Patentirt im Deutschen Reiche vom g. Mai 1899 ab.Patented in the German Empire by g. May 1899.

Vorliegende Erfindung betrifft die Herstellung eines Klebemittels aus Dextrin, das selbst in kaltem Wasser leicht zur Auflösung gebracht werden kann.The present invention relates to the manufacture of an adhesive from dextrin, which itself can be easily made to dissolve in cold water.

Um aus festem Dextrin in möglichst kurzer Zeit eine concentrirte, stark klebende Lösung zu erhalten, war es bisher nothwendig, das .Dextrin mit kochendem Wasser zu behandeln. Eingehende Versuche haben gezeigt, dafs man die Anwendung von heifsem Wasser zum Auflösen 'des Dextrins entbehren kann, wenn man Dextrin mit wasserlöslichen Kalksalzen versetzt, wodurch dasselbe von kaltem Wasser schnell und in grofser Menge aufgelöst wird. Besonders eignet sich für den vorliegenden Zweck der salpetersaure Kalk.To obtain a concentrated, strongly adhesive solution from solid dextrin in the shortest possible time In order to obtain this, it has hitherto been necessary to treat the dextrin with boiling water. Extensive experiments have shown that hot water can be used for the Dissolving 'the dextrin can do without, if you dextrin with water-soluble calcium salts added, whereby it is quickly and in great quantity dissolved by cold water. Nitric acid lime is particularly suitable for the present purpose.

Eine Mischung vonA mix of

800 g Dextrin und
200 g salpetersaurem Kalk
giebt beim Umrühren mit 1 1 kalten Wassers sofort eine sehr gut klebende Masse.
800 g of dextrin and
200 g of nitric acid lime
When stirred with 1 liter of cold water, it immediately gives a very sticky mass.

Eine solche Mischung von Dextrin mit Kalksalzen hat demgemäfs den Vorzug, dafs deren Auflösung vor Allem weit bequemer und ökonomischer zu bewerkstelligen ist als diejenige des reinen Dextrins. Dadurch, dafs man den Ansatz mit Wasser nicht zu erhitzen braucht, tritt der Geruch des Dextrins viel weniger hervor, " auch zeigt die Lösung eines derartigen Gemisches geringere Gelbfärbung als die des reinen Dextrins. Ein weiterer Vorzug des nach vorliegendem Verfahren erhaltenen Klebemittels ist der, dafs dieses nicht sauer reagirt, wie manche anderen Klebemittel, welche mittelst kalten Wassers zur Auflösung gebracht wurden.Such a mixture of dextrin with calcium salts has accordingly the advantage that the resolution of which is, above all, far more convenient and economical to accomplish than that of pure dextrin. By not heating the approach with water If necessary, the odor of the dextrin is much less noticeable, "the solution also shows one such a mixture has a lower yellow color than that of pure dextrin. Another advantage of the adhesive obtained by the present process is that this is not acidic, like many other adhesives, reacts with cold water for dissolution were brought.

Die leichte Löslichkeit in kaltem Wasser macht ferner das mit Kalksalzen vermischte Dextrin sehr geeignet zur Darstellung von Aquarellfarben.The easy solubility in cold water also makes that mixed with calcium salts Dextrin is very suitable for the representation of watercolors.

Durch Erhöhung des Zusatzes von Kalksalz gelangt man schliefslich zu einer Masse, welche auch in dünnen Schichten nicht austrocknet.By increasing the addition of lime salt one finally arrives at a mass which does not dry out even in thin layers.
