Abstract

The invention relates to a bamboo board, in particular to a multi-layer composite bamboo board. The multi-layer composite bamboo board comprises a bamboo board surface board and a bamboo board bottom board arranged below the bamboo board surface board, wherein the bamboo board surface board is formed in the manner that a plurality of bamboo fiber strips are arranged and then subjected to hot pressing. The bamboo board surface board is provided with a body, a surface board end face, a pressed surface naked so as to display the bamboo joint shape, a surface board bottom face arranged above the bamboo board bottom board and at least one surface board side face formed through cutting. The bottom board is provided with a bottom board surface connected with the bottom face of the bamboo board surface board, a bottom board bottom face opposite to the bottom board surface, bottom board side faces connected with the surface board side faces, and a bottom board end face connected with the surface board end face. The bamboo board surface board and / or the bamboo board bottom plate are / is internally provided with bamboo fiber strip woven curtains / a bamboo fiber strip woven curtain, wherein the bamboo fiber strip woven curtains / the bamboo fiber strip woven curtain are / is formed in the manner that the multiple bamboo fiber strips are subjected to thread sewing, thread weaving, adhesive tape bonding, hot melt adhesive tape bonding, bonding and splicing through a batten or non-woven fabric or paper slips, clamping through a clamping device or connecting and arranging through bamboo fiber strip connecting pieces. The multi-layer composite bamboo board is high in strength and processing efficiency and low in production cost.

Description

technical field [0001] The invention relates to a bamboo board, in particular to a multi-layer composite bamboo board. Background technique [0002] my country is a big country of bamboo, with a large output of bamboo, a long history of bamboo utilization, and abundant bamboo products. Bamboo has the advantages of good toughness and high strength, and is made into raw materials for indoor flooring, outdoor flooring and furniture in the market. However, bamboo contains a lot of sugar, protein, and rich content, so it is very vulnerable to the infringement and corrosion of bamboo rot fungi; the existence of lignin, hemicellulose and cellulose makes the dimensional stability of the recombined bamboo material poor. [0003] In order to solve the above technical problems, Chinese patent CN204876310U (2015-12-16) discloses a carbonized bamboo wood fiber and bamboo silk composite cement board. Applications need improvement. Contents of the invention [0004] One of the objects...
