Definitions
- the invention relates to lead and barium-free primers with initial explosives in a mixture with oxygen-supplying substances.
- primers contain, as initial explosives, compounds, in particular lead, which are derived from trinitropolyphenols, such as trinitrophenol, trinitroresorcinol or hydrochloric acid. Furthermore igniters are also known which contain double salts of lead, for example hypophosphite nitrate. When these firing charges burn, there are increased concentrations of lead and its compounds in the ambient air, which reach the permissible limit concentrations after a small number of shots. Solutions have already been proposed which consist of initial explosives which are free of heavy metals. Diazodinitrophenol in particular has established itself as such.
- the primers containing diazodinitrophenol for example with zinc peroxide as the oxygen-supplying substance, show very strong gas pressure surges which are caused by the violently reacting diazodinitrophenol. This can lead to malfunctions in the function of the weapon or inside and outside ballistics.
- diazodinitrophenol shows an increased thermal reactivity.
- the present invention thus relates to improved lead and barium-free primers with initial explosives in a mixture with oxygen-providing substances.
- a first embodiment for solving the above-mentioned problem therefore consists in lead and barium-free primers with initial explosives in a mixture with oxygen-supplying substances, which are characterized in that the initial explosives from alkali metal and / or alkaline earth metal salts of dinitrobenzofuroxanes and the oxygen - Providing substances from metal peroxides, nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyandiamidine and the elements sodium, potassium, magnesium, calcium, cerium and / or polyvalent metal oxides are selected.
- the igniter charges according to the invention have an improved stability compared to the prior art when stored in a moist / warm environment.
- the initial explosives are preferably used in a proportion of 5 to 70% by weight, in particular 30 to 60% by weight, based on the mixture as a whole.
- oxygen-providing substances can also be used as oxygen-providing substances.
- other substances in this sense that can be used in the primer are: tin dioxide, cerium dioxide, tungsten trioxide and / or nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyandiamidine and the elements sodium, potassium, magnesium, calcium, cerium, in particular potassium nitrate or basic cerium nitrate.
- the amount of oxygen-supplying substances in the ignition kits according to the invention can vary, for example, between 5 and 70% by weight, based on the mixture as a whole.
- a quantity of 8 to 60% by weight of the oxygen-supplying substances is particularly preferred for the purposes of the invention.
- the substance can be used both in fine-grained state and in coarse-grained form. Fine-grained substances with an average grain size of approx. 10 ⁇ m are preferably used when the primers are used as compressed charges, while coarse-grained substances with a grain size of approx. 30 ⁇ m are particularly suitable for less densely compressed charges, for example in rimfire sets.
- sensitizers preferably Tetrazene
- proportions of 0 to 30% by weight, based on the total mixture can be present.
- Suitable substances are preferably selected from carbon and / or metal powders, in particular boron, aluminum, cerium, titanium, zirconium, magnesium and silicon, metal alloys, in particular cerium-magnesium, cerium-silicon, titanium-aluminum, aluminum-magnesium, calcium silicide and metal sulfides , in particular antimony sulfide and molybdenum sulfide and metal hydrides, for example titanium hydride, in particular in a proportion of 0 to 20% by weight, based on the total mixture.
- Some reducing agents can also perform the function of a friction agent, such as antimony sulfides or calcium silicides. While the proportion of reducing agents in the ignition charge can be 0 to 20% by weight, friction agents which do not take part in the reaction during the combustion can be present in amounts of up to 45% by weight, based on the mixture as a whole Ignition rates are available. Such friction means are known per se; glass powder is an example.
- Secondary explosives such as nitrocellulose or pentaerythritol tetranitrate, are particularly suitable as further components that make a contribution to the implementation.
- Other examples include octogen and hexogen, and amino compounds of nitrated aromatics, for example trinitrobenzene, such as mono-, di- or triaminotrinitrobenzene or aminohexanitrodiphenyl, and the acylation products of these compounds, such as hexanitrooxanilide or hexanitrodiphenylurea.
- These secondary explosives also include, for example, hexanitrostilbene, hexanitrodiphenyl oxide, hexanitrodiphenyl sulfide, hexanitrodiphenyl sulfone and hexanitodiphenylamine, and also tetranitrocarbazole, tetranitroacridone or Polyvinyl nitrate and nitrotriazolone and its compounds.
- the proportion of these substances in the ignition charge can amount to 0 to 30% by weight based on the total mixture.
- Suitable inert substances in the ignition sets according to the invention are substances known per se, which are often also used to match the properties of these sets to the respective intended use.
- binders, adhesives, dyes, passivators and / or agents for characterizing odors may be mentioned here, which can preferably be present in a proportion of 0 to 20% by weight, based on the mixture as a whole.
- examples include calcium carbonate, titanium dioxide and / or white boron nitride.
- the batch mixture or the binder as well as the batch cover can be supplemented with odor characterization agents which are suitable for withstanding the thermal load during the shot.
- vanillin fulfills these properties.
- 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 in the perforated plates or by extrusion.
- This example describes an ignition charge for an anvil primer with a charge mass of 20 mg.
- a mixture of 45 parts by weight of potassium dinitrobenzofuroxanate, 5 parts by weight of tetrazene, 30 parts by weight of zinc peroxide, 15 parts by weight of tin dioxide and 5 parts by weight of titanium was mixed with 22 parts by weight Homogenized water and dosed by brushing into perforated plates. After being placed in primers, it was dried and pressed.
- the igniter mixtures according to the invention showed better stability than a conventional igniter charge containing diazole in the course of 7 days when stored in a moist / warm manner at a temperature of 71 ° C. and an atmospheric humidity of 90%. When the sensitivity was examined, no ejection of the primer from the sleeves was observed.
- a water-moist mixture of 40 parts by weight of diazodinitrophenol, 15 parts by weight of tetrazene, 8 parts by weight of zinc peroxide, 35 parts by weight of glass powder (120 to 170 ⁇ m) and 2 parts by weight of adhesive * (adhesive) was thrown into rimfire tubes .221fB with a loading mass of 18 mg.
- the primer charge required a layer of lacquer consisting of 3 to 4 mg of Vinnapas * A50, which contained 0.2 mg of vanillin for characterizing the smell.
- the primer set ignited as a damper without a covering lacquer and achieved an inside and outside ballistics comparable to the usual ammunition.
