DETAILED DESCRIPTION OF THE INVENTION

[0001]

The object of the present invention is to finish a veneer plate which is indispensable as a surface finishing material for various articles requiring a natural wood grain appearance, such as furniture and building materials, furniture and inner panels for vehicles. About the method,
In particular, as a finishing material for various articles, an extremely novel finishing method which is effective for performing various finishing treatments in advance at the veneer plate stage before being laminated and integrated with the article base material will be provided. It is assumed that.

2. Description of the Related Art The depletion of resources has become a problem, and it has been a considerable period of time. In the meantime, various proposals, regulations, and practical measures related to effective use of various natural resources have been made. Implementation and promotion of recycling measures have been made.
In the case of timber resources, the situation is different from that of other natural resources such as petroleum and mineral resources, and the lack of absolute numbers is not limited to the problem of securing industrial resources, but also the preservation of the global environment, Due to its significant involvement in ecological issues, measures and implementation for the effective use of its limited resources are even more critical and urgent.
It is of great interest, especially in the wood processing industry.

[0003] For this reason, high-quality timber called precious wood, whose resources are otherwise limited, is not only because it is expensive and cannot be widely spread, but also because it is most worrisome to consider depletion. As one of the countermeasures that anticipated them, at one time, so-called printed plywood, which tried to replace the wood grain of popular high-quality wood by printing processing, was sent out to the world all at once, serving as a temporary stop However, the times have changed, and in today's Japan, which has achieved great economic growth, the demands of the people have become more and more upscale, and the former printed plywood is not enough to get tired, and if it is not a real grain The extremely luxurious tide that is unsatisfactory has become commonplace, and manufacturers who can not leave it are completely aware of the depletion of resources, Hurry to establish a natural wood grain effective technical means appearance can realize a variety of development by way of industry, and has accumulated research.

One of the results is that natural wood is used as decorative veneer,
That is, the idea is to use it as a veneer. In other words, if natural wood is used as the material that constitutes the finished surface of various products at a thickness appropriate for the site, it will naturally require an enormous amount of material. Due to difficulties in product accuracy and durability due to the fact that it is made of wood, for example, because of the remaining measures against inconsistency and cracking, natural wood is thinly killed and laminated on the surface of veneer plywood and other base materials. By integrating them, it is possible to realize a decorative board that is completely the same as a natural plank in appearance, with only the surface being a natural wood layer.

In the veneer thus formed, in order to make more effective use of natural wood, the thickness of the veneer can be reduced to a small extent, and the finishing of the veneer which has become further thinner must be finished. It is necessary to address the new issue of what to do. So far, the progress of science and technology has greatly improved machines and equipment. As a practical processing technique, it is also possible to manufacture veneers sliced thinly to a thickness less than that,
At least the former problem has already been solved, not only to obtain a decorative board by laminating on a plywood with a flat surface as in the past, but also to laminate and integrate with the surface of various base materials such as fiberboard, A large number of various uses have been made, such as realizing a decorative board with a sculpture pattern by pressing with a mold with an uneven pattern, or attaching it to a bent surface with a vacuum laminator or roll press, etc. I have.

However, with respect to the latter problem, as the veneer becomes thinner, the properties of natural wood, which is an organic fibrous body, have a great influence, and the veneer plate immediately after slicing is easily torn. To solve the problem, it was necessary to reinforce the resin by impregnating it with plastics liquid or by attaching a reinforcing material such as a backing paper to the back surface and integrating it. Even if the adhesive surface is bent or uneven, even if it is integrated with the substrate surface by thermocompression bonding or other means, it is easily broken, cut or cracked along the grain, regardless of the fiber direction In addition to the harmful effects such as the occurrence of defects, even if they are simply laminated and integrated on a flat surface, even the slight unevenness of the underlying surface is directly In the uniform mechanical polishing process, there is a problem that even the veneer is partially scraped, exposing the base, and the inconvenience of inefficient manual surface finishing is also required. In addition, if various chemicals and paints are applied and impregnated for various purposes, for example, insect repellent, antiseptic, flameproofing measures, surface protection and cosmetic measures, etc., these chemicals and paints are easily veneered. Because much penetrates and adsorbs to the substrate side through the base plate, is the intended purpose not achieved?
In order to achieve it, we have to consume a lot of chemicals and paints,
There still remain problems such as the necessity of extremely uneconomical processing, and so far, no effective proposal has been made so far to address these various difficult problems.

