Abstract

PROBLEM TO BE SOLVED: To express a woodgrain with a cubic sense like a summerwood of a natural precious wood by repeatedly adhesively laminating plural times a resin-impregnated sheet having a resin content of a specific range and a resin-impregnated sheet having a specific impregnation rate more than that of the previous sheet in this order to obtain a flitch, and slicing it in a direction intersecting with their laminating surface. SOLUTION: A woody veneer equivalent to a springwood, a low resin-impregnated sheet having a resin content of 30 to less than 70% and a high resin-impregnated sheet having a resin content of 70 to less than 100% are adhesively laminated many times in this order to manufacture a flitch. This flitch is thinly sliced in a direction intersecting with their laminating surface to form an artificial decorative veneer. In this veneer, an opague springwood A, transfer parts B, C, D from the springwood to a summerwood, a summerwood E having a high transparency, and transfer parts F, G, H from the summerwood to the springwood are sequentially arranged in this order in a lateral direction. Thus, a substrate decorative plate base material can be seen through the transfer parts having low transparency and the summerwood having the high transparency. And, a woodgrain similar to a natural precious wood with a steric sense can be really expressed.

However, in recent years, natural precious wood resources have been depleted, and prices have risen accordingly. Therefore, instead of natural precious wood, relatively inexpensive and large-amount available wood, such as southern timber, has been replaced with a slicer or wood. Thin slices were obtained by rotary lace, bleached or bleached as necessary, and then dyed to resemble a natural precious wood.

However, relatively inexpensive and large quantities of timber, such as southern timber, have large or monotonous grain patterns, or most of them do not have a clear grain. It is far from aesthetic. Therefore, simply dyeing these veneers cannot create a high-quality feel like a natural precious wood. For this reason, recently, artificial veneers obtained by dyeing raw veneers made from these inexpensive wood, laminating and bonding them in the thickness direction to form flitches, and slicing them thinly in the direction intersecting the laminating surface are obtained. Veneer veneers have come into practical use.

[0006] The thickness of the veneer is set with reference to the grain of the natural precious wood to be expressed. In addition, veneers made of raw materials such as Nanyang lumber are usually bleached or dyed before dyeing in order to make the color tone of the natural veneer to be reproduced as close as possible and to keep the color tone of the veneer after dyeing within a certain range. It is common to bleach.

The present invention has solved the above-mentioned problems by the following method. In other words, in the laminated flitch for artificial wood veneer veneer in the conventional method, instead of the veneer veneer constituting the autumn wood part, it is fluidized by hot pressing at a high temperature of 110 ° C. or more, and the resin molecules are polymerized. An impregnated paper of a thermosetting resin (hereinafter, also simply referred to as a resin) which hardens and becomes transparent is used.

For example, DAP resin impregnated paper is made by impregnating DAP resin into kraft paper and is opaque at normal temperature, but becomes fluid when heated and pressed at a high temperature of 110 ° C. or more, and contains air contained in the resin impregnated paper. Is discharged, and the resin molecules polymerize and cure, and become transparent. The use of a resin that fluidizes, hardens, and becomes transparent at a temperature of 110 ° C. or higher is used when applying a normal wooden veneer or a veneer veneer according to the present invention to a veneer substrate such as a plywood or a fiberboard by hot pressing. This is because most of the adhesives used for curing start curing at a temperature of 100 to 110 ° C. and exhibit adhesive strength. Further, most of these adhesives are apt to be deteriorated by high heat when the temperature is 200 ° C. or higher. Therefore, the operating temperature range is approximately 110 to 200 ° C.

The procedure for obtaining the decorative board of the present invention will be described below. First, a wood veneer corresponding to a spring material portion and a resin-impregnated paper such as a dap resin are alternately laminated and adhered to obtain a flitch. Next, the flitch is sliced in a direction intersecting the lamination surface to obtain a decorative veneer. Then, the decorative veneer is bonded to a wooden decorative board base material such as plywood or fiberboard by hot pressing at 110 to 200 ° C. using a hot press. Then, the opaque resin-impregnated paper becomes transparent, and the base of the decorative board underneath can be seen through, so it is possible to express a transparent or translucent and three-dimensional grain like the autumn wood part of a natural precious tree such as pine. Can be. In addition, when the base material is a wooden base material, the pressure at the time of the heat pressing is the same as that used in the manufacture of a normal wood decorative board.
1515 kg / cm 2 is appropriate. If the pressure is too high, in the case of a wooden substrate, the thickness may be reduced due to heat pressure.

The degree of transparency of the resin-impregnated paper can be adjusted by the resin impregnation rate. That is, the higher the resin impregnation rate, the higher the degree of transparency increases, and the lower the resin impregnation rate, the lower the degree of transparency. For normal wood,
There is a transition between the spring wood part and the autumn wood part, which exhibits an intermediate color between the two. Therefore, using a resin impregnated paper with a high impregnation rate,
In addition to expressing the autumn wood part of the wooden veneer veneer, it is also possible to use a resin-impregnated paper with a low impregnation rate to express the transition part existing between the spring wood part and the autumn wood part. By expressing this transition portion, an artificial veneer veneer similar to a natural precious wood can be manufactured more realistically.

That is, a wood veneer corresponding to a spring material portion, a resin-impregnated paper having a low impregnation rate, and a resin-impregnated paper having a high impregnation rate are laminated and bonded many times in this order to produce a flitch. Slice thinly in the direction crossing the plane to obtain an artificial veneer veneer. As shown in FIG. 1, the artificial veneer veneer thus obtained has an opaque spring material portion A, transition portions B, C, and D from the spring material portion to the autumn material portion, a highly transparent autumn material portion E, and an autumn material. The transitions F, G, H from the section to the spring wood section are arranged in this order in the width direction. The transition portion with low transparency and the autumn material portion with high transparency can see through the base material of the base plate, so that a three-dimensional effect can be felt and a grain pattern very similar to a natural precious wood can be realistically expressed.

In the present invention, a resin-impregnated paper having a high resin impregnation rate is defined as 70% or more and 100% or more based on the weight of the paper.
The resin-impregnated paper impregnated with a resin having a low resin impregnating rate is a resin impregnated with a resin having a weight of 30% or more and less than 70%. Although it is possible to impregnate the resin with 100% or more, it not only increases the cost,
There is no need to increase the transparency further. When the resin impregnation rate is 30% or less, the resin is hardly transparent even when hot-pressed.

The transition between the spring lumber and the autumn lumber in the natural precious wood gradually approaches the dark autumn lumber color as it approaches the autumn lumber. When it is intended to express the above, as shown in the following examples, it is desirable to form the transition portion using a resin-impregnated paper having a low resin impregnation rate. Further, since the degree of transparency of the resin-impregnated paper can be adjusted by increasing / decreasing the resin-impregnation rate, the color tone of the transition portion is gradually darkened by using two or three types of resin-impregnated paper having the resin impregnation rate stepwise increased. It is possible to approach the color of autumn wood, and it is possible to manufacture a decorative board with a grain pattern similar to a natural precious wood.
