Description

[Detailed description of the invention] The present invention relates to a decorative structure that can be suitably used together with a base for various accessories such as cuff buttons, tie pins, brooches, and pendants. , relates to a decorative structure in which a flat alumina ceramic plate of a specific thickness is provided on a substrate such as a plate-shaped body made of synthetic resin, etc., and has a painted layer painted with a coloring agent and a flux and fired. be.

Conventionally, for example, accessories such as cuff buttons, tie pins, brooches, pendants, etc.
Natural gemstones, imitation gemstones such as artificial rubies and saphires, and ceramics are often used.
Among these accessories, for example, natural gemstones, imitation gemstones, etc. are processed and polished into various beautiful three-dimensional shapes or into flat plate shapes, etc. It is used as a decorative structure by fitting, fastening, pasting, clamping, inserting, attaching, burying, protruding, laying, hanging, etc. Also,
Relatively inexpensive ceramics are made by molding a clay-based composition into a desired shape, painting beautiful patterns on the fired base, and creating metal objects in the same way as natural gemstones, imitation gemstones, etc. The ceramics are provided on a base and used as various decorative structures.

However, when it comes to ceramics, it is extremely difficult to obtain thin, flat ceramics with beautiful paintings that are suitable for accessories. When painting a beautiful pattern on a thin, flat base and firing it, the intended pattern may change or the base may become curved or deformed. Complicated work was required to integrate, attach, attach, and insert the parts into one piece.

Traditionally, in order to make ceramics that fit tightly to the base, for the reasons mentioned above, it was necessary to use thick or hollow-shaped pieces, and accessories using this were extremely heavy. Due to its large volume, there were restrictions on its use as an accessory.

The inventors of the present invention have found that it is possible to create a desired beautiful pattern that could not be achieved with conventional relatively inexpensive ceramics, is thin, and can be easily fitted, pasted, inserted, etc. to a base. As a result of various efforts to obtain accessories that are both flat and lightweight, we were able to solve all the problems encountered with conventional ceramics at once by using thin alumina ceramic plates that have excellent mechanical strength. This led to the completion of the present invention.

The present invention is specifically illustrated in the following figure.

In Figure 1, a flat alumina ceramic plate 2 with a thickness of 0.2 to 2 mm has a painted layer 1 painted with a coloring agent and a flux and fired, which is inserted into a concave base 3. Yes, Figure 2 shows thickness 0.2~
A decorative structure is a 2 mm flat alumina ceramic plate 2 having a painted layer 1 painted with a coloring agent and a flux and fired, which is attached to a flat base 3.

As the substrate 3 used in the present invention, a flat alumina ceramic plate 2 can be fixed, overlapped, fitted, adhered, adhered, clamped, inserted, attached, peripherally mounted, attached, buried, placed, or parallel. As long as it can be installed, connected, protruded, laid, covered, etc., it can be used without any particular restrictions.
For example, the shape of the base 3 may be a triangle, a quadrilateral, a circle, an ellipse, etc. depending on the purpose. The material is not particularly limited, but from the viewpoint of strength, ease of adhesion, lightweight, etc., metals such as iron, aluminum plate, copper plate, tin, etc.;
Wood materials such as wood, plywood, synthetic wood boards, and bamboo; synthetic resins such as thermoplastic and thermosetting resins can be suitably used.

The flat alumina ceramic plate 2 with a thickness of 0.2 to 2 mm used in the present invention is made by first adding various metal oxide powders to alumina powder to obtain a raw material powder, and then adding, for example, polyvinyl alcohol, Add a binder such as butyral resin, a plasticizer such as dibutyl phthalate, a dispersant such as glyceryl monooleate, and a solvent such as methyl ethyl ketone or toluene, and knead with a ball mill etc.
The slip cast method involves making a slurry with a high powder content and forming it into a flat sheet on a smooth support such as a polyester film using a so-called doctor blade, or the slip cast method in which a slurry with a high powder content is formed into a flat sheet using a so-called doctor blade, or a slurry made of alumina powder and metal oxide is used. A binder that decomposes and volatilizes during the firing process is added to the raw material powder, and after being formed by a known method such as a press method in which it is formed into a flat sheet by cold pressing, it is dried and made into a flexible sheet. Let's take a certain raw sheet.

