Definitions
- the invention relates to a plastic-bound cast explosive. Similar explosives have been known in the area of ammunition for weapon systems for some time, since modern weapon systems place ever increasing demands on the explosives used.
- Pressable explosives in which the components of the granulate are coated with a plastic binder have been known for a long time.
- the pourable explosives which usually contain a not inconsiderable amount of inert binder, are less sensitive than the compressed explosives, which ultimately reduces the performance values.
- DE 43 24 739 discloses an explosive which is castable in the processing state and which contains an ester of a monocarboxylic acid as plasticizer.
- plastics are used as binders, for example polyurethane, polyacrylate or polyacrylonitrile resins.
- Such pourable explosives also have disadvantages. Of particular note are the limited processing time and the toxic hardener, which requires special protective measures during processing.
- an explosive has become known from DE 40 06 961 A1, which consists of an explosive embedded in plastic as compressible granules.
- the proportion of explosives here is over 90% by weight, preferably 95 to 98%.
- the proportion of the binder is less than 10% by weight, preferably in the range from 5 to 2% by weight. Any plasticizer can be used, with no emphasis being placed on improving the properties of the explosive by using a special plasticizer.
- the explosives produced in the proposed manner have a number of advantages.
- special protective measures during processing can be dispensed with.
- Silicone binder is not a dangerous good.
- the hardener used here is not harmful to health. This means that the usual breathing protection during processing can be dispensed with.
- the binder components are mixed at room temperature, thus saving time and energy.
- the pourable explosive / binder / plasticizer mixture is also poured at room temperature. Since the mixture reacts very slowly at this temperature, pot times or storage times of several days to a few weeks can be used.
- Curing is only accelerated by heating up to 120 ° C. The final hardness is then reached relatively quickly. Instead of curing times of more than one day for polyurethane resins, curing times of significantly less than one day now occur. Since the processing effort can be reduced to almost half of the usual values to date, the use of the proposed explosives instead of the previous explosives also has a not inconsiderable economic advantage.
- the self-ignition temperature found in tests is about 30 - 40 ° C higher than with the usual explosives bound with polyurethane. This means there is less risk of high ambient temperatures.
- silicone binders allows the use of a certain degree of freedom in the choice of the mixing ratio. Since the aging resistance of silicones is better than that of polyurethanes, less measures are required to counteract the effects of aging or weathering.
- silicone oil Due to the addition of silicone oil to the binder, the following advantageous mechanical properties are achieved.
- the degree of hardness of the cast and hardened explosives can be set within a wide range.
- a hardness of over 70 (Shore A) is achieved with a proportion of approximately 30% by weight of the plasticizer, with a plasticizer proportion of approximately 50% by weight in the binder, the hardness of the finished explosive is reduced to values of around 50 (Shore A).
- the desired viscosity of the casting compound could also be set in a similar manner. With a plasticizer content of 50 to 30% by weight, the viscosity of the pourable mass of about 1000 to 3000 (Pas).
- silicone-based binders also gives the user the desired advantage of a higher autoignition temperature, which is now around 30-40 ° C higher than that of an explosive with a conventional HTPB binder, namely just below 260 ° C.
- a silicone resin for example Elastosil from Wacker
- a crosslinker for example type W from Wacker
- a silicone oil for example AK from Wacker
- a catalyst for example type OL from Wacker
- the casting bodies are cured at a temperature of above 80 ° C., preferably in the range from 100 to 120 ° C. over a period of less than 12 hours, depending on the caliber of the casting.
- silicone resin also enables the use of silicone oil or a mixture of silicone oils as plasticizers.
- the silicone oils are mixtures of different lengths and differently substituted, linear or cyclic siloxane chains. Structurally, silicone oils and silicone resin are closely related. This results in a very good compatibility of resin and plasticizer. Silicone oils are clear, colorless, neutral and hydrophobic liquids with a viscosity that can be set within a wide range (10 to 1,000,000 (cSt.)).
- silicone oils are diverse. They range from being used as a release agent in the glass, rubber and paper industries or as Defoamer or glass coating in the beverage industry to use in medicine and pharmacy. However, the use as an auxiliary in the production of cast explosives is not described in the relevant literature (for example: Römpp Chemie Lexikon).
