| 摘 要： | 研究了多芳基磷酸酯PX220与纳米蒙脱土复配阻燃剂对聚碳酸酯(PC)/丙烯腈-丁二烯-苯乙烯(ABS)合金的阻燃性能、热失重行为、力学性能及热变形温度的影响;并采用锥形量热仪对合金材料的燃烧性能进行测定。结果表明:PX220添加量为10份,纳米蒙脱土添加量2份时,PC/ABS合金的极限氧指数达到29%,燃烧性能达到UL 94V-0级。锥形量热仪分析结果表明:复配阻燃PC/ABS合金的热释放速率峰值、平均热释放速率、总释放热、平均有效燃烧热和平均质量损失速率都大幅下降,说明PX220与纳米蒙脱土具有非常好的协同阻燃作用。

| Abstract: | The effects of polyaryl phosphate ester and nano-MMT on the flame-retardant properties,thermo gravimetric behavior,mechanical properties and heat distortion temperature of PC/ABS alloy were studied.Cone calorimeter was employed to determine the flame-retardant properties of PC/ABS.The results showed that adding 10 phr phosphate and 2 phr nano-MMT into the alloy,the alloy′s oxygen index increased to 29%,and its combustion properties got UL 94V-0 grade.The result of cone calorimeter showed that the peak heat release rate,average heat release rate,total heat rate average effective combustion heat and average mass loss rate of PC/ABS were decreased which indicated the PX220 and nano-MMT had well synergistic flame retardant effect. |
