Description
Es wurde gefunden, daß der Polyvinylalkohol oder seine noch in Wasser löslichen oder quellbaren Derivate sich infolge ihrer hohen Elastizität in ausgezeichneter Weise zur Herstellung von Verbundglas eignen.It has been found that the polyvinyl alcohol or its are still soluble in water or swellable derivatives are excellent due to their high elasticity suitable for the production of laminated glass.
In Betracht kommt der Polyvinylalkohol in seinen verschiedenen durch Viskositätsmessung bestimmbaren Modifikationen, und zwar hiervon besonders die hochviskosen und damit elastischen Modifikationen.Various types of polyvinyl alcohol can be considered by measuring the viscosity determinable modifications, especially the highly viscous and thus elastic modifications.
Wasserlösliche oder in Wasser quellbare Derivate, die für die Herstellung von Verbundglas Verwendung finden können, können beispielsweise erhalten werden durch teilweise Verseifung von Polyvinylester^ durch teilweise Veresterung von Polyvinylalkohole^ durch Einwirkung von Aldehyden auf Polyvinylalkohole, durch Verseifung des Halogens in Polyvinylhalogenfettsäureestern oder durch Einwirkung von Äthylenoxyd auf Polyvinylalkohole. Water-soluble or water-swellable derivatives used in the manufacture of laminated glass Can be used, for example, can be obtained by partially saponifying polyvinyl ester ^ by partially Esterification of polyvinyl alcohols ^ by the action of aldehydes on polyvinyl alcohols, by saponification of the halogen in polyvinyl halide fatty acid esters or by the action of ethylene oxide on polyvinyl alcohols.
Die Verwendung des Polyvinylalkohols und der wasserlöslichen Polyvinylverbindungen zur Herstellung von Verbundglas erfolgt in der Weise, daß man aus ihnen Filme von gewünschter Dicke herstellt, z. B. durch Lösen in Wasser und Auftrocknenlassen auf einer ebenen, glatten Fläche, und die entstandenen Filme dann mit Hilfe zweier verklebender Schichten, beispielsweise aus Gelatine oder aus einer Lösung von Polyvinylverbindungen (in organischen Lösungsmitteln), zum Verbinden der Glasscheiben benutzt. Die auf diese Weise hergestellten Verbundglasscheiben zeichnen sich durch große Splittersicherheit und Lichtdurchlässigkeit aus, sie sind den mit Cellulosederivaten hergestellten Sicherheitsgläsern überlegen. Man hat bereits vorgeschlagen, Polyvinylalkohol zum Kleben zu verwenden, auch sind als Zwischenschichten für Verbundgläser bereits Polyvinyl- und Polyacrylester verwendet worden. Vor den so hergestellten Verbundgläsern bilden die Polyvinylalkohol als Zwischenschicht enthaltenden Gläser den Vorteil einer erhöhten Schlagfestigkeit. The use of polyvinyl alcohol and water-soluble polyvinyl compounds for the production of laminated glass is carried out in such a way that films of the desired type are made from them Thickness manufactures, e.g. B. by dissolving in water and letting it dry on a flat, smooth surface, and the resulting Then films with the help of two adhesive layers, for example made of gelatin or from a solution of polyvinyl compounds (in organic solvents), for joining the glass panes used. The laminated glass panes produced in this way are characterized by their high level of protection against splintering and light transmission, they are the safety glasses made with cellulose derivatives think. It has already been proposed to use polyvinyl alcohol for gluing, also as intermediate layers Polyvinyl and polyacrylic esters have already been used for laminated glasses. Before the so Laminated glasses produced form those containing polyvinyl alcohol as an intermediate layer Glasses have the advantage of increased impact resistance.
Auf zwei Glasplatten von 3 mm Dicke wird eine io°/„ige Lösung eines hochviskosen Polyvinylalkohols in Wasser ausgegossen. Bei langsamem Verdunsten des Wassers hinterbleibt ein klar durchsichtiger, blasenfreier Film, der fest auf der Glasplatte haftet. Nach völligem Trocknen werden die Scheiben mit den Filmseiten aufeinandergelegt und bei i2o° mit 5 Atmosphären Druck aufeinander-' gepreßt. Die Glasscheiben werden durch den außerordentlich zähen Film fest zusammengehalten. An 10% solution of a highly viscous one is placed on two glass plates 3 mm thick Polyvinyl alcohol poured into water. Remains when the water evaporates slowly a clear, bubble-free film that adheres firmly to the glass plate. To The panes are placed on top of each other with the sides of the film and are completely dry i2o ° pressed together with 5 atmospheres pressure. The panes of glass are through the extraordinarily tough film held together tightly.
