Description

A composite acetate board Technical Field

[0001] This utility model relates to the field of acetate sheets, specifically a composite acetate sheet. Background Technology

[0002] Acetate board, also known as cellulose acetate board or acetate resin board, is a type of board made primarily of cellulose acetate. It possesses excellent heat resistance, corrosion resistance, and weather resistance, and is widely used in furniture manufacturing, architectural decoration, and advertising production. However, compared to traditional wood-based boards, acetate board softens and deforms when exposed to high temperatures, affecting its normal use. Summary of the Invention

[0003] The purpose of this invention is to provide a composite acetate sheet to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a composite acetate board includes a core board, the core board is covered with a layer of cellulose acetate, and multiple honeycomb cavities are formed on both the upper and lower sides of the core board, so that both the upper and lower sides of the core board have a honeycomb structure, and the cellulose acetate layer fills the honeycomb cavities.

[0005] Through the above technical solutions, the core board configuration increases the composite acetate board's resistance to deformation at high temperatures, and the honeycomb cavity configuration increases the connection strength between the acetate fiber layer and the core board.

[0006] Preferably, the honeycomb cavities on the upper and lower sides are aligned one to one, and through holes are provided between the honeycomb cavities on the upper and lower sides, with the cellulose acetate layer filling the through holes.

[0007] Through the above technical solution, the opening of through holes further improves the connection strength between the cellulose acetate layer and the core board, and prevents the cellulose acetate layer from separating from the surface of the core board at high temperatures.

[0008] Preferably, mounting holes are also provided between the honeycomb cavities located at the four corners of the core board. A support rod is fixed in the mounting hole. The length of the support rod is greater than the thickness of the core board, and the part of the support rod that extends beyond the core board is consistent with the thickness of the cellulose acetate layer on the surface of the core board.

[0009] The above technical solution allows the support rod to be positioned at the middle position in the thickness direction of the cellulose acetate layer, ensuring the accuracy of the thickness of the cellulose acetate layer covering the core board surface.

[0010] Preferably, the core board is made of solid wood.

[0011] The above technical solutions enable the core board to have high strength.

[0012] Preferably, the cellulose acetate layer is made of cellulose acetate adhesive.

[0013] The above technical solutions improve the strength and fire resistance of composite acetate boards.

[0014] The beneficial effects of this utility model are: the core board increases the deformation resistance of the composite acetate board at high temperatures; the honeycomb cavity increases the connection strength between the acetate fiber layer and the core board; and the support rod helps to position the core board at the middle position in the thickness direction of the acetate fiber layer, ensuring the accuracy of the thickness of the acetate fiber layer covering the core board surface.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description of the utility model is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this composite acetate sheet are described in detail below:

[0024] One embodiment of this utility model:

[0025] Referring to Figures 1-5, this utility model provides a composite acetate board, including a core board 30, which is covered with a layer of cellulose acetate 10. Multiple honeycomb cavities 31 are opened on both the upper and lower sides of the core board 30, so that both the upper and lower sides of the core board 30 have a honeycomb structure. The cellulose acetate layer 10 fills the honeycomb cavities 31. The honeycomb cavities 31 on the upper and lower sides are aligned one by one. Through holes 32 are opened between the honeycomb cavities 31 on the upper and lower sides. The cellulose acetate layer 10 fills the through holes 32. The honeycomb cavities 31 located at the four corners of the core board 30 are also connected and have mounting holes 33. A support rod 20 is fixed in the mounting hole 33. The length of the support rod 20 is greater than the thickness of the core board 30. The part of the support rod 20 that extends above the core board 30 is consistent with the thickness of the cellulose acetate layer 10 on the surface of the core board 30. The core board 30 is made of solid wood, and the cellulose acetate layer 10 is made of cellulose acetate adhesive.

[0026] In the manufacturing process of this utility model, multiple honeycomb cavities 31 are cut on both sides of the core board 30 to form a honeycomb structure on its surface. Through holes 32 are opened between the honeycomb cavities 31 on both sides. Mounting holes 33 are opened on the bottom wall of the honeycomb cavities 31 located at the four corners of the core board 30. Four support rods 20 are respectively inserted into the four mounting holes 33 and fixed in them with glue.

[0027] Then it is placed in an acetate sheet molding mold. The length and width of the mold cavity are greater than the length and width of the core plate 30, and the thickness of the mold cavity is the same as the length of the support rod 20, so that the core plate 30 is located at the center of the mold cavity.

[0028] The mixed cellulose acetate adhesive is poured into the mold cavity, and the core board 30 is immersed in the adhesive. After the adhesive solidifies, the cellulose acetate adhesive solidifies on the surface of the core board 30, in the honeycomb cavity 31 and in the through hole 32 to form a cellulose acetate layer 10 covering the core board 30.

[0029] The support rod 20 can be fixed in the installation position by nailing or bolting through it, making the composite acetate board provided by this utility model easy to lay.

[0030] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
