Hereinafter, a preferred embodiment of the present invention and the physical properties of each component will be described in detail, which is intended to describe in detail enough that a person of ordinary skill in the art to which the present invention pertains can easily carry out the invention, This does not mean that the technical spirit and scope of the present invention is limited.

The method of manufacturing a ceramic tile having excellent durability according to the present invention includes a ceramic ink manufacturing step (S101) of manufacturing ceramic ink, a pretreatment step (S101-1) of pretreating the surface of the ceramic tile, and the ceramic ink manufacturing step (S101). A ceramic ink application step (S103) of applying the manufactured ceramic ink to the ceramic tile pretreated through the pretreatment step (S101-1), and a ceramic tile coated with ceramic ink through the ceramic ink application step (S103) A firing step (S105) is performed.

The ceramic ink manufacturing step (S101) is a step of manufacturing a ceramic ink, and is made by mixing modified silicon, heat-resistant pigment, aluminum oxide, silica fume and a solvent, 100 parts by weight of modified silicon, 50 to 200 parts by weight of heat-resistant pigment, 2.5 to 50 parts by weight of aluminum oxide, 2.5 to 25 parts by weight of silica fume, and 75 to 150 parts by weight of the solvent are put into a mixing device equipped with a stirrer and mixed at a speed of 100 to 200 rpm for 5 to 10 minutes. .

The modified silicone acts as a binder and is prepared by polymerizing a silicone resin in a polyester resin. .

50 to 200 parts by weight of the heat-resistant pigment is mixed, and as a pigment having heat resistance (700° C. or higher), it is preferable to use an inorganic colored pigment capable of producing cyan, magenta, yellow, black and green colors.

If the content of the heat-resistant pigment is less than 50 parts by weight, the corresponding color may not be expressed. can

The aluminum oxide contains 2.5 to 50 parts by weight, and it is preferable to use a powder form, and serves to improve the abrasion resistance and the like by improving the compactness of the coating film formed with the ceramic ink.

If the content of the aluminum oxide is less than 2.5 parts by weight, the denseness of the coating film is insufficient, and cracks may occur after the firing step (S105) or curing. There is a possibility that the function of the ink may be deteriorated.

The silica fume contains 2.5 to 25 parts by weight and improves the dispersibility of each component constituting the ceramic ink and serves to adjust the viscosity. If the content of the silica fume is less than 2.5 parts by weight, the above effect is insignificant When the content of the silica fume exceeds 25 parts by weight, the viscosity of the ceramic ink is too low, which is not preferable.

The solvent is contained in 75 to 150 parts by weight, and serves to improve the storability and workability of the ceramic ink. ), butyl acetate (Butyl Acetate, BA) or Cocosol #150 (Kocosol #150, SK Corporation) is preferably made of at least one selected from the group consisting of.

If the content of the solvent is less than 75 parts by weight, the storability and workability of the ceramic ink may be deteriorated. this may be lowered.

The pre-treatment step (S101-1) is a step of pre-treating the surface of the ceramic tile, and consists of a process of radiating a flame of 1200° C. to 2000° C. for 5 to 10 seconds on the surface of the ceramic tile. More specifically, fuel gas (propane , butane, LPG, LNG, etc.) to form a flame showing a temperature of 1200 to 2000 ℃ using a conventional flame-radiating means equipped with a torch, and then radiating it on the surface of the ceramic tile for 5 to 10 seconds made by the process

At this time, the ceramic tile includes γ-aluminum oxide and glass frit, and includes 15 to 60% by weight of γ-alumina and 5 to 20% by weight of glass frit, and it is preferable to use micropores formed on the surface. Do.

The γ-aluminum oxide is more preferably one selected from the group consisting of aluminum nitride, aluminum carbonate, aluminum chloride, aluminum chloride dihydrate, aluminum hydroxide, aluminum chloride and aluminum nitrate is phase-changed.

In general, porous ceramic tiles require a firing process in manufacturing, and tiles can be classified according to the firing temperature range. Usually, it is classified into a polishing tile formed by firing at a temperature of about 1300°C or higher, a porcelain tile formed by firing at a temperature of less than about 1300°C, and a ceramic tile formed by firing at a temperature of about 800°C. It is common that the texture is dense and shows high bending strength.

