Description

Ceramic decorative tiles with carving parts and its manufacturing method

The present invention relates to a ceramic decorative tile having an openwork portion and a method for manufacturing the same, and more particularly, a space portion is formed inside the tile and a pattern directing portion is formed on the surface to produce a three-dimensional pattern by opening various shapes and patterns. It relates to a ceramic decorative tile having a hollow part and a manufacturing method therefor.

In general, in order to satisfy the needs of modern people who pursue diversity, various building materials for interior decoration are used to add functionality and beauty, while building materials are advancing day by day.

Among the building materials used for such construction, there is a tile for attaching to a wall to enhance the effect of interior and exterior decoration and waterproofing and heat resistance of the building.

Among these tiles, interior wall tiles are made by finely pulverizing inorganic raw materials such as kaolin, clay, ceramics, pyrophyllite, limestone, etc. in a ball mill, manufacturing them into powder in a spray dryer, and then forming the shape through a molding machine. The product is completed as an interior material through the process of primary firing at 1,100-1,400°C, applying a print glaze of about 0.3-0.5 mm on it, and secondary firing at 1,020-1,050°C.

Since these conventional tiles are composed of a thin single plate, they are formed by applying a glaze on the surface to block the pores, so they do not have the ability to absorb indoor moisture and control humidity, and they are simple without far-infrared radiation, deodorizing effect and antibacterial effect. It has a wall finishing function and was used as a building material rather than a decorative material because it could not produce a three-dimensional pattern.

On the other hand, loess, which has recently been spotlighted as a functional building material, is a nature-friendly material with excellent thermal insulation, insect repellent and antibacterial effects as well as far-infrared radiation and humidity control effects beneficial to the human body. It is manufactured and used in various forms such as wall materials such as bricks and panels, and ceiling materials.

However, the conventional building materials for interior decoration using loess have a problem in that the moisture absorption effect and air circulation effect of loess are insignificant because the loess is thinly applied to the surface of the existing panel or tile-type decorative material.

Therefore, there is loess brick among the building materials for interior decoration using loess, but it is produced through the process of putting loess into a mold and compression molding of loess at a high pressure of 100 tons or more using compression equipment. It had no function as a decorative material.

Figure 4 is a view showing an embodiment in which various shapes of the present invention are produced.
5 is an exemplary view of the rear configuration of the present invention.

The configuration of the present invention will be described in detail with reference to the accompanying drawings as follows.

First, the implementation state for each process for forming the ceramic decorative tile having the openwork part of the present invention will be described as follows.

1st process material powder processing process

Substrates (white porcelain, buncheong, sancheong, kaolin, clay, loess, elvan) are collected and each of them is pulverized with a ball mill to obtain a fine powder.

Here, when the grinding means is not provided, a fine powder is obtained by collecting the kaolin, clay, or loess soil and immersing it in water, and the elvan stone powder can be purchased and used.

In some cases, only kaolin and clay or loess may be used.

2nd process powder material mixing process

The powder obtained in the above raw material powder processing process is mixed with 70 parts by weight of kaolin, 10 parts by weight of clay, 10 parts by weight of loess, and 10 parts by weight of elvan stone powder and mixed in a spray dryer.

Here, a lot of kaolin is used to maintain hardness when baked and fired, and mixing ocher or clay is to expect far-infrared emission while having pores. is the purpose

3rd process material kneading process

The mixed powder material obtained in the powder material mixing process is kneaded so that the moisture content is 20-30%.

At this time, the moisture content may be slightly changed, but when the moisture content is less than 20%, the dough becomes too high, and when it exceeds 30%, the dough becomes too soft and there is a risk of deformation after molding.

Step 4 Extrusion molding process

The material kneaded in the kneading process is extruded in a high-pressure extruder of at least 10 tons or more so that the wall adhesion part 11, the inner space 12, the surface part 13, and the open part 15 are integrally formed in the extruder.

