Abstract
The invention provides a plastic part coating process of an electric vehicle and relates to the technical field of coating processes. The plastic part coating process of the electric vehicle comprises the steps of firstly cleaning oil stains and dust on the surface of a plastic part, enabling the surface of the plastic part to be smooth through sanding and polishing so as to facilitate coating of a coating layer; then performing first-time primer spraying and second-time primer spraying, supplementing red plaster on the plastic part and then performing plaster scraping and drying; performing first-time polishing, then performing drying treatment, part installation and finish spraying after polishing is finished and finally performing soaking treatment. A traditional coating mode is changed, twice primer spraying is adopted, a refrigerating fluid soaking working procedure is performed, the product coating layer quality is improved, coating working procedures are decreased, the coating cost is reduced, and the plastic part coating process has very good actual application significance.
