und S-70) im Gewichtsverhältnis 50 : 50 enthielt, während 10 min unter lebhafter Bewegung vermischt. Dann wurde das an der Oberfläche der Masse befindliche Wasser abdekantiert und die leimartige klebrige Masse aus dem Mischer entfernt, auf einer Tasse ausgebreitet und über Nacht an der Luft getrocknet.
Nach Verdunsten von Wasser und Hexan wurde die nun nicht mehr klebrige PETN-Bindemittelmischung (Gewichtsverhältnis 70 : 30) zwischen Messingwalzen zu einem biegsamen Blatt ausgewalzt.
Das verwendete PETN hatte eine Teilchengrösse von 0, 1 bis 10 Mikron, wobei die grössten Teilchen- abmessungen im Mittel be 0, 1 - 2, 0 Mikron lagen.
Das Blatt besass eine Dichte von 1, 21 g/cm ! und eine Schlagempfindlichkeit, gemessen im StandardFalltest (5 kg-Gewicht) von 141, 9 cm (50%-Detonationspunkt). Das Blatt liess sich durch eine Sprengkap- "sei Nr. 6 zünden, wobei die Detonationsgeschwindigkeit 6500 m/sec betrug. Es war fest und biegsam, behielt jede ihm erteilte Form bei und besass gute Lagerfähigkeit.
PATENTANSPRÜCHE :
1. Selbsttragende, deformierbare Explosivstoffzusammensetzung, welche eine initial zündbare kristalline hochexplosive Verbindung im Gemisch mit einem aus 25-75% eines Elastomeren und 75-25% eines thermoplastischen Terpenkohlenwasserstoffharzes bestehenden Bindemittel enthält. dadurch gekennzeichnet, dass ihr Gehalt an der hochexplosiven Verbindung 70-77, 5% beträgt.

and S-70) in a weight ratio of 50:50, mixed for 10 minutes with vigorous agitation. The water on the surface of the mass was then decanted off and the glue-like sticky mass was removed from the mixer, spread out on a cup and air-dried overnight.
After the water and hexane had evaporated, the now no longer sticky PETN binder mixture (weight ratio 70:30) was rolled out between brass rollers to form a flexible sheet.
The PETN used had a particle size of 0.1 to 10 microns, with the largest particle dimensions being 0.1-2.0 microns on average.
The sheet had a density of 1.21 g / cm! and an impact sensitivity, measured in the standard drop test (5 kg weight) of 141.9 cm (50% detonation point). The leaf could be detonated by a No. 6 explosive cap, the detonation speed being 6500 m / sec. It was firm and flexible, retained any shape it was given, and had a good shelf life.
PATENT CLAIMS:
1. Self-supporting, deformable explosive composition which contains an initially ignitable crystalline highly explosive compound in a mixture with a binder consisting of 25-75% of an elastomer and 75-25% of a thermoplastic terpene hydrocarbon resin. characterized in that their content of the highly explosive compound is 70-77.5%.
