Description

Gegenstand der vorliegenden Erfindung ist eine Feuertöschzusammensetzung, die beim Abbrennen ein Aerosol erzeugt.The present invention is a fire extinguishing composition, the when burning produces an aerosol.

In der europäischen Patentanmeldung EPA 0 627 244 wird eine Feuerlöschzusammensetzung beschrieben, die aus einer thermisch zerstreubaren Komponente, einem Oxidationsmittel, einem sauerstoffhaltigen Bindemittel und diversen Zugaben besteht. Beim Abbrand dieser Zusammensetzung wird ein Aerosol gebildet, das zum Brandlöschen eingesetzt werden kann.European Patent Application EPO 0 627 244 discloses a fire extinguishing composition described, consisting of a thermally dispersible component, an oxidizing agent, an oxygen-containing binder and various additives consists. During the burning of this composition, an aerosol is formed, which is used for Fire extinguishing can be used.

Diese bekannten Löschsätze weisen gravierende Nachteile auf. Werden sauerstoffhaltige, inaktive Bindemittel eingesetzt, beispielsweise solche, die in der obengenannten EPA auf Seite 19 unter Punkt 3 und 4 beschrieben werden, ergibt sich eine unzureichende Anzündfreundlichkeit und vor allem eine instabile Verbrennung. Die Gasproduktion des Aerosols ist eingeschränkt. Werden aber aktive, sauerstoffhaltige Bindemittel benutzt, beispielsweise Zellulosenitrat oder als Plastifikatör Glyzerintrinitrat, so wird der Abbrand zwar positiv unterstützt, doch besitzt der gesamte Löschsatz keine ausreichende thermische Stabilität. Die in der obengenannten EPA aufgeführten aktiven Bindemittel oder Plastifikatoren gehören der Gruppe der organischen Nitrate an. Es ist bekannt, daß diese Nitrate keine ausreichende thermische Stabilität zeigen. Enthält beispielsweise Munition solche Nitrate, dann ist die Lagerfähigkeit solcher Zusammensetzungen auf +63°C beschränkt. Salpetrige Ester höherwertiger Alkohole, beispielsweise NGL und DEGN neigen darüber hinaus zum Ausschwitzen.These known extinguishing rates have serious disadvantages. Become oxygenated, used inactive binders, for example those used in the The above-mentioned EPO on page 19 under point 3 and 4 are described results insufficient ignitability and above all unstable combustion. The gas production of the aerosol is limited. But become active, oxygenated binders are used, for example, cellulose nitrate or as Plastifikatör glycerol trinitrate, so the burn is indeed supported positive, but owns the total extinguishing rate does not provide sufficient thermal stability. The in the The above-mentioned EPA listed active binders or plasticizers include the Group of organic nitrates on. It is known that these nitrates no show sufficient thermal stability. Contains, for example, ammunition such Nitrates, then the shelf life of such compositions is + 63 ° C limited. Nitrous esters of higher alcohols, for example NGL and DEGN In addition, they tend to exude.

Feuerlöschzusammensetzungen, die diese Komponenten enthalten, sind daher in höheren Temperaturbereichen (>85°C) nicht einsetzbar.Fire-extinguishing compositions containing these components are therefore in higher temperature ranges (> 85 ° C) can not be used.

Eine Aufgabe der vorliegenden Erfindung bestand daher darin, Feuerlöschzusammensetzungen bereitzustellen, die die Nachteile des Standes der Technik nicht aufweisen. It is an object of the present invention to provide fire extinguishing compositions to provide the disadvantages of the prior art not exhibit.

Ein solcher Feuertösch-Treibsatz kann nicht alle an effektive, universell einsetzbare Feueriöschzusammensetzungen gestellten Anforderungen erfüllen.In DE 1 175 082 a fire extinguishing propellant is described, in addition to nitroguanidine as the only for the purposes of the present invention to be understood active binder Silicone resin is the only one to be understood in the context of the present invention contains inactive binder.
