Description

technical field [0001] The invention relates to a graphene powder coating used for internal structural components of an EMU. Background technique [0002] With the improvement of the comprehensive technical performance of high-speed EMUs, higher requirements are put forward for the aesthetics, corrosion resistance, flame retardancy and environmental protection of trains. Chrome-free epoxy primers and polyurethane topcoats are mostly used for internal structural parts of high-speed EMUs. The surface of this coating is plump, flat and smooth, but its anti-corrosion function, solvent resistance and flame retardancy still need to be improved, and its adhesion to the component substrate is poor, and its service life is not long. [0003] The content in the Background Art section is only the technology known to the inventors, and does not necessarily represent the prior art in the field. Contents of the invention [0004] Aiming at one or more of the existing problems in the p...
