The present invention relates to a gloss transparent and milky white antibacterial glaze and a method of manufacturing ceramics using the same, by adding a silver nano solution to the composition constituting the above-mentioned gloss transparent and milky white antibacterial glaze so that the antimicrobial property is given to the glaze itself. And it is aimed to provide a milky white antibacterial glaze.

1 and 2 is a flow chart of a transparent and milky white antibacterial glaze of the present invention and a method of manufacturing ceramics using the same.

First, a method of manufacturing ceramics using a transparent transparent antibacterial glaze as a first embodiment of the present invention will be described with reference to FIG. 1.

In order to manufacture ceramics using a glossy transparent antibacterial glaze, a molding step (S10) of molding the dough may be performed.

In this case, the dough may be a dough containing at least one of kaolin, clay, sato, ocher and clay.

On the other hand, after the step S10, before performing the step S20 to be described later, may further comprise a drying step of drying the molded product obtained by molding the dough in a shaded and well-ventilated place or drying at a low temperature using a dryer. have.

After the step S10, the first firing step (S20) of heating to a temperature of 700 ℃ to 1000 ℃ can be performed.

Step S20 is a process of baking a molded article by heating the naturally dried molded article at low temperature using an electric furnace or wood fire, etc., so that the glaze is coated on the molded article well in a later stage of application of the glaze before the firing of the conglomerate. At the same time due to the performance of the step S20 it is possible to reduce the breakage rate of the molded article and improve the color development.

After performing the step S20, the seeding step (S30) for oiling the glossy transparent antibacterial glaze in the porcelain was made can be performed.

Meanwhile, the glossy transparent antibacterial glaze used in the step S30 includes feldspar, limestone and barium carbonate as the base raw material and kaolin and silica as the sub raw material, and the silver nano solution in the mixture of the base raw material and the sub raw material described above. It can be configured by adding.

At this time, the combination ratio of feldspar, limestone and barium carbonate (BaCO ₃ ) to be the base raw material is shown in Table 1 below.

feldspar Limestone Barium carbonate 60 20 20

Feldspar is an aluminum silicate mineral containing potassium, sodium, calcium, and barium. It is a major component of granite, and is mainly produced by a series of three single components: potassium feldspar, sodium feldspar, and calcium feldspar. Potassium feldspar, sodium feldspar, calcium feldspar and sodium feldspar form a continuous solid solution, which is collectively referred to as alkali feldspar and plagioclase.

In the present invention, feldspar performs a function of lowering the melting point of the glaze as a flux to help the glaze is fused to the clay surface.

On the other hand, if the content of the above-mentioned feldspar is too small, there is a problem that the glaze does not melt well to form a rough surface or the glaze curling phenomenon, on the contrary, if too much, there may be a problem in the flow and color expression of the glaze.

Limestone is a type of aqueous rock containing calcium carbonate (CaCO ₃ ) as the main component, and is produced by chemical precipitation in seawater or fossils of organisms with carbonate limestone shells. In general, limestone containing 45% or more of CaCO ₃ is mined, and impurities include silicon dioxide, alumina, and magnesia.

The limestone described above in the present invention performs a function of lowering the melting point as a solvent, and also affects glaze surface gloss and flexibility. That is, when the content of the limestone is too small, there is a high risk that the glaze does not dissolve well and the surface of the porcelain is rough after firing.

Barium carbonate is a basic salt of lead carbonate, which is in the form of a colorless powder. It is naturally produced as a poisonous stone and manufactured industrially, and is used as a raw material for optical glass or glaze such as ceramics. As a matting agent, the matte finish is enhanced as a matting agent when used in low glaze, and as a strong flux in high glaze, it has the effect of giving strength and gloss.

On the other hand, silica and kaolin may be added as a sub raw material to the base raw material in order to manufacture a glossy transparent antibacterial glaze in a more stable state.

At this time, the zegel formula (formula 1) of silica and kaolin added to the base material of the glossy transparent antibacterial glaze is as shown in Table 2 below.