Therefore, up to now, 0.1 m
Since the use of ultra-thin veneers of around m involves considerable danger, veneers with a greater thickness are often used as decorative veneers, and have been proposed and implemented so far. The technology is limited to those that are solely for reinforcing mechanical strength, rather than the solutions that must be considered because of the above-mentioned ultra-thin ones.
For example, 1984 Patent Application Publication No. 49189, "the veneer veneer manufacturing process" as in the present invention, the basis weight 25 to 50 g / m ² of the backing material was prepared by thermocompression bonding spunbonded method for reinforcement A nonwoven fabric is used as a reinforcing material, and it is placed on an adhesive applied on a base plate (substrate), and a veneer plate is stacked as an interposed state. By performing thermocompression bonding, the veneer backing method using two coatings and two thermocompression bonding methods up to that time has been changed to 1
As proposed by the technology of improving the process to a single application one-time thermocompression bonding method and the invention of Patent Application Publication No. 2058, “Method of Manufacturing Laminated Veneer Single Sheet Sheet” in 1988, Substrate part in the invention of the `` plate manufacturing method '',
A non-adhesive member, that is, a release paper coated with a silicone resin or the like, a plate made of a fluororesin, polyethylene, or the like is replaced with a resin solution, Japanese paper, a fibrous sheet such as a nonwoven fabric, a veneer plate, and the like. Technical proposals such as the technique of obtaining a laminated decorative veneer sheet by compressing and integrating the board, backing it with a fibrous sheet, and peeling off the reinforced veneer part from the non-adhesive member to obtain a laminated decorative veneer sheet Is found in many.

In the present invention, in view of the above situation,
Ultra-thin veneer, for example, those currently in practical use, about 0.2 mm, or even less, even before being laminated and integrated with the target substrate as a veneer In the veneer base plate stage, various finishing processes required for the surface decorative plate of the target base material are preliminarily applied, and as before, various finishing processes are performed after being laminated and integrated with the base material. Various adverse effects resulting from the application, for example, in the final surface polishing process, because it is disturbed by the slight unevenness of the base surface due to the ultra-thin veneer plate, mechanical polishing can not be performed The disadvantage of having to resort to manual polishing finish, and if you try to finish the mechanical polishing process at the backed veneer stage,
If you try to apply or impregnate various chemicals and paints for the purpose of preventing harmful effects such as wrinkling or tearing due to too thin, insect repellent, antiseptic, flameproofing, surface protection and cosmetic measures, these chemicals, Since the paint easily penetrates the veneer and easily penetrates and is adsorbed to the base material side, it has had to consume a large amount of chemicals and paint in order to achieve the intended purpose, Alternatively, when the color matching at the time of the finish coating process is not the same surface where the treated surface is continuous in a flat shape, or when a plurality of objects are used as a set, such as a braid, etc. The harmful effects such as the need for meticulous and advanced technology to prevent the occurrence of color unevenness are wiped out universally, and even ultra-thin veneers can be adopted for surface decorative boards without any problem. Summary of the configuration as shown We developed a method of finish novel veneer element plate which are those which make it possible to complete, for practical use.

[0009]

The method for finishing a veneer blank according to the present invention is as follows.
This is a finishing method basically realized by the following configuration. That is, while having a very smooth and adhesive temporary adhesion surface structure, at least on a temporary adhesion substrate having at least a rigidity that is advantageous in terms of portable handling, a desired veneer plate is
Adhesive is applied and / or bonded and / or impregnated with an interposed reinforcing sheet interposed therebetween, and the pressure-sensitive adhesive sheet is integrated, temporarily attached substrate, single-sided temporarily attached adhesive layer, reinforcing sheet, adhesive layer, veneer element By forming the plate into a laminated structure, a veneer plate lined with a reinforcing sheet is formed into a temporary reinforcing substrate and a temporary reinforcing substrate to form a portable reinforcing veneer plate. As it is, it passes through a polishing machine such as a wide belt sander, even if it is an extremely thin veneer plate, wrinkles and cracks,
This is a method for finishing a veneer plate that allows the entire surface to be subjected to mechanical polishing without causing peeling or the like.

