Abstract

A car glass window pane is provided with a layer which is electrically conductive and reflects heat rays and, as such, has very low light transmission, of less than 20%, and, accordingly, a low surface resistance of less than 2 ohms per unit area. This layer is provided with regularly arranged interruptions (8), at least in a selected region, so that a grid-like layer structure is produced there. In consequence, the light transmission in this region is increased to at least approximately 40%, the low surface resistance at the same time being maintained or only slightly increased. <IMAGE>

Description

Die Erfindung betrifft eine Glasscheibe, insbesondere eine Autoglasscheibe, mit einer elektrisch leitenden und Waermestrahlen reflektierenden Schicht.The invention relates to a glass pane, in particular one Car window glass, with an electrically conductive and Layer reflecting heat rays.

Glasscheiben mit elektrisch leitender Oberflaechenbeschichtung sind in vielen Ausfuehrungen bekannt. Ein grundsaetzliches Problem bei allen bekannten Ausfuehrungen besteht darin, dass zur Erzielung eines niedrigen Flaechenwiderstands der Schicht die Schicht so dick sein muss, dass der Transmissionsgrad im Bereich des sichtbaren Lichts sehr niedrig ist und deshalb fuer manche Zwecke, beispielsweise fuer die Verwendung als elektrisch heizbare Autoglasscheiben, nicht ausreicht.Glass panes with electrically conductive Surface coatings are available in many designs known. A fundamental problem with all known ones Execution is that to achieve a low surface resistance of the layer must be thick that the transmittance in the range of visible light is very low and therefore for some Purposes, for example for use as electrical heatable car windows, not enough.

Man kann zwar auch elektrisch beheizbare Autoscheiben mit entsprechend hohem Transmissionsgrad, das heisst entsprechend duennen Leitschichten, realisieren, doch ist dann der Flaechenwiderstand so hoch, dass solche Heizscheiben nicht mit der im Kraftfahrzeug verfuegbaren Spannung von 12 Volt betrieben werden koennen, sondern eine wesentlich hoehere Spannung erfordern. Elektrische Spannungen bis 48 Volt sind zwar im Kraftfahrzeug zugelassen, doch erfordern solche erhoehten elektrischen Spannungen einen zusaetzlichen elektrischen Aufwand, der mit nicht unerheblichen Zusatzkosten verbunden ist.You can also use electrically heated car windows correspondingly high transmittance, that is correspondingly thin guide layers, but it is then the surface resistance so high that such Heating discs not with the one available in the motor vehicle Voltage of 12 volts can be operated, but one require much higher voltage. Electrical Voltages up to 48 volts are in the motor vehicle approved, but require such increased electrical Voltages an additional electrical effort that is associated with not inconsiderable additional costs.

Es ist auch bekannt und ueblich, elektrisch beheizbare Autoglasscheiben mit einer niedrigen Betriebsspannung in der Weise herzustellen, dass auf einer Oberflaeche der Glasscheibe schmale Heizleiter insbesondere aus einer Metallpartikel enthaltenden Einbrennpaste bzw. Email angeordnet und eingebrannt sind. Derartige Heizscheiben koennen aber nicht die Funktion von Sonnenschutzglaesern wahrnehmen, wie sie von Heizscheiben mit durchgehenden Oberflaechenschichten erfuellt werden.It is also known and customary to be electrically heated Car windows with a low operating voltage in the way that on a surface of the Glass pane narrow heating conductor in particular from a Burning paste or enamel containing metal particles are arranged and branded. Such heating discs but cannot do the function of sun protection glasses perceive them as being continuous from heating discs Surface layers are fulfilled.

