The invention provides a method for maintaining high reflectivity of a traffic sign line, a super-hydrophobic coating and application of the super-hydrophobic coating, and belongs to the technical field of super-hydrophobic materials. When the traffic sign line is in cloudy and rainy days, rainwater on the surface can rapidly leave from the surface and take away dust and stains adsorbed on the surface due to the repulsive effect of the super-hydrophobic coating on water, the surface of the traffic sign line is kept dry, and the service life of the traffic sign line is prolonged. Therefore, the capture accuracy of the camera of the intelligent driving automobile system on the traffic sign line is improved, and the high reflectivity of the traffic sign line is maintained. The preparation process of the coating is simple, and a good super-hydrophobic effect can be achieved by mixing the prepared silicon dioxide particles with the micro-nano composite structure with a proper amount of ethanol and then spraying th
