Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a decorative board with an uneven pattern suitable for a decorative board for interior use.

Conventionally, as this type of decorative board, there is a decorative board with an uneven pattern, which is formed by pasting paper with a pattern printed on the surface of a substrate and rolling the surface with an embossing roll.

However, since the printed pattern is provided on both the concave portions and the convex portions of this decorative board, the printed pattern weakens the impression of the uneven pattern and does not provide a deep three-dimensional effect.

Furthermore, conventionally, there is a decorative board with a concavo-convex pattern in which a concavo-convex pattern is formed by rolling an embossing roll on the surface of a substrate, and a pattern is printed on the convex portions.

However, with this decorative board, the printed pattern is provided on the convex portion, so the protruding core of the convex portion is weakened by the printed pattern, and although the printed pattern is not as deep as that on the concave and convex portions. It does not exhibit a certain three-dimensional effect.

In addition, these conventional decorative boards use an embossing roll that presses against the substrate for a short time when forming the uneven pattern, so it is 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 a three-dimensional effect and an excellent aesthetic appearance.

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

The present invention is a further advancement of this own invention, in which the surface of a soft fiberboard is subjected to a base treatment, and the surface is provided with a closed curved pattern surrounding a portion where a convex portion of a desired shape is to be formed, or this closed curved pattern. After the printing ink has dried, a template having a concave portion that matches the area where the convex portion is to be formed is pressed onto the surface of the soft fiberboard, and the convex portion is formed. The portion to be formed is formed into a convex portion, the portion other than the portion where the convex portion is to be formed is formed into a concave portion to form an uneven pattern on the surface, and a closed curved pattern surrounding the convex portion or this closed curved pattern and a desired pattern are provided in the concave portion. This is a method for manufacturing decorative laminates, characterized by manufacturing decorative laminates with a glazed finish.

According to the method for producing a decorative laminate according to the present invention, a decorative laminate can be obtained in which the uneven pattern is emphasized by the printed pattern provided only in the concave portions, especially the closed curved pattern surrounding the convex portions, and which exhibits an excellent aesthetic appearance with a three-dimensional effect. It will be done.

In addition, when forming the uneven pattern, a template that can be kept pressed for a longer time than the embossing roll that rolls the surface is pressed onto the flexible soft fiberboard, so a deep uneven pattern can be obtained. .

Next, examples of the present invention will be described.

A base treatment is applied to the entire surface of the soft fiberboard 1 by pasting white thin paper 2 or applying paint, and after the adhesive or paint dries, a layer is applied to the surface of the soft fiberboard 1 that has been subjected to the base treatment. As shown in Fig. 1, a closed curved pattern 3 surrounding the area where the desired shape of the protrusion is to be formed is printed in gray by silk screen printing, and then a spotted pattern 4 is printed on the area other than the area where the protrusion is to be formed. is printed in the same color or yellow ocher by the same printing method, and after the printing ink dries, water is sprinkled on the surface of the soft fiberboard 1, so that the surface of the soft fiberboard 1, which has increased flexibility, matches the area where the protrusions are to be formed. A template having a concave portion was placed thereon, and the soft fiber board 1 with the template placed thereon was inserted into a press, and the pressure was 20 to 50 kg/CrIt, the time was 30 seconds to 2 minutes, and the temperature was 12
Pressing under conditions of 0 to 170° C. to form an uneven pattern on the surface by forming the portions of the surface of the soft fiberboard 1 where the convex portions are to be formed into the convex portions 5 and the portions other than the portions where the convex portions are expected to be formed into the recessed portions, Convex portion 5
A decorative board is manufactured in which a concave part 6 is provided with a closed curved pattern 3 surrounding the area and a spotted pattern 4.

This decorative board has a closed curve pattern 3 provided only in the recess 6.
The uneven pattern is emphasized by the dotted pattern 4 and the closed curved pattern 3 surrounding the convex part 5 on the bamboo, and the closed curved pattern 3, the spotted pattern 4, and the uneven pattern combine to create an excellent three-dimensional beauty. Suitable for interior decorative boards such as boards and wallboards.

In order to form the uneven pattern, the manufacturing method of this example not only presses a flexible soft fiberboard with a template that can be pressed for a longer time than an embossing roll, but also uses water sprinkling and heating. This increases the flexibility of the soft fiberboard, forming a deep uneven pattern.

In the manufacturing method of this example, in addition to the closed curved pattern 3 surrounding the area where the protrusions are planned to be formed, a spotted pattern 4 located in the area other than the area where the protrusions are planned to be formed is printed on the surface of the soft fiberboard. 4
may have a pattern other than a spotted pattern.

Further, this pattern 4 may be omitted.

[Brief explanation of the drawing]

FIG. 1 is a partial front view of a decorative board manufactured by the manufacturing method of the example, and FIG. 2 is an end view enlarged in the thickness direction of the section cut along the line A-A in FIG. 1: Soft fiberboard, 2: Thin paper, 3: Closed curved pattern, 4: Spotted pattern, 5: Convex portion, 6: Concave portion.

Claims (1)

[Claims] 1. A surface treatment is applied to the surface of the soft fiberboard, and a closed curved pattern surrounding the part where the convex part of the desired shape is planned to be formed, or a desired pattern located in a part other than this closed curved pattern and the part where the convex part is planned to be formed is applied to the surface. After printing and drying the printing ink, a template having a recess that matches the area where the convex part is to be formed is pressed on the surface of the soft fiberboard, and the part where the convex part is to be formed becomes a convex part, and the area other than the part where the convex part is to be formed is made into a convex part. A method for producing a decorative laminate, comprising: forming an uneven pattern on the surface of the concave portion, and producing a decorative laminate in which a closed curved pattern surrounding the convex portion or the closed curved pattern and a desired pattern are provided in the concave portion. .
