この発明は人工化粧単板の製造方法に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.
人工化粧単板の木目模様に、天然木に特有の多色感2色
彩の濃淡変化などの自然感を付与するのに、従来より積
層接着する素材単板の1枚ごとに異なる染色を施すなど
の方法が採られているが、各素材単板については染色は

して得られる人工化粧単板に表現される木目模様には、
前述の天然木に特有の色彩の濃淡変化を十分に再現する
ことができず、天然木の木質感を忠実に再現することが
できなかった。In order to give the wood grain pattern of artificial decorative veneers a natural feel, such as the multicolored shading of two colors that is unique to natural wood, we have traditionally applied different dyes to each veneer of the material that is laminated and glued together. However, since the dyeing is done uniformly for each material veneer, the wood grain pattern expressed on the artificially decorated veneer obtained by slicing the flitched veneer is
It was not possible to sufficiently reproduce the above-mentioned changes in color shading peculiar to natural wood, and it was not possible to faithfully reproduce the wood texture of natural wood.

を付与する方法が可能である。As an example of a method for producing an artificially decorated veneer that eliminates the drawbacks of the conventional method, in a decoloring process performed as a pre-process of the dyeing process, the surface of the material veneer 10 is removed as shown in FIGS. 1 and 2. A caul plate 2 made of polyethylene, holiflopyrene, stainless steel, etc. is partially superimposed on the caulking plate 20, and this is immersed in a decoloring agent such as a hydrogen peroxide aqueous solution and a sodium hypochlorite aqueous solution to perform a decoloring treatment. causing uneven decolorization between the overlapping part and other parts, and causing color unevenness as shown in FIGS. 3 and 4 due to the dyeing unevenness in the subsequent dyeing process,
A method of imparting color shading to the wood grain pattern of the artificial decorative veneer 3 as shown in FIGS. 5 and 6 by layering, flitching, and slicing the dyed veneers obtained in this way. is possible.
さらに、天然木のもつ木質感を出すために、例えば前記

考えられる。Furthermore, in order to bring out the wood texture of natural wood, for example, in the dyeing process in the above-mentioned manufacturing method, we use a fresh dyeing bath that has been mixed with dye and a so-called dye bath that has already been dyed many times and is on the verge of being discarded. Two types of long-run dyeing baths are used, and the raw material veneer is dyed twice by these dyeing baths.
It is also possible to divide all types of veneers into different colors, combine these dyed veneers, make flitches, and slice them to obtain artificially decorated veneers.
このような2種類の染色浴で染色処理することにより、
前記ロングラン染色浴による染色単板の明度の低いくす
みのある材色と、新鮮な染色浴による染色単板の明度の
高い鮮やかな材色の組み合わせに基づき天然木に酷似し
た深みのある濃淡変化を再現することができる。By dyeing with these two types of dye baths,
The combination of the low brightness and dull color of the veneer dyed with the long-run dye bath and the bright and bright color of the veneer dyed with the fresh dye bath creates a deep shade change that closely resembles natural wood. Can be reproduced.
しかしながら、前記の方法においては、脱色工程におけ

に欠けるという欠点を有する。However, in the above method, the patch plate 20 in the decolorization process must be removed after the polymerization process and the decolorization process and before proceeding to the dyeing process, which is not only troublesome, but also requires It has the disadvantage that the change in shade between the part where 2 is polymerized and the part where it is not is too conspicuous and lacks a natural feel.
また、前述の2種類の染色浴を用いる染色処理方法にお
いては、単板を2種類に染色弁けしなげればならず、作
業が面倒であるという欠点を有する。In addition, the above-mentioned dyeing method using two types of dyeing baths has the disadvantage that the veneer must be divided into two types of dyeing baths, making the work cumbersome.
したがって、この発明の目的は、処理工程が簡単でかつ
ヤニ感2色彩の濃淡むら、多色感など天然木のもつ木質

法を提供することである。Therefore, it is an object of the present invention to provide a method for manufacturing artificial decorative veneer that has a simple processing process and can faithfully reproduce the wood texture of natural wood, such as unevenness of light and shade with two colors of resin and multicolor feeling. That's true.
この発明の一実施例を第7図ないし第9図に基づき以下
に説明する。An embodiment of the present invention will be described below with reference to FIGS. 7 to 9.
すなわち、この人工化粧単板の製造方法は、第7図およ

