The pattern forming step 20 refers to a general technique using a mask on which a pattern is formed, and is not limited to a silk screen mask or a stainless steel screen mask.

As the coating material used in the protective film forming process 60, a general precious metal protective coating agent is used, or a general glaze used in ceramic porcelain production is performed.

When described with reference to the accompanying drawings, preferred embodiments of the present invention 1 to 3 as follows.

FIG. 1 is a manufacturing process diagram of a noble metal tile and a pattern forming method using the noble metal paste of the present invention, and FIG. 2 is a schematic cross-sectional view of a noble metal tile having various patterns manufactured according to the present invention. And, Figure 3 is a photograph of the surface of the product produced by the technology of the present invention.

First, the manufacturing process of the present invention shown in Figure 1 in more detail as follows.

The manufacturing process of the present embodiment is largely noble metal paste manufacturing process (10), mask pattern production process (20), precious metal paste coating process (30), precious metal coating layer firing process (40), surface gloss process (50) and protective film formation Process (60).

The solution mixed in the noble metal paste manufacturing process 10 is 30 to 60 wt% of noble metal powder (gold (Au), silver (Ag) or platinum (Pt)), polymer adhesive (starch, PVA (polyvinylalcohol), PVB (polyvinylbutyrate) ), 1-10 wt% of PVC (polyvinylcloride), PVDF (polyvinylidenfluoride), 5 ~ 20 wt% of ceramic adhesive (glass frit, glass powder, etc.), 1-5wt% of dispersant (NaOH, etc.), solvent (ethanol, acetone) , NMP (N-methylpyrrolidone), DMF (Dimethylformamide) and 10-30 wt%.

In parallel with the noble metal paste manufacturing process 10, a silk screen mask pattern manufacturing process 20 for pattern formation is performed. As for the mesh screen used in the pattern forming process 20, materials such as silk and stainless steel are generally used, and for fabricating a mask, by attaching a tape having a pattern formed on the mesh of fine holes (50 mesh to 500 mesh) Form or apply photosensitizer, sensitize it, remove it in shape, apply oil and dry it. The pattern forming step 20 refers to a general technique using a mask on which a pattern is formed, and is not limited to a silk screen mask or a stainless steel screen mask. Using the mask in this way, it is possible to freely adjust the thickness and shape of the special pattern to be formed later according to the thickness and shape of the manufactured mask.

By using the silk screen mask produced in the silk screen mask pattern manufacturing process (20), the precious metal paste prepared in the precious metal paste process (10), and various kinds of ceramics, ceramic tiles, slabs and metal tiles that are generally available A noble metal paste coating process 30 is performed to apply a noble metal paste to the surface of the tile to form a special pattern. This process results in the formation of several different patterns of precious metal coatings.

In addition, in the case of complex shapes or when multiple precious metals need to be coated at the same time, several masks may be fabricated to perform more than two degrees of coating.

Precious metal paste coating process for coating precious metal on the surface of a common tile (30) is a spray coating method for coating a precious metal paste on the surface of the tile using a spray gun, dip coating method of dipping the tile in the precious metal face solution And painting using a brush can be applied, which can be selectively used according to the working environment.

The tile which has undergone the noble metal paste coating process 30 performs the noble metal coating layer firing process 40. A preferred embodiment of this process is to perform a heat treatment for 5 minutes to 5 hours at a relatively low temperature of about 500 ℃ ~ 800 ℃. In the present invention, heat treatment is possible even at such a low temperature because the noble metal powder is mixed with a ceramic adhesive meltable at a low temperature. It is most preferable to use a general continuous furnace for heat treatment, but other heat treatment equipment may be used. The heat treatment atmosphere may be performed in a general air atmosphere, and in a special case, a special atmosphere gas such as nitrogen or oxygen may be used.

The tile having finished the noble metal coating layer firing step 40 is subjected to a surface polishing step 50 in which the surface is treated with a general metal surface polishing agent. Gold (Au), platinum (Pt), etc. may also specifically omit a gloss process. The polishing agent used in this surface polishing process 50 is performed using a well-known metal polishing agent.

After the surface gloss process 50, the surface protective film formation process 60 is performed for the purpose of protecting surface damage in use. As the coating material used in the protective film forming process 60, a noble metal protective coating agent of a general polymer component is used, or a general glaze or the like used for ceramic porcelain production. Subsequent thermal processes in the case of using glaze as a protective coating are preferably carried out for 5 minutes to 5 hours at 500 ℃ ~ 800 ℃ temperature. By using silver (Ag), gold (Au), or the like as the noble metal, the protective film forming step 60 may be omitted in order to maximize the antibacterial effect on the surface.

On the other hand, as described above, a pattern may be directly formed on a general tile surface by using the noble metal paste coating process 30, and after the noble metal coating layer is formed on the entire surface of the tile, a pattern may be formed thereon. In this case, the lower noble metal coating layer forming process first coats the first noble metal on the entire surface without a mask, and then passes through the same noble metal coating layer firing process 40 as described above, and then again uses a mask to form a noble metal paste coating process for forming a pattern. (30), and the noble metal coating layer firing process 40 for firing the formed pattern.
