Abstract
Gas generating agent used for safety gas bag of the present invention is made of organic compounds containing nitrogen and oxo halate, the invention provides superior impact ignition quality, combustionvelocity and gas generating capacity, and reach the gas generating agent used for safety gas bag of lower temperature of combustion.
Description
The present invention relates to the gas-evolution agent that a kind of air bag is used.
When vehicles such as automobile bump against at a high speed, locate at the handle portion of vehicle or windshield etc. and cause the casualties in order to prevent that the occupant from hitting, inside at handle or panel board is incorporated with Nylon Bag, it can perception collides and produces and expand, and improves growth sharp for the demand of this air bag system day by day because of the security requirement to automobile etc.
The moment of air bag after perception collides makes gas-evolution agent fire burns by electric or mechanical means igniting, and the gas that produces expands airbag.And the gas-evolution agent sheet of moulding or discoid normally, used gas-evolution agent must have suitable combustionvelocity.Combustionvelocity slowly then deficiency thereby can not be used as air bag so that the instantaneous expansion of airbag.In addition, if gas-evolution agent is a powder stock, then have and impact the character of catching fire, so-called impact ignition quality is for the ballistic sensitivity of catching fire, its oversensitiveness then can have bigger explosion hazard in manufacturing processedes such as married operation or moulding process, so from safety say be do not wish such, and desirable be that to impact ignition quality low as much as possible.
In addition, do not require that gas-evolution agent has too high temperature of combustion.This is because common airbag sponges impact when the occupant is clashed into, and then in order to help the occupant to deviate from, allows internal gas after expanding emit and shrink.The temperature that the temperature of combustion height is then emitted gas is just high, thereby gas is burnt the occupant, or boiled hole descends its function on airbag, even the danger of airbag burning causing vehicle fire is increased.
The gas-evolution agent that the air bag in past is used is well known that with sodiumazide as gas generation base, and comprises for example oxygenant [TiO
2, MnO
2, Fe
2O
3, metal oxides such as CuO, NaNO
3, KNO
3, Cu(NO
3)
2Deng nitrate, KClO
4, NaClO
4Deng perchlorate, KClO
3, NaClO
3Deng oxymuriate or the like], metallic reducing agent [Zr, Mg, AL, Ti etc.], refrigerant [Na
2CO
3, K
2CO
3, CaCO
3, FeSO
4Deng], pH value conditioning agent [ferric sulfate etc.], mechanical property rising agent [MoS
2, KBr, graphite etc.] etc. additive.
Because above-mentioned is that the gas-evolution agent of base mainly produces nitrogen with the sodiumazide, suitable combustionvelocity is arranged again, lower high-performances such as temperature of combustion, thereby be widely used as the gas-evolution agent of air bag, but sodiumazide exists following problem:
(1) have because of decomposing or burning causes the danger of fire, thereby (when mixing with oxygenant, make when granular preparation etc.) causes the danger of fire because when manufacturing is arranged, so security control that must the implementation strictness.
Generate Na when (2) decomposing, Na and water reaction produce hydrogen, and be on fire easily, also can produce toxic smog, therefore handles very difficulty.
(3) because and oxidant reaction, produce Na
2O, and inductor (NaOH etc.) toxic ingredient handle during manufacturing and must pay close attention to.
(4) sodiumazide burns or decomposes the gas that is produced because the very high concentration of toxic gases of nitrogen concentration is very low, thereby no problem in practicality, but people still wish to have lower toxic ingredient concentration in the hope of perfectly sound.
(5) the rough sodiumazide as gas-evolution agent has water absorbability, and moisture absorption afterfire performance reduces, and therefore must have to prevent to draw wet countermeasure.
(6), thereby need the promising facility investment that guarantee that safety is carried out owing to toxic, dangerous high material.
These problems in view of sodiumazide, people wish the gas-evolution agent that has a kind of air bag to use, it has with sodiumazide is the identical or lower impact ignition quality of gas-evolution agent of base, identical or higher combustionvelocity and gas generating capacity are arranged, it is the lower danger and the toxicity of gas-evolution agent of base that the sodiumazide lower than temperature of combustion arranged, and more cheap.
On the other hand, people to the nitrogen compound for the gas-evolution agent base has carried out all tests, for example, propose use Zr, oxygenants such as metallic reducing agent such as Mg and potassium perchlorate, Potcrate carry out redox reaction, Sheng Re and gas generation base is burnt.Enumerated with smokeless powder, cellulose nitrate, azo-dicarboxylic acid amides as gas generation base, the arsyl guanidine, thio ureas etc. (are seen special public clear 49-9734, special public clear 49-21171 communique), but the combustionvelocity of aforesaid method is still impracticable as air bag, the mixture of metallic reducing agent and oxygenant has very high impact ignition quality in addition, thereby has and handle to go up dangerous greatly problem, and can envision it very high temperature of combustion is arranged.
Though and the spy opens to disclose in the clear 50-118979 communique and uses the azo-dicarboxylic acid amides, oxygenants such as organic compounds containing nitrogen such as three hydrazino triazines and potassium permanganate, Manganse Dioxide, barium dichromate, barium peroxide are formed the airbag gas-evolution agent, but use potassium permanganate, it impacts ignition quality during oxygenants such as Manganse Dioxide, combustionvelocity can not meet the demands, use barium dichromate, during oxygenants such as barium peroxide, then can generate toxic ingredient in the gas.
One of purpose of the present invention provides a kind of gas generating agent used for safety gas bag, and it has with sodiumazide is the identical or lower impact ignition quality of gas-evolution agent of base.
Another object of the present invention provides that a kind of to have with sodiumazide be the identical or higher combustionvelocity of the gas-evolution agent of base and the airbag gas-evolution agent of gas generating capacity.
