Dekoratives VerbundglasDecorative laminated glass
BeschreibungDescription
Die Neuerung betrifft ein dekoratives Verbundglas aus wenigstens zwei Glasscheiben und einer ein farbiges Bild oder ein farbiges Dekor aus organischen Farbstoffen enthaltenden Zwischenschicht, die ihrerseits aus zwei miteinander verbundenen Polyvinylbutyralfolien besteht, von denen die eine PVB-Folie auf der mit der anderen PVB-Folie verbundenen Seite mit dem Bild oder dem Dekor versehen ist.The innovation relates to a decorative laminated glass made of at least two glass panes and an intermediate layer containing a coloured image or a coloured decoration made of organic dyes, which in turn consists of two polyvinyl butyral films bonded together, of which one PVB film is provided with the image or decoration on the side bonded to the other PVB film.
Eine dekorative Verbundglasscheibe dieser Art ist aus der DE 2837768 Al bekannt, wobei bei dieser bekannten Verbundglasscheibe das Dekor aus organischen oder aus anorganischen Farbstoffen bestehen kann. Die üblichen Polyvinylbutyralfolien weisen eine Dicke von weniger als 0,4 mm auf. Wenn das farbige Bild oder Dekor unter diesen Bedingungen aus organischen Farben besteht, bleichen die Farben unter der Einwirkung der UV-Strahlen im Laufe der Zeit aus. Dekorative Verbundglasscheiben dieser Art sind also nicht lichtbeständig.A decorative laminated glass pane of this type is known from DE 2837768 Al, whereby the decoration in this known laminated glass pane can consist of organic or inorganic dyes. The usual polyvinyl butyral films have a thickness of less than 0.4 mm. If the colored image or decoration consists of organic colors under these conditions, the colors will fade over time under the influence of UV rays. Decorative laminated glass panes of this type are therefore not lightfast.
Der Neuerung liegt die Aufgabe zugrunde, ein dekoratives Verbundglas des eingangs genannten Aufbaus bereitzustellen, das auch bei Verwendung von organischen Farbstoffen eine hohe Lichtbeständigkeit aufweist.The innovation is based on the task of providing a decorative laminated glass of the structure mentioned above, which has a high light resistance even when organic dyes are used.
Das Verbundglas gemäß der Neuerung zeichnet sich dadurch aus, daß die das Bild oder Dekor aus organischen Farben zwischen sich schließenden Polyvinylbutyralfolien eine erhöhte UV-Absorption aufweisen.The laminated glass according to the innovation is characterized by the fact that the image or decoration made of organic colors between the polyvinyl butyral films have an increased UV absorption.
Da auch die üblichen Polyvinylbutyralfolien eine gewisse UV-Absorption zeigen, kann der gewünschte Zweck dadurchSince the usual polyvinyl butyral films also show a certain UV absorption, the desired purpose can be achieved
erreicht werden, daß PVB-Folien üblicher Zusammensetzung, jedoch mit einer größeren Dicke verwendet werden, so daß hierdurch ein ausreichender Lichtschutz der organischen Farben gewährleistet ist. Es hat sich gezeigt, daß diese Bedingung erfüllt ist, wenn PVB-Folien üblicher Zusammensetzung, jedoch mit einer Dicke von wenigstens 0,76 mm, verwendet werden. Selbstverständlich können auch dünnere Folien aus PVB oder aus anderen thermoplastischen Materialien verwendet werden, wenn die UV-Absorption dieser Materialien, gegebenenfalls aufgrund geeigneter Zusätze, entsprechend erhöht ist.This can be achieved by using PVB films of the usual composition, but with a greater thickness, so that sufficient light protection of the organic colors is guaranteed. It has been shown that this condition is met when PVB films of the usual composition, but with a thickness of at least 0.76 mm, are used. Of course, thinner films made of PVB or other thermoplastic materials can also be used if the UV absorption of these materials is increased accordingly, if necessary due to suitable additives.
Die farbigen Bilder oder Dekore können grundsätzlich nach allen bekannten Auftragsverfahren unmittelbar auf eine der beiden PVB-Folien aufgebracht werden, beispielsweise von Hand, nach dem Airbrush-Verfahren oder nach einem Druckverfahren, beispielsweise dem Siebdruckverfahren.The colored images or decorations can basically be applied directly to one of the two PVB films using all known application methods, for example by hand, using the airbrush method or using a printing method, such as screen printing.
