The invention discloses a marine sound insulation composite board and a manufacturing method, and the marine sound insulation composite board comprises a frame which is provided with a containing cavity, and the containing cavity is provided with a first opening and a second opening which are opposite to each other in the thickness direction of the frame; the first panel is connected with the frame and covers the first opening; the second panel is connected with the frame and covers the second opening; the partition panel is located in the containing cavity and connected with the frame, the containing cavity is partitioned into a first cavity and a second cavity in the thickness direction of the frame, a first sound insulation material is arranged in the first cavity, and a second sound insulation material is arranged in the second cavity; and the material density of the first panel, the spacing panel and the second panel is greater than that of the frame. According to the sound insulation composite board for the ship, the overall weight of the sound insulation composite board for the ship can be reduced to the maximum extent by using the light material as the force-bearing frame, meanwhile, the sound insulation effect can be enhanced by combining and using the panel with the large density to cover and seal the sound insulation material, and it is ensured that the overall sound insulation effect of the composite board is good.
本申请公开了一种船用隔声复合板及制造方法,船用隔声复合板包括:框架,框架具有容纳腔,容纳腔具有沿框架厚度方向相对的第一开口和第二开口;第一面板,与框架连接并盖封第一开口;第二面板,与框架连接并盖封第二开口;间隔面板,位于容纳腔内并与框架连接,将容纳腔间沿框架厚度方向间隔成第一空腔和第二空腔,第一空腔内设有第一隔声材料,第二空腔内设有第二隔声材料;其中,第一面板、间隔面板和第二面板的材质密度大于框架的材质密度。通过使用较为轻质的材料作为承力的边框,能够最大程度减轻船用隔声复合板的整体重量,同时结合使用密度较大的面板盖封隔声材料,能够加强隔声效果,确保复合板整体的隔声效果具有良好表现。
