JPH0342077A - Production of wood grained decorative sheet - Google Patents

Abstract

PURPOSE:To facilitate the production of a decorative sheet having a wood grain pattern by forming recessed and projection part having a wood grain pattern on the surface of wood and successively coating the surface with lacquer and urethane resin. CONSTITUTION:Recessed and projection part 3 having a wood grain pattern are formed on the surface of wood 1 and the surface is coated with lacquer 7 to relieve the wood grain pattern against the wood 1 by the lacquer thickened at the recessed and projection part 3. A protective film 9 of urethan resin, etc., is further formed on the surface of the lacquer layer 7. Conventional labor required to adhere a vinyl sheet, etc., is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for producing decorative wood-grained laminates.

Conventional Techniques Conventional methods for manufacturing wood-grained decorative boards include gluing so-called sutras, which are thinly shaved pieces of real wood with regular grains, onto the surface of wood such as plywood; Methods such as gluing printed vinyl sheets etc. have been adopted.

Problems to be Solved by the Invention However, the above-mentioned conventional method for producing a wood-grained decorative board has the following problems.

(1) The work of gluing scriptures, vinyl sheets, etc. onto the wooden surface is complicated, and wrinkles are likely to occur especially when gluing vinyl sheets.

(2) When the surface of the bare wood is uneven, it becomes even more difficult for vinyl sheets etc. to adhere to it.

The present invention makes it possible to solve the above-mentioned conventional problems by printing a wood grain pattern on the surface of a bare wood to produce a decorative board with wood grain.

Means for solving the problem (1) Forming concave and convex portions in a wood grain pattern on the surface of the bare wood, and applying lacquer to the surface of the bare wood on which the concave and convex portions have been formed to form a lacquer coating layer. A protective film layer made of urethane resin or the like was then formed on the surface of the lacquer coating layer to produce a decorative board with wood grain.

(2) Polish the surface of the bare wood, apply lacquer to the surface to form a lacquer coating layer, print a wood grain pattern on the surface of the lacquer coating layer, and print a lacquer coating layer with the wood grain pattern printed on it. A protective film layer made of urethane resin or the like was formed on the surface to produce a decorative board with wood grain.

In the manufacturing method described in item 1, concavities and convexities with a wood grain pattern are formed on the surface of the bare wood, so when lacquer is applied to the surface, the lacquer penetrates into the concavities and convexities, and becomes darker in the concave areas. The convex portions are coated thinly, and the wood grain pattern formed by the concave and convex portions stands out on the surface of the wood, and is protected by a protective film layer such as urethane resin.

In addition, in the manufacturing method of item 2, since the wood grain pattern is printed on the surface of the lacquer coating layer applied and formed on the surface of the bare wood, the desired wood grain pattern can be displayed, and the wood grain pattern can be displayed. The printed surface of the pattern is protected by a protective film layer such as urethane resin.

EXAMPLES Next, the present invention will be explained with reference to the drawings. 1 to 3 show the manufacturing method described in item 1.

FIG. 1 is an explanatory diagram showing the first step, in which the surface of the bare wood l is polished, and the surface has concave and convex portions 2.3 with a wood grain pattern.
form. 4 is a concave wood grain pattern.

This is a rotor for forming the convex portion 2.3, and the rotor 4
A corrugated (N13...5) is formed on the surface of
These teeth 5...5 form concave grooves in a regular pattern on the surface of the bare wood l.

FIG. 2 is an explanatory diagram showing the second step, in which lacquer is applied to the surface of the wood base 1 on which the concave and convex portions 2 and 3 forming the wood grain pattern are formed using a rubber roller 6 for lacquer coating, and the applied lacquer is The surface is polished with a polishing machine (not shown), and after polishing, lacquer is further applied and polished again, and the coating and polishing process is repeated several times to form a lacquer coating layer 7 on the surface of the wood l.

FIG. 3 is an explanatory diagram showing the third step, in which a urethane resin is applied to the surface of the lacquer coating layer 7 using a rubber roller 8 for forming a protective film layer, and the resin is coated several times to protect the surface of the lacquer coating layer 7. A membrane layer 9 is formed.

In this way, the lacquer coating layer 7 and the protective film layer 9 are laminated on the surface of the wood l as shown in FIG. Decorative boards will be manufactured.

In addition, there are large marks on the surface of the bare wood as shown in Figure 5.

Rotating cutter 10 with stepped surfaces of different small diameters,
After forming step surfaces 12 and 13 in step 11, the steps 1 to 1 described above are performed.
By performing the third step, a wood grain pattern can also be formed on the surface of the bare wood l having the stepped surfaces 12 and 13.

If a desired wood grain pattern is applied as described above, a decorative board 14 as shown in FIG. 6 can be manufactured. 7 to 9 show the manufacturing method described in item 2.

FIG. 7 is an explanatory diagram showing the first step, in which lacquer is applied to the surface of the polished wood l with a rubber roller 15 for lacquer coating, and the surface of the applied lacquer is polished with a polishing machine (not shown). Then, lacquer is applied and polished again, and the coating and polishing are repeated several times to form a lacquer coating layer 16 on the surface of the wood l.

FIG. 8 is an explanatory view showing the second step, in which a wood grain pattern is printed on the surface of the lacquer coating layer 16 using a rubber roller 17 for wood grain pattern printing to form a wood grain pattern printing layer 18.

FIG. 9 is an explanatory diagram showing the third step, in which urethane resin is coated several times on the surface of the wood grain pattern printed layer 18 using a rubber roller 19 for forming a protective film layer, thereby forming a protective film layer.
form 0.

In this way, a wood-grained decorative board with a lacquer coating layer 16, a wood-grain pattern printing layer 18, and a protective film layer 20 laminated on the surface of the wood base 1 as shown in FIG. 10 will be manufactured. It is.

Effects of the Invention The method for manufacturing a wood-grained decorative board of the present invention has the configuration as described above, and includes forming concave and convex portions with a wood grain pattern on the surface of the bare wood, and then applying lacquer or urethane resin thereon. By layering or applying lacquer on the surface of the bare wood, applying wood grain printing on top of it, and then applying the urethane resin again, you can form a wood grain pattern on the surface of the bare wood. There is.
