composite wood

technical field

The utility model relates to the field of composite wood boards, in particular to a composite wood board with anti-deformation and warpage and low production cost.

Background technique

Solid wood boards are made of raw wood through cutting and grinding, and can be used as basic materials for furniture such as cabinets, tables and chairs, or as flooring and decorative panels. But in fact, the log is not easy to obtain, so it is expensive, and the characteristics of the log are limited. Under the influence of various environmental factors, a single log structure is very easy to be damp and warped.

Then it appeared that thin wood chips were pasted on a stable material surface (such as a dense board) to form a multi-layered wooden board, hoping to reduce the amount of logs used. However, the wood chip and the attached material have different moisture expansion rates. Therefore, when the whole is damp and deformed, the thin wood chip will be degummed and cause the layers of the structure to separate from each other. Therefore, some related companies repeatedly proposed to stack solid wood boards cut from the same log to form a multi-layer structure, and make the wood grains of each layer of solid wood boards stack in a vertical manner to solve the instability of wood chips combined with different materials. However, this method returns to the problem of log cost. The manufacturing cost of this type of structure is extremely high, and in fact, it still cannot respond to the expansion and contraction phenomenon derived from the characteristics of the log.

In order to make the multi-layered wooden board less prone to deformation due to physical phenomena or moisture, the designer of this utility model gathered many years of relevant experience, and then conceived a composite wood board, hoping to effectively improve the lack of the current multi-layered log structure.
