Description
Verfahren zur Herstellung von Anstrichfarben. Für Anstrichzwecke verwendet man vielfach die unter dem Namen von Mennige bekannte Bleioxydverbindung. Wenn man diesen Stoff mit Öl verreibt, so zeigt die Farbmischung die Neigung, sich zu entmischen. Das ist sowohl für den Anstrichprozeß selbst insofern nachteilig, als die Bindung des Öls mit dem Farbkörper nicht innig genug ist, um ein Ablaufen des Öls von dem Farbkörper mit Sicherheit auszuschließen, als auch beim Aufbewahren der fertigen Farbe sich leicht ein Kuchen unter der klaren Ölschicht absetzt, der in kurzer Zeit hart wird.Process for the production of paints. Used for painting purposes one often uses the lead oxide compound known under the name of red lead. If rubs this substance with oil, the color mixture shows the tendency to separate. This is detrimental to both the painting process itself and the bond of the oil is not intimate enough with the color body to cause the oil to run off the Exclude color bodies with certainty, as well as when storing the finished Color a cake easily settles under the clear layer of oil, which in a short time gets hard.
Gemäß vorliegender Erfindung werden die Schwierigkeiten, welche sich der Gewinnung einer Anstrichfarbe mit Bleioxyd als Basis entgegensetzen, vermieden durch die Anwendung eines Bleioxyds besonderer Art, nämlich eines Bleioxyds, welches aus in einem gasförmigen Medium suspendiertem Dampf durch Verdichtung des Dampfes zu Rauch und darauffolgende Niederschlagung des Rauches durch geeignete Niederschlagsmittel, wie z. B. durch Filtration oder Auswaschung oder durch hochgespannten elektrischen Strom, niedergeschlagen wird. Der Dampf kann durch hohe Erhitzung einer groberen Modifikation des Bleioxyds erzeugt werden oder auch aus metallischem Blei oder einer geeigneten Bleiverbindung unter Umsetzung zu Bleioxyd, sei es vor oder nach Überführung in den Dampfzustand.According to the present invention, the difficulties which arise oppose the production of a paint with lead oxide as a base, avoided through the use of a special kind of lead oxide, namely a lead oxide, which from vapor suspended in a gaseous medium by compressing the vapor to smoke and the subsequent suppression of the smoke by suitable means of precipitation, such as B. by filtration or leaching or by high voltage electrical Electricity being knocked down. The steam can be increased by heating a coarse Modification of lead oxide can be generated or from metallic lead or a suitable lead compound with conversion to lead oxide, be it before or after conversion in the steam state.
Das auf die vorstehend angegebene Weise gewonnene Bleioxyd, welches sich in einem Zustande feinster Verteilung befindet, ergibt beim Zerreiben mit einem Bindemittel, wie 01 o. dgl., eine Farbe von außerordentlicher Deckkraft, welche in dieser Hinsicht der Mennige weit überlegen ist.The lead oxide obtained in the above-mentioned manner, which is in a state of extremely fine distribution, gives, when rubbed with a binder such as oil or the like, a color of extraordinary covering power, which in this respect is far superior to red lead.
Wenn man dieser Farbe für die Erzeugung der meist gewünschten, etwas dunkleren Anstriche in üblicher Weise etwas Kienruß in einer Menge von etwa 3 Prozent zusetzt, dann ist ihre Deckkraft etwa doppelt so groß wie die von Mennige.If you can use this color for generating the most desired, something darker paints in the usual way some pine soot in an amount of about 3 percent adds, then their opacity is about twice as great as that of red lead.
Für gleiche Deckkraft des Anstrichs beträgt z. der Anspruch an Farbkörper beim dispersen Bleioxyd x, bei Mennige 5, 2. das Verhältnis des Ölverbrauchs der beiden Vergleichsfarben z : o,8, 3. das Verhältnis der Farbmischung (Öl und Farbkörper) z : 2,9.For the same covering power of the paint z. the demand on color bodies for disperse lead oxide x, for red lead 5, 2. the ratio of oil consumption of two comparison colors z: o, 8, 3. the ratio of the color mixture (oil and color body) z: 2.9.
Die vergleichenden Feststellungen hinsichtlich Trockendauer, Elastizität, Verhalten gegen Erhitzen, Witterungsbeständigkeit und Sonnenbestrahlung ergaben desgleichen mindestens Gleichwertigkeit mit Mennigeanstrich.The comparative findings regarding drying time, elasticity, Behavior against heating, weather resistance and solar radiation showed likewise at least equivalence with red lead paint.
