The invention discloses a self-layering gradient fluorosilicon-based super-hydrophobic coating and a preparation method of same. The self-layering gradient fluorosilicon-based ultrahydrophobic coatingmaterial is composed of a component A and a component B, wherein the component A is composed of: fluorosilicone resin, a diluting solvent, a dispersing solvent, modified nano-SiO2 powder, modified nano silicon sol, a coupling agent, a defoaming agent and a flatting agent; and the component B is aliphatic polyisocyanate. The coating solves the defects that a super-hydrophobic coating in the priorart has complex preparation process, is long in hard drying time, is high in crosslinking curing temperature and has a double-layer bottom. The coating can reach more than 151 degrees in water contact angle and is about 3 degrees in rolling angle. The preparation method is simple and is free of expensive and complex equipment. The coating not only has high adhesion force and super-hydrophobicityand has good flexibility.