At this time, the extruder will be configured in various ways according to its power, so the power of the extruder will be acceptable as long as the dough pushes out the mold and forms the tile molded product.

Here, depending on the purpose, the wall adhesion portion 11 and the surface portion 13 may be integrally formed.

5th process division process

The tile molded article continuously and repeatedly molded in the extruder is cut and divided to the desired length.

At this time, it is most ideal to cut with a wire when cutting a tile molded product that is continuously and repeatedly formed.

Step 6 Working Frame Combination Process

The working frame is coupled between the surface part 13 and the open part 15 of the tile molded product divided in the division process to prevent deformation.

The working frame used at this time is disassembled and prefabricated to cover the surface part 13 of the tile molded product and support the open part 15 to prevent external force from being applied to the surface part 13 of the tile, and to prevent the open part 15 from sagging. This is to provide convenience to the openwork work by preventing it from happening.

7th step openwork process

In the work frame coupling process, the work frame is coupled to prevent deformation of the tile molded product, and the shape of the operation unit 15 is deformed into various desired shapes or carved with an openwork knife to form an embossed or engraved pattern.

At this time, in order to maintain an appropriate degree of deformation, moisture must be supplied by spraying, etc., and various shapes are produced by deforming the shape of the operation part, or the method of directing patterns and shapes with openwork is carried out separately or simultaneously.

In addition, the attachment hole 16 is formed together in the wall adhesion part 11 so as to be advantageous for hanging on the wall or ceiling surface.

Re-eight process drying process

Dry the tile molded product on which the engraving is completed in the engraving process so that the moisture content is less than 5%,

At this time, there are two types of drying method: natural drying and forced drying. Natural drying requires drying at room temperature for 2-3 days, and forced drying is advantageously performed inside a drying furnace at about 60°C to 70°C.

If drying in a furnace with too high a temperature for early drying, there is a risk of cracks on the surface, so a lot of care is required for drying.

9th process work frame separation process

The working frame is separated from the tile molded product dried in the drying process.

10th process 1st firing process

The tile molded article dried in the drying process is baked in a kiln at about 900°C to 1,000°C and fired into tiles.

Step 11 Partial glazing process

The glaze is applied only to the hollow part 15 of the tile fired in the first firing process.

At this time, the reason not to apply the glaze to the wall adhesion portion 11 and the surface portion 13 is that the glaze is not applied to the wall adhesion portion 11 and the surface portion 13 because the clay and ocher ceramics mixed with kaolin form Because the pores are not blocked with a glaze, it is intended to absorb moisture as well as to obtain the effects of deodorization and eradication of bacteria due to these pores.

In addition, it is a means to further emphasize the three-dimensionality of the openwork by applying a glaze only to the openwork part 15 to produce various patterns, as well as to produce a different aesthetic sense from the wall adhesion part 11 and the surface part 13 .

12th process Secondary firing process

In the glazing process, the glazed tile only on the open part is baked in a kiln at about 1,100°C to 1,300°C to complete the ceramic decorative tile with the open part,

The present invention completed by carrying out the method for manufacturing a ceramic decorative tile having an openwork portion of the present invention described above is a wall adhesion portion 11, an interior space 12, a surface portion 13 and an openwork portion 15 that are in close contact with the wall surface. ) is integrally formed and the openwork portion 15 is formed in various shapes and patterns to complete the ceramic decorative tile.

Here, the material forming the wall adhesion part 11, the surface part 13, and the hollow part 15 is mixed with 70 parts by weight of kaolin, 10 parts by weight of clay, 10 parts by weight of loess, and 10 parts by weight of elvan powder, The wall adhesion part 11 and the surface part 13 are baked and fired without glazing, and the openwork part 15 is glazed and baked and fired, so that the wall adhesion part 11 and the surface part 13 are porous. and the openwork part 15 is configured to block the pores and only produce patterns.
