Definitions

  • the invention relates to a method for producing an explosive which contains no carcinogenic substances and has improved handling safety (higher impact energy) than a gelatinous explosive mixture with a weight fraction of ammonium and / or sodium nitrate of the order of 40-70% Nitroglycol and / or nitroglycerin in the order of 20 to 40%, in nitrocellulose in the order of 0.5 to 3%, in a desensitizing agent and in admixtures of fillers to influence the consistency, a gelatinous explosive mixture being formed when the components are mixed, and an explosive made by this process.
  • gelatinous explosives are known for example from EP 0 012 827 B1; they contain nitroglycerin and or nitroglycol, nitrocellulose, dinitrotoluene-isomer mixtures and other active ingredient and filler admixtures; they are characterized by good blasting parameters, good initiation ability and tolerable storage stability.
  • a weather explosive which has a high NaCl content, a nitroglycerin and / or nitroglycol content of above 20% and a dinitrotoluene content of 2% with a view to avoiding undesirable ignitions.
  • the gelatinous explosives known from EP 0 012 827 B1 and DE 33 460 11 A1 contain dinitrotoluen (DNT) as a component.
  • DNT dinitrotoluen
  • the impact energy of gelatinous ammonium nitrate explosives with TNT required to trigger the explosion lies for example between 4 and 6 joules, whereby according to the valid German and European transport regulations only an explosive substance can be transported, the impact energy of which is greater than 2 J. This limit condition can be met with the known explosives.
  • the impact energy of explosives that contain TNT is close to the minimum limit. In this context, it was considered progressive to use DNT (dinitrotoluene) instead of TNT (trinitrotoluene). With it, the impact energy is significantly higher, in the order of 10 to 25 J. For health reasons, however, the use of DNT must now be avoided.
  • the object with a gelatinous explosive without carcinogenic phlegmatizing substances such as DNT is achieved according to the invention by a process which is characterized in that polyhydric alcohols with a weight fraction of the order of 3 to 9% are added to the mixture as a phlegmatizing agent after the gelling process, with which the Impact energy is significantly increased.
  • a weather explosive to mix a mixture of nitroglycerin, nitroglycol, dynamite cellulose and DNT after gelling ammonium nitrate, sodium chloride, guarameal and ethylene alcohol, the ethylene alcohol having a weight fraction below 3% in the guaremeal With dispersed in a weight fraction below 2%.
  • the ethylene alcohol which has 1 to 4 carbon atoms in the molecule and acts synergistically with respect to the guar flour, has the task of imparting antideflagrating properties to the guar flour in the nitroglycerin explosive.
  • propanetriol in the order of magnitude of 3-9% is added as the desensitizing agent.
  • butanediols in the order of magnitude of 3-9% are added as desensitizing agents.
  • a mixture of one or more of the desensitizing agents propanetriol (glycerol), monoethylene glycol (glycol) or butanediol is added in the order of 3-9%.
  • explosives in which polyhydric alcohols are used as desensitizing agents have a higher vapor volume than explosives containing DNT.
  • the higher swath volume contains less harmful nitrous gases due to the more favorable oxygen balance.
  • the other favorable properties of the gelatinous ammonium nitrate explosives such as good explosive power, good initiation ability, very good water resistance and sufficient storage life remain receive.
  • nitroglycol and 0.8% nitrocellulose are mixed until a gelatin forms.
  • 7% glycol, 68.1% ammonium nitrate, 2.1% wood flour, small amounts of color and inert substances are added until a homogeneous plastic mass is formed.
  • the recipes are characterized by an extremely high impact energy and the other advantages already mentioned, in the case of explosive properties that correspond to those of the gelatinous ammonium nitrate explosives formed with DNT.
