A green bamboo-wood composite board and its processing technology

Abstract

The invention discloses a greenness-reserved bamboo-wood composite board. The greenness-reserved bamboo-wood composite board is of a single-face structure or a double-face structure. Each single-face structure is formed by bonding a greenness-reserved bamboo board and a refined wood board with glue. Each double-face structure is formed by bonding two greenness-reserved bamboo boards and a refined wood board with glue, wherein the refined wood board is arranged between the two greenness-reserved bamboo boards. The outer surface of each greenness-reserved bamboo board is a bamboo greenness face, and a layer of natural bamboo greenness is maintained on each bamboo greenness face. The greenness-reserved bamboo-wood composite board maintains original high hardness, high strength, good wear resistance and good corrosion resistance of the greenness-reserved bamboo board(s), and bamboo greenness of the greenness-reserved bamboo board(s) is reserved. The invention further discloses a processing technology of the greenness-reserved bamboo-wood composite board. The processing technology comprises the steps of selecting materials, conducting sawing-off, removing outer joints, removing inner joints, forming openings, conducting softening, conducting flattening, removing yellowness with the thickness fixed, conducting cooling for shaping, conducting drying at the low temperature, bonding the greenness-reserved bamboo board(s) with the refined wood board to form a greenness-reserved bamboo-wood composite board unit, conducting splicing, and bonding the greenness-reserved bamboo-wood composite board units to form the greenness-reserved bamboo-wood composite board. In the processing technological process, moso bamboo is softened, and no pollution is generated; in the drying process, the greenness-reserved bamboo boards are not deformed or cracked; and each bamboo greenness face maintains high hardness, flatness and smoothness.

Description

technical field

[0001] The invention relates to a composite board and its processing field, in particular to a green bamboo wood composite board and its processing technology. Background technique

[0002] There is a shortage of wood resources in our country, but the bamboo resources in the southern provinces are very rich, and they are renewable and high-quality resources. They can be harvested and utilized in 3-5 years, and they are renewable and environmentally friendly. Bamboo-wood composite panels provide broad development prospects for vigorously developing bamboo and saving wood. However, the surface of the general bamboo-wood composite board does not retain the natural bamboo green, and there is no unique texture of bamboo green, so it is difficult to meet the needs of different aesthetic tastes, and the hardness of the bamboo-wood composite board without the bamboo green cannot maintain the bamboo-wood composite board with the bamboo green The original high hardnes...
