Description
Die Erfindung betrifft eine Verbundscheibe.The invention relates to a composite pane.

Die
Verglasungen wie sie in Sonnendächern und Schiebedächern eingesetzt werden, erfordern bekannterweise eine Lichttransmission zwischen 2 % und 10 % und einen spezifischen Sonnenschutz, charakterisiert durch den TTS-Wert, der ein Maß für die totale transmittierte Wärmestrahlung der Sonne durch die Scheibe darstellt, und beispielsweise gemäß der ISO 9050 gemessen wird. Bei einer höheren Lichttransmission wird zum einen zu viel Wärmestrahlung transmittiert und zum anderen können die Personen hinter der Verglasung durch zu viel Lichteintrag visuell gestört sein. Bei einer niedrigeren Lichttransmission ist die Verglasung insgesamt zu dunkel, sodass die Personen hinter der Verglasung nicht mehr durch diese hindurchsehen können.Glazing as used in sunroofs and sunroofs is known to require light transmission of between 2% and 10% and specific sun protection, characterized by the TTS value, which is a measure of the total thermal radiation transmitted by the sun through the pane, and for example according to the ISO 9050 is measured. With a higher light transmission, too much thermal radiation is transmitted on the one hand and on the other hand the people behind the glazing can be visually disturbed by too much light entering. If the light transmission is lower, the glazing is too dark overall so that the people behind the glazing can no longer see through it.

where TL is the light transmittance and TE is the energy transmittance, each measured according to ISO 9050.
Es sind auch Windschutzscheiben bekannt, beispielsweise durch die
Elektrisch regelbare Sonnenblenden finden darüber hinaus auch Anwendung in Glasdächern von Kraftfahrzeugen. Insbesondere bei großflächigen Panoramaglasscheiben besteht das Bedürfnis, die Transmission der Scheibe variabel zu steuern. Je nach Sonnenstand besteht dabei die Notwendigkeit lediglich Teilbereiche der Scheibe abzublenden, oder auch als Blickschutz im geparkten Fahrzeug die vollständige Fläche intransparent zu schalten.Electrically controllable sun visors are also used in glass roofs of motor vehicles. Particularly in the case of large-area panoramic glass panes, there is a need to variably control the transmission of the pane. Depending on the position of the sun, it is only necessary to shade off partial areas of the pane, or to switch the entire surface opaque as privacy protection in the parked vehicle.
Ein solches mögliches elektrisch schaltbares Funktionselement zur Realisierung von regelbaren Sonnenblenden ist ein sogenanntes PDLC-Funktionselement (polymer dispersed liquid crystal). Die aktive Schicht enthält dabei Flüssigkristalle, welche in eine Polymermatrix eingelagert sind. Wird keine Spannung angelegt, so sind die Flüssigkristalle ungeordnet ausgerichtet, was zu einer starken Streuung des durch die aktive Schicht tretenden Lichts führt. Wird an die Flächenelektroden eine Spannung angelegt, so richten sich die Flüssigkristalle in einer gemeinsamen Richtung aus und die Transmission von Licht durch die aktive Schicht wird erhöht. Das PDLC-Funktionselement wirkt weniger durch Herabsetzung der Gesamttransmission, sondern durch Erhöhung der Streuung, um den Blendschutz zu gewährleisten.Such a possible electrically switchable functional element for the realization of controllable sun visors is a so-called PDLC (polymer dispersed liquid crystal) functional element. The active layer contains liquid crystals embedded in a polymer matrix. If no voltage is applied, the liquid crystals are aligned in a disorderly manner, which leads to strong scattering of the light passing through the active layer. If a voltage is applied to the surface electrodes, the liquid crystals align in a common direction and the transmission of light through the active layer is increased. The PDLC functional element works less by lowering the overall transmission, but by increasing the spread to ensure anti-glare protection.