Eine neuerungsgemäß ausgebildete Verbundglasscheibe kann auch mit einer oder mehreren weiteren Schichten kombiniert werden, zum Beispiel mit einer oder mehreren farbigen Folien, wodurch die dekorativen und gestalterischen Möglichkeiten erweitert werden.A laminated glass pane designed in accordance with the innovation can also be combined with one or more additional layers, for example with one or more colored films, thereby expanding the decorative and design options.
Anhand der Zeichnung, die einen Schnitt durch eine bevorzugte Ausführungsform der Erfindung darstellt, wird der Gegenstand der Neuerung näher erläutert.The subject matter of the innovation is explained in more detail with reference to the drawing, which shows a section through a preferred embodiment of the invention.
Die Verbundglasscheibe umfaßt zwei Glasscheiben 1, 2 aus farblosem Floatglas von jeweils 4 mm Dicke. Die beiden Floatglasscheiben 1, 2 sind über die thermoplastische Zwischenschicht 3 miteinander verbunden, wobei die Verbindung nach einem der bekannten Verbindeverfahren unter Anwendung von Wärme und Druck erfolgt. Die Zwischenschicht 3 setzt sich zusammen aus zwei Folien 4, 5 aus Polyvinylbutyral. Jede der beiden Folien 4 und 5 hat eine Dicke von 0,76 mm. Vor dem Verbindeprozeß werden die beidenThe laminated glass pane comprises two glass panes 1, 2 made of colorless float glass, each 4 mm thick. The two float glass panes 1, 2 are connected to one another via the thermoplastic intermediate layer 3, whereby the connection is made using one of the known bonding processes using heat and pressure. The intermediate layer 3 is made up of two films 4, 5 made of polyvinyl butyral. Each of the two films 4 and 5 has a thickness of 0.76 mm. Before the bonding process, the two
Folien 4 und 5 aufeinandergelegt. Sie verschmelzen bei dem Verbindeprozeß zu einer zusammenhängenden Schicht.Films 4 and 5 are placed on top of each other. During the bonding process they fuse together to form a continuous layer.
Bevor die beiden Folien 4 und 5 zusammengelegt werden, wird auf diejenige Oberfläche der Folie 5, die mit der Folie 4 in Kontakt kommt, ein einfarbiges oder mehrfarbiges Dekor aus einer organischen Acrylfarbe 6 nach einem beliebigen bekannten Verfahren aufgebracht. Dabei wird die Farbe 6 in einer solchen Konzentration aufgebracht, daß die Transparenz durch die Farbschicht hindurch erhalten bleibt. Beim späteren Verbindeprozeß unter Anwendung von Wärme und Druck dringt die Farbe 6 oberflächlich in die PVB-Folien 4 und 5 ein. Trotz der vorhandenen Farbschicht verschmelzen die beiden PVB-Folien 4 und 5 beim Verbindeprozeß vollständig miteinander. Die fertige Verbundglasscheibe weist auch mit der in ihr enthaltenen farbigen Abbildung 6 die für Verbundglas bekannten Sicherheitsglaseigenschaften auf. Die hierfür üblichen Tests wurden an Musterscheiben mit positivem Ergebnis bestanden. Auch bei längerer intensiver UV-Bestrahlung zeigen die Farben keine Vergilbungserscheinungen.Before the two films 4 and 5 are put together, a single-colour or multi-coloured decoration made of an organic acrylic paint 6 is applied to the surface of the film 5 that comes into contact with the film 4 using any known method. The paint 6 is applied in such a concentration that the transparency is maintained through the colour layer. During the subsequent bonding process using heat and pressure, the paint 6 penetrates the surface of the PVB films 4 and 5. Despite the existing colour layer, the two PVB films 4 and 5 fuse together completely during the bonding process. The finished laminated glass pane, with the coloured image 6 contained in it, also has the safety glass properties known for laminated glass. The usual tests for this were passed on sample panes with positive results. Even with prolonged, intensive UV radiation, the colours show no signs of yellowing.
