More particularly, the present invention relates to a ceramic tile for automobile running test, The present invention also relates to a ceramic tile for automobile running test and a ceramic tile for automobile running test manufactured by the method, which can improve manufacturing efficiency and contribute to cost reduction.

Car driving test is a test that must be performed when obtaining a driver's license. Driving test can be conducted on various roads such as a high-speed main circuit, a straight line, a general-purpose test, a circular low-friction road, and a radio disturbance test road.

In particular, when testing the vehicle, the tile must have a smoothness suitable for sliding tiles (for ice) so that the running test can be performed accordingly.

However, since the tiles of existing driving test sites are made of simple general tiles, it is difficult to maintain the surface smoothness due to roughness of the surface, and the strength and luster are reduced. Therefore, a new concept of ceramic tiles is needed.

1 is a flowchart of a method of manufacturing a ceramic tile for a vehicle running test according to an embodiment of the present invention.

According to the method of manufacturing a ceramic tile for an automobile running test according to an embodiment of the present invention, the surface smoothness can be maintained, and strength and gloss can be improved. In particular, a ceramic tile is manufactured by a simple and efficient method Thereby improving manufacturing efficiency and contributing to cost reduction.

Particularly, the present invention is applied to a ceramic tile for automobile running test manufactured by the manufacturing method in addition to the right of the ceramic tile manufacturing method for automobile running test. At this time, the size, shape, color and the like of the ceramic tile for automobile running test are completely independent and limited to the ceramic tile manufactured by the ceramic tile manufacturing method for automobile running test.

The method of manufacturing a ceramic tile for automobile running test may include a step of preparing a raw material (S10), a glaze manufacturing step (S20), a mold making step (S30), a tile forming step (S40), a tile drying step (S50), a tile firing step (S60) , And a tile cooling step (S70).

The raw material preparing step (S10) is a step of preparing a raw material of the ceramic tile. In this step, 0.3 wt% of the peptizing agent was added to 18 wt% of clay, 32 wt% of fuming stone and 50 wt% of feldspar, and the raw material was mixed at 57 wt%, followed by pulverizing the raw material blended for a predetermined grinding time A specific gravity of 1.6 ± 0.5, a viscosity of 150 ± 100 cp, and a residual ratio of 10 ± 5% by weight.

The glaze manufacturing step (S20) is a step of manufacturing a glaze into a ceramic tile. Glazing can help maintain surface smoothness.

In the glaze manufacturing step S20, 3 weight% of barium carbonate, 10 weight% of zirconium silicate, 3 weight% of magnesium oxide, 15 weight% of calcium carbonate, 15 weight% of frit, 45 weight% of feldspar, 0.5% by weight, and 60% by weight of the resultant. The raw materials blended for a predetermined grinding time were pulverized to obtain a mixture having a specific gravity of 1.6 ± 0.5, a viscosity of 150 ± 100 cp and a retention of 1.0 ± 0.5% The condition can be met.

Meanwhile, the raw material preparing step (S10) and the glaze manufacturing step (S20) may be performed in parallel. That is, any step may be performed first in the raw material preparing step (S10) and in the glaze manufacturing step (S20).

The raw material and the glaze can be passed through the raw material drying step (S11) and the glaze drying step (S21), respectively. After the raw material preparing step (S10) and the glaze manufacturing step (S20) S11, and S21), the quality of the raw material and the glaze can be improved.

In the case of drying, the moisture content is 7.5 ± 0.5 wt%, the drying amount is 3.5 ton / hr, and in the case of glaze, the drying moisture is 6.0 ± 0.5 wt% and the drying amount is 3.0 ton / hr.

The mold making step S30 is a step of manufacturing a mold for manufacturing the ceramic tile.

At this time, the mold may be a mold of a depressed shape of the upper mold product, and a depressed mold may be formed at the edge portion of the mold upper mold. By doing so, the smoothness of the glaze surface can be improved.

The mold may be manufactured in a round-shaped embossed shape having a mold shrinkage rate of 8.0 wt%, a concave depth of 1.5 mm, and a length of 2.3 mm.

The tile molding step S40 is a step of molding the ceramic tile through the mold. In this case, the raw material can be filled first and then the secondarily filled with glaze.

When the raw material is first filled, the raw material made by the above-described process is charged into the mold and filled. When filling the glaze in the second place, the glaze can be filled by side charging on the filled primary raw material, and the thickness of the glaze can be 2.0 mm.

Once the glaze is filled in the second place, these materials can be pressure molded under the condition of 150 ± 50 kg / cm 2.

The tile drying step (S50) is a step of drying the molded product. That is, when the molding is completed through the tile molding step (S40), the semi-finished product is taken out from the air wire, and then dried in a dryer.

The tile firing step (S60) is a step of performing plastic working on the dried product.

In this process, the dried semi-finished product is placed on the fireproof plate, and then the fireproof plate and the product are placed in the firing kiln, and the firing temperature of the kiln is set to 1220 to 1260 ° C for 300 to 400 minutes.

The tile cooling step (S70) allows the finished product to be manufactured by taking out the fired product and then cooling it.

According to this embodiment having the structure and function as described above, the surface smoothness can be maintained, and the strength and gloss can be improved. In particular, the ceramic tile can be manufactured by a simple and efficient method, Thereby contributing to savings.

The effect of the present invention will be further elaborated.

For the reference, when dry glaze molding is made with a general mold, edges of the product may be sharp due to the surface tension of the glaze, but this can be solved by round double treatment of the mold.

Although the smoothness of the glaze due to the surface tension of the glaze may be caused by the edge rupture, it can be solved by round double treatment of the mold.

Smoothness suitable for sliding test tiles (for ice sheets) due to the smoothness of a certain surface can be realized.

Particularly, the thickness of the product reaches 30 mm and the strength and gloss are increased due to stabilization of vitrification of the glaze and substrate due to a sufficient firing time (300 minutes or longer of the transfer time).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or alterations are intended to fall within the scope of the appended claims.
