요약
무기재로서 질석은 친환경적인 특성과 내화, 단열, 흡음 뿐 만 아니라 결로방지, 탈취 및 미관 등이 우수하므로 건축마감재로서 활용될 경우 효용성이 높을 것으로 판단된다. 본 연구에서는 질석을 주원료로 하여 미네랄 루즈울(Mineral Loose Wool) 또는 미네랄 파우더(Mineral Powder)를 혼입한 건축용 마감보드를 개발하고 불연시험과 단열시험을 수행하였다. 시험결과 두 개의 질석보드 모두 불연재로서 성능을 확보하였으며 열전도율 0.086 및 $0.092W/m{cdot}K$로 나타났다. 또한 개발된 두 개의 질석보드를 경골목구조 내화벽체 표준상세(KS F 1611-1)의 마감재로 적용하여 내화시험을 수행하였다. 내화시험결과 VB-L 시험체가 VB-P시험체 보다 내화성능이 다소 높게 나타났으며 두 개의 질석보드 모두 두께 30 mm로도 내화성능 2시간 확보가 충분한 것으로 나타났다.
Abstract
It is considered that vermiculite as an inorganic material is highly effective when it is used as a building finishing material because it is eco-friendly. Vermiculite has excellent properties such as fire resistance, heat insulation, sound absorption as well as prevention of condensation, deodorization and aesthetics. In this study, we developed a finishing board with vermiculite as its main material and mixed with mineral loose wool (VB-L) or mineral powder (VB-P), and conducted fireproof test and insulation test. In addition, fire resistance tests were carried out by applying the two developed vermiculite boards as finishing materials for the standard wall details of light frame wood structures (KS F 1611-1). As a result of the fire resistance test, the VB-L specimen showed better fire resistance than the VB-P specimen. Both vermiculite boards showed sufficient fire resistance performance of 2 hours for a thickness of 30 mm.
Key Words: Vermiculite Board, Mineral Loose Wool, Light Frame Wood Structures, Fire Resistance Test
