First, the ceramic molding 10 according to the embodiment shown in FIG. 1 is coated with a ceramic adhesive (polymer adhesive: 2) on the upper surface of the high melting point ceramic molding 1 formed by molding a ceramic material, and the adhesive On the upper surface of (2), the low melting point ceramics and the Betrossa (3) are deposited, and the upper surface of the low melting point ceramics and the Betrossa (3) is unevenly formed in an uneven form, and the top surface of the low melting point ceramics and the Betrossa (3) The precious metal layer 4 is deposited on the top surface, and a protective film 5 for protecting the precious metal layer 4 is deposited on the upper surface of the precious metal layer 4.

And, the ceramic molding 10 shown in (b) of Figs. 2, 3 and 4 is generally similar to the ceramic molding 10 according to the embodiment described above, but the upper surface of the high-melting point ceramic molding (1) The adhesive 2 to be applied is partially applied to the entire upper surface of the high-melting-point ceramic molding 1 without being applied, and the low-melting-point ceramic and the betrosa 3 are deposited only on the portion to which the adhesive 2 is applied. different.

In addition, the noble metal layer 4 includes the upper surface of the low melting point ceramics and the betrosa 3 and the low melting point ceramics and the betrosa 3 partially coated on the upper surface of the high melting point ceramic molding 1 through the adhesive 2. It is formed by depositing on the upper surface of the uncoated high-melting-point ceramic molding (1), and the smooth surface of the low-melting-point ceramic and the Betrossa (3) is lighted and then polished to the surface of the low-melting-point ceramic and the Betrossa (3). The upper surface of the high-melting-point ceramic molding 1, in which the section 6 is formed and the adhesive 2 is not applied, is formed with a matt portion 7 which does not emit light, and is formed on the ceramic molding 10. The glossy part 6 and the matte part 7 are formed together.

In addition, the noble metal layer 4 is translucent as the noble metal paste composed of the noble metal powder and the solution is deposited in a thin film in one or two embodiments, and the protective film 5 entirely deposited on the upper surface of the noble metal layer 4 is Since the transparent body 6 and the matte portion 7 is visible from the outer surface of the ceramic molding 10, the precious metal layer 4 is seen in the form of irregular bumps.

As shown in the above description, the ceramic molding 10 of one embodiment shown in FIG. 1 and the ceramic molding 10 according to this embodiment shown in FIGS. 2 and 3 are generally similar, but in one embodiment, glossy. Only part is present, but in this embodiment, the matte and light parts 6 and 7 are present together.

As shown in the above description, only the gloss portion is formed in the ceramic molding 10 of the embodiment shown in FIG. 1, and in the ceramic molding 10 of this embodiment shown in FIGS. 2, 3 and 4 (b). Since only the matte-like parts 6 and 7 are formed together and the rest are all the same, a detailed description of the ceramic formation 10 according to this embodiment will be omitted.

The high-melting-point ceramic molding (1) is formed by molding into a shape that conforms to the shape of the ceramic molding to be manufactured as a ceramic material (accessories such as decorative finishing material decorative tiles, beds, mats, decorative or bracelets for bedding), Ceramic materials are commonly referred to as materials such as ocher, kaolin (white clay), silica, fluorite, feldspar (curbstone), talc (talc), alumina, illite (mica), feldspar, germanium, borax, calcium carbonate and bentonite. The ceramic material is mixed in the form of powder, compression molded to the shape as the mixed ceramic powder, and then fired to form a high melting point ceramic molding (1).

At this time, by mixing two or more of the ceramic materials and the melting point control agent to form a high melting point ceramic molding (1), the melting temperature higher than the low melting point ceramics and Betrosa (3) ocher, kaolin (white clay), silica, The high melting point ceramic molding (1) can be formed using any one of ceramics such as fluorite, lead stone (curly stone), talc (talc), and alumina, or a plurality of ceramic materials can be mixed to form a high melting point ceramic molding (1). In this case, in the case of mixing several ceramic materials, a ceramic material having a higher melting temperature than the low melting point ceramics and the Betrosa (3) should be selected.

