The invention provides an environment-friendly water-based paint capable of quickly decomposing formaldehyde. The environment-friendly water-based paint comprises the following components in parts by mass: 45-55 parts of alkyd resin; 25-35 parts of a solvent; 15-25 parts of color paste; 0.5 to 0.8 part of a defoaming agent; 1.0 to 1.5 parts of a dispersant; 5-15 parts of a curing agent; 5 to 15 parts of Pt/Bi2O3 powder; the Pt/Bi2O3 powder is added into the environment-friendly water-based paint capable of quickly decomposing formaldehyde, the Pt/Bi2O3 powder can degrade gaseous formaldehyde on the outer side of a paint surface and reduce the concentration of the formaldehyde on the outer side of the paint surface under the same action of room temperature and indoor illumination, so that outward volatilization of the formaldehyde on the paint surface is accelerated, the volatilized formaldehyde can be continuously decomposed by the Pt/Bi2O3 powder, and the formaldehyde can be quickly decomposed by the Pt/Bi2O
