Super-hydrophobic coating based on self-embedded micro-nano structure and preparation method thereof

The invention discloses a super-hydrophobic coating based on a self-embedded micro-nano structure and a preparation method of the super-hydrophobic coating. The preparation method comprises the following steps: uniformly loading hydrophobic modified nanoparticles to the surface of a coating with a micron-sized coarse structure, and then partially embedding the hydrophobic modified nanoparticles into the surface of the coating with the micron-sized coarse structure in a high-pressure heating manner, and cooling to room temperature to obtain the super-hydrophobic coating with the self-embedded micro-nano structure. The organosilicon modified thermoplastic acrylic resin with low surface energy and the thermoplastic micron particles are adopted to construct a micron-sized coarse structure, and then the characteristics of a thermoplastic material are utilized, so that the nano-sized hydrophobic particles are embedded into the surface of the micron-sized coarse structure in the phase change process of the micron-si