The reason is that when the low melting point ceramic and the betrosa (3) are heated to melt the low melting point ceramic and the betrosa (3) on the upper surface of the high melting point ceramic molding (1), This is because, when the melting point of 3) is lower than or equal to the ceramic material forming the high melting point ceramic molding 1, the shape of the high melting point ceramic molding 1 serving as a base is damaged.

In the case where several ceramic materials are mixed as described above, the melting temperature of the mixed ceramic material in the state where several ceramic materials are mixed is preferably 1,150 to 1,200 ° C.

For reference, the melting temperatures of the ceramic materials used in the present invention are shown in the table below.

Melting Temperature of Ceramic Materials ocher Kaolin (White soil) burr fluorite 1,250 ℃ 1,650 ~ 1,775 ℃ 1,400 ~ 1,600 ℃ 1270 ~ 1,387 ℃ Feldspar Talc (talc) Alumina Ilright (mica) 1,749 ℃ 1,500 ℃ 2,072 ℃ 900 ~ 1,000 ℃ feldspar germanium borax Calcium carbonate 1,100 ℃ 950 ℃ 760 ° C 825 ℃ Bentonite (clay) Inconsistent high temperature

However, calcium carbonate has no melting point but decomposes at 825 ℃, and bentonite is mixed with various kinds of minerals, so its melting temperature is not constant but high melting point (about 2,200 ℃).

In addition, the low melting point ceramics and the Betrosa (3) refer to a ceramic material having a low melting temperature, and the low melting point ceramics applied to the present invention may be selected by mixing a low melting temperature ceramic such as feldspar having a melting temperature of 1,100 ° C. When the noble metal layer 4 is deposited on the upper surface of the low melting point ceramic 3, the noble metal layer deposited on the upper surface of the low melting point ceramic 3 is smooth. As shown in Fig. 5 and Fig. 6, the opaque and lightless portions 6 and 7 are formed.

The vetrosa is a compound in which silica sand, boric acid, potassium carbonate (soda ash), alumina, limestone, and glass powder are mixed, and selected to have a melting temperature of 900 to 1,000 ° C. and deposited on the upper surface of a high melting point ceramic to be a precious metal layer. Will be formed.

In addition, the material forming the precious metal layer 4 is composed by selecting one of the gold (Au) solution, silver (Ag) solution, platinum (Pt) solution, one of them selected from 75 to 99% by weight And, diluent (thinner) is used by diluting 1 to 25% by weight, a mixture of the noble metal paste and the diluent is called a noble metal paste.

The diluent is a solvent component that dilutes the paste thinly and distributes evenly on the surface of the high-melting-point ceramic molding, and mixes an appropriate amount to obtain a uniform coating on the surface of the high-melting-ceramic molding.

The adhesive (2) is for attaching the low-melting-point ceramic and the Betrosa (3) in the initial powder state to the upper surface of the high-melting-point ceramic molding (1), in the present invention "Minkol (MINKOL) manufactured by" Poongsan Chemical " ), But the adhesive (2) used in the present invention is not limited to the MINKOL product, it is applicable only to the general name of the ceramic adhesive in the art.

Figure 4 is a method of manufacturing the embodiment shown in Figure 1, the manufacturing method is a flexible ceramic molding forming step 101, a flexible ceramic molding firing step 102, the adhesive coating step 103 ), Low melting point ceramic and vetrosa (3) mounting step 104, low melting point ceramic and vetrosa (3) welding step 105, precious metal paste application step 106, precious metal paste firing step (107), and protection The film forming step 108 is performed in sequence.

The flexible ceramic molding forming step 101 is a powdered ceramic material {loess, kaolin (white clay), silica, fluorite, feldspar (stone), talc (talc), alumina, illite (mica), feldspar, germanium, borax, Natural minerals such as calcium carbonate, bentonite, titanium dioxide, and elvan are dried by compression molding at room temperature to form a soft ceramic molding.

In this case, a soft ceramic molding may be formed by mixing two or more melting point regulators in a ceramic material (material shown in Table 1) for molding the soft ceramic molding, and the melting temperature is higher than that of the low-melting ceramic and the Betrosa (3). Loose, kaolin (white clay), silica, fluorite, feldspar (curly), talc (talc), alumina alone may form a soft ceramic molding including a melting point control agent.

