Definitions
- the invention relates to a method for producing a pressed, insensitive explosive mixture according to the European patent application EP 1 101 751 A.
- the invention has for its object insensitive, high-performance To propose compacts also for beam and projectile-forming shaped charges.
- the process according to the invention provides crack-free compacts.
- the sonochemical synthesis of TATB is a so-called Two phase reaction, taking a solution of TCTNB (trichlorotriaminobenzene) in Toluene with ammonia solution, which is immiscible with this solution, for the reaction brought.
- TCTNB triaminobenzene
- the activation energy required for this is provided by a strong one Ultrasound source applied, which also for an extraordinary strong enlargement of the phase interfaces where the chemical conversion takes place, ensures.
- the ultrafine TATB that is created during the reaction can be easily filtered, washed and dried, and can then be used to prepare the above Explosives are used.
- a suspension of the respective is generated by means of ultrasound Secondary explosives (in the delivered, moistened state), i.e. RDX, HMX or CL-20, nitropenta ... in excess, watery, approx. 30% Ammonia solution and drips a calculated according to the reaction conversion Amount of TCTNB dissolved in toluene.
- the resulting ultra-fine TATB is now stored directly in situ on the suspended Secondary explosive particles.
- This adsorption process is also enormously promoted by training strong hydrogen bonds between the nitro groups of the secondary Explosives and the amino groups of the TATB.
- the product obtained can be fed directly to further processing.
- blasting and projectile-forming explosive compact has the insensitive Explosives mixture directly attached to the secondary explosives TATB.
- Small amounts of binders e.g. DOA, calcium stearate, Aerosil be included.
