Abstract
Description
Gelartiges Feuerlöschmittel Die Verwendung von Halogenkohlenwasserstoffen, im folgenden HKW genannt, zur Brandbekämpfung ist im Prinzip bereits bekannt. Gel-like fire extinguishing agent The use of halogenated hydrocarbons, hereinafter referred to as HKW, for fire fighting is already known in principle.
Es bereitete bisher jedoch Schwierigkeiten, derartige Substanzen an den Brandherd heranzubringen, sofern as sich nicht um fest installierte Raumschutzanlagen handelt.However, it has hitherto been difficult to prepare such substances Bringing up the source of the fire, provided that it is not permanently installed room protection systems acts.
EinP Aufgabe der vorliegenden Erfindung ist es daher, Halogenkohlenwasserstoffe in eine Form zu bringen, die aus Löschgeräten in Form eines zusammenhängenden Strahles verspritzt und so in den Brandherd verbracht werden kann. Erst dort soll der löschende HKW durch die Hitze des Brandes verdampft und als Löschmittel wirksam worden.It is therefore an object of the present invention to provide halogenated hydrocarbons to bring into a form, the extinguishers in the form of a coherent beam splashed and can thus be brought into the seat of the fire. Only there is the one to delete HKW evaporated by the heat of the fire and became effective as an extinguishing agent.
Diese Aufgabe wird erfindungsgemäß durch ein gelartiges Feuerlöschmittel gelöst, das alls Halogenkohlenwasserstoffen und Nontmorilloniten als Geliermittel besteht und gegebenenfalls zusätzlich Wasser und Netzmittel enthält.According to the invention, this object is achieved by a gel-like fire extinguishing agent dissolved, all halogenated hydrocarbons and nontmorillonites as gelling agents exists and, if applicable additionally contains water and wetting agents.
Als Geliermitttel eignen sich besonders Rentonite. Vorzugsweise werden erfindungsgemäß als Geliermittel 1 - 10 % Dimethyldioctadecylammoniumbentonit verwendet. Als HaloE-enkohlenw;r sserstof fe eignen sich vorzugsweise solche, die zwischen - 10°C und + 45 0G sieden.Rentonites are particularly suitable as gelling agents. Preferably be According to the invention, 1-10% dimethyldioctadecylammonium bentonite is used as a gelling agent. Suitable haloE carbons are preferably those which are between Boil - 10 ° C and + 45 0G.
Die Umwandlung von Montmorillonit in eine für den Gelierprozess geeignete Form ist im Prinzip bereits bekannt (US-Patent Nr.The transformation of montmorillonite into one suitable for the gelling process The shape is already known in principle (US patent no.

Die erfindungsgemäßen Feuerlöschmittel werden vorteilhaft dadurch hergestellt, daß die Geliermittel mit polaren Lösungsmitteln versetzt und mit den Halogenkohlenstoffen ultrascbnell verrührt werden. Im Falle der Verwendung von zusätzlichem Wasser wird zunächst das Wasser mit dem Geliermittel ultraschnell so lange verrührt, bis eine homogene, gelartige Masse entsteht und in dieser werden nach Zugabe eines Netzmittels die Halogenkohlenwasserstoffe unter Rühren gleichmäßig suspendiert.The fire extinguishing agents according to the invention are thereby advantageous made that the gelling agent mixed with polar solvents and with the Halocarbons can be stirred extremely quickly. In the case of using additional Water, the water is mixed with the gelling agent ultrafast so long, until a homogeneous, gel-like mass is formed and after adding a Wetting agent, the halogenated hydrocarbons are evenly suspended with stirring.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den folgenden Ausführungsbeispielen: Beispiel 1: Ein Gemisch aus 3 - 10 % Dimethyldioctadecyl smm oniumbentonit 0,9 - 3 % Methanol und 96,1 -87 % eines HKW's wird mit einem ultraschnell laufenden Rührer so lange verrührt, bis ein gleichmäßiz geliertes Produkt entstanden ist. Die 7ähigkeit dieses Gemisches ist abhängig von der Menge des zugesetzten Bentonits und kann wischen sirupös und geleeartig eingestellt wesen. Es ist in dieser Form direkt als Löschmittel einsetzbar.Further features and advantages of the invention will emerge from the following Working examples: Example 1: A mixture of 3-10% dimethyldioctadecyl smm onium bentonite 0.9-3% methanol and 96.1-87% of a HKW is stirred with an ultra-fast stirrer until it becomes even gelled product has arisen. The ability of this mixture depends on the amount of added bentonite and can be adjusted to a syrupy or jelly-like wipe being. In this form it can be used directly as an extinguishing agent.
Beispiel 2: Es werden folgende Bestandteile verwendet: 1 - 7 % eines hydrophilen Bentonits z.B. dem in Fall angewendeten 10 - 70 % Wasser 0,5 - 2 % eines handelsüblichen Netzmittels 88,5- 21 % HKW Zunächst wird das Bentonit mit dem Wasser im Rührwerk so lange behandelt, bis eine homogene, geleeartige Substan@ entstanden ist. Nach Zugabe des Netzmittels wird der HKW unter Rühren eingebracht und gleichmäßig suspendiert.Example 2: The following ingredients are used: 1 - 7% of one hydrophilic bentonite e.g. the 10 - 70% water used in this case 0.5 - 2% of a commercial wetting agent 88.5-21% HKW First the bentonite is mixed with the water Treated in the agitator until a homogeneous, jelly-like substance was formed is. After adding the wetting agent, the HKW is introduced with stirring and evenly suspended.
Beispiel 3: Es werden 2 Gele hergestellt, unter Verwendung von a) Bentonit + Wasser, wie in Beispiel 2 beschrieben und b) bentonit, Methanol oder einem anderen nolaren Lösungsmittel und HKW wie in Beispiel 1 beschrieben.Example 3: 2 gels are prepared using a) Bentonite + water, as described in Example 2 and b) bentonite, methanol or another molar solvent and HKW as described in Example 1.
Diese beiden Gele können in beliebigen Mengenverhältnissen miteinander vermischt werden und ergeben salbenartige Gemische, deren Konsistenz durch die Menge des zugesetzten Gels b) beeinflußt werden kann.These two gels can be used in any proportions mixed and result in ointment-like mixtures, the consistency of which depends on the amount of added Gels b) can be influenced.