Alternatively, in order to expand the functionality of the ceramic materials listed in Table 1, several ceramic materials may be selected and mixed to form a flexible ceramic molding. Even when several ceramic materials are mixed, the melting temperature at which several ceramic materials are mixed is low. The melting temperature should be higher than the melting point ceramics and Betrosa (3).

For this reason, when welding the low-melting-point ceramic and the Betrosa 3 placed on the upper surface of the soft-ceramic molding in the welding step 105 of the low-melting-point ceramic and the Betrossa, the shape of the soft ceramic molding as the base melts, etc. is damaged. This is to prevent it.

At this time, the soft ceramic molding in which the low-melting-point ceramic and the betrosa 3 are welded is plastically processed in the same manner as the soft ceramic molding to form the high-melting-point ceramic molding 1 having a rigid shape like a conventional tile.

After completing the flexible ceramic molding firing step 102 as described above, the adhesive application step 103 of applying the adhesive 2 to the upper surface of the hardened high-melting-point ceramic molding 1 is performed. The adhesive applied at this time uses an adhesive (polymer adhesive) widely used for ceramics.

After the adhesive application step 103 is finished, the adhesive 2 is applied to the upper surface of the high-melting-point ceramic molding 1, and then the low-melting ceramic and the betrosa mounting step 104 is carried out on which the low-melting ceramic and the betrosa 3 are placed. In this step, the low-melting ceramic and the betrosa (3), which is placed on the upper surface of the adhesive (2) by spraying the low-melting ceramic and Betrosa (3) by hand, is not flat, as shown in FIG. The high and low concavo-convex shape, and the lower melting point ceramic and the lower portion of the Betrosa (3) powder is adhered to the adhesive (2), so that the low melting point ceramic and the Betrosa (3) powder are in place without being scattered. .

After the low-melting-point ceramics and the Betrosa (3) powder are placed on the upper surface of the adhesive 2 in the form of irregularities, the low-melting-point ceramic welding step 105 is carried out in which the high-melting-point ceramic molding 1 is put into a heating furnace and heated. In case of using low melting point ceramic as Vetrosa, heating temperature is 900 ~ 1,000 ℃, and when low melting point ceramic is mixed with low melting point ceramic and melting point regulator such as feldspar, it is 1,100 ℃. Heat.

When the heating is started as described above, the adhesive 2 is burned and disappeared, and is melted on the upper surface of the high-melting-point ceramic molding 1 while the low-melting-point ceramic and the betrosa 3 are melted, and the low-melting-point ceramic and The vetrosa 3 is formed in a concave-convex shape with a smooth surface after cooling.

In the low melting point ceramic and the Betrosa welding step 105, the low melting point ceramic 3 starts to melt, and when the low melting point ceramic and the Betrosa 3 are dissolved in a small powder form, heat is removed to minimize heating time.

The removal of the heat is to remove the fire when the internal temperature of the furnace reaches a temperature capable of melting the low-melting point ceramic and the Betrosa (3) when the heating furnace is a closed type, the removal of heat in the closed type is a closed furnace. It means to take out the high-melting-point ceramic molding (1) and to stop the burner and heater of the heating furnace, in the case of a mobile tunnel type, the high-melting-point ceramic molding (1) on which the low-melting-point ceramic (3) is placed The low melting ceramics and the Betrosa (3) in powder form are melted and then welded to the upper surface of the high melting point ceramic molding (1) while the heating time is slightly reduced. Do it enough to melt.

By shortening the melting time of the low-melting point ceramics and the Betrosa 3, the shape of the high-melting-point ceramic molding 1, which becomes a base, does not change, thereby preventing the occurrence of defective products and reducing fuel costs.

After performing the low melting point ceramic and the Betrosa welding step 105 as described above, the high melting point ceramic molding (1) on which the low melting point ceramic and the Betrosa (3) are naturally cooled and then naturally cooled is the high melting point ceramic molding ( The low-melting-point ceramic and the precious metal paste application step 106 of applying the precious metal paste to the upper surface of the Betrosa 3 is performed.

