Definitions

  • the present invention is a pyrotechnic igniter.
  • Pyrotechnic igniters in the context of the invention are substances or mixtures which can develop a pyrotechnic effect.
  • the subject of the present invention is a pyrotechnic igniting agent which can be used in mechanical, electrical or opto-electric ignition systems.
  • a 5,5'-azotetrazolate explosive which comprises an iron, cobalt, nickel, copper, cadmium or guanyl urea salt of a 5,5'-azotetrazole or a mixture of at least one 5,5'-azotetrazolate and at least one bistetrazolyl triazenate or at least one further metal salt or guanyl urea salt of a 5,5'-azotetrazole.
  • the salts described therein are neutral, ie neither acidic nor basic.
  • Zinc and chromium salts of 5,5'-azotetrazole are according to the document DE 102010025104 A1 not storable.
  • tetracene-containing pyrotechnic mixtures are thermally not sufficiently stable, since tetrazene decomposes already at 120 ° C.
  • DE 10 2010 036 950 A1 discloses the use of basic 5,5'-azotetrazolate salts of general formula ([ML m X n ] p + ) q (C 1 N 4 R 1 - ) r , where M is an element of the third-twelfth group of the periodic table in the range of 21-80, as initial explosive.
  • the object of the present invention was to provide a further pyrotechnic igniter.
  • Another object of the present invention was to provide a pyrotechnic igniter which can be used in mechanical, electrical or opto-electric ignition systems.
  • this object is surprisingly achieved by the features of the main claim.
  • novel basic azotetrazolate compounds according to the invention have defoaming temperatures in the range from 180 ° C to 240 ° C, friction sensitivities of 0.1 N to 1.0 N and impact sensitivity of 0.1 J to 0.5 J.
  • the pyrotechnic igniter is one which contains as an additive 10 to 60 wt .-% of an oxidizing agent selected from one or more of 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 the ammonium, the peroxides of the alkali and / or alkaline earth metals and / or zinc.
  • an oxidizing agent selected from one or more of 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 the ammonium, the peroxides of the alkali and / or alkaline earth metals and / or zinc.
  • the pyrotechnic igniting agent contains as additive 0 to 10 wt .-% of a sensitizer, preferably tetracene.
  • the pyrotechnic igniting agent according to the invention preferably contains as an additive 0 to 20 wt .-% of a reducing agent selected from one or more of aluminum, antimony sulfide, calcium silicide, titanium, titanium hydride, boron, borohydride, zirconium, zirconium hydride, silicon, graphite, activated carbon, carbon black or Friction agent preferably glass breakage.
  • a reducing agent selected from one or more of aluminum, antimony sulfide, calcium silicide, titanium, titanium hydride, boron, borohydride, zirconium, zirconium hydride, silicon, graphite, activated carbon, carbon black or Friction agent preferably glass breakage.
  • the pyrotechnic igniting agent contains as additive 0.1 to 5 wt .-% of a binder selected from one or more of cellulose and derivatives thereof, polyvinyl butyrals, Polynitropolyphenylen, Polynitrophenylether, Plexigum, polyvinyl acetate and copolymers.
  • a binder selected from one or more of cellulose and derivatives thereof, polyvinyl butyrals, Polynitropolyphenylen, Polynitrophenylether, Plexigum, polyvinyl acetate and copolymers.
  • the pyrotechnic igniting agents according to the invention are used in mechanical, electrical or opto-electric ignition systems.
  • the substances are characterized by lead and barium freedom, a high ignition power, short reaction times and corresponding sensitivities. These features enable a reduction in the mass of explosives needed for safe ignition.
  • Table 1 shows decomposition temperatures, friction and impact sensitivities of selected examples.
  • the measurement of the friction and impact sensitivities was carried out according to methods of the Federal Institute for Materials Research (BAM) in the BAM Report 142 (1987), while the measurement of the decomposition temperatures by differential scanning calorimetry (DSC) (Mettler) at a heating rate of 10 K. per minute took place.
  • BAM Federal Institute for Materials Research
  • DSC differential scanning calorimetry
  • Table 1 lists the compositions of 5 different basic salts of 5,5'-azotetrazole. ⁇ b> Table 1 ⁇ / b> Compositions, deflagration temperatures and friction and impact sensitivities of selected basic salts of 5,5'-azotetrazole. No. Molecular formula T Verp .
