Definitions
- the invention relates to ignition charges with initial explosives or primary explosives selected from the group consisting of compounds of lead derived from Trinitropolyphenolen such as trinitrophenol, trinitroresorcinol or hydrazoic acid, in admixture with oxygen-providing substances having an improved ignition performance, especially at low temperatures ,
- the ignition charges are intended to ensure the ignition of gunpowder in shooting and military cartridges (cartridges).
- a flame is generated in all devices with annular or central percussion under the action of a firing pin with the aid of an initial explosive, igniting the propellant.
- ignition of the Initialexplosivstoffes can also be done by means of an electrically generated thermal pulse.
- mercury fulminate based primer compositions are virtually no longer used because of their high toxicity and lack of thermal stability. They have been replaced by compositions containing lead, antimony and barium compounds.
- a disadvantage of the known igniter charges is that their ignitability decreases sharply at low temperatures, in particular below -35.degree.
- the present invention provides primer compositions with initial explosives in admixture with oxygen-supplying substances which have an improved ignitability at temperatures below -35 ° C. in comparison with the known igniter compositions.
- the object is achieved by primer as defined in claim 1.
- the ignition charges according to the invention have an ignition capability which is improved over the prior art at temperatures below -35 ° C., in particular up to -54 ° C.
- the initial explosives are preferably used in a total amount of from 30 to 60% by weight, based on the total mixture.
- oxygen-supplying substances in addition to the metal peroxide zinc peroxide known per se from the prior art, it is also possible to use further oxygen-supplying substances.
- the primer example can be used in the primer example: lead dioxide, tin dioxide, ceria tungsten trioxide and / or nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyandiamidine and the elements sodium, potassium, magnesium, calcium, cerium, especially potassium nitrate or basic cerium nitrates.
- the amount of oxygen-providing substances in the novel igniter compositions can vary between 40 and 70% by weight, based on the total mixture.

Description
Die Erfindung betrifft Anzündsätze mit Initialexplosivstoffen oder Primärsprengstoffen ausgewählt aus der Gruppe bestehend aus Verbindungen des Bleis, die sich von Trinitropolyphenolen, wie beispielsweise Trinitrophenol, Trinitroresorcin oder der Stickstoffwasserstoffsäure ableiten, im Gemisch mit Sauerstoff-liefernden Substanzen, die eine verbesserte Anzündleistung insbesondere bei tiefen Temperaturen besitzen.The invention relates to ignition charges with initial explosives or primary explosives selected from the group consisting of compounds of lead derived from Trinitropolyphenolen such as trinitrophenol, trinitroresorcinol or hydrazoic acid, in admixture with oxygen-providing substances having an improved ignition performance, especially at low temperatures ,
Die Anzündladungen sind dazu bestimmt, die Entzündung von Schießpulvern in Schieß- und Militär-Kartuschen (-Patronen) zu gewährleisten. Dabei wird in allen Vorrichtungen mit ringförmiger oder zentraler Percussion unter der Einwirkung eines Schlagbolzens mit Hilfe eines Initialexplosivstoffes eine Flamme erzeugt, die den Treibsatz zündet. Weiterhin kann Anzündung des Initialexplosivstoffes auch mit Hilfe eines elektrisch erzeugten thermischen Impulses erfolgen.The ignition charges are intended to ensure the ignition of gunpowder in shooting and military cartridges (cartridges). In this case, a flame is generated in all devices with annular or central percussion under the action of a firing pin with the aid of an initial explosive, igniting the propellant. Furthermore, ignition of the Initialexplosivstoffes can also be done by means of an electrically generated thermal pulse.
Heutzutage werden Zündladungs-Zusammensetzungen auf Basis von Quecksilberfulminat im Wesentlichen wegen ihrer starken Toxizität und ihres Mangels an thermischer Stabilität praktisch nicht mehr verwendet. Sie wurden durch Zusammensetzungen ersetzt, die Blei-, Antimon- und Bariumverbindungen enthalten.Today, mercury fulminate based primer compositions are virtually no longer used because of their high toxicity and lack of thermal stability. They have been replaced by compositions containing lead, antimony and barium compounds.

Es wurde überraschend gefunden, dass durch Zusatz von Kalium-dinitrobenzofuroxanat zu wohlbekannten Anzündsatzrezepturen basierend auf Blei-trinitroresorcinat die Anzündleistung insbesondere bei tiefen Temperaturen deutlich gesteigert wird, dies verbreitert den Einsatzbereich von Patronen unterschiedlicher Kaliber deutlich.It has surprisingly been found that by adding potassium dinitrobenzofuroxanate to well-known primer formulations based on lead trinitroresorcinate, the ignition performance is markedly increased, especially at low temperatures, which clearly widens the range of use of cartridges of different calibers.
