The invention discloses a corrosion-resistant coating treatment method for the surface of an automobile. The corrosion-resistant coating treatment method comprises the following steps that S1, polishing is conducted, specifically, the surface of the automobile is subjected to grinding and polishing treatment; the surface of the automobile is washed 2-3 times through flowing high-pressure steam, then the surface of the automobile is washed 2-3 times through dust-free high-pressure airflow, and the washing/brushing sequence is from top to bottom; s3, electrophoretic coating is conducted, specifically, the surface of the automobile is coated with electrophoretic paint, and an electrophoretic layer is formed; s4, primary film coating is conducted, specifically, the surface of the automobile is coated with an anti-corrosion coating, and then drying of the anti-corrosion coating is accelerated through flowing hot air from bottom to top; and S5, primary surface treatment: after the anticorrosive paint is completely dried, water milling polishing treatment is performed, and the step S2 is repeated after treatment is completed. According to the automobile surface corrosion-resistant coating treatment method, flowing high-pressure steam is used for flushing the automobile surface for 2-3 times, oil stains and dust possibly attached to the surface can be removed, and the oil stains and the dust are prevented from affecting the adhesive force of a coating.

    本发明公开了一种汽车表面耐蚀耐腐涂膜处理方法,包括以下步骤:S1、抛光:对汽车表面进行打磨抛光处理;S2、清理:利用流动高压蒸汽对汽车表面冲洗2‑3次,再用无尘高压气流冲刷汽车表面2‑3次,冲洗/刷顺序均为从上到下;S3、电泳镀层:在汽车的表面涂层电泳漆,形成电泳层;S4、一次覆膜:先在汽车表面涂覆防腐涂料,再利用从下向上的流动热空气加速防腐涂料干燥;S5、表面一次处理:防腐涂料完全干燥后,进行水磨抛光处理,处理完毕后重复S2步骤。该汽车表面耐蚀耐腐涂膜处理方法,通过利用流动高压蒸汽对汽车表面冲洗2‑3次,可以去除表面可能沾染的油渍和灰尘,防止这些油渍和灰尘影响涂层的附着力。
