Description

Manufacturing method of glaze for majolica technique and manufacturing method of painting tile

The present invention relates to a manufacturing method of glaze for the Majolica technique, and more particularly, to a method of manufacturing a glaze that can be prevented from being mixed with the glaze painted on the plate.

In general, tiles are made of porcelain or ceramics as a raw material, and the manufacturing process thereof is as follows. First, clay, which is the basic material (tato), is mixed with water to form a dough state, and the air inside is sufficiently removed, and then plated and molded to have an appropriate size and shape. Then, it is dried at low temperature until moisture except crystal water is removed, and the dried plate-shaped molding is first calcined and cooled at a temperature of about 900 ° C. Then, glaze is applied to the surface of the molded product, and then dried, and then calcined at a temperature of about 1300 ° C. to complete the tile production.

Picture tiles, that is, tiles having patterns, such as murals, require additional processing compared to conventional tiles. First, a sketch is drawn using a combustible material on the surface of the plate-like tile subjected to the primary firing. Then, based on the sketch, draw a picture using a glaze mixed with pigments represented in different colors after firing, and then fire by coating a glaze that ensures transparency after firing. In this case, in the process of applying the glaze mixed with the pigments, inevitably, each of the pigments having two or more colors must be used together with the glaze to draw a picture on the surface of the primary fired article one by one. Pigments and glazes used are used in an aqueous state.

Therefore, when paintings having different colors in one tile are drawn, the glazes containing the pigment component in the aqueous state are mixed with each other, and the color is mixed at the portion where two or more different glazes are in contact with each other. Later, there was a problem that the painting such as the mural to be expressed on the surface of the tile is not clearly expressed.

In order to solve this problem, the present inventor has proposed and registered the patent No. 0382572. Patent No. 0382572 relates to a method of manufacturing a mural tile in which various patterns are formed, and color mixing does not occur at the interface between the first and second paint layers, which are painted by the sketch, and the first paint layer is formed. After forming a second coating layer without undergoing sufficient drying process, it is possible to shorten the time of the manufacturing process.

To this end, Patent No. 0382572 discloses that the water repellent added to the glaze used for the sketch is a silicone-based water repellent, the component ratio of which is 7 parts by weight to 12 parts by weight and 10 parts by weight to 15 parts by weight of the pigment component based on 100 parts by weight of the water repellent. After the sketch is drawn using the glaze consisting of parts, it is composed of the glaze with the color of the water-based glaze component on the boundary drawn by the sketch.

According to the patent No. 0382572, the interface becomes clear so that the painter can accurately express the desired painting, and immediately after completion of the sketch, the work of the first and second paint layers can be carried out without drying. Therefore, not only the mural can be drawn on the surface of the tile in a short time, but also there is no mixing of pigment components of different colors at the border of the finished tile, thereby reducing the defects.

The above-described patent 0382572 makes it possible to prevent the phenomenon of overlapping the conventional glaze, but the present inventors have led to the present invention as a result of repeatedly research to derive a solution different from that of the patent 0382572.

An object of the present invention is to provide a glaze manufacturing method for majolica technique that can be prevented from mixing the glaze.

Another object of the present invention is to provide a manufacturing method of a painting tile using glaze for majolica technique.

The object of the present invention described above, in the method for producing the glaze used in the majolica technique, the step of mixing the frit powder, the step of mixing and then mixing the pigment in the mixed frit powder, and adding a binder and a water repellent It can be achieved by providing a glazing method for the majolica technique comprising the step of mixing.

According to a preferred feature of the present invention, in the step of mixing the frit powder, 50 parts by weight of feldspar, 15 parts by weight of quartz, 20 parts by weight of kaolin, 13 parts by weight of limestone and 2 parts by weight of galvanization can be mixed with respect to 100 parts by weight of frit. have.

According to another preferred feature of the invention, the pigment may be composed of an oxide consisting of zinc, titanium, iron, copper and chromium, sulfides and chromates.

2 and 3 is a flow chart of the manufacturing method of the painting tile using the glaze for majolica technique according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the embodiments described below are only for explanation of the embodiments of the present invention so that those skilled in the art can easily carry out the invention, It does not mean anything. In describing various embodiments of the present invention, the same reference numerals are used for components having the same technical characteristics.

First, before describing an embodiment of the present invention, the majolica technique will be briefly described. Majolica refers to Italian pottery. Products made with the Majolica technique are mainly painted with colors such as blue, purple, yellow, green and red on the white background of petroleum. This majolica technique has been introduced throughout Europe since the 16th century, and in France, this kind of pottery was called faience under the name of Faenza, which became the name of the European majolica pottery.

The present invention relates to a method of making a glaze for use in this majolica technique. As shown in FIG. 1, the method for preparing glaze for majolica technique according to an embodiment of the present invention includes the steps of mixing the frit powder (S501), mixing the pigment with the mixed frit powder, and then stirring (S502); , Adding and mixing the binder and the water repellent (S503).

Here, frit powder generally refers to a glassy powder. In the case of mixing such frit powder, 50 parts by weight of feldspar, 15 parts by weight of quartz, 20 parts by weight of kaolin, 13 parts by weight of limestone, and 2 parts by weight of zincated can be mixed with 100 parts by weight of frit. The reason for mixing the frit powder in such a ratio is to make the surface of the glaze and the glaze overlapping, and to make up the surface of the glaze or the glaze dropping as possible to complement the phenomenon.

In addition, the pigment additionally mixed with the mixed frit powder may be configured to exhibit color to the glaze and may be white or colored. In this case, as the pigment, an inorganic pigment consisting of an oxide composed of zinc, titanium, iron, copper and chromium, a sulfide and a chromate can be applied. These pigments are mixed with the frit powder and then agitated so that the glaze to be produced thereafter is colored in its entirety.

