摘　　要：在PP/PA6基体中分别添加两种无机纳米粒子(SiO2,TiO2)和5%的接枝POE作为相容剂。采用三种不同的共混工艺制备PP/PA6/纳米粒子复合材料,并对其性能进行了对比分析。通过力学性能测试和SEM照片观测分析了影响复合材料力学性能的因素。结果表明:分步法的制备工艺能够明显提高PP/纳米粒子复合材料的综合力学性能,改善分散相的相容性。并且研究发现:在PP/PA6中添加相同质量分数的纳米TiO2的综合力学性能要优于纳米SiO2。Inorganic nano-partieles （SiO2,TiO2 ） and 5 % grafted POE as compatibilizer were used to PP/PA6. PP/PA6/ nano-partieles composites were prepared by three different blending technologies and comparative analysis their properties. The results showed that the comprehensive mechanical properties and the compatibility of the dispersed phases of PP/nano-particles composites could be improved evidently by fractional step method. Also it showed that the mechanical properties of adding the same mass fraetion nano-TiO2 were better than the nano-SiO2 into PP/PA6.
