Verfahren zur Herstellung eines Schiffsanstrichmittels. Patentiert im Deutschen Reiche vom 14. Oktober 1910 ab.Process for the manufacture of a marine paint. Patented in the German Empire on October 14, 1910.
Es sind schon Schiffsbodenanstriche hergestellt worden, die Kupfer in fein zerteiltem Zustande oder mehr oder weniger lösliche Verbindungen desselben in einem wasserfesten Firnis eingebettet enthalten.Strips have already been painted with finely divided copper Forms or more or less soluble compounds of the same in a water-resistant one Embedded varnish included.
Solche Anstriche haben sich aber auf die Dauer nicht bewährt, da es einerseits bei alleiniger Verwendung von Kupfer an einem geeigneten Mittel fehlt, welches die ReaktionSuch coatings have not proven themselves in the long run, because on the one hand there is the mere use of copper lacks a suitable means of preventing the reaction
ίο zur raschen Lösung des Kupfers fördert, um dessen vergiftende Wirkung sofort zu äußern, und da andererseits ein Anstrich, der nur eine Kupferverbindung, wie z. B. getrocknetes Kupfersulfat oder Kupferchlorid in einen Firnis eingebettet enthält, sich nur während kurzer Zeit gut erhält, dann aber rasch zersetzt wird und von der zu schützenden Fläche abfällt. Es wurde nun versucht, Kupferchlorür, welches, obschon dessen Giftigkeitίο promotes rapid dissolution of the copper in order to to express its poisoning effect immediately, and on the other hand, a paint that only a copper compound such as B. dried copper sulfate or copper chloride in a varnish contains embedded, is only well preserved for a short time, but then quickly decomposes and falls away from the surface to be protected. An attempt has now been made to obtain copper chloride, which, although its toxicity
so bekannt sein mußte, noch nicht zu Anstrichen verwendet worden war, in einen Firnis einzubetten, und es zeigte sich, daß ein solcher Anstrich, nachdem er einmal auf die zu schützende Fläche aufgetragen ist, viel dauerhafter und wirkungsvoller war als ein Kupfersulfat oder -chlorid enthaltender Anstrich. Doch bald entdeckte man auch hier einen nicht geringen Nachteil, der darin bestand, daß die Anstrichmasse nicht zum Voraus hergestellt werden konnte, da sie sich nicht aufbewahren ließ. Die Erfinderin hat nun gesucht, ein Anstrichmittel herzustellen, welches die oben erwähnten Nachteile nicht besitzt, und diese Herstellung ist ihr auch gelungen.had to be so well known not yet to be painted had been used to embed in a varnish, and it was found that such a coating, after it is applied once to the surface to be protected, much more permanent and was more effective than paint containing copper sulfate or chloride. But soon Here, too, a not insignificant disadvantage was discovered, which consisted in the fact that the paint could not be prepared in advance because it could not be stored. The inventor has now looked for a paint manufacture which does not have the above-mentioned disadvantages, and this manufacture she also succeeded.
Das neue Anstrichmittel bildet den Gegenstand vorliegender Erfindung. Dieses Anstrichmittel wird dadurch hergestellt, daß man entwässertes Kupfersulfat bzw. Kupferchlorid mit einem geringen Überschuß von Kupferpulver in einen wasserfesten Firnis einbettet, so daß sich, sobald die in dem Anstriche verhandenen Kupfersulfat- bzw. Kupferchlorid- und Kupferteilchen infolge Zerstörung des Firnisses durch die Mollusken bzw. Algen entblößt werden und mit dem Meereswasser in Berührung kommen, Kupferchlorür (Cu2 Cl2) bildet, welches durch seine vergiftende Wirkung die Wassertiere bzw. Pflanzen abtötet.The new paint forms the subject of the present invention. This paint is produced by embedding dehydrated copper sulfate or copper chloride with a small excess of copper powder in a waterproof varnish, so that as soon as the copper sulfate or copper chloride and copper particles contained in the paint are destroyed, the varnish is destroyed by the mollusks or algae are exposed and come into contact with sea water, forming copper chloride (Cu 2 Cl 2 ) , which kills aquatic animals and plants through its poisoning effect.
Der leichte Überschuß an Kupferpulver, etwa Y2 Molekül, bezweckt, ein Zerfallen des Anstriches zu verhüten, das infolge der Wasseraufnahme durch das entwässerte Kupfersulfat und der dadurch bewirkten Vergrößerung des Molekularvolumens desselben stattfinden würde, wenn das Anstrichmittel die zur Bildung von Kupferchlorür in Gegenwart des Chlornatriums des Meerwassers gerade nötigen, theoretischen Mengen entwässertes Kupfersulfat und Kupfer enthalten würde.The slight excess of copper powder, about Y 2 molecule, aims to prevent the paint from disintegrating, which would take place as a result of the water absorption by the dehydrated copper sulfate and the resulting increase in the molecular volume of the same, if the paint was capable of forming copper chlorine in the presence of the Sodium chloride in seawater would contain the theoretical amounts of dehydrated copper sulfate and copper.
Zur Herstellung des Schiffsanstrichmittels nach vorliegender Erfindung verfährt man z. B. auf folgende Weise:The same procedure is used to produce the marine paint according to the present invention z. B. in the following way:
75 kg wasserfester Firnis, 30 kg roter Ocker, 20 kg entwässertes Kupfersulfat und 8 kg75 kg of waterproof varnish, 30 kg of red ocher, 20 kg of dehydrated copper sulfate and 8 kg
