摘　　要：研究比较了纳米TiO2、纳米ZnO、纳米SiO2对石油沥青双组分聚氨酯防水涂料性能的影响。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, nann-ZnO and nano-SiO2 on performance of self-made petroleum asphah polyurelhane water-proof coating was studied. The results showed that the nano-particles can improve remarkably weather-resistanee and acidproof properties of the painting membrane,and enbance its hardness,tensile strength and uhimate elongation. The weather-resistance property of the painting membrane increases in the following order：nano-SiO2〈nano-ZnO〈nano-TiO2. Hardness,tensile strength and ultimate elongation of.the painting membrane increases in the following order： nano-TiO2〈nano-ZnO〈nano-SiO2. Optimum dosages of nann-particles are 3.0%-5.0% based on total mass of all materials added.
