Description

Resin-added ceramics and its manufacturing method {Resin-comprising Ceramics and manufacturing method

The present invention relates to porcelain with a resin added thereto and a method for manufacturing the same, and more particularly, to a method for designing and manufacturing porcelain using a resin that is difficult to utilize or handle easily in the design and manufacturing process of the porcelain, and to a porcelain produced through the same. .

Porcelain refers to a product that is formed by heating or sintering an inorganic material such as clay, feldspar, silica, or pottery alone or mixed. In Korea, the culture of ceramics is especially developed among oriental countries, and the kinds of ceramics are also known to be very diverse. Recently, for the internationalization of Korean ceramics, a new type of ceramic design reflecting the tastes and needs of domestic and foreign customers has been released. In addition to the inorganic materials traditionally used in the manufacture of ceramics, there is a growing interest in composite ceramic products utilizing wood, glass, metal, and other organic or inorganic materials.

However, there are actually many difficulties in adding other materials in addition to the inorganic materials such as clay mentioned above in the process of making pottery. The purity and crystal structure of the dough can be easily disturbed by adding materials other than clay, which is the basic material of ceramics, and the properties of other materials, such as clay, through the process of priming and chaebol in a kiln with high temperature of 1000 ℃ or higher. This is because the shape may be deformed or destroyed. In addition, pottery is generally subjected to a chaebol process of glazing and baking again in the kiln to increase the preservation and glossiness, there is also a problem that can cause unintended reaction between other materials and glaze under high temperature conditions.

In particular, among other materials, the resin is very sensitive and the melting point is relatively low, so the possibility of complex application in ceramics manufacturing is not high. Even if the resin is to be used for ceramic design as the other material, the influence of each stage of ceramic dough, molding, priming, conglomerate, and finishing on the resin's physical properties is unclear, and the resin component added to the ceramic is effectively fixed and cured. There is a real problem with the technique.

Under this background, the present inventors have made efforts to solve the above problems. As a result, the present invention provides a novel ceramics in which resin is stably fixed and cured on the surface, bottom, or inside of ceramics made of inorganic materials, and a method of manufacturing the same. The present invention has been completed by the invention.

This will be described in detail below. Meanwhile, each of the descriptions and the embodiments disclosed in the present invention may be applied to each of the other descriptions and the embodiments. That is, all combinations of the various elements disclosed in the present invention fall within the scope of the present invention. In addition, the scope of the present invention is not to be limited by the specific description described below.

One aspect of the present application for achieving the above object provides a method for producing a ceramic product.

The ceramic product manufacturing method of the present invention, specifically the first step of preparing a ceramic having a groove or a surface to which the resin can be added as a ceramic that went through the first and chaebol process, by adhering a film to the periphery of the groove or surface A second step of making a mold to fix the shape of the resin to be added, a third step of adding resin to the space between the groove or face of the porcelain and the mold, and a fourth step of curing the added resin do.

The first step is to prepare a ceramic having a specific shape of the groove or surface to which the resin can be added, manufacturing a ceramic prototype using a mold made of gypsum and soil (slip), removed from the plaster mold It may comprise the step of drying the pottery, priming and chaebol.

In the present invention, "pottery" refers to a product that is molded by heating alone or mixed with inorganic materials such as clay, feldspar, silica, or pottery, and then sintered by heating. The type of ceramics may include, but is not limited to, white porcelain, celadon, and powder blue dust according to the type of soil, soil, and slip. In addition, ceramics are classified into earthenware, pottery, stoneware, porcelain, etc. according to the baking temperature, and the ceramics of the present invention means all kinds of ceramics. Pottery has the same meaning as ceramics and porcelain products, and the porcelain products of the present invention are products such as jars, incense burners, as well as kitchen containers such as cups, water cups, wine glasses, vases, wine bottles (main bottles), bowls, plates, and bowls It may also include, but is not limited thereto.

The shape of the groove or surface of the porcelain surface to which the resin may be added is not particularly limited, and a structure in which a liquid resin may be placed and hardened on the surface, side, bottom, or top of the porcelain may be sufficient. Such grooves or surfaces may be shaped by hollowing and carving while shaping the shape of the ceramics at the stage before the first step.

The second step is to shape the frame made of film on the surface of the ceramic product so that the resin to be added to the ceramics can be stably and precisely positioned.

In the present invention, the term "resin" is also referred to as a "resin," and refers to an amorphous solid or semisolid composed of an organic compound and its derivatives, and is divided into a natural resin and a synthetic resin. The resin of the present invention includes both an epoxy resin mainly used for producing prototypes and a non-foaming urethane resin used for casting by pouring into a mold. In addition, the resin used in the present invention may be transparent or may have a unique color or gloss. Therefore, when added to the surface of the ceramic products, it can be combined with the color of the ceramics to bring out a unique aesthetic.

The second step includes bonding the film to the periphery of the groove or face of the porcelain, the film is not limited to the kind, but may be an AL plate, soft acrylic, PVC transparent plate, copper plate, or OHP film, more Specifically, it may be an OHP film. In the present invention, since the film constitutes a frame for stably curing the resin, the material is important. If the adhesive force between the film and the resin is too large, a problem occurs that the surface of the resin is damaged in the step of removing the film from the cured resin. Can be. In addition, it should have the appropriate strength and flexibility to form a space suitable for the surface and groove of the curved ceramic.

The third step is a step of adding a resin to the space between the groove or the surface of the ceramics, the frame consisting of a film. To add the resin in liquid form, a cup, a paper cup, an eye dropper, a syringe, a rubber hose, or the like may be used. More specifically, a control mechanism such as a syringe may be used to suppress bubble generation and minimize damage to resin properties. In addition, in order to further minimize the generation of bubbles may be added in a state in which the resin in close contact with the film configured in the second step.

