Description

Die Erfindung betrifft eine pyrotechnische Ladung als Nebel- oder als Brandsatz in Form von in einer Hülle angeordneten einzelnen Preßkörpern, gegebenenfalls mit einem Anzündsatz,und Verfahren zu ihrer Herstellung.The invention relates to a pyrotechnic charge as a smoke or as a fire in the form of individual pressed bodies arranged in a casing, optionally with an ignition charge, and a process for their production.

Es sind zahlreiche Arten von nebelerzeugenden Stoffen oder Stoffgemischen sowie Vorrichtungen, welche sie in ein oder über ein Zielgebiet verschießen, bekannt. üblicherweise werden die Nebelmischungen geformt und zu Preßkörpern verpreßt, in einer Metallhülse gestapelt und bei Zündung gegebenenfalls unter Verwendung eines Anzündsatzes aus der Hülsenöffnung ausgestoßen, wobei sie sich wie ein Schrotschuß kegelförmig verteilen.Numerous types of mist-producing substances or mixtures of substances and devices which fire them into or over a target area are known. The mist mixtures are usually shaped and pressed into compacts, stacked in a metal sleeve and, if ignited, are ejected from the sleeve opening, if necessary using an igniter, and are distributed conically like a shot.

Aus der DE-OS 19 13 790 ist eine Vorrichtung zur Erzeugung einer künstlichen Nebeldecke bekannt, in welcher die Preßkörper in einer berstsicheren Hülle um ein Zündrohr gestapelt sind. Diese Vorrichtung weist erhebliche Nachteile auf. So wird der Raum in der Hülle durch die in ihr gestapelten segmentierten Preßkörper nicht optimal genutzt. Vielmehr liegen Hohlräume vor, welche die Ladungsdichte vermindern. Außerdem entsteht insbesondere bei der Herstellung und beim Transport durch Abrieb an den Grenzflächen der Preßkörper ein erhöhter Staubanteil im Nebelsatz, der die Wirkung herabsetzende Materialverluste bewirkt. Schließlich ist auch der fertigungstechnische Aufwand sowohl zur Herstellung der segmentierten Preßkörper, als auch zu deren Einfügung in eine Ladungshülle unter Verwendung eines Zündrohres erheblich.From DE-OS 19 13 790 a device for generating an artificial fog blanket is known, in which the pressing bodies are stacked in a burst-proof envelope around an ignition tube. This device has considerable disadvantages. The space in the casing is therefore not optimally used due to the segmented pressing bodies stacked in it. Rather, there are cavities that reduce the charge density. In addition, an increased amount of dust in the mist set, which causes the effect of reducing material losses, arises in particular during manufacture and during transport due to abrasion at the interfaces of the pressed bodies. Finally, the manufacturing outlay is also considerable, both for producing the segmented pressing bodies and for inserting them into a charge envelope using an ignition tube.

Entsprechend aufgebaut sind bekannteBrandsätze.Known fire rates are structured accordingly.

Weitere Nachteile derartiger bekannter pyrotechnischer Ladungen resultieren aus dem Ausstoßprinzip. Da der Ausstoß der Preßkörper nur in einer Richtung erfolgt, ist zwangsläufig eine Begrenzung der Flächenbelegung vorgegeben. Die Flächenbelegung ist damit immer von der Ausstoßhöhe abhängig und kann bei schrotschußartiger Ausstoßung nicht variiert werden, was insbesondere bei Nebelsätzen nachteilig ist, aber auch bei Brandsätzen von Bedeutung sein kann.Further disadvantages of such known pyrotechnic charges result from the ejection principle. Since the pressing bodies are only ejected in one direction, a limitation of the area occupancy is inevitable. The area coverage is thus always usstoßhöhe from the A dependent can not be varied at shot-shot-like expulsion and what is particularly disadvantageous in fog sets, but may also be in incendiary important.

Ferner entsteht durch den Ausstoß in einer Richtung aufgrund der Reibung der Preßkörper entlang der Hülle ein weiterer Materialverlust. Außerdem sind die Einzelsegmente derart beschaffen, daß sie durch die bei der Zündung auftretende Druckbelastung teilweise zu kleinen Partikeln zerstört werden.Furthermore, there is a further loss of material due to the ejection in one direction due to the friction of the pressing bodies along the casing. In addition, the individual segments are designed in such a way that they are partially destroyed into small particles by the pressure load that occurs during ignition.

