摘　　要：采用熔融共混法制备出了高密度聚乙烯（HDPE）／纳米碳酸钙（nano—CaCO3）复合材料。研究了nano-Ca—CO3的加入量对复合材料力学性能的影响，利用扫描电镜（SEM）分析了nano-CaCO3在HDPE基体中的分散性。结果表明，随着nano—CaCO3用量的增加，HDPE／nano-CaCO3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，而弯曲模量呈增加趋势；随着用量的增加，nano-CaCO3在HDPE基体中的分散性逐渐变差。HDPE/nano-CaCO3 composite was prepared by melt blending. The effect of the nano-CaCO3 content on mechanical property of the HDPE/nano-CaCO3 composite was studied. The dispersion of the nano- CaCO3 in HDPE matrix was analyzed by SEM. The results showed that the impact strength and tensile strength of the HDPE/nano-CaCO3 composite both increased with the nano-CaCO3 content, and then de- creased with the nano-CaCO3 content, but the flexural modulus of the HDPE/nano-CaCO 3 composite evident- ly increased with the nano-CaCO3 content. The dispersion of the nano-CaCO 3 in HDPE matrix gradually became bad.
