The invention provides a sound-absorbing and sound-insulating structure and a ship, the sound-absorbing and sound-insulating structure comprises a substrate, a first sound-absorbing layer, a grid structure, a second sound-absorbing layer and a flame-retardant layer which are stacked, the sound-absorbing and sound-insulating structure has good heat-insulating performance, can meet the requirement for condensation prevention of a cabin to a certain extent when being applied to the ship cabin, and has good sound-absorbing and sound-insulating performance in the thickness direction of the sound-absorbing and sound-insulating structure. The flame-retardant layer is used for preventing flame from spreading, carbonization occurs in the area in contact with the flame, and after a fire source is moved away, combustion is not continued. The grid structure can enable sound waves to be reflected for multiple times in the structure, and sound insulation and sound absorption performance is achieved. The sound absorption and insulation structure has certain elasticity, can be matched with cabin structure size errors caused by ship body structure assembly, welding and the like during field installation, and can ensure that a designed and estimated sound insulation effect can be obtained through small installation errors; when trepanning and in-situ filling treatment are carried out on interference positions of installation structures such as cables, pipelines and horse feet of the cables, the pipelines and the horse feet of the cables and the sound absorption and insulation structures, the process is simple and convenient.
本发明提供一种吸音和隔音结构以及船舶,包括层叠设置的衬底、第一吸音层、网格结构、第二吸音层和阻燃层,具备较好的隔热性能,在船舶舱室中应用时能够一定程度上兼顾舱室防凝露的需求,在吸音和隔音结构的厚度方向,阻燃层用于阻止火焰的蔓延,在与火焰接触的区域发生碳化,当火源移开后,不再继续燃烧。网格结构可使得声波在结构内部发生多次反射,具备隔声和吸声性能。本申请的吸音和隔音结构具备一定的弹性,现场安装时能够匹配船体结构装配、焊接等导致的舱室结构尺寸误差,能够保证较小的安装误差获得设计预估的隔声效果,在电缆、管路及其马脚等安装结构与吸音和隔音结构的干涉处进行开孔及原位填充处理时,工艺简单、便捷。
