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. Ignition charges are also known, the double salts of lead, e.g. Lead nitrate hypophosphite.
- Barium compounds in the oxidation of ignition often as materials in the form of barium nitrate or barium peroxide, a g e-sets, the after burning also contaminate the air and bring health hazards of the shooting staff in said shooting ranges with it.
- primers from initial explosives in a mixture with oxidizing agents have now been found, which are characterized in that they contain diazodinitrophenol and / or strontium salts of mono- and / or dinitrodihydroxidiazobenzene as initial explosives and zinc peroxide as an oxidizing agent.
- the primers according to the invention even if they contain diazodinitrophenol as an initial explosive, can be used with no or only a slight insulation.
- diazodinitrophenol-zinc peroxide primers are particularly well suited for the highly self-insulated AmboB primer systems, although the diazodinitrophenol has only a low bulk density, which previously prevented the use of this compound in primers. In ignition systems with less eiren insulation or in which the compression of the diazodinitrophenol (diazole) is not for one
- the diazole is partially or completely replaced by the strontium salts of mono- or dinitrodihydroxidiazobenzene, also referred to below as strontium diazinate.
- strontium diazinate By varying the diazinate content, it is possible to produce primer sets that allow complete ignition at any compression or insulation.
- the proportion of the mixture of diazole / diazinate 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.
- the two components can be in any relation to each other; if necessary, one of these two initial explosives may also be completely missing from the set.
- the diazinates used according to the invention are described in DE-OS 28 06 599. Methods for their production are also specified there. The connections themselves should only be handled together with suitable passivators. This applies particularly to the potassium salt, which must not be adjusted without the use of a suitable passivator. Strontium sulfate or strontium oxalate is recommended as a passivator for the strontium salt.
- 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 29 52 069.
- the amount of zinc p eroxid in the ignition charges according to the invention may vary between 10 and 70 wt .-%.
- the zinc peroxide can be used both in fine-grained condition and coarse-grained. Fine grain zinc peroxide with an average grain size of approx. 10 ⁇ m is preferably used when the primers are used as compressed charges, while coarse-grained zinc peroxide with an average grain size of around 30 ⁇ m is particularly suitable for less densely compressed charges, eg in rimfire sets.
- the ignition charges according to the invention can 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. Metal powder from titanium, zirconium, magnesium, cerium magnesium, cerium silicon or aluminum-magnesium alloys.
- Some reducing agents can also perform the function of a friction agent at the same time, e.g. 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 nitrocellulose or pentaerythritol tetranitrate.
- octogen and amino compounds of nitrated aromatics, for example trinitrobenzene, such as mono-, di- or triaminotrinitrobenzene or diaminohexanitrodiphenyl, 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 hexanitrodiphenylamine, and also 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, and the passivators already mentioned above.
- the proportion of the inert substances in the primers according to the invention can be 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 that is used, for example, in the Anvil primers 4.45 mm can be loaded advantageously with good self-insulation.
- a mixture of 5 parts by weight of tetrazene, 20 parts by weight of diazole, 50 parts by weight of fine-grained zinc peroxide, 5 parts by weight of titanium powder and 20 parts by weight of dibasic ball powder with 22 parts by weight of water is homogenized and by Spread dosed into perforated plates. After loading in primer caps, the capsule is dried, densified and the primer cap is completed. Sensitivity and bombardment results are comparable to those of a known kindling.
- This example describes an ignition charge that e.g. can be loaded in propellant cartridges 6,8 / 11 with low self-insulation.
- Sensitivity and driving performance correspond to that of conventional ammunition.
