摘　　要：采用玻璃微珠改性两种基体性质显著不同的聚烯烃并对玻璃微珠的含量、粒径和复合材料加工方法对材料的加工流变行为进行了研究。结果表明 :加工方法、玻璃微珠含量和粒径对聚丙烯 /空心玻璃微珠 (PP/GB)复合材料的熔体流动速率和转矩流变性能的影响远大于对PE LLD/GB复合材料的影响 ,其中玻璃微珠含量的影响较粒径大。研究认为 ,无机刚性粒子填充改性热塑性聚合物时 ,加工方法、填料含量、几何特征等对复合材料流变特性是否发生影响 ,影响的程度等 。The rheological behaviors in processing of two composites, polypropylene/glass bead (PP/GB) and linear low density polyethylene/glass bead(PE-LLD/GB), were investigated. It was showed that the bead content, diameter and processing route possessed stronger effects on the PP/GB systems than on the PE-LLD/GB ones, with the effect of content of glass beads being the most remarkably. It was concluded that it was the nature of the matrix resin that determined the extent of the influence of the various parameters such as processing route, filler content, and filler geometry.
