Definitions

  • the subject of the present invention is a pyrotechnic agent.
  • Pyrotechnic agents in the context of the invention are substances or mixtures of substances which can develop a pyrotechnic effect.
  • the subject of the present invention is a pyrotechnic agent which can be used as a thermal ignition agent.
  • thermal pre-ignition agents are, for example, safety systems, preferably thermal fuses in gas generators or separating elements for batteries.
  • security systems are again preferably used in motor vehicles.
  • Thermal preignition agents are pyrotechnic substances or mixtures which, inter alia, have the task of controlling the generally very thermally stable gas-generating mixtures of the gas generator in the event of a vehicle fire.
  • thermal preignition agents are the use as a pyrotechnic set in separators, preferably for battery terminals. These separators should interrupt the power supply in case of fire, especially a vehicle fire, or in a motor vehicle accident in which the gas generator is triggered.
  • Nitrocellulose, propellant powder derived therefrom or the mixtures based on nitrotriazolone and guanidine nitrate described in the patent application DE 197 30 873 A1 are used as thermal premature igniters, for example. These mixtures show ignition temperatures of about 160 0 C and are insufficiently long-term stability in the case of nitrocellulose.
  • Another object of the present invention was to provide a pyrotechnic agent that can be used in battery terminal isolators.
  • azotetrazolates are used as component according to the invention.
  • the azotetrazolate component employed here is amino guanandine 5,5'-azotetrazolate (C 4 H 4 Ni ⁇ ), AGATZ for short, and guanidine 5,5'-azotetrazolate (C 41 Hi 2 Ni 6 ), GATZ for short.
  • the azotetrazolate components may be used either alone or in mixtures with each other and / or with other components.
  • the structural formulas of AGATZ and GATZ are as follows:
  • Aminoguanine 5,5'-azotetrazolate (C 4 Hi 4 Ni ⁇ , AGATZ).
  • Guanidine 5,5'-azotetrazolate (C 4 , Hi 2 Ni 6 , GATZ).
  • the deflagration point of the pure AGATZ is 209 ° C, that of the GATZ is 24O 0 C.
  • the deflagration temperatures in the range of 165 ° C to 195 ° C can be controlled and the deflagration temperatures of the mixtures can be lower than that of the individual components.
  • additives can be used:
  • Oxidizing agents (individually or in mixtures)
  • Nitrates of alkali or alkaline earth metals or ammonium such as sodium, potassium or ammonium nitrate, perchlorates of alkali or alkaline earth metals or of ammonium, peroxides of alkali or alkaline earth metals or zinc.
  • Nitrogen-containing compounds (individually or in mixtures)
  • diamidine nitrate diaminoguanidine azotetrazolate, triaminoguanidine azotetrazolate or ammonium azotetrazolate.
  • High-energy additives (singly or in mixtures) Hexogen, octogen, nitrocellulose.

  • Burn-off moderators, stabilizers and processing aids (individually or in mixtures)
  • Ferrocene and derivatives acetonyl acetates, salicylates, barium carbonate, strontium carbonate, magnesium carbonate, melamine, zinc oxide, zinc carbonate, silicates, silica gels, silicas, for example Aerosil (Degussa), boron nitride.
  • the production and processing takes place according to known and customary methods. These include, for example, kneading, extrusion, extrusion, tableting or granulation.
  • pyrotechnic agent containing as component one or more azotetrazolates
  • azotetrazolate component is selected from amino guanandine 5,5'-azotetrazolate (AGATZ) and guanidine 5,5'-azotetrazolate (GATZ) or mixtures of both;
  • a pyrotechnic agent wherein the proportion of the azotetrazolate component is 100% by weight
  • K ⁇ ausland ⁇ OZ05026 doc a pyrotechnic agent, the proportion of the azotetrazolate component being from 10 to 99% by weight, preferably from 15 to 60% by weight, particularly preferably from 20 to 50% by weight;
  • a pyrotechnic agent containing 1 to 90 wt .-%, preferably 40 to 85 wt .-%, particularly preferably 50 to 80 wt .-% of an additive or mixtures of several additives;
  • a pyrotechnic composition the additives being selected from: ammonium picrate, aminoguanidinium picrate, guanidinium picrate, aminoguanidinium stannate, guanidinium typhnate, nitroguanidine, nitroaminoguanidine, nitrotriazolone, derivatives of tetrazole and / or salts thereof, nitraminotetrazole and / or its salts, aminoguanidine nitrate, diamino guanidine nitrate, Triaminoguanidine nitrate, guanidine nitrate, dicyandiamide nitrate, diaminoguanidine azotetrazolate, triaminoguanidine azotetrazolate, ammonium azotetrazolate; Nitrates of the alkali and / or alkaline earth metals and / or ammonium, perchlorates of the alkali and / or alkaline earth metal
  • the oxidizing agent is selected from one or more of the nitrates of the alkali and / or alkaline earth metals and / or ammonium, the perchlorates of the alkali and / or alkaline earth metals and / or ammonium, the peroxides of the alkali and / or alkaline earth metals and / or zinc;
  • a pyrotechnic agent wherein the nitrogen-containing compound is selected from one or more of ammonium picrate, aminoguanidinium picrate,
  • a pyrotechnic agent wherein the energetic additives are selected from one or more of hexogen, octogen and / or nitrocellulose;

  • Table 1 lists the compositions of 27 different pyrotechnic agent blends. The components were weighed in the stated weight ratios (in percent by weight (% by weight)) in plastic containers and homogenized for 30 minutes in a tumble mixer.
  • Table 2 shows the deflagration points, friction and impact sensitivities of the mixtures.
  • the measurement of the friction and impact sensitivities was carried out according to methods of the Federal Institute for Materials Research (BAM), while the measurement of the deflagration points with the thermogravimetric analysis (Mettler) was carried out at a heating rate of 10 ° C. per minute.
