The present invention relates to a flame retardant photoluminescent glass tile. More specifically, in a photoluminescent glass tile in which a photoluminescent layer is formed on one surface of the plate glass, the photoluminescent layer is formed of a photoluminescent pigment composition in which a photoluminescent pigment is dispersed in an inorganic adhesive and a flame retardant photoluminescent glass tile, and a method of manufacturing the same. will be.

In the flame retardant photoluminescent glass tile of the present invention, a reflective layer and / or a foamed glass block layer may be further formed on the photoluminescent layer.

Generally, in many fields, such as building windows, furniture windows, and table glass, the plate glass is cut and used. However, since the actual size is not the same as that of the original plate glass, the pieces that have been cut and used according to the required specifications are left. The glass is thrown away as waste glass. In addition, the amount of industrial waste generated from the glass industry, such as bottle glass discarded after distribution and glass powder generated in various glass processing, is highlighted as a problem of environmental damage in society.

The prior art of recycling the scrap plate glass (hereinafter referred to as " waste plate glass ") generated in the conventional plate glass processing process has been disclosed (Republic of Korea Patent Application No. 2001-0085209; technology for making foamed glass beads by grinding waste plate glass). , Waste Glass Recycling-Foamed Glass Manufacturing Technology and Prospect; Prof. Chul-Tae Lee / Dankook University / prospects of indstrial chemistry.vol3.no.2.2000) Since a process, a blowing agent mixing process, a firing process, an annealing process, etc., a lot of equipment investment and energy must be used again, and there is a problem in that a lot of fine powder is generated in the process.

Meanwhile, a method of making glass tiles may be suggested as the easiest recycling method of waste plate glass, but conventionally, there was a limit of the amount of recycling due to the limitation of the use. In addition, the technology that adds the photoluminescent function to the back of the glass tile as a product with added value has been proposed, but it is a technology that uses an organic adhesive such as a polymer, so that it cannot withstand high temperatures, and it is toxic to human body in case of fire. There was a problem that occurred.

In addition, conventionally, any glass tile had a problem in actual use due to the thickness problem. For example, the conventional glass tile could not obtain the thickness which is easy to angle-work.

For example, when using 5 ~ 10mm thick glass tiles on the outer wall of the building, even if the glass is reinforced, there may be a risk of damage due to external blow.In the construction, a method of increasing the strength by attaching other materials to the back is required. The thickness which is easy to work was not obtained.

The present invention was devised to solve the above problems, and by forming a photoluminescent layer with a photoluminescent pigment composition in which a photoluminescent pigment is dispersed in an inorganic adhesive on a plate glass, no toxic gas is generated even in the event of a fire, and the photoluminescent effect even at a high temperature. An object of the present invention is to provide a photoluminescent glass tile having excellent flame retardancy and a method of manufacturing the same.

Another object of the present invention is to provide a flame retardant photoluminescent glass tile having excellent luminous luminance and a method of manufacturing the same by forming a reflective layer on the photoluminescent layer.

Still another object of the present invention is to provide a phosphorescent glass tile having excellent flame retardancy having a three-dimensional effect and two-tone effect by forming a three-dimensional pattern on the side of the plate glass, and a method of manufacturing the same.

Another object of the present invention is to provide a photoluminescent glass tile excellent in flame retardancy with improved strength by reinforcing plate glass and a method of manufacturing the same.

In addition, another object of the present invention is to provide a photoluminescent glass tile excellent in flame retardancy of various thicknesses and a method of manufacturing the same by adhering a foamed glass block to one side.

The photoluminescent glass tile having excellent flame retardancy according to the present invention is characterized in that in the photoluminescent glass tile having a photoluminescent layer formed on one surface of the plate glass, the photoluminescent layer is formed of a photoluminescent pigment composition in which a photoluminescent pigment is dispersed in an inorganic adhesive.

