Description
The present invention relates to a paint composition with improved visibility and a roof structure of a bus stop to which the coating is applied, and more particularly, to allow a driver to clearly understand structures such as a bus stop at day and night, and to provide excellent afterglow brightness to the structure. And it relates to a coating composition with improved visibility to provide afterglow time and a roof structure of the bus stop applying the same.
Among the optical phenomena of the material, luminescence phenomena other than temperature radiation and Cherenkov radiation are collectively called luminescence, and are generally classified into fluorescence and phosphorescence.
The phosphor is instantaneous luminescence phenomena compared to the phosphor, refers to the portion of the light emitting intensity does not have a significant temperature dependence, the temporal change necessarily appears exponential, it is classified as a relatively short time in terms of emission time, It is not necessarily classified as light emission time, but refers to high luminance while an energy source is present.
The phosphor is referred to as the luminescence remains even when the stimulus source is removed in contrast to the phosphor, and can be distinguished from the phosphor by the emission time, but the limit is unclear, the intensity and decay time change due to temperature or environment is large, attenuation In many cases, the exponent is not functional.
Both of these phosphors and phosphors are applied to a place where the naked eye needs to be identified at night or in the dark, such as a safety sign or a clock face.
The phosphor and the phosphor are not clear, but can be mainly distinguished by an afterglow time, and a phosphor having a long afterglow time even when the energy source is removed may have a wider use than the phosphor.
Conventional phosphorescent pigments having a phosphorescent property is a zinc sulfide-based photoluminescent pigment mainly composed of zinc sulfide to which a small amount of copper is added, which has a low afterglow effect. In other words, not only is the afterglow luminance that emits light in a dark place by itself after accumulating light, but also afterglow time is short within about 1 hour. More importantly, when used outdoors, weather resistance is poor and the afterglow effect is lost within 1 to 2 weeks. Therefore, zinc sulfide-based photoluminescent pigments are rarely used in real life because they are not commercially available except in exceptional cases.
On the other hand, when the afterglow effect is to be maintained for a long time, it is possible to use a light-emitting paint prepared by mixing the conventional photoluminescent pigments such as tritium, promethium-147, ranium-266 and the like. However, since it uses radioactive materials, the human body may be seriously damaged if exposed to the human body, so strict caution is required for handling. In addition, since the photoluminescent pigment containing the radioactive material is expensive to dispose of the use tools or cleaning waste water, the use area is limited.
Therefore, in order to solve such a problem, Korean Patent Publication No. 1997-0070139 (published on November 07, 1997) is safe and easy to use in real life regardless of outdoors or indoors, and does not contain radiation substance. The photoluminescent coating composition which is harmless to a human body, is excellent in afterglow effect and weather resistance, and is made to apply to any to-be-coated object is disclosed.
The photoluminescent coating composition is 10 to 90% by weight of an inorganic photoluminescent pigment which is activated by ions of rare earth metals and is an alkaline earth metal aluminate complex composed of a complex of aluminum oxide and a salt consisting of calcium oxide, strontium oxide or magnesium oxide, and the photoluminescent pigment. 5 to 50% by weight of a binder for imparting adhesion between the object and the coating material, 0.1 to 1% by weight of a wet dispersant for aiding dispersion and wetting of the phosphorescent pigment, and an antisettling agent for preventing sedimentation of the phosphorescent pigment during storage of the paint It consists of 10 to 90% by weight of a colorant comprising 0.5 to 5% by weight, antifoaming agent 0.1 to 1% by weight and solvent 4.3 to 40% by weight.
However, in the case of the photoluminescent paint composition, since an inorganic sedimentation inhibitor such as aerosol and bentonite is used to prevent the sedimentation of the photoluminescent pigment, there is a problem in that the phosphorescent property of the photoluminescent paint is significantly reduced.
Accordingly, it is a first object of the present invention to provide a coating composition having improved visibility of water resistance and shape stability after application, excellent brightness for both day and night, and high brightness maintained for a long time.
In addition, a second object of the present invention is to provide a roof structure of a bus stop having excellent brightness and improved visibility of maintaining high brightness for a long time at both day and night.

In addition, in order to achieve the second object of the present invention, according to one embodiment of the present invention, a paint comprising a gel coat 15 to 55% by weight, photoluminescent pigment 20 to 45% by weight, and fluorescent pigment 20 to 40% by weight It provides a roof structure of a bus stop to which the composition is applied.
The coating composition according to the present invention has the effect of the luminescence characteristic of the fluorescent pigment and the luminescence characteristic of the photoluminescent pigment at the same time has the effect of identifying the coated structure under any conditions of day and night. In addition, when the coating composition according to the present invention is applied to structures such as guide signs, roofs of bus stops, afterglow luminance and afterglow time of the structures are improved. In addition, the coating composition of the present invention has high water resistance and high shape stability after application.
The roof structure of the bus stop coated with the coating composition according to the present invention has an effect of generating high brightness for both day and night so that the bus driver can accurately recognize the bus stop.
