Abstract
Die Erfindung betrifft ein folienförmiges Anzündelement, insbesondere zum Anzünden der Treibladung großkalibriger Munition. Die Erfindung bezieht sich ferner auf ein Verfahren zur Herstellung eines derartigen Anzündelementes. DOLLAR A Um zu erreichen, daß das Anzündelement trotz großer Reproduzierbarkeit des Abbrandverhaltens einfach und kostengünstig herstellbar ist, schlägt die Erfindung vor, als Material für das Anzündelement im wesentlichen nur Schwarzpulver, Nitrocellulose und einen Weichmacher als Binder zu verwenden, wobei der Anteil des Schwarzpulvers > 60 Gew.-%, vorzugsweise 63 bis 85,5 Gew.-%, der Anteil der Nitrocellulose < 10 Gew.-%, vorzugsweise 2,8 bis 7 Gew.-%, und der Anteil des Binders >= 5 Gew.-%, vorzugsweise 5,0 bis 30 Gew.-%, beträgt.The invention relates to a film-shaped ignition element, in particular for igniting the propellant charge of large-caliber ammunition. The invention further relates to a method for producing such an ignition element. DOLLAR A In order to achieve that the igniter element can be produced simply and inexpensively despite the high reproducibility of the burning behavior, the invention proposes to use essentially only black powder, nitrocellulose and a plasticizer as a binder for the igniter element, the proportion of black powder being> 60% by weight, preferably 63 to 85.5% by weight, the proportion of nitrocellulose <10% by weight, preferably 2.8 to 7% by weight, and the proportion of binder> = 5% by weight %, preferably 5.0 to 30% by weight.
Description
Die Erfindung betrifft ein folienförmiges Anzündelement, insbesondere zum Anzünden der Treibladung großkalibriger Munition. Die Erfindung bezieht sich ferner auf ein Verfahren zur Herstellung eines derartigen Anzündelementes.The invention relates to a film-shaped ignition element, especially for lighting the large-caliber propellant charge Ammunition. The invention further relates to a method for Production of such an ignition element.
Aus der
Um ein für den Anzündvorgang des Treibladungspulvers erforderliches reproduzierbares Abbrandverhalten zu erhalten, ist bei Sprengfolien ein außerordentlich hoher Fertigungsaufwand erforderlich. Denn da der jeweilige Anzündverstärker den Abbrand der entsprechenden Treibladung steuert, führen bereits kleine Abweichungen beim An- und Abbrand des Anzündverstärkers zu relativ großen Änderungen des Maximalgasdruckes der Treibladungsgase und somit auch zu entsprechenden Änderungen der Mündungsgeschwindigkeit des jeweiligen Geschosses.To one for the ignition process of the propellant powder to obtain the required reproducible combustion behavior with explosive foils an extraordinary high manufacturing effort required. Because since the respective ignition amplifier Burning of the corresponding propellant charge already leads small deviations in the ignition and combustion of the ignition amplifier to relatively large changes the maximum gas pressure of the propellant gases and therefore also for corresponding changes the muzzle velocity of the respective floor.
Der Erfindung liegt die Aufgabe zugrunde, ein folienförmiges Anzündelement der eingangs erwähnten Art anzugeben, welches trotz großer Reproduzierbarkeit des Abbrandver haltens einfach und kostengünstig herstellbar ist und vollständig verbrennt. Die Erfindung soll ferner ein Verfahren zur Herstellung eines derartigen Anzündelementes offenbaren.The invention is based on the object foil-shaped ignition the one mentioned at the beginning Specify which, despite the high reproducibility of the Abbrandver is simple and inexpensive to manufacture and completely burns. The invention is also intended to provide a method for producing such ignition element reveal.
Erfindungsgemäß wird diese Aufgabe hinsichtlich des folienförmigen Anzündelementes durch die Merkmale des Anspruchs 1 und hinsichtlich des Verfahrens durch den Anspruch 7 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.According to the invention, this object is achieved with regard to of the film-shaped ignition element by the features of claim 1 and with regard to the method solved by claim 7. Reveal further, particularly advantageous embodiments of the invention the subclaims.
