The invention discloses a high-temperature-resistant coating for ships. The high-temperature-resistant coating for the ships is prepared from organic silicon resin, ethylcellulose, nano titania, nano aluminium oxide, fluorinated siloxane-acrylate emulsion, silicon carbide, propylene glycol, fluorinated ethylene propylene, polyetheretherketone fibers, polyacrylamide, water, ethanol, a dispersing agent, an antifoaming agent, a leveling agent, a plasticizing agent, a thickening agent and a coupling agent. The high-temperature-resistant coating is excellent in high temperature resistance and resistant to a high temperature ranging from 600 DEG C to 700 DEG C; under a high temperature condition, the coating is structurally stable, less prone to phase-change degradation and generation of detrimental phases, excellent in combination with a substrate and free of cracking and keeps perfectly. In addition, the coating has a superior anti-corrosion function and keeps almost unchanged hardness and adhesion and excellent performances after being soaked in salt mist and salt brine with the salinity being 4% for 25d at 50 DEG C, thereby being applicable to high-temperature protection of the ships.
