Description

Verfahren zur Herstellung von auf Trägersubstanzen niedergeschlagenen Farbpigmenten Die Fällung von Farbpigmenten durch Umsetzung von ungefärbten Salzen mit gefärbten Salzen in wäßriger Lösung ist bekannt. Zur Erreichung verschiedener Farbtöne werden z. B. mit Kreide, Bariumsulfat die erhaltenen Niederschläge trocken. vermahlen. Diese Pigmente haben den Nachteil, daß sie infolge ihres verschiedenen spezifischen Gewichts in den Bindemitteln sedimentieren.Process for the preparation of deposited on carrier substances Color pigments The precipitation of color pigments by converting uncolored salts with colored salts in aqueous solution is known. To achieve various Shades are z. B. with chalk, barium sulfate dry the precipitates obtained. grind. These pigments have the disadvantage that, as a result of their different specific gravity sediment in the binders.

Es wurde gefunden, daß man Farbpigmente herstellen kann, die sehr träge sedimentieren dadurch, daß man hochbasische, hydratisierte Salze, wie z. B. basisches Aluminiumsulfat, oder hochbasische Silicate oder hydratisierte Metalloxyde bzw. Metallhydroxyde mit Ionen einer Zinktetraminlösung vermischt, von der festen Substanz abpreßt und den festen Rückstand, der aus einem Adsorbat des hochbasischen, hydratisierten Salzes oder des hydratisierten Metalloxydes mit Zinktetramin besteht, in Wasser hydrolysiert.It has been found that you can produce color pigments that very sediment sluggishly by using highly basic, hydrated salts, such as. B. basic aluminum sulfate, or highly basic silicates or hydrated metal oxides or metal hydroxides mixed with ions of a zinc tetramine solution, from the solid Squeezes off the substance and removes the solid residue from an adsorbate of the highly basic, composed of hydrated salt or hydrated metal oxide with zinc tetramine, hydrolyzed in water.

Da beide Komponenten durch starke Adsorptionskräfte zusammengehalten werden und infolge der durch dipolare Gruppen ausgelösten Schwebekräfte wird eine Sedimentation im polaren Bindemittel stark verzögert.Because both components are held together by strong adsorption forces and as a result of the floating forces triggered by dipolar groups, a Sedimentation in the polar binder is greatly delayed.

Durch die Adsorption des Zinkhydroxydes an den hydratisierten Oberflächen der Trägersubstanzen wird außerdem eine Kristallisation des Zinkhydroxydes verhindert. Dies hat den Vorteil, daß das Zinkhydroxyd zur Umsetzung mit anderen Salzen mit gefärbten Anionen, z. B. Kaliumbichromat, Kaliumchromat fähig ist.Through the adsorption of the zinc hydroxide on the hydrated surfaces of the carrier substances, crystallization of the zinc hydroxide is also prevented. This has the advantage that the zinc hydroxide to react with other salts with colored anions, e.g. B. potassium dichromate, potassium chromate is capable.

Nach dem neuen Verfahren lassen sich durch Kombination der verschiedenen Komponenten im Farbton abgestufte Pigmente herstellen. An Stelle der Salze mit gefärbten Anionen können zum Teil oder ganz auch saure organische Farbstoffe, wie z. B. Alizarin, treten.According to the new process, by combining the various Manufacture components of graded pigments. Instead of some or all of the salts with colored anions can also be acidic organic Dyes such as B. Alizarin.

Die nach dem Verfahren gemäß der Erfindung hergestellten Pigmente eignen sich, da ihre Korngröße kolloidchemische Dimensionen hat, und sie sich infolge der ihnen eigenen Schwebekräfte daher leicht dispergieren lassen, in hervorragender Weise auch als Füllstoffe fürKautschuk und Kunststoffe.The pigments produced by the process according to the invention are suitable because their grain size has colloid-chemical dimensions, and they are as a result therefore allow their own suspension forces to be easily dispersed, in excellent Also as fillers for rubber and plastics.
