Diehl Munitionssysteme GmbH & Co. KG, D-90552 RöthenbachDiehl Munitionssysteme GmbH & Co. KG, D-90552 Röthenbach Gepresste unempfindliche SprengstoffmischungPressed insensitive explosive mixture

Die Erfindung bezieht sich auf gepresste unempfindliche Sprengstoffmischungen nach dem Oberbegriff des Anspruchs 1.The invention relates to pressed insensitive explosive mixtures according to the preamble of claim 1.

Aus der DE 199 55 657 A1 sind derartige Sprengstoffmischungen bekannt. Sprengstoffkristalle, wie Hexogen, Oktogen, CL20, weisen eine Bindermatrix aus sonochemisch hergestellten Feinst-TATB (1,3,5-Triamino-2,4,6-Trinitrobenzol) auf. Dadurch wird erreicht, dass der Sprengstoff gemäß dem GAP-Test als - wenig empfindlich - klassifiziert wurde. Die benötigte Presskraft beträgt > 2 kbar.Such explosive mixtures are known from DE 199 55 657 A1. Explosive crystals such as hexogen, octogen, CL20 have a binder matrix made of sonochemically produced ultra-fine TATB (1,3,5-triamino-2,4,6-trinitrobenzene). This means that the explosive is classified as - not very sensitive - according to the GAP test. The required pressing force is > 2 kbar.

Der Erfindung liegt die Aufgabe zugrunde, unempfindliche Sprengstoffmischungen vorzuschlagen, die möglichst einfach herstellbar sind und die bei möglichst geringen Pressdrücken von deutlich < 1 kbar der theoretischen Maximaldichte > 98 % erhalten, also eine sehr hohe Presskörperdichte aufweisen.The invention is based on the object of proposing insensitive explosive mixtures which are as simple to produce as possible and which maintain > 98% of the theoretical maximum density at the lowest possible pressing pressures of significantly < 1 kbar, i.e. which have a very high compact density.

Die Erfindung löst diese Aufgabe entsprechend den erfindungsgemäßen Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.The invention solves this problem according to the inventive features of claim 1. Advantageous further developments of the invention can be found in the subclaims.

Vorteilhaft werden durch die Erfindung neben der Unempfindlichkeit hohe Ladungsdichten erzielt im Hinblick auf hohe Detonationsdrücke und geschwindigkeiten. Aufgrund des niedrigen Pressdruckes sind die Sprengstoffe in komplizierte Gehäuse ohne weiteres einpressbar. Bei den niedrigen Pressdrücken werden Kristallbrüche des SprengstoffsThe invention is advantageous in that it achieves high charge densities in addition to its insensitivity with regard to high detonation pressures and velocities. Due to the low pressing pressure, the explosives can be easily pressed into complicated casings. At the low pressing pressures, crystal fractures of the explosives

vermieden. Problemfrei ist die Verwendung von kostengünstigem Oktogen und Hexogen der Qualität B.avoided. The use of inexpensive octogen and hexogen of quality B is problem-free.

Die Ladungen sind recyclebar im Sinne einer neuen Granulation. 5The loads are recyclable in the sense of new granulation. 5

Durch Wahl der bimodalen Korngrößenverteilung und Zusammensetzung des Lösungsmittels für die Anfertigung des Binderlackes HYTEMP® und DOA, sowie unterschiedlicher Anteil an Lösungsmittelmischung im Lack führen zu Sprengstoffmischungen, die unterschiedlich unempfindlich und im GAP-Test bis zu der Einstufung wenig empfindlich nach Stanag 4170 und bei spezifischen Pressdrücken - kaliberabhängig - bereits von 0,6 0,9 kbar mehr als 98 % der theoretischen Dichte erreichen.By choosing the bimodal grain size distribution and composition of the solvent for the production of the binder varnish HYTEMP® and DOA, as well as different proportions of solvent mixture in the varnish, explosive mixtures that have varying degrees of insensitivity and in the GAP test up to the classification of low sensitivity according to Stanag 4170 and at specific pressing pressures - depending on the caliber - already reach more than 98% of the theoretical density.
