KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Verfahren zur Herstellung eines Produktes, welches als Ersatz für Nitrocelluloseverbindungen, wie Zelluloid u. dgl., verwendet werden kann. Die Masse weist große Härte und Festigkeit auf und bewahrt die Eigenschaften fortdauernd.The invention relates to a method for producing a product, which as a replacement for nitrocellulose compounds such as celluloid and the like. the The mass has great hardness and strength and maintains the properties permanently.
Das Verfahren besteht darin, daß der Acetyl-The procedure consists in that the acetyl
cellulose ein Körper zugesetzt wird, welcher jede Neigung zur Zersetzung aufhält und dadurch eine Verschlechterung verhütet. Der so hergestellte Stoff ist hart und fest und behält seine charakteristischen Eigenschaften auch beim Lagern sowie bei jeder Behandlungsweise. cellulose a body is added, which stops any tendency to decompose and thereby prevents deterioration. The fabric produced in this way is hard and strong and holds its characteristic properties also during storage as well as with any kind of treatment.
Man hat bereits früher vorgeschlagen, gewisse Acetylcellulosemischungen als Ersatzmittel für Celluloid ο. dgl. zu verwenden. Indessen ergaben sich bei den Versuchen, Acetylcellulosemischungen für derartige Zwecke zu benutzen, viele Schwierigkeiten. Die vorgeschlagenen Ersatzmittel wiesen Mängel auf, besonders in Härte und Festigkeit, und zeigten in vielen Fällen Brüchigkeit, welche von Zersetzung herrührte.It has previously been suggested that certain acetyl cellulose mixtures be used as substitutes for celluloid ο. Like. To use. In the meantime, the tests showed acetyl cellulose mixtures to use it for such purposes poses many difficulties. The proposed substitutes showed deficiencies, especially in hardness and strength, and in many cases showed brittleness resulting from decomposition originated.
Es hat sich nun gezeigt, und darin besteht die Erfindung, daß man durch Zusatz von Harnstoff zu einer Acetylcellulosemischung oder -lösung Stoffe erhalten kann, welche ihre Härte und Festigkeit unbegrenzt lange Zeit bewahren und keinerlei Brüchigkeit aufweisen.It has now been shown, and that is the invention, that by adding Urea to an acetylcellulose mixture or solution can contain substances which Preserve hardness and strength indefinitely and show no brittleness.

Die Menge des zugesetzten Harnstoffes beträgt ι bis 2 Teile auf 100 Teile Acetylcellulose in der verwendeten Acetylcellulosemischung oder -lösung. Indessen können diese Mengenverhältnisse bis zu einem gewissen Grade modifiziert werden; es hängt dies von der Art der Acetylcellulose ab.The amount of urea added is ι to 2 parts per 100 parts of acetyl cellulose in the acetyl cellulose mixture or solution used. However, these proportions be modified to some extent; it depends on the nature of this Acetyl cellulose.
Ein beispielsweise aus Acetylcellulose, Triphenylphosphat und Harnstoff hergestelltes Produkt ist nicht entflammbar, transparent und besitzt einen hohen Grad von Härte und Festigkeit, welche infolge der Gegenwart von Harnstoff dauernd erhalten bleibt.One made, for example, from acetyl cellulose, triphenyl phosphate and urea Product is non-flammable, transparent and has a high degree of hardness and Strength which is permanently retained due to the presence of urea.
Das nach der Erfindung hergestellte Produkt kann vorzugsweise zur Herstellung von festen Überzügen benutzt werden, obgleich es auch vorteilhaft für andere Zwecke verwendbar ist.The product produced according to the invention can preferably be used for the production of solid coatings can be used, although it can also be used advantageously for other purposes is.
