EPS Bead와 유리섬유를 혼입한 샌드위치 패널 심재의 단열 특성 = Thermal Insulation Properties of Sandwich Panel Core with EPS Bead and Glass Wool

다국어 초록 (Multilingual Abstract)

To improve the fire vulnerability of the organic insulation sandwich panel core, which is the main culprit of the large-scale fire disaster, an experiment was conducted to examine the thermal conductivity properties of the core material mixed with the organic insulation material EPS Bead and the inorganic insulation material glass wool. As the Additional ratio of glass wool increased, the thermal conductivity decreased, and it was determined that the replacement of glass wool of 3% or more had little effect on the decrease in thermal conductivity. In addition, it can be seen that the most ideal thermal conductivity is exhibited when 1% Replacement ratio of EPS and 3% glass wool are added. The core material of such organic and inorganic insulation materials is judged to be a core material that can compensate for the fire vulnerability of existing insulation materials. Therefore, in order to determine whether it is used as a core material for sandwich panels, additional studies such as fire resistance experiments and sound absorption experiments are needed in the future.
