Description

Technical Field

[0001] This utility model relates to the field of calcium silicate board technology, and in particular to a high-temperature resistant, high-strength, ultra-low thermal conductivity calcium silicate board. Background Technology

[0002] Calcium silicate board not only has the functions of traditional gypsum board, but also has the advantages of superior fire resistance, high temperature resistance, moisture resistance, and ultra-long service life. It is widely used in ceilings and partitions of industrial and commercial buildings, as well as in home decoration, furniture lining, billboard lining, warehouse shelving, raised access floor, and wall panels for indoor projects such as tunnels.

[0003] Calcium silicate boards have high compressive strength and can withstand certain pressures; however, large areas of calcium silicate boards can be bent, and when used as ceilings, they can only bear their own weight and a small portion of the external hanging force. Therefore, in order to ensure sufficient flatness when used in multiple applications, a large number of fixing points need to be set, otherwise flatness is difficult to guarantee; their flexural strength is limited, which restricts their application range; calcium silicate boards have certain thermal insulation properties and can play a role in thermal insulation to a certain extent, but their thermal conductivity is at a medium level, making them unsuitable for applications with ultra-low thermal conductivity. Utility Model Content

[0007] Furthermore, both sides of the grid plate and the aerogel plate are bonded together between the two calcium silicate plate layers.

[0008] Furthermore, the calcium silicate board layer is provided with a mesh cloth on the side facing the grid plate.

[0009] Furthermore, the grid plate is a fiberglass plate with a grid.

[0010] Furthermore, the outer ring side of the aerogel plate is wrapped with a filling felt, which fills the space between the aerogel plate and the inner wall of the grid plate.

[0011] Furthermore, the filling felt is an aerogel felt.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The present invention will be further described in detail below with reference to the embodiments.

[0024] Specific embodiments of the high-temperature resistant, high-strength, and ultra-low thermal conductivity calcium silicate board provided by this utility model:

[0025] Please see Figure 1-5 The high-temperature resistant, high-strength, and ultra-low thermal conductivity calcium silicate board comprises two calcium silicate board layers 1; a grid plate 2 is connected between the two calcium silicate board layers 1, and the grid plate 2 is a fiberglass board with a grid; the thermal conductivity of the fiberglass board is lower than that of the calcium silicate board layers 1, the density is close to that of the calcium silicate board layers 1, and the flexural strength is higher; the fiberglass grid plate 2 connects and supports the calcium silicate board layers 1, significantly improving the flexural strength, ensuring the flatness of the board, avoiding bending deformation, and improving the stability of the board; the fiberglass grid plate 2 can also provide sufficient compressive strength.

[0026] Each grid of the grid plate 2 is filled with an aerogel plate 3, and the two sides of the aerogel plate 3 are flush with the two sides of the grid plate 2. The aerogel plate 3 contains nanoporous aerogel with ultra-low thermal conductivity and better heat insulation effect than the calcium silicate board layer 1. It is located between the two calcium silicate board layers 1, which greatly improves the heat insulation performance of the board and is suitable for occasions with ultra-low thermal conductivity requirements.

[0027] Both sides of the grid plate 2 and the aerogel plate 3 are bonded to the two calcium silicate board layers 1 by adhesive. The calcium silicate board layer 1 is provided with a mesh cloth 4 on the side facing the grid plate 2. The adhesive used for connection is adhered to the mesh cloth 4. The mesh cloth 4 and the adhesive firmly bond the grid plate 2 and the aerogel plate 3 to the calcium silicate board layer 1 on both sides, so that the board has a stronger overall integrity and improves the crack resistance of the surface calcium silicate board layer 1.

[0028] In this embodiment, the thickness of the calcium silicate board layer 1 is 5-10 mm; the thickness of the grid plate 2 and the aerogel plate 3 is 5-10 mm. The grid of the grid plate 2 is larger than the grid of the mesh cloth 4; the grid of the grid plate 2 is a square grid, and the side length of the positive direction grid is 40-60 mm.

[0029] Since the outer ring of the rigid aerogel plate 3 is difficult to fully adhere to the inner side of the grid of the mesh plate 2, complete adhesion requires extremely high cutting precision. Therefore, in this embodiment, the outer ring of the aerogel plate 3 is wrapped with a flexible strip-shaped filling felt. The filling felt is filled between the aerogel plate 3 and the inner wall of the grid of the mesh plate 2 to avoid gaps between the aerogel plate 3 and the inner wall of the grid of the mesh plate 2, thus ensuring the quality of the plate.

[0030] In this embodiment, the filling felt is aerogel felt 5. The aerogel felt 5 can be squeezed and filled between the aerogel plate 3 and the inner wall of the grid plate 2 to avoid the generation of internal gaps. It also has ultra-low thermal conductivity, ensuring that the plate has ultra-low thermal conductivity.

[0031] Production process: First, place a layer of calcium silicate board 1, evenly brush on a layer of glue, lay a layer of mesh cloth 4, and then apply glue on the side of the mesh cloth 4, applying glue in multiple places in a matrix arrangement;

[0032] A grid plate 2 is placed on the upper side of the grid cloth 4 corresponding to the calcium silicate plate 1. The strip aerogel felt 5 is wrapped around the outside of the aerogel plate 3 with its ends touching, and then inserted into the grid of the grid plate 2. Aerogel plates 3 and aerogel felt 5 are inserted into each grid of the grid plate 2.

[0033] Apply adhesive to the upper side of the aerogel plate 3; then lay a layer of mesh cloth 4 on the upper side, and evenly brush adhesive on one side of another calcium silicate plate 1, with the brushed side facing and corresponding to the mesh plate 2 placed on the upper mesh cloth 4; pre-bond the blanks to form the shape.

[0034] A hydraulic press applies pressure to one or more of the prepared plates, pressing each layer of the blank tightly. The grid plate 2 has strong compressive strength, while the aerogel plate 3 has poor compressive strength. During the pressing process, the grid plate 2 can protect the aerogel plate 3 from being crushed. It can withstand greater pressure. Under pressure, the adhesive penetrates between the grid of the aerogel plate 3 and the grid plate 2, and each layer is tightly connected to the whole, thus producing a high-temperature resistant, high-strength, ultra-low thermal conductivity calcium silicate board.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
