Abstract (en)

Production of a mono-, di- or tribasic gun propellant powder comprises subjecting particles of a conventional propellant powder, comprising nitrocellulose, nitrate esters, alkyl nitratoethyl nitramines, nitroguanidine, hexogen, octogen, 3-nitro-1,2,4-triazol-5-one and/or hexanitrohexaazaisowurtzitan, to surface treatment with inert or energetic polymers and/or energetic monomeric plasticizers.

Abstract (de)

Die Erfindung betrifft ein Verfahren zur Herstellung von einzwei- oder dreibasigen Treibladungspulvern für Rohrwaffenmunition, wobei an sich bekannte ein-, zwei- oder dreibasige Treibladungspulver, die folgende Bestandteile als Energieträger enthalten: Nitrocellulose, Salpetersäureester, Alkylnitratoethylnitramine, Nitroguanidin, Hexogen, Oktogen 3-Nitro-1,2,4-Triazol-5-on (NTO), Hexanitrohexaazaisowurtzitan (CL20) oder Mischungen derartiger Pulver, mit Hilfe phlegmatisierender Stoffe oberflächenbehandelt werden. Um eine Abflachung der Maximaldruckkurve des Treibladungspulvers in dem Temperaturbereich, für den die entsprechende Waffe bestimmt ist, zu erreichen, schlägt die Anmeldung vor, die Oberflächenbehandlung des Treibladungspulvers mit Hilfe inerter oder energetischer Polymere bzw. mit Hilfe energetischer monomerer Weichmacher oder mit Hilfe von Mischungen aus beiden Komponenten vorzunehmen. <IMAGE>
