Water-based paint spraying process for wheels

The invention belongs to the technical field of wheel spraying, and relates to a wheel water-based paint spraying process which comprises the following steps: removing oil on the surface of a wheel, and performing sand blasting or polishing to remove rust on the surface of a hub; spraying a resin coating on the surface of the wheel, and baking and curing to form a coating layer; grinding the surface of the wheel; preparing a water-based paint coating, controlling the viscosity to be below 300mPa. S, and controlling the working environment temperature to be 15-40 DEG C; after the water-based paint coating is sucked into a spraying device, spraying is conducted on the surface of the pretreated wheel for at least two times, and spraying is conducted for the second time when the first primer is dry and not sticky to hands; and naturally airing the wheel sprayed with the water-based paint coating or curing at the temperature not higher than 40 DEG C. Water is used as a solvent, so that a large amount of resources
