Graded super-hydrophobic ice-inhibiting coating for asphalt pavement and preparation method of graded super-hydrophobic ice-inhibiting coating

The invention discloses a graded super-hydrophobic ice-inhibiting coating for an asphalt pavement and a preparation method of the graded super-hydrophobic ice-inhibiting coating, and belongs to the technical field of road engineering. The invention provides a graded super-hydrophobic ice-inhibiting coating for an asphalt pavement and a preparation method of the graded super-hydrophobic ice-inhibiting coating in order to solve the problem that in the prior art, application of a super-hydrophobic material to pavement anti-icing research is deficient. The coating adopts a three-stage spraying process of brushing a sealing layer, brushing coating slurry and spraying the coating slurry. The super-hydrophobic ice-inhibiting coating with a complex micro-nano hierarchical structure is finally constructed through interaction of all the components of the coating and a spraying process, the super-hydrophobic performance of the asphalt pavement is remarkably improved through the coating, an extremely high contact angle i
