Description
Technical field
The present invention relates to gas generant composition, its formed body and the air bag aerator that uses these of airbag restraint systems such as automobile.
Background technology
As the gas generant for air cell of automobile driver and conductor protector, used the composition that contains sodiumazide mostly in the past., sodiumazide to the toxicity [LD50 (oral-rat)=27mg/kg] of human body and the danger when using become problem.Instead it, safer so-called non-nitrine base system gas generant composition, developing the gas generant composition that contains various organic compounds containing nitrogens.
At United States Patent (USP) 4,909, in No. 549, the composition of the tetrazolium, triazole compounds and the oxygen containing oxidant that contain hydrogen is disclosed.At United States Patent (USP) 4,370, in No. 181, disclose by the metal-salt of the bistetrazole that does not contain hydrogen and do not contained the gas generant composition that the oxygenant of aerobic constitutes.At United States Patent (USP) 4,369, in No. 079, the metal-salt of the bistetrazole that does not contain hydrogen and the gas generant composition that base metal nitrate, alkali metal nitrites salts, alkine earth metal nitrate, alkaline earth metal nitrite or these mixture constitute are disclosed.At United States Patent (USP) 5,542, TAGN (triaminoguanidine nitrate), the gas-evolution agent that the catalyzer of the fuel of NQ (nitroguanidine), NTO etc., basic copper nitrate, reduction toxic gas and refrigerant constitute in No. 999, are disclosed by GZT.Open in flat 10-72273 number the spy and to disclose the gas-evolution agent that constitutes by bistetrazole metal-salt, tetrazole ammonium salt, amino tetrazole and ammonium nitrate.
, nitrine class gas-evolution agent usually, just generate nitrogen after burning, but not nitrine is a gas generant composition, and is general owing to containing carbon, nitrogen, oxygen, so after the burning, have the shortcoming that generates a small amount of deleterious carbon monoxide and oxynitride.In addition, non-nitrine class gas-evolution agent usually compares with nitrine class gas-evolution agent, and the temperature of combustion height when reality is used, needs a large amount of cooling materials.
In order to reduce the growing amount of burning deleterious carbon monoxide in back and oxynitride, known is to add metal oxide or DeNO in gas-evolution agent
XAgent (oxynitride depressant).For example, German Patent 4,401, No. 213 gas generant composition in order to reduce the growing amount of deleterious carbon monoxide and oxynitride, is the V that adds as catalyzer
2O
5/ MoO
3The heavy metal oxide of class., there is toxicity problem in heavy metal oxide, and when adding metal oxide, then the gas luminous efficiency of gas-evolution agent reduces.
In WO98/04507 number, disclose and used the DeNO of ammonium sulfate, volatile salt, urea etc.
XAgent and gas-evolution agent reduce the growing amount of the oxynitride in the combustion gases.In the time that ammonium sulfate can being to use, then generate deleterious oxysulfide, and there are the problem of thermostability in volatile salt, urea, and then add these DeNO
XDuring agent, the oxygenant of spent gas propellant has then increased the growing amount of deleterious carbon monoxide.
Disclosure of an invention
Therefore, problem of the present invention is to provide gas generant composition, and it is that the growing amount of deleterious carbon monoxide in the combustion gases of gas-evolution agent and oxynitride is few, low and its formed body of temperature of combustion and the air bag aerator that uses these.
The inventor finds, as the composition of gas generant composition, by selecting specific composition, can reduce temperature of combustion, and its result can reduce the growing amount of deleterious carbon monoxide, ammonia and oxynitride in the combustion gases.Thereby finished the present invention.
As the means that solve problem, the invention provides and contain following (a) composition, (b) composition and (c) composition, and then also contain (d) composition and/or (e) gas generant composition of composition as required.
(a) organic compound that acts as a fuel
(b) oxygen containing oxidant
(c) aluminium hydroxide
(d) binding agent
(e) additive of selecting from metal oxide, metal carbonate
And then, as the means that solve other problems, the invention provides and make the gas generant composition formed body that above-mentioned gas propellant composition molding obtains and use above-mentioned gas propellant composition or the air bag aerator of above-mentioned gas-evolution agent formed body.
Gas generant composition of the present invention and formed body thereof, temperature of combustion is low, and the growing amount of carbon monoxide and oxynitride is few during burning.
