Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a display object made of ceramics that has little wear and does not fade over a long period of time, and a method for manufacturing the same.

Conventional technology Traditionally, natural stones such as Shi granite, white granite, and Aji stone have been used for monument-like stone monuments, tombstones, and nameplates, and letters, patterns, emblems, etc. have been engraved on the surface of the stones. Pigment is applied to the recessed areas to make the coat of arms etc. stand out.

Problems that the invention seeks to solve: However, these natural stones have low hardness, and over many years they weather, making it impossible to distinguish the shapes of uneven parts such as letters, patterns, and emblems, and the pigments applied to the hollow parts also peel off. It will likely have to be repainted every few years.

Therefore, an object of the present invention, in order to solve such conventional problems, is to integrate the display object with one or two FII ceramic materials so that the shape of the uneven part does not collapse due to weathering of the rock. To provide a display object made of ceramics, in which uneven parts carved on the surface of the display object are clearly displayed by different colors, glosses, materials, tones, colors, etc., and a method for manufacturing the same.

Means for Solving the Problems In order to achieve the above-mentioned object, according to the present invention, a display object made of ceramics is made of one type or two of the same or different types.
It is made by gluing, joining, or molding and sintering various ceramic materials, and the uneven parts such as letters, patterns, and emblems engraved on the surface are expressed in different colors, glosses, colors, or tones. It is a feature.

Furthermore, the method for manufacturing a display object made of ceramics of the present invention includes bonding, joining, or molding and sintering one type of ceramic material, or two types of the same or different types of ceramic materials to produce an integrated display object. It is characterized in that uneven parts such as letters, patterns, emblems, etc. are carved on the surface of the object, and these uneven parts are expressed in different glosses, colors, or tones.

In this way, in this invention, a ceramic display object is made by integrating two different or the same ceramic materials by adhesion, joining, or molding sintering, and the characters engraved on the surface are , uneven parts such as patterns, emblems, etc. are displayed with different colors, gloss, colors, materials, tones, colors, etc., so the uneven parts such as letters, patterns, emblems, etc. are clearly displayed, and the display object is made of hard ceramics. Since it is made of material, there is no need to worry about the uneven parts wearing out.

1 and 2 of the drawings show an example of a ceramic display object manufactured according to the present invention, and the display object 1 is composed of a first ceramic member 2 and a second ceramic member 4. has been done. The first ceramic member 2 and the second ceramic member 4 are selected from ceramic materials of different colors, for example, a gold ceramic material and a black ceramic material. The first and second ceramic members 2.4 made of ceramic materials of different colors are formed by bonding pre-sintered plate-shaped pieces with a suitable adhesive or by other means. They are integrated by joining or molding and sintering, thereby producing the display object 1. In particular, it is preferable that the first ceramic material 2 on the front side is made to a required J as shown in the figure, and the surface of such an integrated display object 1 is coated with a method such as sandblasting. Predetermined characters, patterns, emblems, etc. are engraved.

Furthermore, instead of engraving letters, patterns, emblems, etc. by sandblasting on the surface of the first ceramic member 2 on the surface side of the display object 1 in which the first and second ceramic members 2.4 are integrated, it is possible to integrate them. Letters, patterns, emblems, etc. are cut out in advance on the thin first ceramic member 2.
This first ceramic member 2 can also be integrated with the second ceramic member 4 by adhering or joining them.

Furthermore, for the first and second ceramic members 2.4, in addition to ceramic materials of different colors, ceramic materials of the same color but with different tones or shadings, different types of ceramic materials, etc. can be used, and even ceramic materials of the same color can be used. The materials are colored with various ingredients and are layered together during molding, and this molded or calcined body is engraved with letters, patterns, emblems, etc. using sandblasting until it reaches the second layer of ceramics. Later, this can be sintered and integrated to obtain an integrated product. Also, grind the surface of the pit if necessary? 1JI
Ij! It is preferable to do so.

Furthermore, if the entire display object is made of one type of ceramic material and characters, patterns, emblems, etc. are engraved on the surface, the convex parts and the four parts of the uneven parts of the engraved characters, patterns, emblems, etc. can have different colors. It is expressed in luster.

Example (1) Black granules made of titanium nitride based sintered body were prepared at 2゜0x20.
Molding to 0x10xx (press molding machine, pressure crab 0.2
t/cm"), gold-colored titanium nitride granules were placed thereon to a thickness of 2 zm, and pressure molded again (pressure crab 1 t 7 cm2) to obtain a two-layer integrally molded product. This was heat-treated at 1000°C for 30 minutes in nitrogen to obtain a calcined body.A family crest mask was pasted on the golden side of this calcined body, and a pattern was engraved by sandblasting, and the lower layer was also scraped off to an extent of lzz. was sintered in nitrogen at 1800° C. for 1 hour to obtain an integral sintered body.

When this golden side was ground and polished, a wonderful ceramic piece was obtained with a golden family crest embossed on a black background.

Example (2) Granules made by adding blue pigment to alumina were molded into 1 granule using a press molding machine.
Molded into 25X250X25JI tube (pressure crab 0°2t/c
z'), add white alumina granules on top to a thickness of 2u, and pressure mold again (pressure crab 1t/cz2) L
,Ta. A mask with the letters for the nameplate cut out was pasted on top of this molded body, and the letters were engraved using sandblasting until they penetrated into the lower layer. When this was sintered at 1600°C for 3 hours, a beautiful ceramic nameplate with blue letters on a white background was obtained.

Example (3) In Examples (1) and (2> above, the granules were sintered, respectively, and the two were bonded together using an adhesive, thereby producing the same results as in Examples (1) and (2>). The adhesive force φ method like this method gives a product with more flexibility in appearance, but in terms of durability, it is better than Example (1).
, is slightly inferior to an integral sintered body such as (2).

Effects of the Invention As described above, the ceramic display object of the present invention has 1
Because it is made of two types of ceramic materials, which may be the same or different, there is almost no wear on the uneven parts such as letters, patterns, and coats of arms over many years, and the colors do not fade, so the letters always remain intact. The uneven parts of patterns, coats of arms, etc. are clearly expressed in different glosses, colors, or tones, and they stand out clearly in conjunction with the surrounding color to give a three-dimensional effect, and are used to decorate gravestones, stone monuments, etc. It is suitable for displaying characters, emblems, or family crests on nameplates, etc., and has the effect of providing an excellent display object.
