Definitions
- the invention relates to a pyrotechnic mixture for producing an aerosol containing at least one oxidizing agent, at least one reducing agent and an evaporable, mist-forming mixture.
- the aerosol can z. G. for daytime signaling, as a non-lethal agent in police and military deployment scenarios and as a camouflage nebula.
- Such a pyrotechnic mixture (pyrotechnic composition) is known, for example, from EP 0 329 718 B1.
- pyrotechnic composition is known, for example, from EP 0 329 718 B1.
- the inorganic salts of potassium chloride and sodium chloride are used as vaporizable, mist-forming substances, the inorganic salts of potassium chloride and sodium chloride.
- a pyrotechnic mixture in which a organic compound (cinnamic acid) is used as fog-forming substance, for the evaporation of a relatively low temperature of the order of 300 ° C is required.
- a disadvantage of this mixture however, that harmful noxious, cyclic hydrocarbon compounds such as styrene occur in the forming mist.
- the invention has for its object to provide a pyrotechnic mixture for generating an aerosol that is simple and inexpensive to produce and human and ecotoxicologically harmless as possible.
- the invention is based on the claim of producing a humanoid and ecotoxicologically harmless aerosol which has good optical activity (high extinction, low transmission).
- the temperature required for the evaporation of the mist-forming substance mixture should be as low as possible. This has the advantage that a special insulation of the mist container is not required.
- the flame should be as low as possible, so that in combination with the low burning temperature, the fire load on the environment is low.
- the pyrotechnic composition is then used in sealed containers, containers, etc., the z. B. made of metal or cardboard and have at least one opening.
- the pyrotechnic composition is ignited by means of a corresponding ignition charge.
- the released thermal energy is used to evaporate the aliphatic monocarboxylic acid and the emulsifier.
- the mist set burns with a relatively low temperature and low flame.
- the mist container itself does not have to be particularly insulated; the fire load on the environment is relatively low.
- the pyrotechnic mixture can be added to a heat-resistant, porous filler which is chemically inert to the other constituent constituents. It may be z. B. natural, amorphous silica (diatomaceous earth) or natural clays such. B. Kaolin hand.
- a heat-resistant, porous filler which is chemically inert to the other constituent constituents. It may be z. B. natural, amorphous silica (diatomaceous earth) or natural clays such. B. Kaolin hand.
- a fatty acid and the emulsifier Upon evaporation of the carboxylic acid and the emulsifier, they flow out of the container opening to form microscopically small mixing particles which form a fatty phase.
- Fat phases of fatty acid and emulsifier are known and provide the basis for oil in fat or fat in oil emulsions, the z. B. in the food or cosmetic industry. According to the intention, these fat phases should store or store water,
- the particles vaporized on firing the pyrotechnic mixture behave in air like condensation nuclei, d. H. they can physically store or store water from the air and form an aerosol of solid and liquid particles that scatters and absorbs the visible light like a natural mist.
- the pyrotechnic mixture according to the invention has the advantage that the aerosol formed from the vaporizable solids, in particular the monocarboxylic acids, already scatter the light so well that a good optical effectiveness is given even at low atmospheric humidity.
- This pronounced property of the active ingredient components gives the pyrotechnic mixture certain climate independent properties. This property is further enhanced by the fact that the pyrotechnic mixture according to the invention during firing, d. H.
- the active ingredient monocarboxylic acids and emulsifiers specified in the pyrotechnic mixture according to the invention are known as such and can be found in the food industry outside the industry.
- carboxylic acids and emulsifiers are usually approved for use in foods or ingredients of natural foods. As a result, these components are easily available.
- the active ingredient components in turn contain no cyclic hydrocarbons.
- the active components in the aerosol, carboxylic acids and emulsifiers, are themselves human and ecotoxicologically harmless.
- palmitic acid hexadecanoic acid
- stearic acid octadecanoic acid
- / or behenic acid docosanic acid
- the level of the melting point of the monocarboxylic acids depends on the carbon chain length.
- pyrotechnic mixtures especially for military applications, must withstand temperatures above 64 ° C over an extended period of time and must not lose their safety and function.
- the chemical stability of the low-melting mono-carboxylic acids is given in the proposed pyrotechnic mixture, they have the disadvantage that they begin to melt below 60 ° C. in the mixture. As a result, the solid structure of the pyrotechnic mixture changes - usually disadvantageous.
- the melting point of low melting waxes can be increased by admixing a high melting polymer, e.g. B. with polyethylene glycol.
- a high melting polymer e.g. B.
- polyethylene glycol polyethylene glycol
- polyethylene glycol polyethylene glycol
- stearic acid from 58 ° C to 88 ° C raises when both substances are mixed in a mixing ratio of 50:50.
- mixing ratios of the polyethylene with stearic acid from 5:95 to 10:90 results in a melting point reduction by about 4 ° C, d. H.
- These mixtures melt below the melting points of the individual components.
- the melting point rises above the melting point of low melting stearic acid.
- the mixed melting point is approx. 78 ° C.
- the low-melting monocarboxylic a higher melting substance preferably polyethylene glycol or polyethylene in proportions of 10% - 20%, at.
- chlorates from the group of alkali metals can be used.
- potassium chlorate has proven to be advantageous as an oxidizing agent.
- the reducing agent may be a carbohydrate or a mixture of different carbohydrates from the groups of mono- or di-saccharides.
- the reducing agent may be glucose, sucrose and lactose.
- the pyrotechnic mixture may additionally contain a filler.
- Hydrated aluminum silicates in particular natural kaolins such as bolus alba, have proven particularly advantageous for the composition according to the invention.
- the components of the pyrotechnic mixture can be mixed and processed in powdered form.
- the mixture can also be granulated without addition of a binder with water.
- the powder mixture or the granulate can then be filled directly into a corresponding container, etc.
- the mixture is pressed together with a primer in the / the container, etc.
- the mist set or the mist body can be produced easily and inexpensively.
- the burning speed depends on a. on the size of the surface (grain size, geometry) of the granules.
- this granulate can be used in a container filled.
- the granules may still be coated with a pyrotechnic igniter mixture in order to improve the firing of the granules.
- the pyrotechnic mixture but also a binder can be added, preferably from the group of cellulose esters, dextrins or similar. comes.
- precautionary neutralizing salts may be added to the mixture to prevent the formation of auto-ignitable chloric acid.
- the neutralizing agents are preferably carbonates or Hydroxidcarbonate the alkaline earth group, such as. For example, calcium carbonate and magnesium hydroxide carbonate, or aluminum hydroxide. Usually, an admixture of these neutralizing agents of 2% to the pyrotechnic mixture is sufficient. Depending on the added amount of the neutralizing agent, they can, similar to aluminum silicate, regulate the firing of the pyrotechnic mixture and replace part of the aluminum silicate. To reduce the friction and impact sensitivity of the pyrotechnic mixture, this graphite or boron nitride can be mixed.
- the container can also be a throwing body, a grenade or a grenade carrying the container, which consist of a multiplicity of different materials.
- the container can also be a throwing body, a grenade or a grenade carrying the container, which consist of a multiplicity of different materials.
- certain materials such. B. special plastics but also inorganic residues from surface treatments of metallic components, at temperatures above 64 ° C and / or presence of residual moisture by formation of the dreaded chloric acid from the alkali chlorate can lead to spontaneous combustion of the pyrotechnic mixture, these are not used.
- cellulose esters in proportions of 1-5% can be added to the mixtures and the water-moist mixture subsequently granulated.
