Process for the production of a pressed insensitive explosive mixture

Abstract

For the crack-free production of pressed explosive bodies, in particular jet- and projectile-forming pressed explosive bodies the insensitive explosive mixture has TATB deposited directly on the secondary explosive. It may contain small proportions of binders, for example DOA, calcium stearate or Aerosil.

1 . A process for the production of a pressed insensitive explosive mixture in which the binding agent comprises sonochemically produced 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), characterised in that the TATB which is produced by ultrasound from TCTNB is deposited in very fine particle form on the secondary explosive crystals present in the bath.  
     
     
         2 . A process according to  claim 1  characterised in that the TATB disposed in the mixer is dropped into a TCTNB solution.  
     
     
         3 . A process according to  claim 1  characterised in that the explosive mixture containing TATB is sonochemically produced in the presence of the secondary explosive directly from the preliminary stage TCTNB.  
     
     
         4 . A process according to  claim 1  characterised in that there are added to the explosive mixture small proportions of 0.1 to 3% of binder additives such as DOA (plasticiser), calcium stearate, or Aerosil, for controlling the properties of the pressed bodies.
