Description

Sicherheitsglas Die bekannten sogenannten splitterfesten Mehrfachglasscheiben -für Automobile und sonstige Fahrzeuge bestehen in der Hauptsache aus zwei möglichst planen Glasscheiben, die mit einer Celluloidzwischenlage verbunden sind. Die Verwendung des Celluloids hierfür bietet ziemlich große Schwierigkeiten, da sich infolge der chemischen Zusammensetzung die Zwischenlage leicht verfärbt, wodurch die Gesamtglasscheibe nicht mehr die ursprüngliche Durchsichtigkeit besitzt.Safety glass The well-known so-called shatterproof multiple glass panes -for automobiles and other vehicles consist mainly of two if possible flat panes of glass bonded with a celluloid layer. The usage of the celluloid for this offers rather great difficulties, since as a result of the chemical composition the intermediate layer slightly discolored, causing the overall glass pane no longer has the original transparency.

Die vorliegende Erfindung bezieht sich nun darauf, daß an Stelle von Celluloid ein Film aus Kondensationsprodukten von mehrwertigen Alkoholen und mehrbasischen Säuren, z. B. aus Phthalsäureanhydrid und Glycerin, hergestellt wird, der im warmen Zustand zwischen beide Platten eingebracht und verpreßt wird.The present invention now relates to that in lieu of Celluloid is a film made from condensation products of polyhydric alcohols and polybasic alcohols Acids, e.g. B. from phthalic anhydride and glycerol, which is produced in the warm State is introduced between the two plates and pressed.

Die bekannte Durchsichtigkeit dieses Kondensationsproduktes, seine vorzügliche Oberflächenbindefähigkeit und chemische Indifferenz gegenüber Witterungseinflüssen machen es für den angestrebten Zweck im besonderen Maße geeignet.The well-known transparency of this condensation product, his excellent surface binding properties and chemical indifference to weather influences make it particularly suitable for the intended purpose.

Die Verwendung von Kondensationsprodukten anderer Art, z. B. von Harnstoffkondensationsprodukten als Zwischenschicht, ist bereits vorgeschlagen worden, ohne daß dabei Gläser erhalten wurden, die in jeder Hinsicht den gestellten Anforderungen entsprechen. Die notwendige Haftfähigkeit und die Unempfindlichkeit gegen die Einflüsse der Witterung und des Sonnenlichtes konnten auf diesem Wege nicht erhalten werden. Erst die Verwendung der aus Glycerin und Phthalsäureanhydrid erhaltenen Kondensationsprodukte ermöglicht die Herstellung vollkommener Sicherheitsgläser. Statt dieses Kondensationsproduktes können auch solche benutzt werden, bei denen ein Teil des Glycerins durch- andere mehrwertige Alkohole, ,z. B. Glykol, oder bei denen ein Teil der Phthalsäure durch andere organische Säuren, wie Bernsteinsäure, in üblicher Weise ersetzt ist, oder denen auf bekannte Weise Weichmachungsmittel zugesetzt sind.The use of other types of condensation products, e.g. B. of urea condensation products as an intermediate layer, has already been proposed without glasses being obtained that meet the requirements in every respect. The necessary Adhesiveness and insensitivity to the effects of weather and the Sunlight could not be preserved in this way. First the use the condensation products obtained from glycerol and phthalic anhydride the production of perfect safety glasses. Instead of this condensation product It is also possible to use those in which part of the glycerine is carried by others polyhydric alcohols, e.g. B. glycol, or where part of the phthalic acid by other organic acids, such as succinic acid, is replaced in the usual way, or to which plasticizers are added in a known manner.
