Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative material having a three-dimensional pattern.

This invention forms a thick pattern layer of transparent or translucent synthetic resin mixed with colored synthetic resin beads on the surface of a base material, exposes some of the colored synthetic resin beads on the surface of the thick pattern layer, and At least one of the exposed colored synthetic resin beads or the colored synthetic resin beads in the thick pattern layer is smeared to create a design with a three-dimensional and deep pattern due to the synergistic effect with the thick pattern layer and the colored synthetic resin beads. The purpose is to provide excellent decorative materials.

The present invention will be explained below based on embodiments shown in the drawings.

In FIG. 1, plywood with a resin-impregnated paper 1b pasted on the surface of a base plate 1a is used as the base material 1, but in addition to the one shown, other plywoods and
Board materials such as particle board, hard board, gypsum board, pulp cement board, calcium silicate board, calcium carbonate board, plastic board, metal board, etc., and sheets such as paper, synthetic resin sheet, cloth, etc. (hereinafter simply referred to as It is possible to use a sheet with a sheet attached to it or a sheet itself.

A colored layer 2 consisting of a pattern of one color or two or more colors is formed on the surface of the base material 1. Colored layer 2 consists of red iron oxide, iron oxide yellow, phthalocyanine blue,
It is formed by coating or printing a synthetic resin paint containing one or more pigments such as carbon black on the surface of the base material 1, or by pasting a colored sheet on the surface of the base material 1. This colored layer 2 is not necessarily necessary, and if the surface of the base material 1 is to be colored in a desired color when manufacturing the base material 1, for example, when manufacturing a sheet or pulp cement board, the raw material itself may be colored in the desired color. It is unnecessary if there is a

On the surface of the base material 1, in this example the surface of the colored layer 2, there are colored synthetic resin beads 6 of arbitrary shapes such as spherical or oblate spherical, for example, a thick pattern layer 3 of synthetic resin mixed with colored vinyl chloride resin beads. It is formed into a raised shape with a desired planar shape and a desired arrangement. The thick pattern layer 3 is generally formed on the surface of the colored layer 2 by screen printing. The thickness of the thick pattern layer 3 is preferably around 200μ, but is not limited to this thickness. As a synthetic resin,
Transparent or translucent synthetic resins such as acrylic, epoxy, urethane, and polyester are used. This allows the colored layer 2 to pass through the thick pattern layer 3.
can be clearly seen through the thick pattern layer 3, and the colored synthetic resin beads 6 that are freely dispersed in the thick pattern layer 3 in the plane direction and the thickness direction, that is, the colored synthetic resin beads 6 that are three-dimensionally dispersed in the thick pattern layer 3, can be clearly seen. This can enhance the design effect. The colored synthetic resin beads 6 may be transparent or translucent synthetic resin beads whose surfaces are coated with a coloring agent, or synthetic resin beads themselves mixed with a coloring agent. The particle size of the colored synthetic resin beads 6 is
The particle size is preferably 50 to 300μ, but it goes without saying that particle sizes other than this can also be used. The amount of colored synthetic resin beads 6 to be added and the type of color to be added are freely determined in consideration of the design effect. Thick pattern layer 3
After screen printing the raw material paint on the surface of the colored layer 2, it is desirable to apply an antifoaming agent such as a surfactant aqueous solution to the surface. This is because the antifoaming agent has the function of extinguishing the foam in the raw paint and exposing the colored synthetic resin beads 6 in the raw paint to the surface.

Colored synthetic resin beads 6 are on the surface of the thick pattern layer 3.
A part of the thick pattern layer 3 is exposed, and a pattern rich in variation appears on the surface of the thick pattern layer 3. In order to expose some of the colored synthetic resin beads 6 on the surface of the thick pattern layer 3, it is effective to apply the antifoaming agent described above, but after the thick pattern layer 3 has hardened, the thick pattern layer 3 is It is more effective to grind (including polishing) the surface of Through this grinding operation, the entire surface of the thick pattern layer 3 including the colored synthetic resin beads 6 is ground,
Colored synthetic resin beads 6 near the surface of the thick pattern layer 3
can be exposed on the surface.

Note that by applying a solvent that has the effect of causing the colored synthetic resin beads 6 themselves or their surface colorants to bleed, mixed with a sealer or alone on the surface of the thick pattern layer 3 after hardening, the thick pattern layer 3 can be cured. By causing the colored synthetic resin beads 6 exposed on the surface to bleed, a richly varied bleed pattern can be created on the surface of the thick pattern layer 3. In addition, by applying the solvent to the thick pattern layer 3 when it is not yet cured and allowing the solvent to penetrate into the thick pattern layer 3, it is possible to apply the solvent not only to the colored synthetic resin beads 6 on the surface of the thick pattern layer 3 but also to the inside of the thick pattern layer 3. , those in the thick pattern layer 3 can also be blurred to obtain a more varied pattern.

The entire surface of the thick pattern layer 3 and the colored layer 2 is covered with a sealer layer 4 of synthetic resin such as urethane, epoxy, acrylic, aminoalkyd, or the like. The sealer layer 4 is not necessarily required.

Note that a see-through coating layer may be formed on a portion of the sealer layer 4 corresponding to the surface of the thick pattern layer 3, which is dark in the center and becomes lighter toward the outside.

On the surface of the sealer layer 4, an upper transparent coating layer 5 made of a transparent synthetic resin paint such as acrylic, epoxy, urethane, aminoalkyd, or unsaturated polyester is formed. The abrasion resistance of the coating layer 5 may be improved by mixing wear-resistant mineral particles (particle size 10 to 100 μm) such as α-alumina and silicon carbide into the coating layer 5.

The surfaces of the sealer layer 4 and the top transparent coating layer 5 are substantially smooth.

Next, an example of manufacturing a decorative material will be explained.

Production example 1 Urethane enamel mixed with one or more pigments such as red iron oxide, iron oxide yellow, and phthalocyanine blue on the surface of a phenol resin-impregnated paper-attached plywood [solid content excluding pigments and other contaminants (hereinafter simply referred to as solid content)] ) is 52% by weight (hereinafter simply referred to as %)] is 90%

dry for 12 minutes, then apply a urethane-based synthetic resin paint (solid content 45
%) on the surface of the sealer layer at 180g/ ^m2 .
By drying at ℃ for 90 minutes, a desired decorative board was obtained in which the colorant of the colored synthetic resin beads exposed on the surface of the thick pattern layer was smeared.

Production Example 2 As the colored synthetic resin beads in Production Example 1, translucent synthetic resin beads whose surfaces were coated with a coloring agent were used, and instead of adding a solvent that had the effect of causing the colorant to bleed into the sealer, a thick pattern was used. When the layer is uncured, a step of applying a solvent that causes the colorant to bleed onto the thick pattern layer is inserted into the process of Production Example 1 to color the colored synthetic resin beads on the surface and inside of the thick pattern layer. A decorative board made by oozing the agent was obtained.

As described above, according to the present invention, colored synthetic resin beads are mixed in the thick pattern layer of transparent or translucent synthetic resin, so that the colored synthetic resin is three-dimensionally dispersed in the thick pattern layer. By making the beads visible, it is possible to obtain a decorative material with a rich variety of three-dimensional patterns. In addition, because at least one of the colored synthetic resin beads exposed on the surface of the thick pattern layer or the colored synthetic resin beads inside the thick pattern layer is smeared, the design of the decorative material can be improved with a varied mottled smudging pattern. It can be made into a unique design.
