Description

Luminescent paint composition and vinyl sheet flooring coated the same}

The present invention relates to a photoluminescent coating composition and a vinyl flooring material using the same, and more particularly, to a photoluminescent coating composition obtained by mixing alumina-based photoluminescent pigments and elites, and using the same on a surface of an interior finish material for electrostatic discharge in an emergency situation. Regardless of whether it is used as a safety guide for indoors, it can prevent safety accidents and reduce the use of lamps, contributing to energy saving, while maintaining the beauty by keeping the printed floor of the floor surface pattern intact. In addition, the present invention relates to a functional vinyl sheet material that can release anions, provide deodorizing and antibacterial properties, and make the indoor environment comfortable.

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 addition, recently, luminous or photoluminescent materials have been used for building finishing materials to play a role of guide guidance for escaping from inside a building in a dangerous situation.

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, since there is no photoluminescent effect in the dark, it is not possible to prevent safety accidents in case of sudden power failure or accident, or to conserve energy by reducing the use of lamps, and to cope with the indoor environment such as dark caused by short circuit and fire. none.

Functional vinyl sheet material has been developed.

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

In addition, it may be coated or molded on a conventional substrate of PP, PE, PVC sheet used in the photoluminescent coating composition of the present invention and may be incorporated into the substrate. At this time, the method of coating on the vinyl flooring material 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 preferably uses a transparent resin that can be beautifully expressed in the light and veneer emitted from the photoluminescent pigment of the vinyl flooring material, specifically, the transparent resin is UV paint, melamine resin, acrylic Preference is given to using resins, phenolic resins, polyvinyl chloride resins, polyethylene resins, polypropylene resins, polyethylene terephthalate resins, acrylonitrile butadiene styrene resins and polyurethane resins.