Der Erfindung liegt die Aufgabe zugrunde, eine mit einer elektrisch leitenden und Waermestrahlen reflektierenden Schicht versehene Glasscheibe, insbesondere fuer den Einsatz in einem Kraftfahrzeug, zu schaffen, die einerseits aufgrund ihrer teilreflektierenden Eigenschaften zu einer wesentlichen Verringerung der eingestrahlten Waermeenergie fuehrt, und die andererseits gleichzeitig zumindest bereichsweise einen den Vorschriften entsprechenden Transmissionsgrad und einen hinreichend niedrigen Flaechenwiderstand aufweist, um mit den im Kraftfahrzeug ueblichen und zulaessigen elektrischen Spannungen betrieben werden zu koennen.The invention has for its object one with electrically conductive and reflecting heat rays Layered glass pane, especially for the Use in a motor vehicle to create the on the one hand due to their partially reflective properties to a substantial reduction in the irradiated Heat energy leads, and the other hand at the same time at least in some areas according to the regulations appropriate transmittance and a sufficient has low surface resistance in order to match the Motor vehicle usual and permitted electrical Voltages can be operated.

Ausgehend von einer mit einer IR-Strahlen reflektierenden elektrisch leitenden Oberflaechenschicht versehenen Glasscheibe wird die genannte Aufgabe erfindungsgemaess dadurch geloest, dass die elektrisch leitende und Waermestrahlen reflektierende Schicht einen niedrigen Flaechenwiderstand von weniger als 2 Ohm/Quadrateinheit und eine geringe Lichttransmission von weniger als 20% aufweist, und dass diese Schicht wenigstens in einem ausgewaehlten Bereich mit regelmaessigen Unterbrechungen versehen ist derart, dass unter Bildung einer rasterartigen oder streifenartigen Struktur die Lichttransmission in diesem Bereich auf wenigstens etwa 40% erhoeht wird, waehrend gleichzeitig der niedrige Flaechenwiderstand beibehalten bzw. nicht unzulaessig erhoeht wird.Starting from a reflective with an IR rays provided electrically conductive surface layer Glass pane is the object of the invention solved that the electrically conductive and Layer reflecting heat rays a low Area resistance less than 2 ohms / square unit and low light transmission of less than 20% and that this layer at least in one selected area with regular breaks is provided in such a way that to form a grid-like or stripe-like structure the light transmission in this area is increased to at least about 40%, while at the same time the low surface resistance maintained or not increased inadmissibly.

Durch die Erfindung wird also in gezielter Weise die Transmission der Glasscheibe durch die bereichsweise vollstaendige Entfernung der Leitschicht erhoeht, waehrend die verbleibenden Bereiche der Leitschicht die fuer die gesamte Heizleistung erforderliche Leitfaehigkeit beibehalten. Durch die Ausbildung der Leitschicht als regelmaessiges Raster wird gleichzeitig erreicht, dass auch in diesem ausgewaehlten Bereich die Waermeschutzwirkung der Glasscheibe in ausreichendem Masse erhalten bleibt.The invention thus in a targeted manner Transmission of the glass pane through the areas complete removal of the conductive layer increases while the remaining areas of the conductive layer are those for the total heating power required conductivity maintained. By forming the leading layer as  regular grid is achieved at the same time that too in this selected area the thermal protection effect of the A sufficient amount of glass is preserved.

Der Aufbau von elektrisch leitenden und IR-reflektierenden Schichten, insbesondere von Mehrfachschichten, sowie Verfahren zum Aufbringen solcher Mehrfachschichten, sind als solche bekannt und nicht Gegenstand der Erfindung.The construction of electrically conductive and IR reflective Layers, especially of multiple layers, as well Methods for applying such multiple layers are Known as such and not the subject of the invention.

