KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Als Lackbildner hat man bereits Aluminiumhydrat oder auch Aluminiumsilikat benutzt. Es hat sich nun gezeigt, daß für diesen Zweck auch künstlich, durch Fällung löslicher Ma-Aluminum hydrate or aluminum silicate has already been used as a lacquer former. It has now been shown that for this purpose also artificially, by precipitation of soluble materials
. 5 gnesiumsalze, insbesondere Magnesiumsulfat hergestelltes Magnesiumsilikat verwendbar ist. Auch hat dieses vor den genannten Lackbildnern noch erhebliche Vorteile voraus, die in seiner chemischen Eigenart begründet sind.. 5 magnesium salts, especially magnesium sulfate Magnesium silicate is usable. This also has significant advantages over the paint formers mentioned are based on its chemical character.
ίο Diese ermöglicht es in erster Linie, zur Darstellung der Lacke in weitestgehendem Maße basische Farbstoffe, Methylviolett, Viktoriablau, Diamantgrün usw. zu benutzen, die sich auf diesem Lackbildner, ohne die bei dem Aluminiumoxyd enthaltenden Lackbildnern erforderlichen, die Fabrikation erheblich verteuernden Fällungsmittel, wie Tannin, Brechweinstein usw., glatt fixieren lassen. Letztere Fällungsmittel sind auch bei einem bekannten Verfahren, wonach Farblacke aus basischen Farbstoffen und Aluminiumsilikat als Lackbildner bereitet werden, für eine hinreichende Fixierung dieser Farbstoffe nicht ganz zu entbehren, wenn auch dieses Verfahren eine beträchtliche Ersparnis an diesen teuren Materialien ermöglicht.ίο This primarily allows for representation of the paints to the greatest possible extent basic dyes, methyl violet, Victoria blue, Diamond green etc. to use, which are based on this lacquer former, without the aluminum oxide containing lacquer formers required, making manufacture considerably more expensive Let precipitants such as tannin, emetic tartar, etc., set smoothly. The latter precipitants are also in a known process, according to which color lakes from basic dyes and aluminum silicate can be prepared as a lacquer former, for a sufficient fixation of these Dyes cannot be completely dispensed with, even if this process is a considerable saving made possible by these expensive materials.
Die Fixierung' basischer Farbstoffe durchThe fixation of basic dyes by
Magnesiumsilikat geht so weit, daß es sogar möglich ist, stark mit Farbstoff übersättigte Lacke herzustellen, die, auf Hochglanz gestoßen, den Metallüster feinster Blauholzbronzen übertreffen und an Preiswürdigkeit mit diesen konkurieren können, während bisher die wohl dreimal so hohen Gestehungskosten von anderweitig, ausschließlich aus Anilinfarben, bereiteten Bronzelacken ihre praktische Anwendung von vornherein ausschloß. Außer den basischen sind aber auch die sauren, zur Farblackbebereitung verwendeten Farbstoffe bei Anwendung von Magnesiumsilikat geeignet. Sie alle ergeben Lacke, die reine Nuancen, Färbtiefe und Feuer aufweisen. Gerade dieses vorzügliche Ergebnis war aber keineswegs vorauszusehen. Denn es ist bekannt, daß die . Lacke eine schmutzig-trübe Nuance ohne jedes Feuer und mit stark beeinträchtigter Färbkraft erhalten, sobald in einem Ansatz versehentlich beim Zugeben des Farbstoffs und Ausfällen desselben auf Aluminiumhydrat oder '■ Aluminiumsilikat kein Aluminiumsulfat mehr in Lösung war, d. h. also keine saure Reaktion bestand. Auch die doppelte Farbstoffmenge würde in diesem Falle dem Lacke nicht zu der in saurer' Lösung entstehenden Farbtiefe und Feuer verhelfen. Gleiches war zu er warten, wenn in der weiter unten zu beschreibenden Weise aus Magnesiumsulfat mittels Natriumsilikates das Magnesiumsilikat niedergeschlagen wird. Einmal bleibt auch bei langsamster Fällung unvermeidlich in dem gallertartigen Niederschlage etwas von dem alkalischen Fällungsmittel eingeschlossen, das erst allmählich diffundiert, zum andern aber entsteht neben dem Magnesiumsilikat freies Magnesiumhydroxyd und Magnesiumkarbonat. Es tritt daher bei der Fällung eine geringe alkalische, Phenolphthalein rötende Reaktion auf. Außerdem ist im vorliegenden Falle an Stelle des hydrolytisch stark gespaltenen Aluminiumsulfates das viel weniger dissociierte Magnesiumsulfat im Ansätze, überschüssig in Lösung.Magnesium silicate goes so far that it is even possible to be highly oversaturated with dye To produce lacquers that, when they come up to a high gloss, surpass the metal chandelier of the finest blue wood bronzes and can compete with these in terms of value for money, while so far the probably three times as high production costs as otherwise, exclusively