材単板10間に介在させて積層し、この積層状態のまま
第9図に示すようにかご詰6などして染色液中に浸漬し
、染色液を前記めくら板5に直交する方向(矢符骨P)
に流して素材単板1の染色を行なう。That is, as shown in FIGS. 7 and 8, this artificially decorated veneer manufacturing method uses metal on both one surface of the spacer 4, such as a wire mesh, that does not impede the permeation of the liquid flow, or the opposite surface thereof. Blind boards 5 formed of boards are pasted at desired intervals, and as shown in FIG. 8, these are laminated with intervening material veneers 10 to be dyed, and in this laminated state, as shown in FIG. 9. As shown in FIG.
The material veneer 1 is dyed.
このようにして得たむら染め単板を積層・接着・圧締処
理してフリッチ化し、得られたフリッチを所望の方向に
スライスして人工化粧単板とする。The unevenly dyed veneer thus obtained is laminated, bonded, and pressed to form a flitch, and the resulting flitch is sliced in a desired direction to produce an artificial decorative veneer.
このようにしたため、前記染色処理工程において、スペ

単板に天然木に近似した多色感を与えることができる。Therefore, in the dyeing process, the dyeing liquid flows through the gaps created between the laminated material veneers by the spacer 4, and the blind plate 50 is formed on the surface of the material veneer 1.
Not only does uneven dyeing occur between the abutting part and other parts, but also a streamlined pattern of dark and light stripes caused by the liquid flow and a vortex of the dyeing liquid that occurs in the area where the blind plate 5 is pasted cause the material to become uneven. In the case of an artificially decorated veneer that reproduces a straight-grained pattern, such as a darkly dyed area appearing near the contact area of the blind board 5 of the board 1, these linear patterns and color irregularities will give a tarnished feel, and the board will In the case of an artificial decorative veneer that reproduces the eye pattern, it is possible to express color unevenness and give the artificial decorative veneer a multicolored feel that resembles natural wood.
なお、前記染色処理工程において、めくら板当接部にお

るなどの方法が可能である。In addition, in the dyeing process, if you want to emphasize the undyed effect at the contact area of the blind plate, as shown in FIG. A method such as pressing the portion corresponding to the pasting part 5 with a presser bar 7 is possible.

をロール10で転送し連続的に処理して、バッチ方式に
よる場合の煩雑な作業を大幅に省略することもできる。In addition, before the dyeing process of the material veneer 1, it is generally decolorized and washed with hot water, and after the dyeing process, a drying process is performed. In some cases, a series of these steps is performed to produce a rotary sliced veneer 9 cut from log 8 as shown in FIG.
It is also possible to transfer the raw materials using rolls 10 and process them continuously, thereby greatly omitting the complicated work that would be required in the case of a batch method.

ばよい。In the case of this continuous processing method, the spacer 4 that imparts uneven dyeing to the material veneer is formed into a band shape, and the spacer 4 is wound up and set before the decolorization process B, and is cut out from the raw wood 8. The spacer 4 is fed out at a speed synchronized with the feeding speed of the rotary sliced veneer 9, which is superimposed on the rotary sliced veneer 9, and sequentially carried out by each roll 10, followed by a decolorizing process B, a hot water washing process C2, a dyeing process, and drying. What is necessary is to wind it up after transferring it to processing step E.

。In addition, in the continuous processing method, the dyeing bath can be managed by correcting the dyeing bath as necessary by sampling the dye appropriately during the continuous processing, and if the veneer has a light tone, it may be necessary to perform dyeing bath management during the hot water washing process. Extraction processing may be performed in .
また染色処理時間の調節は、ロータリスライス単板9を

ができるという効果を有する。As described above, the method for manufacturing artificially decorated veneer of this invention is as follows:
Laminate the material veneers through a liquid-permeable spacer with a blind plate pasted on a part, dye it by flowing a dye solution from the direction intersecting the blind plate of the spacer, and then bond the dyed veneers in layers.・Since the flitch obtained by pressing is sliced, there is no need for troublesome work such as joining and removing patch plates, and there is no need to prepare multiple types of dyeing baths, making it extremely simple. Through this process, the wood grain pattern of the artificially decorated veneer obtained has two-color shading and unevenness.
It has the effect of faithfully reproducing the wood texture unique to natural wood, such as multicolored appearance.
