundkörper enthaltene Trockenmittel erlauben.The base body preferably contains a desiccant, preferably silica gels, molecular sieves, CaCl 2 , Na 2 SO 4 , activated carbon, silicates, bentonites, zeolites and/or mixtures thereof. The desiccant can be incorporated either within a central cavity or in the glass fiber reinforced polymer body itself. The desiccant is preferably contained within the central cavity. The desiccant can then be filled in directly before assembling the insulating glazing. This ensures a particularly high absorption capacity of the desiccant in the finished insulating glazing. The glazing interior surface preferably has openings which allow the moisture in the air to be absorbed by the desiccant contained in the base body.

Der Grundkörper enthält bevorzugt Polyethylen (PE), Polycarbonate (PC), Polypropylen (PP), Polystyrol, Polyester, Polyurethane, Polymethylmetacrylate, Polyacrylate, Polyamide, Polyethylenterephthalat (PET), Polybutylenterephthalat (PBT), bevorzugt 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.The base body preferably contains polyethylene (PE), polycarbonate (PC), polypropylene (PP), polystyrene, polyester, polyurethane, polymethylmetacrylate, polyacrylate, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), preferably 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 mixtures thereof.

Der Grundkörper ist bevorzugt glasfaserverstärkt. Durch die Wahl des Glasfaseranteils im Grundkörper kann der Wärmeausdehnungskoeffizient des Grundkörpers variiert und angepasst werden. Durch Anpassung des Wärmeausdehnungskoeffizienten des Grundkörpers und der Isolationsfolie lassen sich temperaturbedingte Spannungen zwischen den unterschiedlichen Materialien und ein Abplatzen der Isolationsfolie vermeiden. Der Grundkörper weist bevorzugt einen Glasfaseranteil von 20 % bis 50 %, besonders bevorzugt von 30 % bis 40 % auf. Der Glasfaseranteil im Grundkörper verbessert gleichzeitig die Festigkeit und Stabilität.The base body is preferably glass fiber reinforced. The thermal expansion coefficient of the base body can be varied and adjusted by selecting the glass fiber content in the base body. By adapting the coefficient of thermal expansion of the base body and the insulating film, temperature-related stresses between the different materials and flaking of the insulating film can be avoided. The base body preferably has a glass fiber content of 20% to 50%, particularly preferably 30% to 40%. The glass fiber content in the base body improves strength and stability at the same time.

