Description

Verfahren zur Herstellung von wäßrigen Anstrichfarben In zahlreichen Verfahren hat man die Eigenschaften und die Wirkungsweise des sogenannten Sorelzementes auf Grundlage von Mg 0 und Mg C12 Anstrichzwecken, insbesondere für Tarnung und Feuerschutz, dienstbar gemacht.Process for the production of aqueous paints In numerous processes, the properties and the mode of action of the so-called Sorel cement based on Mg 0 and Mg C12 paint purposes, in particular for camouflage and fire protection, have been made available.

Die Durchhärtung aber der Massen aus gebrannter Magnesia und Chlormagnesiumlauge nimmt für manche Zwecke zuviel Zeit in Anspruch. Auch gefährdet der Regen leicht solche noch nicht verfestigten Anstriche und wäscht sie mehr oder minder stark aus. Es wurde nun gefunden, daß die Anstrichfarben auf Grundlage des sogenannten Sorelzementes sehr gut mit den rasch erhärtenden Wasserglasfarben kombiniert werden können.The hardening of the masses of burnt magnesia and chlorine magnesium lye takes too much time for some purposes. The rain is also easy to endanger paints that have not yet solidified and washes them to a greater or lesser extent. It has now been found that the paints are based on the so-called Sorel cement Can be combined very well with the rapidly hardening water-glass paints.

Eine solche Kombination, die infolge der stattfindenden klumpigen Ausscheidung von Magnesiumsilikaten zunächst nicht möglich erscheint, die aber bei einiger Vorsicht sehr wohl bewerkstelligt werden kann, vereinigt die Vorzüge beider Anstrichmittel, nämlich die rasche Erhärtung der Wasserglasanstriche und die gute Haftfestigkeit der Sorelzementanstriche. Man muß nur darauf achten- daß die anfänglich sich bildende Ausscheidung, die leicht zusammenklumpt, durch weiteres Zugeben von Magnesiumchloridlauge unter kräftigem Rühren in eine pastöse, für Anstrichzwecke sehr geeignete Dispersion gebracht wird.Such a combination that as a result of the lumpy taking place Excretion of magnesium silicates does not seem possible at first, but this does not appear to be possible with can very well be accomplished with some caution, combines the merits of both Paints, namely the rapid hardening of waterglass paints and the good ones Adhesion strength of Sorel cement paints. You just have to be on it respect, think highly of- that the initially formed excretion, which easily clumps together, through further addition of magnesium chloride lye while stirring vigorously into a pasty, very suitable dispersion for painting purposes is brought.

Außerdem gibt das ' agnesiumsilikat noch eine Verfestigung des sogenannten Sorelzementes und eine Erhöhung der Wetterfestigkeit durch die Verstopfung der Poren des Anstrichfilms. Beispiel Einer pastösen Mischung aus 3o Teilen 25oloiger Magnesiumchloridlauge und aus 35 Teilen Wasserglaslösung von 23 Be, wird unter Verrühren eine Paste aus 2o Teilen Pigment, 15 Teilen kaustischem Magncsit und 5o Teilen Wasser zugegeben.In addition, the 'agnesiumsilikat gives a strengthening of the so-called Sorel cement and an increase in weather resistance by clogging the pores of the paint film. Example of a pasty mixture of 30 parts of 25% magnesium chloride liquor and from 35 parts of water glass solution of 23 Be, a paste is made with stirring 20 parts of pigment, 15 parts of caustic magncsite and 50 parts of water were added.
