摘要: A method of preparing polyurea resin composition comprises forming a prepolymer by mixing about 50 parts by weight to about 80 parts by weight of a polyol, about 4 parts by weight to about 8 parts by weight of a dispersant, and about 20 parts by weight to about 30 parts by weight of a first monomer containing an isocyanate group; forming a first composition by mixing the prepolymer with about 2 parts by weight to about 4 parts by weight of a second monomer containing an amine group; stirring and emulsifying the first composition with about 100 parts by weight to about 200 parts by weight of a solvent; and forming a second composition by further adding about 0.2 part by weight to about 1.5 parts by weight of the second monomer to the emulsified first composition and stirring the resulting composition.

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.
