This work intends to investigate the role of NaX zeolite nanoparticles as reservoir of Zn²⁺ and 2-mercaptobenzimidazole in prolonging the lifetime of an epoxy ester coating. Based on the XPS and SEM/EDX surface analysis and electrochemical data in solution phase, the synergistic inhibition effect of the organic and inorganic species released from the zeolite particles resulted in deposition of a dense protective layer mainly composed of zinc hydroxide, organic inhibitor and organic/inorganic complex on the surface. Accordingly, a synergistic corrosion protection was detected when the NaX zeolite particles doped with Zn²⁺/mercaptobenzimidazole were incorporated in the epoxy ester coating.

这项工作旨在研究NaX沸石纳米颗粒作为Zn ²⁺和2-巯基苯并咪唑的储库在延长环氧酯涂层寿命方面的作用。根据XPS和SEM / EDX表面分析以及溶液中的电化学数据，从沸石颗粒中释放出的有机和无机物类的协同抑制作用导致沉积了一层主要由氢氧化锌，有机抑制剂和有机物组成的致密保护层。 /表面上的无机复合物。因此，当将掺有Zn ²⁺ /巯基苯并咪唑的NaX沸石颗粒掺入环氧酯涂层中时，检测到协同腐蚀防护。