Windschutzscheiben mit elektrisch regelbaren Sonnenblenden sind beispielsweise bekannt aus
Aus der
Die elektrische Kontaktierung von elektrisch steuerbaren Funktionselementen erfolgt üblicherweise über Sammelleiter (auch als „bus bars“ bezeichnet), die im Randbereich des Funktionselementes auf die Flächenelektroden aufgebracht sind und diese elektrisch leitend kontaktieren. Durch Verbinden der Sammelleiter mit einer externen Spannungsquelle, beispielsweise über an den Sammelleitern angebrachte Flachleiter, wird eine Spannung an den Flächenelektroden angelegt und die aktive Schicht des Funktionselementes geschaltet.The electrical contacting of electrically controllable functional elements usually takes place via bus bars, which are applied to the surface electrodes in the edge area of the functional element and contact them in an electrically conductive manner. By connecting the bus bars to an external voltage source, for example via flat conductors attached to the bus bars, a voltage is applied to the surface electrodes and the active layer of the functional element is switched.
Aufgabe der Erfindung ist es eine Verbundscheibe mit einem verdunkelten Bereich anzugeben, welche mit zumindest einer der vorgenannten Beschichtungen oder Funktionalitäten kompatibel ist. Weitere Aufgabe der Erfindung ist es ein kostengünstiges, variabel einsetzbares Herstellungsverfahren anzugeben.The object of the invention is to specify a laminated pane with a darkened area which is compatible with at least one of the aforementioned coatings or functionalities. A further object of the invention is to specify a cost-effective manufacturing method that can be used in a variety of ways.
Die erfindungsgemäße Verbundscheibe umfasst eine erste Scheibe mit einer außenseitigen Oberfläche und einer innenseitigen Oberfläche, eine zweite Scheibe mit einer außenseitigen Oberfläche und einer innenseitigen Oberfläche und eine Zwischenschicht, welche insbesondere eine Funktionsschicht ist, welche zwischen der innenseitige Oberfläche der erste Scheibe mit der außenseitigen Oberfläche der zweite Scheibe angeordnet ist, wobei die zweite Scheibe als Innenscheibe ausgelegt ist, wobei die erste Scheibe als Außenscheibe ausgelegt ist. Unter Außenseite ist die Seite der ersten Scheibe bzw. Außenscheibe zu verstehen, während unter Innenseite die der zweiten Scheibe bzw. Innenscheibe zu verstehen ist. Bei einer Verwendung als Fahrzeugverglasung oder Gebäudeverglasung ist die Innenseite somit im Innenraum des Fahrzeugs bzw. Gebäudes.The laminated pane according to the invention comprises a first pane with an outside surface and an inside surface, a second pane with an outside surface and an inside surface, and an intermediate layer, which is in particular a functional layer that lies between the inside surface of the first pane and the outside surface of the second pane is arranged, wherein the second pane is designed as an inner pane, wherein the first pane is designed as an outer pane. The outside is to be understood as meaning the side of the first pane or outer pane, while the inside is to be understood as meaning that of the second pane or inner pane. When used as vehicle glazing or building glazing, the inside is therefore in the interior of the vehicle or building.
Weiterhin umfasst die Verbundscheibe eine erste Polymerfolie und eine zweite Polymerfolie, wobei die erste Polymerfolie zwischen der innenseitigen Oberfläche der ersten Scheibe und der Zwischenschicht angeordnet ist und die zweite Polymerfolie zwischen der außenseitigen Oberfläche der zweiten Scheibe und der Zwischenschicht angeordnet ist.Furthermore, the laminated pane comprises a first polymeric film and a second polymeric film, wherein the first polymeric film is disposed between the inside surface of the first pane and the intermediate layer and the second polymeric film is disposed between the outside surface of the second pane and the intermediate layer.
Auf die erste Polymerfolie und/oder zweite Polymerfolie ist eine gedruckte opake Schicht in einem Randbereich der Verbundscheibe aufgebracht.A printed opaque layer is applied to the first polymer film and/or second polymer film in an edge region of the laminated pane.
