| 摘 要： | 利用毛细管流变仪研究了新型无卤阻燃剂对聚乳酸(PLA)流变性能的影响。结果表明:无卤阻燃剂对PLA起到了增塑作用,使PLA熔体的流动性能有所改善。当无卤阻燃剂用量为5%时,熔体非牛顿指数n趋近于1牛,顿性增加;熔体的黏流活化能△E和结构黏度指数△最小。

| Abstract: | The effects of novel non-halogen flame retardant on the rheological behavior of poly(latic acid) (PLA)in the process of melt-spinning by means of a capillary rheometer. The results indicate that the flame retardant has plasticizing effect on PLA and its fluidity is improved. As the content of flame retardant is 5%,non-newtonian index n approaches to 1,and the newtonian behaviour is improved. The viscous flow activation energy(△E ) and structure viscosity index (△ )of melt approach to minimum. |
