Problems solved by technology

[0012] The object of the present invention is to provide a locking multi-layer solid wood composite floor and its preparation method. The composite floor solves the problem of the release of free formaldehyde, a harmful substance in the existing solid wood composite floor, and the problem of the release of free formaldehyde in each layer after a period of use. The problem of glue separation and delamination of the boards also solves the problems of the existing multi-layer solid wood composite floor paving with large gaps, large height differences in assembly, serious warping and deformation, and the renovation and reuse of the floor after a period of use

Embodiment 1

[0043] 1) American red oak wood veneer was selected as the surface veneer. First, red oak logs were cooked and softened, then sliced ​​into veneers with a thickness of 2.3mm, and then naturally air-dried to a moisture content of 7%. Among the high-quality red oak veneers, choose the veneer without decay, insect eyes, cracks, dead knots and other defects, and with small color deviation as the floor surface veneer;

[0044] 2) Selecting Eucalyptus urophylla veneer wood as the base material, steaming and softening the logs of Eucalyptus urophylla, and then rotary-cutting the Eucalyptus urophylla veneer, and drying to a moisture content of 7%;

[0045] 3) Double-sided sanding of the dried Eucalyptus urophylla veneer, according to the vertical formation method of the veneer texture of the adjacent layer, using an environmentally friendly high water resistance formaldehyde-free adhesive without adding formaldehyde, and the amount of glue applied is 280g / m 2 , under the gluing proc...

Embodiment 2

[0052] 1) Merbau wood veneer is selected as the surface veneer for multi-layer solid wood composite flooring. First, the wood section of merbau log is steamed and softened, and then sliced ​​into veneers with a thickness of 3.3mm, and then air-dried to moisture 7%; from the dried merbau veneer, select the veneer without decay, insect eyes, cracks, dead knots and other defects, and with small color deviation as the floor surface veneer;

[0053] 2) Selecting Eucalyptus urophylla veneer wood as the base material, steaming and softening the logs of Eucalyptus urophylla, and then rotary-cutting the Eucalyptus urophylla veneer, and drying to a moisture content of 7%;

[0054] 3) Double-sided sanding of the dried Eucalyptus urophylla veneer, according to the vertical formation method of the veneer texture of the adjacent layer, using an environmentally friendly high water resistance formaldehyde-free adhesive without adding formaldehyde, and the amount of glue applied is 280g / m2, u...

Embodiment 3

[0061] 1) The jatoba wood veneer is selected as the surface veneer for multi-layer solid wood composite flooring. Firstly, the jatoba log segments are steamed and softened, then sliced ​​into veneers with a thickness of 2.3mm, and then air-dried to a moisture content of 7 %; From the dried jatoba veneer, select a veneer without decay, insect eyes, cracks, dead knots and other defects, and with less color deviation as the floor surface veneer;

[0062] 2) Eucalyptus urophylla was selected as the base material veneer wood, and the logs of Eucalyptus urophylla were cooked and softened, and then the veneer of Eucalyptus urophylla was peeled and dried to a moisture content of 7%;

[0063] 3) Double-sided sanding is carried out on the dried giant eucalyptus veneer. According to the vertical formation method of the veneer texture of the adjacent layer, the formaldehyde-free environmentally friendly and high water-resistant formaldehyde-free adhesive is used. The amount of glue applied...

Abstract

The invention discloses a locking multi-layer solid wood composite floor and a preparation method thereof. The locking multi-layer solid wood composite floor comprises a floor body (1), a tenon (2) and a mortise (3) matched with the tenon (2) in shape. The floor body (1) comprises a wearing layer (11), a wood panel (12) and a base material layer (13), wherein double-face sanding is conducted on the wood panel (12) and the base material layer (13). According to the locking multi-layer solid wood composite floor and the preparation method thereof, the problems that hazardous substance-free formaldehyde is released by an existing solid wood composite floor and glue failures and layering of all layers of veneer occur after the board is used for a period of time are solved; and the problems that the existing multi-layer solid wood composite floor has a large mat formation gap, big assembly height differences and serious buckling deformation and needs to be renovated to be used again after being used for a period of time are also solved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a locking multi-layer solid wood composite floor and a preparation method thereof. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people have higher and higher requirements for the decoration effect and environmental protection performance of the living room. Due to the natural texture of wood on the surface of solid wood flooring and the incomparable high dimensional stability of solid wood flooring, the production and sales of solid wood composite flooring have gradually increased in recent years. In 2015, the output of solid wood composite flooring reached 95.5 million square meters, while solid wood flooring Only 39.9 million square meters. [0003] Since solid wood composite flooring is a mid-to-high-end floor, its price is relatively high, and it accounts for a large proportion of the cost of ro...