Basic neutrality acid 0.1746 KNaO
0.4857 CaO
0.0159 MgO
0.3237 BaO 0.2195 Al ₂ O ₃
0.0011 Fe ₂ O ₃ 1.8974 SiO ₂ … Equation 1

Silica is mainly composed of silicic anhydride (SiO ₂ ) and acts as a skeleton of glaze and forms glass. As a result, the glass itself dissolves only in glass or high temperature, so that it can be mixed with low-temperature feldspar or limestone to produce an appropriate temperature glaze.

Increasing the silica in the glaze increases the melting temperature, increasing the fire resistance, increasing the hardness and strength, and decreasing the expansion coefficient.

Kaolin is represented by Al ₂ Si ₂ O ₅ (OH) ₄ in its basic chemical formula and is also called clay or white clay. As high-purity clay, pure white is often used as the main raw material for ceramics.

The above-described kaolin suspends the glaze slip in the present invention and further performs the function of adhering the glaze slip to the base. On the other hand, the kaolin described above is not preferable because a large amount of yellow spots are formed when the weight exceeds 40%.

On the other hand, the glossy transparent antibacterial glaze of the present invention can be completed by adding a silver nano solution to the base material and the sub-materials described above.

At this time, the silver nano solution is a solution in which silver nano particles are dispersed, and is added to provide antimicrobial activity to the glaze itself. The silver component is harmless to the human body and is not toxic, and it is known to kill 650 kinds of harmful bacteria by inhibiting the metabolic function of the microorganism in various ways. In the present invention, the silver component is responsible for the electrical function of silver ions (Ag +) emitted by silver. By affecting the reproductive function of the microorganism it can be understood that the antimicrobial endowment.

Glossy transparent antibacterial glaze is in a transparent transparent glaze composition having 45.2 to 47.2 mol% of feldspar, 5 to 25 mol% of limestone, 5 to 25 mol% of barium carbonate, 1 to 18 mol% of kaolin, and 4 to 24 mol% of silica. It can be completed by adding 1 to 2 mol% of the solution.

Accordingly, in one embodiment, the above-mentioned glossy transparent antibacterial glaze is mixed with 46.2 mol% of feldspar, 15.4 mol% of limestone, 15.4 mol% of barium carbonate, 8.1 mol% of kaolin and 13.9 mol% of silica to form a glossy transparent antibacterial glaze composition. After that, it can be understood that it can be completed by adding 1 mol% of the silver nano solution to the above-mentioned gloss transparent antibacterial glaze composition.

The antimicrobial test was carried out through the strain test of the glossy transparent antimicrobial glaze thus prepared, and the results are shown in Tables 3 and 4 below.

Test strains: Staphylococcus aureus ATCC 6583P (Inoculation strain 1-Staphylococcus aureus), Escherichia coli ATCC 8739 (Inoculation strain 2-Escherichia coli)

As shown in the above-described strain experiments 1 and 2, the gloss transparent antibacterial glaze of the present invention was able to reduce 99.9% of the inoculated strains 1 (S. aureus) and 2 (E. coli) present in the test piece.

That is, according to the above-mentioned gloss transparent antibacterial glaze can be reduced to 99.9% staphylococcus and E. coli, there is an effect that can be suitably used as a glossy transparent antibacterial glaze.

After performing the step S30, after the above-described drying of the glaze, chaebol firing step (S40) of heating to a temperature of 1100 ℃ to 1300 ℃ can be performed.

S40 step may be understood as a step of high temperature firing to sinter the first baked ceramics.

On the other hand, in the first firing step (S20), drying step and chaebol firing step (S40) of the present invention, the execution time for each step may be the same as the time required in the process of manufacturing ceramics, but may vary depending on the user have.

That is, according to the above-described step S10 to S40, it is possible to manufacture a ceramic having a transparent gloss and at the same time can be completed ceramics given antibacterial.

That is, according to the ceramic manufacturing method using the transparent transparent antimicrobial glaze of the present invention, when applying the transparent transparent antimicrobial glaze to the ceramic, the good properties unique to the ceramic, that is, the effect of environmental hormone does not occur, breathing with fine pores The effect of being able to complete the ceramics having the antibacterial properties of the inoculated strains 1 (Staphylococcus aureus) and the inoculated strains 2 (E. coli) mentioned above while maintaining transparency and smooth milk surface while maintaining food preservation improvement due to the resting action. have.

