The invention discloses a sound-insulation self-leveling material and a preparation method thereof, and belongs to the technical field of building materials. The sound-insulation self-leveling material is prepared from the following raw materials in parts by weight: 70 to 90 parts of gypsum-based gelling composite material, 18 to 30 parts of filler, 5 to 7 parts of glass fiber filaments, 0.5 to 1.2 parts of polycarboxylic acid water reducing agent, 0.5 to 1.5 parts of retarder, 1 to 2.5 parts of vinyl acetate-ethylene copolymerized redispersible latex powder, 0.1 to 0.5 part of defoaming agent, 0.1 to 0.5 part of water-retaining agent and 18 to 25 parts of water. The self-leveling material prepared by taking the modified gypsum as a base material of the gypsum-based gelling composite material has good mechanical properties, low water absorption and sound insulation performance.
