Definitions

  • the present invention relates to the use of electrically ignitable initial explosives for lighting booster or propellant charges or for generating pressurized gas.
  • electrically ignitable igniter compositions which contain potassium salts of trinitrophenol or trinitroresorcinol or lead salts of trinitroresorcinol as initial explosives, zinc peroxide as oxidizing agent and fibers of a conductive material.
  • the DE 195 33 487 A describes ignition elements containing lead azide, diazodinitrophenol, silver azide, trizinate and / or picrate as initial explosives, an oxidizing agent and a heat-dissipating additive.
  • Ditetrazoles substituted with aromatic nitro compounds having at least three nitro groups are disclosed as explosive and flammable substances which are used either alone or with other known explosive and flammable substances.
  • ignition charges that contain special initial explosives and peroxides that can be used to ignite thermal charges. Due to their composition, they are preferably ignited by mechanical action. An electric ignition of these sets is possible only under special conditions.
  • this object is achieved by using electrically ignitable salts of dinitrobenzofuroxan as initial explosives in a primer for the electrical lighting of boosters or propellant charges or for generating compressed gas.
  • Preferred salts which may be used are, for example, the potassium salt of dinitrobenzofuroxan called.
  • the salts of the dinitrobenzofuroxan can contain at least one additional electrically ignitable initial explosive and, if appropriate, an oxidizing agent and optionally binders, reducing agents, secondary explosives, components which contribute to the reaction and / or inert substances.
  • the additional initial explosives usable for this purpose are preferably selected from 2-diazo-4,6-dinitrophenol, 4-diazo-2,6-dinitrophenol, dipicrylditetrazole, from the salts of 2-diazo-4,6-dinitroresorcinol, 4- Diazo-2,6-dinitroresorzins, trinitrophenol and / or trinitrozoresin.
  • Preferred salts which may be used are, for example, the potassium and strontium salts of trinitrophenol and of trinitroresorzin. If a small proportion of lead in the windrows can be tolerated, the lead salts of trinitroresorzin in normal or basic form in amounts up to 20 wt .-% may be included in the mixture.
  • the initial explosives may be present in amounts of from 20 to 70% by weight. Mixtures of these initial explosives can also be used. They can be used in both fine-grained and coarse-grained state.
  • the oxidizing agent is selected according to the invention from zinc peroxide, potassium nitrate and / or potassium perchlorate.
  • Zinc peroxide is preferably used with an active oxygen content of more than 12.3% (cf. DE-PS 29 52 069 ).
  • the oxidizing agent is used according to the invention in amounts of from 5 to 50% by weight.
  • the oxidizing agent can be used in both fine-grained and coarse-grained.
  • primer compositions according to the invention may also contain binders, reducing agents, secondary explosives, components which contribute to the reaction and / or contain inert substances.
  • Suitable reducing agents are the reducing agents known per se in igniter compositions which bring about an improvement in the ignitability. Suitable examples are boron, titanium, zirconium, magnesium, cerium magnesium, cerium silicon, aluminum / magnesium or calcium silicide powder. Mixtures of these reducing agents are also usable. The proportion of the reducing agent may according to the invention constitute up to 20% by weight.
  • Secondary explosives for example octogen, amino compounds of nitrated aromatics, for example of trinitrobenzene, such as mono-, di- or triaminotrinitrobenzene or diaminohexanitrodiphenyl, and furthermore the acylation products of these compounds, for example hexanitrooxanilide or hexanitrodiphenylurea, hexanitrostilbene, may be used as further components which contribute to the reaction.
  • trinitrobenzene such as mono-, di- or triaminotrinitrobenzene or diaminohexanitrodiphenyl
  • acylation products of these compounds for example hexanitrooxanilide or hexanitrodiphenylurea, hexanitrostilbene
  • Hexanitrodiphenyloxid, Hexanitrodiphenylsulfid, Hexanitrodiphenylsulfon, Hexanitrodiphenylamin, tetranitrocarbazole, tetranitroacridone, polyvinyl nitrate, nitrocellulose or pentaerythritol tetranitrate can be used.
