Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the ceramic jewelry manufacturing method and ceramic ornaments according to another embodiment of the present invention.

However, the following will be described by taking the 'ring' as an example of 'ceramic ornaments', but the present invention is not limited to this, and if there is a need to print a pattern on the surface using a transfer paper, other bracelets, earrings, headband and hairpin It is apparent that jewelry can be applied to the present invention.

First, as can be seen through FIG. 1, the ceramic ornament 10 according to the present invention (hereinafter referred to as 'ring' as an example) is produced by compression molding ceramic powder, the surface of the ring circle 11 There are printed various patterns 12, such as a cross.

On the other hand, the ceramic ring 10 as described above, as can be seen through Figure 2, the circular manufacturing step (S10) and the circular manufacturing step (S10) to form a circular ring 11 by compression molding ceramic powder Transfer paper attaching step (S20) for attaching the transfer paper (12a) to the surface of the ring circular 11 produced through the ring circle (11) with the transfer paper 12a attached to the heating furnace to heat the transfer paper (12a) A heat transfer step 30 for printing the printed pattern 12 on the surface of the ring circle and a cooling step 40 for cooling the ring circle 11 on which the pattern 12 is printed.

More specifically, the prototype manufacturing step (S10) is a step of producing a ring prototype 11 (prototype) as shown in Figure 3, the blending step (S11) and the blended ceramic powder to mix the ceramic powder ring Compression molding step (S12) of putting the shape in the engraved mold (S12), the sintering step (S13) of putting the compressed ring circle 11 in the sintering furnace and firing, the width and thickness of the sintered ring circle Forming step (S14, S15) for processing the and finishing step (S16) to trim the surface of the molded ring circle (11).

Here, the mixing step (S11) is a step of mixing the bone powder mixed into the ceramic powder whose main component is zirconia (ZrO2) in a stirrer, compression molding step (S12) is an abnormality in the mold forming the engraved ring shape 11 After filling the ceramic powder blended together, press-molding is performed at a pressure of about 15 to 25 tons.

Sintering step (S13) is a step of firing the ring circular (11) formed in the compression molding step (S12) in the sintering furnace for 20-30 hours at a temperature of about 1200 ℃ to 1600 ℃, preferably 1400 ℃ It is baked for 20 hours at the temperature.

Molding step (S14, S15) is a step of cutting the sintered ring circle 11 to a predetermined width (w) and thickness (t) as shown in Figure 3 to form a ring having an independent function, using a cutter Width processing (S14) step of cutting to a predetermined width (w) and the thickness processing (S15) step of cutting to a predetermined thickness (t) through a CNC lathe or milling operation.

Finishing step (S16) is a step of smoothing the rough surface during the molding step as described above, barrel finishing step (S16a), rough grinding step (S16b) and finishing step (S16c) ).

Here, the barrel finishing step S16a is a step of centrifugal polishing by rotating the abrasive and the ring circle 11 together in a barrel (that is, a barrel) made of hexagonal or octagonal shape, etc., and roughing step (S16b). In the step of rotating the finished ring circle 11 with the primary abrasive to finely polish the primary, the primary abrasive is, for example, a liquid abrasive in which a detergent or the like is mixed with a 300 mesh abrasive. In addition, the finishing step (S16c) is a step for the second fine finishing by rotating the ring circle (11) with the secondary abrasive in order to generate a more precise finishing and gloss. A liquid abrasive mixed with these is used.

Transfer paper attaching step (S20) is a step of attaching the transfer paper 12a to the circle of the ring prepared through the circular manufacturing step (S10), the transfer paper 12a is shown on the lower surface thereof as shown in (a) of FIG. Since precious metals including gold, platinum, or silver are printed in a specific pattern 12 (eg, a cross shape), the pattern 12 is formed on the surface of the ring circle 11 using water as shown in FIG. Adhesion is in contact with this.

In the heat transfer step 30, the ring circle 11 to which the transfer paper 12a is attached is put in a heating furnace, and the pattern 12 printed on the bottom surface of the transfer paper 12a is thermally fused to the surface of the ring circle 11. And the transfer paper 12a itself, except for the pattern 12, is burned off and has a temperature gradient such as between t1 time and t2 time in FIG.

That is, in the thermal transfer step 30, the ring circular 11 to which the transfer paper 12a is attached is placed in a heating furnace, and the pattern 12 made of gold, platinum or silver is continuously raised to a set temperature so that the temperature gradient becomes a straight line. ) Is thermally fused to the surface of the ring circle 11, and the transfer paper 12a is burned (or sublimed) to disappear.

However, in the heat transfer step 30, it is preferable to put the ring circle to which the transfer paper 12a is attached to the heating furnace and to continuously increase the temperature until it becomes 700 ° C to 900 ° C for 1 to 8 hours.

This means that if the temperature in the furnace is raised for too short time of less than 7 hours, the transfer paper 12a is sharply twisted before the pattern 12 is thermally fused so that the pattern 12 is also twisted, and the temperature for a long time longer than 8 hours. This is because the increase in the physical properties of the circular ring 11 of the ceramic material or the appearance may be deformed, as well as the manufacturing time is too long.

At temperatures below 700 ° C., thermal fusion of the pattern 12 made of gold, platinum, silver, etc. is difficult to be achieved, and unnecessary transfer paper 12a is not completely burned away. This is because when the rise of the pattern 12, as well as the ring shape 11 of the ceramic material having a heat resistance of about 1000 ℃ is also deformed.

The cooling step 40 is a step of gradually cooling the ring circle 11 on which the pattern 12 is printed by heating as described above, and has a temperature gradient such as between t2 time and t3 time in FIG. 5. That is, in the cooling step 40, the ring circle 11 on which the pattern 12 is printed through heat transfer is continuously lowered to the set temperature so that the temperature gradient becomes a straight line.

However, the cooling step 40 is preferably a step of gradually lowering the temperature until the internal temperature of the furnace from 100 ° C. or lower for 10 to 14 hours to room temperature, which is a heating furnace for too short time of less than 10 hours This is because if the inner temperature is lowered, the torsion occurs during the rapid cooling of the ring circle 11 that has been heated to a high temperature, and if it cools slowly for an excessively long time exceeding 14 hours, the manufacturing time becomes too long.

Particularly, in the present invention, the temperature in the furnace is gradually lowered from 100 ° C. to below room temperature, but the room temperature is usually 25 ° C., but this is dependent on the season and the surrounding environment. Slow cooling for 12 hours, and slow cooling for 14 hours, such as in summer.

On the other hand, since the ceramic ring according to the present invention has been already described above with reference to FIG. 1 to be manufactured by the method of manufacturing the ceramic ring as described above, a description thereof will be omitted below.

In addition, although the cross shape was described as an example as the pattern 12 printed on the surface of the ring circle 11 as an example, the cross shape is printed in the center as shown in FIG. It is possible to produce a ceramic ring 20 as shown in Figure 6 (b) by using a transfer paper (22a) printed a pattern 22 of various letters, such as Hangul prayer, of course, the other ring circle (11) It will be apparent to those skilled in the art that the ceramic ring 30 printed with patterns 32, such as swastika and Sanskrit, may be manufactured, and thus, a detailed description thereof will be omitted below.

In the above, specific Example of this invention was described. However, the spirit and scope of the present invention is not limited to these specific embodiments, and various changes and modifications can be made without departing from the spirit of the present invention. Those who have it will understand.

Therefore, since the embodiments described above are provided to completely inform the scope of the invention to those skilled in the art, it should be understood that they are exemplary in all respects and not limited. The invention is only defined by the scope of the claims.
