DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative member by lapping, which imparts a high designability to a decorative decorative member used for interior decoration, flooring, furniture and the like, and a method for producing the same.

[0002]

2. Description of the Related Art Conventional printing decorative members generally have a structure shown in FIG.
The direct printing decorative board (20) shown in (1) was used. In this method, the plywood of the wood base material (21) is filled with an acrylic vinyl acetate emulsion containing an extender, and then the wood pattern is directly printed on the surface of the wood base material by a gravure offset method (23). A protective layer (22) was formed by applying a polyurethane paint or the like with a roll coater or a flow coater for protection and appearance improvement. As another method similar to the present invention, there is a wrapping decorative member (30) shown in FIG. This is done by printing a wood grain pattern or solid printing on a polyvinyl chloride sheet (32) with pearl or metallic ink (33), matching the printing surface to the surface of the plywood, and using a transparent adhesive (34). It was wrapped.

[0003]

However, the above-described method of direct printing on plywood is a gravure offset method, in which the pattern of the plate cylinder is once transferred to a rubber blanket, and the transferred pattern is again printed on plywood. How to print. For this reason, the transfer amount of ink is limited, and there is a problem that the printed grain pattern feels unsatisfactory in its reproducibility and design feeling as compared with the grain of natural wood.
In addition, although a polyurethane-based paint or the like is used as a protective layer on the printing surface, sufficient physical strength was not obtained because the layer was thin. On the other hand, the decorative member wrapped with the printed polyvinyl chloride sheet has strong physical properties as compared with the above-described direct-print decorative plate because the surface thereof has a polyvinyl chloride sheet layer formed thereon. Because the handle has not penetrated into the fiber layer of the wooden base,
It lacked the brightness and depth of natural wood. The present invention has been made in view of the above problems, and has as its object to provide a decorative member having high designability and a method for manufacturing the same.

[0004]

In order to achieve the above object, as shown in FIG. 1, a decorative member according to the present invention comprises a plastic sheet layer (12) which is more transparent or translucent than an upper layer, and a wood-grained printed layer. (13), a transparent adhesive layer (14), a print layer (15) made of pearl or metallic ink, and a wood substrate (11).
On the surface of a wood substrate on which a wood grain pattern or solid printing is directly printed using pearl or metallic tone ink, align the printed surface of a transparent or translucent plastic sheet with a wood grain pattern printed using a normal printing ink. It is characterized by lapping.

In the above, a sheet made of polyvinyl chloride, acrylic resin, fluororesin, polyethylene, polypropylene, polyethylene terephthalate or the like is used as the transparent or translucent plastic sheet of the present invention.

The woody base material of the present invention includes plywood,
Particle board, medium density fiber board, etc. are used.

[0007] In addition, the wrapping process
A plastic sheet and a wooden substrate are bonded together using a transparent adhesive.

Further, the woodgrain pattern printed on the woody base material of the present invention and the woodgrain pattern printed on the plastic sheet are not the same, but only form a single woodgrain pattern together.

[0009] Ordinary printing inks are printing inks generally used for printing building materials, and do not have special characteristics in color tone or hue such as pearl or metallic tone. It is.

[0010]

[Function] A wood grain pattern printed on a wood base material with a pearl or metallic tone ink penetrates to some extent into the fiber structure of the wood base material, so that a sense of brightness and depth are expressed by irregular reflection of light. In addition to the wood pattern printed on the plastic sheet, this synergistic effect produces high designability. Further, since the plastic sheet is formed on the surface of the decorative member, it is possible to provide excellent surface physical properties that cannot be expected with conventional direct printing plywood.

[0011]

[Example] On four sides of a plywood formed by laminating veneer veneers into a bar shape, solid printing of metallic-colored ink was performed, wiping was performed, and the conduit was filled with ink. Printed. In a separate step, a woodgrain pattern constituting one woodgrain pattern together with the woodgrain pattern printed on the plywood was printed on a 0.1 mm polyvinyl chloride sheet by a gravure offset method. Next, the printed surface of the polyvinyl chloride sheet is aligned with the printed surface of the plywood, and the polyvinyl chloride sheet is wrapped on the four surfaces of the plywood using a transparent polyurethane adhesive. A member was manufactured. In addition, the lapping process is a vacuum forming method by heating a sheet and applying a transparent alkyd resin, epoxy resin, polyurethane resin thermosetting resin adhesive or vinyl acetate hot melt adhesive on the back surface. Alternatively, lapping is performed by a pressure roll method.

Although the member manufactured by the manufacturing method of the present invention uses inexpensive lauan plywood as a base material, it looks like a grain of expensive precious wood from the appearance, and has a sense of brightness and depth. It was a decorative member having high design properties.

[0013]

According to the production method of the present invention, a synergistic effect between a woodgrain pattern printed with a pearl or metallic-tone ink that has penetrated to some extent into the fiber structure of a wood substrate and a woodgrain pattern printed on a plastic sheet As a result, a decorative member having high designability having a sense of brightness and depth that cannot be obtained with a conventional printing decorative member can be obtained.

The wrapping decorative member of the present invention has a plastic sheet formed on its surface.
It has excellent surface properties such as weather resistance, abrasion resistance, and stain resistance that are not available in conventional decorative members.

Further, according to the manufacturing method of the present invention, high designability having luminance, illuminance, depth and the like similar to the grain of expensive precious wood using inexpensive plywood, particle board, medium density fiberboard and the like. A decorative member is obtained.
