摘　　要：采用熔融共混法制备出了聚丙烯(PP)/纳米碳酸钙(nano-CaCO3)/三元乙丙橡胶(EPDM)复合材料。分别研究了nano-CaCO3和EPDM的加入量对复合材料力学性能的影响。结果表明:随着nano-CaCO3用量的增加,复合材料的冲击强度和拉伸强度均呈现出先增加后降低的趋势,弯曲模量呈增加趋势;随着EPDM用量的增加,复合材料的冲击强度呈增加趋势,拉伸强度和弯曲模量均呈下降趋势。PP/nano-CaCO3/EPDM composite was prepared by melt blending. The effect of the nano-CaCO3 amount and EPDM amount on mechanical property of the PP/nano-CaCO3/EPDM composite were respectively studied. The results showed that the impact strength and tensile strength of the PP/ nano-CaCO3/EPDM composite both increased with the nano-CaCO3 content, and then decreased with the nano-CaCO 3 content, and the flexural modulus of the composite increased with the nano-CaCO3 content. The impact strength of the PP/nano-CaCO3/EPDM composite increased with the EPDM content, and the tensile strength and flexural modulus of the PP/nano-CaCO3/EPDM composite both decreased with the EPDM content.