Ein weiterer Nachteil der bekannten Ladungen liegt in der zentralen Anordnung eines zusätzliche Kosten erzeugenden Siebrohres als Zündrohr, wodurch ein unmittelbarer Kontakt zwischen Anzündsäule und Nebelkörpern nicht gegeben ist.Another disadvantage of the known charges lies in the central arrangement of a sieve tube which generates additional costs as an ignition tube, which makes an immediate There is no contact between the igniter column and fog bodies.

Die meist aus Metall bestehende Hülle, aus welcher die Nebel- oder Brandsätze in einer bestimmten Höhe ausgestoßen werden, fällt anschließend unzerstört als ein Teil zu Boden und kann unter ungünstigen Umständen auch erhebliche Verletzungen hervorrufen.The shell, usually made of metal, from which the smoke or incendiary devices are ejected at a certain height, then falls undamaged as a part to the ground and can also cause considerable injuries under unfavorable circumstances.

Ein weiterer Nachteil der bekannten, als Nebelsatz verwendeten Ladungen rührt von der Zusammensetzung der Nebelmischungen her. Diese reagieren häufig sauer bzw. entwickeln Phosphorpentoxid, welches an der Luft zu Phosphorsäure umgesetzt wird, rufen Atembeschwerden und Hustenreiz hervor oder greifen innere Organe an. Derartige Nachteile sind besonders unerwünscht, wenn man an die Verwendung von Nebelladungen in Weinanbaugebieten zur Frostverhinderung oder bei Anwendung zu Ubungs- und Manöverzwecken denkt.Another disadvantage of the known charges used as a mist set comes from the composition of the mist mixtures. These often react acidic or develop phosphorus pentoxide, which is converted to phosphoric acid in the air, cause breathing difficulties and coughing or attack internal organs. Such disadvantages are particularly undesirable when one thinks of the use of fog loads in wine-growing areas to prevent frost or when used for exercise and maneuvering purposes.

Bekannt sind auch verschiedene Rauch- und Nebelmischungen. Beispielsweise wird in derDE-AS 24 51 701 ein Rauch- oder Nebelsatz beschrieben, der einen organischen Chlordonator, Metallpulver und/oder Metalloxid enthält. Der bekannte Nebelsatz enthält als Bindemittel mindestens einen der hochmolekularen Chlordonatoren Chlorparaffin, chloriertes Polyphenylen, chloriertes Polyphenoxyharz und Polyester aus Tetrachlorphthalsäure mit chloriertem Polyalkohol.Various smoke and fog mixtures are also known. For example, DE-AS 24 51 701 describes a smoke or mist set that contains an organic chlorine donor, metal powder and / or metal oxide. The known mist set contains at least one of the high molecular weight chlorine donors chloroparaffin, chlorinated polyphenylene, chlorinated polyphenoxy resin and polyester from tetrachlorophthalic acid with chlorinated polyalcohol as a binder.

Nachteilig bei diesen bekannten Nebelsätzen sind deren Hustenreiz verursachende und in Abhängigkeit von der genauen Zusammensetzung mehr oder weniger toxische Eigenschaften Andere Rauch- und Nebelsätze bestehen aus einer Mischung von Hexachloräthan mit Metallpulver, wie Zink, Aluminium, Titan, Magnesium und Eisen.A disadvantage of these known mist sets are their cough-causing properties and, depending on the exact composition, more or less toxic properties. Other smoke and mist sets consist of a mixture of hexachloroethane with metal powder, such as zinc, aluminum, titanium, magnesium and iron.

Diese Mischungen weisen den Nachteil auf, daß das Hexachloräthan sehr hydrolyseempfindlich ist und leicht bereits im Herstellungsprozeß mit Wasserdampf oder Feuchtigkeit reagiert. Darüber hinaus sind derartige Mischungen wenig lagerstabil und neigen zu Brennzeitänderungen.These mixtures have the disadvantage that the hexachloroethane is very sensitive to hydrolysis and easily reacts with water vapor or moisture already in the manufacturing process. In addition, such mixtures are not very stable in storage and tend to change the burning time.

