Description

[0001] The present invention relates to a glaze composition excellent in far-infrared ray emission and antibacterial performance, and a porcelain made using the glaze composition. [0002]

The present invention relates to a glaze composition excellent in far-infrared ray radiation and antibacterial performance, and a ceramic made using the same.

Glaze is a vitreous material used to cover the surface of ceramics. It is a vitreous lye that is applied to make a thin coating on the baked substrate. The purpose of applying the glaze is not only to make the product beautify by giving gloss to the surface but also to increase the strength and to prevent the surface from becoming dirty by making the surface rough. It is also helpful in practical terms to eliminate water absorption and increase resistance to water and chemicals. As the properties of the glaze, the coefficient of thermal expansion is almost the same as that of the base material, and the melting point should be lower than that of the base material. When the ceramic is glazed and baked, it melts well, flows into the glass, and is brought into close contact with the substrate to produce a thin glass film on the surface. When the glaze does not coincide with the expansion and contraction of the substrate, it is peeled or cracked. This crack is called an oil, and some ceramics use it as a decoration.

Glaze is generally transparent, but there are milky oil, colored oil, crystalline oil, blue oil, and cracked oil. The composition of the glaze is different in composition and composition depending on the high and low temperature of the firing temperature and the soil, and is generally classified into magnetic oil and ceramic flow path. The main component of the glaze is a silicate compound. Feldspar, quartz, limestone, kaolin, etc. are used in the case of magnetism which is fired at high temperature (1,200 ~ 1,500 ℃). In the case of pottery which is fired at low temperature (960 ~ 1,000 ℃), kaolin, borax, feldspar, limestone, etc. are used. To add color, metal oxide compounds such as iron, copper, and cobalt are added. In addition, since most of the glazes used for manufacturing celadon are used as chemicals, it is not only a cause of polluting the environment, but also it is not easy to obtain the inherent color or texture of natural ceramics originally intended.

The first aspect of the present invention is a glaze composition excellent in far-infrared radiation and antibacterial performance, characterized by comprising water and a volcanic yarn. The present invention is characterized in that volcanic silica is applied to a glaze and the characteristics of the volcanic silica are applied to a glaze to be expressed.

Volcanic rocks are basalt rocks obtained by crushing basalt. Basalt rock is a rock formed by hardening when magma of 1,200 ° C to 1,400 ° C is eluted from 100km or more underground. These basalt are called volcanic rocks and basalt rocks are called volcanos.

The refractoriness, absorption rate and abrasion rate of the volcanic rock are higher than that of ordinary gravel or sand. Excellent adsorption of heavy metals and excellent toxic removal effect. Particularly, it can be said that it is a weakly alkaline material excellent in indoor air purification effect and excellent in anion and far-infrared radiation dose.

Basalt consists mainly of silicon oxide, aluminum oxide, and iron oxide, and includes titanium dioxide that is not found in clay, jade, elvan, and germanium. In basalt, 3% to 7% of titanium dioxide is present, and titanium dioxide can perform photocatalytic action. This photocatalytic action generates active oxygen, which oxidatively decomposes air pollutants, water pollutants, and odors. These antibacterial, sterilizing, deodorizing and organic decomposing functions are semi-permanent.

As the basalt powders, basalt powders derived from volcanic rocks of Jeju Island can be used. Jeju volcanic rocks are used in real life as follows. Jeju volcanic rocks are used as a natural humidity control tool because it absorbs moisture when humidity is high and releases moisture when humidity is low. The addition of volcanic ash to the aquarium does not cause moss in the aquarium and improves the ability of the fish to heal wounds, and the longer the plants survive, the more they put into plant pots. In addition, putting the volcanic ash in the refrigerator can remove the odor of the refrigerator. In particular, Jeju basalt rocks are known to emit at least 92% of infrared rays at room temperature (below 40 ℃) and generate anions at room temperature. They are also superior in porosity, absorbency and breathability to rocks. The fire resistance is 1,120 캜 to 1,210 캜, the water absorption rate is 17.7% to 32.5%, and the abrasion rate is 47.25% to 67.22%.

Volcanic rocks can have sizes that pass through a 600 mesh sieve. When using a volcanic ash that does not pass through a sieve of 600 mesh, the granules of the volcanic ash can become large, which can form irregularities on the surface of the ceramics and the surface of the ceramics can not be smoothly allowed.

The volcanic ash can be contained in an amount of 10 to 30 parts by weight based on 100 parts by weight of water. When the content of the volcanic ash is less than 10 parts by weight, the phenomenon of flowing down at the time of refluxing is severe and the glaze can not be applied evenly. When the content of the volcanic ash is higher than 30 parts by weight, lumps of volcanic ash may occur and rugged irregularities may be formed on the surface of the ceramics.

