요약
폼블럭은 셀프 인테리어 용품으로 새롭게 유행하고 있는 건축마감재로 폴리에틸렌을 주성분으로 하여 제조되고 있어 화재에 취약할 것으로 판단된다. 시중에 판매되고 있는 폼블럭 2종(일반, 난연)을 KS F ISO 5660-1(연소성능시험)의 기준에 따라 화재시 발생되는 연소특성을 파악하였다. 또한 적외선분광계(FTIR)를 이용하여 시편의 연소로 발생하는 가스중 대표적 독성가스를 측정한 후 기존의 독성모델에 적용하였다. 콘칼로리미터 시험 결과 2종의 시편 모두 복사열 차단장치를 제거하자마자 인화 및 불꽃연소가 시작되어, 화재시 화염의 급속한 전파 요인이 될 수 있음을 확인하였으며, 적외선분광계를 통한 연소가스 분석 결과, 일반적인 연소가스인 이산화탄소와 일산화탄소뿐만 아니라 인체에 심각한 위해를 주는 아크롤레인, 암모니아 및 시안화수소 등이 다량 검출되었다. 본 연구를 통해 폼블럭 제품은 착화성과 발열량이 높으며 유해가스가 다량 방출될 수 있음을 실험을 통해 확인하였다. 따라서 폼불럭 사용에 따른 재료의 연소특성, 즉 착화성 저감, 최대 열방출률 제한 및 주요 유해가스의 농도를 제한하는 기준마련도 시급히 요구된다.
Abstract
Foam block, popularized as the self-interior goods, is susceptible to fire since the main material is the polyethylene flammable synthetic resin. However, it is widely used in homes, offices, and multi-use facilities. In order to understand the fire characteristics of the foam block, two kinds of foam blocks sold in the market (non-fire retardant and fire retardant) were evaluated according to standard of KS F 5660-1 (Reaction to fire test). In addition, the hazard analysis of the gas generated by the combustion of the specimen was performed using the FTIR gas analyzer. The cone calorimeter test showed that the ignition and flame combustion of both two specimens were burned as soon as the radiant heat blocking device was removed, and it was confirmed that the flame could become a rapid propagation factor during the fire. The analysis of the combustion gas through the FTIR gas analyzer showed that both the carbon dioxide and carbon monoxide classified as the common combustion gases and the acrolein, ammonia, and hydrogen cyanide causing serious damage to the human body were detected substantially. This study showed that a foam block product has high ignitionability and generates toxic gases. Hence, it is urgently required to establish the standards used for properly classifying the combustion characteristics of the material on the basis of the use conditions of a foam block product and to prepare the standards on the purpose of use.
