The invention discloses a rain erosion preventing elastic protective coating for an antenna housing. The component A is composed of polyaspartic acid ester resin, fumed silica, an auxiliary agent, a titanate coupling agent, a solvent and the like, the component B is an elastic prepolymer synthesized from hydroxyl polyester color paste, polyol, aliphatic isocyanate, the solvent and the like, and the tensile strength and the elongation at break of the coating film are adjusted through molecular structure design, so that the coating film has relatively good wear resistance and elasticity, and the service life and the safety of the radome can be prolonged. |