- the cast explosive according to the invention has, due to the use of silicone resin as a binder, some properties which are improved over known explosives. In addition to the pourability at room temperature, which makes processing easier, the thermal resistance has been significantly improved. Experiments have shown an increase in the autoignition temperature by 30 to 40 ° C compared to pourable explosives with HTPB binder.

Abstract
Description
Die Erfindung betrifft einen kunststoffgebundenen gegossenen Sprengstoff. Ähnliche Sprengstoffe sind im Bereich der Munitionen für Waffensysteme seit einiger Zeit bekannt, da die modernen Waffensysteme ständig wachsende Anforderungen an die verwendeten Sprengstoffe stellen.The invention relates to a plastic-bound cast explosive. Similar explosives have been known in the area of ammunition for weapon systems for some time, since modern weapon systems place ever increasing demands on the explosives used.
Neben der hohen Leistung, die zur Anwendung bei harten technischen Zielen notwendig ist, wird auch eine geringe Empfindlichkeit angestrebt, da hierdurch eine geringere Wahrscheinlichkeit der ungewollten Auslösung im Fall von Beschuss oder Brand zu erwarten ist.In addition to the high performance required for use in tough technical targets, low sensitivity is also sought, since this is to be expected to reduce the likelihood of unintentional triggering in the event of fire or fire.
Seit langem bekannt sind pressbare Sprengstoffe, bei denen die Bestandteile des Granulats mit einem Kunststoffbinder ummantelt sind. Weniger empfindlich als die gepressten Sprengstoffe sind die gießbaren Sprengstoffe, die gewöhnlich einen nicht unerheblichen Anteil inerten Binders enthalten, wodurch letztlich die Leistungswerte sinken. Aus der DE 43 24 739 ist beispielsweise ein im Verarbeitungszustand gießbarer Sprengstoff bekannt geworden, der als Weichmacher ein Ester einer Monocarbonsäure enthält. Als Binder werden in der Regel Kunststoffe verwendet, wie beispielsweise Polyurethan-, Polyacrylat-, oder Polyacrylnitril-Harze. Derartige gießfähige Sprengstoffe weisen aber auch Nachteile auf. Hervorzuheben sind hierbei die begrenzte Verarbeitungszeit und der giftige Härter, der besondere Schutzmaßnahmen bei der Verarbeitung erforderlich macht.Pressable explosives in which the components of the granulate are coated with a plastic binder have been known for a long time. The pourable explosives, which usually contain a not inconsiderable amount of inert binder, are less sensitive than the compressed explosives, which ultimately reduces the performance values. DE 43 24 739, for example, discloses an explosive which is castable in the processing state and which contains an ester of a monocarboxylic acid as plasticizer. As a rule, plastics are used as binders, for example polyurethane, polyacrylate or polyacrylonitrile resins. Such pourable explosives also have disadvantages. Of particular note are the limited processing time and the toxic hardener, which requires special protective measures during processing.
Ein weiterer Lösungsansatz ist in der EP 0 316 991 A2 beschrieben. Demnach werden 55 bis 90 Gew.-% eines teilchenförmigen Hochleistungssprengstoffes mit 10 bis 45 Gew.-% eines zu fester Form aushärtbaren fließfähigen Bindemittels gemischt. Letzteres zeichnet sich durch einen besonders hohen Fluorgehalt aus. Es entfällt hierbei jedoch die Einflussmöglichkeit auf die Viskosität des gießfähigen Sprengstoff-Binder-Gemisches und auf die mechanischen Eigenschaften des ausgehärteten Produkts.Another approach is described in EP 0 316 991 A2. Accordingly, 55 to 90% by weight of a particulate high-performance explosive is mixed with 10 to 45% by weight of a flowable binder that can be hardened into a solid form. The latter is characterized by a particularly high fluorine content. However, there is no possibility of influencing the viscosity of the pourable Explosives-binder mixture and on the mechanical properties of the cured product.