Next, for example, after removing the organic components in the raw sheet by pre-firing, the raw sheet is subjected to main firing at a temperature of 1,400 to 1,800°C in an air or hydrogen stream, and the resulting sheet is shaped into any desired size. Cut to shape, drill holes,
It can be obtained by processing such as division.

However, from the viewpoint of application to cuff buttons, tie pins, etc., the size of the alumina ceramic plate 2 is such that the maximum diameter or side length is 15 mm or less.
3mm or more is better.

Of course, the raw sheet can be processed into any desired shape suitable for the decorative structure according to the present invention, and the alumina ceramic board 2 can also be made through processes such as preliminary firing and main firing.

Therefore, from the viewpoint of the mechanical strength of the alumina ceramic plate 2, the raw material powder containing the alumina powder is a fine powder of 1μ or less, and the amount of metal oxide powder added to the alumina powder is An amount of 20% by weight or less is preferred, particularly an amount of 6 to 2% by weight. Examples of such metal oxide powder include SiO ₂ , MgO, CaO, Ca ₂ O ₃ , MnO, Fe ₂ O ₃ ,
Examples include NiO, CuO, _TiO2, etc., and one or more of these can be used.

Note that the plate 2 needs to have a thickness of 0.2 to 2 mm and be flat from the viewpoint of mechanical strength and lightness as an accessory.

Alumina ceramic plate 2 thus obtained
Next, the plate is decorated with a coloring agent and a flux and fired to form a decorated layer 1. It is preferable that the painted layer 1 is provided on one side of the alumina ceramic plate 2.

Further, an alumina ceramic plate 2 is attached to the base 3.
One may be provided, or two or more may be provided.

Furthermore, if the base 3 is metal as shown in FIG. 1, the alumina ceramic plate 2 is inserted into the base 3, and then the alumina ceramic plate 2 is painted with a coloring agent and a flux, and fired to form a painted layer. 1 may be provided.

In the present invention, "firing" refers to a heating and fusing operation that includes one or more of so-called Yu-yaki, Hon-yaki, and Over-e-yaki. ``Coloring agent'' refers to the pigment used for underpainting, overpainting, overpainting, and ``fluxing agent'' refers to the operation of underpainting, overpainting, and overpainting. A substance that has the effect of promoting melting of a composition such as a pigment at a temperature lower than its melting point.

As the coloring agent which is a component of the painted layer 1, one or more known coloring agents can be used as appropriate depending on the purpose of use of the decorative structure according to the present invention without particular limitation. In view of their affinity with the alumina ceramic plate 2, fine powders of metal oxides such as copper oxide, iron oxide, manganese oxide, cobalt oxide, chloro oxide, and nickel oxide are suitable. Further, the fluxing agent, which is another component, can be used without any particular restrictions in the same way as the coloring agent, but silica, feldspar, coal, soda carbonate, zinc oxide, tin oxide, and barium oxide are preferred. .

An example of a method for providing the painted layer 1 on the alumina ceramic board 2 is as follows.

To obtain the desired color, put the coloring agent and flux into a grinder, add water, grind thoroughly, and dry to make paint. Next, take the paint on a glass plate,
After sufficiently rubbing the "Funori" with a small amount of water, it is applied to a ceramic board 2, the paint is dried, and then fired at 700 to 800°C in an electric kiln to form a painted layer 1.

Alternatively, to decorate with delicate patterns and lines, apply glue, gelatin, etc. on the ceramic board 2 in advance, and then rub a liquid of manganese, cobalt, red pattern, etc. with water on top of this. Draw a line using
It is also possible to provide a painted layer 1 in which a pattern is drawn, colored using the paint, fired, and decorated.

Furthermore, it can also be decorated with gold or silver. Furthermore, if desired, the painted layer 2 can be provided with a covering layer of, for example, a transparent synthetic resin.
