The invention discloses three-component sound-absorbing cotton and a preparation method thereof, and belongs to the technical field of sound-absorbing materials. The three-component sound-absorbing cotton comprises three components, wherein an upper surface layer (1), a first adhesive layer (2) a middle layer (3), a second adhesive layer (4) and a lower surface layer (5) are sequentially arrangedin a stacked mode from top to bottom. The middle layer (3) is made of polyurethane porous foam materials, the upper surface layer (1) and the lower surface layer (5) are both made of mixed fibers of polyethylene glycol terephthalate fibers and polypropylene fibers, and the first adhesive layer (2) and the second adhesive layer (4) are both made of adhesives. The invention further discloses the preparation method of the three-component sound-absorbing cotton. The three-component sound-absorbing cotton is of a three-layer structure, has excellent sound-absorbing and sound-insulating effects, andis small in overall surface density.
