Description

Volcanic rock tile and its manufacturing method {TILE COMPRISING VOLCANIC ROCKS AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a tile produced using volcanic rock powder obtained from volcanic rock.

Generally, tiles are flat clay plastic products made to cover the surface of floors, walls, etc., and are made of interior tiles, exterior tiles, mosaic tiles, acid resistant tiles, floor tiles, and salt salts. Tiles and query tiles. Tiles are easy to install, hardly crack or discolor after construction and are durable. They are used in kitchens, restrooms, bathrooms and washrooms.

The tile manufacturing technology has been developed in various forms, and calcined tiles having anion generation, water resistance, and the like are provided by mixing functional minerals with basic tile bases. In the case of non-fired tiles, functional minerals are produced using water glass or low alkali cement as a binder.

Additives for imparting functionality as described above consists of a large number of synthetic chemicals. For example, most of the minerals used for the purpose of generating negative ions have a problem in that high radioactivity is detected, and thus they cannot satisfy the conditions of stability and eco-friendliness at the same time.

Furthermore, synthetic chemicals may have to be prepared separately through several stages of the process.

One object of the present invention is to provide a tile using a natural material different from the conventional method and a method of manufacturing the same.

Another object of the present invention is to provide a tile having a natural material with improved stability to the human body while having at least one function.

Another object of the present invention is to recycle waste resources in the manufacture of tiles to prevent waste of resources required to manufacture other synthetic materials, and to reduce manufacturing costs.

One embodiment of the present invention and the volcanic rock tile includes a tile body and a glaze layer for realizing the above object. The tile body includes clay and is first fired to have a certain shape. The glaze layer is applied to the first fired body, which is fired secondly. The glaze layer contains volcanic rock with a particle size of 10 to 75 microns.

According to an aspect of the present invention, the tile holder comprises 1 to 10% by weight of volcanic rock.

According to another aspect of the invention, the volcanic rock occupies 5 to 20% by weight of the glaze layer. The glaze layer is 15 to 20% by weight of feldspar, 15 to 20% by weight of limestone, 20 to 25% by weight of silica, 5 to 10% by weight of alumina, 10 to 15% by weight of kaolin, and 5 to 10% by weight of frit. It may further include.

According to another aspect of the present invention, the volcanic rock includes scoria or basalt produced in Jeju.

Volcanic rock production method according to another embodiment of the present invention comprises the steps of (a) preparing the first baked fired tiles containing clay, (b) grinding the volcanic rock to have a particle size of 10 to 75 microns, ( c) mixing the pulverized volcanic rock and other materials with water to produce a glaze layer, and (d) secondary glazing at a higher temperature than the first firing by lubricating the glaze layer on the tile substrate. Steps.

According to one embodiment of the present invention, the other material of step (c) includes feldspar, limestone, silica, alumina, kaolin, frit.

Tiles according to the present invention configured as described above have a photocatalytic effect due to the inclusion of titanium dioxide as well as antibacterial, heavy metal adsorption, volatile organics removal, far-infrared radiation function unique to volcanic rock. Because of this, when manufactured from interior tiles can improve the new house syndrome, it is possible to increase the effect that the residential space that is continuously tiled contributes to health promotion.

In addition, according to the difference in the content of the volcanic rock and the difference in the processing temperature, the color is produced differently can cause an aesthetic sense for the indoor environment.

Hereinafter, a tile according to a preferred embodiment of the present invention and a manufacturing method thereof will be described in detail with reference to the accompanying drawings.

Volcanic rocks (volcanic rocks) are magnified rocks where magma rises to the shallow surface of the surface or underground. Because magma cools and solidifies quickly on the surface or in shallow ground, most volcanic rocks are crystalline or glassy with very small particles.

 Volcanic rock that can be collected in Jeju is a safe substance with no radioactivity and is composed of olivine, fluorite, plagioclase and magnetite. The color is mainly reddish brown, yellowish brown, green, and dark gray.

Among the volcanic rocks, scoria is a volcanic rock that is oxidized by combining with oxygen in the air as the magma erupts 1600 degrees above ground.

Table 1 shows the composition ratios analyzed by the Korea Chemical Testing Institute (ICP Analysis) and Japan Food Analysis Center (XRF Analysis).

The clusters have a specific gravity of about 0.9 to 1.7 due to porosity, and as shown in Table 1, the basic content of silicon dioxide, aluminum oxide, and iron dioxide has a stable structure of 77.42 wt%. The titanium dioxide component was analyzed at 2.54 wt%, but generally contained in the range of 2-7 wt%.

