The invention discloses a sound-proof fire-resistant building material with a humidity adjustment function. The sound-proof fire-resistant building material comprises following ingredients in parts by weight: 25-50 parts of expanded perlite, 30-55 parts of coal ash, 10-20 parts of diatomite, 5-15 parts of gypsum, 12-18 parts of sepiolite, 3-10 parts of mica powder, 2-7 parts of a dispersant, 8-20 parts of phenolic resin, 1.5-4 parts of an acrylonitrile-butadiene-styrene copolymer and 0.5-2 parts of tris(2-carboxyethyl)phosphine. The preparation method comprises the following steps: placing diatomite, gypsum, sepiolite and mica powder in a horizontal kneader to be kneaded so as to obtain a mixture A; mixing phenolic resin, the acrylonitrile-butadiene-phenethylene and a dispersant, and continually stirring at 40-70 DEG C to obtain a mixture B; fully and uniformly mixing expanded perlite, coal ash, tris(2-carboxyethyl)phosphine, the mixture A and the mixture B to obtain a mixture C; extruding the mixture C in an extruder, and cooling to obtain the sound-proof fire-resistant building material with the humidity adjustment function. The sound-proof fire-resistant building material can not only adjust the indoor environmental humidity but also has favorable sound-proof and fire-resistant properties.
