[0001] The utility model relates to the technical field of organic and inorganic material composite processing and its application, concretely relates to a ceramic heat -insulation refractory macromolecular composite board. BACKGROUND

[0002] With the implementation of the "double carbon" policy and the vigorous development of the new energy industry, the new energy and green material industry has developed rapidly, and the market scale of new energy and green materials is also expanding. The ceramic polymer composite material is a new type of refractory material that can form a complete and hard shell structure at high temperature, which can insulate external flame to some extent and play a role in heat insulation and fire resistance.

[0003] At present, the research on ceramic polymer materials at home and abroad is increasing, but under the action of continuous high temperature, its heat insulation performance and flame retardant performance are not superior in actual application, such as the actual heat insulation protection effect is not very ideal when applied between the electric cores in the field of new energy vehicles.

[0004] Therefore, it is necessary to develop a composite board with excellent heat insulation and fire resistance and ceramic performance. SUMMARY

DETAILED DESCRIPTION

[0018] In the following, the application is further described in combination with the drawings and specific embodiments, and it should be noted that, under the condition of no conflict, the embodiments described below or the technical features can be combined to form new embodiments.

[0019] In the description of the application, it should be understood that the terms "upper", "lower", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0020] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0021] like Figure 1 As shown, a ceramicized heat-insulating and fire-resistant polymer composite board includes a fireproof fiber cloth layer 1, a strength reinforcing layer 2, a porous heat-insulating and fire-resistant gypsum layer 6, and a ceramicized polymer sheet layer 5. An adhesive layer 7 is provided between each layer. The materials of each layer are arranged in sequence and are bonded together through the adhesive layer 7 to form a composite board 4. A damping rotation structure 3 is provided on one side of the composite board 4.

[0022] In practical applications, the ceramicized polymer sheet 5 is placed at the bottom, followed by the porous heat-insulating and fire-resistant layer, then the strength-reinforcing layer 2, and finally the fire-resistant fiber cloth layer 11. This gives the composite material excellent heat insulation, fire resistance, and ceramic-forming properties. When the ceramicized polymer sheet 5 is subjected to flame impact, during the period of transformation into a ceramic structure, the mechanical properties of the ceramicized polymer material are poor, making it unable to withstand external forces and prone to shrinkage. Therefore, adding the fire-resistant fiber cloth layer 1 provides support during this period, preventing the material from shrinking and deforming severely due to flame impact. Simultaneously, due to the inherent fire-retardant properties of the fire-resistant fiber cloth layer 1, its presence significantly improves the heat insulation and fire resistance of the composite material. By adding a strength-reinforcing layer 2 between the fire-resistant fiber cloth layer 1 and the ceramicized polymer sheet layer 5, the composite board 4 can acquire high strength, heat resistance, and fire resistance. It will not melt or drip at high temperatures, further improving the strength and fire resistance of the composite material. Secondly, by adding a porous heat-insulating and fire-resistant gypsum layer 6 between the strength-reinforcing layer 2 and the ceramicized polymer sheet layer 5, the porous structure of the gypsum layer 6 provides excellent heat insulation performance. Furthermore, the porous gypsum is not easily combustible, thus enhancing the heat insulation and fire resistance of the composite material, achieving a V-0 flame retardant rating in UL-94. In a flame environment, it not only maintains dimensional stability and prevents deformation but also rapidly ceramicizes, transforming into a ceramic-like material, thus resisting external damage. This allows for applications in wiring harnesses or battery packs of new energy vehicles, as well as in fire-resistant cables. Finally, the damping rotation structure 3 is used for further compression, which can make the bonding of each layer more secure and allow more than two composite panels 4 to be spliced ​​together, thus providing design versatility.

[0023] A further improvement is made to the damping rotation structure 3, which includes a U-shaped fixing plate 31, a mounting plate 33, and a spring damping shaft 32 disposed on one side of the U-shaped fixing plate 31 and the mounting plate 33, wherein one side of the composite plate 4 is disposed within the U-shaped fixing plate 31.

[0024] The damping rotation structure 3 consists of three parts: a U-shaped fixing plate 31 and a mounting plate 33 connected by a spring-damped rotating shaft 32, allowing rotation. The thickness of the U-shaped fixing plate 31 is 1–2 mm, the diameter of the rotating shaft is 5–10 mm, and the thickness of the mounting plate 33 is 1–2 mm. The U-shaped fixing plate 31 and the composite board 4 are fixed with two screws and two nuts, while the mounting plate 33 is fixed with four screws, for example, for fixing to a wall.

[0025] A further improvement is made in that the thickness of the ceramicized polymer sheet 5 is 1 to 10 mm.

[0026] The thickness of the ceramicized polymer sheet 5 is 2–10 mm, mainly composed of a polymer matrix and ceramicized fillers. The polymer matrix is ​​either a polyolefin matrix or a silicone rubber matrix. Polyolefin is preferred as the matrix due to its advantages such as economy, environmental friendliness, good processing performance, and high mechanical properties. The ceramicized fillers include kaolin, mica powder, talc powder, wollastonite, montmorillonite, sodium borate, feldspar, etc.

[0027] A further improvement is made to the fact that the thickness of the fireproof fiber cloth layer 1 is 0.5 to 2 mm.

[0028] The fireproof fiber cloth layer 1 is made of at least one of glass fiber, quartz fiber, high silica fiber, and basalt fiber, using a plain weave with high density.

[0029] A further improvement is that the thickness of the strength-reinforcing layer 2 is 0.5-2 mm, and it is woven from aramid fibers; the thickness of the porous heat-insulating and fire-resistant gypsum layer 6 is 2-8 mm, and it is prepared by a porous gypsum molding mold; the thickness of the adhesive layer 7 is 0.2-1 mm, and the adhesive layer 7 is composed of inorganic water glass and its bonding-related additives.

[0030] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
