Embodiment 1

[0051] The composite thermal insulation and sound insulation board 100 of the present embodiment is as figure 2 As shown, it includes a first layer 110 , a polyurea airgel layer 120 and a second layer 130 stacked in sequence. The above three layers are glued together in sequence. Both the first layer 110 and the second layer 130 are plaster layers on paper. The thicknesses of the first layer 110, the polyurea airgel layer 120 and the second layer 130 are 12 mm, 5 mm and 12 mm, respectively. The polyurea airgel layer 120 has a density of 15kg / cm 3 . The size of the composite thermal insulation and sound insulation board 100 of this embodiment is 1.2m×2.4m.

Embodiment 2

[0053] The composite thermal insulation and sound insulation board 200 of the present embodiment is as image 3 As shown, in addition to the first layer 210, the polyurea airgel layer 220 and the second layer 230 stacked in sequence, it also includes a first fireproof layer 240 outside the first layer 210 and a fire protection layer outside the second layer 230. The second fire protection layer 250 . The above five layers are glued together in sequence. Both the first layer 210 and the second layer 230 are plaster layers on paper. The thicknesses of the first layer 210, the polyurea airgel layer 220 and the second layer 230 are 12 mm, 2 mm and 12 mm, respectively. The thicknesses of the first fireproof layer 240 and the second fireproof layer 250 are both 5 mm. The polyurea airgel layer 220 has a density of 15kg / cm 3 . The size of the composite thermal insulation and sound insulation board 200 of this embodiment is 1.2m×2.4m.

Embodiment 3

[0055] The difference between this embodiment and Embodiment 2 is that the composite thermal insulation and sound insulation board does not include the second fireproof layer. When used as a building board and implemented in practice, the first fireproof layer is placed on the side away from the wall, and the second layer is placed on the side close to the wall and is in contact with the wall surface.

Abstract

The invention discloses a composite thermal insulation and sound insulation board. The composite thermal insulation and sound insulation board includes the first layer, the polyurea airgel layer and the second layer stacked in sequence; the first layer and the polyurea airgel layer form a first sound-absorbing interface for sound attenuation, and the second layer and the polyurea airgel layer A second sound-absorbing interface for sound-absorbing is formed between the urea airgel layers. In the process of sound transmission, the sound is transmitted across the medium several times, resulting in a large loss of sound energy. Secondly, the self-assembled micro-nano-level porous structure of polyurea nanofibers and nanoparticles in the polyurea airgel layer of the composite thermal insulation board can effectively attenuate the sound wave energy and achieve the effect of sound insulation and noise reduction. At the same time, since the polyurea airgel layer is a porous material, it can also function as heat preservation. In addition, the polyurea airgel layer of the present invention has a large size and can be directly used as a building board. Therefore, the composite thermal insulation and sound insulation board of the present invention can be used as a building material, and has the function of thermal insulation and sound insulation.

Description

technical field [0001] The invention relates to the field of thermal insulation and sound insulation materials, in particular to a composite thermal insulation and sound insulation board. Background technique [0002] With the development of social industrialization, the surrounding environment of our life is filled with more and more noise, such as the noise generated by construction projects and vehicles, and the noisy noise in crowded places, etc. These noises have caused a lot of damage to our lives. big impact. Therefore, there is an increasing demand for soundproofing materials that can reduce these noises. Although some materials have the function of sound insulation, they tend to reduce the thermal insulation effect. [0003] The thermal insulation and sound insulation materials in construction mainly include the following categories: the first category is glass wool, rock wool, etc., which have disadvantages such as heavy weight, complicated construction, serious ...