Die Erfindung umfasst des Weiteren eine Isolierverglasung umfassend mindestens zwei Scheiben, einen zwischen den Scheiben im Randbereich der Scheiben umlaufend angeordneten erfindungsgemäßen Abstandshalter, ein Dichtmittel und eine äußere Versiegelungsschicht. Dabei liegt eine erste Scheibe an der ersten Scheibenkontaktfläche des Abstandshalters an und eine zweite Scheibe an der zweiten Scheibenkontaktfläche an. Zwischen der ersten Scheibe und der ersten Scheibenkontaktfläche und der zweiten Scheibe und der zweiten Scheibenkontaktfläche ist ein Dichtmittel angebracht. Die beiden Scheibe ragen über den Abstandshalter hinaus, so dass ein umlaufender Randbereich entsteht, der mit einer äußeren Versiegelungsschicht, bevorzugt einer plastischen Abdichtmasse, verfüllt ist. Der Randraum liegt dem inneren Scheibenzwischenraum gegenüber und wird durch die beiden Scheiben und den Abstandshalter begrenzt. Die äußere Versiegelungsschicht steht in Kontakt mit der Isolationsfolie des erfindungsgemäßen Abstandshalters. Die äußere Versiegelungsschicht enthält bevorzugt Polymere oder silanmodifizierte Polymere, besonders bevorzugt Polysulfide, Silikone, RTV (raumtemperturvernetzenden)-Silikonkautschuk, HTV-(hochtemperturvernetzenden) Silikonkautschuk, peroxidischvernetzten-Silikonkautschuk und/oder additionsvernetzten-Silikonkautschuk, Polyurethane, Buthylkautschuk und/oder Polyacrylate. Die Scheiben enthalten Materialien wie Glas und/oder transparente Polymere. Die Scheiben weisen bevorzugt eine optische Transparenz von > 85 % auf. Grundsätzlich sind verschiedene Geometrien der Scheiben möglich, beispielsweise rechteckige, trapezförmige und abgerundete Geometrien. Die Scheiben weisen bevorzugt eine Wärmeschutzbeschichtung auf. Die Wärmeschutzbeschichtung enthält bevorzugt Silber. Um Energieeinsparmöglichkeiten ausschöpfen zu können, kann die Isolierverglasung mit einem Edelgas, vorzugsweise Argon oder Krypton befüllt werden, die den Wärmeübergangswert im Isolierverglasungszwischenraum reduzieren.The invention also includes insulating glazing comprising at least two panes, a spacer according to the invention arranged circumferentially between the panes in the edge region of the panes, a sealant and an outer sealing layer. A first pane bears against the first pane contact surface of the spacer and a second pane bears against the second pane contact surface. A sealant is applied between the first disc and the first disc contacting surface and the second disc and the second disc contacting surface. The two panes protrude beyond the spacer, so that a peripheral edge area is created which is filled with an outer sealing layer, preferably a plastic sealing compound. The edge space is opposite the inner space between the panes and is delimited by the two panes and the spacer. The outer sealing layer is in contact with the insulating film of the spacer according to the invention. The outer sealing layer preferably contains polymers or silane-modified polymers, particularly preferably polysulfides, silicones, RTV (room temperature crosslinking) silicone rubber, HTV (high temperature crosslinking) silicone rubber, peroxide-crosslinked silicone rubber and/or addition-crosslinked silicone rubber, polyurethanes, butyl rubber and/or polyacrylates. The panes contain materials such as glass and/or transparent polymers. The panes preferably have an optical transparency of >85%. In principle, different geometries of the discs are possible, for example rectangular, trapezoidal and rounded geometries. The panes preferably have a heat protection coating. The thermal barrier coating preferably contains silver. In order to be able to exploit energy-saving opportunities, the insulating glazing can be filled with an inert gas, preferably argon or krypton, which reduces the heat transfer value in the space between the insulating glazing.

Die Erfindung umfasst weiterhin ein Verfahren zur Herstellung eines erfindungsgemäßen Abstandshalters umfassend die Schritte

  • Extrusion des polymeren Grundkörpers,
  • Herstellung der Isolationsfolie durch
    1. a) Aufbringen der metallhaltigen Dünnschicht auf der polymeren Schicht durch einen PVD-Prozess (physikalische Gasphasenabscheidung)
    2. b) Laminieren des erhaltenen Schichtaufbaus mit der metallhaltigen Barriereschicht und
  • Anbringung der Isolationsfolie auf dem polymeren Grundkörper.
The invention also includes a method for producing a spacer according to the invention comprising the steps
  • extrusion of the polymer base body,
  • Production of the insulation film
    1. a) Application of the metal-containing thin layer on the polymer layer by a PVD process (physical vapor deposition)
    2. b) laminating the layer structure obtained with the metal-containing barrier layer and
  • Attachment of the insulating film to the polymer base body.

