Problems solved by technology

Most of the common core boards are tightly composited by wood chips. There is no gap in the middle of the wood chips, and the amount of wood occupied is relatively large; wooden composite core boards are prone to warping, bulges or depressions during use, which is not economical and practical; for Therefore, we propose a composite hollow bamboo core board and its preparation method

Abstract

The invention provides a composite hollow bamboo core board and a preparation method thereof.The hollow composite bamboo core board comprises a frame board and bamboo poles, the length of the frame board is the same as that of the bamboo poles, the multiple bamboo poles are placed in the frame board, the bamboo poles are clamped and fixed together through filler, and the bamboo poles and the frame board are clamped and fixed together through filler. The bamboo poles are clamped and fixed in the frame plates through the filler, then the composite hollow bamboo core plates with different thicknesses are transversely cut according to the needed thickness of the core plate, the middle portions of the bamboo poles are hollow, materials are saved, and meanwhile the requirement for the strength of the core plate can be met. Meanwhile, edge warping, bulging or sinking of the wooden composite core board in the using process is avoided, and the wood composite core board is suitable for being used and popularized.

Description

Technical field [0001] The present invention relates to the field of composite plates, in particular to a composite hollow bamboo core plate and a method for preparing it. Background [0002] Core board is a professional term for wood-based board, and core board is also known as medium plate and short plate. The core plate mainly plays the role of fixing support and can be applied to the floor and the middle of the door. Most of the common core boards are tightly composited by wood chips, there is no gap in the middle of the wood chips, and the amount of wood occupied is larger; the wooden composite core board is prone to warping, bulging or depression in the process of use, which is not economical and practical enough; for this reason, we propose a composite hollow bamboo core board and its preparation method. Contents of the Invention [0003] To achieve the above object, the technical solution taken by the present invention is: a hollow composite bamboo core board, comprising...
