Abstract

The fire resistive materials are used to resist from fire accidents in the building. In this study silicone rubber/inorganic flame retardant composites were prepared by mechanical stirring method, using aluminium trihydroxide(ATH, $Al(OH)_3$) and magnesium dihydroxide(MDH, $Mg(OH)_2$) as synergistic fire-resistant additives. The thermal properties of the fire resistant composites were characterized by thermogravimetric analysis(TGA). In addition, rheological properties were observed by rheometer and fire-resistant properties were tested by gas torch. Through this study, we realized that the silicone rubber containing ATH, MDH increased the performance of fire-resistance.

내화재료는 건축물에서 화재사고로부터 화염을 차단하기 위해 사용된다. 본 연구에서는 실리콘 고무에 무기계 난연제인 aluminium trihydroxide(ATH, $Al(OH)_3$)와 magnesium dihydroxide(MDH, $Mg(OH)_2$)를 첨가한 복합체를 기계적 교반으로 제조한 후 내화성능향상에 관한 연구를 진행하였다. 내화재료의 열 특성분석을 위해 TGA를 사용하였고, rheometer를 이용해 유변학적 분석을 하였다. 내화특성을 분석하기 위해 gas torch를 이용하였다. 본 연구를 통하여 ATH와 MDH가 첨가되면 실리콘 고무의 내화성능이 향상됨을 알 수 있었다.