Bei der auf die Polymerfolie gedruckten opaken Schicht handelt es sich insbesondere um eine undurchsichtige Emailleersatzschicht, welche mittels eines Druckverfahrens aufgetragen ist. Die opake Schicht ist insbesondere schwarz und kann einen Emaillelack umfassen.The opaque layer printed on the polymer film is in particular an opaque enamel substitute layer which is applied by means of a printing process. The opaque layer is in particular black and can comprise an enamel paint.
Der Vorteil des Auftragens auf die erste und/oder zweite Polymerfolie besteht darin, dass eine kostengünstigere Herstellung möglich ist. Weiterhin ist auch eine Kombination mit beschichteten Gläsern möglich.The advantage of applying it to the first and/or second polymer film is that it can be produced more cost-effectively. A combination with coated glasses is also possible.
In Ausgestaltung ist auf der ersten Polymerfolie eine gedruckte erste opake Schicht auf einer zur Zwischenschicht gerichteten Oberfläche oder zur innenseitigen Oberfläche der ersten Scheibe hin ausgerichteten Oberfläche aufgebracht.In one embodiment, a printed first opaque layer is applied to the first polymer film on a surface oriented toward the intermediate layer or on a surface oriented toward the inside surface of the first pane.
In einer alternativen Ausgestaltung ist eine erste gedruckte opake Schicht auf einer innenseitigen Oberfläche der ersten Scheibe aufgebracht. In diesem Fall ist die gedruckte opake Schicht insbesondere eine Emaille-Schicht, welche nach dem Druckvorgang noch gebrannt ist.In an alternative embodiment, a first printed opaque layer is applied to an inside surface of the first pane. In this case, the printed opaque layer is in particular an enamel layer which is still fired after the printing process.
Die erste opake Schicht bildet zweckmäßigerweise und daher bevorzugt einen umlaufenden Rand der Verbundscheibe. Optional kann die erste opake Schicht einen oder mehrere zur Mitte der Verbundscheibe versetzte Streifen oder Muster aufweisen.The first opaque layer expediently and therefore preferably forms a peripheral edge of the laminated pane. Optionally, the first opaque layer can have one or more towards the middle of Ver staggered stripes or patterns.
In einer weiteren Ausgestaltung ist auf der zweiten Polymerfolie eine gedruckte zweite opake Schicht auf einer zur Zwischenschicht gerichteten Oberfläche oder zur außenseitigen Oberfläche der zweiten Scheibe hin ausgerichteten Oberfläche aufgebracht.In a further embodiment, a printed second opaque layer is applied to the second polymer film on a surface oriented towards the intermediate layer or on a surface oriented towards the outside surface of the second pane.
Die zweite opake Schicht bildet zweckmäßigerweise und daher bevorzugt einen umlaufenden Rand der Verbundscheibe. Optional kann die zweite opake Schicht einen oder mehrere zur Mitte der Verbundscheibe versetzte Streifen oder Muster aufweisen.The second opaque layer expediently and therefore preferably forms a peripheral edge of the laminated pane. Optionally, the second opaque layer may have one or more stripes or patterns offset toward the center of the composite pane.
Die erste opake Schicht und/oder zweite opake Schicht bedecken zumindest den Randbereich bedecken, in dem elektrische Anschlüsse der als Funktionsschicht ausgebildeten Zwischenschicht angeordnet sind.The first opaque layer and/or second opaque layer cover at least the edge region in which electrical connections of the intermediate layer designed as a functional layer are arranged.