Übliche Anzündsätze für Brand- oder Nebelsätze weisen als Hauptbestandteile Magnesiumpulver, Schwarzpulvermehl und ein Bindemittel auf. Sie besitzen den Nachteil, daß sie nicht unter eindeutig zu definierenden Bedingungen zünden und darüber hinaus nur gering mechanisch belastbar sind.Usual igniter sets for fire or smoke sets contain magnesium powder, black powder flour and a binding agent as main components. They have the disadvantage that they do not ignite under clearly defined conditions and, moreover, are only mechanically resilient.

Ein weiterer Nebelsatz ist aus der DE-OS 27 43 363 bekannt. Als Bestandteile weist er Zinkoxid, Ammoniumperchlorat, Polychlorisopren sowie einen Weichmacher und zur Abpufferung Ammoniumchlorid auf. Auch dieser Nebelsatz weist den Nachteil auf, daß beim Abbrennen cancerogene Verbrennungsprodukte entstehen. Ferner ist das Verfahren zu seiner Herstellung sehr aufwendig, da er vergossen und mit zwei Überzügen zur Stabilisierung und zum Schutz gegen äußere Einflüsse versehen werden muß.Another set of fog is known from DE-OS 27 43 363. It contains zinc oxide, ammonium perchlorate, polychloroisoprene as well as a plasticizer and ammonium chloride for buffering. This mist set also has the disadvantage that carcinogenic combustion products are formed when it burns. Furthermore, the process for its production is very complex, since it has to be cast and provided with two coatings for stabilization and protection against external influences.

Aufgabe der Erfindung ist es, eine pyrotechnische Ladung als Nebel- oder als Brandsatz in Form von in einer Hülle angeordneten einzelnen Preßkörpern anzugeben, die einfach und billig herstellbar ist und eine bessere Verteilung der gezündeten Nebel- oder Brandsätze ermöglicht.The object of the invention is to provide a pyrotechnic charge as a smoke or as a fire in the form of individual moldings arranged in a casing, which is simple and inexpensive to manufacture and enables a better distribution of the ignited smoke or incendiary charges.

Eine weitere Aufgabe der Erfindung ist es, eine gegenüber dem Stand der Technik verbesserte neue Mischung eines Nebel-, Brand- und Zündsatzes sowie Verfahren zu deren Herstellung bereitzustellen.Another object of the invention is to provide a new mixture of a fog, fire and primer, and methods for their production, which is improved over the prior art.

Die Aufgabe wird durch eine pyrotechnische Ladung als Nebel- oder als Brandsatz in Form von in einer Hülle angeordneten einzelnen Preßkörpern, dadurch gelöst, daß die Hülle für die Preßkörper aus mit Sollbruchstellen versehenem Kunststoff oder Leichtmetall besteht.The object is achieved by a pyrotechnic charge as a fog or as a fire in the form of individual compacts arranged in a casing, in that the casing for the pressed body consists of plastic or light metal provided with predetermined breaking points.

Eine derartige Hülle verbirst leicht nach der Zündung und sichert daher eine bessere Raumverteilung der Nebel- bzw. Brandsätze, außerdem verbleiben nur kleine Hüllenteile, so daß eine Verletzungsgefahr dadurch nicht gegeben ist.Such a cover easily hides after ignition and therefore ensures a better distribution of the fog or incendiary charges, in addition, only small parts of the cover remain, so that there is no risk of injury.

Vorzugsweise sind die Preßkörper mit Aussparungen versehen und schichtförmig übereinander angeordnet. Durch diese Ausgestaltung der Preßkörper wird deren bessere Zerlegung gesichert und damit auch eine bessere Raumverteilung erreicht.The pressing bodies are preferably provided with cutouts and arranged one above the other in the form of a layer. This configuration of the pressed body ensures that it is better disassembled and thus also better space distribution is achieved.

