た。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing decorative veneers. Conventionally, in this type of manufacturing method, as shown in FIG.
A known method is to mix a brightening agent into the wood, but this method gives shine to both the summer wood and spring wood, and it is not possible to express the clear summer wood, so it is difficult to make wide It could not be used to express summer wood.
そこで、この発明の目的とするところは、広幅

スライスして化粧単板７を得るものである。 An embodiment of the present invention will be described based on FIGS. 1A to 1G. That is, as shown in FIGS. 1 A to G, the method for manufacturing this decorative veneer involves applying an adhesive 2 onto a material veneer 1 for expressing the spring material, and impregnating the upper surface with polyethylene glycol methacrylate. The non-woven fabrics 3 for expressing the summer wood portion are layered and bonded with adhesive 2, and a plurality of the resulting composite veneers 4 are laminated in a mold 5 via adhesive and pressed and bonded. A frit assembly 6 is obtained, and the frit assembly 6 is sliced to obtain a decorative veneer 7.
また、広幅の夏材部に光沢を付与するために、
予め不織布３に光沢剤を混入しておく。 In addition, in order to add luster to the wide summer wood section,
A brightening agent is mixed into the nonwoven fabric 3 in advance.
つぎに、この実施例に基づく試験例をあげる。 Next, a test example based on this example will be given.

た。 Test example: 10 mils (approx.
After forming a nonwoven fabric of 0.254 mm), the nonwoven fabric is colored with an adhesive mixed with a brightening agent (a pearl agent made by adhering titanium to the surface of mica powder), and then colored with polyethylene glycol methacrylate (the color of the polyethylene glycol part). Polymerization degree: 350) and dried with hot air. On the other hand, after dyeing Agatis rotary veneer with a thickness of 1.0 mm to a predetermined spring material color, it is composited with the nonwoven fabric using an adhesive, and multiple sheets are stacked in a concave-convex mold and pressed and glued. By slicing this fritchi, a decorative veneer having a wide, glossy, and clear summer wood portion was obtained.

ことができるのである。そのため、夏材部表現の
ために使用可能な不織布の範囲が大幅に広がり、
材質等に制約されないという利点がある。 The polyethylene glycol methacrylate is impregnated into the nonwoven fabric 3, which has inferior light resistance compared to the material veneer 1, thereby reducing photofading of the nonwoven fabric 3 and imparting almost the same light resistance as the material veneer 1. It is something. Therefore, by impregnating the nonwoven fabric with such a light resistance imparting agent, the summer material part 9 (nonwoven fabric) will fade faster than the spring material part 8 (veneer material) as in the past, and the summer material part 9 will fade over time. This eliminates the problem of part 9 being too conspicuous and giving a sense of discomfort. As a result, the range of nonwoven fabrics that can be used to express summer materials has expanded significantly.
It has the advantage of not being restricted by materials, etc.
この化粧単板をカーボンアークによるフエード

色度合はほぼ同等であつた。 When this decorative veneer was subjected to a 48-hour accelerated fading test using a carbon arc fade-o-meter, the discoloration color difference ΔE of the spring wood portion was 7, while the discoloration color difference ΔE of the summer wood portion was 8.5. The degree of discoloration was almost the same for both.

抄造時に混入してもよい。 Note that a configuration may be adopted in which the nonwoven fabric 3 is not impregnated with this light resistance imparting agent. Further, the brightening agent may be mixed into the nonwoven fabric 3 during paper making.

る。 As described above, the method for manufacturing a decorative veneer of the present invention involves superimposing a nonwoven fabric mixed with a brightening agent for expressing summer wood on a material veneer for expressing spring wood, and bonding it with an adhesive. Multiple sheets of the resulting composite veneer are laminated in a mold using an adhesive, pressed and bonded to obtain a laminated fritchi, and by slicing this laminated fritchi, a wide and clear summer wood section is expressed. It is possible,
Moreover, gloss can be imparted to this summer wood portion. This has the effect that summer wood and spring wood that closely resemble natural wood can be expressed on the board surface.
