Definitions
- the invention relates to solid gas generator fuels based on Guanidine compounds on suitable supports.
- JP H5-254977 is based on gas generator fuels for airbags of triaminoguanidine nitrate (TAGN), which also contains oxidizing agents such as May contain alkali and alkaline earth nitrates, nitrites, chlorates or perchlorates. Molybdenum sulfide can be contained as a further component as a binder.
- TAGN triaminoguanidine nitrate
- Molybdenum sulfide can be contained as a further component as a binder.
- the advantage of using TAGN instead of the known sodium azide is in the non-toxicity and also good stability of TAGN, which is also in Connection with heavy metals, no salts sensitive to friction and impact forms.
- the rate of combustion of the gas generator fuels is said to vary by Pressing pressure during the production of pellets or tablets from the Component mixture may be possible.
- the object of the present invention is compared to JP H5-254977 to provide improved gas generator fuels, the Burning behavior can be set in a targeted manner and that is good when burning retain slag and the formation of toxic gases on one Limit the minimum.
- the gas generator fuels are said to be thermally stable, good ignitable, fast - even at low temperatures - burning and easy to store be and ensure a high gas yield.
- these should Gas generator fuels reduce the size of the generator housing and thus their weight reduction compared to known with sodium azide enable operated generators.
- TAGN Carbonates, hydrogen carbonates or nitrates of guanidine, aminoguanidine, diaminoguanidine or triaminoguanidine (TAGN) or mixtures thereof can be used as component (A).
- TAGN is preferably used.
- TAGN is practically non-toxic (LD 50 > 3500 mg / kg rat), not hygroscopic, not very water-soluble, thermally stable, burning at low temperature and of low sensitivity to impact and friction.
- the gas yield from the combustion of TAGN is very high, with a large proportion of nitrogen gas being generated.
- 1 to 50% by weight of the TAGN can be replaced by nitroguanidine.
- the cost of component (A) can thus be reduced and favorable combustion behavior can be achieved, since nitroguanidine has a lower combustion rate than TAGN.
- component (B) alkali metal or alkaline earth metal nitrates, ammonium nitrate and mixtures thereof can be used. Potassium nitrate is preferably used. Potassium nitrate is non-hygroscopic, non-toxic, enables a high gas yield and low burning temperature when burned.
- Component (A) is in the mixture of (A) and (B) in an amount of about 20 to 55, preferably about 50 to 55% by weight, component (B) in an amount of about 80 to 45, preferably about 50 up to 45% by weight.
- Component (A) is preferably present in an amount of approximately 50 to 55% by weight and component (B) in an amount of approximately 50 to 45% by weight.

- the preferred carrier substance is silica with a pH from about 7.
- Oxygen-supplying carrier substances such as iron (III) oxide, cobalt oxides, manganese dioxide and copper (II) oxide or mixtures thereof can also be used as component (C).
- the preferred oxygen-supplying carrier substance is iron (III) oxide.
- Component (C) is present in an amount of 5 to 45, preferably about 8 to 20% by weight, based on the total amount of components (A) and (B). If iron (III) oxide is used as the oxygen-supplying carrier substance (C), it is present in an amount of about 20 to 40, preferably about 25 to 35,% by weight, based on the total amount of components (A) and (B).
- Component (C) serves to moderate the burnup, i.e. to adjust the Burning rate At the same time, the slag or Improved melt formation.
- the slag formation is, for example, at Airbag absolutely necessary.
- An airbag consists essentially of a gas generator housing that with the gas generator fuel, usually in tablet form, and one Initial igniter (squib) for igniting the gas generator fuel, as well as a Gas bag.
- Suitable detonators are, for example, in Us-Ps 49 31 111 described.
- the gas bag which is initially folded into small pieces, is after the initial ignition filled with the gases generated when the gas generator fuel burns and reaches its full volume in a period of about 10-50 ms.
- the Hot sparks, melts or solids escape from the gas generator in the gas bag must be largely prevented, as it will destroy of the gas bag or injury to vehicle occupants. This is achieved through slag formation.
- respirable dust-like particles decreased from the gas generator of an airbag could escape.
- respirable dust particles a diameter of about 6 ⁇ m or less.
- the oxygen-supplying Carrier substances also suppress the formation of toxic gases such as Carbon monoid when burning.
- the gas generator fuel may also contain, as component (D), a binder which is soluble in water at room temperature.
- binders are cellulose compounds or polymers made from one or more polymerizable olefinically unsaturated monomers.
- cellulose compounds are cellulose ethers, such as carboxymethyl cellulose, methyl cellulose ethers, in particular methyl hydroxyethyl cellulose.
- a usable methylhydroxyethyl cellulose is CULMINAL (R) MHEC 30000 PR from Firm Aqualon.
- Suitable binders are polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and polycarbonates.
- Component (D) is based on the total amount of components (A) and (B) in an amount of about 0.1 to 5, preferably about 1.5 to 2.5% by weight in front.
- the binder (D) serves as a desensitizing agent and as a processing aid in the production of granules or tablets from the gas generator fuel. It also serves to reduce the hydrophilicity and to stabilize the Gas generator fuels.
- the tablets or pellets used in the gas generators from the Gas generator fuel can be produced by known methods, for example by extrusion, extrusion, in rotary presses or Tableting machines.
- the size of the pellets or tablets depends on the desired burning time in the respective application.
