PURPOSE: An aqueous resin composition for a vehicle is provided to have excellent hardness, coating adhesion, water resistance and acid resistance by containing a blocked hexamethylenediisocyanate and 2-hydroxyethylmethacrylate copolymer. CONSTITUTION: An aqueous resin composition comprises 300 wt% of a blocked hexamethylenediisocyanate, 2-hydroxyethylmethacrylate copolymer, 240 wt% of a viscosity controller, 60 wt% of a butanol, 60-70 wt% of an acrylic acid, 50 wt% of a hardener, 280-290 wt% of an acrylic resin, 30 wt% of styrene, 20 wt% of an initiator, 70-80 wt% of an aqueous agent, and 510-520 wt% of distilled water. The blocked hexamethylenediisocyanate is blocked by 3,5-dimethylpyrazole. |
