Abstract

PURPOSE:To obtain the above artificial decorative timber having grain similar to that of natural timber by superposing a plurality of colored veneers on one another through colored adhesives to which coloring agent has been added, slicing said veneers in a direction at certain angles to form a veneer for graining, applying said veneer to a plurality of spring veneers to form a flitch and slicing said flitch. CONSTITUTION:When colored veneers 2, which are prepared by coloring a decolored plate using dye, are superposed on one another to form a flitch for graining 7, they are bonded to each other through colored adhesives 1 to which coloring agent has been added. Next, the flitch 7 is sliced in a direction at certain angles to form a veneer 3 for graining. The veneer 3 is applied to a spring veneer 4 to form a composite veneer 8. A plurality of the veneers 8 are superposed on one another to form a flitch 5 under compressive forces, which are sliced to form an artificial decorative timber.

Apply coloring agent (dye) to. As a result, due to the difference in dyeability between the veneer part g' and the adhesive part h', the adhesive part h' is dyed more deeply than the veneer part g'. And this wood grain veneer j
is combined with a spring wood veneer C to form a composite veneer d similar to that in Fig. 2, a plurality of this composite veneer d is laminated with the intervention of an adhesive, and this is pressed and formed. An artificial precious wood f is formed by forming a flitch e and slicing this flitch e.

As shown in Fig. 21, it is possible to form a wood grain k with uneven color on a precious wood f due to the difference in the color of the wood grain expression material a and the ink b, but it is possible to form a wood grain k with uneven color due to the ink on the wood grain. Outer periphery: or along the inner green periphery, there is an inner group that is only expressed in a biased way (it is not possible to obtain anything similar to the natural 7 trees). In the case of manufactured artificial precious wood A, as shown in Fig. 3, it is possible to express the wood grain k with uneven color, which is very similar to the natural wood, but in the manufacturing process, the thin wood grain veneer 21 There is a problem in that even if dye is applied to the fabric, cracks may occur due to handling during dye application and drying, making it difficult to manufacture.

It was composited with a 2 mm spring wood veneer, and the same procedure as in the specific example of the present invention was carried out below. The product obtained in this way has the same wood grain as the specific example of the present invention, but there are many cracks during coloring of the 0.3 mm thin veneer, drying, and humidity conditioning, which is a defect in the process. The problem was that the rate was high.

Because of this, it can be colored in a thick state and then sliced thinly to form a wood grain veneer. It is easy to manufacture and can reduce the defect rate in the process without causing any damage.Furthermore, since the color unevenness is dispersed and formed on the wood grain veneer, the resulting artificial precious wood has no color unevenness in the wood grain. It is possible to obtain something that closely resembles natural wood.
