Problems solved by technology

The common advantages of this type of board are high density, high strength, good dimensional stability, and high grade. However, although the products made purely of this type of board have good compressive strength and impact resistance, they are not easy to move along the direction of bamboo filaments. The upper force will make the product fragile

Embodiment 1

[0036] Such as figure 1Shown, a kind of glued bamboo board comprises upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are recombined bamboo boards, and the bamboo silk arrangement direction of described recombined bamboo boards and self board The surface is vertical; the density of the a kind of glued bamboo board is 1.5g / cm 3 , the water content is 8.0%, the 24-hour water absorption thickness expansion rate is 2.0%, the static bending strength is 120MPa, and the surface hardness is 90MPa. The bamboo filaments of the recombined bamboo board include carbonized and non-carbonized bamboo filaments, which form irregular patterns after hot pressing. The degree of carbonization of carbonized bamboo filaments is also different. The middle layer 2 is a three-layer bamboo flat-pressed plywood, and the direction of the bamboo filaments of two adjacent bamboo flat-pressed plywood is vertical.

[0037] The bamboo sheet flat-pressed plywood refers ...

Embodiment 2

[0048] Such as figure 2 Shown, a kind of glued bamboo board comprises upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are recombined bamboo boards, and the bamboo silk arrangement direction of described recombined bamboo boards and self board The surface is vertical; the density of the a kind of glued bamboo board is 1.4g / cm 3 , the water content is 8.0%, the 24-hour water absorption thickness expansion rate is 2.0%, the static bending strength is 120MPa, and the surface hardness is 90MPa. The bamboo filaments of the recombined bamboo board are all uncarbonized bamboo filaments. The middle layer 2 is bamboo side-pressed plywood.

[0049] The bamboo side-pressed plywood refers to cutting the moso bamboo into slices, removing the green and yellowing, and then making bamboo slices of predetermined specifications. The press is used for cold pressing or hot pressing.

[0050] The thickness of the recombined bamboo board is 7mm; the thick...

Embodiment 3

[0059] Such as image 3 Shown, a kind of glued bamboo board comprises upper layer 1, middle layer 2, lower layer 3; Described upper layer 1 and lower layer 3 are recombined bamboo boards, and the bamboo silk direction of described recombined bamboo boards and its own board surface vertical; the density of the a kind of glued bamboo board is 1.6g / cm 3 , the water content is 14.0%, the 24-hour water absorption thickness expansion rate is 2.0%, the static bending strength is 180MPa, and the surface hardness is 140MPa. The bamboo filaments of the recombined bamboo board are all non-carbonized bamboo filaments. The middle layer 2 is a two-layer bamboo flat-pressed plywood, and the direction of the bamboo filaments of the adjacent two-layer bamboo flat-pressed plywood is vertical. The thickness of the recombined bamboo board is 10mm; the single layer thickness of the two-layer bamboo plywood is 4mm.

[0060] Above-mentioned a kind of glued bamboo board is manufactured as follows:...

Abstract

The invention relates to a glued bamboo board and a preparation method thereof, in particular to a bamboo board prepared by gluing a restructured bamboo board and a bamboo chip glued board and belongs to the technical field of bamboo development and bamboo board processing. The glued bamboo board comprises an upper layer, a middle layer and a lower layer, wherein the upper layer and the lower layer are restructured bamboo boards; and the bamboo filament arrangement direction of the restructured bamboo boards is vertical to board faces per se. The glued bamboo board of the invention has the advantages of high surface finish, high density, high grade, high overall static bending strength, high compression strength, high impact strength, high surface hardness, low thickness swelling rate of water absorption and high size stability.

Description

technical field [0001] The invention relates to a glued bamboo board and a manufacturing method thereof, in particular to a bamboo board glued together with recombined bamboo boards and bamboo plywood, and belongs to the technical field of bamboo material development and bamboo board processing. Background technique [0002] Bamboo boards existing on the market are based on simple bamboo sheet plywood, which can be directly used for indoor and outdoor floors, and can be used as furniture manufacturing materials after veneering. The product that also has is to use this bamboo sheet plywood to glue with plank. For example, the Chinese utility model patent No. 200620104966.0 discloses a bamboo veneer composite board, which includes at least one upper layer, a middle layer, and a lower bottom layer. Each adjacent joint has an adhesive, and each adjacent The stitching seams of the layers are separated by 90°, the upper layer and the lower bottom layer are made of bamboo slices t...
