Description

Bamboo-wood composite board

Technical Field

The utility model relates to a bamboo board production technical field especially relates to a bamboo wood composite sheet.

Background

In the existing bamboo-wood composite board, during assembly, in order to improve the bonding strength between the bamboo chips, a wood veneer and the like are usually added between the two bamboo chips, but in the existing assembly process, the grain direction of the wood veneer is random, and a specific arrangement mode is not provided, so that the bonding strength between the wood veneer and the bamboo chips is unstable, particularly the bonding between the wood veneer and the green surface of the bamboo chips is realized, and particularly when the wood grain direction is vertical to the length direction of the bamboo chips, the bonding strength is very unstable, the overall stability of the bamboo-wood composite board is poor, and the use requirements of people in production and life cannot be met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defect of unstable bonding strength existing in the prior art and providing a bamboo-wood composite board.

In order to realize the purpose, the utility model adopts the following technical scheme:

a bamboo-wood composite board comprises bamboo chips and wood veneers, wherein the wood veneers are directly glued with green bamboo surfaces and yellow bamboo surfaces of the bamboo chips through glue, and the wood texture direction of the wood veneers directly glued with the green bamboo surfaces is consistent with the length direction of the bamboo chips.

Preferably, the bamboo sheet is formed into a glued surface by removing the green part of the green surface of the bamboo sheet.

Preferably, the wood veneer is formed by rotary cutting, slicing and sawing a log.

Preferably, the glue is a hot-setting type glue or a cold-setting type glue.

Preferably, the wood veneer is directly glued with the green surface and the yellow surface of the bamboo chip by glue by pressurizing, and the pressurizing is carried out at heating or normal temperature.

Preferably, the surface of the bamboo-wood composite board can be coated with films according to the requirement.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an at the in-process of bamboo panel processing, the wood veneer passes through glue and the direct looks veneer of the green face of bamboo chip, the bamboo yellow face, remains throughout unanimous with the length direction of the wood texture direction of the direct looks veneer of the green face of bamboo and bamboo chip for the veneer effect of the green face of bamboo chip and wood veneer is better, thereby very big promotion whole bamboo panel's intensity and stability, satisfied the user demand of people in production life.