Der polymere Grundkörper wird durch Extrusion hergestellt. In einem weiteren Schritt wird die Isolationsfolie hergestellt. Zunächst wird dazu eine polymere Folie in einem PVD-Prozess metallisiert. Dadurch erhält man den für die Isolationsfolie benötigten Aufbau aus polymerer Schicht und metallhaltiger Dünnschicht. Dieser Prozess wird für die Herstellung von Folien in der Verpackungsindustrie bereits im großen Maßstab angewendet, sodass der Schichtaufbau aus polymerer Schicht und metallhaltiger Dünnschicht kostengünstig hergestellt werden kann. In einem weiteren Schritt wird die metallisierte polymere Schicht mit der metallhaltigen Barriereschicht laminiert. Dazu wird eine dünne Metallfolie (entspricht der metallhaltigen Barriereschicht) mit der vorbereiteten metallisierten polymeren Schicht durch Lamination verbunden.
Die metallhaltige Barriereschicht kann sowohl auf der polymeren Schicht als auch auf der metallhaltigen Dünnschicht angebracht werden. Im ersten Fall liegt die metallhaltige Dünnschicht in der fertigen Isolationsfolie außen und kann so nach dem Anbringen auf dem Abstandhalter auch als Haftvermittler zum Material der äußeren Versiegelung dienen. Im zweiten Fall liegt die metallhaltige Dünnschicht innen und ist so vor Beschädigungen geschützt.The polymer base body is produced by extrusion. In a further step, the insulating film is produced. First, a polymer film is metallized in a PVD process. This gives the structure required for the insulating film, consisting of a polymer layer and a metal-containing thin layer. This process is already used on a large scale for the production of foils in the packaging industry, so that the layered structure consisting of a polymer layer and a metal-containing thin layer can be produced cost-effectively. In a further step, the metalized polymeric layer is laminated with the metal-containing barrier layer. For this purpose, a thin metal foil (corresponds to the metal-containing barrier layer) is connected to the prepared metallized polymer layer by lamination.
The metal-containing barrier layer can be applied both to the polymeric layer and to the metal-containing thin layer. In the first case, the metal-containing thin layer is on the outside of the finished insulation film and can therefore also serve as an adhesion promoter for the material of the outer seal after it has been attached to the spacer. In the second case, the metal-containing thin layer is on the inside and is thus protected from damage.

Die Isolationsfolie wird bevorzugt über einen Kleber auf der Verklebungsfläche des polymeren Grundkörpers angebracht.The insulating film is preferably attached to the bonding surface of the polymer base body using an adhesive.

Die Erfindung umfasst weiterhin die Verwendung eines erfindungsgemäßen Abstandshalters in Mehrfachverglasungen, bevorzugt in Isolierverglasungen.The invention also includes the use of a spacer according to the invention in multiple glazing, preferably in insulating glazing.

