Description

Ceramic surface decoration method and ceramics manufactured using the same {METHOD OF DECORATING CERAMICS SURFACE AND CERAMICS USING THE SAME}

According to the present invention, in the case of general ceramics, since the glaze layer is formed on the surface, there is a side that does not become a breathing bowl. Accordingly, the glaze is removed from the surface and the pattern can be formed on the surface. The earthenware can make full use of the advantages of earthenware, and smoke is built into the pores of porcelain by forming the pattern with smoke, and through this, it has the effect of charcoal built-in, so far infrared ray emission, antibacterial, deodorization, anion generation, humidity control, etc. It relates to a porcelain surface decoration method and a porcelain manufactured using the same.

Conventionally, a method of coloring the first-large pottery using smoke has been applied. This coloration method mainly uses incomplete combustion of sawdust, and the smoke generated by incomplete combustion of sawdust is colored by being introduced into the pores of the first fired base without glaze oil, and the carbon layer in the pores by the inflow of the smoke or lead. This is formed, and a certain pattern can be obtained depending on the degree of inflow, but since the color is expressed only in black, it cannot be used in tile production, and there is a problem that it cannot be widely used in other ceramics. In addition, it is only possible to form a pattern by controlling the area to apply glaze, and for the part exposed to the primary plastic part, distinguish the part where the smoke is colored from the part that is not colored and form the colored pattern by entering the smoke according to the planned design. There is a problem that cannot be controlled.

In particular, in the case of tiles, since the material of the wall of the living space is a material that makes the living space pleasant, the color of black gives a dark and gloomy atmosphere, so that the tile coated with the smoke due to the incomplete combustion is glazed. It has been considered impossible to use because there are too many dark areas without ignition and chaebol firing.

Therefore, the use of glaze, or minimize the use of it, and mainly using the soil to make ceramics, especially tiles to obtain the effects of the natural inherent properties of the soil, such as humidity control, negative ion generation, far-infrared emission, etc. By providing a natural feeling to the mechanical and artificial environment, it is necessary to manufacture ceramics, especially tiles, which can improve the dark and gloomy atmosphere of black color while providing warmth and stability of human emotion.

In particular, in the case of using smoke (smoke) for the main material of such a pattern, since the contents are substantially carbon, it has the same antibacterial and deodorizing effect as the existing charcoal, and thus, a method of manufacturing such ceramics, in particular, a tile is developed. If the effect is really great.

In order to solve the problems of the prior art as described above, the present invention has a surface from which the glaze is removed, and can form a pattern made of carbon bodies on the surface thereof, thereby having all the advantages of earthenware while having an aesthetic expression, and acting as a smoke. It is an object of the present invention to provide a porcelain surface decoration method and a porcelain produced using the same to have a built-in effect of having a charcoal embedded effect.

In order to achieve the above object, the present invention

It provides a ceramic surface decoration method comprising a seventh step of removing the sintered solidified on the surface after the three firing.

The present invention also provides a ceramics produced by the ceramic surface decoration method.

Hereinafter, the present invention will be described in detail.

The present invention relates to a method of decorating porcelain surface, the first step of molding the article into a certain shape for manufacturing porcelain, the second step of the first firing the molded article, the alumina powder on all or part of the surface of the first firing The third step of applying a coating made by dipping in water or an organic solvent and drying, the fourth step of drying after applying a glaze to all or part of the surface of the substrate, and the chaebol firing of the material after the fourth step (sealing step) The fifth step has a configuration comprising a sixth step of firing the three times by the smoke is introduced into the kiln after the chaebol firing step and a seventh step of removing the sintered solid on the surface after the three firing.

In other words, the ceramics are collectively referred to as a ceramic made by baking soil in a kiln, and includes all of various shapes and uses. In other words, this includes all kinds of tiles, tableware, teaware, bowls, ornaments, craft pottery, bathtub, toilet bowl, washbasin, and various other forms. Of course.

Therefore, the first step is to form a substance in a certain shape for manufacturing ceramics, and to form a certain shape to be manufactured by the manufacturer to make a soil, various known molding methods can be applied to this, such as spinning wheel molding, injection Molding, extrusion molding, compression molding, and the like can be applied, and the soil used for this can be used as well as a variety of well-known soil, as well as the far-infrared emission, antibacterial, deodorizing function such as ganban stone, jade, etc. It may be prepared to further include the functional ceramic powder to have the functionality on the porcelain base itself.

The article produced by the above method is subjected to the second step of performing the first firing, which is the primary firing, according to a known method.

