精品 精品 铝合金表面低温防腐保护剂的制备 摘 要 自组装膜是分子在溶液(或气态)中自发通过化学键牢固地吸附在固体基底上而形成的有序分子膜。由于其堆积紧密、结构稳定，因而具有抑止腐蚀的作用，其在金属腐蚀与防护领域有广阔的应用前景和重要的理论价值。 本文找到了一种简单可行的铝合金的低温表面腐蚀检测方法：比色法。通过大量腐蚀实验找出铝合金的低温表面保护剂的最佳制备配比为MBI:MBO:BTA=3:1:1，复合缓蚀剂最佳含量为0.31%的时候缓蚀效果，最佳反应温度为室温。本防腐保护剂在室温22℃，33%的NaCl、2mol/L HCl混合溶液中缓蚀率为74.2%；在低温-20℃，33%的NaCl、2mol/L HCl混合溶液中缓蚀率为95.1%。本文同时还探讨了金属有机化合物作为催化剂和缓蚀剂的反应机理。 关键词： 铝合金 ,防腐保护剂，缓蚀剂，分子自组装 Preparation of Corrosion Protection Solvent for Aluminum alloy Surface Speciality：Applied Chemical ABSTRACT Self-assembled monolayer of molecules in solution (or gaseous) through spontaneous chemical bond firmly adsorbed on the solid substrate and formed an orderly molecular membrane. Because of its close accumulation, structural stability, which has curbed the role of corrosion. Metal corrosion in the field of protection and broad prospects for application and important theoretical value. In this paper, found a simple and feasible in low-temperature alloy surface corrosion detection method-colorimetric method. Through numerous experiments to identify corrosion of low-alloy surface protection for the best ratio of Preparation is MBI: MBO : BTA = 3:1:1, the best inhibitor compound content of 0.31% when the effect of inhibition, The optimum reaction temperature to room temperature. Also explore the metal catalyst and organic compounds as inhibitors of the reaction mechanism.
