Definitions

  • the subject of the present application are primers with reduced pollutant emissions.
  • the emission of lead and its compounds is completely excluded in these sets, since they contain no lead compounds.
  • these sets can be used for variable insulation.
  • the known ignition charges contain lead salts as initial explosives, which are derived from di- and trinitroresorcinol, trinitrophenols or hydrochloric acid.
  • primer charges are known, d 'ie double salts of lead, for example.
  • the permissible concentration for lead is currently 0.1 mg / m 3 . In unfavorable cases, this concentration can be achieved after a small number of shots.
  • Barium compounds are often used in the igniters as oxidants in the form of barium nitrate or barium peroxide, which also contaminate the air after burning and pose a health risk to the shooting personnel in the shooting ranges mentioned.
  • primers from initial explosives in a mixture with zinc peroxides as oxidizing agents have now been found, which are characterized in that they contain, as initial explosives, strontium salts of mono- and / or dinitrodihydroxidiazobenzene in proportions between 5 and 70% by weight in a mixture with passivators and additionally still tetrazene in amounts up to 30% by weight and zinc peroxide in amounts between 10 and 70% by weight. each based on the total mixture.
  • the primers according to the invention can be used with little or no insulation.
  • the proportion of the initial explosive in the ignition kits according to the invention can vary between 10 and 70% by weight, depending on the purpose for which the kit is used.
  • Zinc peroxide is used as the oxidizing agent in the ignition kits according to the invention. This preferably has an active oxygen content of more than 12.3%. The production of such zinc peroxide is described in DE-PS 3029 52 069.
  • the amount of zinc peroxide in the primers according to the invention can vary between 10 and 70% by weight.
  • Zinc peroxide can be used both in fine-grained condition and in coarse-grained form. Fine-grained zinc peroxide with an average grain size of approx. 10 J.l.m is preferably used when the primers are used as pressed charges, while coarse-grained zinc peroxide with an average grain size of about 30 microns for less densely compressed charges, e.g. B. in rimfire sets, is particularly suitable.
  • the ignition charges according to the invention contain tetrazene as an additional sensitizer up to an amount such that the tetrazene content in the total mixture is at most 30% by weight.
  • the primers according to the invention can also additionally contain reducing agents or other components which contribute to the implementation, as well as friction agents and other inert substances.
  • Suitable reducing agents are the reducing agents known per se in ignition kits, which improve the ignition ability and in some cases also increase the mechanical sensitivity.
  • Suitable substances are e.g. B. metal powder of titanium, zirconium, magnesium, cerium magnesium, cerium silicon or aluminum-magnesium alloys.
  • Some reducing agents can also perform the function of a friction agent, such as. B. antimony sulfides or calcium silicides.
  • the proportion of reducing agents in the ignition charge can be 0 to 10% by weight.
  • Friction agents which do not take part in the reaction during the combustion can be present in amounts of up to 35% by weight in the primers according to the invention. Such friction agents are also known per se. Glass powder may be mentioned as an example.
  • secondary explosives are suitable, such as. B. nitrocellulose or pentaerythritol tetranitrate.
  • Another example is octogen, and amino compounds of nitrated aromatics, e.g. B. of trinitrobenzene, such as mono-, di- or triaminotrinitrobenzene or diaminohexanitrodiphenyl, continue the acylation products of these compounds, such as. B. hexanitrooxanilide or hexanitrodiphenylurea.
  • These secondary explosives also include, for example, hexanitrostilbene, hexanitrodiphenyl oxide, hexanitrodiphenyl sulfide, hexanitrodi phenylsulfone and hexanitrodiphenylamine as well as tetranitrocarbazole, tetranitroacridone or polyvinyl nitrate.
  • the proportion of these substances in the ignition charge can amount to 0 to 30% by weight.
  • Suitable as inert substances are the substances known per se in ignition systems, which are often also used to match the properties of these phrases to the respective intended use. Tin dioxide is an example.
  • the inert substances also include binders, adhesives and dyes as well as the passivators already mentioned above.
  • the proportion of the inert substances in the primers according to the invention can vary between 0 and 20% by weight.
  • the primers according to the invention are produced by methods known per se by sieving the dry or kneading the water-moist mixture.
  • the water-moist mass can be dosed by brushing into perforated plates or by extrusion.
  • This example describes an ignition charge, e.g. B. in propellant cartridges 6,8 / 11 can be loaded advantageously with low self-insulation.
  • Sensitivity and driving performance correspond to that of conventional ammunition.
