本発明は人工木目化粧単板の製造方法に関し、
その目的とするところは、天然木の木目模様に酷
似した木目柄の色変化を有する人工木目化粧単板
を得んとするところにある。[Detailed description of the invention] The present invention relates to a method for manufacturing artificial wood grain decorative veneer,
The objective is to obtain an artificial wood grain decorative veneer that has a color change in the grain pattern that closely resembles the grain pattern of natural wood.
従来、人工木目化粧単板の製造方法において、

た。 Conventionally, in the manufacturing method of artificial wood grain decorative veneer,
When trying to reproduce a desired wood grain pattern on the surface of a decorative veneer, it is necessary to dye the raw material veneer to see if there is no wood grain pattern between a pair of complementary male and female templates of the desired shape, or to dye the raw material veneer so that it is hardly noticeable. , without dyeing, laminated and press-bonded using only colored or colorless adhesive to create a veneer laminated fritchi, and then the fritchi was peeled off so that the adhesive layer had a wood grain pattern. .

た。 However, since the adhesive interposed between the raw material veneers is of a single color, the wood grain patterns unique to natural woods such as teak and rosewood can be expressed in places with wood grain patterns of different colors from other wood grain patterns. Not obtained, apparently,
It felt like a step up compared to natural wood. Furthermore,
Like the invention described in Japanese Patent Publication No. 35-15248,
There is a method for producing wood-grained boards in which white boards or boards of a different color from the former are polymerized and pasted together, these are alternately polymerized and pasted, and then they are sequentially cut into positions that are inclined to the polymerized adhesive surface. However, the wood grain boards obtained with this method simply express the wood grain pattern using boards of different colors, so the boundaries of the wood grain patterns appear too clearly, making it look artificial, and in extreme cases, it cannot be depicted in a picture. Therefore, it was impossible to manufacture a wood-grained board with a vague grain pattern like that of natural wood.
そこで、本発明では上記の木目模様の再現法を

である。 Therefore, in the present invention, we investigated a method for reproducing the above-mentioned wood grain pattern, and created a laminated veneer frit by laminating and press-bonding raw veneers using an adhesive between templates of a desired shape, and then gluing the frit. In the method of manufacturing artificial wood grain decorative veneers by stripping the adhesive layer to create a wood grain pattern, this problem was solved by partially varying the color of the adhesive layer between the laminated raw material veneers within the layer. be.
以下、本発明を更に詳細に説明する。 The present invention will be explained in more detail below.

本発明により得られる人工木目化粧単板を示す。 Fig. 1 shows a state in which raw veneers with partially different colors are inserted and assembled together using an adhesive to produce a laminated veneer fritsch, and Fig. 2 shows an artificial veneer obtained by the present invention. Showing wood grain decorative veneer.

きる。 1 is raw material veneer, which is obtained by peeling wood such as lauan, agathis, or ramin, which has no or almost invisible grain pattern. The thickness is approximately 0.5 to 2.0 mm, and it can be colored in any desired color by dyeing.

In the present invention, the adhesives 2, 2', 2"... with different colors refer to commonly used adhesives. A pigment or dye having a desired color is added to a room temperature curing type or thermosetting type wood adhesive such as urea resin adhesive, amino resin, or urethane resin.
なお、接着剤中に添加するこれらの顔料や染料

〜10％の範囲内で良い。 The amount of these pigments and dyes added to the adhesive is determined to approximate the desired grain pattern color of natural wood, but is generally 0.1% of the weight of the adhesive.
Good within ~10%.

ツダー、スプレー等にて塗布し、塗布量は50〜
150ｇ／m2程度で良い。 The adhesives 2, 2', 2'', etc. can be applied to each raw material veneer 1 using a double-sided spreader, single-sided spreader, spray, etc., and the applied amount is 50~
Approximately 150g/m2 is sufficient.

異なる接着剤２を３種類、４種類と塗布した原料
単板を適宜組み合わせて挿入する。 Thereafter, the raw material veneers 1 are combined and laminated between a pair of templates 3 so as to approximate a desired grain pattern of natural wood. For example, black grain patterns can be seen here and there in a single piece of teak, so if you want to manufacture something similar to this, you can add black in the adhesive to the required places on the raw material veneer 1 to be laminated. A veneer coated with adhesive 2 mixed with pigments, dyes, etc. is inserted. Of course, if the wood grain pattern is more complicated, raw material veneers coated with three or four types of adhesives 2 of different colors may be inserted in appropriate combinations at required locations in the raw material veneers 1 to be laminated.
原料単板１の積層枚数は、通常100〜1000枚程
度で、圧締条件は10〜50Kg／cm2の圧力で２〜12時
間程度圧締する。 The number of stacked raw material veneers 1 is usually about 100 to 1000 sheets, and the pressing conditions are 10 to 50 kg/cm 2 for about 2 to 12 hours.

る人工木目化粧単板４が得られる。 In the veneer laminated frits manufactured by the above method, an adhesive layer having a color different from that of the basic adhesive is formed in some places, and the coloring agent in the adhesive is used to create fine particles on the surface of the raw veneer. It has also penetrated into depressions and pipeworks, and the color of the adhesive layer varies from dark to light between raw veneers. Therefore, the desired artificial wood-grain decorative veneer 4 can be obtained by peeling the laminated veneer fritch to a thickness of about 0.2 to 2.0 mm using a peeling machine such as a slicer or a half rotary so that the adhesive layer has a wood grain pattern.

に酷似した木目模様を現出できる効果を奏する。 As described above, according to the present invention, when creating a laminated veneer frit by laminating and press-bonding raw material veneers, an adhesive having a color partially different from that of other layers is applied between raw material veneers. Since the raw material veneers are interposed in the required combination, the resulting artificial wood grain decorative veneer can express a wood grain pattern that differs in color from other wood grain patterns in some places, and has the appearance of a natural wood decorative veneer. In addition to having very similar wood grain patterns, the pigments and dyes in the adhesive penetrate into minute depressions on the surface of the veneer and into the pipework, causing the color of the adhesive layer to change from dark to dark between the veneers. The color changes in gradations, and the boundary between the adhesive layer and the veneer is vague, creating a wood grain pattern that closely resembles natural wood.
以下、本発明の実施例を述べる。 Examples of the present invention will be described below.

A veneer coated with 120-130g/ m2 of room-temperature-curing adhesive colored dark yellowish brown with pigment, and Agatis coated with 120-130g/ m2 of room-temperature-curing adhesive colored black with pigment. Prepare 50 veneers, and then combine them so that one veneer partially coated with black adhesive is placed on top of the veneer coated with dark brown adhesive, and placed between a pair of templates. It was laminated and pressed together.
After pressing at 25Kg/ m2 for 6 hours, the pressure is released to form a laminated veneer fritchi, the laminated surface of the fritchi is adjusted so that the desired wood grain pattern appears, and then it is peeled off using a slicer to the desired thickness of 0.4mm. An artificial wood grain decorative veneer with an appearance very similar to natural teak wood was obtained.
