요약

주거 건축 및 가구산업의 자재로써 합성목재(Wood-Plastic Composites)는 점차 각광받고 있다. 본 연구에서는 합성목재의 연소특성을 살펴보기 위하여 한계산소지수 측정(ASTM D 2863) 및 콘칼로리미터 시험(ISO 5660-1)을 실시하였으며 또한 일반목재인 적송과 방부 처리를 한 방부목에 대하여도 동일한 시험을 통하여 합성목재와의 연소특성을 비교.검토하였다. 한계산소지수 측정결과 합성목재가 적송 및 방부목에 비해 낮게 측정되었다. 콘칼로리미터 시험결과 합성목재의 열방출률이 가장 높았고 또한, 최대 열방출률 및 평균 열방출률, 총 방출열량도 적송 및 방부목에 비해 높게 나타났다.

Abstract

Wood-Plastic Composites (WPCs) are one of spotlighting materials for the residential construction and the industry for furniture. At this study, the limiting oxygen index (LOI) was measured by ASTM D 2863 and the cone calorimeter test was done by ISO 5660-1 to find the combustion characteristics of WPCs. In addition, the identical test was implemented to compare the combustion characteristics between the red pine and the antiseptic wood. The result of LOI measurement showed that the LOI of WPCs was lower than that of red pine or antiseptic wood. The cone calorimeter test showed that the heat release rate (HRR) of WPCs was the highest and the Peak HRR as well as the average HRR and total heat release of WPCs was higher than those of red pine or antiseptized wood
