The present invention relates to a photoluminescent coating composition and a floor covering using the same, and more particularly, a photoluminescent coating composition comprising alumina-based photoluminescent pigment, illite and bamboo vinegar solution, and using the same on a surface of an interior finishing material in an emergency situation. Regardless of power failure, it can be used as a safe induction indicator in the room, while maintaining the beauty by keeping the printed pattern on the floor surface as it is, it emits far infrared rays, negative ions and provides deodorizing and antibacterial effects to make the indoor environment pleasant. It is related with the functional flooring which can do it.

Recently, as interest in environmental pollution gradually expands to an indoor environment, development of a building finishing material that can create a comfortable indoor environment is actively progressing.

As part of this, in the case of finishing materials used indoors among building finishing materials, it is manufactured by mixing ceramics that emit far infrared rays or by coating the coating material with ceramic components on the surface of the finishing materials, which is harmful to human body by the effect of far infrared rays emitted from these components. Many functional building finishes are being released that can decompose or remove substances or promote physiological activity in the human body.

In recent years, luminous or photoluminescent materials have been used in building finishing materials to serve as guidance guides for escaping from inside the building in dangerous situations.

However, in the case of manufacturing the above-described finishing material and a mixture of the ceramic component emitting far-infrared rays of the finish material is treated with a paper medium or a sheet on the surface, there is a disadvantage that the far-infrared radiation effect is sharply lowered due to their shielding effect, In the case of coating a ceramic component on the surface of the finish by mixing the coating, there has been a problem that a sufficient effective amount cannot be used because it affects the coating film formation and the strength of the coating. In particular, in the case of a luminous or photoluminescent material, when used together with a ceramic component, the resin component, which is a main component of the coating film, is excessively diluted to reduce workability, and after the coating layer is formed, the coating layer is easily removed from the surface of the finishing material. come.

Accordingly, the present invention uses a photoluminescent pigment, bamboo vinegar and illite excellent in afterglow brightness, afterglow time and light resistance, etc. in a transparent resin, as a safety induction indicator means for indoors regardless of power outages in case of emergency, The purpose of the present invention is to develop a photoluminescent coating composition which can make the indoor environment comfortable by releasing far infrared rays, anions, providing deodorization and antibacterial effects while maintaining beauty by using the printed layer as it is.

Accordingly, it is an object of the present invention to provide a photoluminescent coating composition prepared by mixing a photoluminescent pigment, a bamboo liquor solution and an elite of an alumina component doped with a rare earth element in a transparent resin in a specific blending ratio.

By providing a functional flooring that can make the indoor environment comfortable.

However, the use of the photoluminescent coating composition of the present invention is not limited to flooring materials, and can be used for other interior finishing materials.

At this time, the method of coating the floor will be apparent to those skilled in the art of the present invention will be omitted.

In addition, the transparent resin used in the present invention has excellent mechanical properties and elongation that can cushion external impact so that the surface of the flooring material can be prevented from being damaged by surface pressing such as being pressed by a heavy weight or being taken or scratched by a sharp object. It is preferable to use a transparent resin capable of beautifully expressing the light emitted from the photoluminescent pigment and the pattern neck. Specifically, UV paint, melamine resin, acrylic resin, phenol resin, polyvinyl chloride resin, polyethylene resin, poly Propylene resins, polyethylene terephthalate resins, polyethylene telephthalate glycol resins, acrylonitrile butadiene styrene resins, polyurethane resins, styrene butadiene styrene block copolymer resins, styrene ethylene butylene sterol block copolymer resins or mixed resins thereof It is preferable.

In addition, the present invention may further provide a floor covering material having increased durability against photoluminescence by further forming a surface protective support layer made of a transparent resin on the photoluminescent coating layer formed on the surface using the photoluminescent coating composition of the present invention.

However, the transparent resin used in the present invention is not limited to the resin described above, and any resin may be used as long as it is a resin meeting the object of the present invention.

In addition, the photoluminescent pigment used in the present invention is a rare earth element, preferably rare earth selected from the group consisting of europium (Eu), gadolinium (Gd), dysprosium (Dy), terbium (Tb) and ytternium (Yb). An inorganic photoluminescent pigment, which is a composite of an alumina component of an alkaline earth metal doped with an element, is used, and the composite of the alkaline earth metal alumina component is aluminum oxide (Al 2 O 3), potassium oxide (CaO), strontium oxide (SrO), or magnesium oxide. As a complex of salts consisting of (MgO), complexes of salts such as Al ₂ O ₃ CaO, Al ₂ O ₃ MgO, SrAl ₂ O ₄ , SrAl ₂ O ₄ (OH) or Al ₂ O ₃ CaOSrOB ₂ O _3, etc. can be used. Preferably, in the present invention, it is preferable to use a photoluminescent pigment of an alumina component (Al ₂ O ₃ -SrO ₃ -B ₂ O ₃ ) doped with a rare earth element. This is because the photoluminescent pigment of the composite doped with the earth element has excellent photoluminescence performance for afterglow brightness, afterglow time, and light resistance, and can emit far infrared rays and anions that are beneficial to the human body. In addition, in the present invention, when less than 10 parts by weight of the photoluminescent pigment is used based on 100 parts by weight of the transparent resin, the photoluminescent effect is reduced, and when used in excess of 40 parts by weight, the transparency of the transparent resin is lowered to sufficiently express the pattern of the flooring material.

In the photoluminescent paint of the present invention, the bamboo vinegar solution contains a large amount of acids such as acetic acid and formic acid, and phenols such as phenol, cresol, and guayacol, and provides a deodorizing power by masking or deodorizing strong odors and containing them in bamboo. Its function is to keep the floor clean by keeping bacteria from being contaminated or infected by bacteria due to the action of strong antibacterial substances. If the amount is less than 5 parts by weight based on 100 parts by weight of transparent resin, If the amount is more than 10 parts by weight, the transparent resin is excessively diluted to increase the drying time, thereby deteriorating workability.

In addition, in the present invention, illite is neutralized by adsorbing heavy metals, toxic substances and toxic gases together with bamboo vinegar solution, and releases a large amount of negative ions and far infrared rays together with photoluminescent pigments to facilitate metabolism in the body and toxins. Synthesis provides a synergistic effect to make the interior space comfortable by using less than 5 parts by weight based on 100 parts by weight of the transparent resin, the above-mentioned effects are insignificant, and when used in excess of 10 parts by weight of the light-emitting coating layer Since it falls, it is preferable to use within the use range mentioned above.
