The invention discloses an anti-seepage tunnel fire retardant coating which is mainly prepared by stirring the following raw materials in parts by weight: 100-105 parts of refractory cement, 20-30 parts of portland blast furnace slag cement, 30-35 parts of an acrylate polymer emulsion, 10-15 parts of an allyl acetate resin emulsion, 5-7 parts of sodium hydroxide, 10-15 parts of perlite, 4-8 parts of flyash, 3-4 parts of ammonium dichromate, 2-6 parts of light calcium carbonate, 10-16 parts of polypropylene short fiber, 2-6 parts of carboxymethylcellulose, 7-9 parts of kieselguhr, 4-9 parts of vermiculite, 3-8 parts of ammonium polyphosphate, 5-8 parts of pottery clay and 3-5 parts of pentaerythritol. The anti-seepage tunnel fire retardant coating is good in fireproof performance, and has an anti-seepage function; the defect of a poor waterproof function of the traditional fire retardant coating is compensated; the fire retardant coating is environmentally friendly, high in caking property, easy to construct and operate, good in overall performance, and suitable for the fields of traffic tunnels, civil air defence, underground buildings and the like.
