摘　　要：用纳米氧化锌(ZnO)与聚丙烯(PP)通过熔融共挤制得了ZnO/PP纳米复合材料,研究了ZnO/PP纳米复合材料的力学、流变学性能与纳米ZnO添加量之间的关系;同时制备了ZnO/CaCO3/PP三元纳米复合材料并对其进行了机械性能和制备成本分析。结果表明:ZnO/PP纳米复合材料的力学性能随纳米ZnO添加量的增加表现出冲击韧性先升后降,拉伸强度变化不敏感的特点;纳米CaCO3的加入不但可以降低生产成本,而且可以显著改善体系的冲击韧性;材料的拉伸破坏属于韧性断裂过程。ZnO / PP nano composite was obtained by fusion coextrusion of nano- ZnO and PP. research on the relationship between ZnO / PP nanocomposite mechanical, rheological properties and ZnO additionals; at the same time, prepared ZnO/CaCO3/PP ternary nano-composite materials and their mechanical properties and the preparation cost analysis. The results shows that： ZnO / PP nanocomposite mechanical properties changes with ZnO additionals increasing. The fact is toughness first raised and then decreased and tensile strength is not sensitive; To add nano-CaCO3 accession not only reduce production costs, but also significantly improve the impact toughness; destruction of the tensile belongs to toughness fracture process.
