摘要（英）：

The invention discloses nanometer barium phosphate modified polymer sulfoaluminate cement-based marine corrosion-resistant coating. The nanometer barium phosphate modified polymer sulfoaluminate cement-based marine corrosion-resistant coating is prepared from the following raw materials in parts by weight: 60 to 80 parts of sulfoaluminate cement, 20 to 40 parts of coal ash, 20 to 30 parts of silicon dioxide, 40 to 80 parts of organic silicon modified polyacrylic ester emulsion, 20 to 40 parts of water, 1 to 5 parts of a water-reducing agent, 0.5 to 2 parts of a defoaming agent, 1 to 3 parts ofa dispersing agent and 1 to 5 parts of film-forming aids. The invention also discloses a preparation method of the nanometer barium phosphate modified polymer sulfoaluminate cement-based marine corrosion-resistant coating. The nanometer barium phosphate modified polymer sulfoaluminate cement-based marine corrosion-resistant coating has excellent tensile strength, anti-permeability, adhesive strength and corrosion resistance, and has wide application space.