In the conventional porous ceramic tiles, the firing process was carried out at about 1000° C. or less to create open pores for smooth air in/out, and as a result, compared to general porcelain and polishing tiles, the structure was not dense and the strength was weak. .

Therefore, a certain amount of a glassy material that can act as a binder is added to compensate for this, but as the content of the glassy material increases, the pores through which air enters and exits are blocked and the micropores of the core material exhibiting the humidity control function are blocked, resulting in lowered moisture absorptive and desorptive properties there was a risk of becoming

Accordingly, in the present invention, in order to improve the bending strength of the moisture control tile without lowering moisture absorption and desorptiveness, the content ratio of γ-alumina serving as a moisture control function and glass frit serving as a binder was adjusted in the porous ceramic tile composition, and the porous ceramic tile The silver γ-alumina may include 15 to 60% by weight and 5 to about 20% by weight of glass frit.

The γ-alumina may provide a humidity control function as alumina in a transition state. It is a material that can be transformed into a different structure by heat-treating the aluminum source, and has a large specific surface area and fine pore holes, so it can exhibit excellent properties as a separator, catalyst, catalyst carrier, and adsorbent.

The γ-alumina may be formed on the pore surface included in the porous ceramic tile-forming particles to have excellent moisture control and deodorization functions. Accordingly, when the humidity is high, the γ-alumina absorbs moisture through the pores to lower the indoor humidity, and when the humidity is low, it releases the moisture stored in the pores to increase the indoor humidity. do. In addition, commercial γ-alumina may be used as the γ-alumina, but in terms of cost reduction and efficiency, specifically γ-alumina obtained by phase-transforming an inexpensive aluminum source by heat treatment may be used.

The γ-alumina may include about 15 wt% to about 60 wt%, specifically about 10 wt% to 35 wt%, but when the γ-alumina is less than 15 wt%, it will be difficult to exhibit a sufficient humidity control function. There is a concern, and when it exceeds 60% by weight, the sinterability of the porous ceramic tile is lowered, and thus the strength of the tile may be lowered.

In addition, the glass frit contains 5 to 20% by weight, and when the amount of the glass frit is less than 5% by weight, the plastic strength may be weakened, and when the glass frit exceeds 20% by weight, the manufacturing cost is excessively increased. .

The glass frit is a low-melting glass, which starts to melt at a temperature of about 700° C. lower than the firing temperature of general tiles, facilitates movement between particles in the tile firing process, and acts as an adhesive, that is, a binder to increase the strength of porous ceramic tiles. plays a role

Due to the role of the binder, the glass frit reduces the pores, which are passageways of air between the porous ceramic tile-forming particles, and blocks the pores that exhibit moisture absorptive and desorptive properties on the surface of the porous ceramic tile-forming particles by γ-alumina, thereby reducing moisture absorptive and desorptive properties can do. However, by controlling the content of the glass frit within the above content range, the pores between the porous ceramic tile-forming particles are reduced by the glass frit, and the moisture absorptive and desorptive degradation phenomenon caused by clogging of the pores on the surface of the porous ceramic tile-forming particles can be suppressed. can

In addition, the ceramic tile may contain a remaining amount of a parent material in addition to γ-alumina and glass frit, which is a material serving as a base material constituting the porous ceramic tile, that is, a material serving as a skeleton in the tile. , specifically, may be made of at least one selected from the group consisting of clay, white clay, and loess.