In addition, in the phosphorescent glass tile having excellent flame retardancy of the present invention, a foamed glass block layer may be further formed on the photoluminescent layer or the reflective layer.

The phosphorescent glass tile having excellent flame retardancy of the present invention may be prepared by cutting the plate glass to a predetermined size and then applying and drying the phosphorescent pigment composition on one surface of the cut plate glass.

It may be particularly useful as an emergency direction indicator or device for subways, underpasses, buildings, and the like. In addition, it can be usefully used for the purpose of displaying the location and direction for the visually impaired, and since the phosphorescent layer is not exposed to the outside, it can be used semi-permanently.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of a flame-retardant photoluminescent glass tile according to the present invention.

1 to 5, the flame-retardant photoluminescent glass tile according to the present invention is composed of a plate glass 100 and a photoluminescent layer 110, wherein the reflective layer 120 and / or foamed glass block layer 130 is Can be further formed. That is, as shown in FIG. 2, the reflective layer 120 may be formed on the photoluminescent layer 110 to increase the luminance of light. As shown in FIG. 3, the foamed glass layer 130 may be formed on the photoluminescent layer 110. By adhering, the thickness of the glass tile can be manufactured according to the standard. In addition, as shown in FIG. 4, both the reflective layer 120 and the foamed glass block layer 130 may be formed to increase reflection luminance and may be manufactured to a desired standard thickness. As shown in FIG. 5, the three-dimensional pattern and the photoluminescent layer 110 may be formed on the plate glass 100.

Hereinafter, the configuration of the flame retardant photoluminescent glass tile according to the present invention will be described in detail.

First, the main glass plate 100 may be used waste glass or genuine glass, but if only the appropriate size can be obtained waste glass is preferable in terms of environmental improvement. On the other hand, the thickness of the plate glass that can be used in the present invention is not significantly limited, but considering the three-dimensional pattern forming step is preferably 3mm to 10mm. If the thickness of the glass is too thin, problems may occur in the strength or pattern forming step, and if too thick, not only requires a long time when forming the pattern, but also increases energy consumption and is disadvantageous. Therefore, in the present invention, only waste plate glass having an appropriate size and thickness is selected and used as the main material, and the rest can be pulverized and used as a raw material for producing foamed glass, so that the collected waste glass can be used in its entirety.

The photoluminescent pigment used in the present invention may be a flame-retardant photoluminescent pigment described in Table 1 below, wherein the composition component is inorganic and composed at about 1300 ° C.

Table 1; Phosphorescent pigment composition example

ingredient Content: yellow-green light emitting material blue glow red glow Al2O3 41% 0.3% - SrO4 54% 56% - Eu2o3 0.7% 0.4% 0.1% CaS - - 95% CaSO4 - - 4% SiO2 0.3% 24% 0.3% Dy2o3 3.1% 6% One% Cao 0.22% 0.15% - MgO    - 11% - So3    - 0.03% - P2O5    - 0.025% - Etc slightly slightly slightly

The photoluminescent layer 110 is formed by applying a photoluminescent pigment composition in which a photoluminescent pigment is dispersed in an inorganic adhesive (or coating agent) and then drying. That is, by using an inorganic adhesive composed of inorganic particles, non-combustibility or flame retardancy is improved. In the present invention, the inorganic adhesive required to obtain a nonflammable or flame retardant effect is characterized in that the aqueous inorganic adhesive capable of low temperature curing. Existing general oil-based adhesive (coating material) of the coating material is burned when the temperature of about 200 ℃ is applied to the tile, toxic gas is generated, and when forming a reflective layer due to the spreading of the oil component, it is difficult to obtain a two-tone effect. Therefore, the present invention is characterized by using an adhesive (coating material) of an aqueous inorganic component capable of low temperature curing.

