Abstract
Inorganic fillers have attracted a great deal of interest as reinforcing materials for fire-proof performance in silicone rubber (SR). In this study, magnesium hydroxide (MDH) and aluminium hydroxide (ATH)/SR composites, well known fire-proof materials, and mineral wool/SR composites were analyzed for thermal and physical properties. It was confirmed that mineral wool/SR composites have an improved fire-proof performance than the (MDH, ATH)/SR composites through gas torch flame test, cone calorimeter, and thermogravimetric analysis (TGA). MDH/SR shows great tensile, tear strength and elongation at break through SEM and UTM due to the fine dispersion of MDH in SR. Also, mineral wool/SR composites show compressive strength and hardness properties higher than those of (MDH, ATH)/SR composites.

무기계 내화 필러는 실리콘 고무의 내화 성능 보강재로서 많은 관심을 받고 있다. 본 연구에서는 실리콘 고무 내화 필러로서 잘 알려진 수산화마그네슘(MDH), 수산화알루미늄(ATH)과 미네랄 울 2종의 실리콘 복합체를 제작해 열적, 물리적 특성을 비교 분석하였다. 가스토치 화염시험, 콘칼로리미터, TGA 분석을 통해 미네랄 울 2종의 내화 성능이 기존의 내화 필러 복합체보다 우수함을 확인하였다. 주사전자현미경(SEM), 만능재료시험기(UTM)를 통해 필러의 표면적이 큰 MDH를 실리콘 고무에 효과적으로 분산시킨 MDH/실리콘 고무 복합체가 인장, 인열, 신장율에서 우수한 특성을 나타냈고, 미네랄 울/실리콘 고무 복합체는 (MDH, ATH)/실리콘 고무 복합체에 비해 압축 강도, 경도에서 우수한 특성을 확인하였다.
