Definitions

  • the invention relates to a primer and its use.
  • combustion residues of lead and barium compounds used in ignition charges for example lead styphnate as initial explosive and barium peroxide as oxidizing agent, have the disadvantage that they are toxic and ecologically questionable.
  • the poor tribological properties of the combustion residues of barium peroxide reduce the operability of the weapon or the bolt thruster.
  • the lead styphnate could easily be replaced, for example, by diazodinitrophenol or salts of dinitrobenzofuroxanate
  • the zinc peroxide proposed in EP-AO 031 045 as a substitute for barium peroxide is far less harmful or ecologically harmful, but its combustion residues also have a corrosive and functional inhibiting effect on the materials of the weapon or the bolt thruster.
  • Object of the present invention is to provide a Anzündsatz that overcomes the disadvantages of the prior art, which is lead and barium free, which has a high reliability and / or its combustion residues do not lead to a malfunction of the weapon or the bolt thruster.
  • the object is achieved by a lead-free and barium-free ignition charge which contains no oxidizing agent, in particular no peroxide.
  • the primer composition according to the invention may optionally contain one or more additives.
  • the subject matter of the invention is a lead-free and barium-free ignition charge without oxidizing agent, which contains an initial explosive or several initial explosives.
  • this primer may contain boron and / or boron derivatives.
  • the ignition charge can be used, for example, in cartridges with edge firing or cartridges for industrial purposes, again, for example, for bolt thrusters or cattle stunning.
  • Oxidizing agents in the context of the invention are understood to be substances whose oxygen balance is positive.
  • examples of such substances are the nitrates of the alkali and / or alkaline earth metals and / or ammonium, the perchlorates of the alkali and / or alkaline earth metals and / or ammonium, the peroxides of the alkaline earth metals and / or zinc or mixtures of two or more of these substances.
  • an ignition charge which, in addition to the initial explosive, sensitizer and friction agent and optionally one or more additives, additionally contains a boron component, for example boron and / or boron derivatives such as boron nitride and / or zirconium boride.
  • a boron component for example boron and / or boron derivatives such as boron nitride and / or zirconium boride.
  • boron component for example boron and / or boron derivatives such as boron nitride and / or zirconium boride.
  • boron or boron derivatives in igniter charges is known per se, for example from WO-A-0140144.
  • boron or boron derivatives are always used in conjunction with oxidizing agents in the prior art and serve as reducing agents relative to these oxidizing agents.
  • the boron or boron derivatives therefore do not contribute in these igniter compositions to improve the tribological properties of the combustion residues.
  • the boron component it is particularly preferred according to the invention for the boron component to be used as a builder of metal boron oxides in a stoichiometric amount, based on the formation of alkali and / or alkaline-earth borates in the combustion residues.
  • the primer composition contains, in addition to initial explosive, sensitizer and friction agent and optionally one or more additives, a boron component, for example boron and / or boron derivatives such as boron nitride and / or zirconium boride, one or more substances which are used to improve and
