The invention discloses a high-performance sound insulation coating and a preparation method thereof. The sound insulation coating is prepared from the following components: modified styrene-acrylic emulsion, crystalline flake graphite, mica powder, glass beads, rubber powder, wood fibers, polyvinyl alcohol fibers, glass fibers, a silane coupling agent, water and auxiliary materials. The preparation method comprises the following steps: sequentially adding the defoaming agent, the thickening agent, the dispersing agent, the wetting agent, the pH regulator and the silane coupling agent into water at room temperature, and uniformly mixing and stirring; sequentially adding crystalline flake graphite, mica powder, glass beads and rubber powder into the material water solution, and uniformly mixing and stirring; dropwise adding a coalescing agent into the solution, and continuously stirring and uniformly mixing in the heating process; sequentially adding the wood fibers, the polyvinyl alcohol fibers and the glass
