Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plywood having a decorative veneer adhered to a base plate and a method for producing the same, and more particularly to a decorative plywood having high caster resistance and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, decorative plywood in which an ultra-thin decorative veneer such as cedar or hinoki is adhered to a surface of a base plate such as a plywood made of wood such as rawan wood is widely known. There are various uses for this decorative plywood, but it is also being used for applications requiring high caster resistance and the like, such as floor materials, staircase materials, and furniture top plate materials. In order to give such characteristics to decorative plywood, for example, the following method is employed. That is, the resin is injected into the decorative plywood by a decompression method or a decompression / pressure method, and the resin is polymerized by heating or the like to give the decorative plywood a plastic property.

[0003]

However, in the method of injecting a resin into decorative plywood, although the caster resistance is high, the resin must be injected by a decompression method or a pressurization / decompression method. Will also be higher. Therefore,
Such decorative plywood is expensive.

The present invention has been made in view of such circumstances, and has as its object to provide a decorative plywood having high caster resistance, being inexpensive, and easy to manufacture, and a method for manufacturing the same.

[0005]

The means for solving the problem is a decorative plywood provided with a base plate having at least a portion near the surface compacted and a decorative veneer attached to the surface.

In the decorative plywood of the present invention, at least the vicinity of the surface of the base plate to which the decorative veneer is attached is densified, so that it is hardened. For this reason, although the thin decorative plywood is stretched on the surface of the base plate, the decorative plywood is harder at least on the surface side (decorative veneer side) than the normal decorative plywood, and the caster resistance is improved. . In addition, this decorative plywood can be easily and inexpensively manufactured by, for example, passing a base plate between rollers or pressing to consolidate, and attaching a decorative veneer thereto, so that the pressure reduction method or the like can be used. It is cheaper than decorative plywood manufactured by injecting resin by pressurization / decompression.

[0007] Further, since the base plate of such a decorative plywood is consolidated by, for example, passing between rollers at a predetermined interval or pressing to a predetermined thickness, the base plate is not consolidated. In comparison, the dimensional variation of the thickness can be reduced. Therefore, the decorative plywood in which the decorative veneer is attached to the compacted base plate can also reduce the dimensional variation in the thickness. Therefore, when a plurality of decorative plywoods are used side by side, the handling can be facilitated, for example, there is no step between the decorative plywoods.

The base plate may be appropriately selected according to the use of the decorative plywood. For example, plywood made of lauan wood, conifers such as cedar and cypress, and hardwoods such as cherry and oak are available. Materials, fiberboard and the like. The base plate may be one in which at least the vicinity of the surface is compacted.For example, the base plate may be compressed by passing between heated or non-heated rollers, or the base plate may be heated or unheated. Or by being sandwiched between them.

[0009] In order to make the appearance of the decorative plywood look more beautiful, for example, in order to make the appearance of the decorative plywood more beautiful, a colorant is filled in a concave portion such as a conduit on the surface of the decorative veneer, or a paint such as a clear paint is applied to the surface of the decorative veneer. Some have layers. Further, there is a coating layer containing antifriction particles in order to improve abrasion resistance. In addition, there are some which are processed such as rape processing in order to connect and use decorative plywood.

Further, in the decorative plywood described above, it is preferable that the base plate includes a hardened resin at least in the vicinity of the surface.

[0011] In the decorative plywood of the present invention, as described above, the vicinity of the surface of the base plate is compacted and hardened. Moreover,
Since the cured resin is contained at least in the vicinity of the surface of the base plate, the vicinity of the surface is further hardened. For this reason, in the decorative plywood in which the decorative veneer is attached to such a base plate, the caster resistance is further improved. Here, the resin may be any resin that exhibits a certain degree of hardness in a hardened state and is included in at least the vicinity of the surface of the base plate. After being included, it is a resin that is cured by polymerization or the like with heat, light such as ultraviolet rays, an electron beam or gamma ray, or a solid polymer such as a polyolefin resin or a hot melt resin. Resins.

