A method for manufacturing a high-glossy synthetic resin sheet is provided to produce high-glossy synthetic resin sheets having durability and water resistance without going through a complex coating process. A method for manufacturing a high-glossy synthetic resin sheet includes the steps of: (S11) mixing 100% by weight of phenol-melamine co-condensation resins, 20% by weight of a dispersant, and 5% by weight of a releasing agent, and impregnating an original paper in a first impregnation bath containing the mixture using a 60 mesh roll; (S12) mixing 100% by weight of phenol-melamine co-condensation resins, 5% by weight of a weakly acidic nanosilver having a concentration of 1000 ppm and an average particle size of 5-20 nm, 5% by weight of methyl ethyl ketone, 70% by weight of titanium oxide, and 0.8% by weight of a hardener, and impregnating the first impregnated original paper in a second impregnation bath containing the mixture using a 60 mesh roll; (S13) blending 100% by weight of melamine resins, 5% by weight of an anti-crack additive, 0.8% by weight of a hardener, and 0.7% by weight of a releasing agent, and impregnating the second impregnated paper in a third impregnation bath containing the blend using a 40 mesh roll; (S14) mixing 100% by weight of melamine resins, 5% by weight of an anti-crack additive, 1.0% by weight of a hardener, and 5% by weight of a releasing agent, and impregnating the third impregnated paper in a fourth impregnation bath containing the mixture using a 40 mesh resin coating roll; and (D) drying the impregnated paper through a drying line having a temperature of 130 °C and a transfer speed of 40 m/minute after each impregnation step.
