Description
Verfahren zum Lichtechtmachen von Lithopon. Patentiert im Deutschen Reiche vom 10. Oktober 1906 ab. Process for rendering lithopon lightfast. Patented in the German Empire on October 10, 1906.
Lithopon, das bekanntlich durch Fällen von Zinksalzen mit Schwefelverbindungen der alkalischen Erden und Alkalien und Glühen des erhaltenen Niederschlages gewonnen wird, besitzt die Eigenschaft, unter gewissen Umständen durch Sonnenlicht seine Farbe zu verändern.Lithopon, which is known by precipitating zinc salts with sulfur compounds of the alkaline Earth and alkalis and glow of the precipitate obtained is obtained, has the property under certain circumstances to change color through sunlight.
Man hat nun auf verschiedenste Weise versucht, diese sehr nachteilige Eigenschaft zuAttempts have now been made in various ways to achieve this very disadvantageous property
ίο beseitigen, z. B. durch Behandeln des Lithopons mit Superoxyden oder durch Vermischen mit wasserlöslichen Natron- oder Kalisalzen. Nach allen, bisher bekannten Verfahren ist es jedoch nicht gelungen, ein Lithopon herzustellen, das als wirklich lichtecht bezeichnet werden könnte.ίο eliminate, e.g. B. by treating the lithopon with super oxides or by mixing with water-soluble sodium or potassium salts. However, according to all previously known methods it has not been possible to produce a lithopone, that could be described as really lightfast.
Das nach vorliegendem Verfahren hergestellte Lithopon besitzt dagegen diese wertvolle Eigenschaft. Es enthält ferner keine Stoffe, die das Bindemittel des Lithopone verändern, wie die Superoxyde oder solche Substanzen, die nach dem Anstrich durch Witterungseinflüsse — Regen ■;— entfernt werden oder das Vermischen mit anderen Farben oder mit Lacken ungünstig beeinflussen.The lithopone produced according to the present process, on the other hand, has this valuable Characteristic. Furthermore, it does not contain any substances that change the binding agent of the Lithopone, like the super oxides or those substances that are exposed to the effects of the weather after painting - Rain ■; - to be removed or mixing with other colors or have an unfavorable effect with paints.
Ein weiterer Vorteil des nach vorliegendem Verfahren hergestellten Lithopons besteht darin, daß es ähnlich wie Bleiweiß sehr wenig öl aufnimmt.Another advantage of the lithopone produced by the present process is there in that, like white lead, it absorbs very little oil.
Das Verfahren besteht darin, daß man der gewöhnlichen, lichtunechten Ware in irgend-35 The procedure consists in that the ordinary, light-impervious goods are in some form of 35
einem Stadium der Fabrikation nach dem Glühen, also auch dem fertigen Handelsprodukt, oder dem Bindemittel des Lithopons Seifen der. alkalischen Erden oder des Aluminiums zusetzt. Diese Seifen gibt man entweder in fertigem Zustande zu dem Lithopon oder dem Bindemittel oder man bringt das Lithopon mit gewöhnlicher Seifenlösung in Berührung und schlägt in dieser Mischung die genannten unlöslichen Seifen nieder oder stellt diese aus den Oxyden der betreffenden Metalle mit Hilfe des Bindemittels her. Die für den vorliegenden Zweck geeignetsten Seifen sind die Magnesiaseifen, von denen geringere Mengen erforderlich sind, um die bestmögliche Wirkung zu erzielen, als von den übrigen.a stage of manufacture after annealing, including the finished commercial product, or the binder of the lithopone soaps. alkaline earths or aluminum clogs. These soaps are either added in the finished state to the lithopone or the binding agent, or they are brought Lithopon comes into contact with ordinary soap solution and beats in this mixture the above-mentioned insoluble soaps or represents them from the oxides of the relevant Metals with the help of the binder. The most suitable soaps for the present purpose are the magnesia soaps, smaller amounts of which are required to make the best possible To achieve effect than from the rest.
Beispiel: 20 kg Leinöl erhitzt man mit 3 kg Ätzkalk etwa 1 Stunde bei 150 bis i6o° unter beständigem Umrühren. Darauf verreibt man dieses Gemisch mit 100 kg Lithopon. Example: 20 kg of linseed oil are heated with 3 kg of quicklime for about 1 hour at 150 to 160 ° with constant stirring. This mixture is then rubbed in with 100 kg of Lithopon.
