Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile for a float floor,

The present invention relates to a tile for salt floors and a method of manufacturing the same.

Sea salt is a salt that is produced by holding sea water before a salt and evaporating water by applying solar heat and wind. In general, the bottom of the torsion is covered with a floor covering such as a synthetic resin material or a ceramic material tile. When the salt is produced in the salt trough, the salt floor is scratched by using a rubber ladle.

However, rust, insects and foreign matter that are generated in the tidal field or introduced from the outside may be included in the seawater or the sun salt which have been collected for the purpose of the saltation. In such a case, the quality of the sun salt may deteriorate. Therefore, if the bottom of the torsion is contaminated by foreign matter, such foreign matter should be removed quickly. In addition, since solar salt is produced by evaporation of water by solar heat in seawater, it is necessary to increase solar salt productivity by evaporating water quickly.

In addition, tile flooring can be exposed to sunlight, sea water, salt, etc. for a long period of time during the manufacturing process of sun-salt. Therefore, if the resistance to sunlight, seawater, salt, etc. falls, frequent replacement of floor coverings is required. However, the constituents of the bottom finishing material are separated and included in the salt, which may deteriorate the quality of the salt. In addition, when collecting the sun-salt, the floor of the trough is scratched with a rubber ladle. When the floor finish is weak in strength, the components of the floor finish are separated and included in the sun-salt, It can be economical because it has to be given.

Although not shown in FIG. 1, the tile body may include a tile substrate, a first coating layer formed on the top surface of the tile substrate, and a second coating layer formed on the top surface of the first coating layer.

The tile base supports the tile for the tile floor, and it can keep the strength even if it is scratched for a long time with a tool such as a blanket or the like when it is used as a tile for tile floor by including feldspar, kaolin, clay, clay, active and stones. Specifically, the tile base material is composed of 30 to 40% by weight of feldspar based on solid matter, 10-20% by weight of kaolin, 20-30% by weight of clay, 10-20% by weight of clay, 3-5% by weight of talc and 5-10% . Within the above range, it can be used as a tile base of a tile for salt floors, and the strength can be good.

The tile substrate may have a thickness of 7.0 cm to 20 cm, specifically, 7.5 cm to 20 cm. In the above range, it can be used as a base of a tile for salt floors.

The first coating layer is formed on the top surface of the tile substrate to protect the tile substrate from damage by the salt or seawater. It is difficult for the tile for the salt tile floor containing only the tile substrate and the second coating layer to visually confirm that the foreign matter is on the tile or the tile may be damaged by seawater or the like.

The first coating layer comprises a first frit, clay, feldspar or zirconium, and zirconium, thereby protecting the tile substrate by salt when used as a tile for pre-tile floors.

The first frit may be prepared by mixing and melting two or more kinds of glass powders, followed by pulverization. Specifically, the first frit may include 45 to 75.2 wt% of SiO ₂ , 15 to 20 wt% of Al ₂ O ₃ , 0.1 to ₃ wt% of CaO, 0.1 to ₃ wt% of MgO, 3.1 to 5 wt% of Na ₂ O, 0.1 to ₃ % by weight of K ₂ O, 3.1 to 5% by weight of B ₂ O _3, 3.1 to 10% by weight of ZrO _2, 0.1 to ₃ % by weight of ZnO and 0.1 to ₃ % by weight of Fe ₂ O ₃ . Within this range, there may be an effect of protecting the tile substrate and increasing the salt resistance of the tile.

The first coating layer may further comprise a pigment comprising Fe, Cr, and Co. By further containing pigments containing Fe, Cr and Co in the first coating layer, it is possible to reduce the elution of the pigments during long-term use by the tile for pre-salt floors, and the mixing of the first frit, clay, feldspar or silica, and zirconium Can be improved, the gloss of the tile can be increased, and the salt tolerance of the tile can be increased.

The second coating layer is formed on the upper surface of the first coating layer to protect the tile substrate and the first coating layer and to provide gloss, water resistance, and salt resistance to the tile for pre-salt flooring. It is difficult for the tile for salt tile floor containing only the tile base material and the first coating layer to visually confirm foreign matter on the tile or the tile may be damaged by seawater or the like.

Since the second coating layer is formed at the outermost portion of the tile for pre-tile flooring, the surface must be smooth. The second coating layer may have a surface roughness of 0.1 nm to 1000 nm, more specifically 10 nm to 100 nm. In the above range, even if the tiles are left in the seawater for a long time, the foreign objects do not fit well, and scratches may be less likely to occur even when they are pulled by a rubber ladle.

The second coating layer comprises a second frit and kaolin, thereby providing gloss, water resistance, and salt resistance to the tile for pre-salt flooring. A second frit teuneun based on solids 37.86-79.7% by weight of SiO _2, Al ₂ O ₃ 3.1-10.14 wt.%, CaO 10.1-20 wt%, MgO 0.1-3% by weight, Na ₂ O 0.1-3% by weight, K ₂ O 2-5 wt%, B ₂ O ₃ 1.6-5 wt%, PbO 0.1-3 wt%, ZnO 3.1-10 wt%, and BaO 0.1-3 wt%. Within this range, it is possible to provide gloss, water resistance, and salt resistance to the tile for salt floors.

The second coating layer may further comprise a pigment comprising Fe, Cr, and Co. By further containing pigments including Fe, Cr and Co in the first coating layer, the tile for salt tread can be used with little elution of pigment during long-term use, and can be mixed well with the second frit and kaolin, It is possible to increase the gloss of the display device. Since the pigment further contains Mn, the above-mentioned effect can be better. Pigments may use commercially sold products. Specifically, at least one of H-830, H-840, H-850 and H-870 (available from Hanil Pigment Co., Ltd.) can be used as the pigment.

In one embodiment, the second coating layer may comprise 80-94% by weight of second frit on a solids basis, and 6-20% by weight of kaolin. Within this range, it is possible to provide gloss, water resistance, and salt resistance to the tile for salt floors. In another embodiment, the second coating layer may comprise 80-95 wt.% Second frit on solid basis, 1-5 wt.% Kaolin and 1-15 wt.% Pigment. Within this range, it is possible to provide luster, water resistance and salt resistance to the tile for salt floors, and the pigment elution may be small.

The entire first coating layer and the second coating layer may be formed on the tile substrate to increase the gloss of the tile. As a result, it is possible to easily identify the foreign object by the naked eye, to keep the tidal field clean, and to increase the solar reflection and / or radiation to increase the evaporation rate of the water, thereby enhancing the productivity of the solar salt.

The content of the pigment in the first coating layer and the second coating layer may be 0.5 wt% to 10 wt%, more specifically 1 wt% to 6 wt%. Within the above range, tolerance to sunlight, seawater, salt and the like is high for a long period of time, so that the contamination of the sun salt can be prevented.

Since the pigment is included in both the first coating layer and the second coating layer, the pigment can be used as a salt tile by significantly increasing the gloss, and when the foreign matter such as moss is generated, The effect of easy identification can be significant.

The tile for tile floors may have a thickness of 7.5 cm to 20 cm, specifically 7.5 cm to 15 cm. In the above range, it can be used as a tile for salt floors.

This means that the naked eye can not confirm that the tile for salt floor has become dirty. Also, the tile for the salt floor was uneven, which means that the tile was damaged by the salt.
