[Objective] In response to the serious pollution and strong corrosiveness of traditional strong acid cleaner, this study aims to develop an environmentally friendly water-based cleaner that integrates efficient rust removal, good lubricity, and low corrosiveness. [Method] Using MXene(a two-dimensional layered material) as the core and silane coupling agent KH560 and polyetheramine M2070 as the shell, a core–shell structured solvent-free nanofluid(MXene NFs) was synthesized via covalent grafting. The MXene NFs were then dispersed in a water-based system(GHC) composed of glycerol, 1-hydroxyethylidene-1,1-diphosphonic acid(HEDP), and citric acid, with thiourea added as a corrosion inhibitor to obtain the MXene NFs/GHC cleaner. The structure and composition of MXene NFs were characterized by Fourier transform infrared spectroscopy(FT-IR), X-ray photoelectron spectroscopy(XPS), transmission electron microscopy(TEM), thermogravimetric analysis(TG), and X-ray diffractometry(XRD). The comprehensive performance was evaluated through rust removal test, electrochemical measurements, and friction and wear test. [Result] The mass fraction of organic shell of MXene NFs was 72.9%, and the nanofluid remained stably dispersed in the GHC system without sedimentation after standing for one month. With the optimized formulation of 100 g/L HEDP, 100 g/L citric acid, and 50 g/L thiourea, the MXene NFs/GHC cleaner achieved a rust removal rate of 0.066 g/h on Q235 steel, and a corrosion inhibition efficiency of 48.1%. Citric acid and HEDP dissolved the rust layer through coordination, forming soluble complexes that avoided secondary residues, while thiourea formed a physically adsorbed film on the steel surface, effectively inhibiting corrosion. Compared with the pure GHC system, the friction coefficient of MXene NFs/GHC decreased from 0.162 to 0.106, the wear volume decreased from 8.76 × 10-2 mm3 to 7.36 × 10-3 mm3, and the wear rate dropped to 6.81 × 10-7 mm3/(N·m), demonstrating significantly enhanced lubrication performance. [Conclusion] The MXene NFs/GHC cleaner integrates multiple functions of cleaning, lubrication, and anti-corrosion, showing promising prospects for environmentally friendly applications. This study provides a new strategy for developing multifunctional and eco-friendly water-based cleaners.
