[Industrial applications]

 The present invention relates to a molded plate having a tile-like or natural stone-like finished surface used for the wall surface or floor surface of a building. In particular, it relates to a molded plate with excellent workability and durability.

[0002]

[Prior art]

 In the finishing of tiles and natural stones on the walls and floors of buildings, natural stones that have been processed into tiles or plates are attached one by one, and joints are provided at the joints, and joints are filled into the joints. The method of doing was generally done. Also, in recent years, in order to simplify the construction, tile-like or natural stone-like patterns are printed on the surface of inorganic or wooden boards, or the seams that have been subjected to these printing processes are used. It was constructed using a decorative plate with a toe.

However, in the case of constructing tiles or plate-shaped natural stones, it takes a lot of time to attach the joints one by one and then the joints are filled with the jointing agent, and the movement such as expansion and contraction of the base material. Due to this, there were drawbacks such as cracking in the joints. Granite has been widely used as a typical stone material as a natural stone. Generally, when a natural stone is processed into a thin plate, it becomes brittle and easily cracked. I needed to do more. Therefore, the plate-shaped natural stone became very heavy, and there was a problem in transportation and construction. In addition, a tile-like or natural stone-like pattern is printed on the surface of an inorganic or wooden board, or a decorative sheet with a sheet applied with these prints does not have a high-class feeling. There was a problem with durability such as the paint or sheet peeling off when exposed to water.

[Problems to be solved by the present invention]

 INDUSTRIAL APPLICABILITY The present invention is intended to provide a tile-like or natural stone-like molded plate that can easily be constructed on a tile-like or natural stone-like wall or floor surface and that has a high-grade feeling and durability. .

[0005]

[Means for Solving the Problems]

 The present invention can achieve the above object by forming joints by forming grooves or notches in a molded plate having a surface layer portion and an inner layer portion having different colors or tones. That is, the inner layer reaches the surface of the molded plate which is made of synthetic resin and inorganic powder and whose surface layer is colored in a color or tone different from that of the inner layer or where the surface layer has a pattern. The grooves of the depth are provided so as to form a grid pattern, a streak pattern, or a mosaic pattern, and at least two adjacent sides of the forming plate are provided with notches having a depth reaching the inner layer portion. Further, the coloring of the surface layer portion is made by the colored resin particles. Further, the pattern of the surface layer portion is given a granite tone.

Hereinafter, the present invention will be described in detail with reference to the drawings. First, FIG. 1 is a schematic sectional view of a tile-like or natural stone-like shaped plate of the present invention. 2 is a perspective view of the forming plate of the present invention in which the grid-like grooves are formed, FIG. 3 is a perspective view of the forming plate of the present invention in which the grooves of a stripe shape are formed, and FIG. 4 is a mosaic tone. FIG. 3 is a perspective view of a molding plate of the present invention in which a groove is formed so as to do so. FIG. 5 is a perspective view of a molding plate of the present invention in which a notch is provided on two adjacent sides of the molding plate. FIG. 6 is a schematic cross-sectional view showing an example in which joints are formed between two adjacent molding plates.

The molded plate (1) is uniformly colored with an inorganic powder or pigment so that the surface layer portion (2) has a different color tone from the inner layer portion (3), or has a marble-like flow pattern or the like. It is colored so that it looks like a pattern. In addition, the molded plate may have a patchy pattern such as a granite tone due to the colored resin particles on the surface layer. Grooves (4) having a depth reaching the inner layer portion (3) are formed in a lattice shape, a streak shape, or a mosaic tone on the surface layer portion (2) of the forming plate (1). Is provided. The molding plate is provided with a notch (5) on at least two adjacent sides.

When the grooves (4) form a lattice shape, it is general that the grooves are formed parallel to the length direction and the width direction of the forming plate, but the present invention is not limited to this. . Further, the groove (4) forming a streak is generally, but not limited to, that the groove is formed parallel to the length direction or the width direction of the forming plate. . Furthermore, that the groove (4) forms a mosaic tone means that the groove serves as a joint portion and tiles or natural stones are combined to form a mosaic pattern. The individual shapes formed by the grooves can be circular, triangular, quadrangular, polygonal, or any shape such as a cross section obtained by cutting natural stone. Therefore, it is possible to combine these in various ways to form a geometric pattern or to stack natural stones.

The notch (5) on the side of the forming plate (1) forms a joint shape at the seam of the forming plate when the forming plates of the present invention are arranged and continuously applied. It should be noted that the notches (5) must be present on at least one of the opposite sides of the adjacent molding plates. For this purpose, it is necessary that at least two adjacent sides of the forming plate have a notch (5).

The shapes of the groove (4) and the notch (5) are not particularly limited, and any shape can be used. For example, in the case of a groove, a V-shape, a U-shape, or an inverted trapezoid is common, and in the case of a notch, an L-shape or a chamfer of a corner is common. Also. The width and depth of the groove and the notch are not particularly limited, and can be appropriately determined depending on the cosmetic properties and the place where the molded plate is used.

As the synthetic resin forming the molded plate, a resin obtained by polymerizing a radically polymerizable unsaturated compound such as a methacrylic acid ester resin, an unsaturated polyester resin, a vinyl ester resin, or an epoxy resin is used.

As the inorganic powder, aluminum hydroxide, aluminum oxide, calcium carbonate, calcium silicate, calcium sulfate, barium sulfate, magnesium hydroxide, titanium oxide, silica, talc, clay, mica, hydroxyapatite, glass, etc. Can be used.

Further, as the coloring material for coloring the surface layer portion or the inner layer portion, a usual inorganic pigment or organic pigment, or a colored resin granule can be used. The inorganic pigment may be replaced by an inorganic powder generally used as a filler. Furthermore, the colored resin granules are granules composed of a synthetic resin, an inorganic filler and a pigment, and are suitable for forming a spot pattern such as a granite tone.

The method for manufacturing the above-mentioned molded plate is not particularly limited, but it is manufactured by the following method. That is, a mixed solution for the surface layer portion and a mixed solution for the inner layer portion, which are composed of a polymerizable compound or an inorganic powder, are injected so as to form two layers, and then they are polymerized and cured. It can be obtained by casting a mixture solution for the inner layer on the gel coat layer and polymerizing and curing. Alternatively, in a mixed liquid composed of a polymerizable compound, an inorganic powder, and a colored resin granule, the difference in specific gravity between the mixed liquid of the polymerizable compound serving as a matrix and the inorganic powder and the colored resin granules is used to It can also be obtained by unevenly distributing the colored resin particles in the surface layer portion and then polymerizing and curing them.

The groove or notch is formed by cutting the surface of the forming plate to a depth that reaches the inner layer portion by a machine such as a router or a circular saw. The groove or notch can also be formed by using a mold having a projection on the inner surface during casting.