Figur 1 zeigt einen Querschnitt des erfindungsgemäßen Abstandshalters 1. Der glasfaserverstärkte polymere Grundkörper 2 umfasst zwei parallel verlaufende Scheibenkontaktflächen 3.1 und 3.2, welche den Kontakt zu den Scheiben einer Isolierverglasung herstellen. Die Scheibenkontaktflächen 3.1 und 3.2 sind über eine äußere Verklebungsfläche 5 und eine Verglasungsinnenraumfläche 4 verbunden. Zwischen der Verklebungsfläche 5 und den Scheibenkontaktflächen 3.1 und 3.2 sind bevorzugt zwei gewinkelte Verbindungsflächen 6.1 und 6.2 angeordnet. Die Verbindungsflächen 6.1, 6.2 verlaufen bevorzugt in einem Winkel □ (Alfa) von 30° bis 60° zur Verklebungsfläche 5. Der glasfaserverstärkte polymere Grundkörper 2 enthält bevorzugt Styrol-Acryl-Nitril (SAN) und etwa 35 Gew.-% Glasfaser. Die abgewinkelte Form der ersten Verbindungsfläche 6.1 und der zweiten Verbindungsfläche 6.2 verbessert die Stabilität des glasfaserverstärkten polymeren Grundkörpers 2 und ermöglicht wie in Figur 2 gezeigt eine bessere Verklebung und Isolierung des erfindungsgemäßen Abstandshalters. Der Grundkörper weist einen Hohlraum 8 auf und die Wandstärke des polymeren Grundkörpers 2 beträgt zum Beispiel 1 mm. Die Breite b (siehe Figur 5) des polymeren Grundkörpers 2 entlang der Verglasungsinnenraumfläche 4 beträgt zum Beispiel 12 mm. Die Gesamthöhe des polymeren Grundkörpers beträgt 6,5 mm. Auf der Verklebungsfläche 5 ist eine Isolationsfolie 10 angebracht, welche mindestens eine in Figur 3 gezeigte metallhaltige Barriereschicht 12, eine polymere Schicht 13 sowie eine metallhaltige Dünnschicht 14 umfasst. Der gesamte erfindungsgemäße Abstandshalter weist eine Wärmeleitfähigkeit von kleiner als 10 W/(m K) und eine Gaspermeation von kleiner 0,001 g/(m2 h) auf. Der erfindungsgemäße Abstandshalter verbessert die Isolationswirkung. figure 1 shows a cross section of the spacer 1 according to the invention. The glass fiber reinforced polymer base body 2 comprises two parallel pane contact surfaces 3.1 and 3.2, which establish contact with the panes of insulating glazing. The pane contact surfaces 3.1 and 3.2 are connected via an outer adhesive surface 5 and an interior surface 4 of the glazing. Between the bonding surface 5 and the pane contact surfaces 3.1 and 3.2, two angled connecting surfaces 6.1 and 6.2 are preferably arranged. The connecting surfaces 6.1, 6.2 preferably run at an angle □ (Alfa) of 30° to 60° to the adhesive surface 5. The glass-fiber-reinforced polymer base body 2 preferably contains styrene-acrylic-nitrile (SAN) and about 35% by weight glass fiber. The angled shape of the first connecting surface 6.1 and the second connecting surface 6.2 improves the stability of the glass fiber reinforced polymer base body 2 and, as in figure 2 shown better bonding and insulation of the spacer according to the invention. The base body has a cavity 8 and the wall thickness of the polymeric base body 2 is 1 mm, for example. The width b (see figure 5 ) of the polymer base body 2 along the glazing interior surface 4 is 12 mm, for example. The overall height of the polymer body is 6.5 mm. An insulating film 10 is attached to the bonding surface 5, which has at least one in figure 3 shown metal-containing barrier layer 12, a polymeric layer 13 and a metal-containing thin layer 14 comprises. The entire spacer according to the invention has a thermal conductivity of less than 10 W/(m K) and a gas permeation of less than 0.001 g/(m 2 h). The spacer according to the invention improves the insulating effect.