  • Particularly preferred is nitrocellulose. These components may be included in amounts up to 30% by weight.
  • moderators in quantities of up to 10% by weight.
  • a moderator for example, Ca-resinate can serve.
  • materials of conductive material can be used. Both carbon and a metal conducting the electric current or an alloy, for example brass, can serve as the conductive material.
  • the fabrics are used in fibrous form.
  • Usable metal fibers are, for example, those of iron or copper. The proportion of fibers can range between 0.5 and 20% by weight.
  • Suitable inert substances are the substances known per se in ignition systems, which are also used to coordinate the properties of these sets with the particular intended use.
  • tin dioxide is called.
  • the inert substances include other binders, for example PVB, waxes or PE, adhesives and dyes.
  • the proportion of inert substances in the igniter compositions according to the invention can be up to 20% by weight.
  • the preparation of the ignition charges or the preparation of the ignition mixtures is carried out according to methods known per se by mixing the individual constituents with the binder dissolved in a solvent or the secondary explosive having binding agent properties. This mixing can be done by conventional methods by stirring, kneading or similar distribution methods. In this case, the ignition charges or the igniter mixtures fall as brechte mass.
  • the first charges to be used according to the invention not only fulfill the function of a standard ignition charge, but can be used directly without additional boost charge. This is generally done by directly applying a first charge by means of a metering device, such as pipettes, syringes or the like.
  • the ignition charges are portioned in perforated plates by careful application of the water moistened substances or mixtures. After ejection from the mold, drying and possibly light pressing of the ignition charge thus formed takes place.
  • the first charges to be used according to the invention can, if appropriate in combination with a second charge, for example by an ignition / ignition element in accordance with DE-A 19637587 , But also by igniting / igniting elements of the type of a gap, glow wire or metal layer element igniter and all caused by sparks or laser light ignitions are made to ignite.
  • initial explosives for lighting booster or propellant charges or for generating compressed gas, in which the initial explosives are electrically ignitable and salts of dinitrobenzofuroxan are.
  • the potassium dinitrobenzofuroxanate in normal and / or basic form can preferably be selected as the salt of the dinitrobenzofuroxane.
  • the initial explosive may be compressed and / or a suspension of inert material may be provided.
  • the invention relates to the use of dinitrobenzofuroxan electrically ignitable salts together with at least one additional initial explosive for lighting booster or propellant charges or for generating compressed gas, wherein the primer is electrically ignitable and may contain at least one oxidizing agent.
  • the initial explosives to be used according to the invention may additionally comprise binders, reducing agents, secondary explosives, components which contribute to the reaction, moderators, materials of conductive material and / or inert substances.
  • the usable additional initial explosives are electrically ignitable and selected from 2-diazo-4,6-dinitrophenol, 4-diazo-2,6-dinitrophenol, Dipikrylditetrazol, from the salts of 2-diazo-4,6-dinitroresorzin, 4-diazo -2,6-dinitroresorzins, trinitrophenol or trinitroresorin or mixtures of these initial explosives, the oxidizing agents may be selected from zinc peroxide, potassium nitrate and / or potassium perchlorate, the reducing agents may be selected from boron, titanium, zirconium, magnesium, cerium magnesium
  • the secondary explosive can be selected from octogen, from amino compounds of nitrated aromatics, preferably mono-, di- and / or triaminotrinitrobenzene or diaminohexanitrodiphenyl, from acylation products of these compounds, preferably hexanitrooxanilide and / or hexanitrodiphen
  • the initial explosives are used according to the invention in methods for lighting booster or propellant charges or for the electrical generation of compressed gas, wherein the initial explosive is ignited electrically.
  • 2-Diazo-4,6-dinitrophenol (diazodinitrophenol or diazole) is prepared by diazotization of sodium picrate.
