초록
본(本) 연구(硏究)는 기능성(機能性) elastomer 개발(開發)의 일환(一環)으로서 1-chlorobutadiene-butadiene copolymer(CB-BR)의 수가교(水架橋)에 의(依)한 기능성(機能性)의 향상(向上)에 그 목적(目的)을 두었으며 가교제(架橋劑)로서 3-aminopropyltriethoxysilane을 이용(利用)하여 CB-BR의 활성염소(活性鹽素)와의 용액반응(溶液反應)을 속도론적(速度論的)으로 해석(解析)하였다. 그리고 APS와 CB-BR을 실제공정(實際工程)에서 배합(配合)하여 수중가교반응(水中架橋反應)을 진행(進行)시켜 이에 따른 물성(物性) 검토(檢討)를 하므로써 다음과 같은 결론(結論)을 얻었다. 1. CB-BR은 용액계(溶液系)에서 APS와 용이(容易)하게 반응(反應)하며 이때의 반응(反應) 속도상수(速度常數) 및 활성화(活性化)에너지는 다음과 같다. 2. CB-BR+APS 수가교체(水架橋體)의 최적(最適) press 조건(條件)은
In this study, as one of the developing ways of the functional elastomer, improvement of the functionality of CB-BR was attempted through moisture curing reaction. The curing reaction of CB-BR was determined with an use of 3-aminopropyltriethoxysilane(APS) as a crosslinking agent, also a solution reaction with an active chlorine of CB-BR was elucidated by using a reaction kinetics theory and a study of physical property was made through moisture curing on the compound of 3-aminopropyltriethoxysilane and CB-BR The results of this study obtained are as follows : 1) CB-BR reacted easily with APS in the liquid state and the reaction rate coefficient and activation energy were as follows : 2) Optimum pressure condition of moisture cured elastomer(CB-BR+APS) was 20 minutes at
