Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic fiberboards, and in particular relates to a novel high-temperature resistant ceramic fiberboard. Background Art

[0002] Ceramic fiberboard is a product made of ceramic fiber wool as the main raw material. It has excellent properties such as high temperature resistance, high mechanical strength, and thermal shock resistance. It is suitable for thermal insulation of various industrial kilns and is an excellent material for kiln insulation. The Chinese patent with publication number CN219927139U discloses a lightweight high-temperature resistant ceramic fiberboard, including a first high-temperature resistant layer, an anti-aging layer, a ceramic fiber lightweight layer, a reinforcement layer, and a second high-temperature resistant layer.

[0003] However, the structural setting of this patent is relatively simple, and its layer structure setting makes its impact resistance poor and its strength average. Long-term use at high temperature will cause changes in the fiber structure, shrinkage deformation, fiber loss of elasticity, brittle fracture, and reduced fiber strength, etc., which limits the scope of application of the patented ceramic fiberboard and its service life is not high. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a new type of high-temperature resistant ceramic fiberboard, which adopts a multi-layer composite structure arranged in sequence from the center layer to the outside, so that the overall board has the characteristics of high strength, not easy to deform, thermal insulation, strong impact resistance, etc., so that the overall board has a wider range of applications and a longer service life.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: a new type of high-temperature resistant ceramic fiber board, including a supporting and fixing layer, the supporting and fixing layer is a central layer, and the top and bottom surfaces of the supporting and fixing layer are symmetrically arranged outwardly with a reinforcement layer, a ceramic fiber layer, a buffer layer, an impact-resistant protective layer and a wear-resistant layer; wherein the impact-resistant protective layer includes an inner protective layer, and the top and bottom surfaces of the inner protective layer are respectively coated with outer protective layers.

[0006] The impact-resistant protective layer plays an impact-resistant role in the overall plate, and therefore is provided as a composite structure including an inner protective layer and an outer protective layer.

[0007] The thickness of the supporting and fixing layer, ceramic fiber layer and impact-resistant protective layer is greater than that of the reinforcement layer, buffer layer and wear-resistant layer, that is, the supporting and fixing layer, ceramic fiber layer and impact-resistant protective layer are the main layers, and the reinforcement layer, buffer layer and wear-resistant layer are the auxiliary layers.

[0008] The supporting and fixing layer is made of carbon fiber material, and the ceramic fiber layer is made of ceramic fiber wool. The supporting and fixing layer is made of carbon fiber material, which has extremely high strength and light weight. It is used as the central layer to support the whole board, which can effectively reduce the deformation of the board; the ceramic fiber layer is made of ceramic fiber wool, which takes advantage of the characteristics of ceramic fiber wool, such as light weight, high strength, low thermal conductivity, corrosion resistance, and small heat capacity, and plays a good role in thermal insulation.

[0009] The inner protective layer is made of zirconia ceramics, and the outer protective layer is a silicon carbide coating. The inner protective layer utilizes the high-efficiency thermal insulation properties of zirconia ceramics to improve the heat resistance of the entire plate, and plays a role in blocking high temperatures and protecting the ceramic fiber layer; the silicon carbide coating coated on the inner protective layer has the characteristics of high melting point, high hardness, corrosion resistance, and oxidation resistance, which further improves the heat resistance and impact resistance of the impact-resistant protective layer.

[0010] The reinforcement layer is made of metal mesh, the buffer layer is made of foam metal material, and the wear-resistant layer is made of nano-poly glaze polymer resin. The reinforcement layer is made of metal mesh, which not only facilitates the connection between the upper and lower layers, but also plays a certain reinforcement role; the buffer layer is made of foam metal material, which improves the absorption and buffering effect of the overall board against impact force; the wear-resistant layer is made of nano-poly glaze polymer resin, which improves the overall board's anti-corrosion, anti-air scouring, and anti-stripping performance, making the overall board more durable.

[0011] The surface of the buffer layer is provided with a large number of holes arranged in an array, and the arrangement of the holes enables the buffer layer to more effectively absorb the impact force applied from the outside.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model uses the set supporting and fixing layer as the central layer to support the whole plate, which can effectively reduce the deformation of the plate; the set ceramic fiber layer can play a good role in thermal insulation; the set impact-resistant protective layer can play a good impact-resistant effect and protect the whole plate; the set reinforcement layer not only facilitates the connection between the upper and lower layers, but also plays a certain reinforcement role; the set buffer layer can absorb the impact force applied by the outside world and play a buffering role; the set wear-resistant layer improves the erosion resistance, air flow scouring resistance and peeling resistance of the whole plate, making the whole plate more durable; in summary, the utility model adopts a multi-layer composite structure arranged in sequence from the central layer to the outside, so that the whole plate has the characteristics of high strength, not easy to deform, thermal insulation, strong impact resistance, etc., so that the overall plate has a wider range of applications and a longer service life.
