摘　　要： 应用动态力学分析仪，考察了玻璃微珠表面处理及其体积分数对ＰＰ／ＥＰＤＭ／玻璃微珠复合材料动态力学性能的影响。结果表明，ＰＰ／ＥＰＤＭ／用硅烷偶联剂ＣＰ０３作表面处理的玻璃微珠（Ｂ１）和ＰＰ／ＥＰＤＭ／未作表面处理的玻璃微珠（Ｂ２）复合材料的储能模量Ｅｃ′和损耗模量Ｅｃ″均随玻璃微珠体积分数φｇ的增大而呈非线性的增大；在相同条件下，ＰＰ／ＥＰＤＭ／Ｂ１复合材料的Ｅｃ′值大于ＰＰ／ＥＰＤＭ／Ｂ２复合材料，而两复合材料的Ｅｃ″值相近；随着φｇ的增大，ＰＰ／ＥＰＤＭ／Ｂ１复合材料的损耗因子ｔａｎδ减小，ＰＰ／ＥＰＤＭ／Ｂ２复合材料的ｔａｎδ增大；两复合材料的玻璃化转变温度Ｔｇ均呈不规则的变化。 The influence of the surface treatment and volume fraction of glass bead on the dynamic mechanical properties of PP/EPDM/glass bead composite was investigated by using a dynamic mechanical analyzer(DMA).The composites with two different glass beads were tested:one was surface treated with silane CP 03(B1) and the other was untreated(B2).The results showed that the storage modulus E c′ and the loss modulus E c″ of both the PP/EPDM/B1 composite and the PP/EPDM/B2 composite increased nonlinearly as the volume fraction φ g of glass bead increased;under the same conditions, E c′ of the PP/EPDM/B1 was higher than that of the PP/EPDM/B2,and their E c ″values were similar;the loss tangent tan δ of PP/EPDM/B1 decreased and tan δ of PP/EPDM/B2 increased as φ g increased;the glass transition temperature T g of both composites changed irregularly.