Schließlich ist aus der DE 40 06 961 A1 ein Sprengstoff bekannt geworden, der als verpressbares Granulat aus in Kunststoff eingebettetem Sprengstoff besteht. Der Sprengstoffanteilbeträgt hierbei über 90 Gew.%, vorzugsweise 95 bis 98%. Der Anteil des Bindemittels ligt unter 10 Gew.%, vorzugsweise im Bereich von 5 bis 2 Gew.%. Es können beliebige Weichmacher eingesetzt werden, wobei kein Wert auf die Verbesserung von Eigenschaften des Spengstoffes durch Verwendung eines besonderen Weichmachers gelegt wird.Finally, an explosive has become known from DE 40 06 961 A1, which consists of an explosive embedded in plastic as compressible granules. The proportion of explosives here is over 90% by weight, preferably 95 to 98%. The proportion of the binder is less than 10% by weight, preferably in the range from 5 to 2% by weight. Any plasticizer can be used, with no emphasis being placed on improving the properties of the explosive by using a special plasticizer.
Es ist Aufgabe der vorliegenden Erfindung, einen im Verarbeitungszustand gießbaren Sprengstoff hoher Leistung zu entwickeln, dessen Binderbestandteile gesundheitlich unbedenklich sind, der als gießfähige Fertigmischung bei Raumtemperatur über längere Zeit verarbeitungsfähig bleibt und dessen mechanische Eigenschaften nach erfolgter Aushärtung den heute aktuellen Anforderungen genügen und der thermisch unempfindlicher als die bisher verwendeten Sprengstoffe ist.It is an object of the present invention to develop a high-performance explosive which can be cast in the processing state, the binder components of which are harmless to health, which can be processed as a pourable ready-to-use mixture at room temperature over a long period of time and whose mechanical properties after curing have met the current requirements and which are less sensitive to heat than the explosives used so far.
Die Aufgabe wird in einfacher Weise durch den in Anspruch 1 beschriebenen Sprengstoff und das in Anspruch 7 wiedergegebene Verfahren gelöst. Vorteilhafte Ausgestaltungen sind den jeweils nachgeordneten Ansprüchen zu entnehmen.The object is achieved in a simple manner by the explosive described in claim 1 and the method described in claim 7. Advantageous configurations can be found in the respective subordinate claims.
Der auf die vorgeschlagene Weise hergestellte Sprengstoff weist eine Reihe von Vorteilen auf. Bei Verwendung eines Binders auf der Basis von Silikonharz kann auf besondere Schutzmaßnahmen bei der Verarbeitung verzichtet werden. Silikonbinder stellt kein Gefahrgut dar. Der hierbei verwendete Härter ist nicht gesundheitsschädlich. Somit kann der bisher übliche Atemschutz bei der Verarbeitung entfallen. Die Mischung der Binderkomponenten erfolgt bei Raumtemperatur, somit ergeben sich hieraus Einsparungen an Zeit und Energie.The explosives produced in the proposed manner have a number of advantages. When using a binder based on silicone resin, special protective measures during processing can be dispensed with. Silicone binder is not a dangerous good. The hardener used here is not harmful to health. This means that the usual breathing protection during processing can be dispensed with. The binder components are mixed at room temperature, thus saving time and energy.
Das Gießen des fließfähigen Sprengstoff-/ Binder-/ Weichmacher-Gemisches erfolgt ebenfalls bei Raumtemperatur. Da das Gemisch bei dieser Temperatur nur sehr langsam reagiert, können Topfzeiten oder Lagerzeiten von mehreren Tagen bis einigen Wochen genutzt werden.The pourable explosive / binder / plasticizer mixture is also poured at room temperature. Since the mixture reacts very slowly at this temperature, pot times or storage times of several days to a few weeks can be used.
