본 연구는 주택이나 창고 등의 건축용 합성 단열재의 연소특성을 분석한 것으로 콘칼로리미터 및 SEM을 활용해 난연 스티로폼, 일반 스티로폼, 우레탄, 석고보드 등 4종의 재료별 연소특성을 실험 및 분석하였다. 시험결과 각 재료별 착화특성으로는 상기 단열재에 대한 착화시간(TTI)은 27 s~43 s로 나타났으며, 이중 난연 스티로폼은 TTI이 가장 낮은 27 s에 착화되었다가 28 s에 소멸됨을 보였다. 또한 각 재료들의 최대열방출율(peak HRR)과 평균열방출율(mean HRR)의 크기는 우레탄>석고보드>난연 스티로폼>일반 스티로폼으로 나타났으며, 총열방출량(Total Heat Release Rate, THR)은 우레탄>난연 스티로폼>일반 스티로폼>석고보드 순으로 나타났다. 또한 총연기방출량(Total smoke release, $m^2/m^2$)은 난연 스티로폼에서 가장 많은 $30.798m^2/m^2$을 보였다. 일반 스티로폼의 CO 방출농도는 0.275 kg/kg, $CO_2$ 방출농도는 12.807 kg/kg값이 나타났다. 잔유물은 위 4가지 재료 중 석고보드에서 가장 많은 0.029 g을 보였다.
This study is an analysis of combustion characteristics of synthetic insulation materials such as houses and warehouses. Using combustion cone calorimeter and SEM, the researching has experimented combustion characteristics of four kinds of materials such as flame retardant styrofoam, general styrofoam, urethane and gypsum board. And analyzed. As a result of the test, the ignition time (TTI) for the thermal insulation material was found at 27 s~43 s, and the flame retardant styrofoam was ignited at the lowest TTI at 27 s and disappears at 28 s. In addition, the maximum heat release rate (peak HRR) and average heat release rate (mean HRR) of each material were expressed in the following order: urethane> flame retardant styrofoam> styrofoam> gypsum board. Also, the total smoke release ($m^2/m^2$) was the largest at $30.798m^2/m^2$ in flame-retardant styrofoam. The general CO concentration of styrofoam was 0.275 kg/kg and the emission concentration was 12.807 kg/kg. The residues showed the highest 0.029 g in the gypsum board among the above materials.
