Chemisch beständiges, temperaturbeständiges anorganisch aufgebautes lackförmiges Anstrichmittel (Zusatz zu Patent Patentanm. P 2o 06 ο95·1)Chemically resistant, temperature-resistant, inorganically built-up paint in the form of varnishes (Addition to patent patent application P 2o 06 ο95 1)

Die Erfindung betrifft ein chemisch beständiges, temperaturbeständiges anorganisch aufgebautes lackförmiges Anstrichmittel, bestehend aus einem Bindemittel und einem Pigment, bei dem ein feinpulvriges, temperatur- und chemisch beständiges Füllmittel mit sehr kleinem linearen Wärmeausdehnungskoeffizienten in dem -Bindemittel homogen verteilt ist, und der Anteil des Füllstoffes im Anstrichmittel vorzugsweise zwischen 3o und 7o % liegt.The invention relates to a chemically stable, temperature-resistant, inorganically structured lacquer-like paint, consisting of a binder and a pigment, in which a finely powdered, temperature- and chemically-resistant filler with a very small linear thermal expansion coefficient is homogeneously distributed in the binder, and the proportion of the filler in the paint is preferably between 3o and 7o % .

Die Aufgabe der Erfindung besteht darin, ein einfach darzustellendes anorganisches Anstrichmittel zu schaffen, das bei hoher Temperaturbeständigkeit und hoher chemischer Beständigkeit einen geringen Wärmeausdehnungskoeffizienten sowie eine hohe Druckfestigkeit aufweist. Ferner soll das Anstrichmittel auch bei häufig auftretender Temperaturwechselbeanspruchung gut haften, und keine mechanische oder chemische Bindung mit anderen Werkstoffen eingehen.The object of the invention is to provide a simple to represent To create inorganic paint that has high temperature resistance and high chemical resistance has a low coefficient of thermal expansion and high compressive strength. Furthermore, the paint should Adhere well even with frequent thermal cycling, and no mechanical or chemical bond with other materials.

Die Erfindung bestellt darin, daß der Bindemittel ans at ζ aus einer wässrigen Chromsäurelösung'(2o - 3o Gewichts-% Chromsäure) besteht, der phosphorige Säure oder deren Salze (ca. 1o Gewichts-%) zugesetzt sind.The invention orders that the binder ans at ζ from an aqueous chromic acid solution '(2o - 3o% by weight chromic acid) consists, the phosphorous acid or its salts (approx. 10% by weight) are added.

Hierbei Vird ein Überschuß an Chromsäure verwendet. Ein wesentlicher Vorteil der Erfindung wird darin gesehen, daß infolge der "Verminderung der Reaktionspartner und ohne Hydroxydherstellung eine einfache Herstellung des Bindemittelansatzes möglich ist. Bei größeren Ansätzen muß die entstehende Reaktionswärme durch Kühlung abgeführt werden.An excess of chromic acid is used here. An essential one The advantage of the invention is seen in the fact that as a result of the "reduction of the reactants and without hydroxide production a simple production of the binder approach is possible. In the case of larger batches, the heat of reaction produced has to pass through Cooling can be dissipated.

Als Füllstoff dienen Quarzmehl oder andere temperaturbeständige Pigmente.Quartz powder or other temperature-resistant pigments are used as fillers.

Wird das erfindungsgemäße Anstrichmittel beispielsweise mittels einer Farbspritzpistole auf das Grundmaterial aufgetragen, entweicht vorerst ein geringer Wasseranteil durch. Verdunsten. Das restliche Verdampfen des Wassers aus dem Anstrichmittel wird durch ein etwa halbstündiges Erwärmen auf 80 bis 9o° C erreicht, wobei jede Blasenbildung vermieden wird. Nach dieser Wärmelagerung kann das etwa halbstündige Einbrennen bei 25o - 35o° C erfolgen.If the paint according to the invention is applied to the base material, for example by means of a paint spray gun, it escapes initially a low water content. Evaporate. The remaining water will evaporate from the paint achieved by heating to 80 to 90 ° C for about half an hour, avoiding any blistering. After this heat storage, it can be stoved for about half an hour at 25o - 35o ° C take place.

Da die so entstehende Schicht neben guter Korrosionsbeständigkeit, Temperaturbeständigkeit ca. 9oo° C, einer guten Haftung aufSince the resulting layer is not only good corrosion resistance, Temperature resistance approx. 900 ° C, good adhesion

metallischen und keramischen Grundmaterialien, einem geringen Wärmeausdehnungskoeffizienten auch eine sehr hohe Druckfestigkeit aufweist, findet das erfindungsgemäße Anstrichmittel "beispielsweise als Trennmittel zum Auskleiden von Gießformen Anwendung. Da es hierbei wegen seiner annähernd unbegrenzten Lebensdauer beliebig oft verwendbar ist, braucht das Anstrichmittel nur einmal auf die Formfläche aufgetragen und eingebrannt werden.metallic and ceramic base materials, a small amount The paint according to the invention also has a very high compressive strength coefficient of thermal expansion "For example, as a release agent for lining casting molds can be used as often as required for an unlimited service life, the coating material only needs to be applied once on the mold surface applied and baked.