from aniline dyes Bronze paints excluded their practical application from the outset. Except for the basic ones but also the acidic dyes used for color lacquer preparation are used of magnesium silicate. They all result in varnishes, the pure nuances, depth of color and show fire. However, it was precisely this excellent result that was by no means foreseeable. Because it is known that the . Paint a dirty, cloudy shade without any fire and with greatly impaired coloring power received once in a batch accidentally when adding the dye and Precipitation of the same on aluminum hydrate or aluminum silicate, no more aluminum sulfate was in solution, d. H. so there was no acidic reaction. Also twice the amount of dye In this case, the paint would not match the depth of color that occurs in an acidic solution and help fire. The same was to be expected when in the below to be described The magnesium silicate is precipitated from magnesium sulfate by means of sodium silicate will. Once, even with the slowest precipitation, it inevitably remains in the gelatinous Precipitate some of the alkaline precipitating agent included, which only gradually diffuses, but on the other hand, free magnesium hydroxide is formed in addition to the magnesium silicate and magnesium carbonate. There is therefore a slight alkaline, Phenolphthalein reddening reaction to. In the present case, instead of the hydrolytically strongly split aluminum sulphate is the much less dissociated magnesium sulphate in the beginning, excess in solution.
Daß trotzdem schöne, feurige Lacke erhalten werden, kann somit nur der Eigenart, der entstandenen Verbindung zugeschrieben werden. Als wichtiger technischer Effekt des vorliegenden Verfahrens verdient noch hervorgehoben zu werden, daß es danach möglich ist, an Stelle des verhältnismäßig teuren Aluminium-. sulfates das in unbegrenzten Mengen zur Verfügung stehende, bedeutend billigere' Magnesiumsulfat oder das gleichfalls nahezu wertlose Magnesiumchlorid zu verwenden.That beautiful, fiery lacquers can nevertheless be obtained can only be due to the peculiarity, the resulting connection can be attributed. As an important technical effect of the present Procedure deserves to be emphasized that it is then possible instead of the relatively expensive aluminum. sulfates that are available in unlimited quantities standing, significantly cheaper 'magnesium sulphate or the likewise almost worthless one Use magnesium chloride.
Als Ausgangsmaterialien zur Darstellung des Magnesiumsilikates dienen Magnesiumchlorid
oder -sulfat und Natriumsilikat.
Da ein Magnesiumsilikat' mit großem Überschuß an Kieselsäure, wie es durch einfache
Umsetzung mit dem käuflichen Natriumsilikat (Wasserglas) erhalten wird, nicht wünschens-
: wert ist, muß dem Wasserglas noch eine bestimmte Menge Alkali zugefügt werden. Man
richtet diesen Zusatz so ein, daß nur ein schwachsaures Silikat entsteht.Magnesium chloride or sulfate and sodium silicate are used as starting materials for the preparation of the magnesium silicate.
Since a magnesium silicate with a large excess of silica, as obtained by simple reaction with the commercially available sodium silicate (water glass), is not desirable, a certain amount of alkali must be added to the water glass. This addition is set up in such a way that only a weakly acidic silicate is formed.
160 Teile Kieserit (mit 55°/0 Mg SO^j werden in mindestens 1600 Teilen Wasser gelöst, gleichzeitig wird eine Lösung von 100 Teilen 400Z0 Wasserglas nebst 17 Teilen Ätznatron in 1000 Teilen Wasser bereitet. Letztere Lösung läßt man unter Rühren in dünnem Strahle zu der Magnesiumsulfatlösung zufließen. Hierzu gibt man dann eine 10 prozentige Lösung von 185 Teilen Chlorbarium und eine gleichfalls verdünnte Lösung von Türkischrotöl. Dann läßt man eine 1 prozentige Lösung von 12 Teilen Methyl violett B. und zum Schluß nochmals 3 Teile Türkischrotöl zufließen. Man erhält nach hinreichendem Auspressen etwa 700 Teile eines teigförmigen Farblackes.160 parts of kieserite (with 55 ° / 0 Mg SO ^ j are dissolved in at least 1600 parts of water, at the same time a solution of 100 parts of 40 0 Z 0 water glass together with 17 parts of caustic soda in 1000 parts of water is prepared. The latter solution is left in A 10 percent solution of 185 parts of chlorobarium and an equally dilute solution of Turkish red oil are then added, a 1 percent solution of 12 parts of methyl violet B. and, finally, another 3 parts of Turkish red oil. After sufficient pressing, about 700 parts of a dough-like colored varnish are obtained.