Die Erfindung laesst sich beispielsweise realisieren bei duennen Leitschichten, die nach einem Vakuumverfahren aufgebracht sind, insbesondere nach dem Verfahren der Kathodenzerstaeubung, wobei fuer die metallische Leitschicht insbesondere Silber verwendet wird. Wenn aufgestaeubte Silberschichten bei einer Gleichspannung von 12 Volt eine Heizleistung von 3 bis 5 Watt/dm2 aufweisen sollen, muss die Dicke der metallischen Leitschicht etwa 0,5 bis 1 Mikrometer betragen. Bei dieser Schichtdicke betraegt aber die Transmission im Bereich des sichtbaren Lichts allenfalls noch einige Prozent. Durch geeignete Rasterausbildung der Silberschicht in der Weise, dass in dem ausgewaehlten Sichtfeld beispielsweise etwa 40% der Flaeche der Silberschicht in Rasterform nachtraeglich entfernt werden, oder stattdessen beim Aufbringen der Silberschicht durch eine entsprechende rasterfoermige Abdeckung der Glasscheibe fuer einen rasterfoermigen Niederschlag der Silberschicht gesorgt wird, laesst sich die Transmission auf einen dem Anteil der nicht beschichteten Flaeche entsprechenden Transmissionsgrad erhoehen. Gleichzeitig bleibt die elektrische Leitfaehigkeit auf einem Wert, wie er fuer die gewuenschte Heizleistung erforderlich ist. The invention can be implemented, for example, in the case of thin conductive layers which are applied by a vacuum process, in particular by the cathode sputtering process, silver being used in particular for the metallic conductive layer. If dusty silver layers are to have a heating power of 3 to 5 watts / dm 2 at a DC voltage of 12 volts, the thickness of the metallic conductive layer must be about 0.5 to 1 micrometer. At this layer thickness, the transmission in the visible light range is at most a few percent. By means of a suitable grid formation of the silver layer in such a way that, for example, about 40% of the surface of the silver layer in grid form is subsequently removed in the selected field of view, or instead, when the silver layer is applied, a grid-shaped covering of the glass pane is provided for a grid-shaped precipitation of the silver layer, the transmission can be increased to a degree of transmission corresponding to the proportion of the uncoated surface. At the same time, the electrical conductivity remains at a level that is required for the desired heating output.

Um eine rasterfoermige Schicht bereits als solche auf die Glasscheibe aufzubringen, kann man beispielsweise beim Aufstaeuben der Schicht die von der Schicht freizuhaltenden Teile der Glasoberflaeche abdecken, und zwar entweder durch eine geeignete Rasterblende, die zwischen der Beschichtungskathode und der Glasoberflaeche angeordnet wird, oder durch eine entsprechende Rasterfolie, die auf die Glasscheibe aufgebracht und nach dem Aufstaeuben der Leitschicht entfernt wird.For a grid-like layer as such on the Applying glass, you can for example at Dusting the layer to be kept free of the layer Cover parts of the glass surface, either through a suitable grid aperture that between the Coating cathode and the glass surface arranged is, or by an appropriate grid film that is on applied the glass and after dusting the Conductive layer is removed.

Eine andere Moeglichkeit zur Realisierung solcher Raster besteht, wie bereits erwaehnt, darin, zunaechst eine gleichmaessige durchgehende Schicht aufzubringen und Teile der Schicht spaeter wieder zu entfernen. Die teilweise Entfernung der Schicht kann auf chemischem Wege, beispielsweise durch ein geeignetes Aetzverfahren, oder auch auf mechanischem Wege, beispielsweise mit Hilfe eines Laserstrahls, erfolgen.Another possibility for realizing such grids consists, as already mentioned, of first one apply even, continuous layer and parts to remove the layer later. The partially Removal of the layer can be done chemically, for example by a suitable etching process, or also mechanically, for example with the help of a Laser beam.

Ein Ausfuehrungsbeispiel der Erfindung wird anhand der Fig. 1, die eine Ansicht einer erfindungsgemaess ausgebildeten Autorueckwandscheibe darstellt, naeher beschrieben.An exemplary embodiment of the invention is described in more detail with reference to FIG. 1, which represents a view of a car rear window pane designed according to the invention.

