Description

Verfahren zur Herstellung von anorganischen Farbpigmenten Es wurde gefunden, daß man blaue Farbpigmente dadurch herstellen kann, daß man Zinkoxyd, Siliciumdioxyd und Kobaltaxyd bzw. an deren Stelle durch thermische Behandlung die entsprechenden Metalloxyde liefernde Metallverbindungen zusammen einem Glühprozeß unterwirft. Man kann bei der Herstellung dieser Pigmente auch so verfahren, daß man zunächst durch Glühen von beispielsweis:e Zinksulfat und S:iliciumdi,oxyd einen weißen Grundkörper herstellt und diesen Grundkörper nachträglich mit Kobaltsulfat innig vermischt und dann glüht.Process for the production of inorganic color pigments It was found that blue color pigments can be produced by using zinc oxide, Silicon dioxide and cobalt oxide or, in their place, by thermal treatment corresponding metal oxides supplying metal compounds together in an annealing process subject. One can also proceed in the production of these pigments in such a way that by annealing, for example: e zinc sulphate and S: iliciumdi, oxide one white base body and this base body subsequently with cobalt sulfate intimately mixed and then glows.

Je nach Art und Menge der angewendeten Grundkörper bzw. des Kobaltsalzes erhält man blaue Farbpigmente verschiedener Farbnuancen, welche sich durch hervorragende Eigenschaften, insbesondere hinsichtlich Deckkraft, Beständigkeit gegen Temperatur- und Witterungseinflüsse, Lichtechtheit und Zementbeständigkeit, auszeichnen. Beispiel Man glüht ein inniges Gemenge von 28,7 Gewichtsteilen Zn S 04 # % H2 O und I2 Gewichtsteile Si02 zur Vertreibung des S03 zwei Stunden bei etwa i ooo°. Der erhaltene weiße Grundkörper wird mit 28,1 Gewichtsteilen Co S 0, # 7 H2 O gut gemischt und erneut geglüht. Es entsteht ein schönes, sehr beständiges Blaupigment von hervorragender Deckfähigkeit.Depending on the type and amount of the base body or cobalt salt used, blue color pigments of various color nuances are obtained, which are characterized by excellent properties, in particular with regard to covering power, resistance to temperature and weathering influences, lightfastness and cement resistance. EXAMPLE An intimate mixture of 28.7 parts by weight of Zn S 04 #% H2 O and I2 parts by weight of Si02 is annealed for two hours at about 100 ° to drive off the S03. The white base body obtained is mixed well with 28.1 parts by weight of Co S 0, # 7 H2 O and re-calcined. The result is a beautiful, very permanent blue pigment with excellent hiding power.
