| 摘 要： | 结合碱式硫酸镁晶须（MOS）的补强和阻燃功能，以微胶囊红磷（MRP）为协效剂，制备了无卤阻燃型PP（聚丙烯）／EPDM（三元乙丙橡胶）／MOS／MRP共混物，并与PP／EPDM／Mg（OH）2／MRP共混物进行比较。氧指数（LOI）及垂直燃烧（UL-94）测试表明MOS的阻燃效果优于Mg（OH）2。力学性能测试表明，MOS对PP／EPDM热塑性雌性体具有一定的增强作用，PP／EPDM／MOS／MRP阻燃体系的力学性能明显优于PP／EPDM／／MRP阻燃体系。而PP／EPDM热塑性弹性体的动态硫化进一步提高了PP／EPDM／MOS／MRP阻燃体系的力学与阻燃性能。

| Abstract: | Considering the reinforcement and flame retardant function of basic magnesium sulfated whisker(MOS),the PP/EPDM/MOS/MRP composites were prepared,and were compared with PP/EPDM/Mg(OH)_2/MRP composites.The results from limiting oxygen index(LOI) and vertical combustion(UL-94) tests showed that the flame retardant efficiency of MOS was higher than that of Mg(OH)_2. The mechanical properties test showed that PP/EPDM was reinforced by MOS.The mechanical properties of PP/EPDM/MOS/MRP composites were higher in comparison with PP/EPDM/Mg(OH)_2/MRP composites.The mechanical,processing and flame retardant properties of PP/EPDM/MOS/MRP composites were improved by the dynamic vulcanization of PP/EPDM. |