Es ist vorteilhaft, daß die Aussparungen aller Preßkörper einen durchgehenden Kanal bilden, in dem zerlegend wirkende Anzündsätze raumfüllend angeordnet sind. Hierdurch erübrigt sich ein zusätzliches Zündrohr und es wird die Reibung zwischen den einzelnen Preßkörpern ausgeschlossen.It is advantageous that the recesses of all the pressing bodies form a continuous channel in which igniting charges are arranged to fill the space. This eliminates the need for an additional ignition tube and prevents friction between the individual compacts.

Bevorzugte pyrotechnische Ladungen als Nebelsatz sind den Ansprüchen 4 bis 7, ein Verfahren zu deren Herstellung dem Anspruch 8 zu entnehmen.Preferred pyrotechnic charges as a mist set are claims 4 to 7, a process for their preparation from claim 8.

Im Anspruch 9 ist eine bevorzugte pyrotechnische Ladung als Brandsatz und in Anspruch 10 ein vorteilhaftes Verfahren zu deren Herstellung angegeben.In claim 9, a preferred pyrotechnic charge is set as a fire and in claim 10, an advantageous method for its production.

Die Ansprüche 11 bis 16 geben vorzugsweise für die erfindungsgemäßen pyrotechnischen Ladungen zu verwendende Anzündsätze wieder, Anspruch 17 gibt ein vorteilhaftes Verfahren zu deren Herstellung wieder.Claims 11 to 16 preferably represent ignition charges to be used for the pyrotechnic charges according to the invention, claim 17 represents an advantageous method for their production.

Nachstehend wird die Erfindung anhand von Ausführungsbeispielen unter Bezug auf Zeichnungen näher erläutert. Es zeigt:

  • Fig. 1 eine pyrotechnische Ladung aus Preßkörpern mit Anzündsatz in einer Hülle,
  • Fig. 2a einen Preßkörper in perspektivischer Darstellung,
  • Fig. 2b-d die Zerlegung eines Preßkörpers nach dem Zünden des Zündsatzes in Draufsicht.
The invention is explained in more detail below using exemplary embodiments with reference to drawings. It shows:
  • 1 is a pyrotechnic charge from pressed bodies with an ignition charge in a shell,
  • 2a shows a pressing body in a perspective view,
  • Fig. 2b-d the disassembly of a compact after igniting the primer in plan view.

Eine pyrotechnische Ladung als Nebel- oder Brandsatz ist in einer vorzugsweise zylindrischen Hülle 1 angeördnet. Die Hülle 1 (Fig. 1) ist mit Längs- und/oder Quersollbruchstellen 2 versehen. Diese können als an der Innenseite der Hülle 1 ausgeführte Kerben oder Bruchlinien oder in Form von Materialverdünnungen hergestellt sein. Die Hülle 1 besteht aus einem Kunststoff, kann aber auch aus einem Leichtmetall, wie z.B. Aluminium oder aus Leichtmetall-Legierungen bestehen.A pyrotechnic charge as a smoke or fire charge is arranged in a preferably cylindrical shell 1. The envelope 1 (FIG. 1) is provided with longitudinal and / or transverse breaking points 2. These can be produced as notches or fracture lines on the inside of the casing 1 or in the form of material dilutions. The sleeve 1 is made of a plastic, but can also be made of a light metal, such as Made of aluminum or light metal alloys.

In der Hülle 1 sind die Nebel- oder Brandsatzmischungen als scheibenförmige Preßkörper 3 aufeinandergestapelt angeordnet. Der Außendurchmesser und die Gestalt der scheibenförmigen Preßkörper entspricht dem Innendurchmesser und der Gestalt der Hülle 1. Die Preßkörper 3 weisen Aussparungen 4 auf, die vorzugsweise achssymmetrisch angeordnet und den zentralen Bereich einschließen. In Fig. 1 und 2 sind kreuzförmige Aussparungen 4 dargestellt, sie können aber auch sternförmig mit beliebiger Zackenzahl oder auch blattförmig gerundet oder als einfacher rechteckiger Schlitz ausgeführt sein.In the casing 1, the mist or incendiary mixtures are stacked on top of one another as disk-shaped pressing bodies 3. The outside diameter and the shape of the disk-shaped pressing bodies correspond to the inside diameter and the shape of the casing 1. The pressing bodies 3 have recesses 4, which are preferably arranged axially symmetrically and enclose the central area. 1 and 2 cross-shaped recesses 4 are shown, but they can also be star-shaped with any number of points or rounded in a leaf shape or as a simple rectangular slot.

