A new type of polymer veneer bamboo plywood

Abstract

The invention discloses a novel macromolecule veneer bamboo polywood. The novel macromolecule veneer bamboo polywood is formed by pressing bamboo mixed adhesives. The novel macromolecule veneer bamboo polywood comprises an upper plastic board, a lower plastic board and a wood layer located between the plastic boards and thermally molten with the plastic boards. The plastic boards include the upper plastic board and the lower plastic boards. The wood layer is formed by sequentially arranging bamboo chips in a criss-cross mode and pressing the bamboo chips through fixed adhesives; a padding area is formed in a gap with the size being 0.5-5 mm arranged at the contact position between the two bamboo chips, and the filling area is filled with a transverse overflow adhesive layer. According to the novel macromolecule veneer bamboo polywood, the density and mechanical strength are uniform, no separation layer appears, the structure is firm, the shear strength is high, the surface is smooth and not prone to water seepage, and the service life is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of bamboo board processing, in particular to a novel polymer veneer bamboo plywood. Background technique [0002] The existing plate has poor balance between strength, hardness, density and flatness, and has a low reuse rate. And the boards are mostly made of solid wood boards or wood core 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] In the existing industrial production, the internal bonding strength of the center of the particle board is relatively poor, which is a weak interface layer. According to the principle of mechanics, when the board is loaded, the center bears the largest shear force, so it is easier to break. [0004] And the surface of existing ...

AI Technical Summary

Problems solved by technology

[0003] In the existing industrial production, the internal bonding strength of the center of the particle board is poor, which is a weak interface layer. According to the principle of mechanics, when the board is loaded, the center bears the largest shear force, so it is easier to break

[0004] Moreover, the surface of the existing bamboo particleboard is prone to water seepage, and its structural strength will be greatly reduced after it enters the water, and its service life is shorter
