Effect of Flame Retardants on Flame Retardancy of Rigid Polyurethane Foam

Abstract

본 연구에서는 인계 난연제가 첨가된 경질 폴리우레탄 폼을 합성하여 난연제의 종류에 따른 난연성능 변화를 고찰하였다. 난연제로는 Tetramethylene bis(orthophosphorylurea) [TBPU]와 Tris(2-chloroethyl)phosphate[TCEP], Tris(2-chloropropyl)phosphate[TCPP], Triethyl phosphate[TEP]등을 사용하였다. 콘칼로리미터를 이용하여 열방출량, 질량감소율, 연기발생량, CO 및 $CO_2$ 발생량 등을 측정하였다. 콘칼로리미터 시험 결과 TBPU가 첨가될 경우 평균 발열량, 최대 발열량, 유효연소열, 질량 감소율, CO 및 $CO_2$ 발생량이 감소하였고 다른 난연제에 비하여 낮은 값을 나타내어 우수한 난연성능을 나타냄을 알 수 있었다. In this study, the effect of phosphorus flame retardants on the flame retardancy of the rigid polyurethane foam(PUF) was studied. Tetramethylene bis(orthophos-phorylurea)[TBPU] and Tris(2-chloroethyl) phosphate[TCEP], Tris(2-chloropropyl)phosphate [TCPP], Triethyl phosphate[TEP] were used as flame retardant. It was found that TBPU added PUF exhibits low mean heat release rate(HRR), peak HRR, effective heat of combusion(EHC), mass loss rate (MLR), CO yield and $CO_2$ compared other flame retardants.
