The invention relates to the technical field of preparation of polyurethane foam materials, in particular to a sound-absorbing polyurethane foam material as well as a preparation method and application thereof. The sound-absorbing polyurethane foaming material is prepared from the following raw materials in parts by weight: 40 to 50 parts of isocyanate 8223, 80 to 120 parts of polyether polyol, 0.6 to 1.5 parts of a composite catalyst, 1 to 2 parts of DC6070, 2 to 3 parts of water, 0 to 1.5 parts of diethanol amine, 0.2 to 0.5 part of FK-8300 and 0.5 to 1 part of an antioxidant, the preparation method comprises the following steps: S1, mixing and stirring the polyether polyol, the composite catalyst, the DC6070, the water, the diethanol amine and the antioxidant to form a material A; s2, stirring and mixing isocyanate to form a material B; and S3, allowing the material A and the material B to be subjected to foaming injection molding. The sound-absorbing polyurethane foaming material can be used for carpets, and has the advantages that the rebound resilience of foam is improved, and the sound-absorbing effect of the sound-absorbing polyurethane foaming material is improved.
