Abstract

The utility model discloses a composition of simulating precious wood, which is laminated with several layers of veneers (1) made of ordinary wood, and dyed into various patterns according to the texture and color of the precious wood species to be imitated. Required color or no dyeing, arranged and combined, so that the veneers (1) are parallel or bent into various shapes in the wood to imitate the wood grain of the precious wood, and the veneers (1) are bonded with the adhesive (2). The thickness of the board is generally 0.3-0.8mm, and the veneer used for a finished product is between 200-2000 layers. The utility model imitates natural precious wood with relatively cheap common wood veneers, which not only solves the contradiction between the supply and demand shortage of natural precious wood, but also reduces the production cost, and the benefit is remarkable.

Description

simulated precious wood

technical field

The utility model belongs to the technical field of wood processing.

Background technique

In the prior art, there is a kind of laminated veneer lumber (LVL), which is a structural material formed by laminating and gluing multi-layer thick veneers parallel to the grain, and is often used to replace solid wood as beams, columns, Truss and other building material components as well as vehicles, doors and windows, frames, sleepers, etc., the thickness of the veneer is generally 2-5mm, see "Wood Industry" 2002 No. 6 "Creep and resistance of poplar laminated veneer lumber with different structures Bending performance", "International Wood Industry", No. 6, 2002, "LVL of Ailanthus wood manufacturing [Journal, English]". The technical defect is that it cannot imitate the texture and color of precious wood, and can only be used as ordinary structural materials. Now there is also a kind of dyed veneer, which is to choose the natural wood of appropriate tree species, slice it into thin wood of 0.1-0.5mm, and then dye it to imitate natural precious wood, such as dyed black walnut thin wood, which is used to make veneers. This technical defect The first is that the simulation effect is quite different from the natural precious wood, and the second is that the price of the wood itself that is generally used for imitation is also higher; the third is that it can only be used as a veneer generally, and the scope of use is narrow, and the variety is relatively single.

Utility model content

The utility model aims to solve the above problems and provide a kind of simulated precious wood with good simulation effect, various varieties and wide application.

The technical scheme of the utility model is: several layers of veneers made of ordinary wood are stacked together, and according to the texture and color of the precious wood species to be imitated, they are dyed into various required colors or not dyed, arranged and combined, Make the veneers parallel or bend into various shapes in the wood to imitate the wood grain of precious wood. Adhesives are used to bond the veneers. Between 2000 layers. The timber can be a cuboid with a length of 2200-2600mm, a width of 600-800mm and a height of 300-800mm. The precious wood species imitated can be red cherry, black walnut, teak, tree burl and many other varieties. The veneer used is ordinary wood rotary-cut veneer, or the sliced veneer of artificial wood is used for the second billet assembly. The adhesive used can be urea-formaldehyde resin glue, melamine glue, polyvinyl acetate glue or their mixed glue, and it can be adjusted into various colors as required. The veneer is parallel or bent into various shapes in the wood, which can be realized by veneer assembly and mold pressing. Compared with the prior art, the utility model has the following advantages: common wood varieties are selected according to the material texture and color of the simulated precious wood, and the veneers are dyed into required colors. The adhesive can also be toned, and through veneer assembly and refined molds, it can be imitated into a simulated precious wood that is the same as or very similar to natural precious wood, and the simulation effect is good. And can imitate many kinds of natural precious wood; the size of the simulated precious wood cuboid can be adjusted according to the needs of length, width and height, and can be used for sliced thin wood to make simulated precious wood veneer panels, and can be sawn into boards for simulated precious wooden doors and wooden moldings , furniture, wooden floors, etc.

The utility model imitates the natural precious wood with cheap common wood and the veneer, which not only solves the contradiction between the supply and demand shortage of the natural precious wood, but also reduces the production cost, and the benefit is remarkable.

Detailed ways

Below in conjunction with accompanying drawing 1 embodiment is illustrated: several layers of veneers 1 made of common wood are stacked together, and according to the texture and color of the precious wood species to be imitated, they need to be dyed into various required colors or not dyed. , arranged and combined, so that the veneers are parallel in the wood or bent into various shapes to imitate the wood grain of precious wood. Adhesive 2 is used to bond the veneers. The thickness of the veneers is generally 0.3-0.8mm. The veneer is between 200-2000 layers.

Embodiment 1: Combined with Fig. 2, simulate the precious wood black walnut. The wood of the veneer 1 is Ayus, the thickness of the veneer is 0.8mm, and it is dyed brown-black with a little purple. The adhesive 2 is adjusted to dark black with urea-formaldehyde resin. The veneer 1 forms a mountain grain curved surface shape in the wood.

Embodiment 2: In combination with Fig. 3, simulate the precious wood red cherry. The veneer 1 is made of poplar wood, and the adhesive 2 is made of melamine-modified urea-formaldehyde glue, which is adjusted to reddish brown. The thickness of the veneer is 0.6mm, and it is dyed cherry light red. The veneer 1 is oblique and nearly parallel in the wood.

Embodiment 3: Combining with Figure 4, pink and white cat's eye tree burl. The veneer 1 is made of poplar wood, the thickness of the veneer is 0.3mm, bleached and not stained. Adhesive 2 is made of environment-friendly urea-formaldehyde resin glue, which is adjusted to beige. The veneer 1 forms complex protrusions and concave surfaces in the wood, and is formed by pressing with a mold.
