Description

[Detailed description of the invention] The present invention relates to tile-like decorative boards.

Luxury tiles like Italian tiles give a very luxurious and clean impression, but they are expensive and require a lot of work to install, so they are currently only used in some high-end homes. Therefore, as an alternative to these, various tile-like uneven plates have been proposed, but the tile-like uneven boards that have been proposed so far still have room for improvement, as illustrated below. Most likely. For example, as a tile-like decorative board that is easy to install, Datsupui 8 (diaryl phthalate resin Iq) is applied on a substrate such as a flexible board (asbestos cement board) or a special asbestos cement board. Because the tiles are flat, or grooves resembling tile joints are later formed by cutting, it is not possible to express the rounded and smooth texture of the surface side edges of real tiles, and the design It's not good enough.

In this regard, the tile-like I8 existing boards that have been seen in recent years, which are formed by integrally molding melamine on a base material mainly made of aluminum hydroxide and glass fiber, have grooves similar to tile joints formed by pressure forming. Because of this, it is possible to express the rounded and smooth texture of the surface edge of a real tile. Since it is difficult to match the embossing to the pattern of the melamine resin part, in reality, the entire joint part and tile part are simply provided as a plain or nearly plain tile-like sheet.

In addition, a tile-like decorative board has been proposed in which a polyester boat is applied to the printed paper on the base material surface, but in this case as well, the joints of the printed paper and the embossing of the resin layer must be synchronized to allow the movement of the printed paper. There were also problems such as difficulty in forming deep embosses on the resin layer.

In view of the current situation, the present inventor sought to provide a tile-like tile wall board that closely resembles the texture of a tile wall surface in both color tone and three-dimensional shape at a low cost and with good workability, and as a result, the present invention was achieved. It is something.

That is, the present invention provides a noncombustible base material in which grooves resembling tile joints and protrusions resembling tile surfaces having raised patterns are formed by pressure molding; an ink layer formed on the base coat layer located above the tile-like convex portion; and a top coat layer formed entirely on the base coat layer and the ink layer as the top layer. The present invention provides a tile-like decorative board that exhibits a shading pattern depending on the thickness of the ink layer.

The drawings show a tile-like decorative board according to an embodiment of the present invention,
Although this is a sectional view enlarged only in the vertical direction, the present invention will be further described below based on this view. In the figure, 11 is a tile joint-like concave groove formed on the surface of the noncombustible base material 1 by pressure forming, and 12 is a tile surface generated between the tile joint-like concave grooves 11 during the pressure forming. It is a convex part like that.

A raised pattern 13 is further formed on the tile surface-like convex portion 12, but when ink is applied later, a thin ink layer 3 is naturally formed on this raised pattern portion, and the ink is applied to other parts. It is provided so that the layer 3 is formed thickly.

Therefore, it is sufficient that the raised pattern 13 formed on the tile surface-like projection 12 is considerably lower than that of the tile surface-like projection 12, as illustrated in the manufacturing example described later. This also reduces the amount of ink and promotes the formation of a good ink layer 3.

As the noncombustible base material 1, a metal slope can be used in addition to an inorganic board, and when an inorganic board is used, it is a noncombustible material that has good soundproofing and heat insulation effects by itself without being used in combination with other base materials. However, when using an inorganic board as the noncombustible base material 1, when obtaining the inorganic board as a molded product, in other words, it is necessary to The above-mentioned tile joint-like concave groove part 11 and ridge pattern 1
It is necessary to form a tile surface-like convex portion 12 having a shape of 3 by pressure molding.

Examples of inorganic boards suitable as the noncombustible base material 1 in the present invention include poppywood, calcium acid boards, asbestos cement boards, slag gypsum boards, special asbestos cement boards, and gypsum boards.

The base coating layer 2 on the surface of the noncombustible substrate 1 facilitates the formation of the ink layer 3 on top of it, and together with the ink layer 3 and the top coating layer 4' on top of it, it creates a ceramic-like appearance. It is formed to bring about a combination.

In this sense, it is not necessarily necessary to form the base coat layer 2 on the tile joint-like concave grooves 11, and the base coat layer 2 is not necessarily formed on the entire surface of the base material or on the tile face-like protrusions 12 on the noncombustible base material. After that, it is also possible to form a base coating film of another color on the tile joint-like concave grooves 11 in the noncombustible base layer, but partial formation of the base coat layer 2 on the base coat surface is not possible. In order to complicate the work of applying the base paint, a single base coat layer 2 is desirably formed on the entire surface of the substrate.

In forming the base coating layer 2, for example, thermosetting paints such as urethane resin paint, acrylic urethane resin paint, melamine resin paint, aminoalkyd resin paint, epoxy resin paint, synthetic resin emulsion paint, vinyl chloride resin, etc. Paints, thermoplastic resin paints such as acrylic resin paints, acrylic lacquers, and phthalate resin paints, silica-based inorganic paints, and the like can be used as the base paint.

The curtain flow coater method and the spray method are suitable as the method for applying the base paint.

The ink layer 3 is preferably formed by placing a screen ink prepared by mixing a medium such as an acrylic emulsion or an epoxy emulsion with a coloring agent such as a general inorganic or organic pigment on a screen mold, and applying it uniformly using a rubber squeegee. Formed by applying ink and extruding the ink onto the surface of the base material.

