Description

Verfahren zur Herstellung von Verbundglas aus abwechselnden Lagen von Glas und Celluloid Die Herstellung nicht splitternder Glasscheiben durch Zusammenfügen zweier oder mehrerer solcher milt je einer Zwischeniage einer durchsichtigen Folie, wie Cellluloid oder ähnlichen Materialien; isst bekannt.Process for the production of laminated glass from alternating layers of glass and celluloid The production of non-splintering glass panes by joining two or more such panes each with an intermediate layer of a transparent film such as celluloid or similar materials; eats known.

Die. Herstellung solcher Verbundgläser geschieht in der Regel auf die Weise, da.ß ein Celluloüdblatt innerhalb eines Lösungsmittels (Alkohol, Aceton, Amylacetat, Fuselöl mit oder ohne Beimischungen, wie. Wasser, Kampfer, ätherische öle) zwischen die Glasplatten gelegt wird, worauf das ganze Paket herausgenommen und gepre ßt, -allenfalls auch erwärmt wird. Zur Erhöhung der Haftfestigkeüt des Celluloids am. den Glasplatten, wenden diese vorerst mit ,einer Gelatineschicht überzogen; dem Lösungsmittel können gewisse Mengen Wasser, Eisessig a..dgl. noch. beigemengt werden.The. Production of such laminated glasses usually happens on the way that a cellulose leaf can be placed in a solvent (alcohol, acetone, Amyl acetate, fusel oil with or without additives, such as. Water, camphor, essential oils) is placed between the glass plates, whereupon the whole package is removed and pressed, if necessary also heated. To increase the adhesive strength of the Celluloids on the glass plates, turn them with a gelatin layer for the time being overdrawn; The solvent can add certain amounts of water, glacial acetic acid a..dgl. still. be added.

Diese Verfahren haben den Nachteil, daß das Cellutloidbl.attgrößere Flüss igkeitsmengenaufinin=t, ,als für den Zweck ,der Vereinigung mit den Glasplatten notwendig ist, weil. die Lösungsmilttel sehr rasch in das CeKuleid Die nachteiligen Foilgen dieser Tatsache rcnachen sich dann in einer eirhöhter1 Schrumpfung des Celluloids bemerkbar, wenn es inn Laufe der Zeit das Lösungsmittel vertiert. Überdies erfordert schon die Entfernung des überschüssigen Lösungsmittels bei ,der Herste-lnung gewisse Vorsichttsmaß,-regeln, @endl`ich. aber tritt dadurch eine weitgehende Zersetzung des Ce#,lllu@loids eine, welche sich in Kris;tal!fausscheidungen;, Trübungen usw. bemerkbar macht.These methods have the disadvantage that the cellutloid leaf is larger Liquid quantity onin = t, as for the purpose of union with the glass plates is necessary because. the solvent very quickly in the CeKuleid The disadvantageous Follow-up to this fact then results in an increased shrinkage of the celluloid noticeable when it turns the solvent over in the course of time. Moreover, requires the removal of the excess solvent already contributes to the production process Cautionary measure, rules, @ finite. but this results in a far-reaching decomposition des Ce #, lllu @ loids, which are in crystalline precipitations, opacities, etc. makes noticeable.

Man, hat deshalb bereits. versucht; das Lösungsmittel .durch Beimengungen so abzustimmen, @daß die Quellungsgeschwindi'gkeit vermindert wird, und benutzt hierzu schwerfiücht%ge Lösungsmittel, wie Fuselöl, in welchem Kampfer und ätherische Öle- gelöst. sind, die erst durch spätere Wärmebehandlung wirksam gemacht werden.One has, therefore, already. tries; the solvent. through admixtures to be adjusted so that the swelling speed is reduced and used in addition, poorly volatile solvents, such as fusel oil, in which camphor and essential oils Oil-dissolved. which are only made effective through subsequent heat treatment.

Die Erfindung besiteht nun darin, das Eindringen größerer Flüssigkeitsmengen in das Celluldiidblatt dadurch zu verhindern, daß auf die Oberflächen. der CelluiloidplatGe vor der Behandlung mit dem Lösungsmittel ein fettiger oder wachsartiger Stoff aufgetragen wird. Es bleibt dann der Kern des Cegluloids wäh: rend der Herstellung des Verbundglases völlig unverändert, und nur an den Oberflächen findet eine Erweichung in dem Maße statt, daß die Verkliebung gesichert erscheint. Nach dem Auftragen des Schutzstoffes bleibt die Cel@luloidplatte zweckmäßig längere Zeit (z. B. 12 bis 24 Stunden) sich. selbst überlassen,.The invention now consists in the penetration of larger amounts of liquid in the Celluldiidblatt thereby to prevent that on the surfaces. the CelluiloidplatGe a greasy or waxy substance applied before the treatment with the solvent will. The core of the cegluloid then remains during the manufacture of the laminated glass completely unchanged, and only the surfaces soften to the same extent instead of the fact that the love seems certain. After applying the protective material The Cel @ luloid plate expediently remains in place for a longer period of time (e.g. 12 to 24 hours). left to yourself.

Als solche Stoffe ,eignen sich besonders die Ester des Glycerins mit den niederen Fettsäuren (sei :es im reinen Zustand oder als un,-gereiinigte Geimische), wie sie bei der Acylierung erhalten werden, ferner de Ester höherer Fettsäuren mit niederen; Alkaholern, endlich .auch höhere Alkohole für sich aliek.The esters of glycerine are particularly suitable as such substances the lower fatty acids (be it in the pure state or as uncleaned mixtures), as they do in acylation are obtained, furthermore the esters of higher Fatty acids with lower ones; Alcoholic people, finally, also higher alcohols for themselves aliek.

Zum Augenschutz oder für Signalzwecke kann es wünschenswert oder erforderlich sein, auch: farbige oder abgetönte Verbmdglä ser nach: -dem Verfahren herzustellen. Zu dien sein Zwecke werden vorher in b&;annter Weise gefärbte oder gemusterte Gelluloidplattem oder auch: farbige oder gemusterte Glasplatten benutzt.It may be desirable or necessary for eye protection or signaling purposes also: colored or tinted composite glasses according to: -the process. To serve its purposes they are previously dyed or patterned in a b &; annter manner Gelluloid plates or also: colored or patterned glass plates are used.
