Fire-resistant coating for fire-resistant dike and construction method thereof

The invention relates to a fire-resistant coating for a fire-resistant dike and a construction method thereof. In the fire-resistant coating for the fire-resistant dike, a component A formed by mixing portland cement, high-alumina cement, expanded perlite, expanded vermiculite and reinforced fibers, and a component B formed by mixing polyethylene-vinyl acetate copolymer emulsion with water are taken as raw materials; during construction, the component A and the component B are respectively prepared in advance; then the component A and the component B are sufficiently and evenly mixed; and spraying can be performed to obtain the fire-resistant coating. The fire-resistant coating for the fire-resistant dike has excellent fire-resistant performance, and is high in bonding strength, resistant to high temperature and high in anti-cracking performance. The fire-resistant coating for the fire-resistant dike, which is described in the invention, can be used as a fire-resistant coating for indoor and outdoor steel str
