Definitions

  • the invention relates to a cast explosive charge with trinitrotoluene (TNT) as a fusible component, with at least one further energy source as a solid filler and with a finely ground inert solid which is present in an amount of 0.01 to 5% by weight.
  • TNT trinitrotoluene
  • Suitable solid fillers are in particular nitramines, nitric acid esters and metal powders such as aluminum powder.
  • a cast explosive charge made of TNT is known from DE-OS 23 00 655, which contains a plasticizer in order to reduce the excretion.
  • a further energy source in the form of a solid filler and a conventional desensitizing agent can be added to the known explosive charge.
  • Finely divided inert solids are also suitable as phlegamizing agents, for example finely divided calcium phosphate with a specific surface area of 1 m2 / g.
  • the sedimentation of the solid fillers is a major problem when casting TNT explosive charges. This not only affects the blast effect, but also the mechanical properties are adversely affected, because in general the zone in which the solid filler, e.g. . B. the aluminum powder, enriched, brittle. Likewise, the sedimentation of the solid fillers increases the sensitivity to explosive charges. Above all, however, the reproducibility of the properties of the explosive charge suffers from such sedimentation or segregation.
  • the invention as characterized in the claims, is based on the task of creating, using the simplest means, a cast explosive charge which has practically no segregation of the components.
  • Carbon black is particularly suitable as a substance with a large specific surface area in the explosive charge according to the invention, since there are many different, defined types of carbon black on the market and thus an excellent optimization of the soot in relation to the respective explosive charge is possible.
  • the carbon black content is preferably 0.01 to 0.1% by weight.
  • aerosil, aluminum silicates, rutile and the like can also be used as substances with a large specific surface area in the explosive charge according to the invention.
  • An example of the preparation of an explosive charge according to the invention is given below: 40 g of TNT are melted, kept at a temperature of 95 ° C. and mixed with 60 g of hexogen with stirring. 400 mg of acetylene black are then added to the mixture, which is kept at a temperature of 95 ° C., with stirring. The mixture is then placed in a mold and allowed to cool slowly to room temperature.
  • the accompanying drawing serves to further explain the invention. It represents a diagram which shows the separation of an explosive charge as a function of the amount of soot added.
  • the explosive charge which was produced in accordance with the exemplary embodiment specified above, consists of 40% by weight of TNT and 60% by weight of hexogen; however, it contains different amounts of soot, namely 0.0, 0.1; 0.2 ; 0.3; 0.4 and 0.5 wt%.
  • soot proportions are shown on the abscissa of the diagram.
  • the test tube is about half full.
  • the cast explosive body was removed from the test tube and, as shown schematically in the diagram, divided into five zones of the same height (about 1 to 2 cm).
  • the zones were from the bottom, i. H. numbered “1" to "5" from the bottom of the test tube upwards.
  • the lowest zone, i.e. zone 1 and the fourth zone from below, i.e. zone 4 were each analyzed for their hexogen content.
  • the hexogen content of the zones was determined by eluting the TNT with toluene, after which the hexogen was filtered off and weighed.
  • zone 1 contains eight% by weight more hexogen than zone 4, while with the addition of only 0.2% by weight of carbon black, the hexogen separation is only 2% by weight and at a soot content of 0.4 to 0.5% to a negligibly low value of about 0.5 Cew .-%.
