The invention discloses a fluorine-silicon nanometer waterproof heat-insulating composite material and a preparation method thereof. The preparation method comprises the following steps: 1) adding fluorine-containing polymer resin and xylene into a jacket cylinder, and carrying out uniform stirring; 2) heating liquid in the cylinder to 40-60 DEG C, then adding a nanometer silicon solution while stirring, carrying out stirring for 20-40 minutes while keeping a temperature at 40-60 DEG C, and carrying out cooling to 20-30 DEG C to obtain a prepared fluorine-silicon nanometer resin solution for later use; 3) adding fluorine-containing polymer resin, a dispersing agent and inorganic pigment powder into the material cylinder, and carrying out dispersing at a high speed to prepare pigment paste;4) adding the fluorine-silicon nanometer resin solution into the material cylinder, adding the pigment slurry, adding an antifoaming agent, a leveling agent, a substrate wetting agent, elastic resin,a thermal insulation material 5 and butyl acetate, and carrying out stirring to obtain a component A of the fluorine-silicon nanometer waterproof heat-insulating composite material, wherein the component A and a coating component B form the fluorine-silicon nanometer waterproof heat-insulating composite material. The waterproof heat-insulating coating is good in weather resistance and corrosion resistance and friendly to environment.