In addition, if necessary, the method may further include the step of causing the gloss to be generated on the surface by rubbing the polish after coating it with a predetermined solvent before the initial firing. That is, according to the surface decoration method of the present invention, when the seventh step of finally removing the sintered material is carried out, the surface of ceramics is exposed to the surface of the first fired substrate, in which case the glaze is applied on the surface of the first fired substrate. In order to generate gloss similar to that of sintered, it is preferable to perform such a step before the initial firing.

As a polishing agent for generating such a gloss, a known ball clay commonly used in the art of ceramics may be used, and a representative example of the ball clay is Kentucky Ball Clay # 4. Can be mentioned. That is, when the material formed in the first step is almost dried, the ball clay is dissolved (opened) in a certain solvent such as water or an organic solvent on the surface of the substrate, and then coated or sprayed and then rubbed with melt or the like. Let gloss occur. The gloss in this process appears even after completion without glazing as described above, and gives a glaze-like gloss even without glazing.

In addition, when the ball clay gloss coating agent is added, various colors of pigments may be added to produce gloss having various colors. You can also have it.

In addition, the coating of the gloss coating agent may be made on all or part of the surface of the article, and thus, the part of the finished porcelain surface which is not treated with the gloss coating agent may have a matte surface.

As described above, the formation of the gloss layer not only has the effect of imparting gloss and color, but also has a moisture blocking effect, so that the removal of the sintered material in the case of removing the sintered material in the seventh step is easy. There is also.

This is the process after the first stage firing is completed. In general ceramics production, glazing is applied to the surface. When the glaze is fired after applying the glaze, the glaze melts at high temperatures and adheres to the surface of the substrate. It will have a structure. However, in the case of the present invention, since the glaze is used as a barrier to block smoke, it is used only as a medium for surface decoration. Therefore, after firing the conglomerate, the glaze layer is separated from the substance in the seventh step.

In order to prevent such glaze from adhering to the surface of the substrate and to facilitate separation, an insulating layer having a low reactivity and a high melting point is required. Therefore, in the present invention, in order to form such an isolation layer, a third step of applying a coating made by alumina powder in water or an organic solvent is applied to all or part of the surface of the first calcined substrate, followed by drying. That is, the alumina is a material that is very stable at high temperature as described above, and thus serves to prevent the surface of the glaze and the surface from binding, so that it is applied. In order to make the alumina powder adhere well to the surface of the substrate, it is dissolved in an organic solvent such as water or alcohol, and then applied to the surface of the substrate by spraying, applying, or dipping. The concentration of the coating agent may have a range of values, and preferably a concentration sufficient to be difficult to apply.

The coating area of the coating agent may be coated only on the surface to remove the glaze, so that it may be coated on all or a part according to the design of the ceramics, and when the front coating is applied, the glaze is removed on the whole surface and coated on some surfaces. In this case, the glaze can be removed only at the part where the coating is applied. In addition, such coating of the coating does not necessarily need to coincide with the application portion of the gloss coating, but may be partially coincident or completely coincident depending on the needs of the design.

Next, a fourth step of applying a glaze to all or part of the surface of the substrate and drying it is performed, and in this step, the glaze is not necessarily applied only to all or part of the surface of the substrate coated with the coating agent, regardless of the coating agent. It can be applied to all or part of the surface of the article. Therefore, the glaze of the uncoated portion is combined with the surface of the substrate in the firing of the conglomerate, and the portion of the non-coating agent does not form a bond and is removed in the seventh step, and the smoke can be introduced into this portion.

The glaze to be used in the oiling step may use a glaze having a similar difference in shrinkage rate with the base or a certain glaze during firing depending on the pattern to be formed. That is, the alumina coating layer prevents the glaze from binding to the surface of the substrate, so that even if the glaze melts during firing of the conglomerate, the alumina coating layer does not bind to the substrate. Therefore, during the firing of the conglomerate, 1) when the shrinkage rate is different from that of the base, the glaze shrinks due to its own chemical action, and cracks may be generated by the crack generation according to the shrinkage rate difference. . In other words, organic lines that look like cracks can control the strength and intensity of the black intensity and lines represented by the line by controlling the contraction of the glaze. Glaze has a chemical action that shrinks as it reaches the melting point. Generally, ceramics are manufactured while controlling the contraction of glaze and soil, so that the glaze adheres to the surface of the substrate with almost no cracking. By using the contraction action of the glaze is to express the pattern by infiltrating the smoke generated during incomplete combustion between the cracks of the glaze. Therefore, as the glaze having a large shrinkage ratio is used, a method of generating more cracks may be used, or a method of inducing a large shrinkage by applying a thicker glaze may be used. Therefore, the overall degree of cracking can be artificially adjusted according to the shrinkage and amount of the glaze applied to the substrate. In addition, if the temperature of the conglomerate firing in the fifth step is the temperature at which the glaze boils during firing of the conglomerate, small holes are formed in various places due to the boiling phenomenon of the glaze. The same expression can be used.

