Description

Verfahren zur Herstellung unentmischbarer preßfähiger Sprengstoffgemische In den meisten Fällen werden die wertvollen und hochbrisanten Sprengstoffe, wie Trimethylentrinitramin oder Pentaerythrittetranitrat, nicht für sich allein zu Sprengladungen verarbeitet, sondern aus Gründen der Wirtschaftlichkeit und der Handhabungssicherheit mit wohlfeileren und weniger empfindlichen Sprengstoffen, wie z. B. Trinitrotoluol, vermischt. Es hat sich gezeigt, daß sich vollkommen homogene Mischungen nur schwer herstellen lassen und daß auch bei sehr inniger Vermischung wegen der verschiedenen mechanischen Eigenschaften der Komponenten (spezifisches Gewicht, Kristallform, Kristallgröße) nachträglich leicht Entmischungen eintreten können. Hierdurch werden nicht nur die sprengtechnischen Eigenschaften der erhaltenen Sprengladungen in unerwünschter Weise verändert, sondern es werden auch durch Anreicherung des hochbrisanten Sprengstoffes in bestimmten Anteilen der Mischungen Gefahren beim Pressen der Sprengladungen verursacht.Process for the production of immiscible, compressible explosives mixtures In most cases, the valuable and highly explosive explosives such as Trimethylene trinitramine or pentaerythritol tetranitrate, not by itself to form explosive charges processed, but for reasons of economy and handling safety cheaper and less sensitive explosives such as B. trinitrotoluene, mixed. It has been shown that completely homogeneous mixtures are difficult to achieve can be produced and that even with very intimate mixing because of the different mechanical properties of the components (specific weight, crystal shape, Crystal size) afterwards segregation can easily occur. This will be not only the properties of the explosive charges obtained are undesirable Wise changed, but it will also be done by enriching the highly explosive explosives in certain proportions of the mixtures causes hazards when pressing the explosive charges.

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Sprengstoffmischungen, die sich nachträglich nicht mehr entmischen können. Dies wird erfindungsgemäß dadurch erreicht, daß man einen hochschmelzenden Sprengstoff mit einer Schicht eines niedrigschmelzenden Sprengstoffes unter Verwendung an sich allgemein bekannter Verfahren überzieht und dabei so vorgeht, daß man den nicht oder bei hoher Temperatur schmelzbaren Sprengstoff mit dem tiefer schmelzenden Sprengstoff bei einer Temperatur vermischt, die zwischen den Schmelzpunkten der beiden Komponenten liegt. Zweckmäßig kühlt man noch während des Mischens ab, bis der geschmolzene Sprengstoff erstarrt ist.The invention relates to a process for the production of explosives mixtures, which can no longer separate afterwards. According to the invention, this is thereby achieved achieved that a high-melting explosive with a layer of a low-melting Coating and explosive using per se generally known methods proceed in such a way that the explosive, which cannot be melted or melted at high temperature, is used mixed with the lower melting explosive at a temperature which is between the melting points of the two components. It is advisable to cool down during mixing until the molten explosive has solidified.

Als schmelzbare Sprengstoffe kommen beispielsweise verschiedene Nitroderivate des Toluols, Benzols, Naphthalins, Phenylglykoläthers in Betracht. Wählt man als niedrigschmelzende Sprengstoffkomponente einen wenig empfindlichen Sprengstoff, wie z. B. Bi- oder Trinitrotoluol, so wird damit gleichzeitig eine ausgezeichnete Phlegmatisierung des hochbrisanten Sprengstoffes von höherem Schmelzpunkt, wie z. B. Pentaerythrittetranitrit, Trimethylentrinitramin od. dgl. erreicht. Diese Art der Phlegmatisierung hochbrisanter Sprengstoffe besitzt gegenüber der bekannten mit wachsartigen Substanzen den Vorteil, daß die Leistungsfähigkeit des Sprengstoffes in weit geringerem Maße durch das Phlegmatisierungsmittel beeinträchtigt wird.Various nitro derivatives, for example, can be used as fusible explosives of toluene, benzene, naphthalene, phenyl glycol ethers into consideration. Choose as low-melting explosive component a less sensitive explosive, such as B. Bi- or trinitrotoluene, it is an excellent one at the same time Phlegmatization of highly explosive explosives with a higher melting point, such as B. Pentaerythritol tetranitrite, trimethylene trinitramine or the like. Achieved. This kind the phlegmatization of highly explosive explosives has compared to the known with waxy substances the advantage that the performance of the explosive is affected to a much lesser extent by the phlegmatizer.

Eine erfindungsgemäß hergestellte Mischung von Trimethylentrinitramin mit 10% Binitrotoluol vom Erstarrungspnukt 35° C ergab eine 2-kg-Fallhammer-Empfindlichkeit von 70 cm, gegenüber nur 15 cm bei dem reinen Sprengstoff. Der Wert für die Bleiblockausbauchung war nur um 20 cm3 vermindert.A mixture of trimethylene trinitramine made in accordance with the invention with 10% binitrotoluene with a solidification point of 35 ° C resulted in a 2 kg drop hammer sensitivity of 70 cm, compared to only 15 cm for pure explosives. The value for the lead block bulge was only reduced by 20 cm3.

Für eine in gleicher Weise mit 10% Trinitro.toluol hergestellte Mischung wurde eine 2-kg-Fallhammer-Empfindlichkeit von noch 50 cm ermittelt.. Der Unterschied der Bleiblockausbauchung gegenüber dem reinen Trimethylentrinitramin betrug nur 18 cm3.For a mixture made in the same way with 10% trinitro.toluene a 2 kg drop hammer sensitivity of 50 cm was determined. The difference the lead block bulge compared to the pure trimethylene trinitramine was only 18 cm3.

Es ist zwar bereits bekannt, im Zuge der Herstellung von Preßkörpern Mischungen aus einem höherschmelzenden Sprengstoff und einem niedrigerschmelzenden Hilfssprengstoff herzustellen und die Mischung auf eine Temperatur in der Nähe des Schmelzpunktes des Hilfssprengstoffes zu erwärmen und bei dieser Temperatur zu verpressen. Der Anmeldungsgegenstand löst dagegen die Aufgabe, zwei Sprengstoffe, die eine pre:Bbare Mischung ergeben, in eine unentmischbare Form zu bringen, und das Verpressen des erhaltenen Gemisches muß keineswegs unmittelbar anschließend an seine Herstellung erfolgen.It is already known in the course of the production of pressed bodies Mixtures of a higher melting explosive and a lower melting one Prepare auxiliary explosives and bring the mixture to a temperature near the To heat the melting point of the auxiliary explosive and to press it at this temperature. The subject of the application, however, solves the problem of two explosives, one pre: Bbare Result in the mixture, to bring it into an immiscible form, and the pressing of the The mixture obtained must by no means immediately follow its production take place.
