| 摘 要： | 采用毛细管流变仪研究无卤阻燃聚碳酸酯/丙烯晴-丁二烯-苯乙烯共聚物（PC/ABS）的流变行为，得到了熔体表观黏度及切应力与剪切速率的关系。结果表明，无卤阻燃PC/ABS合金熔体为假塑性流体，表观黏度随剪切速率的增加而降低；在230 ℃时，合金的非牛顿指数随着阻燃剂含量的增加而增加；在剪切速率为20~3000 s-1时，合金黏度对温度不敏感，即实现黏度降低，采用升温法效果不佳。

| Abstract: | Rheological behavior of non-halogen flame-retarded PC/ABS alloy was studied, the relationship of melt apparent viscosity and shear stress/shear rate was found. It showed that this system was non-Newtonian pseudo plastic fluid and the apparent viscosity of the melt decreased with the increase of shear rate. At the temperature of 230 ℃, non-Newtonian index of the alloy increased with increasing content of the flame-retardant. When the shear rate was 200-3000s-1, the viscosity value of the alloy was not sensitive to temperature. |
