Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a luxurious decorative material with a three-dimensional effect and abrasion resistance. The purpose is to create a decorative board that can be manufactured at a lower cost and can be manufactured from a wide range of materials.

In addition, the scope of application is general to construction materials, furniture boxes, etc., and in particular, it is applied to flooring materials that require surface properties, interior wall materials, ceiling materials, etc. that require a three-dimensional appearance.

As a decorative material having a three-dimensional effect or an uneven appearance, there are conventional methods such as a heat-pressure embossing method, a chemical embossing method using a foaming inhibitor, and a valley printing method.

The hot-pressure embossing method is a method of creating irregularities on the base material by pressurizing and heating using a mold such as an embossing roll or an embossing plate, but it is important that ink does not stick to the convex and concave parts and that the base material is It has the disadvantage that it is impossible to create unevenness in sync with the pattern, and the design is inferior. The chemical embossing method and valley printing method using a foaming suppressant have the disadvantage that the base material is very limited to a film using vinyl chloride resin, and the manufacturing cost is high. Also, from a design perspective, it is difficult to express unevenness in a small area. It also has the disadvantage of poor surface abrasion resistance.

The present invention has been made to solve the above-mentioned drawbacks, and by applying colored ink containing an abrasive to a coating thickness of 50μ or more, three-dimensional appearance and wear resistance can be achieved. The purpose of the present invention is to provide a decorative material that has the following properties.

The present invention will be explained in detail below with reference to the drawings.

The decorative material of the present invention has a structure as shown in FIG. 1, in which 1 is a base material, paper (including resin-mixed paper and synthetic paper) with a basis weight of 20 to 300 g/m ² and a thickness of 0.03〜
1mm vinyl chloride film, acrylic film,
Synthetic resin films such as polyester films, non-woven fabrics, plywood, particle boards, hard boards,
Inorganic boards (gypsum board, pulp cement board, asbestos slate board, asbestos cement board, calcium silicate board, gypsum slag board, etc.), metal board (steel board, stainless steel board, etc.), synthetic resin board (acrylic board, styrene board, etc.) Most of the base materials generally used for building materials can be used, such as synthetic resin decorative boards (melamine, polyester, diallyl phthalate decorative boards, etc.) and composite laminated products of each of these.

2 is a solid layer of a normal multi-colored pattern, and its formation method is solid printing or transfer with opaque colored ink using normal printing methods (gravure, offset, direct, flexo, etc.), colored ground By methods such as coating or pasting with colored film. In some cases, in order to make the most of the base material, the solid layer may be omitted, or a transparent ground coat, a transparent film, etc. may be applied. Further, between the base material 1 and the solid layer 2, a process such as sanding or a sealer can be applied to seal the base material.

Note that if the base material 1 is colored and plays the same role as the solid layer, the solid layer 2 can be omitted.

3 is a pattern, and a flat multicolor pattern can be printed using a normal printing method (gravure, offset, direct, flexo, etc.), or a multicolor pattern can be printed using a pigment transfer method, sublimation dye transfer method, etc. It is formed by a method such as transfer using transfer paper on which a pattern is printed.

4 is a thick embossed pattern, which is printed in thick embossed patterns using a screen printing method or the like using colored ink containing an abrasive so that the thickness of the film is 50 μm or more. This thick embossed pattern is multicolored, and is formed so that at least one color has a difference in coating thickness from other colors.

The inks used are polyester, acrylic, urethane, and vinyl chloride resins, which have a high non-volatile content (40% or more non-volatile content), and use resins that form a hard film when cured as binders, and pigments, dyes, etc. A colored abrasive mixed with 3 to 20 parts by weight of hard abrasive grains such as silicon carbide or fused alumina is used. Further, in order to form a harder coating, it is desirable to use a reaction-curing ink containing two or more liquids.

To create a difference in the thickness of the ink film, for example, when performing multicolor printing using screen printing, by arbitrarily changing the mesh of each plate, the type of ink, the color, the viscosity, etc. 1st color 50~
It is possible to print at 250μ and the second color at 250-1000μ.

Note that a transparent resin layer may be interposed between the pattern 3 and the thick pattern 4 in order to further emphasize the three-dimensional effect.

A transparent resin layer 5 is coated with a colorless or colored transparent synthetic resin paint using a roll coater, flow coater, spray, etc. for surface protection. The resin used is a reaction-curable resin such as polyester, urethane, epoxy, aminoalkyd, acrylic, or vinyl, and has excellent surface properties such as hardness and abrasion resistance. In addition, for extremely hard materials such as flooring materials that require wear resistance, by applying a paint containing 3 to 20 parts by weight of hard abrasive grains such as silicon carbide or fused alumina to the above paint. A decorative material that is extremely hard, has excellent abrasion resistance, and has a three-dimensional appearance and an uneven appearance can be obtained.

[Example 1] Colored tile-like geometric patterns were printed in two colors and opaquely colored solid (3 g/m ² DRY) and a solid print of acrylic primer (2 g/m ² DRY). Next, align the gravure print pattern with the opposite side of the gravure printed film,
A geometric pattern was printed in two colors using a screen printer using an acrylic two-component reaction-curing opaque colored ink containing 5 parts by weight of silicon carbide. By changing the plate mesh and ink viscosity of the first and second colors of screen printing, the first color is 200μ and the second color is
The height was set to 300μ. After printing, it was cured by heating and drying at 70°C for 20 minutes. Next, an epoxy-modified vinyl acetate emulsion adhesive was applied (110 g/m ² ).
The 15 mm thick plywood and the primer surface of the vinyl chloride film were laminated together using a laminator. next,
A decorative board was obtained by applying an acrylic urethane transparent resin paint to the entire surface using a flow coater and a roll coater. The paint is 100 parts by weight of acrylic urethane resin (40% non-volatile content), 15 parts by weight of isocyanate,
Add 8 parts by weight of silicon carbide and appropriate amount of solvent to 150g/m ²
Coated.

As a result, a decorative board with an extremely luxurious tile-like geometric pattern, which is extremely hard and has excellent abrasion resistance, and has a three-dimensional and uneven appearance, was obtained. A decorative board particularly suitable for use as flooring material was obtained.

[Example 2] Opaque colored solid printing (3 g/m ² DRY) and floral abstract pattern 2 were made on 60 g/m ² acrylic resin-impregnated paper using a nitrated cotton-based gravure ink using a rotogravure printing machine. Printed in color. Next, an acrylic modified ethylene vinyl acetate adhesive was applied (80
g/m ² ) 12 mm thick plywood and printing paper were laminated together using a laminator. Next, an abstract floral pattern was printed in two colors using a vinyl acetate-based opaque colored ink containing 7 parts by weight of white alumina using a screen printing machine in register from above the gravure pattern. By changing the plate mesh and ink viscosity of the first and second color in screen printing, the first color can be
150μ, and the height of the second color was 250μ. After screen printing, the ink was cured by heating and drying at 100°C for 20 minutes. Next, apply urethane type 2 using a roll coater.
By applying 120 g/m ² of a liquid reaction curing transparent resin paint, a decorative board with an extremely luxurious floral abstract pattern with excellent surface properties and a three-dimensional effect and uneven appearance was obtained.