The present invention also relates to a method for finishing a veneer plate having the following structure, which relates to the method for finishing a veneer plate forming the basis of the present invention described above.
It has an extremely smooth and adhesive temporary adhesive surface structure, and at least on a temporary adhesive substrate having at least a rigidity that is advantageous in terms of portable handling, a desired veneer plate is coated with an adhesive as appropriate. // Compression bonding and integration with the interposed reinforcing sheet as the impregnating upper layer, into a laminated structure consisting of a temporary bonding substrate, a single-sided temporary bonding adhesive layer, a reinforcing sheet, an adhesive layer, and a veneer blank. By forming, the veneer base plate lined with the reinforcing sheet is made into a portable reinforcing veneer base plate which is integrated with the temporary mounting substrate in a temporary mounting state, and the portable reinforcing veneer base plate remains as it is. After passing through a polishing machine such as a wide belt sander, the entire surface of the ultra-thin veneer plate is smoothed by mechanical polishing without causing wrinkles, cracks, peeling, etc. Polish the smoothed veneer plate for each mounting substrate. Removed from the machine and transferred to the chemical processing machine, apply and impregnate various chemical solutions according to the purpose in the optimal amount, and ensure that these various chemical solutions are fixed in the veneer plate in the drying process without excess or shortage. This is a method of finishing a veneer blank having the following features.

Further, the above-described method for finishing a veneer plate forming the basis of the present invention also includes a method for finishing a veneer plate having the following structure. That is, while having a very smooth and adhesive temporary adhesion surface structure, at least on a temporary adhesion substrate having at least a rigidity that is advantageous in terms of portable handling, a desired veneer plate is coated with an adhesive as appropriate. // Compression bonding and integration with the interposed reinforcing sheet as the impregnating upper layer, into a laminated structure consisting of a temporary bonding substrate, a single-sided temporary bonding adhesive layer, a reinforcing sheet, an adhesive layer, and a veneer blank. By forming, the veneer base plate lined with the reinforcing sheet is made into a portable reinforcing veneer base plate which is integrated with the temporary mounting substrate in a temporary mounting state, and the portable reinforcing veneer base plate remains as it is. After passing through a polishing machine such as a wide belt sander, the entire surface of the ultra-thin veneer plate is smoothed by mechanical polishing without causing wrinkles, cracks, peeling, etc. Polish the smooth veneer plate for each substrate Removed from transferred to drug treatment machine,
Apply and impregnate various chemical solutions according to the purpose in optimal amounts,
In the drying step, these various chemicals are fixed in the veneer plate without excess and shortage, and further, the veneer plate is moved to the coating step for each temporary adhesion substrate so that a uniform coating film forming process is performed. This is a method for finishing a veneer plate.

[0012] The temporary attachment substrate reinforces a veneer plate (a natural ultrathin plate that has been cut off from a log to a predetermined thickness, has not been subjected to any processing, and has not been reinforced). When backing with a sheet, it serves as a base plate for placing and supporting them, and as a shielding plate to prevent the dissipation of adhesive, and a reinforcing sheet is lined with the back of the veneer base plate, integrated Even after being made, it is handled as it is in a state of being temporarily attached to the back of the reinforcing sheet, that is, laminated and integrated with an adhesive structure that can be easily peeled off from the back of the reinforcing sheet as needed, It must be able to function safely to prevent the handling of the veneer plate from becoming unwieldy with only the reinforcing sheet, to support the veneer plate itself when performing various processing, and to prevent the diffusion of various chemicals. Ba Razz, and therefore, the surface is,
It has a surface structure that is as smooth as possible, and has a surface structure that only temporarily adheres to various adhesives. Not yet, furthermore, it is relatively safe to carry as a whole, and other handling can be performed as a whole by being laminated and integrated with the backed veneer plate, although it is temporarily attached, For example, it is made of a metal plate such as an aluminum alloy having a fluorine resin thin film layer firmly formed on the surface, a fluorine resin plate, a polyethylene plate, or the like.

The reinforcing sheet is laminated on the back surface of the veneer plate,
After being integrated and functioning as a backing material, even after being separated from the temporary attachment substrate,
It must be able to perform the function of continuously reinforcing the veneer plate to the end by adhering and interposing it to the surface of the target article's underlying structure, and the base material itself is reflected on the veneer plate side It must have a surface property that does not cause it to be impregnated and be able to appropriately penetrate and impregnate adhesives and various chemicals.For example, in addition to thin paper such as Japanese paper or rice paper, continuous long fibers It is possible to adopt a thin non-woven fabric or the like formed mainly of.

