Definitions

  • the present invention relates to plastic-bonded explosive formulations based on chlorinated rubber matrices and their use in ammunition, in particular hand grenades.
  • the ratio of net explosive mass (NEM) to total mass is approximately between 0.15 (small OHG) and a maximum of 0.7 (large OHG), corresponding to an explosive content of about 15% by weight. to 70% by weight.
  • the ratio of net explosive mass to the total mass is unfavorable, since here for reasons of manageability, the weight of Kipphebelzünderbauou devise with Anzündverzögerungs- and detonator can not be reduced.
  • the ratio of NEM to total mass could be increased by reducing the wall thickness of the hand grenade body.
  • the NEM can be additionally increased by omitting the most common splinter-free "blind insert"
  • the aforementioned possibilities for increasing the net explosive mass are structurally narrow limits.
  • DE 36 25 412 C2 relates to a method for producing a plastic-bound explosive and its use.
  • the explosive, the plastic, a solvent for the plastic and a material having a high specific surface area are mixed together.
  • the plastic consists of a prefabricated powder of a mixture of the plastic and the material with the high specific surface, wherein the mixing of all components is carried out by kneading.
  • WO 2010/023450 A1 discloses an explosive mixture which comprises, among other things, a chlorinated rubber as binder.
  • DE 100 58 705 C1 describes a process for producing pourable plastic-bound explosive charges.
  • a crystalline explosive is embedded in a polymer matrix of a binder, a plasticizer and other excipients. Over a given mixing ratio, the pourability is maintained despite a high solids content.
  • the invention has the object to show a structurally simple way to save weight in a hand grenade, a projectile, ammunition, etc.
  • the invention is based on the idea, through the use of chlorinated rubber matrices, to provide plastic-bound explosive formulations which, due to the high water and water vapor resistance of chlorinated rubber, the production of functional shellless hand grenades or hand grenades and ammunitions with a greatly reduced on the total weight Envelop allow.
  • the chloro rubber matrix has the advantage over other binder matrices customary in explosive formulations that they have, for example, B. has a number of polybrominated organic compounds flame retardant properties.
  • B. has a number of polybrominated organic compounds flame retardant properties.
  • the plastic-bound explosive formulations proposed here have matrices of a chlorinated rubber, a plasticizer or plasticizer mixture and, if appropriate, a further binder of more than 20% by weight in total for the production of explosive compacts to be used without casing.
  • the plastic matrix content of more than 20% by weight ensures that the sensitivity of the shellless applications (hand grenades or, for example, pioneer-type explosive agents) is comparable or better than that of corresponding enveloped applications.
  • An explosive formulation having the above features includes, for example
  • the proportion of the plastic matrix of chlorinated rubber, plasticizer or plasticizer mixture and optionally a further binder of the plastic-bound explosive formulations proposed here is expressly not limited to a total of more than 20% by weight.
