Submarine silencing damping material

Abstract

The invention discloses a submarine silencing damping material, and relates to the technical field of damping materials, the submarine silencing damping material comprises a silencing damping material, the silencing damping material is of a multi-layer structure, the silencing damping material comprises a damping material layer 1, an adhesive 1, a metal wire mesh, an adhesive 2 and a damping material layer 2, the first damping material layer is bonded with the metal wire mesh through a first adhesive, and the metal wire mesh is bonded with the damping layer through a second adhesive. Accordingto the submarine noise elimination damping material, the first damping material layer is arranged, the first damping material layer is composed of the high polymer and the inorganic filler, can be used for a free damping structure and a constraint damping structure, and has good damping performance, good flexibility and excellent flame retardant property, and the material has the characteristicsof oil stain resistance, seawater resistance, salt mist resistance, mold resistance, no toxicity and the like, physical tests show that the vibration acceleration level of a part treated by the material is reduced by more than 5dB, and the material is suitable for being used in a submarine cabin.

Description

technical field [0001] The invention relates to the technical field of damping materials, in particular to a sound-absorbing and damping material for a submarine. Background technique [0002] The boat is a recognized strategic weapon. It can move flexibly underwater and is used to attack warships on the opponent's surface and submarines in the water. It can also attack important military targets on land; when necessary, it can also undertake mine-laying, Reconnaissance and transportation of soldiers and important military supplies. Submarines have good concealment and surprise attack capabilities, and can continue to sail for a long time and long distances in the water. [0003] The main contradiction on the modern battlefield has gradually changed from "strike" and "anti-strike" to "discovery" and "anti-discovery". Anechoic tile technology is one of the most effective measures to improve the stealth performance of submarines and improve their combat effectiveness and sur...
