摘　　要：研究比较了纳米TiO2、纳米ZnO、纳米SiO2对自制的石油沥青双组分聚氨酯涂膜性能的影响。结果表明,纳米粒子的添加可显著地改善涂膜的耐候性能、耐酸性能,提高涂膜的硬度、抗张强度和断裂伸长率;对涂膜耐候性改善程度依次为纳米TiO2>纳米ZnO>纳米SiO2,而对涂膜硬度、抗张强度、断裂伸长率提高程度依次为纳米SiO2>纳米ZnO>纳米TiO2;纳米粒子较佳的添加量为物料总质量的3%～5%。The influence of nano-TiO2,nano-ZnO and nano-SiO2 on performance of self-made petroleum asphalt polyurelhane water-proof coating was studied.The results showed that the nano-particles can enhance hardness and tensile strength and ultimate elongation of the painting membrane（PM）,and can improve remarkably weather-resistance and acid-proof properties of the PM.The weather-resistance property of the PM increases in the following order：nano-SiO2nano-ZnOnano-TiO2.Hardness and tensile strength and ultimate elongation of the PM increase in the following order：nano-TiO2nano-ZnOnano-SiO2.Optimum dosages of nano-particles are 3.0%～5.0% based on total mass of all materials added.