Die Erfindung beruht im wesentlichen auf dem Gedanken, ein folienförmiges Anzündelement mit einer im Verhältnis zu Sprengfolien wesentlich langsameren Abbrandgeschwindigkeit zu verwenden, deren Lebhaftigkeitskennwert L30-80 zwischen 0,1 und 0,3 liegen soll. Dieses wird dadurch erreicht, daß das Material der Anzündfolie im wesentlichen aus Schwarzpulver, Nitrocellulose und einem Weichmacher als Binder besteht, wobei der Anteil des Schwarzpulvers > 60 Gew.%, vorzugsweise 63 bis 85,5 Gew%, der Anteil der Nitrocellulose < 10 Gew.%, vorzugsweise 2,8 bis 7 Gew%, und der Anteil des Binders ≥ 5 Gew.%, vorzugsweise 5,0 bis 30 Gew.%, beträgt.The invention is essentially based on the idea of using a film-shaped ignition element with a burning rate that is considerably slower than that of explosive films, the liveliness characteristic value L 30-80 of which should be between 0.1 and 0.3. This is achieved in that the material of the ignition film consists essentially of black powder, nitrocellulose and a plasticizer as a binder, the proportion of black powder> 60% by weight, preferably 63 to 85.5% by weight, the proportion of nitrocellulose <10% by weight .%, preferably 2.8 to 7% by weight, and the proportion of the binder is ≥ 5% by weight, preferably 5.0 to 30% by weight.
Um insbesondere weiche und biegsame Folien zu erhalten, die sich z.B. direkt um das in der Patrone befindliche Anzündrohr wickeln lassen, haben sich als Binder (Weichmacher) insbesondere Bis(-12-ethylhexyl)-phthalat, Dimethyl-phthalat, Edenol B 33 und Butyl-NENA bewährt.To be particularly soft and pliable To obtain foils that e.g. right around the one in the cartridge ignition tube have been used as binders (plasticizers), in particular bis (-12-ethylhexyl) phthalate, Dimethyl phthalate, Edenol B 33 and Butyl-NENA proven.
Die Wandstärke des Anzündelementes sollte zwischen 0,3 und 2,0 mm, vorzugsweise zwischen 1 und 1,5 mm, liegen.The wall thickness of the igniter should be between 0.3 and 2.0 mm, preferably between 1 and 1.5 mm.
Zur Herstellung der Anzündelemente kann die Nitrocellulose zunächst mit dem Schwarzpulver trocken vermischt und danach der Binder zusammen mit einem Lösemittelgemisch zugegeben werden. Es kann allerdings auch zunächst die Nitrocellulose mit dem Lösemittelgemisch versetzt und danach das Schwarzpulver und der Binder zugemischt werden. Als Lösemittel hat sich eine Mischung aus 20 Gew.% Methanol und 50 Gew.% Aceton bewährt, wobei die Gewichtsprozentangaben der Anteile des Lösemittels sich jeweils auf das Gesamtgewicht des verwendeten Schwarzpulvers, der verwendeten Nitrocellulose und des Binders bezieht.For the production of the ignition elements can the nitrocellulose first mixed dry with the black powder and then the binder together with a solvent mixture be added. However, the nitrocellulose can also be used first Solvent mixture added and then the black powder and the binder mixed become. As a solvent has a mixture of 20 wt.% methanol and 50 wt.% acetone proven, where the percentages by weight of the proportions of the solvent the total weight of the black powder used, the nitrocellulose used and the binder.
Nach Durchmischung dieses Ansatzes wird die entsprechende Masse dann z.B. in einer entsprechenden Form verteilt und durch Erwärmung, bei welcher das Lösemittel entweicht, getrocknet.After mixing this approach the corresponding mass is then e.g. in an appropriate form distributed and by warming, where the solvent escapes, dried.
