摘　　要：研究了有机硅改性剂对聚丙烯(Polypropylene,PP)和氢氧化镁(Magnesium Hydroxide,MH)复合材料的微观结构以及熔融流动性能和燃烧性能的影响。结果表明:在PP/MH复合体系中加入适量有机硅改性剂后,MH粒子的团聚程度显著降低,复合材料的微观组成更加均匀,熔融流动性能更好,水平燃烧级别下降,但对材料的氧指数影响不大。The influence of organosilieone on the structure and properties of PP/MH composites was investigated. It was found that the introduction of a certain amount of organosilicone could reduce the agglomeration of MH particles noticeably and make the composition of the composites more homogeneous. In addition,the flowability of the composites was greatly enhanced and the levels of horizontal and vertical burning declined, but it had no appreciable influence on the oxygen index.
