Description

Titansäurehaltige Anstrichfarbe Die unter Verwendung von Titansäure hergestellten Farben sind bekanntlich hinsichtlich Deckkraft und Widerstandsfähigkeit gegenüber chemischen Einflüssen den besten anderen Farben gleichzustellen oder sogar überlegen. Indessen weisen die bisherigen Titanfarben den schwerwiegenden 'Übelstand relativ geringer Haltbarkeit im Außenanstrich auf. Solche Anstriche zeigen nach verhältnismäßig kurzer Zeit die unerwünschte Erscheinung des Abkreidens, so daß sie Bleiweißanstriche, welche größere Haltbarkeit aufweisen, bisher nicht vollwertig ersetzen konnten.Paint containing titanic acid Die using titanic acid manufactured colors are known for their opacity and resistance to equate or even to equate the best other colors with regard to chemical influences think. However, the previous titanium colors show the serious 'evil' relatively low durability in the exterior paint. Such paints show up relatively short time the undesirable appearance of chalking, so that white lead paints, which have greater durability, have not yet been fully-fledged could replace.

Es würde nun gefunden, daß Anstriche solcher Titansäure enthaltenden Farben eine bedeutend bessere Haltbarkeit zeigen, die einen Gehalt an kristallwasserhaltigem Bariumoxydhydrat aufweisen.It has now been found that paints containing such titanic acid Colors that have a content of water of crystallization show a significantly better durability Have barium oxide hydrate.

Zur Herstellung der titansäurehaltigen Farbstoffe, die als Grundlage für die titansäurehaltigen Farben dienen, wird beispielsweiseTitansäure mit einer verhältnismäßig geringen Menge kristallwasserhaltigem Bariumoxydhydrat (z. B. mit i o"/" Ba (OH) . # 8 H;0) gemischt. Bei titansäurehaltigen Kompositionsfarbstoffen kann der Zusatz an kristallwasserhaltigem Bariumoxydhydrat vor oder nach Zumischung der übrigen Farbstoffkomponenten erfolgen. Der Zusatz kann gegebenenfalls auch erst beim Anreiben mit Ü1 erfolgen. Anstrichfarben mit dem der Erfindung gemäßen Zusatz an kristallwasserhaltigem Bariumoxydhydrat zeigen im Außenanstrich eine sehr erheblich höhere Haltbarkeit als titansäurehaltige Anstrichfarben mit dem bisher gebräuchlichen Zusatz von Bariumsulfat. So ergaben beispielsweise Versuche mit Anstrichproben, die in den Schweizer Hochalpen unter schärfsten äußeren Bedingungen ausgelegt wurden, daß die mit Bariumsulfat allein verschnittenen Titansäurefarben sowohl auf Holz als auf Eisen schon nach q. bzw. 3 Wochen Schädigungen im Anstrich aufwiesen, während die mit mindestens 5 °1o kristallwasserhaltigem Bariumoxydhydrat versetzten Titansäurefarbstoffe im Anstrich nach iawöchiger Beobachtung noch völlig gesund erschienen. Diese die Haltbarkeit verlängernde Wirkung des kristallwasserhaltigen Bariumoxydhydrats ist um so überraschender, als normales Bariumhydroxyd gegenüber Bariumsulfat keine Erhöhung der Haltbarkeit von damit zubereiteten Farben aufweist.For the production of the titanium acid-containing dyes, which are used as the basis for the paints that contain titanium acid, for example, titanium acid is mixed with a relatively small amount of barium oxide hydrate containing water of crystallization (e.g. with i o "/" Ba (OH). # 8 H; 0) mixed. For composition dyes containing titanium acid The addition of barium oxide hydrate containing water of crystallization can be added before or after admixing the remaining dye components take place. The addition can also be added first when driving with Ü1. Paints with the additive according to the invention of barium oxide hydrate containing water of crystallization show a very considerable in the exterior paint higher durability than paints containing titanium acid with the previously common ones Addition of barium sulfate. For example, tests with paint samples which were laid out in the Swiss High Alps under the harshest external conditions, that the titanium acid paints mixed with barium sulfate alone both on wood than on iron already after q. or 3 weeks showed damage in the paint, during the titanic acid dyes mixed with at least 5 ° 1o of barium oxide hydrate containing water of crystallization appeared completely healthy in the paint after ia week's observation. This the The effect of the water of crystallization barium oxide hydrate is to extend the shelf life all the more surprising, as normal barium hydroxide does not increase compared to barium sulfate the durability of paints prepared with it.
