Abstract: 권취된 알루미늄 전해 캐피시터 소자에 전기전도도가 높은 전도성 고분자 용액을 함침하여 전도성 고분자 고체 전해 캐패시터를 제조하는 방법이 개시되어 있다. 본 발명에 따르면, 에틸알콜을 주성분으로 하는 1차 함침용액에 권취된 알루미늄 전해 캐패시터 소자를 침적시켜 함침한 후, 일정한 온도로 유지되는 건조로에서 건조하여 용매가 완전히 제거 되도록 한다. 이때, 함침은 상온 상압 뿐만 아니라 고온 감압하에서도 우수한 함침특성을 나타낸다. 건조 처리된 소자를 다시 에틸알콜을 주성분으로 하는 2차 함참용액에 함침 한 후 일정한 온도로 유지되는 건조로에서 건조하여 전도성 고분자를 형성 시킨다. 이렇게 전도성 고분자가 중합된 소자를 알루미늄 캔에 삽입하고 라버로 밀봉 건조시킴으로써 전도성 고분자 고체전해 캐패시터를 얻을 수 있다. 이렇게 제조된 전도성 고분자 고체 전해 캐패시터는 2차 함침에 의해 함침효과가 우수하여 고용량, 저 임피던스 및 낮은 등가 직렬저항(ESR) 값을 가지며,  고신뢰성의 제품 특성을 나타낸다.

Title: Organophosphorus compound having phosphate-phosphonate bond, and flame-retardant polyester fiber and flame-retardant polyurethane resin composition each containing the same
Inventor: HIRATA MANABU
IPC: C09K21/12
Filed: 2004-06-04
Abstract: A phosphate-phosphonate compound which is lowly volatile, has a high phosphorus content, and does not influence various properties of a product when used as a material therefor. It is reduced in environmental burden in view of suitability for recycling and contains no halogen atoms including chlorine and bromine. The phosphorus compound has a phosphate- phosphonate bond within the molecule and has a specific ring structure. Because of this, the compound has excellent flame retardancy. Addition of the phosphate-phosphonate compound as a flame retardant for polyurethanes or polyesters imparts satisfactory plasticity and flame retardancy. The flame retardant is reduced in the exertion of adverse influences on the material properties of, in particular, polyurethane foams, polyester fibers, and the like.
