Description

Celluloseesterbronielack Lösungen von Celluloseestern erleiden bekanntlich in Gegenwart von Metallbronzen irreversible Zustandsänderungen; sie gelatinieren in kürzester Zeit und bilden dann eine elastische Masse, die nicht mehr streichbar ist. Es ist daher bisher noch nicht möglich gewesen, haltbare Celluloseesterbronzelacke herzustellen.Cellulose ester bronze lacquer solutions of cellulose esters are known to suffer irreversible changes of state in the presence of metal bronzes; they gelatinize in a very short time and then form an elastic mass that can no longer be painted is. It has therefore not previously been possible to produce durable cellulose ester bronze paints to manufacture.

Erfindungsgemäß gelingt es, Celluloseesterbronzelacke zu gewinnen, die nicht gelatinieren, sondern wie jeder andere Lack beliebig lange Zeiten flüssig bleiben und nach dem Aufbringen auf die zu überziehenden Flächen durch Verdunstung der Lösungsmittel zu einem Film erstarren, wenn man einem Celluloseesterlack üblicher Zusammensetzung, der mindestens ein Schwerinetall in Pulverforin enthält, noch geringe Mengen Wasserstoffsuperoxyd zusetzt.According to the invention it is possible to obtain cellulose ester bronze lacquers, which do not gelatinize but, like any other lacquer, remain liquid for any length of time remain and after application to the surfaces to be coated by evaporation the solvent solidify to a film, if you use a cellulose ester lacquer more usual Composition, which contains at least one heavy metal in powder form, still low Adds quantities of hydrogen peroxide.

Beispielsweise wird ein Nitrocelluloselack nachstehender Zusammensetzung: ii0/, Kollodiumwolle, 6 0/, Ricinusöl, 43 0/, Essigäther, 15 0/, Äthyjalkohol, 25 01, Toluol, der auf ioo Teile io Teile Bronzepulver mit einem oder mehreren Schwermetallen, etwa eine Mischung von Kupfer und Zinn, enthält, mit 5 Gewichtsprozenten einer 30prozentigen Lösung von Wasserstoffsuperoxyd versetzt. Durch diesen Zusatz wird der Lack weder in seinem Aussehen verändert, noch wird die Güte des damit erzielbaren Films beeinträchtigt, doch ist dieser Bronzelack nun praktisch unbeschränkt haltbar, ohne zu koagulieren.For example, a nitrocellulose lacquer with the following composition: ii0 /, collodion wool, 6 0 /, castor oil, 43 0 /, vinegar ether, 15 0 /, ethyl alcohol, 25 01, toluene, which contains 100 parts 100 parts bronze powder with one or more heavy metals, such as a mixture of copper and tin, mixed with 5 percent by weight of a 30 percent solution of hydrogen peroxide. This addition does not change the appearance of the lacquer, nor does it affect the quality of the film that can be achieved with it, but this bronze lacquer can now be kept practically indefinitely without coagulating.

Man hat bereits vorgeschlagen, zur Verminderung der Viskositätseigenschaften von Nitrocellulosemassen die Nitrocellulose mit einer neutralen wäßrigen Lösung von Wasserstoffsuperoxyd zu behandeln, um Nitrocelluloselösungen mit hoher Konzentration und niedriger Viskosität zu erhalten. Demgegenüber handelt es sich gemäß der Erfindung darum, bei Cellulöseesterlacken, welche durch Beimengung von einein oder mehreren Schwermetallen in Pulverform leicht zur Koagulation neigen, durch den Zusa.tz von Wasserstoffsuperoxyd vor dieser unerwünschten Koagulierung zu schützen.It has already been proposed to reduce the viscosity properties of nitrocellulose masses the nitrocellulose with a neutral aqueous solution from hydrogen peroxide to treat nitrocellulose solutions of high concentration and low viscosity. In contrast, it is according to the invention therefore, with cellulose ester lacquers, which by adding one or more Heavy metals in powder form tend to coagulate easily due to the addition of To protect hydrogen peroxide from this unwanted coagulation.
