초록

건축물에서 단열재는 매우 중요하다. 건축물에 사용하는 단열재는 재료에 따라 유기단열재와 무기단열재로 크게 나누는데 스티로폼이나 우레탄으로 만들어진 유기단열재는 화재에 매우 취약하다. 반면 펄라이트 무기단열재는 불연재이나 습기에 매우 취약하여 사용범위가 제한적이다. 본 연구에서는 단열성능이 보드의 두께가 50mm 이내의 샘플에서 열전도율과 흡수율은 각각 0.05W/mk, 3.0% 이하, 휨강도와 발수율은 각각 $25N/cm^2$, 98% 이상인 무기단열재를 개발하고 열전도 특성을 평가하였다.

The insulation in buildings is very important. Insulation used in the building is largely divided into organic and inorganic insulation by its insulation material. Organic insulations material which are made of styrofoam or polyurethane are extremely vulnerable to fire. On the other hand, inorganic insulation such as mineral-wool and glass-wool are very week with moisture while they are non-flammable so that its usage is very limited. In this study, inorganic heat insulating material developed and the properties of thermal conductivity evaluated. The thermal conductivity and the water absorption of the sample in less than 50mm thickness of the board is less than 0.05W/mk, 3.0%. Bending strength and the water repellency is more than $25N/cm^2$, 98%.
