Five-layered thick core wood compound floor board and mfg. method thereof

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.

Description

technical field [0001] The invention relates to building decoration materials, in particular to a five-layer thick-core solid wood composite floor and a manufacturing method thereof. Background technique [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 m...

[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
