Description
Verfahren zur Herstellung von splittersicherem Verbundglas Zusatz zum Patent 731932 Gegenstand des Hauptpatentes 73I g32 ist die Herstellung von splittersicherem Verbundglas, wobei als Zwischenschicht Acetale aus verseiften Mischpolymerisaten aus Vinylestern mit Maleinsäure, Maleinsäureanhydrid oder Maleinsäureestern verwendet werden.Process for the production of shatterproof laminated glass Addition to patent 731932 The subject of the main patent 73I g32 is the production of shatterproof laminated glass, whereby acetals from saponified copolymers of vinyl esters with maleic acid, maleic anhydride or maleic acid esters are used as the intermediate layer.
Es wurde nun gefunden, daß nicht nur die Acetale derartiger verseifter Mischpolymerisate als Zwischenschicht zur Herstellung von Sicherheitsglas geeignet sind, sondern ganz allgemein -Acetale solcher Polymerisate, die außer Hydroxylgruppen noch eine gewisse Anzahl von Carboxylgruppen im Molekül enthalten. DieAcetale derartiger Polymerisate sind beispielsweise bereits in der Patentschrift 592 233 beschrieben. Beispiele z. Zwischen zwei Glasscheiben mit planparallelen Flächen wird eine Folie von o,6 mm Stärke gebracht, die hergestellt wurde aus dem Isobutyraldehydacetal des Verseifungsproiuktes eines Mischpolymerisates aus 12 Gevichtsteilen Vinylacetat und 2 Gewichtsteilen Acrylsäuremethylester, dem noch 2o 1/o eines Weichmachers zugesetzt werden. Durch langsam steigenden Druck «-erden die beiden Glasscheiben in an sich bekannter Weise bei etwa gö°- aufeinandergepreßt, wobei zu beachten ist, daß keine Luftblase eingefangen wird.It has now been found that not only the acetals of such saponified copolymers are suitable as an intermediate layer for the production of safety glass, but also quite generally acetals of such polymers which, in addition to hydroxyl groups, also contain a certain number of carboxyl groups in the molecule. The acetals of such polymers are already described in patent specification 592 233, for example. Examples e.g. Between two panes of glass with plane-parallel surfaces, a film of 0.6 mm thickness, which was made from the isobutyraldehyde acetal of the saponification product of a copolymer of 12 parts by weight of vinyl acetate and 2 parts by weight of methyl acrylate, to which 2o 1 / o of a plasticizer is added. The two panes of glass are pressed onto one another in a manner known per se by slowly increasing pressure -earths at about gö °, whereby it must be ensured that no air bubble is captured.
Man erhält ein Sicherheitsglas, das sowohl die Eigenschaft hat, durch Schlag nur schwer zu zerbrechen als auch bei schließlich eintretendem Bruch Bruchstücke zu geben, die infolge der sehr elastischen und feste Haftung veranlassenden Zwischenschicht im Zusammenhang untereinander bleiben. Und zwar ist diese Bruchsicherheit in einem Temperaturintervall von .-1- 5o bis - gö'-' praktisch unverändert.A safety glass is obtained that has both the property through Impact is difficult to break as well as broken fragments eventually occurring to give the intermediate layer that causes the very elastic and firm adhesion stay in context with each other. And that is this break resistance in one Temperature range from.-1- 5o to -gö'- 'practically unchanged.
2. Verwendet man statt des obengenannten Acetals ein solches des Isohexylaldehyds mit dem verseiften Mischpolymerisat von 8 Gewichtsteilen Vinv lacetat und z Gewichtsteil Crotonsäureäthylester, so erhält man ei» Verbundglas mit ähnlich guten Eigenschaften.2. If an acetal of isohexylaldehyde is used instead of the above-mentioned acetal with the saponified copolymer of 8 parts by weight of Vinv lacetat and z part by weight Ethyl crotonate, then laminated glass with similarly good properties is obtained.
Man kann die Belegung der Scheiben uatürlich auch so vornehmen, daß man Lösungen der Polymeren auf die Scheiben aufträgt, das Lösungsmittel abdunsten läßt und dann die blasenfreie Verklebung vornimmt.You can of course make the assignment of the panes so that solutions of the polymers are applied to the panes and the solvent is evaporated off leaves and then makes the bubble-free bonding.
