The invention discloses a novel heat-insulation sound-insulation building material and a preparation method thereof. The novel heat-insulation sound-insulation building material includes the following components in parts by weight: 30-45 parts of fly ash, 20-40 parts of diatomite, 5-10 parts of soda-lime borosilicate glass, 2-6 parts of calcium carbonate, 4-12 parts of glass fiber, 10-20 parts of phenolic resin, 15-20 parts of polyethylene resin, 35-45 parts of an acrylic emulsion, and 3-8 parts of aliphatic dibasic acid alkoxy ester. The preparation method of the novel heat-insulation sound-insulation building material includes the following steps: stirring and mixing fly ash and diatomite evenly to obtain a mixture A; grinding soda-lime borosilicate glass and calcium carbonate and mixing, followed by, together adding the obtained mixture and the mixture A to the acrylic emulsion, and stirring evenly to obtain a mixture B; fusing phenolic resin, polyethylene resin and aliphatic dibasic acid alkoxy ester; cooling to 80-120 DEG C, adding the mixture B and glass fiber into the fused mixture, and continuing a stirring reaction for 30-80 min; and then adding the obtained product into an internal mixing furnace, carrying out an internal mixing reaction, carrying out an extrusion reaction by an extruder, and carrying out cooling molding to obtain the heat-insulation sound-insulation building material.
