Assessment of Flame Retardancy for Acrylonitrile Butadiene Styrene Containing Metal Powder and Flame Retardant
Song Young-Ho, Chung Kook-Sam
고분자 물질의 화재 위험성 및 화재시 인명 피해의 감소를 위한 기초자료로 제시하고자 난연제 및 금속분말의 첨가에 의한 난연성 평가를 수행하였다. 본 연구를 위하여 중량감소율,한계산소지수 및 탄화층 생성량 측정, 연기 중량 농도 및 일산화탄소 발생량 측정의 실험을 수행하였다. 금속분말과 난연제를 함유한 acrylonitrile butadiene styrene은 낮은 중량감소율을 나타내었고, 한계산소지수 및 탄화충 생성량은 증가하였으며, 연기 중량 농도 및 일산화탄소의 발생량도 감소하는 결과를 나타내었다. 또한 가장 효과적인 복합체는 tricresyl phosphate-Mo 복합체로 나타났다.
The flame retardancies by the addition of metal powder and flame retardant were evaluated to present as the fundamental data to decrease the fire hazard of polymers and life losses by suffocation and poisoning. For this study, the experiments of flame retardancy were conducted as follows : weight loss rate using thermogravimetric analysis, the measurement of the limiting oxygen index(LOI) and char yield. And smoke mass concentration and CO yield were measured. Acrylonitrile butadiene styrene containing metal powder and flame retardant reduced weight loss rate and increased LOI and char yield with the decreased smoke mass concentration and CO yield. It was found that the most effective complex was tricresyl phosphate-Mo complex.
Key Words: Flame retardant, LOI, Char yield, Smoke mass concentration
