Abstract

The invention relates to a bamboo board, in particular to a heavy bamboo composite board. The heavy bamboo composite board comprises a bamboo board surface board formed by arranging multiple bamboo fiber strips and conducting hot pressing on the bamboo fiber strips and a bamboo board bottom board arranged under the bamboo board surface board; the bamboo board surface board is provided with a body, surface board end faces, a pressed surface which is exposed to show a bamboo joint shape, a surface board bottom face arranged on the bamboo board bottom board and at least one surface board side face formed by 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 arranged to be opposite to the bottom board surface, bottom board side faces connected with the surface board side faces and bottom board end faces connected with the surface board end faces; the bamboo board bottom board is provided with more than one stress groove; a wood veneer or a bamboo filament or a bamboo bunch or a bamboo sheet or a flattened bamboo type wide-breadth bamboo board or a bamboo board bottom board formed by jointly curing first thermosetting resin and bamboo fiber strips is adopted as the bamboo board bottom board. The heavy bamboo composite 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 heavy bamboo composite 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 of th...