Figur 2 zeigt einen Querschnitt der erfindungsgemäßen Isolierverglasung mit dem Abstandshalter 1 beschrieben in Figur 1. Zwischen einer ersten Isolierglasscheibe 15 und einer zweiten Isolierglasscheibe 16 ist der glasfaserverstärkte polymere Grundkörper 2 mit der darauf befestigten Isolationsfolie 10 angeordnet. Die Isolationsfolie 10 ist auf der Verklebungsfläche 5, der ersten Verbindungsfläche 6.1 und der zweiten Verbindungsfläche 6.2 und auf einem Teil der Scheibenkontaktflächen angeordnet. Die erste Scheibe 15, die zweite Scheibe 16 und die Isolationsfolie 10 begrenzen den äußeren Randraum 20 der Isolierverglasung. Im äußeren Randraum 20 ist die äußere Versiegelungsschicht 17, die zum Beispiel Polysulfid enthält angeordnet. Die Isolationsfolie 10 isoliert zusammen mit der äußeren Versiegelungsschicht 17 den Scheibeninnenraum 19 und vermindert den Wärmeübergang vom glasfaserverstärkten polymeren Grundkörper 2 in den Scheibeninnenraum 19. Die Isolationsfolie kann beispielsweise mit PUR-Hotmeltkleber auf dem polymeren Grundkörper 2 befestigt werden. Zwischen den Scheibenkontaktflächen 3.1, 3.2 und den Isolierglasscheiben 15, 16 ist bevorzugt ein Dichtmittel 18 angeordnet. Dies enthält zum Beispiel Butyl. Das Dichtmittel 18 überlappt mit der Isolationsfolie, um mögliche Grenzflächendiffusion zu verhindern. Die erste Isolierglasscheibe 15 und die zweite Isolierglasscheibe 16 weisen bevorzugt dieselben Abmessungen und Dicken auf. Die Scheiben weisen bevorzugt eine optische Transparenz von > 85 % auf. Die Isolierglasscheiben 15,16 enthalten bevorzugt Glas und/oder Polymere, bevorzugt Flachglas, Floatglas, Quarzglas, Borosilikatglas, Kalk-Natron-Glas, Polymethylmethacrylat und/oder Gemische davon. In einer alternativen Ausführungsform können die erste Isolierglasscheibe 15 und/oder die zweite Isolierglasscheibe 16 als Verbundglasscheibe ausgebildet sein. Die erfindungsgemäße Isolierverglasung bildet in diesem Fall eine Dreifach- oder Vierfachverglasung. Innerhalb des glasfaserverstärkten polymeren Grundkörpers 2 ist ein Trockenmittel 9, zum Beispiel Molsieb, innerhalb des zentralen Hohlraums 8 angeordnet. Dieses Trockenmittel 9 kann in den Hohlraum 8 des Abstandshalters 1 vor dem Zusammenbau der Isolierverglasung eingefüllt werden. Die Verglasungsinnenraumfläche 4 umfasst kleinere Öffnungen 7 oder Poren, die einen Gasaustausch mit dem Scheibeninnenraum 19 ermöglichen. figure 2 shows a cross section of the insulating glazing according to the invention with the spacer 1 described in figure 1 . Between a first insulating glass pane 15 and a second insulating glass pane 16, the glass fiber reinforced polymer base body 2 with the insulating film 10 attached thereto is arranged. The insulating film 10 is arranged on the bonding surface 5, the first connecting surface 6.1 and the second connecting surface 6.2 and on part of the pane contact surfaces. The first pane 15, the second pane 16 and the insulating film 10 delimit the outer edge space 20 of the insulating glazing. The outer sealing layer 17, which contains polysulfide, for example, is arranged in the outer edge space 20. The insulating film 10, together with the outer sealing layer 17, insulates the interior 19 of the pane and reduces the heat transfer from the glass fiber-reinforced polymeric base body 2 to the interior of the pane 19. The insulating film can be attached to the polymeric base body 2 with PUR hotmelt adhesive, for example. A sealant 18 is preferably arranged between the pane contact surfaces 3.1, 3.2 and the insulating glass panes 15, 16. This includes, for example, butyl. The sealant 18 overlaps the insulating film to prevent possible interfacial diffusion. The first insulating glass pane 15 and the second insulating glass pane 16 preferably have the same dimensions and thicknesses. The panes preferably have an optical transparency of >85%. The insulating glass panes 15, 16 preferably contain glass and/or polymers, preferably flat glass, float glass, quartz glass, borosilicate glass, soda-lime glass, polymethyl methacrylate and/or mixtures thereof. In an alternative embodiment, the first insulating glass pane 15 and/or the second insulating glass pane 16 can be designed as a laminated glass pane. In this case, the insulating glazing according to the invention forms triple or quadruple glazing. A desiccant 9 , for example a molecular sieve, is arranged within the central cavity 8 within the glass-fiber-reinforced polymer base body 2 . This desiccant 9 can be filled into the cavity 8 of the spacer 1 before assembling the insulating glazing. The glazing interior surface 4 includes smaller openings 7 or pores that allow gas exchange with the interior 19 of the pane.