[0012] Another solution is a method for manufacturing a decorative plywood in which a decorative veneer is attached to a surface of a base plate, wherein the base plate is heated by at least one roller heated on the front surface side. A heating / compressing step of heating and compressing in the thickness direction by passing between a pair of rollers; and an attaching step of attaching the decorative veneer to the surface of the heated and compressed base plate via an adhesive. A method for producing a decorative plywood, characterized in that:

In the present invention, the base plate is heated and compressed in the heating and compressing step to consolidate at least the vicinity of its surface, and then the decorative veneer is attached to the surface in the attaching step. Since the veneer veneer is thinner than the base plate, the surface of the veneer plywood (the veneer veneer side) can be hardened similarly to the surface of the veneer plate if the vicinity of the surface of the base plate is compacted and hardened. Therefore, according to the production method of the present invention, a decorative plywood having particularly good caster resistance can be produced.

Further, in the present invention, since the heat compression is performed between the rollers at a predetermined interval, even if there is a large dimensional variation in the thickness of the base plate before the heat compression, the distance between the rollers is regulated after the heat compression. Thus, the thickness of the base plate can be reduced. Further, since the decorative veneer is thinner than the base plate, the thickness variation is small. Therefore, even after the decorative veneer is attached, a decorative plywood having a small dimensional variation in thickness can be obtained. Further, according to the production method of the present invention, it is possible to produce a decorative plywood having high caster resistance simply by heating and compressing the base plate and thereafter attaching a decorative veneer, so that a reduced pressure that requires batch processing is required. It can be manufactured easily and inexpensively as compared with decorative plywood manufactured by injecting a resin by a pressure method or a pressure / pressure reduction method.

After the sticking step, a coloring step of applying an aqueous colorant such as brown to a concave portion of a conduit or the like on the surface of the decorative plywood (surface of decorative veneer), or applying a paint such as a clear paint to the surface of the decorative plywood. The appearance can be made more beautiful by a painting process or the like. In addition, lubricating particles are mixed with the paint and applied to the surface of decorative plywood, or the lubricating particles are retained in the paint layer by applying the paint and spraying the lubricating particles from above. If this is the case, the wear resistance of the decorative plywood can also be improved.

The roller pair used for heating and compression only needs to be heated at least on the surface side of the base plate, but it is preferable to heat both rollers forming the pair. This is because heating from both sides makes it easier for the entire base plate to be compressed. The number of rollers used for heating and compression is 1
A pair may be used, but there may be a plurality of pairs. In the case of a plurality of pairs, the base plate can be compressed more reliably. Further, before or after passing through a pair of rollers to be heated and compressed, it may be passed through a pair of rollers not to be heated.

Further, the method for producing a decorative plywood according to the above, further comprising a resin application / placement step of applying or arranging a resin on the surface of the base plate before the heating and compressing step. It is good to use a manufacturing method.

In the present invention, the resin is applied or arranged on the surface of the base plate in the resin application / placement step, and then the base plate is compressed in the heat compression step. As a result, the base plate is compacted in the vicinity of its surface and is in a state containing resin. Thereafter, the resin is cured by cooling or providing a separate curing step as necessary. Once the resin cures,
The vicinity of the surface that has been hardened by consolidation by heating and compression can be further hardened. For this reason, the surface (decorative veneer side) of the decorative veneer in which the decorative veneer is adhered to the base plate can also be hardened, and therefore, the decorative veneer having higher caster resistance can be manufactured. In addition, as a method of applying or disposing the resin, if the resin is liquid, for example, a method of applying with a roll coater or a flow coater, or spraying the resin may be used.
If it is a solid such as a sheet, it may be sprayed or placed on the surface of the base plate as it is.

As a method for curing the resin contained in the vicinity of the surface of the base plate, the base plate is cured by polymerizing or the like using the heat of the rollers when the base plate is passed between the rollers, and after the heat compression step. A resin curing step may be provided separately, and the resin may be cured near the surface of the base plate by heat curing, light curing, radiation curing, or the like according to the type of the resin. Alternatively, when the base plate and the veneer veneer are heated and bonded in the attaching step, the resin contained in the vicinity of the surface of the base plate can also be cured. By doing so, it is possible to save the trouble of performing a separate curing step.

