  VerfahrenzurHerstellungvonSchildpattimitationen. 



   Gegenstand der Erfindung bildet ein Verfahren zur Herstellung von Schildpattimitationen und sonstigen flockig gefärbten Materialien aus Kondensationsprodukten der Phenole und des Formaldehyds. welches dadurch gekennzeichnet ist, dass man flüssige, gefärbte oder angefärbte Phenol-FormaldehydHarze so lange ohne Druck erhitzt, bis sie in den üblichen Lösungsmitteln teilweise   unlöslich   werden. dieselben hierauf zerkleinert und mit flüssigen, gefärbten oder ungefärbten Phenol-Formaldehyd-Harzen in Formen vergiesst und ohne Druck härtet. 



   Zur Ausführung des Verfahrens werden obgenannte Harze in flüssigem und gefärbtem oder   tin-   gefärbtem Zustande ohne Druck bei einer Temperatur von   75-90-so   lange polymerisiert. bis sie sich in den bekannten   Lösungsmitteln,   wie   Methylalkohol.   Äthylalkohol, Azeton u. dgl. nur noch teilweise lösen. 



   Die so behandelten Harze werden sodann   bis auf 20"abgekühlt,   in einem Schrottapparat zerkleinert, die Stücke gut miteinander vermengt. sodann in flachen Behältern ausgebreitet und kurze Zeit auf   40-500 erhitzt : da'Gemenge backt   hiebei zu einer   un regelmässigen   Platte zusammen   und   wird sodann im warmen Zustande in einer geeigneten Maschine in unregelmässige Stücke ungleicher   Grösse   
 EMI1.1 
 Phenol-Formaldehyd-Harzen in Formen gefüllt und ohne Druck   gehärtet.

   Die zugesetzten festen   Harzteile lösen sich, da sie auch in Alkohol, Azeton u. dgl. nur mehr   teilweise löslich sind.   in dem flüssigen Harze nicht mehr auf. sondern bilden in der erhärteten Masse scharf abgetrennte Partien, welche dem Material das Aussehen von   Schildpatt   oder sonstigem flockig gefärbten Materiale verleihen.

  Process for the production of tortoise-shell imitations.



   The invention relates to a process for the production of imitations of tortoiseshell and other flaky colored materials from condensation products of phenols and formaldehyde. which is characterized in that liquid, colored or stained phenol-formaldehyde resins are heated without pressure until they are partially insoluble in the usual solvents. these are then crushed and poured into molds with liquid, colored or uncolored phenol-formaldehyde resins and hardened without pressure.



   To carry out the process, the above-mentioned resins are polymerized in liquid and colored or ink-colored state without pressure at a temperature of 75-90 times. until they settle in known solvents like methyl alcohol. Ethyl alcohol, acetone, etc. Like. Only partially solve.



   The resins treated in this way are then cooled down to 20 ", crushed in a scrap machine, the pieces are mixed well together, then spread out in shallow containers and heated for a short time to 40-500: the amount cakes and becomes an irregular plate then in a warm state in a suitable machine into irregular pieces of unequal size
 EMI1.1
 Phenol-formaldehyde resins filled into molds and cured without pressure.

   The added solid resin parts dissolve because they are also in alcohol, acetone and the like. Like. Are only partially soluble. in the liquid resin no longer occurs. but instead form sharply separated areas in the hardened mass, which give the material the appearance of tortoiseshell or other flaky colored material.
