Three-layer solid board

Abstract

The invention relates to the technical field of furniture materials, and discloses a three-layer solid board and a preparation method thereof. The three-layer solid board comprises an upper face plate, a core plate and a lower face plate which are sequentially in glue joint from top to bottom. The upper face plate and the lower face plate comprise a plurality of saw-cutting single plates. Bonding parts are arranged on the two sides of each single plate, and the single plates are in glue joint through the bonding parts to form the upper face plate and the lower face plate. The core plate is formed by splicing a plurality of saw-cutting wood strips. The three-layer solid board changes the limit that a traditional three-layer solid board can not be used as furniture materials. According to the produced three-layer solid board, the surface gaps of the face plates are small, glue lines are avoided, mechanical strength is high, the product structure is stable, dimension limits are avoided, splicing is of no need in practical using, using steps are saved, and using efficiency is improved. The three-layer solid board is very suitable for being used as furniture materials.

Description

technical field [0001] The invention relates to the technical field of furniture materials, in particular to a three-layer solid wood board. Background technique [0002] The current three-layer solid wood board generally belongs to the solid wood panel, which is a thin wood veneer made of narrow wood strips with small material specifications, glued together horizontally, and then pressed on the upper and lower sides of the hardwood for planing or rotary cutting. The existing three-layer solid wood panel has the following problems: (1) The veneer veneer on the upper and lower layers of the three-layer solid wood panel is formed by slicing or rotary cutting. On the one hand, the thickness of the veneer is limited, generally within 1mm. On the one hand, the fiber structure of the veneer is destroyed, and the mechanical strength is low; (2) There are gaps and glue lines on the surface of the veneer through gluing; (3) The general size is 20cm to 30cm, and it is difficult to mak...

Problems solved by technology

The existing three-layer solid wood panel has the following problems: (1) The veneer veneer on the upper and lower layers of the three-layer solid wood panel is formed by slicing or rotary cutting. On the one hand, the thickness of the veneer is limited, generally within 1mm. On the one hand, the fiber structure of the veneer is destroyed, and the mechanical strength is low; (2) There are gaps and glue lines on the surface of the veneer through gluing; (3) The general size is 20cm to 30cm, and it is difficult to make large (4) When using it, it is necessary to splice the solid wood panels together, the steps are cumbersome, the efficiency is low, and the structure is unstable

Therefore, this three-layer solid wood panel generally can only be used as a floor, it is difficult to be used as a furniture material, and needs to be improved.
