Luminous tiles and manufacturing method

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a luminous tile and a method of manufacturing the same, and in particular, a luminous tile obtained by applying a glaze including a luminous substance to a general oil- and oil-free tile and firing at a predetermined temperature to obtain a luminous tile for a long time and its manufacture. It is about a method.

In general, modern tiles are beautiful and clean in appearance in modern architecture, and are also attracting attention as excellent building materials due to the strength and wear resistance of the tiles.

However, these beautiful tiles can not see their beauty in the dark, so you must see the structure or appearance only by shining light in a dark place or a dark time.

In addition, when a building or structure, a passage, an emergency exit, etc. are dark, the direction and presence of the building cannot be confirmed, which may cause an accident.

Therefore, in order to prevent such a safety accident, the lights are turned on for each element, and a lot of power was generated because the unnecessary lights are turned on at night for various advertisement lights.

In order to solve the above problems, an object of the present invention is to provide a tile having a luminous property for a long time and a method of manufacturing the same.

The present invention for achieving the above object is a luminous tile coated on a tile coated with a luminous glaze composed of 20-60% by weight of SrAl ₂ O ₃ and 40-80% by weight of frit. It is characterized by.

In order to achieve the above object, the present invention provides a tile, in which a solution mixed with a luminous glaze composed of 20-60% by weight of SrAl ₂ O ₃ and 40-80% by weight frit and water has a thickness of 0.3-1.5 mm. It is applied to the surface of the tile and then fired at a temperature of 600-800 ℃ characterized in that the tile having a luminous property on the surface of the tile.

The present invention for achieving the above object is a tile manufacturing method, 0.3-1.5 mm solution mixed with luminous glaze and water consisting of 20-60% by weight of SrAl ₂ O ₃ and 40-80% by weight frit Applying to the surface of the tile with a thickness of

Drying the tile at room temperature;

It characterized by producing a luminous tile comprising the step of firing the dried tile at a temperature of 600-800 ℃.

According to the present invention, the luminous tile luminous by light has a stray light in a dark place, so that it can be used as a substitute for safety facilities such as decorative tiles, structures, sidewalks, and various simple advertisements even at night. Can be used as a functional building material.

Hereinafter, embodiments of the present invention will be described in detail.

In general, tiles are blended, ground, and dried in a spray dryer to obtain material. Then, the base material is press-molded in a compression molding machine, and then coated with a glaze, etc., and then calcined at a temperature of about 1100-1350 ° C.

The present invention is a mixture of a frit used as a luminous material and a melting agent on the surface of a conventional tile, for example stone or oil-based tiles in an appropriate ratio, and mixed the mixed raw materials with water and applied to the surface of the tile in an appropriate thickness, The luminous tile can be prepared by drying at and then firing at an electric furnace at a temperature of 600-800 ° C.

It can be seen from the following table that the mixing ratio of the frit used as the luminous material and the melting agent in the present invention affects the emission time.

Table 1 is an arbitrary display of each embodiment, and shows the mixing ratio in weight percent based on the total weight of the luminous glaze 100.

Table 2 shows the mixing in the ratio of Table 1 and coated with a thickness of 0.3, 0.5, 0.8, 1, 1.5 mm on the surface of the magnetic tiles. For example, the third group is 30% by weight of luminous material and 70% by weight of frit and then mixed with 100cc of water and applied to the surface of the tile.

Table 3 is a chart showing that the firing temperature and firing time was different for each embodiment.

Specimens prepared by the above method has luminous properties, the effect of which varies depending on the mixing ratio of the luminous material and frit, the thickness and the firing time applied to the tile surface. have.

Table 4 is a chart showing the minimum luminous time according to the type of light used in the luminous experiment.

Table 5 is a chart showing the light emission time according to the mixing ratio of the luminous material and frit, it can be seen that the light emission is maximized in Example 2 and Example 3.

Table 6 shows the light emission photos according to the thickness after application of the mixed solution, and it can be seen that the light emission effect is optimal when the thickness is between 0.8-1.0 mm.

Table 7 is a chart showing the light emission time according to the firing time for each embodiment, when the luminous time is 30 minutes in the second embodiment mixed in the ratio of 40-60% by weight luminous material and 40-60% by frit Examples 2-1 and 2-2 have a light emission time of 20-30 minutes, Examples 2-3 and 2-4 have a light emission time of 30-40 minutes, and Examples 2-5 have a light emission time of 50 minutes. It can be seen that, in Example 2-6, the light emission time is reduced to 30 minutes, which means that the luminous material gradually loses luminous property when the firing time exceeds a threshold.

Putting together Table 5, Table 6, and Table 7, the present invention applies the mixed solution of the calcined porcelain oil-free and oil-free tiles to a thickness of 0.8-1 mm by taking the mixing ratio of Example 2 and Example 3 groups. After the firing was performed at 750 ° C. for 15 minutes in an electric furnace, the experimental data of luminous tiles were found to be optimal.

However, although the firing temperature is the temperature at which the experiment was conducted, the firing temperature may be fluid at about 750 ° C. and at about 15 minutes.

For reference, as can be seen from the diagram, the higher the illuminance, the shorter the photoluminescence time is. In order to find the best specimen according to the mixing ratio, coating thickness and firing time, it was tested under the condition of photoluminescent fluorescent lamp in home, and the test method was 1 meter in the dark after irradiating light for 30 minutes with the specimen under 1.5 meters. The light emission time was measured by observing the specimen with the naked eye.

In addition, the first embodiment group specimen is measured in the photoluminescence time by the specimens of the Examples 2 to 4 groups that are well bonded because the bonding is not performed well in the mixed tile of Table 1 because the conditions are not met.

The following example shows the results of the test according to the type of light and the maximum luminous time according to the luminous time by selecting the best luminous specimen.

Light emission time according to the kind of light Luminous time (minutes) Luminescence time (minutes) sunlight 30 50-60 minutes Fluorescent lamp 30 60 minutes Incandescent light 30 30 minutes Black light 30 120 minutes Headlights of vehicles 30 30

Table 8 and Table 9 show that the higher the light intensity, the shorter the luminous time and the longer the luminous time, and the saturation state is reached when the luminous time exceeds 90 minutes.

After the luminescence is saturated, the brightness gradually decreases after that, and the afterglow remains for up to 4 hours, so the object can be sufficiently checked in the dark.

Tiles according to the invention can be used as swimming pools, toilets, park landscaping stairs, night signs, passages, emergency exit walkways and the like.

The luminous tile according to the present invention can be a decorative tile that can not only serve as a building material indoors or outdoors, but also aesthetically sense at night, and can recognize the presence of an object by using the property of emitting light in the dark without turning on a light. In terms of safety can be secured.

In addition, it is possible to reduce the cost because it is possible to obtain sufficient effect even if a part of the tile is not installed, for example, in the form of a strip, pattern, etc., and it is suitable time even in the place where the advertisement is made by lighting up night neon signs. After using the lights for a while, the luminous effect can be used as a substitute for advertising, and can also be used to mark the driving line of the road.
