The invention provides a high-brightness silver wheel water-based
coating process, which belongs to the technical field of wheel
coating, and comprises the following steps of material pretreatment, bottom
powder spraying, bottom
powder curing,
polishing and purging, preheating, water-based primer spraying, flash
drying and leveling, water-based high-brightness silver paint spraying, flash
drying, leveling and cooling, bright
powder spraying and paint film curing. And an
infrared resonance rapid flash-
drying process is adopted after the water-spraying primer and the water-spraying high-brightness silver paint are subjected to flash-drying. According to the water-based
coating process for the high-brightness silver wheel, an
infrared resonance rapid flash-drying process is provided based on the difference between the
resonance frequency of water molecules of water paint and the resonance frequency of
organic film-forming matter molecules, and the problems that water-based primer is completely sprayed, high-water-content high-brightness silver and high-water-content primer are subjected to wet-on-wet operation, bottom
biting is caused, and gloss loss is caused are solved; the appearance
color consistency, high brightness, ultra-fine texture and paint film reliability of different positions of the high-brightness silver wheel are guaranteed, and VOC of construction is reduced.
