Abstract

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.

Description

technical field [0001] The invention relates to a sound insulation and heat insulation material, a sound insulation and heat insulation structure, a preparation method and an application. Background technique [0002] With the improvement of people's demand for indoor acoustic environment, the importance of floor sound insulation design has become increasingly prominent, among which floating floor is one of the important measures to solve the impact sound insulation. [0003] At present, the floating floor system mostly uses rubber mats, extruded boards, etc. as the sound insulation layer, and uses fine stone concrete, mortar, and gypsum as the protective layer. On the one hand, the total thickness of the sound insulation layer and the protective layer is generally not less than 40mm, which affects the comfort of the living space for the user, and affects the floor height and economic benefits for the developer; on the other hand, it is easy to reduce the thickness There is...
