Definitions
- the present invention relates to a fire extinguishing composition which produces an aerosol when burned.
- a fire extinguishing composition which consists of a thermally dispersible component, an oxidizing agent, an oxygen-containing binder and various additives. When this composition burns off, an aerosol is formed which can be used to extinguish the fire.
- Fire extinguishing compositions containing these components can therefore not be used in higher temperature ranges (> 85 ° C).
- An object of the present invention was therefore to provide fire extinguishing compositions which do not have the disadvantages of the prior art.
- Embodiments are preferably characterized in the subclaims.
- compositions according to the invention contain, as an active, oxygen-containing binder, a combination of inactive and active binder.
- inactive binder a combination of inactive and active binder.
- various waxes, cellulose, various resins, polymers, rubbers and the like or mixtures of these inactive binders can be used as the inactive binder.
- Nitro compounds that have a high thermal resistance can be used as the active binder.
- compositions according to the invention are distinguished by the fact that they are readily ignitable, guarantee stable combustion, are thermally stable up to 150 ° C. and have a long shelf life of more than 10 years.
- the present invention relates in particular to fire extinguishing compositions comprising an oxidizing agent, an oxygen-containing binder and additives in which the oxygen-containing binder consists of a combination of inactive and active binder.
- the inactive binder is selected from the group of different waxes, cellulose, various resins, polymers, for example polybutadiene, rubbers or from mixtures of these inactive binders.
- the active binder is selected from the group of nitro compounds which have a high thermal resistance, preferably from the group of nitramine Blowing agents, particularly preferably from the group of 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 compositions according to the invention is selected from the group of potassium nitrate, sodium nitrate, ammonium nitrate, potassium perchlorate, sodium perchlorate, ammonium perchlorate or from mixtures thereof.
- the technical additions are selected from the group carbon, silicon dioxide, aluminum, aluminum oxide, iron, iron oxide or from their mixtures.
- plasticizers from the group of phthalates for example dibutyl phthalate or diamyl phthalate, or mixtures of such plasticizers can also be added to the compositions according to the invention.
- compositions according to the invention contain 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 hexogen and 1 to 10% by weight carbon or 40 to 70% by weight potassium nitrate , 3 to 20 wt.% Rubber, 10 to 40 wt.% Nitroguanidine and 1 to 10 wt.% Carbon or 40 to 70 wt.% Potassium nitrate, 3 to 20 wt.% Polybutadiene, 10 to 40 wt % Nitroguanidine and 1 to 10% by weight carbon or 40 to 70% by weight potassium nitrate, 3 to 20% by weight polybutadiene, 10 to 40% by weight hexogen and 1 to 10% by weight carbon.
- Plasticizer for example 40 to 70% by weight potassium nitrate, 3 to 20% by weight
- a preferred composition contains.
- compositions according to the invention are produced, for example, by intimately mixing the individual components and kneaded to form a free-flowing granulate.
- the granules thus obtained have a diameter of 1 to 2 mm, are easy to dose and can be pressed into the desired shapes in known pressing devices. It is also possible to extrude these granules or to further process them by injection molding.
