Description
Die Erfindung betrifft ein Verfahren zur Herstellung gießfähiger kunststoffgebundener Sprengladungen oder Raketentreibstoffe.The invention relates to a method for producing pourable plastic bonded explosive charges or rocket fuels.
Kunststoffgebundene Sprengladungen weisen trotz einer hohen Wirkleistung eine relativ hohe Unempfindlichkeit auf. Sie bestehen aus Reaktionspolymeren, in die vor der Aushärtung kristalline Explosivstoffe, wie Octogen, Hexogen, Pentaerythrittetranitrat etc., eingearbeitet werden. Dabei beträgt der Polymeranteil etwa 10 bis 20 Gew.-%.Plastic-bonded explosive charges have a relatively high insensitivity despite a high active power on. They consist of reaction polymers in which crystalline before hardening Explosives, such as octogen, hexogen, pentaerythritol tetranitrate, etc., are incorporated. there the polymer content is about 10 to 20 wt .-%.
Ein Problem bei der Herstellung kunststoffgebundener Sprengladungen besteht darin, daß mit steigendem Feststoffanteil, d.h. mit zunehmendem Anteil an Explosivstoff, die Viskosität der Mischung so zunehmen kann, daß ein Gießen dieser Mischung unmöglich wird. Die theoretische Grenze für ein fließfähiges Gemisch liegt bei 92 Gew.-%. Es hat sich allerdings gezeigt, daß die praktische Grenze für fließfähige Gemische bei ca. 90 Gew.-% liegt. Außerdem sind Sprengladungen mit einem derart hohen Feststoffanteil nur dann gießbar, wenn die Korngrößen der für die Sprengladung verwendeten Explosivstoffkristalle innerhalb eines vorgegebenen Durchmesserintervalles liegen, so daß ein relativ kostenintensives Aussieben von Kornfraktionen erforderlich ist.A problem in the production of plastic-bound explosive charges is that with increasing Solid content, i. with increasing content of explosive, the viscosity of the mixture can increase so that a pouring of this mixture is impossible. The theoretical Limit for a flowable mixture is 92 wt .-%. However, it has been shown that the practical limit for flowable mixtures is about 90 wt .-%. There are also explosive charges with such a high solids content only pourable when the particle sizes of the for the Explosive charge used explosive crystals within a given diameter interval lie, so that a relatively expensive screening of grain fractions is required.
Aus der DE-C-38 04 396 ist es bereits bekannt, den Feststoffanteil und damit die Leistung kunststoffgebundener Sprengladungen ohne Zunahme der Viskosität dadurch zu erhöhen, daß 0,1 bis 10 Gew.-% des Feststoffes beim Mischen mit dem aushärtbaren Kunststoffbinder als Feinstkorn mit einer mittleren Korngröße kleiner 25 µm, vorzugsweise kleiner 8 µm, zugegeben wird.From DE-C-38 04 396 it is already known, the solids content and thus the performance increase plastic-bound explosive charges without increasing the viscosity, that 0.1 to 10 wt .-% of the solid when mixed with the curable plastic binder as the finest grain with a mean grain size less than 25 microns, preferably less than 8 microns added becomes.
Die Anmelderin hat in der veröffentlichten Patentanmeldung EP-A-1211232 bereits vor geschlagen, der jeweiligen Sprengladung 0,1 bis 10 Gew.-% feinstkörniges Vanadin-, Niob-, Tantal-, Chrom-, Molybdän- oder Wolfram-Pulver oder eine Mischung aus zwei oder mehreren derartigen Pulvern zuzusetzen, wobei die Pulverkörner eine im wesentlichen sphärische Form aufweisen sollen. Bei Verwendung dieser Metallpulver, die aufgrund der sphärischen Form der Pulverkörner eine sehr kleine spezifische Oberfläche aufweisen, hat sich überraschenderweise gezeigt, daß sie wie flüssige Schmiermittel zwischen den grobkörnigeren Sprengstoffpartikeln wirken (Tribologischer Effekt), so daß sich relativ niedrige Viskositäten ergeben.The Applicant has already published in published patent application EP-A-1211232 0.1-0.0% by weight of very fine-grained vanadium, the respective explosive charge, Niobium, tantalum, chromium, molybdenum or tungsten powder or a mixture from two or more such powders, wherein the powder grains a should have substantially spherical shape. When using this metal powder, due to the spherical shape of the powder grains a very small specific Have surface, has surprisingly been found that they like liquid Lubricant between the coarse-grained explosive particles act (Tribological Effect), resulting in relatively low viscosities.