In addition, the ceramic tile may further contain an additive comprising at least one selected from the group consisting of diatomaceous earth, feldspar, porcelain, lime and opacifier, which is contained in an amount of 2 to 5 parts by weight based on 100 parts by weight of the components constituting the ceramic tile. it is preferable

By including the additive composed of the above components, the content of γ-alumina, glass frit, and the parent material can be appropriately adjusted, so that the physical stability of the porous ceramic tile, such as forming strength and plastic strength, and the function of moisture absorptive and desorptive properties can be maintained at a certain level. can be maintained as

After the pre-treatment step (S101-1) consisting of the above process, impurities or moisture remaining on the surface of the ceramic tile are removed, and the ceramic tile exhibits high surface energy (water contact angle of 30° or less), thereby improving adhesion with the ceramic ink. can be improved

At this time, if the flame radiation time is less than 5 seconds, the above effect is insignificant, and if the flame radiation time exceeds 10 seconds, soot may be formed on the surface of the ceramic tile or cracks may occur.

The ceramic ink application step (S103) is a step of applying the ceramic ink prepared in the ceramic ink production step (S101) to the ceramic tile pretreated through the pretreatment step (S101-1), cyan, magenta, yellow, This is done using a reprinting type inkjet printer equipped with 5 color channels made of black and green.

In general, the color management of digital ceramic printing using a reprinting type inkjet printer goes through 4 steps ( Create a New Mode → Ink Restriction → Linearization → Ink Limit ) to present the optimal color combination. In the present invention, as described above for creating a new mode, a ceramic ink made by mixing modified silicon, heat-resistant pigment, aluminum oxide, silica fume and a solvent is applied, and before the profile is applied in the orthodontic device In order to check the color reproduction in the inkjet printer as a step, use the method of performing a single-channel output test with the ink output amount in the range of 100%-0%. The ink output test proceeds with color steps according to the density of 54 inks in each single channel, and the single channel output test checks the color reproducibility according to the color chip smearing phenomenon, sharpness, and ink density during the printing process. .

In addition, conventionally, ceramic ink was output by overprinting, but in the case of overprinting, color bleeding occurs, the color chip sharpness is low, and as the amount of ink output increases, cracks and ink in almost all colors Although the reverse phenomenon occurred, as in the present invention, when ceramic ink is applied using a reprinting type inkjet printer equipped with 5 color channels consisting of cyan, magenta, yellow, black and green, there is no problem as described above and the clarity is excellent. Ceramic tiles can be manufactured.

The firing step (S105) is a step of firing the ceramic tile coated with ceramic ink through the ceramic ink application step (S103), and is performed in a kiln equipped with a primary heating zone, a secondary heating zone and a tertiary heating zone In the first heating zone, the primary firing is performed at a temperature of 590 to 610° C. for 3 to 10 minutes, and the secondary firing is performed at a temperature of 630 to 650° C. in the secondary heating zone for 3 to 10 minutes, the above 3 It is preferable to perform the third firing for 3 to 10 minutes at a temperature of 670 to 690° C. in the primary heating zone.

In the case of the inkjet printing process that prints high-definition images, the management of the equipment (printing system), material (ceramic ink), and operation program (topazlip) as well as the post-production process can have a great impact on the quality of the final product. In the process, discoloration problems may occur due to the symptom that the temperature of the kiln is lowered, or the pigment cannot be melted or carbonized due to the failure to set the appropriate temperature.

The above problem is due to the difference in the temperature of the red color (magenta) before applying the surface glaze to the ceramic tile, and the size of the halftone dots and the color concentration of the ceramic ink in the surface glaze layer show a big difference according to the temperature deviation. In addition, the penetration depth of the ceramic ink is also greatly affected by the temperature deviation. The cause of the different printing characteristics of the ceramic ink according to the temperature deviation of the red color (Magenta) is that the surface remains due to the temperature difference of the red color (Magenta) during the glaze application process. This is because fine pinholes generated by moisture content and evaporation rate affect the dot shape and penetration depth of ceramic ink.

The higher the maximum temperature during firing, the higher the value at which the pigment is fused to the tile. However, if the firing temperature is too high, the pigment may be carbonized. Therefore, it is important to set the initial heating zone entry value and appropriate temperature.

Therefore, in the present invention, as shown in FIG. 4 below, firing is performed using a kiln equipped with a primary heating zone, a secondary heating zone, and a tertiary heating zone, and in the firing step (S105), the primary heating zone Whitening and discoloration of the ceramic ink printed on the ceramic tile occur when the temperature of the
