Verfahren zur Herstellung von weiss gefärbten Kunstmassen.
Die meisten Verfahren zur Herstellung weisser Phenolaldehyd-Kondensationsprodukte als Elfen- beinersatz zeigen den Übelstand, dass gleichmässig reinweiseFärbungen nicht hervorgerufen werden können, sondern die Färbung immer einen Stich ins Gebliche besitzt. Gemäss der Erfindung wird dieser Übelstand dadurch beseitigt, dass als Weissfärbungsmittel kolloidale, wässerige Lösungen benützt werden, die entweder an sich weiss sind oder bei der Koagulation weiss werden. Bei Ausführung des Verfahrens wird den noch löslichen, plastischen Kunstharzmassen nach Entfernung der überschüssigen Reaktionskomponenten (Formaldehyd und Phenol) sowie des Wassers vor der Härtung das als Färbemittel dienende Hydrosol zugesetzt.
Als Färbemittel können sowohl kolloidale anorganische, als auch kolloidale organische Verbindungen benützt werden, z. B. Hydrosole des Thorium-oder Zirkoniumhydroxyds, kolloidale Eiweissverbindungen wie Milch u. dgl., die an sich weiss gefärbt sind, oder bei der Koagulation einen weissen Körper zu geben vermögen.
1. Beispiel :
100 Teile des in bekannter Weise von Phenol, Formaldehyd und Wasser befreiten, dickflüssigen, durchsichtigen Zwischenkondensationsproduktes, werden innig mit mindestens 10 Teilen einer nach den
EMI1.1
lösung durchgearbeitet, worauf in bekannter Weise gehärtet wird.
IL Beispiel :
100 Teile des in Beispiel 1 beschriebenen Kondensationsproduktes werden mit mindestens 10 Teilen Milch gut durchgearbeitet, worauf die Mischung der Härtung zugeführt wird.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung weisser Kunstmassen aus Phenolaldehydkondensationsprodukten, dadurch gekennzeichnet, dass Phenolaldehyd-Zwischenkondensationsprodukte mit kolloidalen Lösungen, die an sich weiss sind oder bei der Koagulation weisse Körper ausscheiden, als Färbemittel vermischt werden und die Mischung in der üblichen Weise gehärtet wird.

Process for the production of white colored artificial masses.
Most processes for the production of white phenolaldehyde condensation products as ivory substitutes show the disadvantage that uniformly pure colors cannot be produced, but the color always has a tinge of whiteness. According to the invention, this deficiency is eliminated by using colloidal, aqueous solutions as whitening agents, which are either white per se or become white during coagulation. When carrying out the process, the still soluble, plastic synthetic resin masses are added to the hydrosol, which serves as a coloring agent, after the excess reaction components (formaldehyde and phenol) and the water have been removed before curing.
Both colloidal inorganic and colloidal organic compounds can be used as coloring agents, e.g. B. hydrosols of thorium or zirconium hydroxide, colloidal protein compounds such as milk and. Like. Which are colored white per se, or are able to give a white body during coagulation.
1st example:
100 parts of the viscous, transparent intermediate condensation product freed from phenol, formaldehyde and water in a known manner, are intimately mixed with at least 10 parts of one after the
EMI1.1
solution worked through, which is then cured in a known manner.
IL example:
100 parts of the condensation product described in Example 1 are worked through well with at least 10 parts of milk, whereupon the mixture is subjected to hardening.
PATENT CLAIMS:
1. A process for the production of white synthetic compositions from phenolaldehyde condensation products, characterized in that phenolaldehyde intermediate condensation products are mixed with colloidal solutions, which are white per se or which excrete white bodies during coagulation, as a coloring agent and the mixture is hardened in the usual way.