[0020] Further, the method for producing a decorative plywood according to any one of the above, further comprising, before or after the attaching step, a ridge processing step of forming a ridge on a side surface of the heated and compressed base plate. And a method for producing a decorative plywood characterized by the following.

By forming the plywood on the decorative plywood, the decorative plywood can be easily connected to each other. However, if the plywood is heated and compressed after forming the ridge on the side surface of the plywood, the portion of the plywood may be deformed. In some cases. In other words, especially when the female-shaped part is crushed and deformed by compression, it becomes impossible to fit the male-type part, or when the female-type part is compressed,
Since the pressure is not sufficiently applied, consolidation is not performed, and the portion may swell. On the other hand, in the present invention, after the base plate is heated and compressed in the heating and compressing step, burrs are formed on the side surfaces of the base plate in a burring process. For this reason, as described above, there is no problem such as crushing and deforming the portion of the seed or swelling of only the portion of the seed.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an overall view of a decorative plywood 1 of the present embodiment, and FIG. 2 shows a partially enlarged sectional view thereof. As shown in FIG. 1, the decorative plywood 1 is a decorative plywood for a floor material having a substantially rectangular and substantially plate shape. On the side surface 1C, a male type sash 18 and a female type sash 19 are formed at predetermined positions so that when a plurality of decorative plywoods 1 are used side by side, they can be connected to each other without gaps.

As shown in FIG. 2, this decorative plywood 1 has a thickness of about 11.5 mm, and is formed by laminating five layers of Lauan veneer 4 having a thickness of about 2 mm alternately vertically and horizontally. It is composed of a plywood (base plate) 2 and a cedar veneer (decorative veneer) 3 having a thickness of about 0.8 mm attached to its surface 2A (upper side in the figure). Among them, the plywood 2 is compacted in the vicinity of the front surface 2A and the back surface 2B. Furthermore, of these, surface 2
In the vicinity of A, the impregnated and cured resin 6 is contained.

The plywood 2 and the cedar veneer 3 are bonded by an adhesive layer 8 made of an adhesive. Further, a concave portion 3D such as a conduit on the surface 3A of the cedar veneer 3 is filled with a brown aqueous colorant 10 so that grain and the like can be seen beautifully. Further, an undercoat clear paint layer 12 is formed on the surface 3A of the cedar veneer 3, and an intermediate clear paint layer 14 and an overcoat clear paint layer 16 are further formed thereon. Among them, the anti-friction particles 17 are held in the intermediate clear paint layer 14.

In the decorative plywood 1, the vicinity of the surface 2A of the plywood 2 is compacted and hardened. Further, since the cured resin 6 is included in the vicinity of the surface 2A of the plywood 2, the vicinity of the surface 2A is further hardened.
The thickness of the cedar veneer 3 (about 0.8 mm) is smaller than the thickness of the plywood 2 (about 11.5 mm). For this reason, the decorative plywood 1 has extremely excellent caster resistance on the surface 1A side (upper side in the figure) as compared with a normal decorative plywood in which the surface of the base plate is not densified.

As described later, the plywood 2 of the decorative plywood 1 is heated and compressed through the rollers at predetermined intervals, so that the dimensional variation of the thickness is small. Specifically, the thickness of the plywood 2 before the heating and compression is 12 ± 0.3 mm, and there is a maximum dimensional variation of 0.6 mm, whereas the thickness of the plywood 2 after the heating and compression is 1
It is 1.5 ± 0.1 mm, and there is only a dimensional variation of up to 0.2 mm. On the other hand, cedar veneer 3 (0.8 ± 0.05 m
m) is very thin as compared with the plywood 2, so that its dimensional variation is smaller than that of the plywood 2. For this reason, there is almost no effect on the dimensional variation of the thickness of the decorative plywood 1.