Untersuchungen der Anmelderin haben ergeben, daß beim Einbringen der Metallpulver in die kunststoffgebundenen Sprengladungen bzw. Raketentreibstoffe die Viskositätsverminderung noch nicht optimal ist. Denn an der Oberfläche der Metallpulver sind häufig polare Gruppen angelagert, die mit den Isocyanaten der kunststoffgebundenen Sprengladungen bzw. mit den Raketentreibstoffen reagieren, was dann zu einem Erhöhen der Viskosität der entsprechenden Mischung führen kann. Dieses gilt insbesondere für die an der Oberfläche durch Einwirkung von Luftfeuchtigkeit angelagerten OH-Gruppen. Aber auch andere an den Metalloberflächen angelagerte polare Gruppen (z.B. Carboxyl-Gruppen) können zu einer Erhöhung der Viskosität führen.Investigations by the applicant have shown that when introducing the metal powder in the plastic-bound explosive charges or rocket propellants, the viscosity reduction not yet optimal. Because on the surface of the metal powder are often polar groups attached to the isocyanates of the plastic-bound Explosive charges or react with the rocket fuels, which then to a Increasing the viscosity of the corresponding mixture can result. This is true in particular for those deposited on the surface by the action of atmospheric moisture OH groups. But also other attached to the metal surfaces Polar groups (e.g., carboxyl groups) can increase viscosity to lead.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung unempfindlicher gießfähiger kunststoffgebundener Sprengladungen oder Raketentreibstoffe mit einem hohen (z.B. 90 %-igen) Feststoffanteil anzugeben, mit dem eine Erhöhung der Viskosität durch an der Metalloberfläche der Metallpulver angelagerte polare Gruppen vermieden wird.The invention is based on the object, a method for producing insensitive pourable plastic bonded explosive charges or rocket propellants with a high (e.g., 90%) solids content, with an increase the viscosity by polar deposited on the metal surface of the metal powder Groups is avoided.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im wesentlichen auf dem Gedanken, vor dem Einbringen des Metallpulvers in die Sprengstoffmischung ein Absättigen der polaren Gruppen des Metallpulvers durch SiR3-Gruppen (R = organischer Rest) vorzunehmen. Dadurch können die polaren Gruppen nicht mehr mit den Isocyanaten reagieren und die spezifische Oberfläche des jeweiligen Metallpulvers verringert sich. Ebenso sinkt die Viskosität der Sprengladung. Als organische Reste kommen alle Alkyl- und Arylreste in Betracht, wobei die Alkylreste reaktiver sind.The invention is based essentially on the idea of saturating the polar groups of the metal powder with SiR 3 groups (R = organic radical) before introducing the metal powder into the explosive mixture. As a result, the polar groups can no longer react with the isocyanates and the specific surface area of the respective metal powder decreases. Likewise, the viscosity of the explosive charge decreases. Suitable organic radicals are all alkyl and aryl radicals, the alkyl radicals being more reactive.
Als besonders vorteilhaft hat es sich erwiesen, zur Absättigung der polaren Gruppen des Metallpulvers Trimethylchlorsilan (Me3SiCl) zu verwenden. Dieses reagiert sofort mit den OH-Gruppen und bildet einen Silylether (-O-SiMe3).It has proven particularly advantageous to use trimethylchlorosilane (Me 3 SiCl) to saturate the polar groups of the metal powder. This reacts immediately with the OH groups and forms a silyl ether (-O-SiMe 3 ).
Bei einem Ausführungsbeispiel wurden 100 g Wolframpulver (Korngröße zwischen 3 und 5 µm) in eine Lösung aus 900 g Pentan und 20 g Trimethylchlorsilan eingebracht und 5 Minuten gerührt. Anschließend wurde das Wolframpulver abfiltriert und im Trockenschrank getrocknet. Während die spezifische Oberfläche vor der Behandlung mit Me3SiCl 0,1978 m2/g betrug, betrug sie nach der Behandlung lediglich 0,1880 m2/g, was anschließend zu einer Verringerung der Viskosität der Sprengstoffmischung von ca. 600 - 800 Pas auf ca. 400 Pas führte.In one embodiment, 100 g of tungsten powder (particle size between 3 and 5 microns) were placed in a solution of 900 g of pentane and 20 g of trimethylchlorosilane and stirred for 5 minutes. Subsequently, the tungsten powder was filtered off and dried in a drying oven. While the specific surface before treatment with Me3SiCl was 0.1978 m 2 / g, after treatment it was only 0.1880 m 2 / g, which subsequently led to a reduction of the viscosity of the explosive mixture from approx. 600 - 800 Pas to approx 400 Pas led.
Die Herstellung der erfindungsgemäßen Sprengladungen kann beispielsweise mittels
der nachfolgenden typischen Rezepturen erfolgen:
Dabei sollte die Körngröße des jeweiligen Metallpulvers zwischen 0,1 und 5 µm liegen.The grain size of the respective metal powder should be between 0.1 and 5 μm lie.