The lamination and integration of the reinforcing sheet and the veneer plate on the temporary mounting substrate are performed by applying an adhesive onto the temporary mounting substrate, placing the reinforcing sheet on the temporary mounting substrate, and performing thermocompression once. After bonding both in a temporary adhesion form, applying an adhesive again to the reinforcing sheet surface, stacking the veneer plate, and again thermocompression bonding to laminate and integrate the three members, so-called twice A means based on a two-time application thermocompression bonding method may be employed, or after a reinforcing sheet impregnated with a resin solution is placed on the surface of the temporary bonding base material, the adhesive plate is brought into a wet state when the adhesive is wet. The plates are stacked and thermocompressed, and the three members are laminated and integrated, or the reinforcing sheet is first placed on the surface of the temporary attachment substrate,
After that, an adhesive is applied from the surface of the reinforcing sheet and the veneer plate is laminated and thermocompressed in a state of being impregnated,
Conversely, in a state where the adhesive is first sufficiently applied on the temporary bonding substrate, sequentially, in order of the reinforcing sheet, the veneer plate,
In the process of thermocompression bonding, a means for laminating and integrating the three members so that the adhesive on the temporary bonding substrate is allowed to exude from the reinforcing sheet to reach the back surface of the veneer plate, ie, one application and one application There is no problem even if a thermocompression bonding method is used, and it is sufficient if an optimal means is appropriately adopted according to the situation.

The polishing machine employed in the mechanical polishing process is not particularly limited to various types of polishing machines that are already widely used as long as they can perform fine surface finishing. , For example, a double bar sander NS
F.40 (trade name, manufactured by Takekawa Iron Works Co., Ltd.) and the like can also perform the same surface finishing process as a normal wood board, and wrinkles, cracks, peeling phenomena, etc. may occur on any veneer plate. Will not cause.

The adhesives, various chemicals, and paints may also be used according to the desired function, physical properties, purpose and purpose. Either of them can be freely selected, and they may or may not contain an organic solvent. For example, in the case of adhesives, most commonly used vinyl acetate-vinyl chloride copolymers and ethoxylates are used. Outside the resin,
Polyurethane, diallyl phthalate resin, acrylic resin and other various thermoplastic resins and thermosetting resins (however, thermosetting resins are more advantageous in terms of fluidity, creep properties, heat return properties, etc.) alone or Alternatively, two or more types may be appropriately used in a conventional manner, or a backing plate having moderate flexibility may be formed instead of natural rubber or synthetic rubber. There is no problem. In order to more clearly understand the configuration as the gist of the method for processing the veneer plate of the present invention based on the configuration as described above, the most typical embodiments will be specifically described below. I will see it.

[0017]

Example 1 An adhesive 3 of a thermally crosslinked modified SBR resin (manufactured by Mitsui Toatsu, Structbond SB-1124) was applied on a temporary adhesion substrate 4 made of a Teflon-processed aluminum alloy plate by a spreader, and then applied to a nonwoven fabric. (15g polyester /
m ² ) 2 and a 0.15 mm-thick Kusunoki veneer plate were successively stacked and hot-pressed at 100 ° C. for 1 minute at 7 kg / cm ² ,
The nonwoven fabric 2 and the natural thin wood veneer 1 are integrated on the Teflon-processed aluminum alloy plate 4 to form a portable reinforced veneer 5 having a layer structure as shown in an enlarged sectional view of a main part of FIG. . As the adhesive 3, a thermally crosslinked type modified SBR resin (Structbond SB-1124.C-1 by Mitsui Toshio) was used, and the coating amount was 100 g / m ² on a dry basis.

The portable reinforcing veneer 5 thus obtained is
As schematically shown in FIG. 1, the wide belt sander 6 (manufactured by Takekawa Iron Works, NSX-130)
F), the surface of the natural thin wood veneer 1 is polished and finished to a desired state, so that the surface has been polished in advance before being used as a surface finishing material of a target product. Natural wood thin veneer 1 can be obtained. As a result of examining the polishing state of the thin natural wood veneer 1 processed by this finishing method, the natural thin wood veneer 1 was completely peeled off, wrinkled,
No phenomenon such as cracks occurred, and a smooth and uniform finish could be confirmed.