After applying the noble metal paste on the upper surface of the low-melting-point ceramic and the Betrosa (3), the high-melting-point ceramic molding (1) coated with the noble metal paste is put into a heating furnace to carry out the noble metal paste firing step (107). Run

The precious metal paste may be thinly coated on the upper surface of the low melting point ceramic as a spray and a brush because the precious metal solution and the diluent are mixed, and when the noble metal paste firing step 107 is applied, the thickness of the precious metal layer is thin. As a result, the translucent state becomes low, and thus the upper surface of the low-melting ceramic and the low-melting ceramic and the low-melting ceramic which are not deposited by the noble metal layer can be seen through.

As the noble metal layer 4 is formed by depositing a thin film on the upper surface of the low melting point ceramic and the betrosa 3 formed in a smooth glass shape, the surface of the noble metal layer 4 is smooth and gives a glossiness. And as the velcro (3) is unevenly deposited in a concave-convex shape, the noble metal layer (4) is also formed unevenly in a concave-convex shape, the surface is smooth.

In addition, the rugged noble metal layer having a concave-convex shape has a three-dimensional appearance, and as the surface is smoothly formed, diffuse reflection is performed to make the exterior of the ceramic molding 10 beautiful, and the thickness of the noble metal layer is thick. Will be shown.

In addition, the surface is formed in a concave-convex shape so that the protective film 5 is formed on the surface to minimize the wear of the precious metal layer of the ceramic molding 10 in which the precious metal layer 4 is formed.

Next, a protective film forming step 108 is performed, which is a general polymer component for forming the protective film 5 to protect the precious metal layer 4 which is expensive and not high in strength. It is to form a protective film (5) by coating a noble metal protective film agent.

As the material for forming the protective film 5 is that the noble metal protective coating agent of the polymer component is a transparent body, the gloss of the noble metal layer 4 penetrates the protective film 5 so that the entire upper surface of the ceramic molding 10 is polished. In this way, manufacture of the ceramic molding in which the noble metal layer by this invention is formed is completed.

Next, the manufacturing method of this embodiment illustrated in FIG. 6 will be described. The embodiment and the embodiment are similar to each other, but the difference is that as shown in FIGS. Partially deposited, the surface of the low-melting ceramic and the Betrosa (3) is deposited, the glossy gloss portion (6) is formed, and the portion of the low-melting ceramic and Betrosa (3) is not deposited is polished It is different that the matte portion 7 is formed.

Therefore, the manufacturing method of this embodiment is the same as the manufacturing method of one embodiment, as there is no adhesive coating step 103 in the manufacturing method of one embodiment, instead the adhesive pattern forming step 109 is included. The description of the forming step 101, the flexible ceramic molding firing step 102, and the low melting point ceramic and the Betrosa (3) loading step 104 to the protective film forming step 108 are omitted and newly included adhesive patterns are included. Only the forming step 109 will be described.

That is, the adhesive pattern forming step 109 is a shape to be manufactured on the upper surface of the high-melting point ceramic molding 1 hardened through the flexible ceramic molding firing step 102 as shown in FIGS. 6 and 2 and 3. If the adhesive is applied to the screen printing method after placing the screen pattern paper having a hole formed thereon, the adhesive is applied to the upper surface of the high-melting-point ceramic molding 1 while the adhesive penetrates into the minute hole formed in the screen pattern paper. .

When the adhesive is applied to the upper surface of the high melting point ceramic molding 1, the screen pattern paper is separated so that the adhesive is applied to the upper surface of the high melting point ceramic molding 1 to be manufactured.

Then, when the low-melting-point ceramics and the Betrosa loading step 104 are performed, the low-melting-point ceramics and the Betrossa powder in powder form are adhered to and placed only on the portion where the adhesive is applied to the high-melting-point ceramic molding (1). Low melting point ceramics and Betrossa (3) can be partially placed on the upper surface of the), where the low melting point ceramics and Betrossa (3) powder is sprayed by hand and the low melting point is placed on the high melting point ceramic molding (1) The ceramic and the Betrosa (3) are ruggedly placed in the form of irregularities.

Subsequently, the low melting point ceramics and the Betrossa deposition step 105 to the protective film forming step 108 are sequentially executed, so that the low melting point ceramics and the Betrossa 3 are partially unevenly deposited and the matte portions 6 and 7 are formed. Will be able to manufacture the ceramic molding 10 is formed together.
