Description

Bamboo Composite Panel

This case is about a bamboo integrated board, in particular a bamboo integrated board floor with a wood grain imitating a ring-porous oak.

Bamboo plywood is a type of board made from bamboo, which is made by processing, gluing and compressing bamboo to give it a larger size while retaining the natural characteristics of bamboo.

Bamboo plywood is a superior building material with multiple unique properties. Its excellent strength and hardness make it a highly durable and load-bearing choice. At the same time, bamboo plywood is relatively light, easy to install and transport, and has more design flexibility when making curved products due to the natural flexibility of bamboo. Its stability enables it to resist environmental changes, and its environmental protection characteristics are reflected in the rapid growth and renewable resource nature of bamboo. In addition, bamboo plywood has strong moisture resistance, suitable for use in humid environments, and is naturally insect-resistant and anti-corrosive, reducing the risk of insect and fungal damage during long-term use. Combining these characteristics, bamboo plywood has become a building material with outstanding comprehensive advantages, widely used in fields such as construction, furniture and decoration.

However, bamboo integrated boards have some disadvantages compared to common oak boards. Since bamboo is mainly composed of parallel fibers and lacks annual rings because there is no cambium between the veneer and the wood, bamboo integrated boards made of bamboo lack natural texture. Oak boards usually have more uniform wood grain and can show unique natural beauty and rich texture. However, the texture design of bamboo integrated boards is limited by the bamboo structure and cannot show such beautiful beauty.

Therefore, how to make the bamboo integrated board have not only its own good board properties but also beautiful texture is an important topic worthy of improvement.

This project aims to provide a bamboo integrated board with a ring-pored oak wood grain structure to show an appearance similar to oak, while retaining the good natural characteristics of bamboo and showing the elegant beauty of oak wood grain.

To achieve the above purpose, the bamboo integrated board includes an original board and an imitation ring-porous oak wood grain structure, and the imitation ring-porous oak wood grain structure is formed on the surface of the original board by an embossing process, wherein the embossing process is to emboss the imitation ring-porous oak wood grain structure on the surface of the original board by a roller in a rolling manner.

As shown in Figures 1 to 3, the bamboo integrated board 1 of this embodiment is made of 4-year-old Phyllostachys pubescens Mazel; Moso bamboo. The bamboo integrated board 1 of this embodiment includes an original board 2 and a wood grain structure 3 of an imitation ring-porous material oak. The imitation ring-porous oak wood grain structure 3 is formed on the surface of the original board 2 (as shown by the dotted line in Figure 1) by embossing, wherein the embossing is to emboss the imitation ring-porous oak wood grain structure 3 on the surface of the original board 2 by rolling. In one embodiment, the imitation ring-porous oak wood grain structure 3 is formed by being recessed downward from the surface of the original board 2, and the recess depth of the imitation ring-porous oak wood grain structure 3 is 6 mm. The following will further explain the method for making the original board 2, that is, the bamboo integrated board 1 that has not been embossed.

First, the middle part of the bamboo stem of the moso bamboo is obtained by felling. For example, the middle part of the bamboo stem 1 to 3 meters above the ground is obtained. Then, the moso bamboo in the middle part of the bamboo stem is split to make a bamboo assembly. For example, the size of the bamboo assembly is 105×1.×0.5cm. Then, the bamboo assembly is pre-treated, that is, each bamboo assembly is first placed in a 2% potassium hydroxide (KOH) solution, and then steamed at 100℃ for 30 minutes, and then dried in an oven at 80℃ to a constant weight state. Then, the treated bamboo assembly is glued with a glue to produce an original board 2. The gluing method of the original board 2 will be described in detail below.
