The invention discloses an anti-seepage type fireproof coating for a tunnel. The anti-seepage type fireproof coating is prepared by mixing raw materials in parts by weight as follows: 80-88 parts of portland cement, 30-34 parts of baitelan cement, 20-30 parts of a styrene-acrylic emulsion, 30-35 parts of bisphenol epoxidized resin emulsion, 6-8 parts of potassium hydroxide, 10-11 parts of magnesium hydroxide, 10-14 parts of starch, 6-8 parts of ammonium dichromate, 6-8 parts of light calcium carbonate, 10-16 parts of ethyl cellulose, 5-9 parts of glass fiber, 14-18 parts of fly ash hollow floating beads, 3-5 parts of diatomaceous earth, 6-8 parts of vermiculite, 6-8 parts of mica, 6-8 parts of aluminum triphosphate, 8-10 parts of pottery clay and 5-7 parts of pentaerythritol. A product has good fireproof performance, has an anti-seepage function and makes up the defect of high probability of seepage of a conventional fireproof coating. The fireproof coating has high bonding property and excellent overall performance and is easy to use and operate during construction and suitable for the fields of traffic tunnels, civil defense, underground buildings and the like.
