Description

Verfahren zur Herstellung von weitestgehend stabilen Nitrocelluloselacken Ein großes Hindernis für die weitere Ausdehnung der Lackierung mit Nitrocelluloselacken ist die schlechte Eignung der Nitrocelluloselackierung für Außenanstriche. Nur schwierig und unzulänglich kann man verhindern, daß in Außenanstfichendie einzelnen Komponenten der Nitrocellulose mit aller Gewalt wieder auseinanderstreben und dadurch die Zersetzung des Anstrichfilms einleiten.Process for the production of largely stable nitrocellulose lacquers A major obstacle to the further expansion of painting with nitrocellulose paints is the poor suitability of nitrocellulose paints for exterior paints. Just difficult and inadequately it is possible to prevent the individual components from being pierced in the exterior the nitrocellulose strive again with all its might and thereby the decomposition of the paint film.

Durch Zusatz von Farbpigmenten erreicht man eine etwas größere Stabilität; aber die Resultate lassen in vieler Hinsicht noch zu wünschen übrig: In der Schießwollpulvertechnik bezeichnet man als Stabilisatoren solche Körper, die die Stabilität der Schießwolle erhöhen bzw. die Stickoxydabspaltung hintanhalten oder aufnehmen, und als Dephlegmatoren solche Zusätze, die auf Verbrennung und Umsatz verzögernd wirken. Ein Stabilisator ist z. B. das Diphenylamin, ferner Harnstoffderivate; ein Dephlegmator z. B. der Campher. Wenn man dafür sorgt, daß diese Stabilisatoren und Dephlegmatoren in allerfeinster Verteilung, also in höchster Kolloiddispersion, die einzelnen Cellulosederivatmoleküle umgeben und so auch die geringste Abspaltung von nitrosen Gasen im Keime ersticken, so erreicht man auch hei Nitrocelluloselacken sehr gute Resultate. Es wurde nun gefunden, daß man noch weitergehende Stabilität durch Zugabe von artfremden Schutzkolloiden erreichen kann, während die arteigenen Schutzkolloide, wie z. B. Acetylcellulose und Celluloseäther, deren Anwendung bereits bekannt ist, lange nicht denselben Effekt erreichen. Wichtig ist, daß dabei gleichzeitig ein Ausgleich der PH-Spannung bewirkt wird.A somewhat greater stability is achieved by adding color pigments; but the results leave a lot to be desired in many respects: in gunwool powder technology One designates as stabilizers those bodies, which the stability of the gun wool increase or prevent or absorb the elimination of nitrogen oxide, and as dephlegmators those additives that have a retarding effect on combustion and turnover. A stabilizer is z. B. Diphenylamine, also urea derivatives; a dephlegmator e.g. B. the Camphor. If you make sure that these stabilizers and dephlegmators are in the finest quality Distribution, i.e. in the highest colloid dispersion, of the individual cellulose derivative molecules and thus nip even the slightest splitting of nitrous gases in the bud, in this way, very good results can also be achieved with nitrocellulose lacquers. It was now found that even greater stability can be obtained by adding foreign protective colloids can achieve, while the native protective colloids such. B. acetyl cellulose and cellulose ethers, the use of which is already known, far from having the same effect reach. It is important that the PH voltage is balanced at the same time will.

Zu diesem Zwecke eignen sich - sehr gut methyl- und äthylalkoholische Auszüge aus Casein, die in der Hauptsache Lecithin enthalten, sowie Cholesterin und Oxycholesterin, Glukose und andere artfremde Kolloide, die in den Lösungsmitteln etwas löslich sein müssen und die ihrerseits einen Ausgleich der PH-Spannung bewirken können.Suitable for this purpose are - very good methyl and ethyl alcoholic Casein extracts, which mainly contain lecithin, and cholesterol and oxycholesterol, glucose and other alien colloids found in the solvents must be somewhat soluble and which in turn balance the PH voltage can.