In addition, the binder helps the mixing of the frit powder and pigment, prevents deformation during the oilification of the glaze, and prevents damage such as falling off of the glaze component after coloring, for example, a polyester-based binder Can be applied. The water repellent may be applied to silicone EN-based silicone oil, and the water repellent serves to prevent mixing (marbling) during coloring between the glaze and the glaze mixed with the binder.

A process of manufacturing a picture tile using the glaze manufactured by the glazing method for the majolica technique according to the embodiment of the present invention as described above will be described with reference to FIGS. 2 and 3.

First, as shown in Figure 2, the manufacturing method of the painting tile according to an embodiment of the present invention is to mix the base material and make a predetermined size to make a magnetic plate (S100), and to naturally dry the divided plate Step (S200), putting the dried plate in a kiln, the first step of firing at 800 ~ 900 ℃ (S300), the step of drawing the sketch after spreading the fired plate (S400) and firing glaze for majolica technique Coloring the plated (S500), coating the coating using a ceramic powder on the glaze-painted plate and drying (S600), and after coating the ceramic powder dried plated into a kiln at 800 ~ 900 ℃ Secondary firing step (S700), which will be described in detail for each process.

Referring to FIG. 2, in order to manufacture a painting tile, the base material (tato) for making a magnetic plate is mixed and divided into a predetermined size (S100). In this case, in consideration of the shrinkage of the clay, the materials are mixed to make a base material, and then processed and divided to a required size to make a magnetic plate.

Then, the magnetic plate is dried naturally (S200). In this case, the divided magnetic platen is transferred to a drying stand to be naturally dried to remove moisture, and then dried until a predetermined moisture is removed. At this time, the plate is dried for 15 to 20 days in the shade of the humidity is not high so that the moisture content is 3% or less.

Then, put the dried plate in the kiln and the primary firing at a temperature condition of 800 ~ 900 ℃ (S300).

When the primary firing is completed, the fired plate is laid out and then a sketch is drawn according to the drawing (S400). In this case, the pigment for sketches can be variously applied. For example, if a sketch is to be expressed, a sketch may appear even after firing, and a material that burns and disappears upon firing may be used when a natural buried effect is desired.

When the sketching operation is completed, the glaze for the majolica technique prepared by the manufacturing method according to the embodiment of the present invention is colored (S500). The glaze for the Majolica technique according to the embodiment of the present invention has an advantage in that an expression technique of an oil painting or a point drawing format that cannot be expressed by the conventional glaze is possible. Although the property of the existing glaze is close to the water-based mixture of water, the glazing for the Majolica technique according to the embodiment of the present invention has an oily property because it uses a mixture of oil and has properties similar to the feeling of emulsion.

The coloring of the glaze for the Majolica technique may include forming a primary colored layer and forming a secondary colored layer, and may further include forming a tertiary colored layer as necessary. have. Here, the primary colored layer is formed by applying a glaze on the portion where the sketch is not drawn on the plate, the secondary colored layer is formed by applying the glaze on the primary colored layer and the sketch, and the tertiary colored layer is It can be formed by applying a glaze on a secondary colored layer. A detailed description thereof will be given later.

When the coloring of the glaze for the Majolica technique is completed, after coating using a ceramic powder on the colored plate, the plate is naturally dried (S600). The reason for the ceramic powder coating is to enhance the adhesion and durability of the surface, and to facilitate post-production management.

Then, the dried plate is put in a kiln and the primary baking is carried out at a temperature condition of 800 ~ 900 ℃ (S700), the manufacturing of the painting tile is completed.

Referring to Figure 3, it will be described in detail with respect to the manufacturing method of the painting tile according to an embodiment of the present invention.

As shown in FIG. 3, after the sketch 20 is drawn on the magnetic plate 10, the glaze for the Majolica technique is applied to form the primary colored layer 30. In this case, the glaze is applied to the portion where the sketch 20 is not drawn on the plate 10, and if necessary, the same color glaze is used in different areas based on the sketch 20, or the glaze of different colors is used. Can be used.

Then, the secondary colored layer 40 is formed on the primary colored layer 30 and the sketch. In this case, the secondary colored layer 40 may be applied to the primary colored layer 30 and the sketch 20 as a glaze having a single color as a whole, but may be applied in various colors. At this time, according to the characteristics of the glazing for the majolica technique according to an embodiment of the present invention, by applying a glaze having one color to a certain portion to form a secondary colored layer 40, the glaze having a different color in the remaining portion It may be applied subsequently, even if there is no separate partition line, at the interface of the adjacent colored layer does not cause mixing between the glazes and maintains the unique color of each. In addition, when the tertiary coloring layer 50 is to be formed, the glaze may be applied onto the secondary coloring layer 40. Similarly, the tertiary coloring layer 50 may be formed by applying the glaze in various colors. have. Therefore, unlike conventional glazes, it is possible to prevent the mixing between the glazes without a separate partition line, and it is possible to form a picture of a picture tile by a technique similar to an oil painting picture.

For reference, the drying time of each colored layer is different depending on the expression intention of the operator. For example, when a color layer is to be mixed to show a gradation effect, another color layer is formed on the upper portion of the color layer when it is not dry, and when it is to be expressed as an overlapping color, it is dried for a predetermined time and then colored. Drying conditions should be maintained at temperatures above 0 ° C in the absence of sunlight.

When the formation of the tertiary coloring layer 50 is completed, the ceramic powder coating layer 60 is formed by coating with the ceramic powder on the tertiary coloring layer 50.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