Figur 3 zeigt einen Querschnitt der erfindungsgemäßen Isolationsfolie 10. Die Isolationsfolie 10 umfasst eine metallhaltige Barriereschicht 12 aus 7 µm dickem Aluminium, eine polymere Schicht aus 12 µm dickem Polyethylenterephthalat (PET) und eine metallhaltige Dünnschicht aus 10 nm dickem Aluminium. Polyethylenterephthalat ist besonders geeignet, um die 7 µm dicke Aluminiumschicht vor mechanischer Beschädigung zu schützen, da PET-Folien sich durch eine besonders hohe Reißfestigkeit auszeichnen. Die Folienschichten sind so angeordnet, dass die Aluminiumschichten, das heißt die metallhaltige Barriereschicht 12 und die metallhaltige Dünnschicht 14, außen liegen. Die Folie wird auf einem erfindungsgemäßen polymeren Grundkörper so angeordnet, dass die metallhaltige Barriereschicht 12 zur Verklebungsfläche 5 zeigt. Dann zeigt die metallhaltige Dünnschicht 14 nach außen und wirkt zugleich als Haftschicht gegenüber dem Material der äußeren Versiegelungsschicht 17. So erfüllt die metallhaltige Dünnschicht 14 nicht nur eine Barrierewirkung sondern auch die Aufgabe eines Haftvermittlers. Durch geschickte Anordnung eines einfach herzustellenden Folienaufbaus kann somit ein effektiver Abstandhalter erhalten werden.
Der Aufbau der erfindungsgemäßen Isolationsfolie 10 senkt die Wärmeleitfähigkeit der Isolationsfolie im Vergleich zu den Isolationsfolien, die ausschließlich aus einer Aluminiumfolie bestehen, da die Dicken der metallhaltigen Schichten der erfindungsgemäßen Isolationsfolie 10 geringer sind. Isolationsfolien, die nur aus einer Aluminiumfolie bestehen müssen dicker sein, da Aluminiumfolien mit Dicken unter 0,1 mm hochempfindlich sind gegenüber mechanischen Beschädigungen, die zum Beispiel während des automatisierten Einbaus in eine Isolierverglasung auftreten können. Ein mit der genannten erfindungs-gemäßen Isolationsfolie 10 und dem glasfaserverstärkten polymeren Grundkörper 2 versehener Abstandshalter 1 weist eine thermische Wärmeleitfähigkeit von 0,29 W/(m K) auf. Ein Abstandshalter nach dem Stand der Technik, bei dem die erfindungsgemäße Isolationsfolie 10 durch eine 30 µm dicke Aluminiumschicht ersetzt ist, weist eine thermische Wärmeleitfähigkeit von 0,63 W/(m K) auf. Dieser Vergleich zeigt, dass mit dem erfindungsgemäßen Aufbau des Abstandshalters aus polymerem Grundkörper und Isolationsfolie trotz insgesamt geringerem Metallgehalt eine höhere mechanische Beständigkeit und eine gleichwertige Dichtigkeit (gegenüber Gas- und Feuchtigkeits-diffusion) bei gleichzeitig niedrigerer Wärmeleitfähigkeit erzielt werden kann, was deutlich die Effizienz einer Isolierverglasung erhöht. figure 3 shows a cross section of the insulating film 10 according to the invention. The insulating film 10 comprises a metal-containing barrier layer 12 made of 7 μm thick aluminum, a polymeric layer made of 12 μm thick polyethylene terephthalate (PET) and a metal-containing thin layer made of 10 nm thick aluminum. Polyethylene terephthalate is particularly suitable for protecting the 7 µm thick aluminum layer from mechanical damage, since PET films are particularly tear-resistant. The foil layers are arranged in such a way that the aluminum layers, ie the metal-containing barrier layer 12 and the metal-containing thin layer 14, are on the outside. The film is arranged on a polymer base body according to the invention in such a way that the metal-containing barrier layer 12 faces the bonding surface 5 . The metal-containing thin layer 14 then points outwards and at the same time acts as an adhesive layer with respect to the material of the outer sealing layer 17. The metal-containing thin layer 14 not only fulfills a barrier effect but also the task of an adhesion promoter. An effective spacer can thus be obtained by skilful arrangement of a film structure that is easy to produce.
The structure of the insulating film 10 according to the invention lowers the thermal conductivity of the insulating film in comparison to the insulating films which consist exclusively of an aluminum foil, since the thicknesses of the metal-containing layers of the insulating film 10 according to the invention are smaller. Insulation foils that only consist of an aluminum foil must be thicker, since aluminum foils with a thickness of less than 0.1 mm are highly sensitive to mechanical damage, which can occur, for example, during automated installation in insulating glazing. A spacer 1 provided with the mentioned insulating film 10 according to the invention and the glass fiber reinforced polymer base body 2 has a thermal conductivity of 0.29 W/(m K). A spacer according to the prior art, in which the insulating film 10 according to the invention is replaced by a 30 μm thick aluminum layer, has a thermal conductivity of 0.63 W/(m K). This comparison shows that with the structure of the spacer according to the invention polymer base body and insulating film, despite the overall lower metal content, higher mechanical resistance and equivalent tightness (compared to gas and moisture diffusion) can be achieved with lower thermal conductivity at the same time, which significantly increases the efficiency of insulating glazing.

