Problems solved by technology

[0002] At present, multi-layer solid wood composite flooring is used in various places, because it has the characteristics of environmental protection, not easy to deform, good viewing effect, long service life, relatively cheap price, etc., and is widely accepted by people. Most of the core boards are made of fast-growing materials, such as poplar, pine, fir, eucalyptus or density board, etc. However, the surface layer of the current high-grade solid wood composite flooring is mostly made of valuable hardwoods, such as oak, teak and walnut; in order to save expensive For the use of hardwood, the surface board is generally not more than 5mm thick; when the walking layer of solid wood composite flooring is thinner, the surface board is thicker than the core board, and the material of the core board is softwood relative to the surface board, so when using During the process, the surface board will appear degumming and wave phenomenon, especially in the environment with relatively large humidity changes

Embodiment Construction

[0031] see figure 1 , figure 2 , image 3 , wherein, the surface solid wood board 1 is 0.3mm-4mm thick hard wood, such as oak or walnut or teak or merbau or balsam or jatoba or birch or maple or elm or southwest birch or hard maple Wood and other hard woods; the glue-coated veneer 2 is soft woods of 0.5-3mm, such as soft woods such as pine or eucalyptus or poplar or eucalyptus; the core board 3 is made of soft woods of 1-30mm, For example soft woods such as pine or eucalyptus or poplar or eucalyptus are processed into the wooden strip 7 splicing composition of same thickness; Glue-coated veneer thickness must be less than the thickness of core board 3; A layer of relatively thin glued veneer 2 is added between the thinner surface boards 1, which can effectively solve the degumming and wave phenomenon of the surface boards. The back board 4 is soft wood of 1mm-3mm, such as pine or eucalyptus Wood or soft wood such as poplar or eucalyptus; the wood fiber directions of the su...

Abstract

The present invention relates to one kind of five-layer thick-core wooden floor board and its making process. The five-layer thick-core wooden floor board includes one surface wood layer, one gummed sheet layer, one core layer, one other gummed sheet layer and one back layer adhered together successively. The making process of the five-layer thick-core wooden floor board includes the following steps: making surface wood board, making core layer board, making gummed sheet, making back board, combination and pressing, splitting and balancing, and forming. The five-layer thick-core wooden floor board of the present invention has the advantages of less deformation caused by environment temperature and humidity, reduced surface wood layer thickness resulting in saving in high quality wood, and raised adhesion strength and high stability.
