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.
特許文献１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。特許文献２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。特許文献３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。特許文献４には、ＧＺＴ，ＴＡＧＮ（硝酸トリアミノグアニジン），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。特許文献５には、硝酸グアニジン等の燃料、塩基性硝酸銅及びグアガムからなるガス発生剤組成物が開示されている。 Patent Document 1 discloses a composition of a tetrazole or triazole compound containing hydrogen and an oxygen-containing oxidizing agent. Patent Document 2 discloses a gas generant composition comprising a metal salt of bitetrazole containing no hydrogen and an oxidizing agent containing no oxygen.

Yes. Patent Document 5 discloses a gas generant composition comprising a fuel such as guanidine nitrate, basic copper nitrate and guar gum.
しかし、上記の非アジド系ガス発生剤組成物は、燃焼後、残渣（ミスト）を生成するので、それがエアバッグ内に流入しないようにするため、フィルターを用いる必要がある。その際、ガス発生剤組成物の燃焼後、フィルターで捕集されやすい形状のスラグを形成し易いような組成とする方法がある。 However, since the non-azide gas generant composition generates a residue (mist) after combustion, it is necessary to use a filter in order to prevent the residue from flowing into the airbag. At that time, there is a method of making the composition easy to form a slag having a shape easily collected by a filter after the gas generating agent composition is burned.
特許文献６には、硝酸グアニジン等の燃料、塩基性硝酸銅、アルミナ等の金属酸化物からなる組成物に、シリカをスラグ形成剤として添加し、良好なスラグ（クリンカー）を生成させることが開示されている。特許文献７には、テトラゾール化合物等の燃料、硝酸ストロンチウムにガラス粉末を添加することによって、燃焼温度を低下させ、その結果、ＮＯｘ、ＣＯを低減すること、及び固体スラグが形成されることが開示されている。特許文献８には、アルカリ金属アジド、酸化剤からなるペレット、シリカ含有物質からなる粒を混合して用いることで、ミストを低減することが開示されている。
本発明は、上記従来技術の組成物と比べると、よりスラグを形成し易い新規なガス発生剤組成物を提供することを課題とするものである。 It is an object of the present invention to provide a novel gas generant composition that can form slag more easily than the above-described prior art composition.
本発明は、課題の解決手段として、（ａ）ガラス粉末と、（ｂ）水酸化アルミニウム及び／又は水酸化マグネシウムを含有することを特徴とするガス発生剤組成物を提供する。 As a means for solving the problems, the present invention provides a gas generant composition comprising (a) glass powder and (b) aluminum hydroxide and / or magnesium hydroxide.
更に本発明は、課題の他の解決手段として、下記（ａ）〜（ｄ）成分を含有することを特徴とするガス発生剤組成物を提供する。 Furthermore, this invention provides the gas generating composition characterized by containing the following (a)-(d) component as another solution means of a subject.

（ｃ）燃料としての有機化合物
（ｄ）含酸素酸化剤
また本発明は、課題の他の解決手段として、上記のガス発生剤組成物から得られる単孔円柱状、多孔円柱状の成型体を提供する。単孔又は多孔の成型体は、貫通孔でも、非貫通孔でも良い。
(A) Glass powder (b) Aluminum hydroxide and / or magnesium hydroxide (c) Organic compound as fuel (d) Oxygen-containing oxidizer The present invention provides the above gas generating agent as another means for solving the problems. A single-hole cylindrical or porous cylindrical molded body obtained from the composition is provided. The single hole or porous molded body may be a through hole or a non-through hole.
更に本発明は、他の課題の解決手段として、上記のガス発生剤組成物及び成型体を用いたエアバック用インフレータを提供する。 Furthermore, the present invention provides an inflator for an air bag using the gas generating composition and the molded body as a means for solving other problems.
