摘要: A resin composition preparation apparatus and a polyurea resin are provided. A resin introduction unit is configured to inject a composition solution and air mixed in the composition solution. An air bubble generator is connected to the resin introduction unit. An air bubble separation tank is connected to the air bubble generator. The air bubble generator comprises: an inlet through which the composition solution and the air are introduced from the resin introduction unit; an outlet through which the resin composition is discharged to the air bubble separation tank; and an internal flow channel connecting the inlet and the outlet so as to pass therethrough. The internal flow channel comprises a groove portion configured to form the air bubbles having a smaller particle size than that of the air.