In the present invention, the inorganic adhesive includes silicon dioxide (SiO ₂₎ , aluminum oxide (Al ₂ O ₃₎ , calcium oxide (CaO), magnesium oxide (MgO), sodium oxide (Na ₂ O), and titanium dioxide (TiO ₂ ). A conventional inorganic adhesive obtained by dispersing the ceramic fine powder in an aqueous solution of an alkali silicate or a gel-like adhesive composed of inorganic fine powder (fine particles) and water.

Preferred examples of the composition of the inorganic adhesive are shown in Table 2 below. The adhesive composed of such a composition is aqueous, and is made in a sol state, but it is a kind of water glass-like composition and contains the glass component in the smallest particle state, so that it is cured in a short time at a temperature of about 200 ° C and has a strong adhesive force. In addition, since it has a surface hardness, it is advantageous in that it rarely reacts with other chemicals when used for the exterior of a building.

Table 2 (Example of composition)

ingredient Content (parts by weight) SiO2 10-15 Al2O3 20-30 CaO 0.5-2.5 MgO 0.02-0.05 Na2O 4 ~ 5 TiO2 0.01 ~ 0.07 moisture 35-55 Etc 7-10

The inorganic adhesive of the present invention is easy to mix with the photoluminescent pigment, and also easy to use mixed with the components of the reflective layer used as color scheme.

In addition, the inorganic adhesive of the above composition has the advantage that it does not burn even at a high temperature of about 800 ℃ to obtain the desired non-flammable or flame retardant, and also because it is an aqueous inorganic, there is no bleeding phenomenon during coating, it seems to have sprayed very small sand on glass It has the effect of making three-dimensional impression.

The photoluminescent layer according to the present invention converts the photoluminescent pigment composition in which the photoluminescent pigment is uniformly mixed with the inorganic adhesive into a highly concentrated gel form by repeatedly heating and cooling, and adjusting the concentration to 30 to 40 wt% by adding alcohol and water. It is formed from a photoluminescent pigment composition.

The photoluminescent pigment composition according to the present invention comprises the steps of: a) unpulverizing a photoluminescent pigment composition comprising a photoluminescent pigment; b) adding a silicate based material; c) heating and cooling are repeated to obtain a highly concentrated gel state; d) it can be formed by adding alcohol and water so that the concentration is 30 to 40% by weight to the gel.

Conventional photoluminescent pigments are not suitable for special purposes (e.g. subway emergency exit lights) because they have to burn at a temperature of about 200 ° C. when high heat is applied due to fire, etc., due to the use of oil-based resin series. Can be used to overcome this problem.

In general, the phosphorescent pigment is the most widely used yellow-green phosphorescent material because it is the brightest light when emitting light, in the present invention, by using a photoluminescent pigment as shown in Table 3 below by utilizing the transparency of the advantages of glass using a variety of blue and red phosphorescent materials Can be expressed in color.

Table 3; [luminescence luminance of phosphorescent materials with different emission colors; unit mcd / m2; based on German standard DIN67510]

Although the luminous effect of blue and red phosphorescent materials is much lower than that of yellow-green phosphorescent materials as in the above example, it is not a problem because the light emitting effect is not necessary for the practical use of tiles, and it can be used as a safety display panel. JIS Z 9107 is specified in accordance with the Japanese Fire Prevention Ordinance (No. 143 of the Tokyo Metropolitan Government) and the Ordinance of the Fire Prevention Ordinance (No. 281 of the Tokyo Metropolitan Rules No. 281 of 2016). The rate is set at 24 mcd / m 2 after 20 minutes of shading.

In the present invention, the inorganic adhesive and the photoluminescent pigment preferably have a mixing ratio of 5: 5. Therefore, even if one half of the unit area (m 2) is a photoluminescent pigment, the light emitting display ability as a safety display tile is sufficient for all three photoluminescent pigments.