本発明のガス発生剤組成物及びその成型体は、ガラス粉末を含有しているため、燃焼残渣が固化してスラグを形成するので、燃焼残渣がミストになり、インフレータ外に放出されることが防止される。この効果は、ガラス粉末と水酸化アルミニウム及び／又は水酸化マグネシウムの併用により、更に高められる。 Since the gas generating composition of the present invention and the molded body thereof contain glass powder, the combustion residue is solidified to form slag, so that the combustion residue becomes mist and is released outside the inflator. Is prevented. This effect is further enhanced by the combined use of glass powder and aluminum hydroxide and / or magnesium hydroxide.
本発明で用いる（ａ）成分のガラス粉末は、ガス発生剤組成物の燃焼時において溶融状態となり、燃焼後の温度低下に伴い、瞬時に固化する。この過程で、他の成分に由来の燃焼残渣を融解し、固化することでトラップし、スラグを形成する。このため、燃焼残渣がミストとなってインフレータ外部に放出され、エアバッグ内に流入することが防止できる。 The glass powder of component (a) used in the present invention is in a molten state at the time of combustion of the gas generant composition, and instantly solidifies as the temperature decreases after combustion. In this process, combustion residues derived from other components are melted and solidified to trap and form slag. For this reason, it can prevent that a combustion residue turns into mist, is discharge | released outside the inflator, and flows in into an airbag.
ガラス粉末は、金属酸化物及び／又は非金属酸化物との混合物からなる非晶質体であるものが好ましい。金属酸化物は、二酸化ケイ素、酸化ナトリウム、酸化カリウム、酸化カルシウム、酸化マグネシウム、酸化バリウム、酸化鉛、酸化ホウ素、酸化アルミニウム等から選ばれるものが好ましい。非金属酸化物は、酸化リン、酸化テルル、酸化ビスマスから選ばれるものが好ましい。 The glass powder is preferably an amorphous material composed of a mixture of a metal oxide and / or a nonmetal oxide. The metal oxide is preferably selected from silicon dioxide, sodium oxide, potassium oxide, calcium oxide, magnesium oxide, barium oxide, lead oxide, boron oxide, aluminum oxide and the like. The non-metal oxide is preferably selected from phosphorus oxide, tellurium oxide, and bismuth oxide.
ガラス粉末としては、石英ガラス、９６％石英ガラス、ソーダ石灰ガラス（窓ガラス、板ガラス、瓶ガラス、電球用等）、鉛ガラス（電気用、光学用、工芸用等）、アルミノホウケイ酸ガラス、ホウケイ酸ガラス（低膨張、低損失、タングステン封着等）、アルミノケイ酸塩ガラス、リン酸塩ガラス、カルコゲン化ガラス等から選ばれるものが好ましい。 Glass powder includes quartz glass, 96% quartz glass, soda lime glass (window glass, plate glass, bottle glass, for bulbs, etc.), lead glass (electrical, optical, industrial use, etc.), aluminoborosilicate glass, borosilicate Those selected from acid glass (low expansion, low loss, tungsten sealing, etc.), aluminosilicate glass, phosphate glass, chalcogenide glass and the like are preferable.
特にこれらの各種ガラス粉末は、その組成により軟化点が異なるため、燃料としての有機化合物、含酸素酸化剤及び他の添加剤との組み合わせによる組成物の燃焼温度に合わせて、軟化点が最適な範囲となるガラス粉末を選択することが望ましい。本発明では、特に軟化点の低いガラス粉末を用いることが好ましく、軟化点が１０００℃以下のものが好ましく、５９０℃以下のものがより好ましく、５５０℃以下のものが更に好ましい。軟化点の低いガラス粉末を用いると、スラグ形成効果が高められるので、ミストがより生成し難くなる。 In particular, since these various glass powders have different softening points depending on their compositions, the softening point is optimal in accordance with the combustion temperature of the composition in combination with an organic compound as a fuel, an oxygen-containing oxidant, and other additives. It is desirable to select a glass powder that falls within the range. In the present invention, it is preferable to use a glass powder having a particularly low softening point, preferably a softening point of 1000 ° C. or lower, more preferably 590 ° C. or lower, and even more preferably 550 ° C. or lower. When glass powder having a low softening point is used, the slag forming effect is enhanced, so that it is difficult to generate mist.
