Detailed Description

The present invention will be described in detail with reference to the following embodiments and the accompanying drawings.

Example 1

Figure 1 is the utility model discloses a section structure schematic diagram of aerogel heated board. As shown in fig. 1, the aerogel insulation board of the embodiment includes an insulation mortar layer 1, an aerogel layer 2 and a finishing layer 5, which are sequentially disposed; the aerogel layer 2 includes a mesh blanket 3 and an aerogel 4. Fig. 2 is a schematic cross-sectional structure view of a mesh blanket with X-shaped threads crossing each other as an intermediate layer, fig. 3 is a top view of fig. 2, and as shown in fig. 2 and 3, the mesh blanket 3 in the present embodiment has a three-layer structure including an upper surface layer 31, an intermediate layer 32, and a lower surface layer 33, wherein the upper surface layer 31 is a mesh fabric, the lower surface layer 33 is a dense woven fabric, and meshes 311 are provided on the mesh fabric. The intermediate layer 32 is woven by the threads 321 supported and connected to the upper surface layer 31 and the lower surface layer 33 at two ends, respectively, and the threads 321 of the intermediate layer 32 in this embodiment are crossed with each other to form an X shape. As shown in fig. 1, aerogel 4 fills the gaps between adjacent wires 321 of intermediate layer 32; the heat-preservation mortar layer 1 is fixed with the upper surface layer 31, and the finish coat 5 is fixed with the lower surface layer 33.

The aerogel insulation board of the embodiment can be manufactured by the following method:

the woven mesh blanket 3 is laid flat with the upper surface layer 31 under the upper and lower surface layers 33. Aerogel particles are uniformly spread into the mesh blanket 3 through the meshes 311 of the mesh cloth of the upper surface layer 31, so that the aerogel 4 is uniformly filled between the wires 321 crossing each other in the intermediate layer 32 until being filled, thereby forming the aerogel layer 2. Then, coating heat preservation mortar on the surface of the upper surface layer 31 of the grid blanket 3, and drying to form a heat preservation mortar layer 1; next, the upper and lower surfaces are reversed to place the lower surface layer 33 on top. The surface layer 5 is laid on the surface of the lower surface layer 33, the surface layer 5 can be a marble plate, a calcium silicate plate or a silicon-plastic plate, the fixing mode between the surface layer 5 and the lower surface layer 33 is bonding, the bonding material can be cement or an adhesive, and the aerogel insulation board is obtained after curing.

The aerogel insulation board prepared in the embodiment adopts the mesh blanket 3 which takes the dense woven cloth as the lower surface layer 33 and the mesh cloth as the upper surface layer 31 as the framework for wrapping and connecting the aerogel 4, and the mesh cloth and the dense woven cloth are both made of flexible materials, so that the aerogel insulation board is not easy to crack due to good toughness and tear strength; because the aerogel has less density and good waterproof, fire prevention, thermal-insulated, the syllable-dividing effect again, therefore the aerogel heated board that this embodiment prepared is not only light, and waterproof, fire prevention, heat preservation, syllable-dividing are effectual moreover. The middle layer 32 of the mesh blanket 3 in this embodiment is formed by the mutually crossing X-shaped silk threads 321, so that the middle layer of the mesh blanket 3 has good support, and aerogel 4 can be more conveniently filled with aerogel particles when being spread. Of course, a mesh blanket with parallel threads as the middle layer as shown in fig. 4 can be used, and the mesh blanket shown in fig. 4 needs to be pulled up slightly when the upper surface layer 31 is filled with aerogel so that the gaps between the threads 321 are opened sufficiently.

Preferably, the thickness of the intermediate layer 32 is 4-6mm. The thickness of the intermediate layer 32 determines the amount of aerogel filling and also determines the thickness of the aerogel insulation board, and too thin the intermediate layer 32 causes the amount of aerogel filling to be too small, and the insulation and sound insulation effects to be reduced; too thick an intermediate layer 32 would be wasteful and would make the insulation board more space consuming.

Preferably, the thickness of the heat preservation mortar layer 1 is 3-5mm. The heat preservation mortar layer 1 has the shutoff effect to the aerogel in the net blanket 3 on the one hand, and on the other hand self also has the heat preservation function. Because the aerogel is not only light, and it is effectual to keep warm moreover, consequently, does not need to set up heat preservation mortar layer 1 very thickly.

Preferably, the facing layer 5 has a thickness of 3-5mm. The facing layer 5 is primarily for aesthetic purposes, to match the requirements of the decoration of the building, and its thickness can be chosen as desired.

Preferably, the thickness of the lower skin 33 is 1-2mm. Lower surface layer 33 is used for bearing and restriction effect to aerogel 4 on the one hand, and on the other hand is used for bonding the decorative board and forms the finish coat, and thickness is 1-2mm neither waste, can satisfy foretell service function again.

Preferably, the mesh blanket 3 is ceramic fiber, glass fiber or nylon. The fireproof performance of the ceramic fiber and the glass fiber is better; while nylon has better toughness.

It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. The above-described features may be combined with each other as long as they do not conflict with each other. In addition, the above embodiments are only some embodiments, not all embodiments, and all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention based on the embodiments of the present invention.
