利用水热法合成了碟状 α-磷酸锆（ α-ZrP）并以此为功能填料制备了新型防腐聚酯粉末涂料，采用 SEM、FT-IR和 XRD对磷酸锆的物理形貌和化，学结构进行了表征，分别运用 TGA-DTG和 SEM分析了防腐涂料涂层的热稳定性与微观形貌。以 3.5%NaCl水溶液模仿海洋环境，测试了不同 α-ZrP含量的聚酯粉末涂层在浸泡过程中的交流阻抗谱（ EIS）和极化曲线（ LSV）分析了 α-ZrP对涂料防腐性能的影响。结果表明：添加碟状 α-ZrP能够大幅增强聚酯涂层的耐腐蚀能力，腐，蚀电压显著正移，腐蚀电流密度下降 1~3个数量级。当 α-ZrP的含量占总组分的 3%时，涂层的防腐性能达到最佳。
Disc-like α-zirconium phosphate（α-ZrP）was synthesized using hydrothermal method and used as a functional filler to prepare the novel polyester powder anti-corrosion coatings. The physical morphology and chemical structure of zirconium phosphate were characterized by using SEM，FT-IR and XRD. The thermal stability and micromorphology ofthe anticorrosion coatings were investigated using TG-DTG and SEM respectively. The impedance spectra（EIS） and polarization curves（LSV） of polyester powder coatings with different content of α-ZrP were tested in a 3.5wt.%NaCl aqueous solutionto simulate the marine environment for different time. The effect of α-ZrP on corrosion resistance of polyester powder coatings was analyzed. The results showed that addition of α-ZrP could significantly improve the anticorrosion performance of the polyester coatings with a reduction of corrosion current density by 1~3 orders of magnitude compared with the pure polyester coatings，and the corrosion voltage of the coatings also shifted positively. When the content of α-ZrP was 3% of the total composition，the coatings provided the best corrosion resistance.