Therefore, as described above, since the dimensional variation in the thickness of the plywood 2 is small, the dimensional variation in the thickness of the decorative plywood 1 is also small. When the dimensional variation of the thickness is small as described above, even when a plurality of decorative plywoods 1 are used side by side, there is almost no step between the decorative plywoods 1, so that the handling is easy. Also,
In the decorative plywood 1 of this embodiment, since the antifriction particles 17 are contained in the paint layer, specifically in the intermediate clear paint layer 14, not only the caster resistance but also the abrasion resistance are excellent. I have.

As described later, the decorative plywood 1 is manufactured using a plywood 2 which is passed between heated rolls and whose area near the surface 2A is compacted. However, the same effect can be obtained with a decorative plywood composed of a plywood 2 in which the vicinity of the surface 2A is passed between unrolled rolls and the vicinity thereof is compacted. Further, it may be a decorative plywood composed of a plywood 2 in which the vicinity of the surface 2A is compacted by a heated or non-heated press.

Next, a method of manufacturing the decorative plywood 1 will be described with reference to FIGS. First, the plywood 2 in which the lauan veneers 4 are laminated is prepared. Then, in the resin application step, as shown on the left side of FIG.
A resin paste (resin) 5 is applied to the surface 2A of the substrate ² by a roll coater 40 so as to be ² g / (30 cm) ² .

More specifically, a plywood 2 is passed between the sponge roll 41 and the feed roll 43 with the surface 2A facing the sponge roll 41, and a resin paste held between the sponge roll 41 and the applicator 42. 5 is transferred to the surface 2A of the plywood 2 and applied. In addition, this resin paste 5
Is an epoxy acrylate curable by heat and ultraviolet light. Further, since the resin paste 5 is a relatively low-molecular liquid, it easily penetrates into the vicinity of the surface 2A of the plywood 2 only by being applied.

Next, in the heating and compression step, as shown in the center of FIG. 3, the plywood 2 coated and impregnated with the resin 5 is combined with the upper compression rollers 51A, 51B and 51C and the lower compression rollers 52A, 52B and 52C. , 3 pairs (51A and 52A, 5
1B and 52B, 51C and 52C). In the present embodiment, each of the compression rollers has a diameter of 350 mm and a width of 450 mm.
It is heated to 0 ° C. and rotated at a feed speed of 50 m / min.

In the heating and compressing step, the plywood 2 is softened by the heat transmitted from the upper compression roller 51A and the like and the lower compression roller 52A and the like, and compressed between these rollers. Consolidation. Specifically, the thickness of the plywood 2 after the heating and compression becomes 11.5 ± 0.1 mm, while the thickness of the plywood 2 before the heating and compression becomes 12 ± 0.3 mm, as described above. , Dimensional variation from 0.6mm to 0.2mm
To become smaller. The thickness after heat compression is determined by the material of the plywood 2, the upper compression roller 51A and the like and the lower compression roller 52A.
Since the distance varies depending on the interval between them, the temperature, the feed speed, and the like, the conditions are changed as appropriate to obtain a desired thickness.

In the heating and compression process, the resin paste 5
Although it is slightly cured by the heat from the upper compression roller 51A and the like and the lower compression roller 52A and the like, the time required for the heat is short, and the curing is not sufficient. Therefore, the uncured resin paste 5 exists near the surface 2A of the plywood 2 that has been heated and compressed.

Then, in the resin curing step, FIG.
As shown on the right side of FIG. 5, the surface 2A of the plywood 2 is irradiated with ultraviolet rays emitted from an ultraviolet lamp 61 by a UV dryer 60 directly or via a reflector 62, and the uncured resin paste 5 is completely cured. Accordingly, the vicinity of the surface 2A of the plywood 2 has the cured resin 6, so that the vicinity of the surface 2A of the plywood 2 which has been compacted and hardened is further hardened. Further, since the cured resin 6 is integrated with the plywood 2, the portion that has been compacted by the heat compression is prevented from returning, and its thickness is securely fixed.

Next, in a burring process, a side wall 2C of the plywood 2 is shaved by a burring machine (not shown) as shown by a broken line in FIG. Form each. Next, in the sticking step, as shown in FIG. 4 (b), an adhesive 7 is applied to the surface 2A of the plywood 2 that has been heated and compressed by a spreader, and the cedar veneer 3 is stuck thereon. The whole plate 3 is bonded by heating while applying pressure.

