Seepage-proof and fire-proof coating for tunnels
The invention discloses a seepage-proof and fire-proof coating for tunnels. The coating is mainly prepared from raw materials in parts by weight as follows through stirring: 20-30 parts of white cement, 100-105 parts of sulfoaluminate cement, 30-35 parts of Portland cement, a bisphenol epoxy resin emulsion, 30-35 parts of a polyvinyl acetate emulsion, 6-8 parts of aluminium hydroxide, 6-8 parts of starch, 4-8 parts of ammonium dichromate, 5-9 parts of light calcium carbonate, 10-15 parts of hydroxypropyl methyl cellulose, 6-8 parts of hollow glass floating beads, 5-9 parts of kieselguhr, 10-14 parts of vermiculite, 5-9 parts of aluminium stearate, 10-14 parts of mica and 10-14 parts of argil. The coating has the good fire-proof performance, has the seepage-proof function, and overcomes the defect that traditional fire-proof coatings have poor water-proof functions; the fire-proof coating is environment-friendly, high in binding property, easy to construct and operate, excellent in comprehensive performance and applicable to fields of traffic tunnels, civil air defenses, underground buildings and the like.
