摘　　要：采用钛酸酯偶联剂改性纳米ZnO,改善其在涂料中的分散性,通过红外、SEM分析证明改性效果理想。然后将改性后的纳米ZnO以不同的添加量(分别为0.05%、0.5%、1%、2%质量比)加入丙烯酸聚氨酯涂料中,将此4种涂层分别进行EIS测试与分析,并结合其耐盐水表面形貌分析得出0.5%含量的改性纳米复合涂层具有最好的防腐效果,其涂层防腐性明显优于其他3种涂层。Modifying nano-ZnO by titanate coupling agent, and testing the result of modification by IR spectrum and SEM, it is showed that the dispersion property of nano-ZnO has been improved through modification. The modified nano-ZnO is added into the acrylic PU coatings. EIS is used to test the four films respectively with the nano-ZnO amount of 0.05%, 0.5%, 1% and 2%. Salt water resistance surface morphology analysis shows that, with the nano-ZnO amount of 0.5%, the film is of best anticorrosion property, far more than other three films.
