Abstract (en)

In the production of a functional, high-energy material with laminar grains containing an energy-rich plasticizer (I) and polymeric desensitizer (II), (I) and (II) is diffused into the absorbent grains in the form of an aqueous emulsion. Independent claims are also included for: (a) functional high-energy material with laminar grains, obtained by introducing (I) and (II) into a green powder, which contains 5-20% of is a specified 2-nitroxyethyl-nitramine (IA) or dinitro-diazaalkane (IB) as (I) with respect to the green powder; (b) green grains for producing a functional high-energy material of this type.

Abstract (de)

Das Verfahren zur Herstellung von Treibladungspulver (TLP) mit schichtartigem Kornaufbau geht von einem Grünpulver aus, welches in wässriger Emulsion mit einem energetischen Weichmacher und einem polymeren Phlegmatisator imprägniert wird. TLP lassen sich so in industriellen Mengen herstellen, indem die gefährliche Direkt-Einarbeitung eines Sprengöls umgangen wird. Die so hergestellten TLP haben ähnliche Eigenschaften und einen ähnlichen Aufbau wie die vorbekannten TLP.
