The present invention relates to a method of manufacturing a plate-like finishing material (60), which is a main material of urethane, in which a urethane resin is sprayed onto a conveyor (10) to continuously form a urethane plate (19) And the binder aggregate 35 in which the urethane chip 31 and the sandpaper 32 are mixed and the binder are charged into the mold 50 to form a plate-like finishing material 60. According to the present invention, it is possible to finely and uniformly form the particle size of the urethane aggregate constituting the plate-like finishing material, thereby remarkably improving the flatness, elasticity and durability of the urethane plate-like finishing material, Can be obtained. |
