Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber heat-resistant board technology, and in particular to an environmentally friendly ceramic fiber heat-resistant board. Background Technology

[0002] Heat-resistant boards are a common type of building material in modern life. Due to their excellent heat resistance, they stand out among many materials and have a very wide range of applications. In terms of building decoration, heat-resistant boards can be used for wall and ceiling decoration in high-temperature indoor areas. They are not only beautiful and elegant, but also ensure that no harmful substances are released in high-temperature environments, thus protecting the health of residents.

[0003] However, existing heat-resistant boards are not effective in resisting pressure and cannot provide a buffering effect. Furthermore, their toughness decreases after prolonged use, making them prone to brittleness and cracking. In addition, some heat-resistant boards may have a certain impact on the environment during production and use, failing to meet environmental protection requirements. Therefore, there is a need for a heat-resistant board that has both good heat resistance and environmental protection characteristics.

[0004] Therefore, given that the existing heat-resistant boards have poor compressive strength, and their toughness decreases after prolonged use, making them prone to brittleness and cracking, and that some heat-resistant boards are made of materials that do not meet environmental protection requirements, an environmentally friendly ceramic fiber heat-resistant board can be designed. This board will have stronger compressive strength, and its toughness will not decrease significantly after prolonged use, reducing the possibility of the heat-resistant board becoming brittle and cracking. Furthermore, it will be made of environmentally friendly materials. Utility Model Content

[0005] In order to overcome the problems that existing heat-resistant boards have poor compressive strength, and their toughness decreases after long-term use, making them prone to brittleness and cracking, in addition, some heat-resistant boards are made of materials that do not meet environmental protection requirements.

[0006] The technical solution of this utility model is as follows: an environmentally friendly ceramic fiber heat-resistant board, comprising a fiber matrix layer and a ceramic fiber board, further comprising a reinforcing layer, a ceramic fiber felt and a surface coating, the fiber matrix layer comprising an intermediate layer, the upper and lower surfaces of which are respectively fixedly connected to an upper surface layer and a lower surface layer, the upper and lower ends of the fiber matrix layer being sequentially fixedly connected to a reinforcing layer, a ceramic fiber felt and a ceramic fiber board, the surface of the ceramic fiber board being coated with a surface coating, the reinforcing layer comprising a surrounding panel, the inner walls of the surrounding panel having mortises on all four sides, tenons being engaged in the mortises, transverse reinforcing rods being fixedly connected between corresponding tenons on the left and right sides of the surrounding panel, and longitudinal reinforcing rods being fixedly connected between corresponding tenons on the front and rear sides of the surrounding panel.

[0007] Preferably, the upper and lower surface layers are bonded together on the upper and lower surfaces of the intermediate layer to form a fiber matrix layer. The tenons at both ends of the transverse and longitudinal reinforcing rods are aligned with the mortises of the inner wall of the enclosure to obtain a reinforcing layer. The reinforcing layer, ceramic fiber felt, and ceramic fiber board are bonded together on the upper and lower surfaces of the fiber matrix layer in sequence. Finally, a surface coating is applied to the surface of the ceramic fiber board.

[0008] Preferably, the fiber matrix layer adopts a three-dimensional mesh structure or a honeycomb structure.

[0009] Preferably, the interior of the enclosure is filled with filler material using adhesive, and the transverse and longitudinal reinforcing bars are integrally formed.

[0010] Preferably, the ceramic fiber board includes a substrate, and a groove is formed on the side of the substrate near the ceramic fiber felt, and a reinforcing material is fixedly connected in the groove by an adhesive.

[0011] Preferably, the reinforcing material is a metal mesh or glass fiber mesh, and the area of ​​the reinforcing material is greater than 90% of the substrate area.

[0012] Preferably, the surface coating is a high-temperature and aging-resistant coating, which uses silicone resin, polytitanate, or heat-resistant pigments.

[0013] Preferably, the thickness of the ceramic fiber felt is 10-50mm, and it is made of any one of the following: aluminosilicate-based ceramic fiber felt, high-alumina ceramic fiber felt, zirconium-containing ceramic fiber felt, mullite-based ceramic fiber felt, and alumina-silica composite fiber felt.

[0014] The beneficial effects of this utility model are as follows: The unique design of the reinforcing layer greatly enhances the overall strength of the board. Mortise and tenon joints are precisely engaged on the inner walls of all four sides of the panel, and a stable support frame is constructed through the connection of transverse and longitudinal reinforcing rods. This structure effectively disperses stress when the board is subjected to high temperatures and external forces, improving its compressive strength, reducing the risk of deformation and damage, extending its service life, and lowering replacement costs and safety hazards caused by board damage. The use of ceramic fiber felt improves the board's toughness; even after prolonged use, its toughness does not significantly decrease, effectively improving its resistance to brittleness and cracking. Regarding the issue of cracking, the combination of the fiber matrix layer, ceramic fiber board, and ceramic fiber felt works synergistically to improve heat resistance. The fiber matrix layer provides basic structural support for the board, while the ceramic fiber board and ceramic fiber felt, with their excellent high-temperature resistance, effectively block heat transfer, allowing the board to maintain stable physical and chemical properties even at high temperatures. In addition, the surface coating not only improves the appearance of the board but also adds a protective barrier, enhancing its corrosion resistance and wear resistance. Made of environmentally friendly materials, it does not release harmful substances during production and use, meeting the environmental protection requirements of modern society.

A groove 402 is provided on the side of the substrate 401 near the ceramic fiber felt 3. A reinforcing material 403 is fixedly connected in the groove 402 by adhesive. The reinforcing material 403 adopts a metal mesh or glass fiber mesh cloth. The area of ​​the reinforcing material 403 is greater than 90% of the area of ​​the substrate 401.

[0023] Please see Figure 1In this embodiment, the surface coating 5 is a high-temperature and aging-resistant coating, which is made of silicone resin, polytitanate or heat-resistant pigment. The thickness of the ceramic fiber felt 3 is 10-50mm, which is any one of aluminum silicate-based ceramic fiber felt, high-alumina ceramic fiber felt, zirconium-containing ceramic fiber felt, mullite-based ceramic fiber felt and alumina-silica composite fiber felt.

[0024] During operation, the upper surface layer 102 and the lower surface layer 103 are bonded to the upper and lower surfaces of the intermediate layer 101 to form a fiber matrix layer. The tenons 203 at both ends of the transverse reinforcing rod 204 and the longitudinal reinforcing rod 205 are aligned with the mortises 202 on the inner wall of the enclosure 201. The enclosure 201 is filled with filler 206 using adhesive to obtain a reinforcing layer. The reinforcing material 403 is fixed in the groove 402 of the substrate 401 with adhesive to obtain a ceramic fiber board.

The fiber matrix layer provides basic structural support for the board, while the ceramic fiber board and ceramic fiber felt 3, with their excellent high-temperature resistance, can effectively block heat transfer, allowing the board to maintain stable physical and chemical properties even in high-temperature environments. In addition, the surface coating 5 not only improves the appearance quality of the board but also adds a protective barrier, enhancing its corrosion resistance and wear resistance. Made of environmentally friendly materials, it does not release harmful substances during production and use, meeting the environmental protection requirements of modern society. This addresses the problems of existing heat-resistant boards having insufficient compressive strength, reduced toughness after prolonged use, and easy brittleness and cracking.