Die Aushärtung wird erst durch Erwärmen auf bis zu 120°C beschleunigt. Die Endhärte wird dann relativ schnell erreicht. An der Stelle von Aushärtezeiten von mehr als einem Tag bei Polyurethanharzen treten nun Aushärtezeiten von deutlich weniger als einem Tag. Da der Verarbeitungsaufwand sich auf fast die Hälfte bisher üblicher Werte senken lässt, kann bei der Verwendung des vorgeschlagenen Sprengstoffes anstelle der bisherigen Sprengstoffe auch ein nicht unerheblicher wirtschaftlicher Vorteil verbucht werden.Curing is only accelerated by heating up to 120 ° C. The final hardness is then reached relatively quickly. Instead of curing times of more than one day for polyurethane resins, curing times of significantly less than one day now occur. Since the processing effort can be reduced to almost half of the usual values to date, the use of the proposed explosives instead of the previous explosives also has a not inconsiderable economic advantage.
Die in Versuchen festgestellte Selbstentzündungstemperatur liegt etwa 30 - 40 °C höher als bei den üblichen mit Polyurethan gebundenen Sprengstoffen. Somit ist ein geringeres Risiko hinsichtlich hoher Umgebungstemperaturen gegeben.The self-ignition temperature found in tests is about 30 - 40 ° C higher than with the usual explosives bound with polyurethane. This means there is less risk of high ambient temperatures.
Schließlich erlaubt die Verwendung von Silikonbinder die Nutzung eines bestimmten Freiheitsgrades bei der Wahl des Mischungsverhältnisses. Da die Alterungsbeständigkeit von Silikonen besser ist als diejenige von Polyurethanen, sind auch geringere Maßnahmen gegen Einflüsse durch Alterung oder durch Bewitterung notwendig.Finally, the use of silicone binders allows the use of a certain degree of freedom in the choice of the mixing ratio. Since the aging resistance of silicones is better than that of polyurethanes, less measures are required to counteract the effects of aging or weathering.
Aufgrund der Beimischung von Silikonöl zum Binder werden folgende vorteilhafte mechanische Eigenschaften erzielt. Abhängig von dem Gewichts-% -Anteil des Weichmachers im Binder läßt sich der Härtegrad des gegossenen und ausgehärteten Sprengstoffes in einem weiten Bereich einstellen. So erzielt man mit einem Anteil von etwa 30 Gew.-% vom Weichmacher eine Härte von über 70 (Shore A), bei einem Weichmacheranteil von etwa 50 Gew.-% im Binder reduziert sich die Härte des fertigen Sprengstoffes auf Werte um 50 (Shore A). Im ähnlicher Weise läßte sich auch die gewünschte Viskosität der Giesmasse einstellen. Bei einem Weichmacheranteil von 50 bis 30 Gew.% ergibt sich eine Viskosität der gießfähigen Masse von etwa 1000 bis 3000 (Pas). Die Verwendung von Binder auf Silikonbasis ergibt darüber hinaus auch noch den von den Anwendern erwünschten Vorteil einer höheren Selbstentzündungstemperatur, die nun etwa 30-40°C über derjenigen eines Sprengstoffes mit konventionellem HTPB-Binder liegt, nämlich bei knapp unter 260°C.Due to the addition of silicone oil to the binder, the following advantageous mechanical properties are achieved. Depending on the percentage by weight of the plasticizer in the binder, the degree of hardness of the cast and hardened explosives can be set within a wide range. Thus, a hardness of over 70 (Shore A) is achieved with a proportion of approximately 30% by weight of the plasticizer, with a plasticizer proportion of approximately 50% by weight in the binder, the hardness of the finished explosive is reduced to values of around 50 (Shore A). The desired viscosity of the casting compound could also be set in a similar manner. With a plasticizer content of 50 to 30% by weight, the viscosity of the pourable mass of about 1000 to 3000 (Pas). The use of silicone-based binders also gives the user the desired advantage of a higher autoignition temperature, which is now around 30-40 ° C higher than that of an explosive with a conventional HTPB binder, namely just below 260 ° C.
