The application discloses an elastic anti-pollution flashover anti-icing anti-corrosion coating material and a preparation method thereof. The coating material comprises, in parts by weight, 80-120 parts of a silicone modified polycarbonate polyurethane resin, 2-10 parts of a modifier, 15-30 parts of a pigment and filler, 0.5-1 part of a defoaming agent, 0.5-1 part of a leveling agent and 0.5-1 part of a dispersing agent. The modifier is a nitrogen-doped porous carbon loaded with phosphate or a nitrogen-doped porous carbon modified by zinc nitride loaded with phosphate. The nitrogen-doped porous carbon and the nitrogen-doped porous carbon modified by zinc nitride in a layered structure are added to the coating system as a barrier modifier, and the carbon material loaded with phosphate is added to the coating. Under long-term use of the coating, the phosphate released by the carbon material loaded with phosphate can be stably hydrolyzed, so that loose iron oxides are converted into a corrosion-resistant phosphide film, and the corrosion is inhibited.

The invention relates to a four-layer metal oxide / metal / metal / metal oxide coating that provides multispectral camouflage. Said coating having camouflage characteristics provides thermal, multispectral and electromagnetic protection by offering reflection, absorption and transmission properties against infrared (IR), ultraviolet (UV) and electromagnetic waves. As the ceramic layer, it comprises titanium dioxide (TiO₂), titanium nitride (TiN), zinc oxide (ZnO), zinc nitride (Zn₃N₂), iron (III) oxide (Fe₂O₃), iron (II) oxide (FeO), iron nitride (Fe₂N), aluminium oxide (Al₂O₃), aluminium nitride (AlN), tin oxide (SnO₂), magnesium oxide (MgO), magnesium nitride (Mg₃N₂), calcium oxide (CaO), calcium nitride (Ca₃N₂), cobalt oxide (CoO), tungsten oxide (WO₃), vanadium oxide (V₂O₅), vanadium nitride (VN), manganese oxide (MnO₃), chromium oxide (Cr₂O₃), chromium nitride (CrN), nickel oxide (NiO), boron oxide (B₂O₃), boron nitride (BN) or barium oxide (BaO). As the metal layer, copper (Cu), aluminium (Al), nickel (Ni), cobalt (Co), silver (Ag), gold (Au), iron (Fe), tungsten (W), tin (Sn), zinc (Zn), magnesium (Mg), vanadium (V), chromium (Cr), lead (Pb) or platinum (Pt) is used to provide protection against thermal cameras and UV rays, while electromagnetic waves are blocked. The adhesive-free layered structure is resistant to wear and provides versatile protection for military clothing and mobile platforms by optimising reflection and transmission.