Meanwhile, as illustrated in FIGS. 2 and 4, the reflective layer 120 may be formed on the photoluminescent layer 110. The reflective layer 120 is formed by coating the inorganic pigment composition on the photoluminescent layer 110 by spraying or the like, and drying the composition. An inorganic pigment may be used by mixing the inorganic pigment with the inorganic adhesive used when the photoluminescent layer 110 is formed. . As inorganic pigments, for example, titanium pigment (TiO ₂ ) powder is used as white pigment, cobalt oxide (CoO) powder is used as blue pigment, and ferric trioxide (Fe ₂ O ₃ ) powder is used as red pigment. Can be. Reflective layer 110 is to overcome the disadvantage that the light emission is weak due to the translucent layer of the photoluminescent layer to form a color coating layer on the photoluminescent layer to block the light from the back to obtain a higher luminous effect.

In addition, the photoluminescent glass tile according to the present invention preferably forms a three-dimensional pattern on one surface of the plate glass as shown in FIG. 5. The three-dimensional pattern may be formed using, for example, a conventional fusing method such as placing a plate glass on a heat-resistant ceramic plate having a desired pattern and heating it at 600 to 700 ° C. After the three-dimensional pattern is formed on one surface of the plate glass, the photoluminescent layer 110 and / or the reflective layer 120 is formed on the three-dimensional pattern to obtain a two-tone effect. When the three-dimensional pattern is formed on one surface of the plate glass in the present invention, the three-dimensional pattern may be formed on the whole (both sides) of the plate glass. When the three-dimensional pattern is formed as shown in FIG. 8 in which a picture photographing an embodiment of the glass tile including the three-dimensional pattern is formed, the aesthetics of the glass tile may be improved.

In addition, the glass tile according to the present invention may be combined with the foam glass block 130 to meet the standards regarding the thickness of the glass tile. In general, the thickness of the glass tile is about 3 to 5mm thinner than other stone or cement-based structures used for building exteriors. The glass tile according to the present invention can provide a finished glass tile having a thickness required for construction by forming and attaching a foam glass block 130 having the same thickness as the tiles on the rear surface of the glass tile at a predetermined thickness.

The manufacturing process of the foamed glass block is a well-known technique, for example, using waste glass fine powder having physical properties as shown in Table 4, and mixing inorganic materials and foaming agents such as carbons to increase the strength in a continuous firing furnace at about 700 ° C. By firing for about 4 hours to obtain a foam glass block. The foamed glass block 130 formed as described above is provided with a photoluminescent glass tile having a desired thickness and relatively light weight and having an appropriate strength by cutting and bonding it to a glass tile already made. 9 is a photograph of the side of an embodiment of a glass tile including a foamed glass layer configured as described above.

6 and 7, the manufacturing process of the flame-retardant photoluminescent glass tile of the present invention will be described.

As shown in FIG. 6, a process of cutting the pane to a desired tile size is performed. Next, the photoluminescent layer 110 is formed on one surface of the plate glass 100, or a three-dimensional pattern is formed on one surface of the plate glass, and then the photoluminescent layer is formed.

The three-dimensional pattern may be formed by using fusing. First, place the plate glass 100 on the pattern frame in the firing furnace and gradually raise the temperature to 600 ~ 700 ℃ (takes about 1 ~ 2 hours). As the glass starts to melt, the glass pattern is formed as the pattern of the pattern frame placed at the bottom of the glass. Then, immediately moved to a slow cooling process and the temperature is lowered to room temperature, the desired pattern is formed on the plate glass 100.

The photoluminescent layer 110 is coated on one surface of the plate glass 100 with a photosensitive pigment composition in which a photoluminescent pigment is dispersed in an inorganic adhesive, and then dried to form a photoluminescent layer 110. The photoluminescent layer 110 adds alcohol and water so that the concentration of the photoluminescent pigment composition is 30 to 40% by weight, and then preheats the plate glass to about 80 ° C. and coats it by spraying or the like. Drying for ~ 10 minutes can form a photoluminescent layer free from scratches, decomposition, discoloration and deformation due to bonding strength, fusion, and fluxing by CaO, Na2O, TiO ₂ and trace inorganic additives. Coating, such as spraying can be performed several times repeatedly.

