Embodiment 1

[0016] Using moso bamboo or clump bamboo as raw material, cut off, cut open, and remove knots from the felled moso bamboo or clump bamboo, soak or cook until the initial moisture content of the bamboo is above 50%.

[0017] On the roller press, the bamboo is subjected to longitudinal rolling treatment with a linear pressure of 100-500 N / mm and a rolling speed of 0.03-0.5 m / s. According to the cutting width of the bamboo, generally rolling 3 to 10 times can achieve the purpose that the bamboo is basically decomposed into bamboo bundles.

[0018] The water content of the bamboo bundles after each rolling will be reduced to below 30%, so it is necessary to inject water into the bamboo bundles that need to be rolled next time after each rolling treatment. Soak directly in normal temperature water or hot water, or use direct spraying to increase the moisture content to more than 50%.

[0019] The prepared bamboo bundles can keep the fibers not broken in the longitudinal direction,...

Embodiment 2

[0023] In order to obtain a better dyeing effect, conventional bleaching and carbonization treatment can be carried out to the bamboo bundles obtained after multiple times of water injection and rolling.

[0024] The bleached and charred bamboo bundles can be used directly for pressing boards to form natural bamboo hardwood. Pressing into slabs can also be done after bleaching or charring with a further dyeing treatment.

[0025] At the same time, the dyed and bleached or carbonized bamboo bundles can also be mixed to produce hardwood with unique color and texture.

[0026] The bamboo artificial hardwood made by the present invention has a similar density and texture to natural hardwood, and its anti-corrosion and anti-mildew properties are significantly improved compared with other bamboo boards, and can be used for high anti-corrosion and anti-mildew properties. It can also be used as furniture and interior building decoration materials, etc. It is a new type of natural env...

Abstract

A preparation method of artificial hardwood using bamboo wood as a raw materials. It is characterized by: rolling pressing the high moisture content bamboo wood many times water filling, linearly andvertically to preparing fibrous bamboo beam, drying the bamboo beam, then dyeing, tail-cutting, applying glue, organizing blank and pressing, the sheet material or square material can be produced which appearance and material nature are similar with hardwood. The bamboo man-made hardwood prepared through the invention besides has the similar density and texture with nature hardwood, its anticorrosive coating and fungus-proof property is enhanced markedly than other bamboo plate materials; it can be used outdoors and can be used as furniture and indoor architecture and decorative materials, itis a new natural environment-friendly material with good performance.

Description

1. Technical field [0001] The invention belongs to the wood-based panel manufacturing technology in the wood processing industry, and in particular relates to a method for making imitation precious hardwood by using bamboo. 2. Background technology [0002] With the sharp reduction of tropical rainforests worldwide, precious hard broad-leaved materials, such as red sandalwood, ebony, teak and other commercial materials in mahogany, are decreasing day by day, and the prices are becoming more and more expensive. The growth cycle of precious hard broad-leaved wood is more than 50 years, and some even last for hundreds of years. It is difficult to recover after felling. Countries around the world have successively adopted strict logging bans. Because precious hard broad-leaved wood is the main raw material for making precious solid wood furniture, with the improvement of living standards, the demand for precious hardwood has not decreased but increased. It also has an alternati...