The resin may be mixed with a curing agent for stable curing, and may be liquid. The weight ratio of the resin main material and the curing agent may be in a ratio of 1 to 3: 1, 1.5 to 2.5: 1, 1.8 to 2.2: 1 or 2: 1, but is not limited thereto. If the ratio of the resin and the curing agent is different from this, problems may occur such that the curing is not easily achieved or the color development of the resin is not appropriate.

Prior to adding the resin, the third step may further include removing bubbles in the resin by using a degassing machine in the resin mixed with the main material and the curing agent.

The fourth step is to cure the resin of the liquid phase added in the third step. Such curing may be for 25 to 35 hours, 28 to 32 hours, 29 to 31 hours or 30 hours. If the curing time is too short, the resin may not be cured sufficiently and the shape of the resin may be damaged when the film is removed. If the curing time is longer than this, the resin is hardened to bond more strongly with the film, thereby making it impossible to remove the film mold. There may also be a problem that the productivity is lowered.

The fourth step may further include removing the film mold after curing of the resin, polishing the cured resin, or applying a varnish to the surface of the resin.

Another aspect of the present application provides a ceramics produced by the above manufacturing method. Such porcelain may be an additional resin to the side, side and bottom, side and top, or side, top and bottom of the porcelain.

The ceramics are as described above.

The resin added to the ceramics may be mixed with the main material and the hardener, and the weight ratio of the resin main material and the hardener may be in a ratio of 1 to 3: 1, 1.5 to 2.5: 1, 1.8 to 2.2: 1 or 2: 1. However, the present invention is not limited thereto. In addition, the resin may be transparent or have a unique color or gloss.

According to the present invention, it is possible to stably and precisely add a resin, which is a material that is difficult to combine with a ceramic product, and as a result, it is possible to efficiently manufacture a ceramic product having an aesthetic and originality.

Hereinafter, the configuration and effects of the present invention through the embodiments will be described in more detail. These examples are only for illustrating the present invention, but the scope of the present invention is not limited by these examples.

Example 1: Mold Making

The purpose of this study was to produce a gypsum mold that can hold a ceramic-shaped mold to efficiently manufacture ceramics of a certain shape. The gypsum mold may be manufactured differently according to the shape of the target ceramics, and in the present embodiment, the shape of the cup is selected by way of example.

First, a prototype for a plaster mold was produced, and when the prototype was produced, the hollow was made by hollowing and carving the soil mass (FIG. 1 and FIG. 2), and the soil mass was changed into a plaster mass through a mold. As a step of smoothing the gypsum mass, the rough portion of the gypsum circular surface was polished with sandpaper to make it smooth.

A plaster mold was manufactured as shown in FIGS. 3 and 4 based on the polished plaster prototype, and the mold was dried by drying at a temperature of 55 ° C. for 30 hours.

Example 2 Manufacture of Porcelain Prototypes Using a Mold

Soil water (slip) was added to the mold prepared in Example 1 to be a porcelain-shaped material. In the present embodiment, a white porcelain slip having high light transmittance is prepared as an example.

In Example 1, the prepared soil water (slip) was injected into the dried plaster mold (FIGS. 5 and 6). Slips which occurred in the mold after 12-15 minutes after injection were removed (FIG. 7). After confirming that the soil attached to the mold wall is dried, it was removed from the mold (Fig. 8).

The stripped porcelain prototype was dried for about 7 to 10 days in the shade without direct sunlight. This prevents the warping of the ceramics during the initial and chaebol process in the kiln in high temperature conditions. The dried porcelain was primed in a kiln at 850 ° C. temperature. The primed porcelain surface was polished more smoothly with sandpaper and washed with water (salt oil) and dried again for 24 hours (FIG. 9).

Glaze used transparent oil because the color of the soil itself, that is, the earth was white. Glaze was applied to the porcelain, which was then placed in a kiln, and conglomerated at 1250 ° C.

Example 3: Resin Flakes on or Under the Ceramic Surface

On the surface of the conglomerate ceramics, a film was used to form a frame to hold the shape of the resin. After selecting the color of the resin to be added to the ceramic, the resin base and the curing agent were combined in a weight ratio of 2: 1. When the mixing ratio of the resin and the curing agent is different, problems such as inability to easily cure or inadequate color development of the resin may occur. In addition, since bubbles are very easily generated in the process of adding the resin, which may lead to deterioration of the quality of the ceramic product, bubbles in the resin are removed using a degassing machine.

Resin was added slowly so that the prepared liquid resin could be in close contact with the film wall formed on the ceramic surface (FIG. 10). If the resin is added at a high rate, bubbles may occur or the properties of the resin may become unstable.

After fixing for 30 hours to allow the resin to be cured sufficiently, the film molds were removed from the ceramics. When the curing time of the resin is significantly shorter than that, the resin in the liquid form is not sufficiently cured, resulting in a problem that the surface of the resin is damaged during the removal of the film mold.

The resin part was polished with sandpaper to correct the shape of the cured resin. Finally, a phototechnical agent was applied to the polished resin part to complete a ceramic product in which the resin was designed (FIG. 11).

Therefore, although the prior art level has a technical difficulty in shaping the resin into a stable and accurate shape on the surface or side of the ceramic product, if the ceramic product is manufactured as in the process of Examples 1 to 3 of the present invention, It was confirmed that resin, which is a difficult combination, can be added stably and precisely, and that a ceramic product with an aesthetic and originality can be effectively manufactured.

From the above description, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features. In this regard, the embodiments described above are to be understood in all respects as illustrative and not restrictive. The scope of the present invention should be construed that all changes or modifications derived from the meaning and scope of the following claims and equivalent concepts rather than the detailed description are included in the scope of the present invention.
