Description

Pyrotechnisches MittelĀ Pyrotechnic agent
Gegenstand der vorliegenden Erfindung ist ein pyrotechnisches Mittel.The subject of the present invention is a pyrotechnic agent.
Pyrotechnische Mittel im Sinne der Erfindung sind Stoffe oder Stoffgemische, die eine pyrotechnische Wirkung entfalten kƶnnen.Pyrotechnic agents in the context of the invention are substances or mixtures of substances which can develop a pyrotechnic effect.
Insbesondere Gegenstand der vorliegenden Erfindung ist ein pyrotechnisches Mittel, das als thermisches FrĆ¼hzĆ¼ndmittel eingesetzt werden kann.In particular, the subject of the present invention is a pyrotechnic agent which can be used as a thermal ignition agent.
Anwendungsbereiche solcher thermischen FrĆ¼hzĆ¼ndmittel sind beispielsweise Sicherheitssysteme, vorzugsweise thermische Sicherungen in Gasgeneratoren oder Trennelemente fĆ¼r Batterien. Solche Sicherheitssysteme werden wiederum vorzugsweise in Kraftfahrzeugen eingesetzt.Areas of application of such thermal pre-ignition agents are, for example, safety systems, preferably thermal fuses in gas generators or separating elements for batteries. Such security systems are again preferably used in motor vehicles.
Thermische FrĆ¼hzĆ¼ndmittel sind pyrotechnische Substanzen bzw. Mischungen, die unter anderem die Aufgabe haben, die in der Regel thermisch sehr stabilen Gas erzeugenden Mischungen des Gasgenerators im Falle eines Fahrzeugbrandes kontrolliert anzuzĆ¼nden.Thermal preignition agents are pyrotechnic substances or mixtures which, inter alia, have the task of controlling the generally very thermally stable gas-generating mixtures of the gas generator in the event of a vehicle fire.
Ein anderes Anwendungsbeispiel thermischer FrĆ¼hzĆ¼ndmittel ist die Verwendung als pyrotechnischer Satz in Trennelementen, vorzugsweise fĆ¼r Batterieklemmen. Diese Trennelemente sollen im Falle eines Brandes, insbesondere eines Fahrzeugbrandes, oder bei einem Kraftfahrzeugunfall, bei dem der Gasgenerator ausgelƶst wird, die Stromversorgung unterbrechen.Another application of thermal preignition agents is the use as a pyrotechnic set in separators, preferably for battery terminals. These separators should interrupt the power supply in case of fire, especially a vehicle fire, or in a motor vehicle accident in which the gas generator is triggered.
Als thermische FrĆ¼hzĆ¼ndmittel werden beispielsweise Nitrocellulose, daraus abgeleitete Treibladungspulver oder die in der Patentanmeldung DE 197 30 873 A1 beschriebenen Mischungen auf Basis von Nitrotriazolon und Guanidinnitrat eingesetzt. Diese Mischungen zeigen EntzĆ¼ndungstemperaturen von ca. 1600C und sind im Falle der Nitrocellulose nur unzureichend langzeitstabil.Nitrocellulose, propellant powder derived therefrom or the mixtures based on nitrotriazolone and guanidine nitrate described in the patent application DE 197 30 873 A1 are used as thermal premature igniters, for example. These mixtures show ignition temperatures of about 160 0 C and are insufficiently long-term stability in the case of nitrocellulose.
Aufgabe der vorliegenden Erfindung war die Bereitstellung eines pyrotechnischen Mittels mit einer EntzĆ¼ndungstemperatur um 180Ā°C und ausreichender LangzeitstabilitƤt. Eine weitere Aufgabe der vorliegenden Erfindung war die Bereitstellung eines pyrotechnischen Mittels, das als thermisches FrĆ¼hzĆ¼ndmittel fĆ¼r Gasgeneratoren in Kraftfahrzeugsicherheitssystemen eingesetzt werden kann. EineObject of the present invention was to provide a pyrotechnic agent having an ignition temperature of 180 Ā° C and sufficient long-term stability.

ErfindungsgemƤƟ wird diese Aufgabe Ć¼berraschenderweise durch die Merkmale des Hauptanspruchs gelƶst. Vorzugsweise Ausgestaltungen finden sich in den UnteransprĆ¼chen. Dabei werden erfindungsgemƤƟ Azotetrazolate als Komponente eingesetzt. Insbesondere werden dabei als Azotetrazolatkomponente Aminoguandin- 5,5'-azotetrazolat (C4H-Ī¹4NiĪ²), kurz AGATZ, und Guanidin-5,5'-azotetrazolat (C41Hi2Ni6), kurz GATZ, eingesetzt.According to the invention, this object is surprisingly achieved by the features of the main claim. Preferred embodiments can be found in the subclaims. In this case, azotetrazolates are used as component according to the invention. In particular, the azotetrazolate component employed here is amino guanandine 5,5'-azotetrazolate (C 4 H 4 NiĪ²), AGATZ for short, and guanidine 5,5'-azotetrazolate (C 41 Hi 2 Ni 6 ), GATZ for short.
Die Azotetrazolatkomponenten kƶnnen entweder alleine oder in Mischungen untereinander und/oder mit weiteren Komponenten verwendet werden. Die Strukturformeln von AGATZ und GATZ sind wie folgt:The azotetrazolate components may be used either alone or in mixtures with each other and / or with other components.

Der Verpuffungspunkt des reinen AGATZ betrƤgt 209Ā°C, der des GATZ betrƤgt 24O0C.The deflagration point of the pure AGATZ is 209 Ā° C, that of the GATZ is 24O 0 C.
Ɯberraschenderweise wurde gefunden, dass sich bei Mischungen von AGATZ und/oder GATZ und/oder ausgewƤhlten Komponenten die Verpuffungstemperaturen im Bereich von 165Ā°C bis 195Ā°C steuern lassen und die Verpuffungstemperaturen der Mischungen tiefer liegen kƶnnen als die der Einzelkomponenten.Surprisingly, it has been found that in blends of AGATZ and / or GATZ and / or selected components, the deflagration temperatures in the range of 165 Ā° C to 195 Ā° C can be controlled and the deflagration temperatures of the mixtures can be lower than that of the individual components.
FĆ¼r FrĆ¼hzĆ¼ndmittel sind Verpuffungstemperaturen unter 200Ā°C besonders interessant. Die erfindungsgemƤƟen pyrotechnischen Mittel erfĆ¼llen diese Forderung bei ausgezeichneter LangzeitstabilitƤt.For FrĆ¼hzĆ¼ndmittel deflagration temperatures below 200 Ā° C are particularly interesting.
