Abstract
Description
この出願は、2004年3月30日に出願された米国の仮出願番号60/557,473の利益を要求する。
本発明は、たとえば一般にガス生成システム、およびたとえば自動車の拘束システムのためのガス発生装置中で使用されるガス生成物質組成物に関する。
本発明は、燃焼に際して自動車の乗員の安全な拘束具を膨張させるのに有用なガスを急速に生成する、無毒性なガス生成組成物に関する。また、特には、本発明は熱的に安定な非アジ化物ガス生成物質であって、燃焼に際して受容可能な燃焼速度だけでなく、受容可能な火炎温度において比較的高いガス体積と固体の微粒子の比率を示す組成物に関する。
上記の課題は、カルボキシメチルセルロースアセテートブチレートのようなカルボキシアルキルセルロース化合物バインダーを含むガス生成組成物を含むガス生成システムによって解決される。別の言い方をすれば、本発明の組成物は、カルボキシル置換基およびアルキル基置換基の両方を有する主要なバインダーを含んでいる。当該技術分野において公知なように、また設計基準によって決定されるように、公知の燃料、酸化剤および他の添加物をこれらの組成物に組み入れることができる。本発明によれば、エアバッグインフレータおよび乗り物乗員保護システムのようなガス生成システムは、これらのガス生成組成物を組込む。本発明は、ガス燃焼生成物の生産を最適化し、固体の燃焼生成物を最小限にしつつ、減じられた吸湿性、熱的安定性、生産安全性および減じられた環境影響のような他の設計の要求を保持するガス生成物質組成物を含む。これらおよび他の利点は詳細な説明から明らかになる。
本発明は、燃料、酸化剤および主要なバインダーを含むガス生成物質組成物を含んでいる。主要なバインダーはセルロースポリマーの群から選ばれ、それぞれのポリマーバインダーはカルボキシル官能性、アルキル官能性および水酸基官能性を有している。別の言い方をすれば、この群から選ばれる好ましいバインダーは、カルボキシメチルセルロースアセテートブチレート(CMCAB)である。他のカルボキシアルキルセルロースバインダーも企図され、カルボキシル置換基およびアルキル基置換基の両方を有するセルロース骨格鎖を含んでいる化合物、およびそれらのカリウム、ナトリウム、ストロンチウムおよびアンモニウム塩をはじめとする、非金属および金属並びにアルカリ金属およびアルカリ土類金属の塩類が例示される。これらの塩類は単にカルボキシアルキルセルロースと、塩基たとえば、水酸化カリウムまたは水酸化アンモニウムとを反応させることにより形成することができる。
(1)酸化剤、燃料、バインダーおよび他の成分を、溶剤を使用しないでブレンドおよび/または摩砕し、粉末物質をプレスで圧縮する;
(2)セルロース系のバインダーを水性/有機溶液中で溶媒和し、燃料、酸化剤および他の添加物のような所望の成分を加え、プロペラント粒へ成型する。
その後、溶剤は乾燥除去される;
(3)セルロース系バインダーを溶媒和し、酸化剤、燃料および他の成分を加えて、ダイを通して加圧下にプロペラントを押し出し、様々な形状に成形する。その後、成型物は所定の長さに切断され、溶剤は蒸発されるか、加熱除去される。
Claims (7)
