この発明は、基板表面に人工銘木単板が貼着された化粧
板の製法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a decorative board in which a veneer of artificial precious wood is adhered to the surface of a substrate.
従来、人工銘木化粧板は、素材単板を脱色し、得られた
漂白単板を染色液に浸漬して染色し、この染色単板を積
層接着成型してフリッチを作り、このフリッチをスライ
スすることにより人工銘木単板を得、この人工銘木単板
を合板等の基板表面に貼着することにより得ていた。Conventionally, artificial precious wood decorative boards are made by bleaching the raw material veneer, dyeing the resulting bleached veneer by soaking it in a dye solution, laminating and adhesively molding the dyed veneer to create flitches, and slicing the flitches. By doing this, an artificial precious wood veneer was obtained, and this artificial precious wood veneer was attached to the surface of a substrate such as plywood.
この従来法には、つぎのような問題点があった■ 素材
単板を脱染色すると薬剤と処理温度の影響によって素材
単板の強度が30%以上劣化し、フリッチのスライス時
に人工銘木単板良品の歩溜りが低下する。This conventional method had the following problems: ■ When the raw material veneer was destained, the strength of the raw material veneer deteriorated by more than 30% due to the effects of the chemicals and treatment temperature, and when slicing the flitch, the artificial precious wood veneer was damaged. Yield of good products decreases.
■ 浸漬法による脱色では、主剤の過酸化水素が活性剤
のアルカリおよび素材単板の溶出分と反応して自己分解
するため、これによる薬剤のロスが大きい。■ In decolorization using the immersion method, hydrogen peroxide, the main agent, reacts with the alkali activator and the eluted portion of the veneer material and self-decomposes, resulting in a large loss of chemicals.
■ 浸漬法による染色では、素材の部位によって染料の
吸着性が変わり、染料の吸着量に差が発生するため、こ
れによって部分的に染色度のバラツキが生ずる。■ In dyeing by dipping, the adsorption of dye changes depending on the part of the material, resulting in differences in the amount of dye adsorption, which causes local variations in the degree of dyeing.
■ 浸漬法による脱染色では、多量の溶液中に木材中の
抽出成分が溶出したり、染料の選択吸着が行われ、溶液
を再使用することが困雌で、多量の廃液が発生する。■ In destaining by immersion, extracted components in the wood are eluted into a large amount of solution, and dyes are selectively adsorbed, making it difficult to reuse the solution and generating a large amount of waste liquid.
この発明は、上記従来の状況に鑑みて、人工銘木単板の
歩溜り向上、過酸化水素の自己分解ロスの防止、染料吸
着量のバラツキ低減、廃液量の削減を図り、製造コスト
の低減を図ることを目的とする。In view of the above-mentioned conventional situation, this invention aims to improve the yield of artificial precious wood veneers, prevent self-decomposition loss of hydrogen peroxide, reduce variation in the amount of dye adsorption, reduce the amount of waste liquid, and reduce manufacturing costs. The purpose is to
上記目的を達成するため、この発明は、基板表面に人工
銘木単板が貼着された化粧板を得るに当たり、素材木目
単板を基板に貼着したのち、素材木目単板に脱色液を塗
布して漂白し、それに染色液を塗布して人工銘木単板化
することを特徴とする化粧板の製法を要旨とする。以下
にこれを詳しく説明する。In order to achieve the above object, this invention applies a decolorizing liquid to the material wood grain veneer after adhering the material wood grain veneer to the substrate in order to obtain a decorative board in which an artificial precious wood veneer is pasted on the surface of the substrate. The gist of this paper is a method for manufacturing decorative laminates, which is characterized by bleaching the veneer, applying a dyeing solution to it, and making it into a veneer of artificial precious wood. This will be explained in detail below.
素材単板は原木を0.2〜2.0mmの厚みにスライス
して得る。これを、従来と異なり、直ちに積層接着成型
してフリッチにする。このフリッチをスライスすると、
木目を有する素材単板、すなわち素材木目単板が得られ
る。この素材木目単板を合板等の基板表面に貼着する。The material veneer is obtained by slicing raw wood into 0.2-2.0 mm thick pieces. Unlike conventional methods, this is immediately laminated and adhesive molded to form a flitch. When you slice this flitch,
A material veneer having wood grains, that is, a material wood grain veneer is obtained. This wood grain veneer is pasted onto the surface of a substrate such as plywood.
そして、その表面の素材木目単板にH2O2水溶液など
の脱色液を塗布して脱色する。H2O2水溶液などの塗
布に先立ってアルカリ水溶液を塗布し養生すると脱色能
率や脱色性が向上し好ましい。このようにして得られた
漂白木目単板貼り基板の漂白木目単板に染色液を塗布し
て染色する。そうすると、所望の大工銘木単板貼り化粧
板が得られるのである。Then, a decoloring liquid such as an aqueous H2O2 solution is applied to the wood grain veneer on the surface to decolorize it. It is preferable to apply and cure an alkaline aqueous solution prior to applying an aqueous H2O2 solution or the like, since this improves the decolorizing efficiency and decolorizing property. A dyeing liquid is applied to the bleached wood grain veneer of the thus obtained bleached wood grain veneer laminated substrate to dye it. In this way, you can obtain the desired decorative wood veneer made of carpenter's wood.

濃度が低く、再利用できないが、この発明では、上にみ
たように、高濃度液を塗布して脱染色するようにしてい
るため、廃液量を約30分の1と大巾に削減できる。As seen above, in this invention, the material wood grain veneer obtained by slicing a flitch made of a material veneer that has not been destained is attached to a substrate (plywood) that serves as a strength support, and then the material is destained. I try to do this. Therefore, veneer loss can be reduced to about one-third compared to conventional methods. The main agent hydrogen peroxide and the activator alkali that make up the decolorizing solution of the dipping method are separated, the concentration is increased to about 122 times, and the alkali and hydrogen peroxide are applied to the surface of the wood-grained veneer board in two stages. I try to apply it. Therefore, drug loss can be reduced to about one-third. The concentration of the dyeing solution was adjusted to 6 by the dipping method.
I raise the temperature by about twice as much and apply it to the surface of the bleached wood grain veneer board. Therefore, the variation in the degree of staining can be reduced by about 30%. In the conventional dipping method, the concentration of the treatment liquid is low and cannot be reused, but in this invention, as seen above, the high concentration liquid is applied for de-staining, so the amount of waste liquid is reduced by about 30 minutes. It can be reduced to just 1.
