Definitions
- the invention relates to solid gas generator fuels (gas-generating mixtures), mainly for gas generator propellants for airbags and belt tensioners based on nitrogen-rich and low-carbon fuels, the solid gas generator fuels additionally containing a high-melting, essentially chemically inert slag trap in highly dispersed form, which acts as an internal filter acts and largely prevents the formation and escape of dust-like particles from the gas generator housing.
- solid gas generator fuels gas-generating mixtures
- the solid gas generator fuels additionally containing a high-melting, essentially chemically inert slag trap in highly dispersed form, which acts as an internal filter acts and largely prevents the formation and escape of dust-like particles from the gas generator housing.
- the invention thus relates to a method for trapping the liquid or solid combustion products or dust-like slag parts within the gas generator propellant immediately as they arise, so that one can manage with a simply structured filter package in the gas generator housing.
- the invention further relates to the use of catalysts based on platinum metals (Ru, Os, Rh, Ir, Pd, Pt) or metal alloys of platinum metals or copper on the slag catchers as carriers in solid gas generator fuels, in particular the use in solid gas generator propellants for airbags.
- platinum metals Ru, Os, Rh, Ir, Pd, Pt
- metal alloys of platinum metals or copper on the slag catchers as carriers in solid gas generator fuels, in particular the use in solid gas generator propellants for airbags.
- An airbag essentially consists of a gas generator housing, which is filled with the gas generator drive unit, usually in tablet form, and an initial igniter (squib) for igniting the gas generator drive unit, and a gas bag.
- squib initial igniter
- Suitable igniters are described, for example, in US Pat. No. 4,931,111.
- the initially small-folded gas bag is filled after the initial ignition with the gases generated when the gas generator propellant burns up and reaches its full volume in a period of about 10-50 ms.
- Escaping hot sparks, melts or solids from the gas generator into the gas bag must be largely prevented, since it could lead to the gas bag being destroyed or injuring vehicle occupants. This is achieved by binding and filtering the slag that is produced when the gas generator propellant is burned.
- DE-A-44 35 790 discloses gas generator fuels based on guanidine compounds on suitable carriers, which essentially have improved combustion behavior and improved slag formation.
- DE-A-44 35 790 gives no information on the use of high-melting, essentially inert slag catchers in highly dispersed form or of catalysts in gas generator propellants.
- the gas-generating mixture described in EP-B-0 482 852 contains a) a fuel selected from aminotetrazole, tetrazole, bitetrazole and metal salts of these compounds and triazole compounds and metal salts of triazole compounds; b) an oxygen-containing oxidation compound selected from alkali metal, alkaline earth metal, lanthanide and ammonium nitrates and perchlorates and alkali metal and alkaline earth metal chlorates and peroxides; and either c) a high temperature slag formation material selected from alkaline earth metal oxides, hydroxides, carbonates, oxalates, peroxides, nitrates, chlorates and perchlorates and alkaline earth metal salts of tetrazoles, bitetrazoles and triazoles, and d) a low temperature
- nitrates, perchlorates and chlorates and alkali metal salts of tetrazoles, bitetrazoles and triazoles or e) a high temperature slag formation material selected from transition metal oxides, hydroxides, carbonates, oxalates, peroxides, nitrates, chlorates and perchlorates; and f) a low temperature slag forming material which is silicon dioxide; wherein the amount of d) or f) is sufficient to result in the formation of a coherent mass or slag, but is not so high that a liquid with low viscosity is formed, it being understood that a single material for more than one of the Categories can serve.
- the main advantage of such a gas generator propellant lies in the favorable formation of a slag which can easily be filtered off from the gaseous combustion products formed. Another advantage is the high gas yield.
- Airbags described in which a primary gas mixture is initially created by the ignition of a gas generator propellant, which contains at least one tetrazole or triazole compound as fuel, and this primary mixture is diluted by mixing with ambient air in such a way that the content of toxic gaseous combustion products from the primary gas mixture is reduced to a toxicologically acceptable level.
- DE-C-44 01 213 describes gas-generating mixtures of a fuel, an oxidizer, a "catalyst” and a coolant, characterized in that the oxidizer Cu (NO 3 ) 2 -3Cu (OH) 2 and the catalyst a metal oxide or a metal oxide mixture or a metal mixed oxide is known.
- DE-C-44 01 214 also discloses gas-generating mixtures of similar compositions in which the catalyst consists of a metal or a metal alloy, preferably a pyrophoric metal or a pyrophoric metal alloy on a support.
- the carrier is a silicate, preferably a layered or framework silicate. Ag has proven particularly useful as a metal.
- the known fuels used include triaminoguanidine nitrate (TAGN), nitroguanidine (NIGU or NQ), 3-nitro-l, 2,3-triazol-5-one and especially diguanidinium-5,5'-azotetrazolate (GZT).
- the main advantage of the gas-generating mixtures described in the two above-mentioned German patents is said to be the lowering of the combustion temperature and the increase in the rate of combustion.
- the gas-generating mixtures described in DE-C-44 01 213 and DE-C-44 01 214 do not contain any low- or high-melting slag formers or slag scavengers according to the invention; rather, it claims that there is no need for slag formers. Contrary to this claim, the inventors of the present invention have found that the use of low-melting and high-melting slag formers, in particular the slag trap according to the invention, brings about a significant reduction in toxic gaseous combustion products.
- Part of the high-melting slag catcher according to the invention can act as a carrier for a platinum metal or for a metal alloy made of platinum metals and thus as a catalyst component.
- catalyst is used in a broader sense and represents an active component of the reaction which can itself be implemented and has a reaction-directing and / or reaction-accelerating effect.
- the definition of the catalyst also means that it is added to the reaction mixture in only a very low concentration.
- the proportion of "catalyst" in the gas-generating mixture is up to 30% by mass and is therefore an essential, also proportionate, component of the gas-generating mixture.
- the present invention is based on the object of providing improved gas generator fuels, in particular for airbags, the combustion behavior of which can be set in a targeted manner and which in particular the formation of 6
- the gas generator propellants made from the gas generator fuels should be thermally stable, easy to ignite, quick - even at low temperature - to be flammable and storable and ensure a high gas yield.
