Meanwhile, according to the present invention, it is preferable that a heat shielding layer is formed on the outer surface of the black box body 100 . In this case, the heat shield layer is formed by coating the heat shield layer with a predetermined thickness with a coating composition that implements heat insulation and heat shielding performance.

In this case, the coating composition is a main raw material obtained by adding 0.25 to 0.5 liters of a lightweight insulating filler to 1 liter of mixed raw material in which an inorganic binder and a bisphenol-based epoxy resin are mixed in a weight ratio of 1.5:1; It is composed by mixing 90-95% by weight of the main raw material and 5-10% by weight of water.

Here, blast furnace slag fine powder is used as the inorganic binder, because it contributes to improvement of durability and functionality.

In addition, the reason for using the bisphenol-based epoxy resin is that it has excellent stability against ultraviolet (UV) and can improve heat shielding performance. In particular, 25 g of cesium tin oxide (CsSnO) and _{20 g of strontium carbonate (SrCO 3} ) may be further added by pulverizing them in the form of nanopowders to further improve insulation and heat shielding performance by blocking the infrared region. At this time, cesium tin oxide increases the infrared blocking rate to 60%, and strontium carbonate increases the powder smoothness of the coating surface to increase the reflective ability by birefringence, thereby strengthening the heat shielding and insulating functions.

On the other hand, the lightweight insulating filler uses a porous ceramic alumina. This porous ceramic alumina is a water-soluble insulator compared to conventional amorphous silica, expanded pearlite, and kaolin, and has a thermal conductivity of 0.037 W/mK, so it has excellent thermal insulation performance, and excellent heat reflection and heat resistance. In particular, INSULADD, the main component, forms a ceramic heat insulating layer on the surface in the form of a ceramic powder of a fine circular hollow body, thereby exhibiting high heat reflection and heat resistance performance, and blocking heat to increase heat insulation performance.

In addition, if the black box body is coated with a non-combustible insulating material that does not burn with inorganic ingredients, it can help to prevent the spread of flames in case of fire. , and water repellency.

In addition, in the present invention, a photoluminescent paint may be further applied to a part of the black box body.

Phosphorescent paint is _{a crystal with SrAl 2} O ₄ as a mother crystal, and it is a material that emits light for a long time.

The photoluminescent paint according to the present invention is completed by adding and mixing 50 parts by weight of a phosphorescent powder, 20 parts by weight of an amine curing agent, 20 parts by weight of blast furnace slag fine powder, and 5 parts by weight of a pigment, followed by mixing with respect to 100 parts by weight of the epoxy resin.

Here, the blast furnace slag fine powder contains calcium carbonate as a main component, and is added for dimensional stabilization as well as for controlling the strength and voids of the paint. And, the amine curing agent is added to promote the curing properties of the paint. In addition, both organic and inorganic pigments can be used for the pigment, which is commonly known or can be purchased and used in the market. That is, there is no need to limit the description in particular because it is for giving a color.

In addition, the photoluminescent powder is pulverized to a particle size of 10 nm or less in a state in which the content of _{strontium aluminate (SrAl 2} O ₄ ) is increased by heating the ceiling stone to remove impurities, and strontium aluminate _{(SrAl 2} O ₄ ) is used in the ceiling stone. It is known to contain about 30-50%, and it is reported that the surface energy of _{strontium aluminate (SrAl 2} O _{4 ) increases when the particle size is nano-sized.} Therefore, when impurities affecting the afterglow luminance are removed _{, the content of strontium aluminate (SrAl 2} O ₄ ) is relatively high by the amount of the disappeared impurities.

In particular, it is preferable to use the photoluminescent powder prepared as follows. For example, a first step of crushing the sky ore to a particle size of 50 mm or less, a second step of putting the mill ore crushed in the first step into a heating and drying furnace and calcining at 800-1200° C. for 3 hours at reduced heat; A third step of pulverizing the reduced-calcined celestial ore through the second step with a nano pulverizer, and a fourth step of sieving and selecting only the particle size of 10 nm or less from the pulverized product pulverized through the third step; can be used

At this time, the reason for crushing the celestial ore to a particle size of 50 mm or less in the first step is to increase the effect of calcination by heating loss. That is, it is more efficient to process small-volume objects than large-volume ones.

In addition, the heating and drying furnace used in the second step is a rotary kiln, which is configured to be rotary heated and fired with strong hot air. This is to burn or volatilize impurities contained in the sky ore, especially substances that inhibit the luminance of the afterglow, while heating up to 1200°C before it is completely dissolved in the liquid phase because the sky ore is dissolved at 1300 ° C. Because. In particular, since the hot wind is blowing, the impurity removal efficiency is very excellent.

And, the nano grinder used in the third step is a vertical bead mill, and the raw material is put into the lower part of the container to separate the beads and the raw material in the upper separator, and the fine raw material is discharged through the outlet, and the granule The raw material is dropped into a container along with the beads, and is an equipment configured to maximize the dispersion and pulverization functions. Here, the separator is a centrifugal gap-less type, and has an advantage in that the final particle size of the raw material can be made nano.

In addition, with respect to 100 parts by weight of the sorted material selected in the fourth step, 4.5 parts by weight of lithium nitrate having a particle size of 10 nm or less and 3.5 parts by weight of waste glass powder having a particle size of 10 nm or less may be further added and mixed. At this time, lithium nitrate is to increase the ion exchange property of the photoluminescent paint to increase dispersion stability, and the waste glass powder is to increase the afterglow luminance.

Furthermore, in the present invention, when the photoluminescent powder is made into a paint, the tensile strength and adhesion strength are lowered, which may cause a phenomenon in which the life of the paint is shortened due to interfacial separation and lifting after painting. To prevent this, in the present invention, based on 100 parts by weight of the epoxy resin, 5.5 parts by weight of methacresol, 3.0 parts by weight of sodium bicarbonate, and 2.5 parts by weight of petroleum sulfonate may be further added.

In this case, methacresol inhibits interfacial separation through the anchoring function between the paint and the adherend, and sodium bicarbonate allows the adhesion and fixation to be maintained for a long time even after a certain period of time due to the high crosslinking density, and petroleum Sulfonates can enhance chemical resistance and chemical resistance while preventing discoloration. In addition, in the present invention, 1.5 parts by weight of platinum nanopowder and 2.5 parts by weight of oregano oil may be further added to 100 parts by weight of the epoxy resin in order to increase the antimicrobial properties of the photoluminescent paint. At this time, platinum nanopowder is added to obtain the effect of blocking and sterilizing bacteria, pathogenic microorganisms, and viruses because it has excellent far-infrared radiation effect and antibacterial power; Oregano oil is added to enhance antibacterial properties against common contaminants.

As described above, the present invention has been shown and described in relation to specific embodiments, but it is known in the art that various modifications and changes are possible without departing from the spirit and scope of the invention as defined by the claims. When you grow up, anyone will find out easily.
