Description

Die Erfindung betrifft eine wärmeisolierende und schalldämmende Glaseinheit mit auf Abstand gehaltenen Glasscheiben und gegen die Atmosphäre abgedichteten Scheibenzwischenräumen, die als Füllgas eine Gasmischung mit Anteilen aus Fluor-Kohlenwasserstoffen oder Fluor-Chlor-Kohlenwasserstoffen enthalten.The invention relates to a heat-insulating and sound-absorbing glass unit with glass panes spaced apart and glass panes sealed against the atmosphere, which contain a gas mixture with fractions of fluorohydrocarbons or fluorochlorohydrocarbons as the filling gas.

Es ist bekannt, die Scheibenzwischenräume von geklebten oder gelöteten Isolierglaseinheiten mit trockener Luft zu füllen. Eine bessere Wärme- und (oder) Schalldämmung läßt sich mit Argon, Kohlendioxid, Helium, Dichlordifluormethan, Schwefelhexafluorid oder deren Mischungen erreichen.It is known to fill the inter-pane spaces of glued or soldered insulating glass units with dry air. Better heat and (or) sound insulation can be achieved with argon, carbon dioxide, helium, dichlorodifluoromethane, sulfur hexafluoride or mixtures thereof.

In der DE-.A-2 461 532 ist eine aus mehreren Scheiben zusammengesetzte Isolierglasscheibe mit bestimmtem Scheibendickenverhältnis beschrieben deren Scheibenzwischenräume zum Zweck der Schalldämmung mit Gasen gefüllt sind. Neben einer Vielzahl von Gasen sind relativ allgemein gehaltene Kriterien für geeignete Gasfüllungen angegeben, so Z.B., daß die Schallgeschwindigkeit des gases oder der Gasmischung etwa 10 ― 60% unter des von Luft liegt.DE-.A-2 461 532 describes an insulating glass pane composed of a plurality of panes with a specific pane thickness ratio, the panes of which are filled with gases for the purpose of sound insulation. In addition to a large number of gases, relatively general criteria for suitable gas fillings are given, for example that the speed of sound of the gas or the gas mixture is about 10-60% below that of air.

Durch die FR - A - 2 284 745 ist eine Gasfüllung bekannt, durch die die schalldämmende Wirkung einer Glaseinheit unterstützt werden soll. Dabei haben die Füllgase wie He, Ne, H2' SFe und F-CI-Kohlenwasserstoffe nur die Bedingung zu erfüllen, daß die Schallgeschwindigkeit von der der Luft verschieden sein soll.A gas filling is known from FR-A-2 284 745 which is intended to support the sound-absorbing effect of a glass unit. The filling gases such as He, Ne, H 2 ' SF e and F-CI hydrocarbons only have to meet the condition that the speed of sound should be different from that of the air.

Schließlich ist durch die BE - A - 628 413 die Verwendung eines Füllgases, dessen Molekulargewicht höher als Wasser bzw. Luft ist, für den Zwischenraum zwischen zwei Scheiben einer isolierenden Glaseinheit bekannt. Für das Füllgas werden Gase oder Gasgemische aus Fluor-Kohlenwasserstoffen oder Fluor-Chlor-Kohlenwasserstoffen CO2 und SFe angegeben.Finally, BE - A - 628 413 discloses the use of a filling gas, the molecular weight of which is higher than water or air, for the space between two panes of an insulating glass unit. Gases or gas mixtures of fluorocarbons or fluorochlorohydrocarbons CO 2 and SF e are specified for the filling gas.

In den beiden zuerst genannten Druckschriften sind Gasfüllungen angegeben, die nur schalldämmend wirken. Durch die zuletzt angegebene Druckschrift ist ein Verfahren bekannt, durch das Feuchtigkeit und Luft aus dem Scheibenzwischenraum einere Isolierglaseinheit verdrängt werden kann. Dieses Verfahren ist unabhängig von Größe und Bauform der Glaseinheit durchführbar. Die Schall- und Wärmedämmwerte sind jedoch von der Größe und Form der Glaseinheit abhängig.In the two publications mentioned first, gas fillings are specified which only have a sound-absorbing effect. The last-mentioned document discloses a method by which moisture and air from the space between the panes can be used to displace another insulating glass unit. This procedure can be carried out regardless of the size and design of the glass unit. However, the sound and thermal insulation values depend on the size and shape of the glass unit.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Isolierglaseinheit anzugeben, durch die für alle gängigen Größen und Formen von Glaseinheiten mit wenigstens einem Scheibenzwichenraum sowohl die schalldämmende als auch die wärmeisolierende Wirkung erhöht werden kann.The invention is therefore based on the object of specifying an insulating glass unit by means of which both the sound-absorbing and the heat-insulating effect can be increased for all common sizes and shapes of glass units with at least one pane intermediate space.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Füllgas aus einer der folgenden Gasmischungen besteht:

