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.

• 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。