Figur 4 zeigt einen Querschnitt einer alternativen Ausführungsform der erfindungsgemäßen Isolationsfolie. Die Materialien und Dicken sind wie in Figur 3 beschrieben, allerdings unterscheidet sich die Reihenfolge der einzelnen Schichten. Die metallhaltige Dünnschicht 14 liegt zwischen der metallhaltigen Barriereschicht 12 und der polymeren Schicht 13. In dieser Anordnung wird die metallhaltige Barriereschicht 12 durch die polymere Schicht 13 vor Beschädigung geschützt, wodurch eine uneingeschränkte Barrierewirkung sichergestellt wird. figure 4 shows a cross section of an alternative embodiment of the insulating film according to the invention. The materials and thicknesses are as in figure 3 described, but the order of the individual layers differs. The metal-containing thin layer 14 is sandwiched between the metal-containing barrier layer 12 and the polymeric layer 13. In this arrangement, the metal-containing barrier layer 12 is protected from damage by the polymeric layer 13, thereby ensuring an unrestricted barrier effect.

Figur 5 zeigt einen Querschnitt einer weiteren Ausführungsform der erfindungsgemäßen Isolationsfolie. Der Aufbau der Isolationsfolie 10 ist im Wesentlichen wie in Figur 4 beschrieben. Zusätzlich ist angrenzend an die polymere Schicht 13 eine weitere metallhaltige Dünnschicht 14 angeordnet. Diese Dünnschicht 14 verbessert insbesondere die Haftung zum Material der äußeren Versiegelungsschicht 17 in der fertigen Isolierverglasung. figure 5 shows a cross section of a further embodiment of the insulating film according to the invention. The structure of the insulating film 10 is essentially as in figure 4 described. In addition, a further metal-containing thin layer 14 is arranged adjacent to the polymeric layer 13 . This thin layer 14 improves in particular the adhesion to the material of the outer sealing layer 17 in the finished insulating glazing.

Figur 6 zeigt einen Querschnitt eines erfindungsgemäßen Abstandhalters umfassend einen glasfaserverstärkten polymeren Grundkörper 2 und eine Isolationsfolie 10, die auf der Verklebungsfläche 5, den Verbindungsflächen 6.1. und 6.2 sowie auf etwa zwei Dritteln der Scheibenkontakflächen 3.1 und 3.2 angebracht ist. Die Breite b des polymeren Grundkörpers entlang der Vergasungsinnenraumfläche 4 beträgt 12 mm und die Gesamthöhe g des polymeren Grundkörpers 2 beträgt 6,5 mm. Der Aufbau der Isolationsfolie 10 ist wie in Figur 3 gezeigt. Die Isolationsfolie 10 ist über einen Kleber 11, in diesem Fall ein Polyurethan-Schmelzkleber angebracht. Der Polyurethan-Schmelzkleber verklebt die zur Verklebungsfläche 5 weisende metallhaltige Barriereschicht 12 besonders gut mit dem polymeren Grundkörper 2. Es handelt sich bei dem Polyurethan-Schmelzkleber um einen nichtgasenden Klebestoff, um zu vermeiden, dass Gase in den Scheibeninnenraum 19 diffundieren und es dort zur Bildung von sichtbaren Niederschlägen kommt. figure 6 shows a cross section of a spacer according to the invention comprising a glass fiber reinforced polymer base body 2 and an insulating film 10, which is on the bonded surface 5, the connecting surfaces 6.1. and 6.2 as well as about two thirds of the disc contact surfaces 3.1 and 3.2. The width b of the polymer base body along the gasification interior surface 4 is 12 mm and the overall height g of the polymer base body 2 is 6.5 mm. The structure of the insulating film 10 is as in figure 3 shown. The insulating film 10 is attached via an adhesive 11, in this case a polyurethane hot-melt adhesive. The polyurethane hot-melt adhesive bonds the metal-containing barrier layer 12 pointing to the bonding surface 5 particularly well to the polymer base body 2. The polyurethane hot-melt adhesive is a non-gassing adhesive in order to prevent gases from diffusing into the interior of the pane 19 and from forming there comes from visible precipitation.
