摘　　要： 研究了稀土偶联剂 (REC)对PP/云母体系的流动性能、力学性能及老化性能的影响。未经处理的云母在填充量为 5 0 %时 ,冲击强度为PP的 70 % ,熔体质量流动速率 (MFR)低于 0 5g/10min ;而云母用质量分数为 2 5 %的REC处理后 ,填充量为 5 0 %的体系冲击强度接近PP ,MFR达 1 18g/10min。研究还表明 。 The effects of rare earth complex(REC) as a coupling agent on the flowability,mechanical properties and ageing property of PP/mica were investigated When the content of the untreated mica was 50%(mass fraction),the impact strength of the PP filled with the mica was 70% of that of pure PP and the MFR of the system was less than 0 5g/10min,while the PP filled with same loading of REC treated filler had almost same value of impact strength with pure PP and MFR of 1 18g/10min,which showed REC had obvious effect on the modification of mica,but no effect on the photo oxidation of the system
