Abstract

Curing reaction for butyl rubber complexes applicable to a tire bladder is investigated as a function of the degree of unsaturation (DU). High molecular weight butyl rubbers with various DU were synthesized by cationic polymerization, providing three butyl rubbers between 1.8 and 8.4 mol% of DU. Dynamic mechanical measurement and swelling test were conducted for the systematic study of curing rate, curing density, aging, and curing mechanism. Our findings shed new light on technologically important butyl rubber-based materials.


본 연구에서는 부틸고무의 불포화도에 따른 블래더용 부틸고무 복합체의 가교 반응 속도를 연구하였다. 양이온 중합법을 이용하여 다양한 고불포화도를 갖는 고분자량 부틸고무를 합성하였다. 상용 부틸고무는 2 mol% 내외의 불포화도를 포함하고 있지만, 본 연구에서는 불포화도를 8.4 mol%까지 변화시킴으로써, 부틸고무 시스템에서 불포화도에 따른 가교 속도, 가교 밀도, 노화 및 가교 메커니즘에 대해 체계적으로 연구하였다. 본 연구는 부틸고무를 사용하는 블래더를 포함한 다양한 제품 생산의 품질 향상과 공정조건 최적화에 활용될 수 있다.
