Problems solved by technology

However, due to the limitations of its raw materials, such as the uneven thickness of the branch wood and severe bending, the recombined wood blanks that are mixed and stacked together to press the branch wood often result in uneven board density, many holes or even Poor Gluing Defects

Embodiment 1

[0020] The production method of the recombined wooden floor mixed with branch wood and bamboo wood, its steps are as follows:

[0021] 1. Prepare raw materials: Cut the branch wood into a fixed length, such as 1.95m, put it into a rolling machine (the rolling machine is specifically a kind of branch wood crushing and crushing device) for crushing and rolling, and flatten the branch wood. , Rotate the fast-growing poplar and camphor wood into 1.5mm-2.0mm, cut into strip-shaped or sheet-shaped units with a width of 5mm-150mm and a length of 1.95m;

[0022] 2. Drying: Dry the rolled branch wood and wood chips obtained by rotary cutting. The drying temperature is 40-60°C, and the moisture content after drying is 10-16%;

[0023] 3. Ultra-high temperature thermal modification: Put the pre-dried poplar wood chips and rolled twigs into the carbonization treatment equipment, raise the temperature to 80°C at a speed of 8°C / min and keep it warm for 2-3 hours, and then heat it at 10°C R...

Abstract

The invention discloses a recombination wood blank made through pressing after branch wood and bamboo canes or wood chips are mixed according to a certain ratio. By means of the advantages that the bamboo canes or wood chips are uniform in thickness and good in straightness, when the bamboo canes or wood chips and the branch wood are mixed to be pressed, a good buffer effect can be achieved, and the defect that branch recombination wood is nonuniform in density is relieved. Main raw materials adopted in the invention are low-grade leftover or waste materials, waste is utilized, and energy conservation and environment friendliness are achieved. The recombination wood (bamboo) blank made by mixing the branch wood and bamboo-wood according to the preparation method is excellent in performance and has the superior static bending intensity, internal bonding strength, thickness swelling rate of water absorption and various main quality performance indexes compared with unimproved pure branch laminated wood. A branch wood blank board mixed with bamboo-wood sheets keeps high strength, has attractive texture of a pith section cutting plane, is comparable with natural wood, is harder and more durable than common natural wood, and can be predicted to have broad market prospects.

Description

technical field [0001] The invention relates to a recombined wood blank mixed with twig wood and bamboo wood and a preparation method, belonging to the field of bamboo wood processing. Background technique [0002] Bamboo-wood composite materials refer to composite boards or squares made of bamboo and wood combined and glued in the same or different structural units. It has various forms, such as bamboo-wood composite plywood, bamboo-wood composite laminated lumber, Bamboo-wood composite particleboard and medium-density fiberboard, directional bamboo strips, etc. From the perspective of material classification, it is mainly divided into two categories: structural bamboo-wood composite materials and functional bamboo-wood composite materials. Among them, structural bamboo-wood composite materials are mainly used for engineering structural parts; functional bamboo-wood composite materials are mainly used for decoration and furniture production. Reconstituted twig wood is a n...
