초록
본 연구는 새로 개발된 난연도료를 바탕재(FRP PVC, AL, 스테인레스 스틸)에 도장한 실험체에 대하여 난연성. 화염전파. 산소지수. 가연성, 연기밀도, 독성지수를 평가하였다 연구결과 실험체(AL, 스테인레스 스틸)의 난연1급실험은 적합하였으며, 실험체(FRP, AL, 스테인레스 스틸)의 화염전파실험에서 착화되지 않았고, 실험체 모두의 산소지수는 약 $50\%$, 가연성실험은 V-0급으로 나타났다. 또한 연기밀도 챔버를 이용한 Flaming mode에서 최대연기밀도는 43-338 및 덕성지수는 0.57-1.12인 것으로 나타났다.
In this paper, The experimental materials of painted fire resistant paint on substrate, FRP, PVC, AL and stainless steel that fire resistant paint developed newly were evaluated as the hazard elements : the fire resistibility of the materials, fire spread test of flame, the oxygen index, flammability, the smoke density. the toxicity index from it when it burned. As a result of the experiments, the AL and the stainless steel were passed of fire resistant class 1, the FRP, the AL, and the stainless steel were ignited of fire spread test of flame, all the experimental materials showed about $50\%$ of oxygen index, V-0 of flammability, and 43-338 of maximum smoke density at flaming mode used smoke density chamber. Also, they showed that the toxicity index of combustion products were 0.57-1.12.
