요약
본 연구에서는 목분-HDPE 복합체를 모듈라 회전 이축압출기를 이용하여 제조하여 연소성 및 열적특성을 평가하기 위하여 콘칼로리미터 실험및 열중량 분석실험을 실시하였다. 그리고 복합체의 난연성능 향상을 위하여 난연제(3종)를 첨가한 복합체의 화재성능을 평가하였다. 콘칼로리미터 실험 결과 난연제를 첨가하지 않은 복합체의 열방출률이 가장 높았으며 최대 열방출률 값은 $446.6kW/m^2$, 평균 열방출률 값은 $185.5kW/m^2$으로 가장 높게 나타났다. 열중량 분석 결과 난연제 첨가한 복합체들의 열분해가 먼저 시작되고 열 안정성을 향상시켰다.
Abstract
In this study, we were manufactured wood flour-HDPE composites by modular co-rotating twin screw extruder with L/D ratio of 42. We was measured cone calorimeter test and thermogravimetric analysis (TGA) to find the combustion characteristics and thermal properties for wood flour-HDPE composites. We then evaluated the effect of three additive-type flame retardants on fire resistance performance. The cone calorimeter test showed that the heat release rate (HRR) of untreated composites was the highest Peak HRR ($446.6kW/m^2$) as well as Mean HRR ($185.5kW/m^2$). From the TGA, it was shown that composites added flame retardants began early thermal decomposition and improved thermal stability.
Key Words: Wood-plastic composites, Cone calorimeter, Heat release rate, TGA, Total heat release
