Abstract
Description
Die Erfindung betrifft die Herstellung farbiger Metalleffektpigmente für Bronzierungen, Druck- und Lackfarben.The invention relates to the production of colored metallic effect pigments for bronzing, printing and Paint colors.
Effektpigmente in verschiedenen Farbtönen wie z. B. Gold, Kupfer und Silber werden in Druck- und Lackfarben eingesetzt um beispielsweise Verpackungen, Flaschenetiketten und Dekorationsartikeln ein wirkungsvolles dekoratives Aussehen in verschiedenen metallischen Farbtönen zu verleihen.Effect pigments in different shades such as B. Gold, copper and silver are in printing and Paint colors used for example in packaging, bottle labels and decorative items to give an effective decorative appearance in various metallic colors.
Farbige Metalleffektpigmente werden derzeit aus Kupfer und Messing hergestellt. Hierbei wird ausgehend von Metallgranulaten durch mechanische Zerkleinerungsverfahren wie Mahlen oder Stampfen ein plättchenförmiges, glänzendes Metallpulver erzeugt.Colored metallic effect pigments are currently made from copper and brass. Here will starting from metal granules by mechanical comminution processes such as grinding or Stamping produces a platelet-shaped, shiny metal powder.
Die Farbe dieser Pulver kann durch Erzeugung von Anlauffarben auf der Metalloberfläche mittels Erhitzen gezielt verändert werden.The color of these powders can be created by producing tarnish colors on the metal surface Heating can be changed in a targeted manner.
Seit einigen Jahren werden neben den o.g. klassischen Bronzen Effektpigmente auch durch Beschichtung von Aluminium- und Glimmerpigmenten mit Substanzen wie Fe₂O₃ (1) oder TiO₂ hergestellt (2).For some years now, in addition to the above classic bronze effect pigments Coating of aluminum and mica pigments with substances such as Fe₂O₃ (1) or TiO₂ manufactured (2).
Die weitere Verwendung von Pigmenten aus Kupfer und Messing ist zunehmend in Frage gestellt, da diese aus ökologisch bedenklichen Schwermetallen bestehen.The further use of pigments from copper and brass is increasingly questioned because they consist of ecologically questionable heavy metals.
Nachteilig an beschichteten Aluminium- und Glimmerpigmenten sind der hohe technische Aufwand und die damit verbundenen Kosten bei der Aufbringung der Beschichtung. Weiterhin weichen die stofflichen Eigenschaften dieser Pigmente ( Schüttdichte, Lichtdurchlässigkeit von Glimmerpigmenten) zum Teil erheblich von denen der Bronzen aus Kupfer und Messing ab, was zu Schwierigkeiten bei bestimmten Applikationen führen kann.The disadvantage of coated aluminum and mica pigments is the high technical level Effort and the associated costs when applying the coating. Farther the material properties of these pigments (bulk density, light transmission from Mica pigments) partly significantly different from those of the bronze copper and brass, leading to Difficulties in certain applications can result.
Der Erfindung liegt die Aufgabe zugrunde, ein Metalleffektpigment herzustellen, welches die Nachteile der o.g. Pigmente vermeidet.The invention has for its object to produce a metallic effect pigment which Disadvantages of the above Avoids pigments.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß Metalleffektpigmente aus Eisen und Eisenlegierungen hergestellt werden.The object is achieved in that metallic effect pigments made of iron and Iron alloys are manufactured.
Verdüstes Eisenpulver wird durch einen mechanischen Zerkleinerungsprozeß trocken oder naß (z. B. in Wasser oder Testbenzin) unter Zugabe von Mahlhilfsmitteln zerkleinert und in Schuppen umgewandelt, wobei ein hell glänzendes silberfarbenes Pigment entsteht.Atomized iron powder becomes dry or wet through a mechanical crushing process (e.g. in water or white spirit) with the addition of grinding aids and shredded converted, creating a bright, shiny silver-colored pigment.
Durch anschließendes Erhitzen dieses Pigments in einen Temperaturbereich von ca. 200-500°C in Gegenwart von Sauerstoff entstehen, abhängig von der Höhe der erreichten Temperatur, durch Oxidation an der Oberfläche des Pigmentes Anlauffarben in den Farbtönen Gold, Rotviolett und Blau.By subsequently heating this pigment in a temperature range of approx. 200-500 ° C in The presence of oxygen is caused by, depending on the level of the temperature reached Oxidation on the surface of the pigment Tarnish colors in the shades of gold, red violet and Blue.
Neben den oben genannten entstehen weitere Farbtöne, wenn man einer Pigmentpaste geeignete, im Anteigmittel lösliche Substanzen (z. B. Kaliumpermanganat bei Verwendung von Wasser) zufügt und wie oben beschrieben erhitzt wird.In addition to the above, other shades are created when using pigment paste suitable substances soluble in the pasting agent (e.g. potassium permanganate when using Water) and heated as described above.
Die hier beschriebenen Pigmente sind physiologisch unbedenklich.The pigments described here are physiologically harmless.
Die notwendigen Rohmaterialien sind einfach und preiswert zu beschaffen.The necessary raw materials are easy and inexpensive to obtain.
Der Aufwand für die Herstellung entspricht in etwa dem klassischer Pulverbronzen.The effort for the production corresponds approximately to the classic powder bronze.
Die beschriebenen Pigmente weisen ähnliche Stoffeigenschaften wie die bisher verwendeten Pulverbronzen auf.The pigments described have similar material properties to those previously used Powder bronzes.
Bei der Herstellung kann auf vorhandene Technologien zurückgegriffen werden.Existing technologies can be used during production.