The medium is used to give the ink an appropriate viscosity and bond it to the printing surface, and it may also contain thickeners, surfactants, antifoaming agents, etc. to improve screen suitability. . In order to create a shading pattern depending on the thickness of the ink layer 3, the color of the ink layer 3 and the base coating layer 2 must be
The height 1 of the ridges appearing on the base coating layer 2 corresponding to the ridge pattern 13 on the tile surface-like ridges 12 and the thickness m of the ink layer 3 in the depressions between the ridges are Approximately 1. What is necessary is just to make it become milk ZmZI.

This is because if the ink layer 3 is too thick, color shading will not be achieved, and conversely, if the ink layer 3 is too thin, the ink will not drip onto the base coating layer 2 with good reproducibility. The ink layer 3 may be formed entirely on the base coating layer placed above the tile-like convex portion 12, or may be formed partially in a pattern as in the illustrated example.

In forming the top coat layer 4, thermosetting resin paints such as urethane resin paints, acrylic urethane resin paints, melamine resin paints, amino alkyd resin paints, and epoxy resin paints, synthetic resin emulsion paints, and vinyl chloride resins are used. A paint, a thermoplastic resin paint such as an acrylic resin paint, an acrylic lacquer, or a phthalate resin paint can be used as the top coat, and a curtain flow coater method, a spray method, etc. can be applied as the coating method.

As described above, the tile-like decorative board according to the present invention expresses the color of the ink layer as a shading pattern depending on the thickness of the ink layer 3, and at the same time deepens the color of the base coating layer 2 below the ink layer 3. It is designed to be expressed as a certain shading pattern, and furthermore, the transparent or semi-transparent top coat layer 4 expresses the depth and gloss of the tile-like color more than that of real tiles.

In particular, an inorganic noncombustible base material in which tile joint-like concave grooves and tile surface-like protrusions with raised patterns are formed by pressure molding according to the production example described later; A base coat layer formed on the entire surface of the base material; A screen ink layer formed in a pattern on the base coat layer located above the convex portions of both tiles; A screen ink layer formed on the base coat layer and the ink layer as the top layer on the entire surface It consists of the formed topcoat film layer,
A tile-like decorative board that exhibits shading patterns depending on the thickness of the ink layer can be a noncombustible material with excellent design, soundproofing and heat insulation effects, and is also advantageous in its production. .

The present invention will be further explained below with reference to manufacturing examples.

Manufacturing example: 1 out of 3 skins, 0.5 ribs in depth, tile joint-like concave grooves, and 50 mm height raised patterns - a pattern of mountain-shaped raised parts that give an overall appearance similar to melon skin. A fiber-containing slag gypsum board (manufactured by Nikko Kasei Co., Ltd.) with a thickness of 5 ribs was prepared by pressure molding with a tile surface-like convex portion having a Coating amount: 111 (manufactured by Nippon Toyo Co., Ltd.)
In the evening, the entire surface was painted using the curtain flow coater method.

Subsequently, after drying at 10 mm for 15 minutes, cooling and fixing the base coating layer to the surface of the base material, epoxy emulsion medium (manufactured by Dainippon Toyo Co., Ltd.) and a colorant are applied on top of it. A 150r thick screen mold was used to print a silvery blue screen ink at an application rate of 55mm/m2, and then dried at 100°C for 30 minutes to form a base coating film located above the tile-like convexities. An ink layer of maximum thickness (thickness on the concave pattern between the ridges) of 55A was formed on the layer.

Next, urethane resin paint (manufactured by Dainippon Toyo Co., Ltd.) was applied using a curtain flow coater method so that the total amount of coating was equal to 1/2, and dried at 100°C for 15 minutes to apply a transparent top coat to the entire surface of the base material. A coating layer was formed. In this manufacturing example, the ink layer was formed in a cracked pattern, but as a result, the convex parts on both sides of the tile on the target object had a deep shading pattern similar to that of egg shells laid out at 4.0 cm intervals. I was able to express a tasteful texture.

Production Example 2 A tile joint-like concave groove with a middle 3 skin and a depth of 0.5 skin, and a tile face-like convex part with a raised pattern of 80 r in height similar to Production Example 1 were formed by pressure molding. A flexible board (asbestos cement board manufactured by Nikko Kasei Co., Ltd.) with a thickness of 3 ribs was prepared, and an ivory white acrylic urethane resin paint (manufactured by Dainippon Toyo Co., Ltd.) was applied to the surface in an amount of 111 μm/cm. The entire surface was coated using the curtain flow coater method.

Subsequently, after drying at 100°C for 10 minutes and cooling to fix the base coating layer on the surface of the base material, a brown color consisting of acrylic emulsion medium (manufactured by Dainippon Toyo Co., Ltd.) and a coloring agent was applied on top of it. Screen ink was printed using a screen mold with a thickness of 200 cm to give a coating amount of 110 cm/ink, and then dried at 100°C for 20 minutes to coat the base coating layer located above the tile-like convexities. Then, an ink layer with a maximum thickness of 80 mm was formed.

Next, amino alkyd paint (manufactured by Dainippon Toyo Co., Ltd.) was applied using a curtain flow coater method at a coating rate of 88 coats/day, dried at 100°C for 10 minutes, and a transparent top coat was applied to the entire surface of the base material. A coating layer was formed. In this production example as well, the ink layer was formed in a cracked pattern, and as a result, a tile-like decorative board with good quality in the production example Hakamaken was able to be obtained.
