Druckgaserzeugende ladungenCompressed gas generating charges

Die Schubkraft \on Gasen, die bei einer chemischen Reaktion entstehen, wird in der Technik ausgenutzt, um, z.B. bei Feuerlöschern, Flüssigkeiten oder Peststoffe aus einem Behälter auszutreiben. Andere Geräte verwenden diese Kraft, um Schieber oder Riegel zu betätigen oder andere Arbeit zu leisten, vergleiche z.B. deutsche Patentschrift 854 770 Einleitung.The thrust \ of gases produced in a chemical reaction are used in technology to, e.g. with fire extinguishers, liquids or pesticides from a container to drive out. Other devices use this force to operate slides or bolts or to do other work, compare e.g. German patent specification 854 770 introduction.

Al3 gaserzeugende Ladungen sind für diesen Zweck' Stoffe oder Mischungen bekannt, die ganz oder zum größten Teil auf der Grundlage brennbarer, gas- und wärmeliefernder Stoffe aufgebaut sind. Solche Stoffe können ohne Sauerstoffzufuhr verbrennen, wie z.B. Nitrozellulosepulver oder Nitropolystyrol, oder aber sie bestehen aus Gemischen von sauerstoffliefernden Stoffen einerseits, wie z.B. Kaliumchlorat, und gasliefernden Stoffen andererseits, wie Ammoniumnitrat oder Guanidinnitrat; vergleiche z.B. deutsche Patentschriften 854 770, 851'919 und 909 424.Al3 gas-generating charges are for this purpose 'substances or Mixtures known that are built entirely or for the most part on the basis of flammable, gas and heat-releasing substances are. Such substances can burn without the supply of oxygen, such as nitrocellulose powder or nitropolystyrene, or they consist of mixtures of oxygen-supplying substances on the one hand, such as potassium chlorate, and gas-supplying substances On the other hand, substances such as ammonium nitrate or guanidine nitrate; compare e.g. German patents 854 770, 851'919 and 909 424.

Solche Mischungen enthalten z.B. Amraoniumoxalat oder in endothermer Reaktion zerfallende Kohlenwasserstoffe., wie z.B. Cyclopentadien (deutsche Patentschriften 882 825 bzw. 1 150 914).undesirable, and so mixtures have become known, v / elche the heat generated by the oxidation is consumed by a simultaneous endothermic process. Such Mixtures contain e.g. ammonium oxalate or in endothermic Hydrocarbons that decompose in the reaction, such as cyclopentadiene (German patents 882 825 and 1 150 914).

Erwünscht ist in allen Fällen die Entwicklung einer möglichst großen Menge Gas ohne Tendenz zur explosiven Selbstzersetzung der Ladung während der Entwicklungszeit und eine möglichst große Handhabungssicherheit, d.h. weitgehende Unempfindlich- ■ keit gegen Zündung durch Reibung und Schlag. So neigen z.B. Mischungen mit größeren Anteilen an Guanidinnitrat zu explosionsartiger Umsetzung, die zur Zerstörung des Behälters führen kann.In all cases it is desirable to develop as large an amount of gas as possible without a tendency towards explosive self-decomposition the charge during the development time and the greatest possible handling safety, i.e. largely insensitive- ■ ability to prevent ignition by friction and impact. For example, mixtures with larger proportions of guanidine nitrate tend to be more explosive Implementation that can lead to the destruction of the container.

Gegenstand der vorliegenden Erfindung sind nun druckgaserzeugende Ladungen, insbesondere zur Verwendung in druckgasbetriebenen Geräten, welche dadurch gekennzeichnet sind, daß sie 40 bis 100 Gewichtsprozent Aminoguanidinsalze des Azotetrazols und/oder des Ditetrazols enthalten, wobei gegebenenfalls als Zuschlagstoffe keine Detonation verursachende, sauerstoffliefernde und/oder andere gaserzeugende Stoffe eingesetzt werden.The present invention now relates to charges that generate compressed gas, in particular for use in compressed gas-operated charges Devices which are characterized in that they contain 40 to 100 percent by weight of aminoguanidine salts of azotetrazole and / or of the ditetrazole, with any additives that do not cause detonation, oxygen-supplying and / or other gas-generating substances are used.

Die Wasserstoffatome reagieren sauer und bilden daher mit Aminoguanidin die entsprechenden Salze. Deren Herstellung erfolgt 2.B. durch Zusammengeben wäßriger Lösungen von Salzen des Aminoguanidine, z.B. Aminoguanidinsulfat, mit wäßrigen Lösungen von Alkalisalzen der genannten Tetrazole, wobei die unlöslichen Verbindungen ausfallen, die gemäß der vorliegenden Erfindung zum Einsatz kommen. The hydrogen atoms react acidic and therefore form the corresponding salts with aminoguanidine. Their production takes place 2.B. by combining aqueous solutions of salts of aminoguanidine, for example aminoguanidine sulfate, with aqueous solutions of alkali metal salts of the tetrazoles mentioned, the insoluble compounds which are used according to the present invention being precipitated.
