Description
技术领域
本发明涉及一种船用甲板结构，具体涉及一种船用甲板敷料结构。
背景技术
根据SOLAS海上人命安全公约及其船舶规范要求，在海洋工程和船舶甲板上，必须敷设不同防火等级的覆盖层，此覆盖层即成为甲板敷料。甲板敷料是敷设于船舶甲板上的覆盖材料，主要起到隔热、降噪、防滑等作用，根据需要的不同，船舶必须使用不同类型的甲板敷料，所有的船舶用敷料都必须具备隔热、降噪、消烟、耐腐等条件。而对于船舶一些普通生活舱室处于机舱、娱乐室等震动、噪声大的舱室周围，这就容易影响船员的正常作息和健康，因此需要对这些舱室进行减震降噪保护，以此来提高船员居住生活的舒适性，减轻船舶自身重量，提高船舶的灵活性。尤其对于一些海工、科研、邮轮等船舶有着重要的作用。
发明内容
发明目的：本发明的目的是为了克服现有技术中的不足，提供一种结构简单，减震降噪效果好，舒适耐用的高减震高隔声阻尼结构。
技术方案：为了解决上述技术问题，本发明所述的高减震高隔声阻尼结构，它包括设在钢甲板上的阻尼层，在所述阻尼层上设有约束层，在所述约束层上设有甲板敷料基层，所述阻尼层的厚度在1-2mm之间，所述约束层的厚度在10-15mm之间，所述甲板敷料基层的厚度在10-15mm之间，所述阻尼层、约束层和甲板敷料基层都设在舱壁之间。
所述约束层和甲板敷料基层的厚度比为1：1。
在本发明中主要包括以下部分：
①阻尼层
材质：改性聚氨酯、云母粉、氢氧化铝、分散剂、消泡剂、流平剂等。
②约束层
材质：环氧树脂、酚醛胺固化剂、微硅粉、氢氧化铝、分散剂、消泡剂、流平剂等。
③甲板敷料基层
材质：普通硅酸盐水泥、丙烯酸乳液、醋酸乙烯-乙烯共聚乳液、水、陶砂、玻化珍珠岩、工业矿砂、减水剂、纤维素醚等。
有益效果：本发明与现有技术相比，其显著优点是：本发明整体结构简单，采用阻尼层，主要是衰减钢甲板的振动频率，起到对钢甲板减震降噪的作用；采用甲板敷料基层，主要起减震降噪作用，进一步提高隔声指数；采用厚度比为1：1的约束层和甲板敷料基层，进一步提高整体性能，起到普通舱室的减震降噪，有效提高了船员居住生活的舒适性，减轻了舰艇自身重量，也提高了舰艇的灵活性，适用于军事舰艇和普通船舶的船员居住和活动舱室。
附图说明
图1是本发明的结构示意图。
具体实施方式
