The invention discloses a method for recycling, regenerating and reusing waste paint residues. Water-containing waste paint residues and dry waste paint residues are included. The method comprises a method A for recycling, regenerating and reusing the water-containing waste paint residues and a method B for recycling, regenerating and reusing the dry waste paint residues. The method A comprises the following steps: volatilizing water, smashing the residues into dry powder of 500-1,000 meshes, dissolving into aqueous paint, grinding the aqueous paint, filtering the aqueous paint by a filtering net with the fineness of 450-650 meshes, modulating the color, adding a colorant into the filtered aqueous paint during stirring, stewing for 72 hours, and removing oil dirt to obtain a finished product. The method B comprises the following steps: performing dissolving, grinding, filtering and viscosity adjustment, performing secondary color modulation, adding filtered paint into a reaction kettle, and adding a solvent colorant during stirring to obtain a finished product. The water-containing waste paint residues and the dry waste paint residues are respectively treated; by use of the different physical properties and the dissolving capacities, the water-containing waste paint residues and the dry waste paint residues can be both turned into treasures and can be reasonably collected; the phenomenon that the waste paint residues pollute the air, the soil and the working environment can be completely treated, and the method is a powerful guarantee for environmental treatment.
