Preparation method of room-temperature self-curing low-infrared-emissivity super-hydrophobic coating

The invention discloses a preparation method of a room-temperature self-curing super-hydrophobic coating with low infrared emissivity. The method comprises the following steps: 1, polishing, cleaning and drying to obtain a pretreated base material; 2, adding fluorocarbon resin, flaky metal powder and diatomite into absolute ethyl alcohol, and uniformly stirring at room temperature; 3, adding PTFE and uniformly stirring at room temperature, and then adding perfluorodecyl triethoxy silane and uniformly stirring at room temperature; 4, adding isophorone diamine, and uniformly stirring at room temperature; and 5, coating the surface of a pretreated base material, and standing and curing at room temperature to obtain the super-hydrophobic coating. By controlling the raw materials and the addition amount, the flaky metal powder and the diatomite are uniformly bonded and filled in a cross-linked copolymerization structure of the fluorocarbon resin, and a tightly-combined super-hydrophobic coating is formed on the su
