The invention discloses a noise-reducing and vibration-absorbing material for ships and a preparation method thereof, the noise-reducing and vibration-absorbing material comprises a noise-reducing reinforcing layer and damping rubber layers, and the damping rubber layers are located on the two sides of the noise-reducing reinforcing layer; the noise reduction reinforcing layer is a polyurethane foam reinforcing layer, and the damping rubber layer is prepared from the following components in parts by weight: 25-35 parts of chlorinated butyl rubber, 30-40 parts of chlorosulfonated polyethylene rubber, 25-40 parts of reinforcing filler, 4-7 parts of dibenzoyl peroxide, 5-8 parts of sulfur and 5-10 parts of auxiliaries. Through the structural design of the noise reduction reinforcing layer and the damping rubber layer and the design of components of the noise reduction reinforcing layer and the damping rubber layer, the prepared noise reduction and vibration reduction material has excellent sound absorption, noise reduction and vibration reduction performance and also has excellent flame retardance, the vibration reduction effect and the sound insulation effect of the ship lying cabin are effectively improved, and the service life of the ship lying cabin is prolonged. And the sleep quality of sailors and passengers can be improved.
