| description | Aiming at the current situation that the existing acidizing corrosion inhibitors are difficult to apply in high temperature, high concentration acid, and other complex conditions, this article uses nano-SiO2 as the core and preferably functional monomers to synthesize nano-SiO2@octadecylbisimidazoline quaternary ammonium salt (nano-SiO2@OBQA). Analytical methods such as nuclear magnetic resonance, infrared, and scanning electron microscopy were used for characterization. The corrosion inhibition performance of the N80 steel sheet by nano-SiO2@OBQA in 20% concentrated hydrochloric acid was studied using the high-temperature corrosion testing machine and adsorption isotherm model combined with quantum chemistry calculations to explore its mechanism of action. The results show that nano-SiO2@OBQA has good high-temperature resistance. When the temperature is 180℃ and the dosage of nano-SiO2@OBQA is 4%, the corrosion inhibition rate is 61.42 g·m−2·h−1. Studies have shown that the adsorption of nano-SiO2@OBQA on the surface of the N80 steel sheet follows the Langmuir isotherm adsorption model, which is spontaneous chemical adsorption. |
