Description

Die Erfindung bezieht sich auf gepreßte unempfindliche Sprengstoffmischungen nach dem Oberbegriff des Anspruchs 1.The invention relates to compressed 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 Ultrasonically produced TATB (1,3,5-triamino-2,4,6-trinitrobenzene) on. This ensures that the explosives according to the GAP test as - little sensitive - was classified. 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 has for its object insensitive explosives mixtures to propose that are as simple to manufacture as possible and that are as possible low pressures of clearly <1 kbar of the theoretical maximum density> 98% obtained, that is, have a very high density of compacts.

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 in accordance with the features of the invention of claim 1. Advantageous further developments of the invention are See 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 Sprengstoffs vermieden. Problemfrei ist die Verwendung von kostengünstigem Oktogen und Hexogen der Qualität B. In addition to the insensitivity, high charge densities are advantageous through the invention achieved in terms of high detonation pressures and speeds. Because of the low pressure, the explosives are complicated Housing can be easily pressed in. At low pressures, crystal breaks of the explosives avoided. The use of inexpensive is problem-free Quality B octogen and hexogen