A second aspect of the present invention is a method of manufacturing a glaze composition having excellent far-infrared radiation and antibacterial performance, comprising the steps of (i) washing basalt and heat treating the basalt at 100-150 ° C, (ii) pulverizing the heat- (iii) filtering the pulverized product with a sieve of 600 mesh to prepare a volcanic yarn; and (iv) mixing the volcanic yarn with water to prepare a glaze.

First, the basalt can be washed with high pressure water to remove impurities. Basalt rocks with a size of 1 to 25 mm can be washed with high-pressure tap water. It is possible to remove foreign substances and the like attached to the surface of the basalt through the high pressure washing. Basalt is one of the fastest growing types of volcanic rocks that are exposed to the earth by volcanic eruptions, a phenomenon that causes magma to spew out of the ground. Basalt rocks have a high oxygen content and a far-infrared radiation dose, anion emission, promote blood circulation and metabolism, have excellent antibacterial power, strong adsorption power and deodorant power.

Next, the washed basalt can be heat treated to remove moisture. The heat treatment is preferably carried out at a temperature of 100 ° C to 150 ° C. A drying oven may also be used. Because basalt is a porous rock, moisture may be present in the pores of the washed basalt. The presence of such moisture may adversely affect the properties of the glaze in the future, so it needs to be removed. Thus, the water present in the basalt pores can be removed by heat treatment at a temperature above the boiling point of the water.

Next, the dried basalt can be crushed through ball milling using a ceramic ball or the like. The milling process may be performed in two steps. Since basalt is composed of hard minerals, it is first crushed to a size of about 0.3 mm, and then crushed secondarily to obtain a volcanic ash of about 1 μm in size. The finer the particles, the better the potency and advantages of volcanic acid such as far-infrared radiation and antibacterial performance when applied as a glaze to produce ceramics.

Next, the pulverized product is sieved through a 600-mesh sieve to prepare a volcanic yarn. The volcanic acid obtained through the pulverization process can be selected using a sieve, and it is preferable to use a sieve of 600 mesh. When using a volcanic ash that does not pass through a sieve of 600 mesh, the granules of the volcanic ash can become large and unevenness can be formed on the surface of the ceramics, which is not acceptable because the surface is not smooth.

Next, the glaze can be produced by mixing the volcanic ash with water. A feature of the present invention is that only the volcanic acid is mixed with water, and the other additives and the like are not mixed. Even when the volcanic silica is used, it can perform general functions as a glaze, and it is very beneficial to human health because it emits far-infrared rays and exhibits antibacterial properties.

The third aspect of the present invention is a method for producing a ceramics having excellent far-infrared radiation and antibacterial performance, comprising the steps of: (a) mixing water and volcanic acid to prepare a glaze; and (b) The method comprising the steps of:

First, the glaze can be prepared by mixing volcanic yarns with water. You can mix only volcanic rocks with water. Do not mix other additives.

The volcanic rock may be used in an amount of 10 to 30 parts by weight based on 100 parts by weight of water. When the content of the volcanic ash is less than 10 parts by weight, the glaze may not be properly applied due to the phenomenon that the volatilization is carried out at the time of reflux. When the content of the volcanic ash is higher than 30 parts by weight, lumps of volcanic ash may occur and rugged irregularities may be formed on the surface of the ceramics.

The volcanic ash can be prepared by the following process. That is, (i) basalt is washed and heat-treated at 100 ° C to 150 ° C, (ii) the heat-treated basalt is crushed, and (iii) crushed material is sieved through a 600 mesh sieve. The process for preparing the volcanic ash is the same as described above.

Next, ceramics can be produced by applying the glaze thus prepared to an undiluted substrate and then firing it. Application can be done by immersing the unglazed paper in a glaze or glazing the surface of the glaze paper using a brush or the like. Thickening or firing can be carried out according to generally known methods. For example, base paper can be produced using raw clay, ball clay, kaolin, walastonite, etc., and it can be baked at 900 ° C. The firing can be performed in a reducing atmosphere, and firing can be performed at about 1,200 ° C to 1,400 ° C.

The fourth aspect of the present invention may be a ceramics excellent in far-infrared radiation and antimicrobial activity manufactured according to the manufacturing method of the third aspect.

Ceramics according to this aspect have a cover layer in which a volcanic yarn is present on the surface, and far-infrared rays are emitted from the volcanic yarn present therein, and the antibacterial characteristic can be exerted due to inherent characteristics of the volcanic yarn.

If a conventional glaze composition is mixed with a volcanic silica, the far-infrared radiation and antimicrobial properties of the ceramics may not be exhibited. When the existing glaze composition is mixed with the volcanic silica, the components of the existing glaze composition may block all the pores of the volcanic acid or surround the outer surface of the volcanic ash, because the porosity is basically a porous material. This is because it is coated and its own characteristics of volcanic acid are shielded.

In order to solve such problems, the present invention uses only a volcanic acid as a glaze without mixing a conventional glaze composition or an additive.

Hereinafter, the present invention will be described in more detail with reference to Examples.

<Examples>
