Bamboo substrate, bamboo floor and manufacturing methods of bamboo substrate and bamboo floor

Abstract

The invention provides a bamboo substrate, a bamboo floor and manufacturing methods of the bamboo substrate and the bamboo floor. The bamboo substrate is provided with an upper surface and a lower surface in regular shapes, as well as flush end faces and side faces, or end faces and side faces with mortice structures. The bamboo substrate comprises at least one bamboo plate with a whole raw bamboo connected surface, and cracks of the bamboo plates are filled with bonding materials. One or more bamboo substrates and a panel are composited to form the bamboo floor. A utilization rate of raw materials is greatly increased, and compared with a bamboo veneer bonded by a plurality of small bamboo battens in the traditional technology, the stability of the bamboo substrate manufactured by one or more bamboo plates flattened entirely, and the bamboo floor composited by the bamboo substrate and the panel is better. Simultaneously, the invention provides the manufacturing methods of the bamboo substrate and the bamboo floor. Procedure steps in the traditional technology are decreased, the labor cost is lowered greatly, and the utilization rate of the raw materials reaches 80-85%.

Description

technical field [0001] The invention relates to a bamboo substrate, a bamboo floor and a manufacturing method thereof, belonging to the technical field of bamboo processing. Background technique [0002] Existing bamboo product floors or other furniture boards are usually made of tubular bamboo tubes. From the outside to the inside, the bamboo wall is composed of bamboo green, bamboo flesh and bamboo yellow. When making bamboo substrates, the bamboo is usually cut off first. Then in the length direction of the bamboo tube, it is divided into many pieces of bamboo strips, and its cross-section becomes arc-shaped. Therefore, the two ends of the arc-shaped bamboo strips will be cut off. It is not conducive to viscose to remove it. The bamboo yellow on the bottom of the bamboo strip is much denser than the middle layer of bamboo, and the board is easy to warp during processing. Therefore, the bottom bamboo yellow also needs to be removed; finally processed into a cross-section o...

[0002] Existing bamboo product floors or other furniture boards are usually made of tubular bamboo tubes. From the outside to the inside, the bamboo wall is composed of bamboo green, bamboo flesh and bamboo yellow. When making bamboo substrates, the bamboo is usually cut off first. Then in the length direction of the bamboo tube, it is divided into many pieces of bamboo strips, and its cross-section becomes arc-shaped. Therefore, the two ends of the arc-shaped bamboo strips will be cut off. It is not conducive to viscose to remove it. The bamboo yellow on the bottom of the bamboo strip is much denser than the middle layer of bamboo, and the board is easy to warp during processing. Therefore, the bottom bamboo yellow also needs to be removed; finally processed into a cross-section of Rectangular strips, multiple strips require adhesives to be spliced ​​into bamboo veneers. The above-mentioned traditional processing method "removing the head and pinching the tail" has caused waste of raw materials to a large extent. The inner and outer skins of bamboo are removed. After flattening the small bamboo strips, the utilization rate of bamboo is not high. When it is produced into floor or other furniture boards, it needs to be glued with multiple layers of bamboo veneers. Therefore, the process is complicated, there are many procedures, the labor cost is high, and the loss of raw materials is nearly 70%.