  • 1. C2F,CL2 + CF3CI im Verhältnis von 0 bis 20 Vol.-% zu 80 bis 100 Vol.-%;
  • 2. Neon + CF3CI im Verhältnis von 0 bis 30 Vol.-% zu 70 bis 100 Vol.-%;
  • 3a. C4F8 und ein anderer oder mehrere andere aliphatische Fluor-Chlor-Kohlenwasser-. stpffe und Neon im Verhältnis von 0 bis 30 Vol.- % zu 40 bis 60 Vol.-% zu 20 bis 30 Vol.-%;
  • 3b. C4Fs + Neon im Verhältnis von 20 bis 30 Vol.-% zu 70 bis 80 Vol.-%.
This object is achieved in that the filling gas consists of one of the following gas mixtures:
  • 1. C 2 F, CL 2 + CF 3 CI in a ratio of 0 to 20% by volume to 80 to 100% by volume;
  • 2. Neon + CF 3 CI in a ratio of 0 to 30% by volume to 70 to 100% by volume;
  • 3a. C 4 F 8 and another or more other aliphatic fluoro-chloro-hydro-. Stpffe and neon in a ratio of 0 to 30% by volume to 40 to 60% by volume to 20 to 30% by volume;
  • 3b. C 4 F s + neon in a ratio of 20 to 30% by volume to 70 to 80% by volume.

Mit den genannten Gasen bzw. deren Mischungen wird eine Verbesserung der Schall- dämmwerte und der Wärmedämmwerte gegenüber den bisherigen Scheibenfüllungen erreicht. Das einzige Gas, mit welchem nahezu ähnliche Schalldämmwerte erzielt werden, ist SFs. Dieses weist jedoch, wie alle Reingase, Resonanzeinbrücke der Schalldämmung im unteren Frequenzbereich auf. Die erfindungsgemäßen Gasgemisch hingegen führen bei sehr gutem Schall- und Wärmedämmverhalten auch im kritischen Frequenzbereich zu wesentlich verbessertem Dämmverhalten. Mit Variationen der Gemischzusammensetzungen lassen sich im Gegensatz zu Reingasfüllungen Verschiebungen der Resonanzfrequenzen erreichen. Damit ist eine Anpassung der Scheibenfüllungen an unterschiedliche Scheibenkonstruktionen möglich. Eine Anpassung der Gasfüllung an die Scheibenkonstruktion ist notwendig, denn durch Konstruktiönsmerkmale wie Scheibenabstand oder Masse wird die Resonanzfrequenz beeinflußt, bei der die Schalldämmung ein Minimum erreicht. Insbesondere mit den erfindungsgemäßen 'Gasgemisch ist eine Anpassung an verschiedene Isolierglaseinheiten unter dem Gesichtspunkt guter Dämmeigenschaften möglich.With the gases mentioned or their mixtures, an improvement in the sound insulation values and the thermal insulation values is achieved compared to the previous window fillings. The only gas with which almost similar sound insulation values can be achieved is SF s . However, like all clean gases, this has a resonance bridge in the sound insulation in the lower frequency range. In contrast, the gas mixtures according to the invention, with very good sound and heat insulation behavior, also lead to significantly improved insulation behavior even in the critical frequency range. In contrast to clean gas fillings, shifts in the resonance frequencies can be achieved with variations in the mixture compositions. This makes it possible to adapt the pane fillings to different pane constructions. An adjustment of the gas filling to the pane construction is necessary, because design features such as pane spacing or mass influence the resonance frequency at which the sound insulation reaches a minimum. In particular, with the gas mixture according to the invention, adaptation to different insulating glass units is possible from the point of view of good insulation properties.

Mit besonderem Vorteil werden als Scheibenfüllungen Gasmischungen verwendet, die die im Anspruch 2 genannten Zusammensetzungen haben. In den angegebenen Bereichen läßt sich die Gemischzusammensetzung an unterschiedliche Größen und Bauformen von Isolierglaseinheiten optimal anpassen, wodurch, wie beschrieben, gute Dämmwirkung auch bei niedrigen Frequenzen erreicht wird. Mit den angegebenen Gasmischungen können daher alle handelsüblichen Isolierglaseinheiten gefüllt werden, wobei für die Dämmwerte jeweils gute Werte erreicht werden.Gas mixtures which have the compositions mentioned in claim 2 are used with particular advantage as the disk fillings. In the specified ranges, the mixture composition can be optimally adapted to different sizes and designs of insulating glass units, which, as described, achieves good insulating properties even at low frequencies. All commercially available insulating glass units can therefore be filled with the specified gas mixtures, whereby good values are achieved for the insulation values.

Voraussetzung für die dauerhafte Wirksamkeit der Schallund Wärmedämmung ist die Verwendung geeigneter Dichtmaterialien. Mit Vorteil werden die Scheibenzwischenräume mit Butylkautschuk, Thiokol (eingetragenes Warenzeichen) oder mit Silikonkautschuk abgedichtet. Als Dichtmaterialien kommen aber auch abwechselnd mehrere der genannten Kleber in Frage. Die Verwendung dieser Dicht materialien erweist sich vor allem in der Kombination mit den erfindungsgemäßen Gasfüllungen als günstig. Insbesondere eignet sich Butylkautschuk als elastisches Verbindungsmaterial im Abstandshalter und Silikonkautschuk zum Abdichten gegen die äußere Atmosphäre.The use of suitable sealing materials is a prerequisite for the long-term effectiveness of sound and thermal insulation. The spaces between the panes are advantageously sealed with butyl rubber, thiokol (registered trademark) or with silicone rubber. However, several of the adhesives mentioned also come alternately as sealing materials Question. The use of these sealing materials proves to be particularly advantageous in combination with the gas fillings according to the invention. Butyl rubber is particularly suitable as an elastic connecting material in the spacer and silicone rubber for sealing against the external atmosphere.
