Definitions

  • the present invention is a fire extinguishing composition, the when burning produces an aerosol.
  • European Patent Application EPO 0 627 244 discloses a fire extinguishing composition described, consisting of a thermally dispersible component, an oxidizing agent, an oxygen-containing binder and various additives consists. During the burning of this composition, an aerosol is formed, which is used for Fire extinguishing can be used.
  • Fire-extinguishing compositions containing these components are therefore in higher temperature ranges (> 85 ° C) can not be used.
  • Embodiments are characterized in the subclaims.
  • German utility model G 94 16 112.7 describes a gas generator fuel, which can also be used as an extinguishing agent.
  • active binder he is not in the sense of the present invention to be understood inactive Biriderrüttel.
  • compositions according to the invention contain as active, oxygen-containing Binder a combination of inactive and active binder.
  • inactive Binders can be, for example, various waxes, cellulose, various resins, Polymers, rubbers and the like, or mixtures of these inactive binders be used.
  • Nitro compounds can be used as the active binder be, which have a high thermal capacity.
  • compositions of the invention are characterized by being good are flammable, guarantee stable combustion, until 150 ° C are thermally stable and show a long-term storage capacity of more than 10 years.
  • the present invention more particularly relates to fire extinguishing compositions Oxidizing agent, oxygen-containing binder and additives in which the oxygen-containing binder from a combination of inactive and active Binder exists.
  • the inactive binder is selected from the group of different waxes, Cellulose, various resins, polymers, such as polybutadiene, rubbers or from mixtures of these inactive binders.
  • the active binder is selected from the group of nitro compounds containing a have high thermal stability, preferably from the group of nitramine blowing agents, particularly preferably from the group nitroguanidine, from the group of polymeric polynitroaromatics according to DE 27 53 555, hexogen, octogen or from Mixtures of these compounds.
  • the oxidizing agent of the invention Compositions are selected from the group potassium nitrate, sodium nitrate, Ammonium nitrate, potassium perchlorate, sodium perchlorate, ammonium perchlorate or their mixtures.
  • the technical additions are selected from the group Carbon, silica, aluminum, alumina, iron, iron oxide or out their mixtures. If necessary, the compositions of the invention also plasticizers from the group of phthalates, for example Dibutyl phthalate or diamyl phthalate or mixtures of such plasticizers added become.
  • fire extinguishing compositions Oxidizing agent, oxygen-containing binder and additives in which the oxygenated Binder from a combination of inactive and active binder wherein the inactive binder is selected from the group of various Waxes, cellulose, various resins; Polymers, rubbers or mixtures of these inactive binder and the active binder from the group of polymers Polynitroaromaten from polymers with 4 to 20 recurring structural units on the base of mononuclear or polynuclear aromatics having at least two nitro groups per aromatic nucleus, hexogen, octogen or mixtures of these compounds is selected.
  • compositions Oxidizing agent, oxygen-containing binder and additives in which the oxygen-containing Binder from a combination of inactive and active binder wherein the inactive binder is selected from the group of various Waxes, cellulose, polybutadiene, rubbers or mixtures of these inactive Binder and the active binder of nitroguanidine.
  • compositions according to the invention contain from 40 to 70% by weight of oxidizing agent, 3 to 20% by weight of inactive binder, 10 to 40% by weight of active binder, 1 to 10% by weight of technical additives and optionally up to 10% by weight Plasticizer, for example 40 to 70% by weight potassium nitrate, 3 to 20% by weight Rubber, 10 to 40% by weight of hexogen and 1 to 10% by weight of carbon or 40 to 70% by weight of potassium nitrate, 3 to 20% by weight of rubber, 10 to 40% by weight of nitroguanidine and 1 to 10% by weight of carbon or 40 to 70% by weight of potassium nitrate, 3 to 20% by weight Polybutadiene, 10 to 40 wt .-% nitroguanidine and 1 to 10 wt .-% carbon or 40 to 70% by weight of potassium nitrate, 3 to 20% by weight of polybutadiene, 10 to 40% by weight Hexogen and 1 to 10 wt .-% carbon.
  • compositions according to the invention are prepared, for example by intimate mixing of the individual components and to a good free-flowing Kneaded granules.
  • the granules thus obtained have a diameter of 1 to 2 mm, are easy to dose and can be in known pressing devices to the desired shapes. It is also possible to use these granules extrude or process by injection molding.
