Frostsicheres FeuerlöschmittelFrost-proof fire extinguishing agent
Die Erfindung betrifft ein frostsicheres Feuerlöschmittel, welches aus einer wäßrigen Emulsion von halogenierten, vorzugsweise bromierten Kohlenwasserstoffen besteht und dem zur Erzielung der notwendigen Frostsicherheit Elektrolyte zum AVasseranteil sowie zur Vermeidung der durch die Elektrolyte normalerweise erfolgenden Aussalzung der Emulgatoren ein gewisser Anteil von Cellulosederivaten oder Celluloseabkömmlingen hinzugefügt sind.The invention relates to a frost-proof fire extinguishing agent, which consists of an aqueous emulsion of halogenated, preferably brominated, hydrocarbons exists and the electrolyte to achieve the necessary frost protection for the water content as well as to avoid the caused by the Electrolytes normally take place salting out the emulsifiers a certain proportion of cellulose derivatives or cellulose derivatives are added.
Bei derartigen Feuerlöschmitteln besteht die Schwierigkeit, daß derartige Lösungen die Emulgierbarkeit stark herabsetzen. Eine Anwendung organischer Frostschutzmittel ist aber wiederum wegen der damit verbundenen Verschlechterung der Löschwirkung nicht zu empfehlen. Nach der Erfindung wird aber eine stabile Emulsion dennoch erzeugt durch Anwendung eines polymeren, wasserlöslichen, hochmolekularen Cellulosedenivates, nämlich des Natriumoelluloseglykolats, welches dem Netzmittel zugefügt wird. Eine erfindungsgemäße Emulsion erhält man beispielsweise aus 300 Teilen Monochlorbrommethan, 600 Teilen wäßriger Pottaschelösung von 35° Be, 60 TeilenWith such fire extinguishing agents there is the problem that such solutions the emulsifiability greatly reduce. An application of organic antifreeze is again not recommended because of the associated deterioration in extinguishing effectiveness. After Invention, however, a stable emulsion is still produced by using a polymeric, water-soluble, high molecular weight cellulose derivative, namely the sodium oilulose glycolate, which is added to the wetting agent. An inventive Emulsion is obtained, for example, from 300 parts of monochlorobromomethane, 600 parts aqueous potash solution of 35 ° Be, 60 parts

Celluloseester, Acetyleellulose, Nitrocellulose sind wegen ihrer Unlöslichkeit bzw. nur geringen Löslichkeit in Wasser ungeeignet. Methylcellulose besitzt in kaltem Wasser ebenfalls keine genügende Löslichkeit. Carboxymethylcellulose dagegen in Form des Natriumsalzes der Celluloseglykolsäure, also Natriumcelluloseglykolat, löst sich in kaltem wie warmem Wasser unter Quellung zu" Grellösungen bzw. bei weiterem Wasserzusatz zu klaren, nicht schäumenden, fast farblosen Sollösungen. Diese kolloidalen Lösungen sind kochbeständig und werden auch durch Gefrieren nicht zerstört. Die Emulgierfähigkeit von Natriumcelluloseglykolatsollösungen ist sehr gut." Außerdem sind die Sollösungen gegen Elektrolyte ziemlich beständig. Natriumcelluloseglykolat wirkt auch als Zusatz besonders zu Schmierseifen hemmend auf die Bildung von Kalkseife, vermag also offenbar das Calcium des Leitungswassers zu binden, ohne dabei , auszuflocken. Dies ist deshalb wichtig, wenn zur Herstellung der Halogenwasserstoff-Wasser-Emulsionen Leitungswasser benutzt wird. Die Frostbeständigkeit ' einerseits und die relativ gute Beständigkeit der Natriumcelluloseglykolatsollösungen gegenüber Elektrolyte machen es erst möglich, durch Zusatz von z. ;B. Pottasche zu Halogenwasserstoff-Wasser-Emulsionen diesen die gewünschte Frostbeständigkeit zu geben.Cellulose esters, acetyl cellulose, and nitrocellulose are unsuitable because of their insolubility or only poor solubility in water. Methyl cellulose also has insufficient solubility in cold water. Carboxymethyl cellulose, on the other hand, in the form of the sodium salt of cellulose glycolic acid, i.e. sodium cellulose glycolate, dissolves in cold and warm water and swells to form "bright solutions" or, with further addition of water, to clear, non-foaming, almost colorless sol solutions. These colloidal solutions are resistant to boiling and do not freeze The emulsifiability of sodium cellulose glycolate solutions is very good. " In addition, the sol solutions are quite resistant to electrolytes. Sodium cellulose glycolate, especially when used as an additive to soft soaps, has an inhibiting effect on the formation of lime soap, so it is apparently able to bind the calcium in tap water without flocculating. This is therefore important when tap water is used to prepare the hydrogen halide-water emulsions. The frost resistance 'on the one hand and the relatively good resistance of the sodium cellulose glycolate solutions to electrolytes make it possible only by adding z. ; B. Potash to hydrogen halide-water emulsions to give these the desired frost resistance.