In addition, after the process of forming the photoluminescent layer, a process of forming the reflective layer 120 which is an inorganic pigment layer on the photoluminescent layer may be performed. That is, the inorganic pigment used in the photoluminescent layer 110 is used as a binder to disperse the inorganic pigment, and then coated on the photoluminescent layer 110 by spraying, and then dried to form the reflective layer 120. The binder may be an inorganic adhesive used in the composition of the photoluminescent pigment composition. Reflective layer 120 is to overcome the disadvantage that the light emission is weak due to the translucent layer of the photoluminescent layer 110 to add a color coating on the photoluminescent layer 110 to block the light from the back to a higher luminous effect And a two-tone stereo effect. As a technique used to obtain the two-tone effect, as shown in FIG. 7, the photoluminescent layer 110 is first coated by using the inclined surface of the pattern, and then the reflective layer 120 is coated, respectively, in the opposite direction from 30 to 40. It can be obtained by spray coating at an oblique angle with the inclination angle of FIG. That is, as shown in FIG. 7 by spraying the photoluminescent pigment composition in a direction inclined at an angle of about 30 to 40 degrees at the coating surface by utilizing the inclined surface of the pattern, it is dried to form a photoluminescent layer 110, the photoluminescent layer Spraying the inorganic pigment in the direction inclined about 30 to 40 degrees in the direction opposite to the (110) spray direction, and then dried to form a reflective layer 120 can obtain a two-tone stereoscopic effect.

In addition, the coating method is not particularly limited, but by employing a spray method, a certain amount of water is scattered and evaporated while being sprayed from the spray apparatus to the plate glass 100 so that the inorganic coating film can enter the curing step quickly, such as oily. The effect of preventing the surface spreading phenomenon can be obtained.

In the present invention, the plate glass 100 is preferably composed of tempered glass. The strengthening of the glass preferably forms a three-dimensional pattern and then performs a glass strengthening process. In the present invention, since the photoluminescent layer and the reflective layer are flame retardant inorganic materials, the photoluminescent layer or the reflective layer may be strengthened by performing a heat treatment reinforcement process.

On the other hand, after forming the photoluminescent layer 110 or the reflective layer 120 to form a glass tile having a predetermined thickness, the foamed glass block formed to a predetermined thickness may be bonded using an inorganic adhesive. That is, by manufacturing a foam glass block in accordance with the thickness of the glass tile for use as a building material, by using an inorganic adhesive on the plate glass surface on which the photoluminescent layer 110 or the reflective layer 120 is formed, various thicknesses as building materials Can be satisfied.

The method may further include a step of heating and fusion after bonding using the inorganic adhesive.

According to the flame-retardant photoluminescent glass tile according to the present invention and a method for manufacturing the same, the photoluminescent layer is formed of a photoluminescent pigment in which a photoluminescent pigment is dispersed in an inorganic adhesive, thereby maintaining a photoluminescent effect even at high temperatures of 700 to 800 ° C. The light emitting brightness is improved by forming a reflective layer composed of an inorganic pigment composition, and a three-dimensional pattern is formed to have a three-dimensional effect and a two-tone effect on the glass tile, thereby improving the aesthetics. By adhering the foamed glass layer to one side, it is possible to provide a flame retardant photoluminescent glass of any thickness. The flame retardant photoluminescent glass tile according to the present invention is composed entirely of inorganic material and is excellent in nonflammability or flame retardancy. In addition, the phosphorescent glass tile excellent in flame retardancy of the present invention can be installed as a tile of the floor or wall of the building, as well as emergency direction indicators such as subways, underpasses, buildings, etc. It can be usefully (permanently) permanently as a device, and also useful for location and orientation purposes for the visually impaired.