Die zum Außenrand weisenden Teile der Aussparungen 4 bilden gleichzeitig Sollbruchstellen 5 beim Zerlegen der Preßkörper 3 werden derart mittels eines entfernbaren Zentrierstabes, der die Form der Aussparungen 4 wiedergibt, übereinander geschichtet, daß die Aussparungen 4 einen durchgehenden Kanal 6 bilden. In den Kanal 6 werden anschließend raumfüllende Anzündsatzpreßkörper 7 eingeführt. Durch die Gestalt der Preßkörper 4 wird die Hülle 1 lückenlos gefüllt, wobei ein zentrales Innenzündrohr überflüssig wird. Der gebildete Kanal-6 wird ebenfalls lückenlos mittels der Anzündsatzpreßkörper 7 gefüllt, so daß ein vorzeitiges Verkrümeln der Ladung beim Transport ausgeschlossen ist und ein unmittelbarer Kontakt zwischen Anzündsatz und Nebel- bzw. Brandsatz gegeben ist. Die scheibenförmigen Preßkörper sind leicht herzustellen und ebenso leicht in die Hülle einzubringen.The parts of the recesses 4 facing the outer edge simultaneously form predetermined breaking points 5 when disassembled the pressing body 3 are layered one above the other by means of a removable centering rod, which shows the shape of the recesses 4, in such a way that the recesses 4 form a continuous channel 6. Subsequently, space-filling ignition molded bodies 7 are introduced into the channel 6. Due to the shape of the pressing body 4, the shell 1 is filled without gaps, a central internal ignition tube being superfluous. The channel 6 formed is also filled completely by means of the ignition charge compression body 7, so that premature crumbling of the load during transport is excluded and there is direct contact between the ignition charge and fog or fire charge. The disk-shaped pressing bodies are easy to manufacture and just as easy to insert into the casing.

Im Zeitpunkt der Zündung der Ladung brennen die Anzündsatzpreßkörper 7 durch, entzünden die Preßkörper 3 des Nebel- bzw. Brandsatzes, die an den durch die Aussparungen 4 vorgegebenen Sollbruchstellen 5 zerbersten, worauf aufgrund des stärker werdenden Innendruckes die Hülle 1 an den dort angeordneten Sollbruchstellen 2 zerbirst. Dadurch werden die Einzelteile der Preßkörper 3 des Nebel- bzw. Brandsatzes weiter zerlegt und in alle Richtungen verteilt. Die drei Komponenten Anzündsatz, Nebel- bzw. Brandsatz und Hülle wirken also auch insofern optimal zusammen, als Anzündung und Druckaufbau zum selben Zeitpunkt eintreten. Je nach vorgegebener und variabler Zerlegungsenergie verteilen sich die Einzelteile über ein definierbares Feld, wobei z.B. ein homogener Nebel erzeugt wird.At the time of ignition of the charge, the ignition charge compression bodies 7 burn, ignite the compression bodies 3 of the fog or incendiary charge, which burst at the predetermined breaking points 5 given by the recesses 4, whereupon the casing 1 at the predetermined breaking points 2 arranged there due to the increasing internal pressure bursts. As a result, the individual parts of the press body 3 of the mist or incendiary device are further broken down and distributed in all directions. The three components of primer, mist or incendiary and casing therefore work together optimally in that the ignition and pressure build up occur at the same time. Depending on the specified and variable disassembly energy, the individual parts are distributed over a definable field, e.g. a homogeneous fog is created.

Der Nebel bzw. die Brandsegmente werden schnell und gleichzeitig dauerhaft erzeugt. Die Nebel- bzw. Brandzeit läßt sich durch unterschiedliche Dicke der Preßkörper als auch insbesondere durch Variation ihrer Zusammensetzung, wobei unterschiedliche Abbrandzeiten erreicht werden, steuern.The fog or the fire segments are quickly and permanently generated. The fog or fire time can be determined by varying the thickness of the pressed body and, in particular, by varying its composition, with different burn-off times being achieved will control.

