Abstract:

将聚硼硅氧烷(PB)阻燃剂分别与三种有机磷酸酯(OPP)阻燃剂进行复配,并将此复合阻燃剂添加到聚碳酸酯(PC)中制备了阻燃PC材料(FR-PC)。采用极限氧指数(LOI)和锥形量热分析研究了PB对OPP/PC体系的协同阻燃作用。结果表明:阻燃剂总质量分数为5%时,添加质量分数1.25%以上的PB可以提高OPP/PC体系的LOI;PB阻燃剂具有促进成炭的作用,可使OPP/PC复合体系在燃烧过程中释放的烟、热以及CO有不同程度的降低,燃烧过程趋于平缓,尤其使体系的烟释放量显著降低,三种OPP/PC阻燃体系的总烟释放量下降31.8%~51.0%,大大降低了火灾的危害性;添加适量PB能够提高OPP/PC体系的拉伸强度、弯曲强度及维卡软化点温度,并且使PC复合阻燃材料的透光率有所提高,保持了PC良好的透明性。
