초록

본 연구에서는 범용 열가소성 수지인 폴리프로필렌 (virgin polypropylene, VPP)과 폴리프로필렌을 주성분으로 하는 재생플라스틱의 난연성을 향상시키기 위하여, 난연제 decabromodiphenyl oxide (DBDPO)와 chlorinated paraffin wax (CPW)를 혼합하여 이것들의 난연 특성을 정량적으로 비교 분석 연구하였다. 난연성 평가 측정으로 콘 칼로리미터 (cone calorimeter, ASTM E1354, ISO 5660), 한계산소지수 측정 (LOI, ASTM D2863, ISO 4589) 등을 사용하였고, 콘 칼로리미터를 이용하여 DBDPO와 CPW의 난연효율을 정량적으로 측정하였다. 콘 칼로리미터의 결과로 난연제의 난연효율을 측정한 결과, DBDPO가 CPW보다는 약 2배의 난연효율을 가지고 있다는 것을 확인하였고, 한계산소지수 측정 결과와 유사한 난연효율을 보임을 확인하였다. 열중량 분석 (TGA) 측정결과 난연제 DBDPO를 첨가하였을 때 약 30~5$0^{\circ}C$의 열분해 온도의 상승을 확인할 수 있었다.

Fire resistance and thermal stability of polypropylene composite systems were investigated by using several halogenated fire-retardants such as decabromodiphenyl oxide (DBDPO) and chlorinated paraffin wax (CPW). The fire resistance of composite systems was thoroughly examined by measuring limited oxygen index (LOI, ASTM D2863, ISO 4589) and characteristic properties of cone calorimetry(ASTM E1354, ISO 5660) heat release rates (HRR), time to ignition (TTI), total heat release (THR), effective heat of combustion (EHC), mass loss rates, etc. Comparing the cone calorimetry experimental results of the halogen flame retardants, DBDPO exhibited twice higher efficiency than CPW in polypropylene systems, and the LOI also showed similar trends to cone calorimetry. The thermo-oxidative stability of the composite systems was increased about 30-5$0^{\circ}C$ in thermogravimetry analysis.Collectively, the combustion, extinction and thermally-stable characteristics of flame retardants were identified in this study.