Die Nachteile bekannter Nebelmischungen, wie saure Reaktion der Nebelpartikel, Lagerinstabilität und Neigung zu Brennzeitänderungen, werden durch einen Nebelsatz vermieden, der folgende Zusammensetzung in Gew.% aufweist:

Erfindungsgemäß werden die Nebelmischungen in Form von Preßkörpern dadurch hergestellt, daß die Komponenten mit einem lösungsmittelhaltigen Bindemittel miteinander vermischt, getrocknet, mit einem Reibschnitzler zerkleinert und nachfolgend unter Anwendung eines Druckes von 500 bis 1500 bar zu Preßkörpern verpreßt werden. Durch dieses Verfahren werden besonders stabile Preßkörper erzeugt, die eine hohe mechanische Belastbarkeit aufweisen und nicht in kleine Teile zerplatzen. Die hohe mechanische Stabilität der Preßkörper ist auf mehrere Faktoren zurückzuführen. Sie ergibt sich aus dem Gemisch der einzelnen Komponenten, aus der völlig unregelmäßigen Schnitzelform der Teilchen und ihrem Verpressen unter Druck. Die Körper sind in verschiedenen Größen bis zu mindestens 155-er Kaliber herzustellen. Durch die Variation der Stärke der Preßkörper kann die Brennzeit gesteuert werden.According to the invention, the mist mixtures are produced in the form of compacts in that the components are mixed with one another with a solvent-containing binder, dried, comminuted with a friction shredder and subsequently pressed to form compacts using a pressure of 500 to 1500 bar. This process produces particularly stable compacts, which have a high mechanical strength and do not burst into small parts. The high mechanical stability of the pressed body can be attributed to several factors. It results from the mixture of the individual components, from the completely irregular shape of the particles and their compression under pressure. The bodies can be made in different sizes up to at least 155 caliber. The firing time can be controlled by varying the thickness of the pressed body.

Nachstehend wird ein konkretes Ausführungsbeispiel der Herstellung von Preßkörpern eines Nebelsatzes angeführt.Below is a specific embodiment of the manufacture of moldings of a fog set.

Ein Ansatz von 2,2 kg PVC-Pulver, 3,3 kg Zinkoxid (getrocknet), 2,2 kg Ammoniumchlorid und 2,64 kg Thioharnstoff wird durch ein Sieb mit einer Maschenweite von 0,3 bis 0,55 mm gedrückt und anschließend intensiv vermischt. Sodann wird der Ansatz in eine Knetmaschine eingebracht und mit 2,4 kg (bezogen auf den festen Anteil, d.h. ohne Lösungsmittelanteil) eines hochviskosen Elastomerbinders 15 Minuten angeteigt. Nach Beendigung des Knetvorgangs wird nach demselben Siebverfahren bearbeitetes Ammoniumperchlorat in einer Menge von 7,26 kg zugegeben. Dieser Ansatz wird weitere 15 Minuten geknetet, sodann auf Horden ausgebreitet und nachfolgend 6 Stunden bei einer Temperatur von 45°C getrocknet.A batch of 2.2 kg of PVC powder, 3.3 kg of zinc oxide (dried), 2.2 kg of ammonium chloride and 2.64 kg of thiourea is pressed through a sieve with a mesh size of 0.3 to 0.55 mm and then intensely mixed. The batch is then introduced into a kneading machine and pasted for 15 minutes with 2.4 kg (based on the solid portion, i.e. without solvent portion) of a highly viscous elastomer binder. After the kneading process is completed, ammonium perchlorate processed in the same sieving process is added in an amount of 7.26 kg. This mixture is kneaded for a further 15 minutes, then spread out on trays and subsequently dried at a temperature of 45 ° C. for 6 hours.

Anschließend wird die erhaltene Trockenmasse in einer Reibschnitzelmaschine zerkleinert und schließlich unter einem Druck von etwa 1000 bar zu Preßkörpern verpreßt.The dry matter obtained is then comminuted in a grating machine and finally under a pressure of about 1000 bar pressed into compacts.
