Definitions
- the present invention relates to a process for the preparation of gas-generating mixtures and the gas-producing mixtures which can be prepared by this process
- German patent application DE 195 05 568 A1 describes gas sets which do not contain sodium azide but nitrogen-containing compounds (fuels) from the group of the tetrazoles, triazoles, triazines, cyanic acid, ureas, their derivatives, derivatives or their salts.
- at least three compounds are provided as oxidizing agents, which are derived from peroxides, nitrates and perchlorates.
- Components that are suitable for influencing combustion and its speed by heterogeneous or homogeneous catalysis are used as combustion moderators.
- Such a test is a temperature shock test with numerous cycles in a temperature range from - 35 to + 85 ° C. In some cases, these tests may involve known ones gas-generating mixtures lead to intolerable changes in tablet strength.
- potassium chloride When using potassium compounds and in particular perchlorates, potassium chloride is formed when the gas set burns, which due to its fine distribution can lead to unfavorable reactions in vehicle passengers with allergic disposition (asthmatics).
- the object of the present invention was to eliminate these disadvantages of the prior art.
- the known gas sets are produced in a manner known per se. This is explained by way of example using the gas sets from DE 195 05 568 A.
- the components are mixed, for example dry, sieved, portioned and compressed into tablets.
- the rate of combustion can be adjusted via the grain shape and size of the bulk material obtained, for example, by breaking and sieving the fragments.
- the bulk material can be produced in large quantities and by mixing fractions with different ones dynamic liveliness can be adapted to the respective requirements when burning. Premixes with 2 or 3 components can also be used to increase safety or improve the mixing result.
- a mixture of oxidizing agent and additives can be prepared before it comes into contact with the nitrogenous compounds.
- the mixture can also be kneaded by moist components and subsequent granulation z. B. by passing through sieves, extrusions or the like.
- Binders such as water glass, inorganic rubber (phosphonitrile chloride) or even small proportions of organic binders such as acrylic resins, PTFE, guar gum can be used.
- gas-generating mixtures are generally produced simply by mixing pretreated components. Intimate homogeneity of the components with one another cannot be achieved in this way, so that the mixtures produced in this way often have disadvantages, for example when it comes to meeting the strict requirements with regard to the vapor compositions.
- the intimate homogeneity required to meet these requirements cannot be guaranteed simply by mixing the components.
- the technique, which is conventional in other areas, of producing mixtures of different components by simultaneously grinding these components, has not hitherto been applicable to the production of gas-generating mixtures because of the increased safety risk.
- components which act as passivators are the friction agents known per se and used as such in gas-generating mixtures, and components which are used per se in gas-generating mixtures in order to influence the combustion of the gas-generating mixture and its speed.
- Such components also referred to as combustion moderators and substances used as passivators in the context of the present invention in the grinding process, are metals, metal oxides and / or metal carbonates and / or metal sulfides.
- Boron, silicon, copper, iron, titanium, zinc or molybdenum can preferably be used as metals.
- Calcium carbonate can also be used.
- Sulfur, boron, silicon or ferrocene and its derivatives are also suitable. Mixtures of these passivators can also be used.
- These components which act as passivators in the grinding process in the sense of the invention, are evaporated into the gas phase by the temperatures occurring in the reaction occurring in the gas generator and can thus intervene in the reaction as combustion moderators themselves or as secondary products.
- the components are mixed particularly intimately and effectively when certain friction agents are used as passivators, for example iron oxide, aluminum oxide, preferably basic aluminum oxide, tin dioxide or titanium dioxide.
- oxidizing agents tungsten trioxide, cerium IV oxide, ammonium cerium nitrate and / or luteon nitrate
- passivators in the sense of the invention.
- part of the oxidizing agent itself acts as a passivator.
- the proportion of passivators in the mixture ultimately depends on the required degree of passivation and can be between 1 and 15% by weight of the mixture.
- the homogeneous gas-generating mixture which can be produced in this way according to the invention can then be pressed in a manner known per se. If a granulate is desired, the compacts are broken and classified into the desired grain sizes by subsequent sieving.
- the gas-generating mixtures which can be prepared according to the invention can contain nitrogen-containing compounds from the group of the tetrazoles, triazoles, triazines, cyanic acid, ureas, their derivatives, derivatives or their salts or their mixtures as fuel.
- the tetrazole derivatives 5-aminotetrazole, lithium, sodium, potassium, zinc, magnesium, strontium or calcium are preferred - 5-aminotetrazolate, 5-aminotetrazole nitrate, sulfate, perchlorate and similar compounds, 1- (4- Aminophenyl) tetrazole, 1- (4-nitrophenyl) tetrazole, 1-methyl-5-dimethylaminotetrazole, 1-methyl-5-methylaminotetrazole, 1-methyl-tetrazole, 1-phenyl-5-aminotetrazole, 1-phenyl -5-hydroxy-tetrazole, 1-phenyltetrazole, 2-ethyl-5-aminotetrazole, 2-methyl-5-aminotetrazole, 2-methyl-5-carboxyltetrazole, 2-methyl-5-methylaminotetrazole, 2-methyltetrazole, 2-phenyltetrazole , 5- (p-tolyl) tetrazole, 5-dially
- Nitroguanidine or 5-aminotetrazole is used as a particularly preferred component. Its salts are used as derivatives of 5-aminotetrazole, in which the acidic hydrogen atoms on 5-aminotetrazole are replaced like salts by toxicologically harmless elements such as calcium, magnesium or zinc. However, it is also possible to use compounds in which the cation is formed from ammonium, guanidinium and its amino derivatives. The proportion of these fuels in the mixture is 5 to 70% by weight, preferably 10 to 55% by weight.
- Nitrates preferably ammonium nitrate, nitrates of the alkali or alkaline earth metals, in particular lithium, sodium, potassium nitrate or strontium nitrate, and iron oxide, preferably in a particularly fine particle size distribution, are used as the oxidizing agent.
- Tungsten trioxide, cerium IV oxide, ammonium cerium nitrate and / or luteon nitrate can be used as further oxidizing agents. Mixtures of these oxidizing agents can also be used.
- the mixture according to the invention for gas production can contain the usual supplements, for example those which are suitable, the proportion of To reduce harmful gases such as nitrogen oxides and / or carbon monoxide or press, trickle, sliding aids or binders.
- additives can also contain fibers to increase the strength of the compacts, and to control the burning behavior of porosity-generating agents.
- a binder for example, an agent can be used as such. B. by thermoplastic deformation or after activation with a suitable solvent z. B. by immersion, spraying or in solvent vapor to the strength of the moldings.
- the tablets can also be coated with a binder on the outside. This can be done by dipping or spraying with a binder dissolved in a solvent. This can achieve:
