Abstract
Vorliegende Erfindung befaßt sich mit Anzündsätzen auf Basis von Oxidationsmitteln und Initialexplosivstoffen. Sie enthalten als Oxidationsmittel Zinkperoxid und als Initialexplosivstoffe Diazodinitrobenzol und/oder Strontiumsalze des Mono- und/oder Dinitrodihydroxidiazobenzols. Entsprechend dem Gehalt an den eingesetzten Strontiumsalzen können die Sätze auch mit geringer Verdämmung eingesetzt werden, bzw. kann diese beliebig gewählt werden. Die Sätze zeichnen sich weiterhin durch blei- und bariumfreie Verbrennungsprodukte aus, so daß sie die gesundheitsgefährdenden Eigenschaften der bisher bekannten Anzündsätze nicht aufweisen.The present invention is concerned with primers based on oxidizing agents and initial explosives. They contain zinc peroxide as the oxidizing agent and diazodinitrobenzene and / or strontium salts of mono- and / or dinitrodihydroxidiazobenzene as initial explosives. Depending on the content of the strontium salts used, the sets can also be used with low insulation, or this can be chosen as desired. The sentences are furthermore characterized by lead and barium-free combustion products, so that they do not have the health-endangering properties of the previously known ignition charges.
Description
Gegenstand der vorliegenden Anmeldung sind Anzündsätze mit verminderter Schadstoffemission. Besonders die Emission von Blei und seinen Verbindungen ist in diesen Sätzen vollkommen ausgeschlossen, da sie keine Bleiverbindungen enthalten. Zusätzlich lassen sich diese Sätze bei variabler Verdämmung einsetzen.The subject of the present application are primers with reduced pollutant emissions. In particular, the emission of lead and its compounds is completely excluded in these sets, since they contain no lead compounds. In addition, these sets can be used for variable insulation.
Die bekannten Anzündsätze enthalten als Initialexplosivstoffe Bleisalze, die sich von Di- und Trinitroresorcin, Trinitrophenolen oder der Stickstoffwasserstoffsäure ableiten. Darüber hinaus sind auch Anzündsätze bekannt, die Doppelsalze des Bleis, z.B. Bleinitrathypophosphit, enthalten.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.
Beim Abbrand dieser Aozundsätze treten in den zur Verminderung der Lärmemission in vermehrtem Umfang neu installierten geschlossenen Schießständen erhöhte Konzentrationen an Blei und seinen Verbindungen in der Umgebungsluft auf, die oft die zulässigen Konzentrationen überschreiten können. Die zulässige Konzentration liegt für Blei zur Zeit bei 0,1 mg/m3. Diese Konzentration kann in ungünstigen Fällen bereits nach einer geringen Schußzahl erreicht werden.When these firing charges burn off, increased concentrations of lead and its compounds in the ambient air, which are often the permissible ones, appear in the closed shooting ranges newly installed to reduce noise emissions Concentrations can exceed. 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.
Analoges gilt für den Bariumgehalt von Anzündsätzen. Barium verbindungen werden in den Anzündmitteln oft als Oxidations stoffe in Form von Bariumnitrat oder Bariumperoxid einge-setzt, die nach dem Abbrand ebenfalls die Luft verunreinigen und eine Gesundheitsgefährdung des Schießpersonals in den genannten Schießständen mit sich bringen.The same applies to the barium content of ignition charges. 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.
Es bestand deshalb die Aufgabe, Anzündsätze zu entwickeln, die nach ihrem Abbrand keine gesundheitsgefährdenden Emissionen in Form von Blei- und Bariumverbindungen entwickeln. Weiterhin sollen die neuen Anzündsätze bei variabler Verdämmung einsetzbar sein.It was therefore the task to develop ignition kits which, after they burned up, do not produce any harmful emissions in the form of lead and barium compounds. Furthermore, the new primers should be usable with variable insulation.
In Erfüllung dieser Aufgabe wurden nun Anzündsätze aus Initialexplosivstoffen im Gemisch mit Oxidationsmitteln gefunden, die dadurch gekennzeichnet sind, daß sie als Initialexplosivstoffe Diazodinitrophenol und/oder Strontium salze des Mono- und/oder Dinitrodihydroxidiazobenzols und als Oxidationsmittel Zinkperoxid enthalten.In fulfilling this task, 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.
Überraschenderweise lassen sich die erfindungsgemäßen Anzündsätze, selbst wenn sie Diazodinitrophenol als Initialex plosivstoff enthalten, mit keiner, oder nur einer schwachen Verdämmung einsetzen. Solche Diazodinitrophenol-Zinkperoxid Anzündsätze eignen sich besonders gut für die stark eigenverdämmten AmboB-Zündhütchen-Systeme, obwohl das Diazodinitrophenol nur eine geringe Schüttdichte besitzt, die dem Einsatz dieser Verbindung in Anzündsätzen bisher entgegenstand. In Anzündsystemen mit geringerer Eirenverdämmung oder in denen die Verdichtung des Diazodinitrophenols (Diazol) nicht für eineSurprisingly, 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. Such 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
vollständige Anzündung ausreicht, wird das Diazol teilweise oder vollständig durch die Strontiumsalze des Mono- oder Dinitrodihydroxidiazobenzols, das im folgenden auch als Strontiumdiazinat bezeichnet wird, ersetzt. Durch Variation des Diazinatgehalts ist es also möglich, Anzündsätze herzustellen, die bei jeder gewünschten Verdichtung oder Verdämmung eine vollständige Anzündung ermöglichen.complete ignition is sufficient, the diazole is partially or completely replaced by the strontium salts of mono- or dinitrodihydroxidiazobenzene, also referred to below as strontium diazinate. By varying the diazinate content, it is possible to produce primer sets that allow complete ignition at any compression or insulation.
Der Anteil des Gemischs Diazol/Diazinat in den erfindungsgemäßen Anzündsätzen kann zwischen 10 und 70 Gew.-% schwanken, je nachdem, für welchen Zweck der Satz eingesetzt wird. Dabei können die beiden Bestandteile im beliebigen Verhältnis zueinander stehen; gegebenenfalls kann auch einer dieser beiden Initialexplosivstoffe in dem Satz vollständig fehlen.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.
Die erfindungsgemäß eingesetzten Diazinate werden in der DE-OS 28 06 599 beschrieben. Dort werden auch Verfahren zu ihrer Herstellung angegeben. Die Verbindungen selbst sollten nur zusammen mit geeigneten Passivatoren gehandhabt werden. Dies gilt besonders für das Kaliumsalz, das ohne Mitverwendung eines geeigneten Passivators nicht eingestell werden darf. Als Passivator für das Strontiumsalz empfiehlt sich Strontiumsulfat oder Strontiumoxalat.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.

Strontium sulfate or strontium oxalate is recommended as a passivator for the strontium salt.
