Abstract

(57) [Abstract] [Problem] To obtain a stone material in which patterns and characters are expressed so as not to disappear. SOLUTION: The surface of a stone material A is printed with a pattern B and letters written with an inorganic coloring material, for example, ferric nitrate, nickel chloride, cobalt chloride, cobalt sulfate, cobalt nitrate, etc. After coloring, the surface is polished and finished.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a stone material having patterns and characters burned for use on the wall surface, floor surface, interior or various monuments of a building.

[0002]

[Prior art]

 Stone materials such as marble, rhyolite, and granite have been widely used for buildings, etc., but these stone materials differ in color tone depending on the place of production, and excellent ones are expensive, so cheap stone materials are colored or colored. Techniques for dyeing to make it look like an expensive one are disclosed. (See, for example, JP-A-61-14182)

In order to express patterns and letters on stone materials, it is obvious that if they are drawn with paint, they will peel off or disappear due to weathering. Was normal.

[0004]

[Problems to be solved by the device]

 It is not possible to freely express designs and letters with the above-mentioned coloring alone, and there is a risk of discoloration over a long period of time. Moreover, sculpture is not easy, resulting in high cost and difficulty in mass production, making it unsuitable for use on floors and walls of buildings.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a means for causing a desired pattern or character drawn on the surface of a stone material to permeate the surface layer to develop color. In this way, it is possible to obtain a stone material on which patterns and characters are burned, which does not disappear due to abrasion, has excellent weather resistance, does not discolor, and can be mass-produced at low cost.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is to heat and sinter a stone surface on which a pattern or character is drawn with an inorganic coloring material to cause the surface layer to permeate and develop a color, and then to burn the pattern or character on which the surface is finished by polishing. It is a stone material.

[0007] indicating the inorganic colored timber used, ◎ red ferric nitrate a brownish _{[Fe (NO 3) 3 · 6H} 2 O ] nickel chloride [NiCl ₂ · 6H ₂ O] ◎ cobalt chloride as greenish [COCl ₂ · 6H ₂ O] ◎ black, grayish as cobalt sulfate [COSO ₄ · 7H ₂ O] of cobalt nitrate _{[CO (NO 3) 2 · 6H} 2 O ] ◎ other copper nitrate [Cu (NO _{3) 2} · 6H ₂ O] cuprous oxide [Cu ₂ O]

These metal-based inorganic coloring materials are used alone or in combination, and are dissolved in a paste-like or viscous liquid having an appropriate viscosity with a solvent such as water, alcohol, sodium cyanide, borophosphoric acid, and acetone.

There is a case where a stain-proof coating material is applied to a non-colored portion. This stain-proof coating material is made of synthetic resin such as polyester powder, acrylic resin, urethane, etc., silica flux, fluorite powder, talc powder, slaked lime, car Use a pasty or viscous liquid by adding a filler such as powder or pentonite powder.

The inorganic coloring material and the dye-proof coating material can be applied by brush coating, spatula coating, or spraying, or by handwriting with a brush or pen. If the pattern is used, the same pattern is produced in large quantities. It is convenient for

[0011]

【Example】

 Examples will be described with reference to the drawings. FIG. 1 shows a positive representation of a design on the surface of a square stone tile, and FIG. 2 shows a negative representation of the same design.

In FIG. 1, A is a stone material, granite is processed into a square plate, B is a camellia pattern, and a pattern (not shown) obtained by cutting out this pattern B is applied to the surface of the stone material A. the camellia flowers ferric nitrate red-brown _{[Fe (NO 3) 3 · 6H} 2 O ], by applying the inorganic colored timber made of nickel chloride [NiCl ₂ · 6H ₂ O], camellia The leaves are coated with an inorganic coloring material composed of green cobalt chloride [COCl ₂ .6H ₂ O].

When the pattern B is drawn in this way, it is heated and baked at 150 ° to 800 ° C. for 20 to 60 minutes in a far-infrared tunnel furnace (other furnaces may be used) and taken out, and the surface is cooled and then cooled. Finish with a thin polishing finish. The heating temperature and the heating time are adjusted depending on the type and size of the stone material.

FIG. 2 is an example in which the same design as in FIG. 1 is expressed in a negative manner. A pattern paper cut out of the design B is applied to the surface of the stone material A, and a stain-proof coating material is applied with a brush, spatula, or spray. Apply by.

[0015] After curing the resist printing coating material was applied to the pattern B, and the surface cobalt sulfate stone A [COSO ₄ · 7H ₂ O], from cobalt nitrate _{[CO (NO 3) 2 · 6H} 2 O ] When the following inorganic coloring material is applied and fired in the same manner as above, and then the surface is thinly polished to finish, a beautiful surface is obtained in which the pattern B of the camellia is hollowed out in the gray-black background color.

[0016]

[Effect of device]

 The present invention is implemented in the form as described above, and has the following effects.

Beautiful patterns and characters can be expressed by coloring on the surface of the stone material, and since the coloring is made by firing using an inorganic coloring material, it has excellent weather resistance and does not discolor or disappear.

Since the inorganic coloring material penetrates into the surface layer of the stone to a considerable depth by firing, it does not disappear by polishing the surface, and even if it is used on the floor or road surface, it may wear out. It never disappears.

The stone material according to the present invention can be used in a very wide range of interiors and exteriors of buildings, various monuments, arts and crafts, tombs, etc., and contributes to the activation of the stone industry and beautifies the living environment. it can.
