Description

[Detailed description of the invention]

The present invention relates to a method for producing an artificially decorated veneer, and an object of the present invention is to provide a method for producing an artificially decorated veneer that can reproduce a Jiacaranda style wood grain pattern in which a grain pattern area and a straight grain pattern area intersect on the wood surface. purpose. An overview of this invention is shown in FIGS. 1A to 1L. That is, the manufacturing method of this artificial decorative veneer consists of laminating a plurality of material veneers 1 as shown in FIG. 1A with an adhesive as shown in FIG. (This is done using the concave-convex mold 2) to obtain a primary assembled fritch 3, and as shown in FIG. The cut layer is exposed as a wood grain layer on the wood surface to form a primary composite veneer 4 as shown in Figure D. After dyeing and drying this primary composite veneer 4, it is uneven as shown in Figure E. The secondary assembled fritches 6 are laminated on the mold 5 via an adhesive and bonded by pressure to form an uneven structure, and the secondary assembled fritches 6 are sliced from the direction intersecting the laminated surface as shown in Figure F. Then, the cut surface of each of the primary composite veneers 4 is exposed as a board-like grain layer on the material surface to form a secondary composite veneer 7 as shown in Figure G, and this secondary composite veneer 7 As shown in FIG.
A pressing surface 8 corresponding to the printing processing areas 7a and 7b of
The secondary composite mold 8 as shown in Fig. J is applied via adhesive onto another uneven mold 8 as shown in Fig. The veneers 7... are laminated and pressure bonded to obtain a tertiary assembly fritch 9 with uneven deformation, and this tertiary assembly fritch 9 is sliced from the direction intersecting the laminated surface as shown in Fig. K. As shown in Figure L, by cutting the secondary composite veneer 7, a plurality of pattern areas in which the wood grain patterns of the primary composite veneer 4 are combined are divided and displayed on the material surface in a board-grained or straight-grained manner. Artificial decorative veneer 10
This is what you get. In this way, the secondary composite veneer 7 with a grain pattern having a multicolored appearance obtained by repeating the process of laminated fritsch molding → slicing twice is combined with the concave-convex mold 5 in the secondary laminated flitch forming process and the clamping surface. The tertiary assembled fritches 9 are obtained by laminating and press-bonding on the uneven molds 8 having completely different uneven shapes, and the tertiary assembled fritches 9 are sliced to obtain the artificial decorative veneer 10. The material surface of the artificial decorative veneer 10 from which the cut layer of the board 7 is obtained is formed into a plurality of grain-like or straight-grain regions 10a, 10 by the uneven deformation by the uneven mold 8.
b, ..., 10e, and each area 10a, 10 is a cut layer of the secondary composite veneer 7.
In b, ..., 10e, a board pattern or a straight grain pattern due to the uneven deformation of the secondary assembled fritsch 6 appears, and the overall pattern closely resembles natural jacaranda in which the board pattern area and the straight grain pattern area intersect. Wood grain patterns can be reproduced. Moreover, each segmented area 10a, 10b, ..., 1
Since 0e is composed of the secondary composite veneer 7 with a high degree of compositeness of the raw material veneer 1 after going through the process of assembling and slicing twice, it is possible to further increase the natural feeling due to its multicolored appearance. Furthermore, since the artificial decorative veneer 10 finally obtained undergoes the process of lamination slicing and fritting three times, the degree of compositeness of the material veneer 1 is extremely high, and the strength of the veneer is greatly improved. Not only this, but also the defects present in a part of the raw material veneer 1 are obscured by the high degree of compositeness, which also improves the utilization yield of the raw material. Note that some areas 7a on the surface of the secondary composite veneer 7,
By subjecting 7b to a printing process before forming the tertiary laminated fritsch 9, areas 10a, 10b, ..., 10e are divided and exposed on the material surface of the artificial decorative veneer 10.
The boundaries of each area can be highlighted, 10
