  Verfahren zur Herstellung formbarer elastischer Leimmasse. 



   Die Herstellung hochelastischer Gebrauchsgegenstände aus Leim an Stelle von Gummifabrikaten bereitet hinsichtlich der Formgebung grössere Schwierigkeiten, wenn Glyzerin und Chromate nicht zur Verfügung stehen. Es hat sich nun gezeigt, dass auch unter Verwendung von wassergelösten Glyzerin-Ersatzmitteln (Chloride der zweiwertigen Metalle, Zucker, Melasse) eine gute Formbarkeit der Masse erzielt wird, wenn zu der wässerigen Lösung von Leim und Chloriden usw. mit oder ohne Beimengung von Mineralstoffen ausser Aldehyden oder Aldehyde abgebenden organischen Substanzen Alkalihydroxyde oder-Karbonate zugesetzt werden. 



   Beispiel : Eine Lösung, bestehend aus 100 Teilen Leim, 5 Teilen Pottasche, 40 Teilen Wasser wird mit   50   Teilen Schwerspat, 40 Teilen Chlorzink, 10 Teilen Acetaldehydammoniak oder Hexamethylentetramin innig verrührt, in entsprechende Formen (z. B. 
 EMI1.1 
 
Die Wirksamkeit des Alkalizusatzes beruht auf der Möglichkeit, die wässerige Leim-   lösung ganz unverhältnismässig   konzentrierter anzusetzen als ohne diesen Zusatz. Die hohe Konzentration der Leimlösung ist aber unerlässlich, damit die das Endprodukt bildende plastische Masse tatsächlich die von Fabrikaten aus Gummiersatzmassen geforderte Festigkeit und Formbeständigkeit besitzt.

   Die beim Zusatz von Clorzink, Chlormagnesium oder dgl. eintretende Fällung hindert die beschriebene Arbeitsweise keineswegs, weil diese Reaktion in der sehr stark kolloidalen Lösung derart   verzögert   wird, dass sie praktisch auf den Verlauf des Arbeitsganges keinen Finfluss auszuüben vermag. Aus dem gleichen Grunde wirkt ein Zusatz von Zucker ähnlich wie solcher von Chlorzink.

  Process for the production of malleable elastic glue.



   The production of highly elastic commodities from glue instead of rubber products presents greater difficulties in terms of shaping if glycerine and chromates are not available. It has now been shown that even with the use of water-based glycerine substitutes (chlorides of divalent metals, sugar, molasses), a good malleability of the mass is achieved if the aqueous solution of glue and chlorides etc. with or without the addition of minerals in addition to aldehydes or organic substances releasing aldehydes, alkali metal hydroxides or carbonates are added.



   Example: A solution consisting of 100 parts of glue, 5 parts of potash, 40 parts of water is thoroughly mixed with 50 parts of heavy spar, 40 parts of zinc chloride, 10 parts of acetaldehyde ammonia or hexamethylene tetramine, in appropriate forms (e.g.
 EMI1.1
 
The effectiveness of the alkali addition is based on the possibility of preparing the aqueous glue solution in a disproportionately more concentrated manner than without this addition. However, the high concentration of the glue solution is essential so that the plastic compound forming the end product actually has the strength and dimensional stability required by products made from rubber substitutes.

   The precipitation occurring with the addition of chlorzinc, chloromagnesium or the like. In no way prevents the described procedure, because this reaction is delayed in the very strong colloidal solution so that it is practically unable to exert any influence on the course of the operation. For the same reason, adding sugar has a similar effect to adding zinc chloride.
