Description

[Detailed description of the invention]

The present invention relates to a method for manufacturing a decorative board, and more particularly to a method for manufacturing a decorative board that has both substantial recesses and visual recesses that match the shape of a pattern to provide a three-dimensional effect close to the real thing and high decorativeness. BACKGROUND ART A wide variety of decorative laminates have been manufactured in which various patterns such as wood grain patterns and geometric patterns are applied to the surface of various decorative laminate base materials such as metal plates, particle boards, plywood, plasterboards, and inorganic fiberboards. Among these, metal plates, which are considered to be the most difficult to apply patterns to, can be used as base materials for decorative laminates by separately creating polyvinyl chloride films, acrylic resin films, etc. with a pattern layer applied by printing. There is a so-called laminate type metal decorative laminate that is bonded to the metal decorative laminate base material mentioned above.The other method is to apply a suitable base coat to the decorative laminate base material to adjust the substrate surface, and then apply gravure offset on top of that. There is a so-called direct print type metal decorative board that is directly printed using a printing method or a screen printing method. The advantages and disadvantages of both are summarized in Table 1 as follows.

〔Example〕

A small rectangular tile pattern is printed using regular ink (A) using a gravure printing method on a transfer paper base made of high-quality paper with a release layer formed on one side using a release process, and the joints of the tiles are coated with liquid-repellent ink. (B) to form a transfer pattern layer. (A) Regular ink acrylic resin binder 100 parts by weight Pigment 200 〃 Toluene (solvent) 750 〃 (B) Liquid repellent ink acrylic resin binder 100 parts by weight Pigment 200 〃 Toluol (solvent) 750 〃 Silica powder (matting agent) 20 〃 Silicone oil (liquid repellent: Shin-Etsu Chemical Co., Ltd. product name)
KP-358) 30 〃 On the other hand, after degreasing and cleaning the surface of an electrogalvanized steel sheet with a thickness of 0.5 mm, a phosphoric acid-based chemical conversion treatment was performed by dipping, and an epoxy resin-based primer manufactured by Toyo Ink Manufacturing Co., Ltd. (product name NMGF1005 primer) was applied using a roll coater and dried at 280°C for 90 seconds to form a primer layer with a thickness of 5 microns. Next, as a base coat, oil-free polyester paint (product product) manufactured by Toyo Ink Manufacturing Co., Ltd.
NMGF3456) was applied twice using a roll coater method and dried at 280°C for 90 seconds to form a semi-dry base coat with a film thickness of 15μ. Thereafter, the transfer paper was pressed to transfer the ink layer of the pattern, and the transfer paper base was peeled off to complete the transfer of the pattern. Next, an oil-free polyester paint (product name NMGF3012) manufactured by Toyo Ink Manufacturing Co., Ltd. was applied once as a top coat layer to the entire surface of the pattern layer using a mesh roll coating method, and then heated at 280°C.
After drying for 90 seconds, the top coat layer was repelled and thinned at the tile joints where the liquid-repellent ink was applied, and that area became matte, resulting in a decorative board with clear recesses. Ta.
