Abstract

EPS sandwich panel contains flame retardants that slow down ignition during fires,reduce the amount of heat generated, and block the spread of combustion. However, if a sandwich panel does not satisfy standards for fire-retardant performance, it may increase damage to property and human life. It is difficult to test the fire-retardant performance of a finishing material with the naked eye, so it is necessary to develop convenient and fast evaluation methods that are convenient and fast. In this study, a fire safety evaluation method for EPS sandwich panel was analyzed using X-ray to detect specific components related to the fire-retardant performance X-ray fluorescence analysis (XRF) indicated that suitable panel products contained more aluminum in comparison to unsuitable products. Gibbsite was identified as the main crystalline material of flame retardant EPS through X-ray diffraction analysis (XRD) and was included in both suitable products and unsuitable products, but there was a difference in crystalline structure. This study was verifies the possibility of evaluating fire-retardant performance using ultimate analysis and crystal analysis through these X-ray methods.

EPS 샌드위치 패널은 난연제의 첨가로 화재 시 발화를 늦춰주며 발열을 적게 발생시켜 연소의 확대를 막는다. 하지만 난연성능 기준에 미달하는 샌드위치 패널을 사용할 경우, 재산 및 인명 피해가 확대되는 사례가 발생할 수 있다. 마감재료의 난연성능은 육안으로는 확인이 어려워 간편하면서도 빠른 평가방법의 개발이 요구된다. 본 연구에서는 X-선 분석법(XRF, XRD)을 이용하여 EPS 샌드위치 패널의 화재안전평가 방법에 대해 분석하였다. X-선 분석법을 적용한 결과 화재시험을 통한 난연 성능에 따라 특정 성분이 검출되는 것을 확인하였다. X-선 형광분석(XRF)을 통해 알루미늄성분이 부적합제품에 비해 적합제품에 훨씬 많이 함유되어있는 것을 알 수 있었다. X-선 회절분석(XRD)을 통해 난연 EPS의 주된 결정성 물질로 확인된 깁사이트(gibbsite)는 적합제품과 부적합제품에 공통으로 함유되어 있었지만 결정성에 있어 차이가 나는 것을 확인하였다. 이러한 X-선 분석을 통한 원소분석과 결정분석으로 난연성능 평가 가능성을 확인하였다.
