に関するものである。FIELD OF THE INVENTION The present invention relates to a gas generating agent for an air bag. Specifically, it has an appropriate burning rate, a relatively low burning temperature, suitable for an air bag to protect in-house occupants from the impact at the time of a collision of a transportation system such as an automobile or a sudden stop. Not about gas generants.

る中その需要が飛躍的に増大しつつある。2. Description of the Related Art In order to prevent an occupant from being killed or injured by a collision with a steering wheel or a windshield when a vehicle such as an automobile collides at high speed,
A so-called airbag system in which a bag incorporated in a steering wheel and / or a dashboard is inflated upon detection of a collision, the demand for the airbag system is rapidly increasing as safety requirements for automobiles and the like further increase.

グを膨張させる。かかるガス発生剤は適度な燃焼速度を
有することを必須とする。燃焼速度が遅いとバッグが瞬
時に膨張せず、エアバッグとしての用をなさない。In an airbag system, an ignition agent is ignited electrically or mechanically instantly after detecting a collision, and then a gas generating agent is ignited and burned to generate gas to inflate the bag. It is essential that such a gas generating agent has an appropriate burning rate. If the burning rate is slow, the bag will not expand instantly and will not be used as an airbag.

からである。Further, the gas generating agent is required to have a combustion temperature not too high. The reason for this is that an air bag normally releases some of its internal gas and somewhat contracts in order to absorb the shock when the occupant collides with the inflated air bag or to assist the occupant to escape. However, if the combustion temperature is high, the gas temperature will be high and the occupant will be burned.
This is because there is a high risk that a hole may be formed in the bag to deteriorate its function, or the bag may burn to cause a vehicle fire.

る。Conventionally, as a gas generating agent for an air bag, sodium azide is used as a base, and for example, an oxidizing agent (CuO, Fe 2 O 3 , Mn
Metal oxides such as O 2 , nitrates such as NaNO 3 and KNO 3 , KClO

が、アジ化ソーダ及びそれを基剤としたガス発生剤には
以下のような問題点がある。A gas generating agent based on sodium azide is widely used as a gas generating agent for an air bag because of its excellent properties such as a moderate burning rate and a relatively low burning temperature. The gas generating agent based on has the following problems.

る。Sodium azide has a risk of causing a fire due to rapid decomposition or combustion. In particular, when a large amount of fire is generated during handling of a large amount of gas generating agent, such as storage, there is a high risk of a large-scale disaster, and strict measures are required for safety management. In addition, since a toxic component such as Na 2 O is generated when the gas generating agent is burned, there is a concern about environmental pollution, especially at the time of large-scale disposal and disposal expected in the future. Also, due to the good water solubility of sodium azide, the risk of contamination of ground and groundwater is increasing, and heavy metal azides that are highly explosive when contacted with heavy metals such as lead, copper, brass, etc. May generate.
