摘要
通过极限氧指数和锥形量热分析研究了阻燃剂聚硼硅氧烷(BSi)对聚碳酸酯/丙烯腈-丁二烯-苯乙烯共聚物(PC/ABS)合金的阻燃作用。结果表明,添加5%(质量分数,下同)的BSi可使PC/ABS合金的极限氧指数从24%提高到28.6%;添加BSi可使火灾性能指数升高63%,并且可减少燃烧过程中产生的烟、热及CO、CO2等有害气体,促进成炭,保护基体材料,缓和燃烧过程,降低火灾安全隐患。
The effect of polyborosiloxane on the flame retardaney properties of PC/ABS alloy was evaluated using limited oxygen index and cone calorimeter analysis. When 5 wt % of polyborosiloxane was added, the limited oxygen index of PC/ABS alloy increased from 24 % to 28. 6 %, the fire performance index increased 63 %. The addition of polyborosilonaxe also decreased the total heat release and the emission of CO, CO2, and smoke during the combustion of PC/ABS alloy. The presence of polyborosiloxane promoted the formation of the char that protected the material matrix and moderated the combustion process.