Die als Funktionsschicht ausgebildete Zwischenschicht umfasst zweckmäßigerweise und daher bevorzugt eine Flüssigkristallschicht, insbesondere PDLC-Schicht, oder eine OLED-Schicht, welche zumindest entlang einer Seitenkante, insbesondere zwei gegenüberliegenden Seitenkanten, mit mindestens einem Sammelleiter verbunden ist. Eine Kontaktierung an zwei gegenüberliegenden Seitenkanten ist z.B. bei einer rechteckigen aber auch trapezförmigen Flächenform der Funktionsschicht möglich. Der Sammelleiter dient zur elektrischen Kontaktierung der Funktionsschicht.The intermediate layer designed as a functional layer expediently and therefore preferably comprises a liquid crystal layer, in particular a PDLC layer, or an OLED layer, which is connected to at least one bus bar at least along one side edge, in particular two opposite side edges. Contacting on two opposite side edges is possible, for example, with a rectangular but also trapezoidal surface shape of the functional layer. The bus bar is used for electrical contacting of the functional layer.
Die Funktionsschicht umfasst zweckmäßigerweise und daher bevorzugt weiterhin eine erste und zweite Dichtschicht umfasst. Eine solche Dichtschicht ist insbesondere aus einer Polymerfolie, insbesondere einer thermoplastischen Polymerfolie, beispielsweise Polyethylenterephthalat (PET), gebildet.The functional layer expediently and therefore preferably also comprises a first and second sealing layer. Such a sealing layer is formed in particular from a polymer film, in particular a thermoplastic polymer film, for example polyethylene terephthalate (PET).
Angrenzend an die Zwischenschicht ist in Ausgestaltung eine dritte und/oder vierte Polymerfolie angeordnet, welche zumindest in einem Teil des Randbereiches angeordnet ist. Die dritte und/oder vierte Polymerfolie ist insbesondere aus einer thermoplastischen Polymerfolie, beispielsweise PET, gebildet.In one embodiment, a third and/or fourth polymer film is arranged adjacent to the intermediate layer, which is arranged at least in part of the edge region. The third and/or fourth polymer film is formed in particular from a thermoplastic polymer film, for example PET.
In einer weiteren Ausgestaltung ist zwischen der ersten Scheibe und der Zwischenschicht eine weitere Polymerfolie oder Polymerzwischenschicht angeordnet.In a further configuration, a further polymer film or polymer intermediate layer is arranged between the first pane and the intermediate layer.
Die Verbundscheibe umfasst zweckmäßigerweise und daher bevorzugt einen Dickenausgleich. Ein solcher Dickenausgleich ist dazu ausgelegt, die Dicke der Funktionsschicht und der elektrischen Anschlüsse, insbesondere der Sammelleiter, auszugleichen.The laminated pane expediently and therefore preferably comprises a thickness equalizer. Such a thickness compensation is designed to compensate for the thickness of the functional layer and the electrical connections, in particular the bus bars.
In einer weiteren Ausgestaltung enthält die erste Polymerfolie und/oder zweite Polymerfolie und/oder weitere Polymerfolie Polyvinylbutyral, Ethylenvinylacetat, Polyurethan und/oder Gemische davon und/oder Copolymere oder ist Polyvinylbutyral (PVB).In a further configuration, the first polymer film and/or second polymer film and/or further polymer film contains polyvinyl butyral, ethylene vinyl acetate, polyurethane and/or mixtures thereof and/or copolymers or is polyvinyl butyral (PVB).
In einer weiteren Ausgestaltung ist die erste Scheibe und/oder zweite Scheibe eine getönte oder klare Glasscheibe oder Kunststoffscheibe, welche insbesondere mit einer Wärmestrahlen reflektierenden Beschichtung versehen ist.In a further embodiment, the first pane and/or second pane is a tinted or clear glass pane or plastic pane, which is provided in particular with a coating that reflects heat rays.