In addition, according to an embodiment of the present invention, by adding a separate composition does not impart antimicrobial activity to the glaze itself is given antimicrobial, without the hassle of the user to add a separate composition tailored to the glaze at an appropriate ratio There is an effect that can provide an antibacterial glaze given antibacterial.

Next, a method of manufacturing ceramics using the milky white antibacterial glaze that is the second embodiment of the present invention will be described with reference to FIG. 2.

FIG. 2 is a diagram showing triangular coordinates of constituent materials used as base materials of glossy and milky white antibacterial glazes according to one embodiment of the present invention.

According to one embodiment of the present invention, the base material of the glossy transparent antibacterial glaze may be composed of feldspar, limestone and barium carbonate (BaCO 3).

In order to manufacture ceramics using the milky white antibacterial glaze, a molding step (S11) of molding the dough may be performed.

In this case, the dough may be a dough containing at least one of kaolin, clay, sato, ocher and clay.

On the other hand, after the step S11, before performing the step S21, the molded product obtained by molding the dough may be further dried in a shaded and well-ventilated place in a natural drying or drying at a low temperature using a dryer.

On the other hand, step S21 is a process of baking a molded article by heating the naturally dried molded article at a low temperature using an electric furnace or wood fire, etc., so that the glaze is coated on the molded article well in the later oil-based step to apply the glaze before firing the chaebol. At the same time due to the performance of the step S21 has the effect of reducing the breakage rate of the molded article and improve the color development.

After performing the step S21, the milking step (S31) for milking the milky white antibacterial glaze in the porcelain was made can be performed.

Meanwhile, the milky white antibacterial glaze used in step S31 includes feldspar, limestone and talc as the base material, and kaolin and silica as the sub material, and adds a silver nano solution to the mixture of the base material and the sub material described above. Can be configured.

At this time, the combination ratio of feldspar, limestone and talc as the base raw material is shown in Table 6.

feldspar Limestone talc 60 20 20

Feldspar is an aluminum silicate mineral containing potassium, sodium, calcium, and barium. It is a major component of granite, and is mainly produced by a series of three single components: potassium feldspar, sodium feldspar, and calcium feldspar. Potassium feldspar, sodium feldspar, calcium feldspar and sodium feldspar form a continuous solid solution, which is collectively referred to as alkali feldspar and plagioclase.

In the present invention, feldspar performs a function of lowering the melting point of the glaze as a flux to help the glaze is fused to the clay surface. On the other hand, if the content of the above-mentioned feldspar is too small, there is a problem that the glaze does not melt well to form a rough surface or the glaze curling phenomenon, on the contrary, if too much, there may be a problem in the flow and color expression of the glaze.

Limestone is a type of aqueous rock containing calcium carbonate (CaCO ₃ ) as the main component, and is produced by chemical precipitation in seawater or fossils of organisms with carbonate limestone shells. In general, limestone containing 45% or more of CaCO ₃ is mined, and impurities include silicon dioxide, alumina, and magnesia.

The limestone described above in the present invention performs a function of lowering the melting point as a solvent, and also affects glaze surface gloss and flexibility. That is, when the content of the limestone is too small, there is a high risk that the glaze does not dissolve well and the surface of the porcelain is rough after firing.

Talc is a silicate mineral that is soft, glossy and uniquely smooth. When used in glaze, it acts as an emulsion and has the property of changing the glaze into an opaque state.

Meanwhile, in order to manufacture the milky white antibacterial glaze in a more stable state, silica may be added as a sub raw material to the base raw material.

At this time, the zegel formula (formula 2) of the silica added to the base raw material is shown in Table 7 below.

Basic neutrality acid 0.6157 KNaO
0.4662 CaO
0.3682 MgO 0.2107 Al ₂ O ₃
0.0015 Fe ₂ O ₃ 2.2808 SiO ₂ … Equation 2

Silica is mainly composed of silicic anhydride (SiO ₂ ) and acts as a skeleton of glaze and forms glass. As a result, the glass itself dissolves only in glass or high temperature, so that it can be mixed with low-temperature feldspar or limestone to produce an appropriate temperature glaze. Increasing the silica in the glaze increases the melting temperature, increasing the fire resistance, increasing the hardness and strength, and decreasing the expansion coefficient.

