The invention discloses a superhydrophobic coating preparation method, a coating prepared therethrough, and an application of the coating in the production of a highly-transparent superhydrophobic coating layer. The superhydrophobic coating preparation method comprises the following steps: adding a certain volume of a solvent, a cosolvent and a catalyst into a container one time, stirring the added substances at a certain rotating speed for a period of time, adding a certain volume of silicate ester and fluorine-containing siloxane, and continuously reacting all above substances at room temperature for a certain period of time to obtain the coating. The superhydrophobic coating prepared in the invention can be sprayed, dip-spread or dip-coated on glass, sheet paper, steel or other different substrates, and the transmittance of the produced coating layer in a visible light range reaches 92% or more. Compared with coating layers in the prior art, the produced coating layer has the advantages of simple production method, low cost, and facilitation of large-scale industrial production, has multiple uses in window glass, skyscraper light curtains, mobile phone screens and computer screens, and has great commercial values.
