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.

Description

technical field [0001] The invention relates to the technical field of coating technology, in particular to a coating process for plastic parts of electric vehicles. Background technique [0002] As an important energy source with environmental protection, cleanliness and high conversion rate, electricity is widely used in production and life. Electricity is used as an application to drive the replacement of vehicles, promote the low-carbon development of the transportation industry, reduce transportation costs, and save energy. Environmental protection is one of the important research topics in the world. After decades of development, it has been used in electric urban public transport vehicles, factory and mine electric transport vehicles, electric urban sanitation cleaning vehicles, engineering, tunnels, special vehicles for subway construction, etc. field. [0003] Automobiles have been used for quite some time as people's traditional means of transportation, but automo...