[0019]

[Embodiment 2] Next, the portable reinforcing veneer 5, which has been subjected to the polishing and finishing process on the surface of the natural thin wooden veneer 1 in the above-mentioned embodiment 1, is moved onto a work table as it is, and the spray gun 7
After bleaching agent 8 (Nitto Kagaku Kenkyusho, Select Bleach) is applied and impregnated in the drying room at 60 ° C. for 3 hours.
After curing for 0 minutes, it is removed and bleached. As a result of examining the surface state, the natural brown thin veneer 1 was unified with the original brownish brown color tone and shade difference, and was unified to a nearly uniform white color tone. In Example 1, as in Example 1, no deformation phenomenon such as peeling or wrinkling was observed.

[0020]

EXAMPLE 3 Subsequently, as shown in the perspective view of FIG. 2, a spray gun 7 was used to spray a colorant 8 '(manufactured by Hamani Paint, mighty color S dark color, red 50g, yellow 10g).
g, black 40 g, and thinner 900 g), and after curing, subjected to a coloring process for coloring in a desired color by accelerating the curing in a drying room at 50 ° C. for 30 minutes, and then subjected to a Teflon process. By peeling the nonwoven fabric 2 and the natural thin wood veneer 1 from the aluminum alloy plate 4 from the portion of the nonwoven fabric 2, a decorative veneer laminate sheet colored and painted, the back surface of which is reinforced with the nonwoven fabric 2, is obtained. No defects could be found in the decorative veneer laminated sheet thus processed.

The laminated veneer laminated sheet having the colored surface finish is, for example, a curved surface bonded vacuum press 9 (manufactured by Save, WWA-280-4 × 10) as shown in FIG.
By laminating as the surface finishing material of the vehicle door panel 10 in -T) and performing the curved surface bonding, it is possible to obtain the vehicle door panel 10 as shown in FIG. The vehicle door panel 10 is realized as having no appearance of cracks, cracks, and the like, and having an appearance recognizable as a component made of a natural wooden board having an extremely good surface finish.

[0022]

As described above, the method for processing a veneer plate according to the present invention is completed at the veneer plate stage before the veneer is bonded to and integrated with various target parts and parts. Laminate reinforced sheet for backing veneer plate to enable chemical solution treatment and film formation treatment with functions and physical properties according to various purposes and applications, from sophisticated surface finishing treatment required for products In the integration stage, when a temporary attachment substrate having a regulated property to be adopted as its base plate is temporarily attached to the back surface of the reinforcing sheet even after the completion of the reinforcing sheet bonding step, and is transferred to each processing apparatus. As well as ensuring the safety of the veneer base plate, in each processing step, the veneer base plate itself serves as a supporting medium so that a wrinkle phenomenon, a cracking phenomenon, a peeling phenomenon, etc. do not occur on the veneer base plate. Outside, various purposes and applications It also functions as a shielding plate that reliably prevents the dissipation of chemicals and wasteful use.Moreover, a coating film of the desired color and thickness that has been examined at once is applied to the entire surface of a single wide veneer plate. It is also possible to form them, even if they are cut and adhered to each part of the target product separately, even if they are used, they do not generate color unevenness at all, and temporarily make them as finished products, for some reason Even if re-painting is required, the penetration of the paint is small and economical.

Therefore, according to the method for processing a veneer blank according to the present invention, the conventional woodworking operation using a veneer as a decorative board can greatly simplify the work process, and a large number of high-quality woodwork products can be produced. In addition to making it possible to manufacture it as an elaborate product, it is also possible to greatly reduce the amount of various chemicals and paints consumed in the process, greatly contributing to a reduction in manufacturing costs as a whole. It has the excellent feature of being able to do it.

In addition, the method for processing a veneer blank according to the present invention has a thickness of 0.1 m, which has been considered difficult to employ.
m can be used freely as a natural wood-finished board for various products. Naturally, the number of veneer boards that can be processed from a single log is dramatically increased. It is possible to drastically reduce the consumption of precious and high-quality timber, whose quantity is extremely limited.The depletion phenomenon is remarkable, and even more severe restrictions will be imposed in the future. It will be an invention that can greatly contribute to the brazing wood processing industry, and is expected to be highly evaluated in various fields as an excellent technology that minimizes the consumption of precious natural resources.
