摘　　要：采用熔融共混法制备聚丙烯(PP)/云母复合材料,用湿热老化箱研究了PP/云母复合材料湿热老化性能。结果表明:PP/云母复合材料强度和刚度随云母含量增加而较大幅度增加;云母使复合材料的抗湿热老化效果显著。但随着云母含量的增加,抗湿热老化效果下降,云母质量分数为10%时,效果最佳。Polypropylene（PP）/mica composites were prepared by melt method, the hygrothermal aging properties of the composites were studied by aging box. The results show that the strength and stiffness of PP/mica composites increase greatly with the in- creasing of mica content, mica in matrix improves the resistance to hygrothermal aging. But the resistance decreases with the increasing of mica content, when the mass ratio of mica is 10%, the resistance is best.
