The tile raw material composition is put into an injection molding machine, And a step of performing a firing process at a temperature of 860 [deg.] C. Thus, the present invention can be provided as a functional tile having desired properties.

In particular, we have used pozzolan ores containing germanium (Ge) as gemstones from Pozzolan mine in Shinan County, Chonnam Province and tried to provide nature-friendly tiles for building materials using only natural-friendly raw materials from natural sources.

The process of manufacturing a functional tile for building materials using the pozzolan calculated from the mine at the coast of Jinda Island, Jeongju Island, and Yongyu Island is shown in Fig.

As shown in FIG. 1, the pozzolan raw materials used in the tile composition of the present invention all use natural raw materials. First, the pozzolan produced in the pozzolan mine in Shinan District, The pozzolan ore having a size of 1 to 20 mm is put into a firing furnace and fired in the range of about 300 ± 50 ° C. for 4 to 6 hours to perform the process of removing impurities, The kaolin processed by the same method as 4 ㎏ of pozzolan obtained by pulverizing minerals in the range of 200 ± 50 mesh was added 2.5 ㎏ in order to improve the bonding force and durability as a tile, and also the microporous property was secured in the tile product, 1.5 kg of fly ash sifted with a size of 250 ± 50 mesh and a means to increase the antibacterial activity of the tile product 0.5 kg of the calcined shell powder was mixed with 1.5 kg of a solution type sodium silicate having a molar ratio of SiO ₂ / Na ₂ O of 2.10 to 3.30 as a binder for increasing the binding force of the raw material to form 10 kg 100% composition, the tile raw material composition is put into an injection molding machine, molded into a tile product of a desired size, dried, and then sintered at a temperature of 830 to 860 ° C. Technological thought can be implemented.

The inventors of the present invention prepared a raw material by the above method, prepared a tile sample product at a composition ratio shown in Table 2, and performed a compressive strength test according to KSF 4724, and obtained the results shown in Table 2 below.

As can be seen from the data in Table 2 above, when the pozzolan raw material powder is out of the maximum value in the range of 40 ± 17 weight of the tile composition, the compressive strength is remarkably lowered. Therefore, in the present invention, It is possible to secure a compressive strength of 4000 N / m < 2 > or more as desired by the inventors when the composition is blended in the range of 40 ± 17% by weight, 25 ± 10% by weight of kaolin, 15 ± 5% by weight of fly ash and 5 ± 2% by weight of calcined shell powder Respectively.

Drying conditions in the above manufacturing process are preferably dried in a shady place at room temperature because cracking occurs when it is dried in hot heat or sunlight, but it takes 2 to 3 days to dry at room temperature (25 to 30 ° C) Therefore, the process is applied to the step of drying at 60 ± 5 ° C for 24 hours, and the process is applied to the firing step.

In the tile manufacturing process of the present invention, the firing process is applied to a maximum firing temperature of 840 ± 10 ° C with a maximum firing time of 2 to 3 minutes and a total firing time of less than 30 minutes in the firing furnace.
