- W0-A9665 is distributed on August 22, 1996, and contains nitrogranidine and silicon oxide or aluminum oxide. Disclosure of the game.
- Nitrogen-containing organic compounds generally use an oxidizing agent in combustion when an oxidizing agent is used that generates only a chemical equivalent, that is, the amount of oxygen necessary to burn carbon, hydrogen and other elements in the compound molecule. It has the drawbacks that it generates a large amount of heat and has a high combustion temperature as compared with chemical products.
- an airbag inflator system not only the performance of the gas generating agent, but also the size of the system itself is such that it does not interfere with normal driving of the car. This is essential, but the combustion temperature during combustion of the gas generant is high This and the large amount of heat generated require additional parts for heat removal when designing a gas generator, and it is impossible to reduce the size of the gas generator itself.
- a gas generating agent having a characteristic that the combustion temperature is low during combustion and the calorific value is small is superior. Therefore, the known gas generating compositions as described above cannot be said to be satisfactory for application to a bag system.
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, have completed the present invention.
- the present invention is a gas generating composition containing nitroguanidine and an oxidizing agent comprising the following (a), (b) or a mixture thereof as essential components.
- the composition consists of a nitroglyzine and (b) or a nitrogluginine and (a) and (b).
- it contains 20-80% by weight of nitroguanidine and 80-20% by weight of oxidizing agent, or 25-40% by weight of nitroguanidine and 75-60% by weight of oxidizing agent including.
- the composition may further contain up to 5% by weight of binder, based on the total weight of the composition.
- the oxidizing agent preferably, (a) is a nitrate of an alkaline earth metal, and (a) is potassium strontium nitrate, and (a) is an alkali metal.
- (A) is nitric acid-lime, (b) is an oxide, (b) is copper oxide, or the oxidizing agent is nitric oxide. And copper oxide.
- the content of ditroguanidine in the gas generating composition of the present invention varies depending on the type of oxidizing agent and the oxygen balance, but is preferably 20 to 80% by weight. More preferably, it is 20 to 60% by weight. Most preferably, for example, when copper oxide is used as the oxidizing agent, the combustion temperature is 2200 K or less, and the amount of generated gas is 25 to 40% by weight, which is 1.2 mol / 100 or more.
- the above-mentioned (a), (b) or a mixture thereof is used as the oxidizing agent. It can be.
- the alkali metal or alkaline earth metal nitrate or nitrite of ⁇ a) include sodium nitrate, potassium nitrate, magnesium nitrate, and sodium nitrate.
- Metal salts or alkaline earth metal salts of nitric acid such as sodium, sodium nitrite, potassium nitrite, magnesium nitrite, magnesium nitrite Alkali metal salts or alkaline earth metal salts of nitrous acid such as tronium.
- oxides or double oxides of metals selected from copper, copper, iron, iron, manganese, nickel, zinc, molybdenum or bismuth in (b) is the object, specifically, C u O, C u 2 0, C o s 0, C o O, C oj O *, F ea 0 a, F e O, F e jO "M n 0 2, M n 2 0 3, M n 0. n i O, Z n O, M o O ,, C o M o O "B i a M o O .. B i 2 0 3 and the like.
- copper oxide is the most preferred.
- the oxidizing agent used in the present invention may be used in any combination of the above, but the content of the oxidizing agent in the gas generating composition is preferably 80 to 20% by weight, and more preferably. It is 80 to 40% by weight. Most preferably, for example, when oxidized water is used as the oxidizing agent, the combustion temperature is 2200 K or less, and the amount of generated gas is 75 to 60% by weight, which is 1.2 mol / 100 g or more.
- the gas generating composition of the present invention may further contain a base material.
- the binder used in the present invention include inorganic binders such as silica, alumina, and molybdenum disulfide, or microcrystalline cellulose, poval, and polymer binder.
- Organic binders such as ligomers may be mentioned. It is preferable that the content of the syrup in the gas generating composition of the present invention is 5% by weight or less.
- the gas generant composition of the present invention containing the nitrogenidine and the oxidizing agent has a lower combustion temperature as a whole as compared with the gas generant compositions disclosed so far, and The calorific value tends to be small.
- the composition of a combination of nitroguanidine and CuO is very excellent in these respects and is the most important composition.
- this composition can change the combustion rate and the pressure index by changing the oxygen balance.