このような軟化点の低いガラスとしては、リン酸塩ガラス（Ｐ２Ｏ５を含むほか、ＣａＯ、Ｂ２Ｏ３、ＳｉＯ２、Ａｌ２Ｏ３、Ｆｅ２Ｏ３、ＭｇＯ、Ｎａ２Ｏ、Ｋ２Ｏ等から選ばれるものを含むもの）、下記一般式（Ｉ）で表されるものを用いることができる。 As such a glass having a low softening point, phosphate glass (including P 2 O 5 , CaO, B 2 O 3 , SiO 2 , Al 2 O 3 , Fe 2 O 3 , MgO, Na 2 O, which include those selected from K 2 O, etc.) can be used those represented by the following general formula (I).
ｘＭｎＯ−ｙＳｉＯ２−ｚＡｌ２Ｏ３ （Ｉ）
〔式中、ｘ、ｙ、ｚは、それぞれのモル数を示す。〕
一般式（Ｉ）中のｘ、ｙ、ｚの割合は、ｘが３５〜５０モル％、ｙが３０〜６０モル％、ｚが５〜２０モル％が好ましく、ｘが４０〜４５モル％、ｙが４０〜５０モル％、ｚが１０〜１５モル％がより好ましい。
xMnO-ySiO 2 -zAl 2 O 3 (I)
[Wherein, x, y and z represent the number of moles of each. ]
The ratio of x, y and z in the general formula (I) is such that x is 35 to 50 mol%, y is 30 to 60 mol%, z is preferably 5 to 20 mol%, x is 40 to 45 mol%, More preferably, y is 40 to 50 mol% and z is 10 to 15 mol%.
ガラス粉末の粒径は、５０％粒径として、好ましくは１０〜３００μｍ、より好ましくは１０〜１００μｍ、更に好ましくは１０〜５０μｍである。 The particle size of the glass powder is preferably 10 to 300 μm, more preferably 10 to 100 μm, and still more preferably 10 to 50 μm as a 50% particle size.
ガス発生剤組成物中におけるガラス粉末の含有量は、好ましくは０．１〜２０質量％であり、より好ましくは０．５〜５質量％である。ガラス粉末の含有量が上記範囲内であると、組成物のガス発生効率が余り大幅に低下されることなく、上記したようなスラグ形成作用が好適に発揮される。 The content of the glass powder in the gas generant composition is preferably 0.1 to 20% by mass, more preferably 0.5 to 5% by mass. When the content of the glass powder is within the above range, the slag forming action as described above is suitably exhibited without significantly reducing the gas generation efficiency of the composition.
本発明で用いる（ｂ）成分の水酸化アルミニウムと水酸化マグネシウムは、それぞれを単独で用いることができ、併用することもできる。（ｂ）成分としては、水酸化マグネシウムが好ましい。 The component (b) aluminum hydroxide and magnesium hydroxide used in the present invention can be used alone or in combination. As the component (b), magnesium hydroxide is preferable.
（ｂ）成分の水酸化アルミニウムと水酸化マグネシウムは、毒性が低く、分解開始温度が高く、熱分解すると、大きく吸熱し、酸化アルミニウム又は酸化マグネシウムと水を生成する。このため、水酸化アルミニウム及び／又は水酸化マグネシ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、燃焼後には、有毒な窒素酸化物と一酸化炭素の生成量が少なくなる。また、水酸化アルミニウム又は水酸化マグネシウムの分解により生じた酸化アルミニウム又は酸化マグネシウムは、（ａ）成分のガラス粉末と共に、スラグ形成作用もする。 The components (b), aluminum hydroxide and magnesium hydroxide, have low toxicity, high decomposition start temperature, and when thermally decomposed, they absorb a large amount of heat and produce aluminum oxide or magnesium oxide and water. For this reason, the inclusion of aluminum hydroxide and / or magnesium hydroxide lowers the combustion temperature of the gas generant composition and reduces the amount of toxic nitrogen oxides and carbon monoxide produced after combustion. In addition, aluminum oxide or magnesium oxide produced by the decomposition of aluminum hydroxide or magnesium hydroxide has a slag forming action together with the glass powder of component (a).
