Abstract
Description
Die Erfindung bezieht sich auf anorganische Korrosionsschutz-Pig mente, bestehend aus oberflächenbeschichteten feinteiligen Festkörpern mit einer Korngröße von 0,1 bis 75 µm, vorzugsweise 0,2 bis 10 µm, ein Verfahren zu deren Herstellung und deren Verwendung.The invention relates to inorganic corrosion protection pig elements consisting of surface-coated fine particles Solids with a grain size of 0.1 to 75 microns, preferably 0.2 to 10 µm, a process for their preparation and their Use.
Anorganische Füllstoffe sind in feinteiliger Form vorliegende Festkörper, die sich von anorganische Weißpigmenten durch ihre Brechzahl unterscheiden. Füllstoffe haben in der Regel Brechzahlen < 1.7 (gegen Vakuum), Weißpigmente größere. Ein weiteres Unterscheidungsmerkmal ist darin zu sehen, daß diese Materialien der Füllung dienen, also in der jeweiligen Mischung einen Hauptbestandteil darstellen. Pigmente werden dagegen überwiegend in geringen Mengen verwendet. Beide Abgrenzungskriterien sind jedoch nicht exakt; denn einerseits kann auch ein Füllstoff mit einer Brechzahl von < 1.7 in einer geeignet gewählten Matrix ein gewisses Deckvermögen, also eine eigentlich pigmentspezifische Eigenschaft besitzen, andererseits werden auch bestimmte Füllstoffe nur in kleinen Mengen eingesetzt. Die Grenze ist also fließend.Inorganic fillers are in finely divided form Solids that differ from inorganic white pigments through their Differentiate refractive index. Fillers usually have Refractive indices <1.7 (against vacuum), white pigments larger. On Another distinguishing feature can be seen in the fact that this Filling materials are used, i.e. in the respective mixture constitute a major component. Pigments are opposed mainly used in small quantities. Both Delimitation criteria, however, are not exact; because on the one hand can also be a filler with a refractive index of <1.7 in one suitably chosen matrix a certain opacity, i.e. a actually have pigment-specific properties, on the other hand, certain fillers are only used in small amounts Amounts used. So the line is fluid.
Füllstoffe haben zwei Aufgaben; einmal sollen sie im klassischen Sinne ein Produkt verbilligen und dafür sorgen, daß es im Vergleich zu ungefüllten Produkten verbesserte bzw. zusätzliche neue Eigenschaften aufweist, zum anderen soll die Verwendung von Füllstoffen häufig die Herstellung von Produkten erleichtern.Fillers have two functions; once in the make a product cheaper in the classic sense and ensure that it improved or compared to unfilled products has additional new properties, on the other hand, the Use of fillers often in the manufacture of products facilitate.
Neben der kostensenkenden Wirkung haben Füllstoffe auch noch Einfluß auf die Rheologie, d. h. Verdickung und ggf. Thixotropierung durch gezielte Einstellung einer zeitabhängigen Strukturviskosität, z. B. durch Talk, Wollastonit und Kaolin. Allgemein soll das Fließverhalten bei Lacken, Beschichtungen, Druckfarben, flüssigen Kunststoffen und Dichtungsmassen beeinflußt werden. Durch Füllstoffe werden auch die optischen Eigenschaften beeinflußt, z. B. werden Weißgrad und Deckvermögen bei Ersatz des echten Weißpigments durch u. a. synthetische Silikate in Dispersionsfarben verbessert. Durch die Verwendung von Glimmer-, Eisenglimmer- und Bariumsulfat-Füllstoffen läßt sich der Korrosionsschutz von Anstrichen und Beschichtungen gegen Witterungseinflüsse und Chemikalien verbessern.In addition to the cost-reducing effect, fillers also have Influence on rheology, d.
