Anti-deformation solid wood composite board and processing method thereof

Abstract

The invention relates to an anti-deformation solid wood composite board and a processing method thereof. The solid wood composite board comprises a solid wood base layer and a surface layer. The solid wood composite board is characterized in that a plurality of transverse tenons are embedded into the solid wood base layer at intervals in the width direction of the solid wood base layer, balance tenon edges protruding outwards are arranged on the two sides of each tenon, a plurality of tenon grooves are formed in the solid wood base layer correspondingly, a certain distance is reserved between the inner bottom face of each tenon groove and the lower surface of the solid wood base layer, and the upper surface of each transverse tenon and the upper surface of the solid wood base layer are on the same plane. According to the anti-deformation solid wood composite board and the processing method thereof, in the using process, fibers in the solid wood base layer is cut off through the transverse tenons, therefore the solid wood base layer is prevented from contracting and deforming due to the changes of external environment, transverse and longitudinal tension is balanced through the transverse tenons, and therefore the solid wood base layer is not liable to crimp and deform. Because a processing method that grooving and keel adding are conducted on the upper face and the lower face of the same solid wood plate blank and the solid wood plate blank is sawed in half into two anti-deformation solid wood composite boards is adopted, the anti-deformability of the solid wood composite board is further ensured.

Description

technical field [0001] The invention relates to the field of floors and wood products, in particular to a deformation-resistant solid wood composite board and a processing method thereof. Background technique [0002] Nowadays, solid wood flooring is generally made of multi-layer solid wood glued together through layers of wood glue. Because of its advantages of environmental protection, comfort, durability, high-grade nature, etc., it has been widely used in home decoration. But as we all know, due to the fiber structure of the wood itself, solid wood flooring is easily deformed with the shrinkage of wood fibers when it encounters water or humid air, or when it expands with heat and contracts with cold. Now there are generally three effective ways to solve the deformation of solid wood flooring: the first one uses aluminum silk on the bottom of the floor to prevent moisture, but because the floor is wrapped in layers, it is difficult to distinguish good from bad.

But as we all know, due to the fiber structure of the wood itself, solid wood flooring is easy to deform with the shrinkage of wood fibers when it encounters water or humid air, or when it expands with heat and contracts with cold.

Now there are generally three effective ways to solve the deformation of solid wood flooring: the first one uses aluminum silk on the bottom of the floor to prevent moisture, but because the floor is wrapped in layers, it is difficult to distinguish good from bad. Elimination; the second type uses six-sided paint on the floor to prevent water vapor from invading the interior of the floor, which is extremely easy to deform after a long time; the third type is currently used more in the market, which is a three-layer solid wood board, with a set between the upper and lower surfaces. A number of wooden strips arranged along the length of the board are spliced ​​together with glue, which indeed prevents the floor from warping and deforming in the length direction. This method is not only labor-intensive, but also contains a large amount of formaldehyde in the glue, and the amount of wood glue will increase invisibly. formaldehyde content, causing indoor air pollution, and over time, it is still unable to overcome the shortcomings of wood floor shrinkage and warping in the width direction

[0003] In addition, most of the existing wooden floors have cumbersome processing procedures, low efficiency, unstable effects, and troubles for installation and use.
