| 摘 要： | 用双螺杆挤出机制备了丙烯酸(AA)改性三氧化二锑／聚丙烯(Sb2O3／PP)母料、十溴联苯醚(DBDPO)／PP母料及其相应的卤锑阻燃PP。研究了Sb2O3、DBDPO和卤锑阻燃剂阻燃PP的氧指数(LOI)。结果表明，Sb2％用量对PP的L01影响不大，而DBDPO使PP的L01明显提高，但Sb2O3与DBDPO有协同作用，可使DBDPO用量降低。然而，当阻燃剂质量分数高于5％，Sb2O3与DBDPO的协同作用降低。AA改性对PP的L01有影响，取决于AA的用量和引发剂的用量。

| Abstract: | The Sb_2O_3/PP masterbatch modified by acrylic acid (AA) with or without DCP and decabromodiphenyl oxide (DBDPO)/PP masterbatch were prepared by using a twin-screw extruder.The effect of Sb_2O_3,modified Sb_2O_3,DBDPO and modified Sb_2O_3/DBDPO on the limiting oxygen index ( LOI ) of the flame retarded PP was investigated. The results indicated that the LOI significantly increased by the addition of DBDPO,but Sb_2O_3 had little influence on the LOI of PP. For the same LOI ,the content of DBDPO decreased by the synergistic action of Sb_2O_3 and DBDPO. However,the synergistic action of Sb_2O_3 and DBDPO decreased as the mass fraction of the flame retardant was higher that 5%. The effect of AA on the LOI of the flame retarded PP depended upon the content of AA and DCP. |
