Embodiment

[0026] Embodiment: a kind of automobile surface paint color registration spraying method of the present embodiment comprises the following steps:

[0027] (1). In the intermediate coating spray booth, the intermediate coating is applied by robot spraying;

[0028] (2). Flash dry, the temperature is the room temperature of the intermediate coating spray booth (generally 17-38 ℃), and the time is 90S;

[0029] (3). In the manual spray booth, the color paint is sprayed manually, with a thickness of 18 μm;

[0030] (4). Enter the drying room for drying, the temperature is 140 ° C, and the time is 20 minutes;

[0031] (5). Enter the strong cold room to force the body to cool down for 4 minutes;

[0032] (6). Enter the grinding room to grind and eliminate the defective parts of the body coating;

[0033] (7). Use masking paper and color separation tape to cover the colored paint part;

[0034] (8). Robots are used to spray the main color paint in the paint spray room;

Abstract

The invention relates to an automobile surface paint chromatic spraying method, which comprises the following steps of floating coat paint spraying, flash drying, chromatic paint spraying and coating, drying, forced cooling, grinding, shielding, main color paint spraying and coating, flash drying, shielding dismounting, finish varnish spraying and coating, finish paint drying, finish paint forced cooling and finishing polishing and grinding. A wet-to-wet process method is adopted between the floating coat paint and the chromatic paint, and the goals of simplifying the process, improving the efficiency, saving the energy consumption and reducing the cost are reached. Meanwhile, the drying work procedure is reduced, the excessive drying of automobile bodies is avoided, and the mechanical performance of a paint film of the chromatic automobile body is improved.

Description

technical field [0001] The invention relates to an automobile spraying method, in particular to an automobile surface paint color registration spraying method which reduces technological process, improves work efficiency and reduces production cost. Background technique [0002] With the individual requirements of customers and the needs of some special models (such as taxis), the demand for color-matching spraying for automotive surface paint is increasing, especially the market demand for color-matched cars and color-matched pickup trucks is increasing year by year. . The general process of the current color registration spraying process of automobile surface paint is: intermediate coating spraying→intermediate coating drying→intermediate coating strong cooling→intermediate coating grinding→spraying color registration paint→drying→strong cooling→grinding→masking→spraying main color paint→ Flash drying→removal of masking→spraying of varnish→drying of topcoat→strong cooling...
