Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a decorative board used as a countertop or the like and a method for manufacturing the same.

[Background technology]

When using a board made of plywood, Starwood, Bestwood, etc. as a board and pasting a decorative wood veneer on the surface of this board and using it as a decorative board such as a countertop, the decorative wood veneer pasted on the board. Painting is applied to surfaces such as for surface protection. Conventionally, amino-based, urethane-based, and polyester-based paints have been used, but these have problems with scratch resistance, abrasion resistance, heat resistance, fire resistance, and water resistance. There is a problem in that cracks occur on the substrate due to moisture penetration.

[Purpose of the invention]

The present invention has been made in view of the above points, and provides a decorative board that has excellent scratch resistance, abrasion resistance, heat resistance and fire resistance, and is also excellent in water resistance and can reduce the occurrence of deformation. The purpose of this invention is to provide a method for producing the same.

[Disclosure of the Invention]' The decorative board according to the present invention has a decorative layer (2), a spirane resin layer (3) and a surface film (4) laminated in this order from the inner side on the surface of the substrate +1). The method for manufacturing a decorative board according to the present invention is characterized in that: substrate+1
) After forming a decorative layer (2) on the surface, apply spiran resin to this surface, apply a surface film (4) to the surface of this sgolan resin layer, and then heat to harden the spiran resin. The present invention will be described in detail below with reference to Examples.

First, a decorative layer (2) is formed on the surface of the substrate 11), but before forming the decorative layer (2), it is recommended to seal the surface and end surface of the substrate (11) with a white pigment. Good. The decorative layer (2) is made by heat-welding a transfer film, by creating a pattern on the surface of the substrate f1+ using a transfer ink method,
It is formed by gluing decorative wood veneers obtained by slicing precious wood. By applying an astronomical stone-like pattern with a transfer film or transfer ink, you can obtain an astronomical stone-like decorative board, and by using a decorative wood veneer, you can obtain a decorative board between natural wood boards. . In this way, the board (
After applying the decorative layer (2) on the surface of the
) A transparent spiran resin (manufactured by Showa Kobunshi Co., Ltd.) is coated on the surface of the spiran resin (manufactured by Showa Kobunshi Co., Ltd.) at a coating amount of about 10 to 15 f/2 by using a KO-ru coater or a flow coater to form a spiran resin layer (3). Next, a transparent surface film (4) such as a polyethylene film or a polyester film is overlaid on the surface of the Spiran resin layer (3), and heated in this state (applying pressure if necessary) to polymerize the Spiran resin. Let it harden.

In this way, the decorative board A having the structure shown in the figure can be obtained.

In such a decorative board A, the excellent abrasion resistance, inertia resistance, heat and fire resistance of the Sugoran resin makes it possible to impart abrasion resistance, scratch resistance, heat and fire resistance to the decorative board A. Moreover, the excellent water resistance of spiran resin prevents moisture from penetrating into the substrate FTL.
This can prevent warping and deformation from occurring. In addition, spiran resin is inexpensive, and the spiran resin layer +31K gives the decorative board A a sense of weight. The decorative board A exhibits the above-mentioned beauty, such as surface luster, due to the narrow-sided film. A qualitative comparison of the decorative board according to the present invention (Example) and the decorative board using conventional urethane paint (Comparative Example 1) and polyester paint (Comparative Example 2) is as shown in the following table. Become.

In the table above, the products of the present invention have particularly excellent abrasion resistance, and there is no need to add an anti-wear agent.

〔Effect of the invention〕

As described above, in the present invention, the spirane resin layer formed by curing the spirane resin can impart excellent scratch resistance, abrasion resistance, heat resistance and fire resistance to the decorative board, as well as excellent It is capable of imparting water resistance and reducing the occurrence of warping deformation.
