Description

Anstrichmittel Es sind Anstrichmittel bekannt, die aus einem flüssigen Bestandteil, nämlich einer wäßrigen Lösung von Magnesiumchlorid, und aus einem festen Bestandteil, nämlich einer Mischung von Magnesiumoxyd und Pigmenten, bestehen. Als Pigmente verwendet man hierfür des öfteren Titandioxyd und gegebenenfalls auch Bariumsulfat.Paints There are paints known, which consist of a liquid Constituent, namely an aqueous solution of magnesium chloride, and a solid Constituent, namely a mixture of magnesium oxide and pigments. as Pigments are often used for this purpose, titanium dioxide and, if necessary, barium sulfate.

Es wurde nun gefunden, daß ein Zusatz von Thoriumsulfat zu einem Anstrichmittel, das Magnesiumchlorid, Magnesiumoxyd, Titandioxyd und Wasser sowie gegebenenfalls Bariumstilfat und bzw. oder andere Pigmente enthält, einem mit einem solchen Anstrichmittel -hergestellten Anstrichfilm überraschend günstige Eigenschaften, insbesondere hinsichtlich Dauerhaftigkeit und Beständigkeit 'gegenüber Hitze und Feuchtigkeitseinflüssen, verleiht.It has now been found that an addition of thorium sulfate to a paint, the magnesium chloride, magnesium oxide, titanium dioxide and water as well as optionally Contains barium stilfate and / or other pigments, one with such a paint -Produced paint film surprisingly favorable properties, especially with regard to Durability and resistance to heat and moisture, confers.

Die überraschende Wirkung eines Zusatzes von Thoriumsulfat zu solchen Anstrichmitteln geht z. B. aus nachfolgendem Vergleichsversuch hervor. Man stellt die beiden folgenden pulverförmigen Mischungen her: Mischung A: M90 ..... 7a Gewichtsprozent, SiO. .....i3 _ TiO2 ..... i - - BaS04 .... 1q. - Mischung B: Mg0 ..... 72 Gewichtsprozent, SiO2 .....r3 - TiO. ..... z = Th (S04)2 , iq. - Man läßt darauf die verformte Masse während etwa drei Wochen trocknen und taucht dann die beiden Proben z.. Stunden in Wasser, welches man heiß erhält. Man stellt dann fest, daß die Masse A sich .völlig zersetzt, während die Masse B unverändert bleibt.The surprising effect of adding thorium sulfate to such paints is such. B. from the following comparative experiment. The following two powder mixtures are made: Mixture A: M90 ..... 7a weight percent, SiO. ..... i3 _ TiO2 ..... i - - BaS04 .... 1q. - Mixture B: Mg0 ..... 72 percent by weight, SiO2 ..... r3 - TiO. ..... z = Th (S04) 2, iq. - The shaped mass is then allowed to dry for about three weeks and the two samples are then immersed for two hours in water which is obtained hot. It is then found that the mass A completely decomposes, while the mass B remains unchanged.

Worauf diese überraschend vorteilhafte Wirkung eines Zusatzes von Thoriumsulfat zurückzuführen ist, hat der Erfinder trotz eingehender Versuche bisher noch nicht mit Sicherheit zu klären vermocht: Um den Nachteil zu vermeiden, claß das Anstrichmittel im Augenblick der Verwendung mittels einer Mahlvorrichtung zübereitet werden muß, ist es auch möglich, die pulverförmigen Anteile in Gestalt einer stabilen Paste zu benutzen, die man nur im Augenblick der Verwendung mit dem flüssigen Bestandteil, d. h. mit der Magnesiumchloridlösung, zu verdünnen braucht.What this surprisingly beneficial effect of an addition of Thorium sulfate is due, the inventor has so far despite extensive experiments has not yet been able to clarify with certainty: To the disadvantage too Avoid leaving the paint at the moment of use by means of a grinder Must be prepared, it is also possible to shape the powdery fractions a stable paste that can only be used with the liquid component, d. H. with the magnesium chloride solution.

Zu diesem Zweck wird die pulverförmige Mischung, wie sie oben gekennzeichnet worden ist, mit .einer hydrophilen organischen, vorzugsweise flüchtigen, mit den Bestandteilen der Mischung sich nicht umsetzenden Flüssigkeit zu einem Teig oder einer Paste ver- -mahlen; beispielsweise wird man hierfür sulfonierte Fettalkohole, niedermolekulare Mono-oder Polyalkohole - und ihre Derivate verwenden oder eine wäßrige Suspension der pulverförmigen Bestandteile benutzen, die Schutzkolloide enthält, wie die Lisalbin- oder Protalbinsäuren oder ihre Salze oder 14Iischungen dieser verschiedenen Stoffe. Im Augenblick ihrer Verwendung wird die Paste mit dem flüssigen Bestandteil, d. h. mit der -#x"äßrigen Magnesiumchloridlösung, gemischt und durch ein Sieb gegeben.For this purpose the powdery mixture is used as marked above has been, with .einer hydrophilic organic, preferably volatile, with the Ingredients of the mixture turn into a batter or liquid that does not react grind into a paste; For example, sulfonated fatty alcohols are used for this, low molecular weight mono- or polyalcohols - and their derivatives or use one Use aqueous suspension of the powdery components, the protective colloids contains, such as the lisalbic or protalbic acids or their salts or mixtures of these different substances. At the moment of its use, the paste comes with the liquid component, d. H. with the - # x "aqueous magnesium chloride solution and passed through a sieve.

Es ist gegebenenfalls vorteilhaft, dem erfindungsgemäßen Anstrichmittel Netzmittel zuzusetzen, welche die Oberflächenspannung des Anstrichmittels herabzusetzen vermögen, "wie die Gallensäuren, Taurocholsäure oder ihre Salze. Man wird auf diese Weise das Aufbringen der Farbe auf glatte Oberflächen erleichtern.It may be advantageous to use the paint according to the invention Add wetting agents, which reduce the surface tension of the paint be able to "like the bile acids, taurocholic acid or their salts. One is on these Way to make it easier to apply the paint to smooth surfaces.
