Description

Verfahren zur Herstellung von nichtsplitterbarem Glas Die Erfindung betrifft die Herstellung von nichtsplitterbarem Glas. durch Vereinigung von mehreren Glasplatten. Man hat bereits vorgeschlagen, nichtsplitterbares Glas durch Vereinigung mehrerer Glasplatten und einer Zwischenlage aus :einem Cellulo@seester, insbesondere Acetylcellulose, als Bindemittel herzustellen. Indessen hat sich dieser Kitt aus Acetylcellulose nicht gut bewährt, da geringe Verunreinigungen auf der Oberfläche der Glasplatte die Klebfähigkeit der Acetylcellulose beeinträchtigen. --Gemäß vorliegender Erfindung soll zur Herstellung von nichtsplitterbarem Glas die Zwischenlage eines Celluloseesters beibehalten bleiben, doch soll als eigentlicher Kitt, der sowohl an der Schicht .des Celluloseesters als auch an den Glasplatten fest anhaftet; ein polymerisierter oder teilweise polymerisierter Dialkylester der Itaconsäure verwendet werden.Method of Making Non-Shatterable Glass The invention relates to the production of non-shatterable glass. by uniting several Glass plates. It has already been proposed to use non-shatterable glass by union several glass plates and an intermediate layer made of: a Cellulo @ seester, in particular Acetyl cellulose as a binding agent. In the meantime this putty has run out Acetyl cellulose has not proven its worth as it has little surface contamination the glass plate impair the adhesiveness of the acetyl cellulose. - According to the present Invention is intended for the production of non-splinterable glass, the intermediate layer of a Cellulose ester is retained, but should be used as the actual putty that both firmly adheres to the layer of the cellulose ester as well as to the glass plates; a polymerized or partially polymerized dialkyl esters of itaconic acid are used will.

Man hat bereits versucht, solche polymerisierten Dialkylester der - Itaconsäure herzustellen, aber .die Polymerisation tritt nur sehr langsam ein und ist daher in der Praxis schlecht verwendbar. Es wurde nun gefunden, daß, wenn. man antikatalytische Einflüsse ausschaltet, .die Reaktion in bemerkenswerter Weise beschleunigt werden kann, und zwar dadurch, daß man die Dialkylester .der Itaconsäure auf :etwa z r o° -C erhitzt. Man muß jedoch Vorsorge treffen, daß das Ausgangsmaterial nicht in Berührung mit alkalischen Stoffen, wie gebrann--tem Kalk, oder gewissen organischen Basen, wie Piperidn, kommt, -weil alsdann die Polymerisation stark verzögert wird. Das so gewonnene Produkt ist als Klebemittel für Glas oder anderes undurchsichtiges Material und ganz besonders unter Einschaltung von durchsichtigen und' elastischen Lagen von Celluloseacetat o. dgl. für die Herstellung von nichtsplitterungsfähigem Glas verwendbar.Attempts have already been made to polymerized dialkyl esters of this type - Produce itaconic acid, but the polymerisation occurs very slowly and is therefore difficult to use in practice. It has now been found that if. if anti-catalytic influences are eliminated, the reaction is remarkable can be accelerated by the fact that the dialkyl esters of itaconic acid heated to: about z r o ° -C. However, one must take precautions that the starting material not in contact with alkaline substances such as burnt lime or certain Organic bases, such as piperidene, come because then the polymerization is greatly retarded will. The product obtained in this way is used as an adhesive for glass or other opaque materials Material and especially with the inclusion of transparent and 'elastic' Layers of cellulose acetate or the like for the production of non-splinterable Glass can be used.

Selbstverständlich kann auch das nichtsplitterbare Glas durch Einlagen =von Draht o. dgl. verstärkt werden.Of course, the non-splinterable glass can also be made using inserts = be reinforced by wire or the like.

B eispiel Zwei Glasplatten werden sorgfältig gereinigt und mit etwas verdünnter Säure gewaschen, um das, auf der Oberfiäghe der, Glasplatten befindliche Alkali zu neutralisieren. Die Platten werden ,alsdann mit dem polymerisierten Dialkylester der Itaconsäure von geeigneter Viskosität bestrichen. Dann wird eine Celluloidplatte von der erfordergichen Größe zwischen die Glasplatten gelegt, worauf man die verschiedenen Platten einem Druck unterwirft, bis alle Luftblasen entfernt sind. Die Glasplatte wird alsdann einem Backprozeß, bei einer Temperatur unterworfen, bei welcher die betreffende Celluloseverbindung sich zersetzt. Bei dieser Temperatur bildet der Dalkylester der Itaconsäure einen .guten und nichtsplitterbaren IKi'tt für die Glasplatten. -Example Two glass plates are carefully cleaned and with something Washed with dilute acid to remove the surface on the glass plate Neutralize alkali. The plates are then polymerized with the dialkyl ester the itaconic acid coated of suitable viscosity. Then a celluloid plate of the required size placed between the glass plates, on which the various Pressurize plates until all air bubbles are removed. The glass plate is then subjected to a baking process at a temperature at which the the cellulose compound in question decomposes. At this temperature forms the dalkyl ester of itaconic acid a .good and non-splinterable IKi'tt for the Glass plates. -