Solche Beschichtungen sind beispielsweise aus der
Die Wärmestrahlen reflektierende Beschichtung umfasst bevorzugt eine funktionelle Schicht, welche ein transparentes leitfähiges Oxid (TCO), enthält, bevorzugt Indiumzinnoxid, mit Antimon oder Fluor dotiertes Zinnoxid und/oder mit Gallium und/oder Aluminium dotiertem Zinkoxid (ZnO: Ga, bzw. ZnO: AI), wobei Indiumzinnoxid bevorzugt ist. Die die funktionelle Schicht kann aber auch andere, elektrisch leitfähige Oxide enthalten, beispielsweise Fluor-dotiertes Zinnoxid (SnO2:F), Antimon-dotiertes Zinnoxid (SnO2:Sb), Indium-Zink-Mischoxid (IZO), Gallium-dotiertes oder Aluminium-dotiertes Zinkoxid, Niobium-dotiertes Titanoxid, Cadmiumstannat und/oder Zinkstannat. Damit werden besonders gute Ergebnisse hinsichtlich der Emissivität und der Biegbarkeit der erfindungsgemäßen Beschichtung erreicht. Der Brechungsindex des Materials der funktionellen Schicht beträgt bevorzugt 1,7 bis 2,5.The thermal radiation-reflecting coating preferably comprises a functional layer which contains a transparent conductive oxide (TCO), preferably indium tin oxide, tin oxide doped with antimony or fluorine and/or zinc oxide doped with gallium and/or aluminum (ZnO: Ga, or ZnO: AI), with indium tin oxide being preferred. However, the functional layer can also contain other electrically conductive oxides, for example fluorine-doped tin oxide (SnO 2 :F), antimony-doped tin oxide (SnO 2 :Sb), indium-zinc mixed oxide (IZO), gallium-doped or Aluminum-doped zinc oxide, niobium-doped titanium oxide, cadmium stannate and/or zinc stannate. This achieves particularly good results with regard to the emissivity and the flexibility of the coating according to the invention. The refractive index of the material of the functional layer is preferably 1.7 to 2.5.
Die Wärmestrahlen reflektierende Beschichtung umfasst außerdem typischerweise dielektrische Schichten, insbesondere aus dielektrischen Oxiden oder Nitriden gebildet, wie ZnO, SnZnO, AlN, TiO2, SiO2 oder Si3N4. Die Schicht aus reflektierendem leitfähigen Oxid wird durch Verwendung zusätzlicher dielektrischer Schichten oberhalb und unterhalb entspiegelt, um eine ausreichend niedrige Reflexion von der Innenseite zu gewährleisten.The thermal ray reflective coating also typically includes dielectrics Layers, formed in particular from dielectric oxides or nitrides, such as ZnO, SnZnO, AlN, TiO 2 , SiO 2 or Si 3 N 4 . The layer of reflective conductive oxide is anti-reflective using additional dielectric layers above and below to ensure sufficiently low reflection from the inside.
Alternativ oder zusätzlich ist die erste Polymerfolie und/oder zweite Polymerfolie mit einer Polymerzwischenschicht versehen, welche insbesondere eine Wärmestrahlen reflektierenden Beschichtung ist oder enthält.As an alternative or in addition, the first polymer film and/or second polymer film is/are provided with a polymer intermediate layer, which in particular is or contains a coating that reflects heat rays.
Ein Verfahren zum Herstellen einer erfindungsgemäßen Verbundscheibe umfasst:
- - Bereitstellen einer ersten Scheibe und einer zweiten Scheibe und einer Zwischenschicht, insbesondere Funktionsschicht
- - Drucken einer ersten opake Schicht auf eine erste Polymerfolie oder Drucken einer ersten opake Schicht eine innenseitige Oberfläche der ersten Scheibe mit optionalem anschließendem Einbrennen, und/oder
- - Drucken einer zweiten opake Schicht auf eine zweite Polymerfolie,
- - Laminieren der ersten Scheibe mit der Funktionsschicht und der zweiten Scheibe, wobei zwischen der ersten Scheibe und der Funktionsschicht die erste Polymerfolie und zwischen der zweiten Scheibe und der Funktionsschicht die zweite Polymerfolie angeordnet ist.
- - Providing a first pane and a second pane and an intermediate layer, in particular a functional layer
