Description
Field that the present invention belongs to
The present invention relates to be used for being assemblied in automobile, aircraft etc., and relate to the inflator system that is used for this gas-generating agent composition with the gas generant composition in protection passenger's the gas-bag system.
Prior art
Developed at present replace poisonous sodiumazide compound as the gas generating agent in the air bag system.For example, JP-B 6-57629 discloses the gas generating agent that contains tetrazolium and triazole transition metal complex, Jp-A 5-254977 discloses the gas generating agent that contains the nitric acid triaminoguanidine, JP-A-6-239683 discloses the gas-generating agent composition that contains carbohydrazide, JP-A 7-61885 discloses and has contained nitrocellulose, the gas generating agent of potassium perchlorate and nitrogenous nonmetallic compound, JP-A 4-265292 discloses the gas generating agent that contains amino tetrazole and strontium nitrate, and US-A 5125684 discloses the gas generating agent that contains 15-30% cellulose-based binder such as Nitrocellulose and energy component materials.
Yet because the temperature of combustion of all these gas generating agents is all very high, the High Temperature Gas that burning produces can be damaged strainer or air bag or the gas that sprays from the pore of air bag can be scalded the passenger.In addition, in inflatable curtain (curtain formula shielding air bag), the new inflatable band or tubulose system that come into the picture in recent years, air bag must long-time inflation.Yet for the gas generating agent that produces high-temp combustion gas, gas can very fast contraction when it cools off, and makes it can not have satisfied performance.Under these situations, need have the gas generating agent of low combustion temperature.
About having the gas generating agent of low combustion temperature, JP-A 9-501137 discloses the gas generating agent that contains amino tetrazole and cupric oxide.Though reduced temperature of combustion with cupric oxide as oxygenant, the gas production rate of this gas generating agent is low, and needs a large amount of gas generating agents.In this respect, this gas generating agent is willing to not as the people.
The present invention is open
Therefore, an object of the present invention is to provide the gas-generating agent composition that can reduce temperature of combustion and improve gas production rate.
Another object of the present invention provides the inflator that uses said gas-generating agent composition.
The inventor finds: be combined in the compound that contains at least 25% Sauerstoffatom in the molecule and metal oxide and composite oxide of metal and can reduce temperature of combustion and improve gas production rate, and finished the present invention.
That is, the invention provides a kind of gas-generating agent composition, comprise at least a be selected from the compound that in molecule, contains at least 25% Sauerstoffatom act as a fuel and at least a material of metal oxide and composite oxide of metal that is selected from as oxygenant.
In addition, the invention provides the inflator that uses above-mentioned gas-generating agent composition.
In addition, calculate the content of Sauerstoffatom by following formula:
The molecular weight of (oxygen number * 16 in the molecule)/compound
By being combined in compound and metal oxide and the composite oxide of metal that contains at least 25% Sauerstoffatom in the molecule, gas generating agent of the present invention can reduce temperature of combustion and further high yield tolerance.As a result, can reduce the possibility that burning gas is damaged air bag or scalded the passenger, and also reduce the size of inflator.