The cluster has a high absorption rate of 20% or more due to its porosity, and its specific surface area is suitable for adsorbents that can quickly suck contaminants. Adsorbed pollutants are characterized by titanium dioxide, which is photocatalyst (photocatalyst) action (titanium oxide oxidatively decomposes harmful substances). This circulation of adsorption and decomposition has a permanent persistence, which is a feature that contrasts with other minerals.

The basalt chemistry of magma formed as it cools on the surface is similar to that of clusters, but has a specific gravity of 2.78, which is somewhat poor in porosity. However, when used as a powder, it is a species of Jeju volcanic rock that has functions such as antibacterial activity.

Both clusters and basalt are minerals produced by volcanic activity, and they can be mixed with tiles and commonly have effects such as far infrared radiation, heavy metal adsorption, antibacterial, volatile removal, and deodorization. Since Jeju volcanic rock has a weak alkalinity, it is possible to improve the preservation and function by adjusting the pH (ph) such as clay used as tile material to neutral and weak alkaline.

In addition, clusters are mainly reddish brown, but basalts tend to be relatively dense and dark gray. Using these color differences, one can select one or mix them suitably as needed to produce tiles of the desired color or density.

1 is a flowchart illustrating a manufacturing process of a volcanic rock tile according to an embodiment of the present invention.

As illustrated in the figure, the volcanic rock to be mixed with materials (material and / or glaze) for producing the tile should be processed (S10). Volcanic rock can be collected in Ongpo, Hallim-eup, Bukjeju-gun, Jeju Island, and can also use chopped sludge from stone factories. The collected volcanic rock is crushed to the required level through the grinding process.

The crushed volcanic rock may be added to the tile body, it may be used only in the glaze (S20). When the volcanic rock is added to the tile body (S30), the tile body may include 1 to 10% by weight of crushed volcanic rock based on clay.

Volcanic rocks are added or not added to the tile is first fired at 1000 ~ 1060 ℃ (S40). By the primary firing, the tile body maintains a constant shape such as a plate shape.

Whether to apply the glaze to the first calcined tile should be determined (S50). If volcanic rock has already been added to the substrate before the first firing, useful functions by volcanic rock can be exerted without glazing.

If you want to form a glaze layer by applying a glaze (S60), the manufacture of the glaze should be preceded.

Glazes contain crushed volcanic rock at levels ranging from 5 to 20% by weight, based on their weight. In this case, the pulverized volcanic rock preferably has a grain size (grain size / granularity) of about 10 to 75 microns. If the particle size is too small, the cost of grinding is increased. If the particle size is too large, the volcanic rock is not dispersed to an appropriate level such as sedimentation and failure of the body and bonding.

The glaze layer formed tile body is secondarily fired at a temperature of 1050 ~ 1200 ℃ (S70).

In the above, the volcanic rock zeolite (synthetic zeolite using a cluster is disclosed in Korean Patent No. 301790, in which the applicant participates as a co-inventor) may be added without directly adding volcanic rock.

By the above process, a tile containing volcanic rock is produced in a certain form of tile.

Table 2 is a test report of the Industrial Environment Research Center (KATR, 232-22, Yongdu-dong, Dongdaemun-gu, Seoul) for the volcanic rock tile containing pine according to an embodiment of the present invention. According to this report, the above volcanic rock tile has a far infrared ray emission rate of 0.923 and a radiant energy of 3.72 * 10 ^ 2.

Table 3 is also the test result of the Industrial Environment Research Center for the tile, referring to this table, it can be seen that the antimicrobial activity of E. coli, Pseudomonas aeruginosa, etc. of the tile is 99.9%.

Table 4 is also the test result of the Industrial Environment Research Center for the tile, the result of the test using the formaldehyde gas on the tile.

As can be seen from the table, formaldehyde is deodorized by about 90% by the tile. This makes it possible to effectively remove formaldehyde (and volatile organic compounds), which is the cause of recent sick house syndrome, to provide a clear and comfortable living environment.

The tile also has the ability to control the moisture in the room. This functionality does not disappear in a short period of time, and is continuously maintained based on structural features such as volcanic rock's porosity, so that it is possible to enjoy semi-permanent functional effects with one tile construction.

Although the above has been described with reference to the accompanying drawings and volcanic rock tile according to the present invention, the present invention is not limited by the embodiments and drawings disclosed herein, but within the scope of the technical idea of the present invention Various modifications can be made by those skilled in the art.
