Floor material having nano hybrid UV coating layer

A flooring material having a nano-hybrid UV coating layer, the flooring material comprising:

• a floorboard layer having a shape of a plate;
• a decorative film layer laminated on an upper surface of the floorboard layer to provide patterns and colors;
• and
• an ultraviolet (UV) coating film layer provided in the form of a film, including a UV coating layer hybridized with nano-silica on an upper surface thereof to provide scratch resistance and stain resistance, and laminated on an upper surface of the decorative film layer,
• wherein the UV coating film layer further includes a base film layer and the UV coating layer hybridized with the nano-silica is disposed on an upper surface of the base film layer,
• wherein the UV coating layer hybridized with the nano-silica includes a UV coating solution,
• wherein the UV coating solution includes a urethane acrylate resin and the nano-silica,
• wherein the urethane acrylate resin and the nano-silica of the UV coating solution include a mixture of 400 to 520 parts by weight of polyester polyol, 280 to 350 parts by weight of isophorone diisocyanate, and 520 to 630 parts by weight of nano-silica-hybridized 2-hydroxyethyl acrylate, and a viscosity modifier, an antifoaming agent, a dispersant, a reaction catalyst, and a surface modifier, and
• wherein the polyester polyol includes a condensate of 200 to 250 parts by weight of adipic acid, 55 to 75 parts by weight of propylene glycol, 80 to 96 parts by weight of diethylene glycol, and 70 to 90 parts by weight of 1,6-hexanediol.
