Two triazine derivatives were synthesized and characterized by HR-MS and ¹H NMR spectroscopy. Melamine (S₁), S₂ and S₃ were examined as corrosion inhibitors for medium carbon steel in 1 M HCl solution using electrochemical measurement, weight loss and surface analysis. The theoretical studies combining with experimental results revealed a same inhibition order S₃ > S₂ > S₁. This study proved that the synergistic effect of surface active functional groups and corrosion inhibition functional groups on corrosion inhibition performance and sufficiently comprehensive and detailed to explain the effects and mechanism of triazine inhibitors.

具有表面活性的三嗪衍生物作为酸性介质中碳钢的有效缓蚀剂的合成，实验和理论研究

合成了两种三嗪衍生物，并通过HR-MS和¹ H NMR光谱进行了表征。使用电化学测量，重量损失和表面分析，研究了三聚氰胺（S ₁），S ₂和S ₃作为中碳钢在1 M HCl溶液中的腐蚀抑制剂。理论研究与实验结果相结合，揭示出相同的抑制顺序S ₃  > S ₂  > S ₁。该研究证明了表面活性官能团和缓蚀官能团对缓蚀性能的协同作用，并充分全面详细地解释了三嗪抑制剂的作用机理。
