Definitions
- the present invention relates to an acid-free, gas-generating Composition, in particular for use in security devices for motor vehicles.
- Gas generating compositions used in safety devices used for motor vehicles mostly consist of a fuel based on sodium azide and an oxidizing agent. However, due to the toxicity of sodium azide, it was premature started looking for alternatives to the azide-containing gas generators To look for mixtures.
- US-A-5 608 183 describes a gas generating mixture containing between about 30 and 85 percent by weight of a fuel and between about 15 and about 70 percent by weight of an oxidizing agent.
- At least 60% by weight of the fuel consists of the nitrate of an acidic polyamine or a C 2 -C 3 -alkyldiamine, such as, for example, the nitrates of urea, guanidine, aminoguanidine, diaminoguanidine, semicarbazide, ethylenediamine, 1,3-propanediamine or 1, 2-propanediamine, or mixtures thereof.
- the oxidizing agent comprises at least 60% by weight of basic copper nitrate and / or cobalt triamine trinitrate. The mixture is processed in a wet process.
- the gas generating mixture known from US-A-5 608 183 has however, an insufficient willingness to ignite and a too low Burn-up speed. Due to the high proportion of basic Copper nitrate is also an increased proportion of toxic gases in the released Detectable gas mixture. Processing the mixture in A wet process requires additional drying stages and is therefore expensive.
- The. German utility model No. 298 06 504 represents a gas generating Composition ready, the one of at least two components existing fuel mixture in a proportion of 20 to 60 wt .-% and an oxidizer mixture consisting of at least three components in a proportion of 40 to 80% by weight, based in each case on the total composition, includes.
- the fuel mixture of the known composition is from 5 to 95% by weight of a guanidine compound, 5 to 95 % By weight of a heterocyclic organic acid, for example Cyanuric acid, as well as 0 to 20% by weight of other fuels.
- the oxidizer mixture of the known composition consists of one or more transition metal oxides in a proportion of 20 to 70% by weight and 10 to 50% by weight of basic copper nitrate and 2 to 30 % By weight metal chlorate, metal perchlorate, ammonium perchlorate, alkali nitrate, Alkaline earth nitrate or mixtures thereof.
- an additional fuel such as However, cyanuric acid
- the Composition is therefore for use in gas generators for the Driver's side unsuitable because of the shorter distance between high burn-up speeds for the vehicle occupant and the vehicle internals to be favoured.
- the additional fuels used must have a lower oxygen balance than guanidine nitrate also a higher proportion of oxidizer to balance the mixture and to achieve an optimally reduced harmful gas emission be used.
- the higher proportion of oxidizer leads to a increased solids content in the gas mixture and thus to an increased Particulate emissions.
- the present invention provides such a composition ready, the one consisting of one or more components Fuel in a proportion of 20 to 60 wt .-% and one of at least three components consisting of an oxidizer mixture in a proportion of 40 up to 80 wt .-%, each based on the total composition.
- the composition is characterized in that the fuel a guanidine compound in a proportion of at least 95% by weight and another fuel component in a proportion of 0 to less than 5 wt .-%, each based on the fuel.
- the oxidizer mixture consists of one or more transition metal oxides in a proportion of 20 to 80 wt .-%, basic copper nitrate in a proportion of 0 to 50% by weight, metal chlorate, metal perchlorate, Ammonium perchlorate or mixtures thereof in a proportion of 1 to 15 % By weight and alkali nitrate, alkaline earth nitrate or mixtures thereof a proportion of 1 to 15 wt .-%, each based on the oxidizer mixture.
- Preferred guanidine compounds are guanidine carbonate, guanidine nitrate, Guanidine perchlorate, aminoguanidine nitrate, diaminoguanidine nitrate, Triaminoguanidine nitrate, nitroguanidine or mixtures thereof used.
- the further fuel component is preferably an organic one Compound that has an oxygen balance of more than -90%.
- Cyanuric acid is particularly preferred as a further fuel component, Urea, oxamide, urazole, alloxan, alloxantin and parabanic acid or mixtures thereof.
- oxygen balance is to be understood as the amount of oxygen in percent by weight which is released when a compound or a mixture is completely converted to CO 2 , H 2 O, Al 2 O 3 , B 2 O 3 , etc. (O 2 overbalancing) , If the available oxygen is not sufficient for this, the shortfall necessary for complete conversion is given with a negative sign (O 2 under-balancing).
- the transition metal oxide present as a component of the oxidizer mixture can be selected from the group consisting of Cr 2 O 3 , MnO 2 , Fe 2 O 3 , Fe 3 O 4 , CuO, Cu 2 O or mixtures thereof.
- the oxidizer mixture preferably contains a mixture of Fe 2 O 3 and CuO, in addition to the other components of the oxidizer mixture.
- the Fe 2 O 3 is preferably present in a proportion of at least 4% by weight, particularly preferably in a proportion of at least 9%, based on the overall composition.
- the simultaneous use of Fe 2 O 3 and CuO enables a further reduction in the proportion of toxic gases in the combustion products.
- the composition may also include conventional processing aids a proportion of up to 5% by weight, based on the total composition, included, the processing aids preferably from the consisting of the flow aids, pressing aids and / or lubricants Group are selected.
- a preferred composition according to the invention consists of 30 to 60% by weight guanidine nitrate, 0 to 3.15% by weight cyanuric acid, 15 to 30% by weight CuO, 15 to 30% by weight basic copper nitrate, 1 to 5% by weight. -% ammonium perchlorate and 1 to 5 wt .-% alkali and / or alkaline earth metal nitrate, each based on the total composition.
- Part of the CuO can preferably be replaced by Fe 2 O 3 .
- compositions according to the invention stand out the previously known mixtures due to improved combustion behavior, and in particular through an extremely low particle emission in combination with a high burning rate. they are therefore particularly suitable for use in driver airbag systems.
- the improved burning behavior of the compositions according to the invention is achieved through the use of at least one organic compound favored as a fuel from the group of guanidine compounds.
- the use of guanidine nitrate is particularly preferred because of its favorable oxygen balance of - 26.2%. Compared to others organic compounds or their mixtures with guanidine nitrate less oxidizer is thus required to balance the mixture. This measure therefore already results in lower particle emissions reached.
- the proportion of basic copper nitrate in the oxidizer mixture should in any case be at most 50% by weight, based on the oxidizer mixture.
- the mixture In addition to a high combustion rate and extremely low carbon monoxide and NO x emissions, the mixture is easy to ignite and has excellent retention properties with regard to solid combustion residues. A higher proportion of basic copper nitrate is undesirable since this would in particular increase the NO x proportions in the gas inadmissibly.
- a particularly preferred gas generating according to the invention Mixture consists of 40 to 55% by weight guanidine nitrate, 0 to 2.9% by weight Cyanuric acid, each 15 to 30 wt .-% copper oxide and basic copper nitrate as well as 1 to 5% by weight of ammonium perchlorate and alkali or Alkaline earth metal. This composition ensures due the low proportion of cyanuric acid is one for driver airbag systems sufficient burning rate.
- a mixture of 47.1 parts guanidine nitrate and 52.9 parts basic copper nitrate was prepared according to the procedure described in Example 1 of US-A-5,608,183. The mixture showed poor ignitability and only a slow burning rate. The NO x portion of the gas generated measured in the test jug was 1300 ppm.