2) If the shrinkage rate is similar to that of the product, the glaze is sintered without cracking. If the temperature of the conglomerate firing in the fifth stage is the temperature at which the glaze boils during firing of the conglomerate, the glaze boils. The small hole is formed in the through, it can be expressed as a point having a fine shade expressed as ink on the paper.

Therefore, if the crack or boil occurs, a gap has occurred in the glaze layer, and thus, in the sixth step, the smoke enters these gaps to form a pattern of cracks, dots, or circles. In this case, about 2/3 of the kite is penetrated. On the other hand, if there is no crack, the smoke is not drawn in to prevent the formation of a pattern.

After applying the glaze in addition to the oiling step of the fourth step, it is possible to perform a work of scraping the glaze in a predetermined form consisting of a dot, a line, a face, or a combination thereof, thereby introducing smoke into the scraped portion. This can be done to form a pattern. In this case, when the glaze having a large difference in shrinkage is used as described above, cracks and the pattern may occur together. When the shrinkage is similar, smoke may be introduced according to the scraped pattern without cracking to form a pattern. Can be. In the case of the point can be applied to the method of taking a point with a tool such as an awl, and through this it can be expressed as a point having a fine joke expressed in ink on the paper, and in the case of the line, the awl and so on after glazing You can scrape the glaze according to the design you want with the tool of, and use it to form a linear pattern. In the case of cotton, you can use the method of peeling off the glaze or applying the glaze only on the part except the predetermined surface. Patterns can be formed.

After the coating and drying of the glaze is carried out by the usual method of firing the chaebol, and after the chaebol firing step, the smoke is introduced into the kiln and three firing is performed. The triple firing may proceed to a separate process by completely cooling the kiln after the chaebol firing or by moving the material to a separate kiln, and preferably directly in the same kiln following the fifth step of firing of the chaebol. It is good to proceed by pulling in. This eliminates unnecessary work, such as moving or reheating the kiln, thereby increasing productivity and reducing manufacturing costs.

As a specific example of this, the chaebol firing temperature in general ceramics manufacturing is about 1300 ° C., and after the chaebol firing at such a temperature, the sawdust is added to the kiln at a temperature of 900 to 1100 ° C., preferably 1000 ° C. You may want to fill it up so that there is no space, and close the door of the kiln to block the air. Accordingly, the sawdust put into the kiln is incomplete combustion occurs over a long time, so the smoke generated during the incomplete combustion process penetrates through the cracks or gaps of the glaze layer is expressed with the effect of fine shade like ink.

After the above process, the substrate is subjected to a seventh step of removing the sinter solidified on the surface after firing. The sintered substance to be removed is limited to the alumina and the glaze on the alumina layer. The rest is not removed because the surface of the glaze and the substrate are completely bonded. For the removal, it is preferable to pour water into the substrate or to remove it after being soaked in water to facilitate the removal and to obtain a clean surface.

When the surface sintered product is removed by the above method, only the part with cracks, gaps, or open surfaces penetrates smoke, and the pattern appears. Even though it is an alumina coating layer, the part without gaps in the glaze layer has the surface or gloss of the base material. The surface appears, and the part where the glaze is combined has a configuration in which the glaze surface is preserved as it is.

In another aspect, the present invention provides a porcelain produced by the porcelain surface decoration method as described above, which includes tiles, tableware, teaware, crockery, ornaments, craft pottery, bathtub, toilet, washbasin, various other It includes all forms and is preferably applicable to tiles, tableware, teaware, and craft pottery.

According to the ceramic surface decoration method of the present invention and ceramics using the same according to the present invention, it has a breathable ceramic surface after the first firing that removes it, not glaze on the surface, and uses smoke (lead) generated by incomplete combustion such as sawdust on the surface Thus, the pattern made of carbon can be freely formed to have various designs according to the intention of the producer.

Therefore, after the first firing, the function of breathing far infrared rays, anion generation, humidity control, etc. can be exerted according to the porcelain surface, and the function of generating anion, antibacterial, deodorization, and far infrared rays is achieved through charcoal built-in effect according to pattern formation through lead. Do it.

In particular, the tiles used as interior finishing materials in the interior space are the materials that make up the walls of the interior space, which is a living space. Therefore, in order to make the living space pleasant, the color of black does not form a pattern because it gives a dark and gloomy atmosphere. Tiles coated with smoke due to incomplete combustion have been considered impossible to use because there are too many dark areas without glazing and chaebol firing. There is an advantage to facilitate the production of tiles using the same.