Bei Raumtemperatur und unter einem Druck von weniger als 40 mbar werden 8,0 Gew.-% eines Silikonharzes (zum Beispiel Elastosil der Firma Wacker) mit 0,4 Gew.-% eines Vernetzers (zum Beispiel Typ W der Firma Wacker) und 6,5 Gew.-% eines Silikonöls (zum Beispiel AK der Firma Wacker) unter Zugabe von weniger als 0,1 Gew.-% eines Katalysators (zum Beispiel Typ OL der Firma Wacker) vermischt. Anschließend werden 85,0 Gew.-% Oktogen untergemischt. Das Fertigmischen dauert etwa 1 Stunde bei Raumtemperatur und einem Druck von weniger als 40 mbar. Nach dem Abfüllen der fertigen Mischung unter Rütteln in einer Vakuumgießanlage bei Raumtemperatur und einem Druck von weniger als 30 mbar erfolgt das Aushärten der Gießkörper bei einer Temperatur von über 80 °C, vorzugsweise im Bereich von 100 - 120 °C über eine Zeit von weniger als 12 Stunden, abhängig vom Kaliber des Gießkörpers.At room temperature and under a pressure of less than 40 mbar, 8.0% by weight of a silicone resin (for example Elastosil from Wacker) with 0.4% by weight of a crosslinker (for example type W from Wacker) and 6 , 5% by weight of a silicone oil (for example AK from Wacker) with the addition of less than 0.1% by weight of a catalyst (for example type OL from Wacker). 85.0% by weight of octogen are then mixed in. The final mixing takes about 1 hour at room temperature and a pressure of less than 40 mbar. After the finished mixture has been filled with shaking in a vacuum casting system at room temperature and a pressure of less than 30 mbar, the casting bodies are cured at a temperature of above 80 ° C., preferably in the range from 100 to 120 ° C. over a period of less than 12 hours, depending on the caliber of the casting.
Die Verwendung von Silikonharz ermöglicht auch den Einsatz von Silikonöl oder einem Gemisch von Silikonölen als Weichmacher. Bei den Silikonölen handelt es sich um Gemische unterschiedlich langer und unterschiedlich substituierter, linearer oder cyclischer Siloxanketten. Strukturmässig sind Silikonöle und Silikonharz eng miteinander verwandt. Daraus ergibt sich eine sehr gute Verträglichkeit von Harz und Weichmacher. Silikonöle sind klare, farblose, neutrale und hydrophobe Flüssigkeiten mit einer in weitem Bereich einstellbaren Viskosität (10 bis 1000000 (cSt.)).The use of silicone resin also enables the use of silicone oil or a mixture of silicone oils as plasticizers. The silicone oils are mixtures of different lengths and differently substituted, linear or cyclic siloxane chains. Structurally, silicone oils and silicone resin are closely related. This results in a very good compatibility of resin and plasticizer. Silicone oils are clear, colorless, neutral and hydrophobic liquids with a viscosity that can be set within a wide range (10 to 1,000,000 (cSt.)).
Die bekannten Anwendungsgebiete der Silkonöle sind vielfältig. Sie reichen von der Anwendung als Trennmittel in der Glas-, Gummi- und Papierindustrie oder als Entschäumer oder Glasvergütung in der Getränkeindustrie bis zur Anwendung in der Medizin und Pharmazie. Die Verwendung als Hilfsstoff bei der Herstellung gegossener Sprengstoffe ist in der einschlägigen Literatur (zum Beispiel: Römpp Chemie Lexikon) jedoch nicht beschrieben.The known areas of application of silicone oils are diverse. They range from being used as a release agent in the glass, rubber and paper industries or as Defoamer or glass coating in the beverage industry to use in medicine and pharmacy. However, the use as an auxiliary in the production of cast explosives is not described in the relevant literature (for example: Römpp Chemie Lexikon).
Der erfindungsgemäße gegossene Sprengstoff besitzt aufgrund der Verwendung von Silikonharz als Bindemittel einige gegenüber bekannten Sprengstoffen verbesserte Eigenschaften. Neben der Gießfähigkeit bei Raumtemperatur, die zur Erleichterung der Verarbeitungsprozesse beiträgt, konnte die thermische Beständigkeit erheblich verbessert werden. In Versuchen wurde eine Erhöhung der Selbstentzündungstemperatur um 30 bis 40 °C gegenüber gießbaren Sprengstoffen mit HTPB-Binder festgestellt.The cast explosive according to the invention has, due to the use of silicone resin as a binder, some properties which are improved over known explosives. In addition to the pourability at room temperature, which makes processing easier, the thermal resistance has been significantly improved.
