Es ist bereits ein Verfahren zur Herstellung von Verbundsicherheitsglas durch Trockenzusammenfügen in einem Autoklaven bekannt, bei welchem der am Rand durch Klemmen od. dgl. zusammengehaltene Verbund aus mindestens zwei Glasplatten und mindestens einer Zwischenfolie aus thermoplastischem Kunststoff zuerst einem Unterdruck oder Vakuum und danach einem Überdruck bei gleichzeitiger Erwärmung ausgesetzt wird.It is already a process for the production of laminated safety glass by dry joining Known in an autoclave in which the one held together at the edge by clamping or the like Composite of at least two glass plates and at least one intermediate film made of thermoplastic Plastic first a negative pressure or vacuum and then an overpressure at the same time Is exposed to heating.

Dieses Verfahren ist ausgezeichnet, wenn man für die Verbundsicherheitsgläser Glasplatten von üblicher Dicke, d. h. von 2 bis 2,5 mm verwendet. Nimmt man jedoch dünnere Glasplatten, von 1,5 mm oder weniger, so stellt man fest, daß die zwischen den Glasplatten und der dazwischenliegenden thermoplastischen Kunststoffolie eingeschlossene Luft bei der Erwärmungsstufe im Vakuum häufig den Bruch der Glasplatten bewirkt.This process is excellent if one is the usual glass plates for the laminated safety glass Thickness, d. H. from 2 to 2.5 mm used. However, if you use thinner glass plates, of 1.5 mm or less, it is found that the thermoplastic between the glass plates and the intervening Plastic film trapped air during the heating stage in the vacuum often causes the breakage of the glass plates causes.

Es wurde nun gefunden, daß man den Bruch der Glasplatten bei dem vorgenannten Verfahren dadurch verhindern kann, daß man erfindungsgemäß bei Verwendung von dünnen Glasplatten von einer Stärke von etwa 1,5 mm und weniger den Verbund durch die Klemmen zwischen zwei starren Platten, gegebenenfalls unter Zwischenlegen von Folien aus einem EIastomeren, hält. Unter diesen Bedingungen entweicht die Luft wie im Falle normal dicker Glasplatten durch die Ränder des Verbundes, ohne einen Bruch hervorzurufen. It has now been found that the breakage of the glass plates in the aforementioned method thereby can prevent you according to the invention when using thin glass plates of a thickness of about 1.5 mm and less the bond through the clamps between two rigid plates, if necessary with the interposition of foils made of an elastomer. Under these conditions escapes the air through the edges of the composite, as in the case of normal thick glass plates, without causing a break.

Weiterhin wurde gefunden, daß nach diesem Verfahren außerdem der Bruch der in den Verbunden verwendeten dünnen Glasplatten noch weiter vermieden wird, wenn man in weiterer Ausbildung der Erfindung den Verbund der Erhitzung im Autoklaven anfänglich unter atmosphärischem Druck und danach unter Überdruck unterwirft, ohne daß man irgendwann Vakuum in dem Behälter anwendet.Furthermore, it has been found that after this process, the breakage in the compounds used thin glass plates is avoided even further if one is in further training of the Invention of the combination of heating in the autoclave initially under atmospheric pressure and then subjected to positive pressure without ever applying vacuum to the container.

Als Platten verwendet man vorzugsweise Platten von glatter Oberfläche. Polierte Glasplatten von 2 mm oder mehr eignen sich sehr gut, doch kann man auch Metallplatten verwenden. Wenn die Platten nicht vollkommen glatt sind, schiebt man die Folien aus Kautschuk oder anderen Elastomeren ein, die jedoch bei den im Autoklaven angewendeten Temperaturen, d. h. in der Nähe von 140° C noch ausreichend stabil sein müssen.The plates used are preferably plates with a smooth surface. Polished glass plates of 2 mm or more are very suitable, but metal plates can also be used. If the panels aren't perfect are smooth, you push in the rubber or other elastomer sheets, which, however, are the temperatures used in the autoclave, d. H. still sufficiently stable in the vicinity of 140 ° C must be.

Die erfindungsgemäß erhaltenen dünnen Verbundsicherheitsgläser können auch für die Herstellung optischer Gläser verwendet werden.The thin laminated safety glasses obtained according to the invention can also be used for production optical glasses can be used.