On the other hand, the milky white antibacterial glaze of the present invention can be completed by adding a titanium oxide, a natural bone and a silver nano solution to the above-described base raw material and sub raw material.

At this time, titanium oxide (TiO ₂ ) is added as a coloring aid for producing milky white, and may perform a function of emulsifying agent, crystallization in crystal oil, and softening the surface of glaze.

Natural bone ash, which is added to aid the softness of glazes, can also make matte oil when used primarily in milky white glazes.

The silver nano solution is a solution in which silver nano particles are dispersed, and is added to impart antimicrobial activity to the glaze itself. The silver component is harmless to the human body and is not toxic, and it is known to kill 650 kinds of harmful bacteria by inhibiting the metabolic function of the microorganism in various ways. In the present invention, the silver component is responsible for the electrical function of silver ions (Ag +) emitted by silver. By affecting the reproductive function of the microorganism it can be understood that the antimicrobial endowment.

In other words, the antimicrobial activity mechanism using silver ions may be a mechanism by which S-Ag is formed by the reaction of the -SH group of cysteine, which is one of the amino acids constituting proteins such as enzymes, with silver ions to inactivate microorganisms. It binds strongly to -SH, -COOH, and -OH groups of bacteria, destroys the cell membrane of bacteria and disturbs the cells. When silver ions meet with bacteria, they inhibit enzymes that control the respiration of bacteria. This can be suppressed.

More specifically, the milky white antibacterial glaze described above is 37 to 57 mol% of feldspar, 5 to 25 mol% of limestone, 5 to 25 mol% of talc, 10 to 30 mol% of silica, 2 to 4 mol% of titanium oxide, natural bone It can be completed by adding 2 to 4 mol%, and 1 to 2 mol% silver nano solution.

Accordingly, the milky white antibacterial glaze is 47 mol% of feldspar, 13 mol% of limestone, 13 mol% of talc, 20 mol% of silica, 3 mol% of titanium oxide, 3 mol% of natural bone, and 1 mol of silver nano solution. It can be understood that it can be completed by adding%.

The antimicrobial test was carried out through the strain test of the milky white antimicrobial glaze thus prepared, and the results are shown in Tables 8 and 9 below.

Test strains: Staphylococcus aureus ATCC 6583P (Inoculation strain 1-Staphylococcus aureus), Escherichia coli ATCC 8739 (Inoculation strain 2-Escherichia coli)

As shown in the strain test results 1 and 2 described above, the antibacterial glaze of the white glaze of the present invention was able to reduce 99.9% of the inoculated strain 1 (S. aureus) and inoculated strain 2 (E. coli) present in the test piece.

That is, according to the milky white antibacterial glaze, it is possible to reduce the staphylococcus and E. coli 99.9%, and can be used as a milky white antibacterial glaze, and in the manufacture of porcelain, using the milky white antibacterial glaze described above Antibacterial property can be provided by doing this.

After performing step S31, the chaebol firing step (S41) of drying the above-described glaze and heated to a temperature of 1100 ℃ to 1300 ℃ can be performed.

That is, step S41 will be understood as a step of high temperature firing to sinter the first baked ceramics.

On the other hand, in the first firing step (S21), drying step and chaebol firing step (S41) in the second embodiment of the present invention, the execution time for each step is usually the same as the time required in the process of manufacturing ceramics or the user It may vary.

As a result, according to the steps S11 to S41 described above, milky white porcelain can be produced by applying milky glaze, and at the same time, porcelains with antibacterial properties can be completed.

After all, according to the porcelain manufacturing method using the milky white antibacterial glaze of the present invention, when the milky white antibacterial glaze described above is applied to the porcelain, good properties peculiar to the porcelain, that is, the effect of environmental hormone does not occur, breathing with fine pores While maintaining the preservation of food due to the action, etc., while having transparency and smooth cotton, the ceramics having the antimicrobial properties of the inoculated strains 1 (S. aureus) and inoculated strains 2 (E. coli) can be completed. .
