Abstract

Rosin thiourea imidazole quaternary ammonium salt (RTIQAs) was synthesized by connecting rosin and imidazole units via thiourea linker, and its inhibitive action on the corrosion of CRS (cold rolled steel) in 1.0 M HCl solution was fully investigated. The results demonstrate that RTIQAs is an efficient mixed-type inhibitor with the maximum inhibition efficiency of 95%. The adsorption rule on the CRS surface fully complies with Langmuir isotherm. The efficient inhibition of RTIQAs can also be verified by AFM, SEM and CLSM (confocal laser scanning microscope). The direct adsorption proof of RTIQAs molecules on steel surface can be further presented in EDX and XPS.

盐酸溶液中松香硫脲咪唑季铵盐在钢表面的吸附和抑制作用

松香硫脲咪唑季铵盐（RTIQAs）是由松香和咪唑单元通过硫脲连接剂连接合成的，充分研究了其对1.0 M HCl溶液中CRS（冷轧钢板）的缓蚀作用。结果表明，RTIQAs 是一种高效的混合型抑制剂，最大抑制效率可达 95%。RTIQAs 在 CRS 表面的吸附规律完全符合 Langmuir 等温线。RTIQAs 的高效抑制作用还可以通过原子力显微镜、扫描电子显微镜和共聚焦激光扫描显微镜（CLSM）得到验证。RTIQAs 分子在钢表面的直接吸附证明可进一步通过 EDX 和 XPS 来呈现。