Next, in the coloring step, using a wiping coater 80 shown in FIG. 5, a brown aqueous colorant 10 is imprinted into a concave portion 3D such as a conduit on the surface 3A of the cedar veneer 3 and colored. Make it look beautiful. That is,
Pass the surface 3A toward the sponge roll 81 side between the opposing sponge roll 81 and the feed roll 83, and apply the brown aqueous colorant 10 held between the sponge roll 81 and the applicator 82 to the cedar veneer 3 Is transferred to the surface 3A.

Thereafter, two pairs of scraping rolls 85A, 8
The unnecessary aqueous colorant 10 among the aqueous colorants 10 transferred to the surface 3A of the cedar veneer 3 is scraped through the space between the feed rolls 5A and the feed rolls 86A and 86B, and the concave portion 3D (such as a conduit) of the surface 3A. Is imprinted with an aqueous colorant 10. Thereafter, the aqueous colorant 10 is dried and cured by the heater 88 (100 ° C.
× 1 minute) to complete the coloring step. The scraped aqueous colorant 10 is collected and reused by the blades 87A and 87B.

Next, in the coating step, three clear paint layers 12, 14, 16 (FIG. 2) are formed on the surface 3A of the cedar veneer 3.
) Is formed by coating using a coating apparatus 90 shown in FIG. Specifically, first, the surface 3A is placed between the sponge roll 91A and the feed roll 93A.
The undercoat clear paint 11 (acrylic UV paint) held between the sponge roll 91A and the applicator 92A is passed through toward the side (upper side in the figure), and the surface 3 of the cedar veneer 3
A is transferred and applied to A at a coating amount of ² g / (30 cm) ² . Thereafter, the UV drier 94A causes the UV lamp 9
Undercoat clear paint 11 (surface 3A) directly or via reflector 94A2 with ultraviolet light emitted from 4A1
To cure the undercoat clear paint 11 to form an undercoat clear paint layer 12.

Next, the rubber roll 91B and the feed roll 93
B, the surface 3A is passed toward the rubber roll 91B (upward in the figure), and the rubber roll 91B and the applicator 9
The intermediate coating clear paint 13 held between 2B and 2B is transferred and applied onto the undercoat clear coating layer 12 at a coating amount of 2 / (30 cm) ² . The clear paint for intermediate coating 1
No. 3 is a 30% by weight lubricant (WA # 5) in the acrylic paint.
00, white alumina manufactured by Fujimi Incorporated)
Are mixed.

Thereafter, the intermediate clear paint 13 is irradiated with ultraviolet rays emitted from an ultraviolet lamp 94B1 directly or via a reflector 94B2 by a UV dryer 94B to cure the intermediate clear paint 13 and cure the intermediate clear paint 13. Layer 14. Further, while the plywood 2 on which the cedar veneer 3 is adhered is transported by the feed roll 93C, the clear paint 15 for top coating (acrylic U
V paint) on the intermediate clear paint layer 14 at 6 g / (3
0 cm) ² to apply.

Thereafter, the UV light from the ultraviolet lamp 94C1 is irradiated directly or via the reflector 94C2 onto the clear paint 15 for top coating by the UV dryer 94C, and the clear paint 15 for top coating is cured to form the clear paint layer 16 on the top paint. I do. In the present embodiment, since the anti-friction particles 17 are held in the intermediate clear paint layer 14, the abrasion resistance of the decorative plywood 1 is improved. In this manner, as shown in FIGS. 1 and 2, the cedar veneer 3 is attached to the surface 2A of the plywood 2 containing the consolidated and hardened resin, and three clear paint layers 12, 14, 1
The decorative plywood 1 on which 6 is formed is completed.

As described above, according to the method for manufacturing a decorative plywood of the present embodiment, the resin paste 5 is applied in the resin application step, the plywood 2 is compressed in the heating and compression step, and then the cedar is applied in the attaching step. Simply by attaching the veneer 3, high caster resistance can be obtained. In other words, this decorative plywood 1
Has high caster resistance, and compared to conventional decorative plywood manufactured by injecting resin by decompression method or pressurization / decompression method,
It can be manufactured easily and inexpensively.

