Problems solved by technology

[0002] At present, in the existing technology, the preparation process of solid wood boards mostly adopts three-layer superposition of 2440mm*1220mm boards. During the preparation process, the thickness of the original boards requires very high accuracy. It is easy to cause veneer bulging, which reduces the service life of the board; and when the three layers are superimposed, the waste rate of raw materials is high, which increases the cost; in addition, after the preparation, the board is prone to deformation, insects and mildew.
[0003] After retrieval, the Chinese patent application number is CN201911374270.8, which discloses a production and processing process of solid wood panels, including the production of wood panel raw materials, cutting treatment, multiple grinding, puttying, painting, lacquer surface grinding and topcoat painting The way to stably process the required solid wood panels for use, and by improving the traditional wood panel cutting equipment, it effectively solves the problem that the existing solid wood panels are simple in structure, not only prone to damage during use, but also the surface Relatively simple, it is inconvenient to use as a material in different environments; in the production steps of wood board raw materials in the above-mentioned patents, multiple layers are directly superimposed, resulting in the unutilization of small-sized decorative materials, resulting in a high waste rate of raw materials, thus Increased cost; in addition, the plate is not carbonized, and the plate is easy to deform, infested with insects, and moldy

Embodiment 1

[0039] An environmentally friendly waterproof and fireproof multi-layer solid wood board, including a core board and a panel. The core material of the core board is imported Thai rubber wood, and the panel is pure imported board with a moisture content of 10% to 12%. The texture is clear and the quality is selected. The best board; the panel as a whole is 2440mm (length) * 100 ~ 200mm (width) unit boards are assembled on the surface of the core board, and finally processed into a 2440mm (length) * 1220mm (width) overall board that is compatible with the core board The splicing structure; and the thickness of the panel is 3mm, and the thickness of the core board is 15mm or 18mm or 20mm.

Embodiment 2

[0041] An environment-friendly waterproof and fireproof multi-layer solid wood board production process, which includes the following steps in sequence:

[0042] S1: Prepare the core board. The core material is imported Thai rubber wood. After the log is sawn, it is carbonized at high temperature, and the moisture content is within 8%, and then processed into a standard board of 2440mm (length) * 1220mm (width);

[0043] S2: Prepare the panel. The panel is made of pure imported board with a moisture content of 10% to 12%. Cut the panel to 2440mm (length) * 100 to 200mm (width), and use a precision saw to saw it into 3mm thin slices; cut the spliced ​​core Board cut to 2440mm (length) * 100 ~ 200mm (width);

[0044] S3: Three-layer superimposition, use a new type of high-pressure cold press to apply glue to the 3mm thin panel and core board, and then press the three-layer superposition for 3 to 5 hours, so that the core board and the panel are completely tightly bonded with zer...

Embodiment 3

[0055] A manufacturing process of an environment-friendly waterproof and fireproof multi-layer solid wood board comprises the following steps in sequence:

[0056] S1: Prepare the core board. The core material is imported Thai rubber wood. After the log is sawn, it is carbonized at high temperature, and the moisture content is within 8%, and then processed into a standard board of 2440mm (length) * 1220mm (width);

[0057] S2: Prepare the panel. The panel is made of pure imported board with a moisture content of 10% to 12%. Cut the panel to 2440mm (length) * 100 to 200mm (width), and use a precision saw to saw it into 3mm thin slices; cut the spliced ​​core Board cutting is 2440mm (length) * 100 ~ 200mm (width);

[0058] S3: Three-layer superimposition, use a new type of high-pressure cold press to glue the 3mm thin panel and core board, and then press the three layers for 4.5 hours. During cold pressing, adjust the air pressure at 2Mpa to 3.5Mpa to make the core board and the...

Abstract

The invention discloses an environment-friendly waterproof and fireproof multilayer solid wood board and a manufacturing process thereof, relates to the field of processing and production of solid wood boards, and aims at avoiding material waste and improving deformation resistance, dust prevention, insect generation prevention and mildew prevention. The multilayer solid wood board comprises a core board and a panel, imported Thailand rubber wood is used as the core material of the core board, a pure imported board is used as the panel, the moisture content is 10%-12%, and the board with cleartexture and the best quality is selected; the manufacturing process specifically comprises the following steps that the core board is prepared, imported Thailand rubber wood is used as the core material, high-temperature carbonization treatment is conducted after log saw cutting, and then the log is spliced into a 2440 mm (length) * 1220 mm (width) standard board. According to the environment-friendly waterproof and fireproof multilayer solid wood board and the manufacturing process thereof, imported Thailand rubber wood is adopted as the core material, and high-temperature carbonization treatment is carried out after log sawing; the finally-prepared three-layer total solid wood board is not prone to deformation, cracking and expansion; and in addition, the board has the advantages of being low in water content and not prone to insect generation and mildewing.
