Technical Field

[0001] This utility model relates to the field of ecological board technology, specifically a multi-layer composite fireproof ecological board. Background Technology

[0002] Fire-resistant ecological boards are made of fire-resistant materials and are often used in interior buildings, as well as in the decoration of various furniture and cabinets, and in some panels. They are made of multi-layer boards and mostly use adhesives to connect and combine the layers.

[0003] Chinese utility model patent CN212979463U discloses an eco-friendly board, which includes a substrate layer, an adhesive layer, a wood layer, and a paper-faced layer. The adhesive layer is formed between the substrate layer and the wood layer, and the paper-faced layer is formed on the outer surface of the wood layer. The thickness of the paper-faced layer is 1.1–1.3 mm. The thickness of the wood layer is 0.6–0.9 mm.

[0004] Based on existing solutions and actual production and processing, the existing multi-layer composite fireproof ecological board requires a large amount of adhesive to connect the layers during processing. The adhesive contains formaldehyde, making it difficult to reduce formaldehyde release. Relying solely on the material for sound insulation results in poor sound insulation performance. Therefore, we propose a multi-layer composite fireproof ecological board to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-layer composite fireproof ecological board to solve the problems mentioned in the background art, such as the need for a large amount of adhesive to connect the layers during processing, the formaldehyde content in the adhesive, the difficulty in reducing formaldehyde release, and the poor sound insulation effect due to relying solely on the material for sound insulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite fireproof ecological board, comprising a solid wood board, a first fireproof board, and a second fireproof board.

[0007] The solid wood board has mounting grooves at both the top and bottom. A first fireproof board is installed on the top of the solid wood board, and a connecting plate is integrally connected to the bottom of the first fireproof board. A second fireproof board is installed below the solid wood board, and a connecting plate is integrally connected to the top of the second fireproof board. A rectangular groove is opened inside the connecting plate, and a corrugated board is installed inside the rectangular groove.

[0008] The second fireproof board is attached to the bottom of a first impregnated adhesive film paper, and the first fireproof board is attached to the top of a second impregnated adhesive film paper.

[0009] Preferably, the connecting plate is connected to the solid wood board via a mounting groove.

[0010] Preferably, the rectangular slots are equally spaced inside the connecting plate.

[0011] Preferably, the height of the corrugated plate is equal to the thickness of the connecting plate, and the outer side of the corrugated plate is in contact with the inner wall of the rectangular groove.

[0012] Preferably, both the first fireproof board and the second fireproof board are connected to the solid wood board by adhesive bonding.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the multi-layer composite fireproof ecological board, the setting of connecting plate and installation groove can reduce the amount of adhesive used, making it more environmentally friendly, and the sound insulation effect is improved by the equally spaced rectangular grooves and corrugated plates;

[0014] 1. The installation is modular, with the connecting plate snapping into the mounting groove. The design of the connecting plate and the mounting groove reduces the contact area between the first fireproof board and the solid wood board, as well as between the second fireproof board and the solid wood board, thus reducing the amount of adhesive used and making it more environmentally friendly.

[0015] 2. Rectangular grooves are equally spaced inside the connecting plate. The equally spaced rectangular grooves and corrugated plates can reduce sound transmission and improve the sound insulation effect of the fireproof ecological board.

[0016] The equally spaced rectangular grooves reduce material usage. The height of the corrugated plate is equal to the thickness of the connecting plate, and the height of the rectangular groove is equal to the thickness of the connecting plate. The corrugated plate is located inside the rectangular groove. During installation, the corrugated plate is simply inserted into the rectangular groove, making installation of the corrugated plate convenient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 Existing multi-layer composite fireproof ecological boards require a large amount of adhesive to connect the layers during processing. The adhesive contains formaldehyde, making it difficult to reduce formaldehyde release. Relying solely on the material for sound insulation results in poor sound insulation performance. To solve this technical problem, this embodiment discloses the following technical content.

[0025] A multi-layer composite fireproof ecological board includes a solid wood board 1, an installation groove 2, a first fireproof board 3, a second fireproof board 4, a connecting plate 5, a rectangular groove 6, a corrugated board 7, a first impregnated adhesive film paper 8, and a second impregnated adhesive film paper 9.

[0026] The top and bottom of the solid wood board 1 are provided with mounting grooves 2. A first fireproof board 3 is provided on the top of the solid wood board 1, and a connecting plate 5 is integrally connected to the bottom of the first fireproof board 3. A second fireproof board 4 is provided on the bottom of the solid wood board 1, and a connecting plate 5 is integrally connected to the top of the second fireproof board 4. A first impregnated film paper 8 is pasted and connected to the bottom of the second fireproof board 4, and a second impregnated film paper 9 is pasted and connected to the top of the first fireproof board 3.

[0027] The connecting plate 5 is connected to the solid wood board 1 via the mounting groove 2. The first fireproof board 3 and the second fireproof board 4 are both connected to the solid wood board 1 by adhesive bonding. Figure 1 , Figure 2 and Figure 4 As shown, since the connecting surfaces of the first fireproof board 3 and the solid wood board 1, as well as the connecting surfaces of the second fireproof board 4 and the solid wood board 1, are mostly occupied by the connecting plate 5, after the connecting plate 5 is inserted into the mounting groove 2, it is only necessary to apply adhesive to the outer ends of the first fireproof board 3 and the second fireproof board 4 to connect the first fireproof board 3 and the second fireproof board 4 with the solid wood board 1, thereby reducing the use of adhesive and thus reducing the release of formaldehyde.

[0028] Fireproofing is achieved through the first fireproof board 3 and the second fireproof board 4. The first fireproof board 3 and the second fireproof board 4 can be magnesium oxide board or ceramsite board.

[0029] A rectangular groove 6 is provided inside the connecting plate 5, and a corrugated plate 7 is installed inside the rectangular groove 6. The rectangular groove 6 is equally spaced inside the connecting plate 5, and the outer side of the corrugated plate 7 is in contact with the inner wall of the rectangular groove 6.

[0030] During use, the equally spaced corrugated plates 7 can block the propagation of sound. The sound waves will be reflected multiple times in the cavity of the rectangular groove 6 during propagation, forming a sound wave superposition effect and reducing the propagation of sound. Since the height of the corrugated plate 7 is equal to the thickness of the connecting plate 5, the corrugated plate 7 is stuck between the solid wood board 1 and the first fireproof board 3 and the solid wood board 1 and the second fireproof board 4. During installation, it is only necessary to insert the corrugated plate 7 into the interior of the rectangular groove 6. It is not necessary to use glue to fix the corrugated plate 7.

[0031] The above completes a series of operations for the multi-layer composite fireproof ecological board. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.
