Description
本発明は、自動車等のエアバック拘束システムに適したガス発生剤組成物、その成型体及びそれらを用いたエアバック用インフレータに関する。 The present invention relates to a gas generant composition suitable for an air bag restraining system of an automobile or the like, a molded body thereof, and an air bag inflator using them.
自動車における乗員保護装置としてのエアバッグ用ガス発生剤としては、従来からアジ化ナトリウムを用いた組成物が多用されてきた。しかし、アジ化ナトリウムの人体に対する毒性[LD50(oral−rat)=27mg/kg]や取扱い時の危険性が問題視され、それに替わるより安全ないわゆる非アジド系ガス発生剤組成物として、各種の含窒素有機化合物を含むガス発生剤組成物が開発されている。 Conventionally, a composition using sodium azide has been frequently used as a gas generating agent for an air bag as an occupant protection device in an automobile. However, the toxicity of sodium azide to the human body [LD 50 (oral-rat) = 27 mg / kg] and the danger during handling are regarded as problems, and as a safer so-called non-azide gas generant composition, there are various Gas generant compositions containing these nitrogen-containing organic compounds have been developed.
米国特許4,909,549号には、水素を含むテトラゾール、トリアゾール化合物と酸素含有酸化剤との組成物が開示されている。米国特許4,370,181号には、水素を含まないビテトラゾールの金属塩と酸素を含まない酸化剤とからなるガス発生剤組成物が開示されている。米国特許4,369,079号には、水素を含まないビテトラゾールの金属塩とアルカリ金属硝酸塩、アルカリ金属亜硝酸塩、アルカリ土類金属硝酸塩、アルカリ土類金属亜硝酸塩及びこれらの混合物からなるガス発生剤組成物が開示されている。米国特許5,542,999号には、GZT,TAGN(トリアミノニトログアニジン),NG(ニトログアニジン)、NTO等の燃料、塩基性硝酸銅、有毒ガスを低減する触媒とクーラント剤からなるガス発生剤が開示されている。特開平10-72273号には、ビテトラゾール金属塩、ビテトラゾールアンモニウム塩、アミノテトラゾールと硝酸アンモニウムからなるガス発生剤が開示されている。 U.S. Pat. No. 4,909,549 discloses a composition of a tetrazole or triazole compound containing hydrogen and an oxygen-containing oxidizing agent. US Pat. No. 4,370,181 discloses a gas generant composition comprising a metal salt of bitetrazole containing no hydrogen and an oxidizing agent containing no oxygen. U.S. Pat.No. 4,369,079 discloses a gas generant composition comprising a hydrogen-free metal salt of bitetrazole and an alkali metal nitrate, an alkali metal nitrite, an alkaline earth metal nitrate, an alkaline earth metal nitrite and a mixture thereof. It is disclosed. US Pat. No. 5,542,999 discloses a gas generating agent comprising a fuel such as GZT, TAGN (triaminonitroguanidine), NG (nitroguanidine), NTO, basic copper nitrate, a catalyst for reducing toxic gases, and a coolant agent. ing. Japanese Patent Application Laid-Open No. 10-72273 discloses a gas generating agent composed of a bitetrazole metal salt, a bitetrazole ammonium salt, aminotetrazole and ammonium nitrate.
しかし、アジド系ガス発生剤は、一般的に燃焼後に窒素しか生成しないが、非アジド系ガス発生剤組成物は、一般的に炭素、窒素、酸素を含むので、燃焼後において、有毒な一酸化炭素及び窒素酸化物を少量生成する欠点がある。また、非アジド系ガス発生剤は、一般的にアジド系ガス発生剤に比べれば、燃焼温度が高く、実際に使われると、大量のクーラントが必要となる。 However, azide-based gas generants generally produce only nitrogen after combustion, whereas non-azide-based gas generant compositions generally contain carbon, nitrogen, and oxygen, so that toxic monoxide after combustion. There is a disadvantage of producing small amounts of carbon and nitrogen oxides. Non-azide gas generants generally have a higher combustion temperature than azide gas generants, and require a large amount of coolant when actually used.
