  Verfahren zur Herstellung eines unbrennbaren Zelluloidersatzes, insbesondere   für Films,  
Präge-und Druckformen u. dgl. 



   Es ist mehrfach vorgeschlagen worden, in der Fabrikation des Zelluloids die Nitro-   zellulosen   durch die   längst   bekannten Azetylzellulosen zu ersetzen, um die Feuergefährlichkeit herabzusetzen. Andererseits werden zum selben Zwecke als Ersatz für Kampfer bei der Herstellung von zelluloidähnlichen Produkten aus Azetylzellulosen one Reihe von Körpern vorgeschlagen, wie :   Tolnolsulfamid,   Naphtalin, Oxalsäuremethylester, Phtalsäuremethylester, Trichlorbenzol, ferner die Phenole,   Chloralhydrat   und   Chioralalkoholate.   



   Durch alle diese Kombinationen werden nun zwar   zelluloid hnliche   Substanzen erhalten, bei denen eine geringere   Feuergefährlichlieit   als beim   Zelluloid vorhanden   ist. Alle durch diese Kombination erhaltenen Körper nehmen aber die Flamme an und brennen in sich weiter, ohne dass die Flamme von aussen genährt wird. 



   Gegenstand vorliegender Erfindung bildet nun die Herstellung eines Produktes, das in bezug auf Durchsichtigkeit, Elastizität, Bildsamkeit in der Wärme usw. dem   gewöhnlichen   Zelluloid gleichwertig ist, diesem gegenüber jedoch den grossen Vorzug hat, absolut nicht zu brennen und vollständig geruchlos zu sein. 



   Das Produkt wird hergestellt nach den gewöhnlichen Zelluloidfabrikationsmethoden, jedoch unter Verwendung von einerseits Azetylzellulosen und andererseits den Phenol-,   Kresol- oder Naphtolestern   oder deren Derivaten und eventuell unter Zuhilfenahme von geeigneten Füllmaterialien. Allerdings sind solche Ester zur Zelluloidfabrikation mit Nitrozellulose bereits vorgeschlagen, jedoch wird der Zweck vorliegender Erfindung, ein unbrennbares Produkt zu erhalten, mit Nitrozellulosen nicht erreicht. 



   Das neue Produkt ist selbst in dünnster Plattform nicht brennbar. In der   gewöhu-   lichen Dicke eines Films einer Flammo ausgesetzt, schmilzt an der überhitzten Stelle, aber auch nur dort, das Produkt in sich   zusammen,   ohne auch nur die Spur einer Flammenerscheinung zu zeigen. 



   Es ist also ein Material geschaffen, das in jeder Beziehung, wie z. B. Durchsichtigkeit,
Elastizität und Zugkraft, Bildsamkeit in der Wärme, Anfärbungsvermögen, Ausblasfähigkeit   erc.,   dem gewöhnlichen Zelluloid gleichwertig ist, dabei aber weder brennbar noch explosiv ist. Das neue Produkt ist ein absolut harmloser Körper, der weder in seiner Fabrikation noch in seiner Verarbeitung, wie z. B. zu Film, Druckstöcken, Gebrauchs- gegenständen etc., Personen-oder Materialschaden verursachen kann.

  Process for the production of an incombustible celluloid substitute, in particular for film,
Embossing and printing forms, etc. like



   It has been proposed several times to replace the nitrocelluloses in the manufacture of celluloids with the long-known acetylcelluloses in order to reduce the risk of fire. On the other hand, as a substitute for camphor in the manufacture of celluloid-like products from acetylcelluloses, a number of substances are proposed for the same purpose, such as: tolnolsulfamide, naphthalene, methyl oxalate, methyl phthalate, trichlorobenzene, and also the phenols, chloral hydrate and chioral alcoholates.



   All of these combinations result in celluloid-like substances which are less flammable than celluloid. However, all bodies obtained through this combination accept the flame and continue to burn within themselves without the flame being nourished from outside.



   The subject of the present invention is the manufacture of a product which is equivalent to ordinary celluloid in terms of transparency, elasticity, malleability, etc., but which has the great advantage over it of absolutely not burning and being completely odorless.



   The product is manufactured according to the usual celluloid manufacturing methods, but using acetyl celluloses on the one hand and phenol, cresol or naphthol esters or their derivatives on the other, and possibly with the aid of suitable filling materials. However, such esters have already been proposed for celluloid production with nitrocellulose, but the purpose of the present invention of obtaining an incombustible product is not achieved with nitrocelluloses.



   The new product is not flammable even in the thinnest platform. When exposed to a flame in the usual thickness of a film, the product melts in the overheated area, but only there, without even showing the appearance of a flame.



   So it is a material created that in every respect, such. B. Transparency,
Elasticity and tensile strength, malleability in warmth, ability to color, blow-out ability, etc., which is equivalent to ordinary celluloid, but is neither flammable nor explosive. The new product is an absolutely harmless body, neither in its manufacture nor in its processing, e.g. B. to film, printing blocks, utensils, etc., can cause personal injury or material damage.