Bei der Autoglasscheibe 1 kann es sich um eine monolythische Glasscheibe, das heisst um eine Einscheibensicherheitsglasscheibe, oder um eine mehrschichtige Glasscheibe, das heisst eine Verbundsicherheitsglasscheibe handeln. Die elektrisch leitende und IR-reflektierende Schicht ist im Fall einer Einscheibensicherheitsglasscheibe auf der dem Fahrgastraum zugewandten Oberflaeche der Glasscheibe angeordnet. Im Fall einer Verbundsicherheitsglasscheibe ist die Schicht im Innern der Verbundglasscheibe, das heisst auf einer an der thermoplastischen Zwischenschicht anliegenden Oberflaeche einer der die Verbundglasscheibe bildenden Einzelglasscheiben angeordnet.The car glass pane 1 can be a monolithic glass pane, that is to say a single-pane safety glass pane, or a multilayer glass pane, that is to say a laminated safety glass pane. In the case of a single-pane safety glass pane, the electrically conductive and IR-reflecting layer is arranged on the surface of the glass pane facing the passenger compartment. In the case of a laminated safety glass pane, the layer is arranged in the interior of the laminated glass pane, that is to say on one of the individual glass panes forming the laminated glass pane on a surface lying against the thermoplastic intermediate layer.

Die elektrisch leitende IR-reflektierende Schicht ist in verschiedene Felder aufgeteilt. Durch zwei schmale kanalartige Unterbrechungen 2 und 3, die parallel zur oberen Kante der Glasscheibe bzw. zu deren unterer Kante verlaufen, sind im oberen Bereich der Glasscheibe ein streifenfoermiger Bereich 4, und im unteren Bereich der Glasscheibe ein streifenfoermiger Bereich 5 gebildet. Diese Bereiche stehen infolge der Unterbrechungen 2 und 3 nicht mehr in leitender Verbindung mit dem Mittelfeld der Leitschicht.The electrically conductive IR-reflecting layer is divided into different fields. A strip-shaped area 4 is formed in the upper area of the glass sheet and a strip-shaped area 5 is formed in the upper area of the glass sheet by two narrow channel-like interruptions 2 and 3 , which run parallel to the upper edge of the glass sheet or to its lower edge. As a result of the interruptions 2 and 3, these areas are no longer in conductive connection with the central field of the conductive layer.

Im Mittelfeld besteht die Leitschicht jeweils entlang den beiden Seitenkanten aus streifenfoermigen Feldern 6 und 7, in denen die Leitschicht als kontinuierliche Schicht vorliegt. Zwischen diesen streifenfoermigen seitlichen Feldern 6, 7 ist die Schicht rasterartig ausgebildet. Die streifenfoermigen Felder 6, 7 dienen gleichzeitig als Sammelschienen fuer die Stromzufuehrung zu der rasterartigen Schichtstruktur zwischen diesen Feldern. Das Raster ist dadurch gebildet, dass in der Schicht eine Vielzahl von regelmaessig angeordneten kleinen Feldern 8 bestehen, die im dargestellten Fall als kleine Quadrate ausgebildet sind, in denen die elektrisch leitende reflektierende Schicht entfernt ist. Es bleiben von der elektrisch Leitenden reflektierenden Schicht infolgedessen nur schmale sich kreuzende Streifen 9 erhalten, die ein elektrisch leitendes Netzwerk bilden. Das Flaechenverhaeltnis der unbeschichteten Quadrate 8 zu den elektrisch leitenden Streifen 9 betraegt in diesem rasterartigen Mittelfeld etwa 4:6, so dass der Transmissionsgrad in diesem Mittelfeld infolgedessen wenigstens etwa 40% betraegt.In the middle field, the guiding layer consists in each case along the two side edges of strip-shaped fields 6 and 7 in which the guiding layer is present as a continuous layer. The layer is formed in a grid-like manner between these strip-shaped lateral fields 6 , 7 . The strip-shaped fields 6 , 7 also serve as busbars for the current supply to the grid-like layer structure between these fields. The grid is formed in that there are a multiplicity of regularly arranged small fields 8 in the layer, which in the case shown are designed as small squares in which the electrically conductive reflective layer is removed. As a result, only narrow intersecting strips 9 remain of the electrically conductive reflective layer, which form an electrically conductive network. The area ratio of the uncoated squares 8 to the electrically conductive strips 9 is approximately 4: 6 in this grid-like central field, so that the transmittance in this central field is consequently at least approximately 40%.