燃焼後における有毒な一酸化炭素及び窒素酸化物の生成量を減らすため、ガス発生剤に金属酸化物、又はDeNOx剤(窒素酸化物低減剤)を添加することが知られている。例えば、ドイツ特許4,401,213号のガス発生剤組成物は、有毒な一酸化炭素及び窒素酸化物の生成量を減らすために、触媒としてのV2O5/MoO3のような重金属酸化物を添加するものである。しかし、重金属酸化物の毒性問題があり、金属酸化物を添加すると、ガス発生剤のガス発生効率が低くなる。 In order to reduce the amount of toxic carbon monoxide and nitrogen oxides produced after combustion, it is known to add metal oxides or DeNOx agents (nitrogen oxide reducing agents) to the gas generating agent. For example, the gas generant composition of German Patent 4,401,213 adds a heavy metal oxide such as V 2 O 5 / MoO 3 as a catalyst to reduce the production of toxic carbon monoxide and nitrogen oxides. Is. However, there is a toxicity problem of heavy metal oxides, and when a metal oxide is added, the gas generation efficiency of the gas generating agent is lowered.
WO98/04507号には、硫酸アンモニウム、炭酸アンモニウム、尿素等のDeNOx剤とガス発生剤とを併用して、燃焼ガス中の窒素酸化物の生成量を低減することが開示されている。しかし、硫酸アンモニウムを使うと、有毒な硫黄酸化物を生成し、炭酸アンモニウム、尿素は、熱安定性に問題があり、更にこれらのDeNOx剤を添加すると、ガス発生剤の酸化剤を消耗し、有毒な一酸化炭素の生成量が増える。
従って、本発明の課題は、ガス発生剤の燃焼ガス中の有毒な一酸化炭素及び窒素酸化物の生成量が少なく、燃焼温度が低いガス発生剤組成物、その成型体及びそれらを用いたエアバック用インフレータを提供することにある。 Accordingly, an object of the present invention is to provide a gas generant composition having a low generation temperature of toxic carbon monoxide and nitrogen oxide in the combustion gas of the gas generant and a low combustion temperature, a molded body thereof, and an air using the same. The object is to provide a back inflator.
本発明者は、ガス発生剤組成物の組成として特定の組み合わせのものを選択することにより、燃焼温度を低下でき、その結果、燃焼ガス中の有毒な一酸化炭素、アンモニウム及び窒素酸化物の生成量を低減できることを見出し、本発明を完成した。 The inventor can reduce the combustion temperature by selecting a specific combination of gas generant compositions, resulting in the generation of toxic carbon monoxide, ammonium and nitrogen oxides in the combustion gas. The present invention has been completed by finding that the amount can be reduced.

The average particle size is measured by a particle size distribution method using laser scattered light. The measurement sample was obtained by dispersing a basic metal nitrate in water and then irradiating with ultrasonic waves for 3 minutes, obtaining a 50% cumulative value (D 50 ) of the number of particles, and calculating the average value of two measurements.

When it is a mixture of magnesium hydroxide and aluminum hydroxide, the content of magnesium hydroxide is 50% by mass or more.
水酸化マグネシウムと水酸化アルミニウムは、低毒性が要求される難燃剤、人工大理石の原料、洗剤用のほか、樹脂やゴムの添加剤としても使用されているもので、毒性が低く、分解開始温度が高いという特徴がある。更に熱分解するときに大きく吸熱し、酸化マグネシウム又は酸化アルミニウムと水を生成する。このため、水酸化マグネシウム又は水酸化アルミニウムを含有させることにより、ガス発生剤組成物の燃焼温度が低くなり、燃焼後における、有毒な窒素酸化物と一酸化炭素の生成量を少なくするように作用する。このような有毒ガスの低減作用は、特に酸化剤として(b−2)成分を使用したときに顕著となる。 Magnesium hydroxide and aluminum hydroxide are used as flame retardants that require low toxicity, raw materials for artificial marble, detergents, and as additives for resins and rubbers. Is characterized by high. Furthermore, when it thermally decomposes, it absorbs a large amount of heat and produces magnesium oxide or aluminum oxide and water. For this reason, the inclusion of magnesium hydroxide or aluminum hydroxide lowers the combustion temperature of the gas generant composition and acts to reduce the production of toxic nitrogen oxides and carbon monoxide after combustion.
