Definitions

  • the invention relates to finely graded primers for igniters and Ignition elements.
  • the reaction products should be rich in particles where possible and these particles should be as hot as possible, and on the other hand a transport gas must be provided for the particles so that they penetrate the propellant charge as well as possible.
  • the transport gas should also have a correspondingly high temperature in order to maintain the particle temperature.
  • Igniters and igniters containing a pyrotechnic fuel based on B / KNO 3 or Ti / Ba (NO 3 ) 2 or TiH x / Ba (NO 3 ) 2 with x ⁇ 1 or Zr / Ba (NO 3 ) 2 and nitrocellulose but also igniters and igniters containing zirconium and potassium perchlorate generally meet these requirements.
  • the object of the present invention was to ignite and ignite elements the following, briefly called igniter elements, to be provided in addition to a sufficient performance depending on the application, finely graduated values for the Ignition sensitivity and the ignition insensitivity without the Ignition delay time is significantly impaired.
  • this object was achieved by providing and Combination of two different primers according to their properties Claims 1 to 12.
  • the 1st priming charge the so-called glow wire set, responsible for the electrical characteristics
  • the 2nd primer the so-called benefit rate
  • This heat-dissipating additive is selected from substances that As is known, can absorb heat and thereby heat the environment revoke. Examples of such substances can be inorganic or else be organic in nature, such as metals, metal compounds or organometallic Links.
  • metals or metal compounds are provided as heat-dissipating components.
  • Zirconium, aluminum, titanium and / or ferrotitanium are preferably used as metals.
  • Zircon is particularly preferred.
  • borides and hydrides of the metals mentioned can be used as metal compounds.
  • Zirconium boride and zirconium hydride are particularly preferred.
  • the glow wire sets of the ignition elements according to the invention contain at least one initial explosive, for example lead azide, diazodinitrophenol, silver azide, tricinate or picrate, preferably lead picrate, and an oxidizing agent, for example alkali metal or alkaline earth metal nitrate, chlorate, perchlorate, preferably KCIO 3 and / or KClO 4 , particularly preferably KClO 4 and a binder.
  • the binder is not only responsible for the connection of the individual components, but also for the temperature resistance of the ignition elements; they should have a temperature resistance of> 85 ° C.
  • Binders suitable according to the invention are therefore polyvinyl acetate, polysulfone or polyethersulfone. Polyvinyl acetate is preferably used. While the heat-dissipating additive is intended to increase sensitivity to ignition, the initial explosive used is responsible for ensuring the necessary sensitivity to ignition.
  • Glow wire sets of the first embodiment which are suitable according to the invention are composed of 20 to 80 parts of initial explosive, preferably lead picrate, 20 to 80 parts of a mixture of heat-dissipating additive and oxidizing agent and 1 to 6 parts of binder.
  • the mixture of heat-dissipating additive and oxidizing agent is composed of 60 to 90 parts of heat-dissipating additive and 10 to 40 parts of oxidizing agent.
  • a heat dissipating Component is a heat-dissipating initial explosive, preferably Silver azide, optionally in combination with other heat-dissipating agents Components such as metals, metal compounds or organometallic compounds intended.
  • Components such as metals, metal compounds or organometallic compounds intended.
  • zirconium, aluminum, Titanium and / or ferrotitanium, as metal compounds borides and hydrides, preferably Zirconium boride and zirconium hydride can be used.
  • the particular advantage in use of silver azide is that it is also a heat-dissipating additive acts and in its capacity as an initial explosive sensitivity to ignition improved.
  • the glow wire set consisting of 100 parts of silver azide and 1 to 6, preferably 4 parts Binder.
  • a binder with the same functions as the first Embodiment is preferably used polyvinyl acetate.
  • the power set according to the invention consists of a component that generates hot reaction particles, one of the above-mentioned oxidizing agents and one of the said binders.
  • a component that generates hot reaction particles zircon in its different crystal modifications, titanium or their mixtures is suitable.
  • KClO 3 and / or KClO 4 preferably KClO 4
  • the same substances are preferably used as binders as for the filament set.
  • Power sets suitable according to the invention are composed of 30 to 80 parts of zirconium, titanium or mixtures thereof, 20 to 70 parts of oxidizing agent, preferably KCIO4 and 1 to 6 parts of binder.
  • a mixture of 60 parts of zircon, 40 parts of KClO 4 and 4 parts of polyvinyl acetate is preferably used.
  • the primers according to the invention can be used alone or in a variety of ways Combination can be used.
  • the ignition elements according to the invention are produced, for example as follows.
  • the components of the glow wire set and the power set are sieved and in the binder dissolved in a suitable solvent slurried. If polyvinyl acetate is used as the binder, butyl acetate is one suitable solvent.
  • This slurry is made submersible, i.e. the Viscosity is adjusted accordingly. It is particularly important that the Do not sediment components during the dive. To ensure this For example, the primer sludge is carried out under safety precautions gentle stirring homogenized. Ignition elements are generally described in Form of squib.
  • a common squib exists, for example of two electrically conductive, elongated pole supports (lamellae), which are connected by means of a insulating web are connected and one that connects the pole carrier Glowbridge.
  • Such a primer body is repeatedly in the Primer slurry immersed in such a way that the 1st primer is the glow plug encloses. The diving process is repeated until the one for the respective Use sufficient amount of glow wire set mixture is applied.
  • Ignition charges have proven their worth in quantities of 6 to 10 mg. Between each Dives are given the solvent the opportunity to evaporate. After this Glow wire set is the same as the power set as a sheath around the glow wire set upset. For this sentence, too, the dive is repeated until the sufficient amount of power rate mix for the respective application is applied.
  • the primer weight for the entire squib is 50 to 100, preferably 65 to 85 mg proven. After the squib was dried for 24 hours is the squib with a 20% varnish from the respective binder coated and again dried for 48 hours.
  • the primers according to the invention can, depending on the binder used They are used for high temperature resistant igniters. Is considered Binding agents, for example polysulfone or polyether sulfone, can be used Ignition charges according to the invention used at temperatures of up to 250 ° C. become.
  • the ignition elements according to the invention are particularly suitable for the ignition of propellants that require long exposure times with a hot flame, as well as for insensitive propellants where hot metallic particles are required become.
