Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board having an uneven pattern in which a printed pattern and minute unevenness are provided only in the concave portions, which is suitable for use as a decorative board for interior decoration such as ceiling boards and wall boards. .

BACKGROUND ART Conventionally, as a decorative board for interior use, there is a decorative board having an uneven pattern with a printed pattern on the entire surface, which is manufactured by adhering paper with a printed pattern on the surface of a substrate and pressing an embossing roll on the surface.

This decorative board has a beautiful appearance due to the printed pattern and the uneven pattern, but since the printed pattern is provided on both the four parts and the convex parts, the printed pattern reduces the three-dimensional effect caused by the uneven pattern, giving it a deep three-dimensional effect. I don't really feel it.

In addition, conventionally, a decorative board having an uneven pattern in which the printed pattern is provided only on the raised parts, which is manufactured by pressing an embossing roll on the surface of the substrate to form an uneven pattern and printing the pattern only on the raised parts of the surface. There is.

However, with this decorative board, the printed pattern is provided on the convex portions instead of the concave portions, so although the printed pattern is not as strong as that of a case where the printed pattern is provided on the entire surface of the concave and convex portions, the printed pattern gives a three-dimensional effect due to the concave and convex patterns. The image quality is reduced, and the deep three-dimensional effect is not felt very much.

Furthermore, in forming the uneven pattern on these conventional decorative boards, an embossing roll is used, which is difficult to keep pressed against the substrate for a long time, making it difficult to form a deep uneven pattern. .

An object of the present invention is to provide a method for manufacturing a decorative board that exhibits an excellent aesthetic appearance with rich three-dimensionality and depth.

The present inventor has already invented a method for manufacturing a decorative board having a concavo-convex pattern in which a printed pattern is provided only in the concave portions to achieve such an object.

The present invention is a further advancement of this own invention, in which the surface of the soft fiberboard is subjected to a base treatment, a pattern is printed on a part of the surface, and after the printing ink dries, the surface of the soft fiberboard is has a convex portion covering the printed pattern portion on the surface thereof, and
A template having fine irregularities is pressed onto the convex portion, and at least the printed pattern portion is shaped into the concave portion, and fine irregularities are formed in the concave portion, so that the printed pattern and fine irregularities are provided only in the concave portion. This is a method for manufacturing a decorative board, characterized by manufacturing a decorative board having an uneven pattern.

The method for producing a decorative board according to the present invention can produce a decorative arm board having an uneven pattern in which a printed pattern and minute unevenness are provided only in the recessed portions, and therefore both the printed pattern provided only in the depressed portion and the fine unevenness. This makes it possible to produce a decorative board that emphasizes the three-dimensional effect of the uneven pattern and exhibits a deep and excellent aesthetic appearance.

Further, when forming the uneven pattern, a template that can be kept pressed for a long time is pressed against the flexible soft fiberboard, so that a deep uneven pattern can be formed.

Next, examples of the present invention will be described.

A white thin paper 2 is glued to the surface of the soft fiberboard 1 or a paint is applied to give a surface treatment to the entire surface. After the adhesive or paint dries, the surface of the soft fiberboard 1 is coated with the material shown in FIG. 1. like,
Spot pattern 3 on part of the surface, mesh pattern 4 on the other part
is printed in an ocher color by silk screen printing method, and after the printing ink dries, water is sprinkled on the surface of the soft fiberboard 1 to form a speckled pattern 3 on the surface of the soft fiberboard 1 with increased flexibility.
A soft fiberboard 1 has a convex portion that matches the mesh pattern portion 4 and a portion 5 of the non-patterned portion, and a template having minute irregularities is placed on the convex portion, and the template is mounted on the template. Insert into the press,
Pressure 30-50 K9/crtl.

Pressing is carried out for 1 to 2 minutes at a temperature of 120 to 150°C to form the speckled pattern part 3, the mesh pattern part 4 and a part of the non-patterned part 5 on the surface of the soft fiberboard 1 into the recessed part 6. Fine unevenness 7 is formed on the bottom surface of the recessed part 6 to produce a decorative board 8 having a deep uneven pattern in which a speckled pattern 3, a mesh pattern 4, and fine unevenness 7 are provided only in the recessed part 6.

In this decorative board 8, the three-dimensional effect of the uneven pattern is emphasized by the spotted pattern 3, the mesh pattern 4, and the fine unevenness 7 provided in the recessed portion 6, and the spotted pattern 3, the mesh pattern 4, the fine unevenness 7, and the uneven pattern are emphasized. Together, they create a deep and excellent aesthetic appearance, making them suitable for interior decorative panels such as ceiling panels and wall panels.

In addition, in forming the uneven pattern, we not only press a template that can be kept pressed for a long time on the flexible soft fiberboard, but also increase the flexibility of the soft fiberboard by sprinkling water and heating. As the surface area increases, a deep uneven pattern is formed.

In the manufacturing method of this example, in addition to the spotted pattern part 3 and the mesh pattern part 4 of the soft fiberboard, a part 5 of the non-pattern part 5 is also formed in the recessed part 6, but only the spotted pattern part 3 and the mesh pattern part 4 are formed. may be formed in the recess.

Further, although the spotted pattern portion 3 and its recessed portion 6 coincide with each other, and the mesh pattern portion 4 and its recessed portion 6 coincide with each other, the recessed portion may be wider than the spotted pattern portion or the mesh pattern portion.

In short, at least the printed pattern portion may be formed in the recessed portion.

In addition, the spacing patterns are spot pattern 3 and mesh pattern 4,
It may be only a spotted pattern, only a mesh pattern, or some other pattern.
