Sound insulation and heat preservation material, sound insulation and heat preservation structure, preparation method and application
The embodiment of the invention provides a sound insulation and heat preservation material, a sound insulation and heat preservation structure, a preparation method and application, and compared with the prior art, a better sound insulation and heat preservation effect is achieved under the same thickness. The sound insulation and heat preservation material comprises a heat insulation and sound insulation layer and a concrete protection layer. The heat preservation and sound insulation layer is made of foaming polyurethane, the strength of polyurethane foam is 0.1 Mpa-0. 3 Mpa, and the percentage of closed area is larger than 85%. According to the embodiment of the invention, the thermal insulation and sound insulation layer and the concrete protection layer are arranged; the heat preservation and sound insulation layer is made of foaming polyurethane, the strength of polyurethane foam is 0.1 Mpa-0. 3 Mpa, and the percentage of closed area is larger than 85%; therefore, the sound insulation and heat preservation material has better sound insulation and heat preservation effects; and through the combination of the high-strength fiber concrete protection layer and the heat preservation and sound insulation layer, the requirements of the floating floor slab for strength, sound insulation and heat preservation can be met under the condition that the total thickness of the sound insulation and heat preservation material is smaller than 40 mm.
本发明实施例提供一种隔声保温材料、隔声保温结构、制备方法及应用，以与现有技术相比，在同等厚度下实现更好的隔声保温效果。所述隔声保温材料包括：保温隔声层和混凝土保护层；所述保温隔声层由发泡聚氨酯制成，其中，聚氨酯泡沫的强度为0.1Mpa‑0.3Mpa，闭孔率大于85％。本发明实施例通过保温隔声层和混凝土保护层；所述保温隔声层由发泡聚氨酯制成，其中，聚氨酯泡沫的强度为0.1Mpa‑0.3Mpa，闭孔率大于85％；从而，使隔声保温材料具有更好的隔声保温效果；又通过高强纤维混凝土保护层和保温隔声层的组合，使隔声保温材料的总厚度可在小于40mm的情况下，满足浮筑楼板的强度和隔声保温的需求。
