The invention discloses a preparation method of a high-sound-insulation vibration-attenuation fireproof damping composite deck covering. The preparation method comprises the following steps: step 1, preparing a damping material; step 2, preparing a dressing layer; and step3, sequentially laying the damping material, a galvanized plate, ceramic wool and the dressing layer on a steel plate from bottom to top. The damping material comprises the following components in parts by weight: 15-35 parts of polyether branched chain polyol, 15-28 parts of polyglycol, 10-16 parts of polydiphenylmethane diisocyanate, 5-20 parts of damping filler, 5-15 parts of inorganic flame retardant, 8-16 parts of phosphorus-nitrogen flame retardant, 2-8 parts of physical expansion flame retardant and 6-10 parts of additives. The damping composite deck covering is suitable for laying on ship cabins and decks, has the wide-temperature-range and wide-frequency sound insulation and vibration reduction characteristics, and can effectively insulate sound by 34-58 dB; and the average vibration attenuation exceeds 29 dB. The deck covering has excellent fire resistance, and passes a low flame spreading test of marinematerials and an A60-grade test of A-grade fire resistance separation.
本发明公开了一种高隔声减振耐火阻尼复合甲板敷料的制备方法，包括以下步骤：第一步，制备阻尼材料；第二步，制备敷料层；第三步，在钢板上由下而上依次敷设阻尼材料、镀锌板、陶瓷棉以及敷料层。阻尼材料的组成及重量份配比为,聚醚型支链多元醇15～35份，聚二醇15～28份，聚合二苯甲烷二异氰酸酯10～16份，阻尼填料5～20份，无机阻燃剂5～15份，磷氮阻燃剂8～16份，物理膨胀阻燃剂2～8份，助剂6～10份。本发明的阻尼复合甲板敷料适用于船舶舱室和甲板的敷设，具有宽温域宽频率的隔声减振特性，可有效隔声34～58dB；平均减振超过29dB。耐火性能优越，通过船用材料的低播焰测试，以及A级耐火分隔的A60等级测试。
