Sound absorbing type tunnel fireproof coating
The invention discloses a sound absorbing type tunnel fireproof coating. The coating is prepared by mixing raw materials in parts by weight as follows: 70-78 parts of Portland cement, 30-38 parts of AEC (alunite expansive cement), 20-30 parts of white cement, 30-35 parts of methyl vinyl methyl ester, 10-18 parts of a vinyl acetate resin emulsion, 12-14 parts of potassium hydroxide, 4-8 parts of starch, 3-6 parts of ammonium dichromate, 10-18 parts of light calcium carbonate, 10-15 parts of polypropylene staple fiber, 8-10 parts of carboxymethyl cellulose, 10-16 parts of coal ash glass beads, 5-9 parts of kaolin, 5-9 parts of vermiculite and 5-7 parts of ammonium polyphosphate. The sound absorbing type tunnel fireproof coating has long fireproof time and good adhesion performance, is convenient to use during construction and suitable for various tunnel walls and has a sound absorbing function on the basis of a fireproof function.