In the above, the present invention has been described with reference to the embodiments. However, it is needless to say that the present invention is not limited to the above embodiments, and can be appropriately modified and applied without departing from the gist thereof. . For example, in the above embodiment, the resin 6 is impregnated and cured in the vicinity of the surface 2A of the plywood 2 by a resin application step, a resin curing step, and the like.
Even if these steps are omitted, that is, even if the resin 6 is not provided,
A decorative plywood having higher caster resistance than conventional decorative plywood can be manufactured. However, as described above, the plywood 2
It is preferable to have the cured resin 5 in the vicinity of the surface 2A because the caster resistance of the decorative plywood 1 is further increased.

In the above embodiment, the liquid resin paste 5 is applied in the resin application step and then cured in the resin curing step. However, a solid resin such as powder, granules, and sheets may be used. it can. In such a case, in the resin disposing step, the resin is placed on the surface 2A of the plywood 2 by spraying or placing the resin, and the plywood 2 is heated and compressed together with the resin in the heat compression step. At that time, the resin is melted by heat and permeates near the surface 2A of the plywood 2. Then, if the plywood 2 and the resin cool after the heating and compressing step, the resin hardens near the surface 2A of the plywood 2 and becomes hard near the surface 2A. Therefore, it is possible to proceed to a ridge processing step and the like without performing a separate resin curing step.

When a resin that is cured by radiation such as an electron beam or a gamma ray is used as the resin, the resin curing step is performed by radiation in accordance with the resin. When a thermosetting resin that can be cured at room temperature or a thermosetting resin that can be cured in a short heating time is used, the resin can be cured without performing a separate resin curing step. When a thermosetting resin is used, the resin can be cured when the cedar veneer 3 is heated and bonded to the plywood 2 in the attaching step. Also in this case, the resin curing step can be omitted.

In the heating and compression step of this embodiment, 3
Although both roller pairs are heated, at least one roller pair may be heated, and moreover, the upper compression rollers 51A, 5 compressing at least the surface 2A side of the plywood 2.
What is necessary is just to heat either 1B or 51C.
However, by heating from both sides of the plywood 2 and further heating with a plurality of roller pairs, the entire plywood 2 is more easily compressed.

Further, in the above embodiment, the burring step is performed before the bonding step. However, after the cedar veneer 3 is bonded to the plywood 2 in the bonding step, the side surfaces 2 of the plywood 2 are bonded in the burring step.
It is also possible to form a seed on C. Further, the burring step can be performed before the resin coating step (before the heating and compression step). However, in this case, in the heating and compressing step, the portion subjected to the salinity processing, in particular, the portion formed as the female type salinine 19 is crushed and deformed by compression, or
Since the pressure is not sufficiently applied, the consolidation is not performed, and there may be a problem that the thickness is increased and the portion expands. For this reason, it is preferable to perform burrs after the heat compression step. It is needless to say that in the case where the ridge processing is not particularly required, for example, when a plurality of decorative plywoods are not used side by side, the ridge processing step is omitted.

Further, in the above embodiment, the coloring step is performed so that the aqueous colorant 10
Is added to make the grain look more beautiful, but this step may be omitted as appropriate in consideration of the material of the veneer veneer to be used and the use of the veneer. In the above embodiment, the three clear paint layers 12, 14, and
Although 16 is formed, the coating layer can be made into one or two layers in consideration of the material and application conditions of the paint to be used, and the coating step is omitted from the use of decorative plywood and the like. You can also. In the present embodiment, the anti-friction particles 17 are mixed in the clear coating for intermediate coating 13 so that the anti-friction particles 17 are retained in the coating layer, but only the clear coating is applied first. Separately, the anti-friction particles 17 can be sprayed on the clear paint. It is more preferable to separately apply the anti-friction particles 17 in this way, since the decorative plywood 1 more reliably contains the predetermined amount of the anti-friction particles 17.
