Abstract

The invention discloses a preparation process of a bamboo composite board. The preparation method comprises the following steps: (1) preparing bamboo powder; (2) preparing a treating fluid; (3) performing primary vacuum treatment; (4) performing vacuum secondary treatment; and (5) performing hot pressing; According to the method, the bamboo powder is subjected to vacuum treatment by adopting a treatment liquid a and a treatment liquid b respectively, the obvious purification effect on the bamboo powder can be achieved, the content of polar compounds such as friedelin, oleic acid, gamma-sitosterol, hexadecanoic acid and 2,3-dihydrobenzofuran in the bamboo powder is reduced through combination of two times of treatment, and the internal organization structure of the bamboo powder is greatlyimproved.

Description

technical field [0001] The invention belongs to the technical field of bamboo products, in particular to a preparation process of a bamboo composite board. Background technique [0002] The existing plate has poor balance between strength, hardness, density and flatness, and has a low reuse rate. And the planks are mostly made of solid wood boards or bamboo boards, which consume a lot of wood. Due to the use of a large amount of wooden boards, forest resources are even more scarce. The regeneration cycle of bamboo is relatively short, and its wood density and hydrophobicity are better than wood, so consider using bamboo boards instead of wood boards. [0003] Bamboo has a short growth cycle and strong renewability. In the process of production and use, it is environmentally friendly and is an important forest resource next to wood. In recent years, the wide use of bamboo has not only effectively alleviated the contradiction between wood supply and demand, but also promoted ...
