Description

Technical Field

[0001] The utility model belongs to the technical field of home decoration wood, and in particular relates to a stable three-layer laminated cabinet door structure. Background Art

[0002] In the field of home decoration, most cabinet doors are made of wood boards. Existing wood boards include artificial boards and log boards. Among them, log boards are carefully made from a whole piece of log. They are not only environmentally friendly, but also have natural wood grain and high texture. However, log resources are limited, the output is small, and its moisture resistance is relatively weak. In addition, the production process of log furniture is complicated and the cost is high. Therefore, log boards are mainly limited to the application of a few high-end products.

[0003] The artificial board includes an inner core board and an outer skin layer, wherein the existing inner core board is generally made of any one of the base materials such as plywood, density board, particle board, etc.; but the strength, environmental protection, moisture resistance and other properties of the artificial board are different due to the different base materials. For example, in the prior art, a Chinese patent with publication number CN2902693Y discloses an artificial composite board, which also mentions that the existing artificial board has low strength, heavy weight and high cost; however, although this prior art improves the strength, it cannot achieve the texture of solid wood and has poor visual effects.

[0004] In addition, the inner core boards made of plywood, density board, particle board and other boards on the market have the following disadvantages:

[0005] 1) The inner core board is made of plywood, which has many layers and uses a large amount of glue. For example, in the prior art, the Chinese patent with publication number CN2043548U discloses a bamboo and wood shavings composite plywood, which mentions the use of bamboo and wood shavings to make composite plywood. In addition to using a large amount of glue and being environmentally unfriendly, this prior art also uses one-time hot pressing molding, and this hot pressing molding technology requires higher production conditions and technical level, making the production cost of the overall composite plywood higher. The prior art also has multi-layer solid wood plywood to maintain the texture of the log, but this multi-layer solid wood plywood is also bonded by multiple layers of glue, and has poor environmental performance.

[0006] 2) The inner core board is made of density board, which is cheap but not moisture-proof and easy to deform, and it is difficult to meet the requirements of long-term use;

[0007] 3) The inner core board is made of particle board, which has good moisture resistance but low strength and poor load-bearing capacity.

[0008] Therefore, there is an urgent need for a stable three-layer laminated cabinet door structure to solve the above problems and meet the market's multiple demands for beauty, practicality and environmental protection. Summary of the invention
