The present invention provides a composition for a double-component waterborne coating which has the following advantages: high stability in long-term storage, excellent initial water resistance and luster of coating, and environment-friendly performance. The composition for the double-component waterborne coating comprises the following components: (A) waterborne acrylic resin with carboxyl; and (B) carbodiimide compound. The carbodiimide compound comprises polyelhylene glycol monoalkyl ether residues of which repetition number q of glycol is 6-40 and polyethylene glycol monoalkyl ether residues of which repetition number r of poly(propylene glycol) is 4-14, wherein, the molar ratio between the polyelhylene glycol monoalkyl ether residues and the polyethylene glycol monoalkyl ether residues is 1:1 to 1:15. |
