Embodiment 1

[0030] A coating process for automobile headlights, comprising the following steps:

[0031] (1) Surface cleaning: put the workpiece to be processed into a plasma cleaning machine, and clean the surface for 8 minutes under a vacuum of 100Pa;

[0032] (2) Surface treatment of PP vacuum plating treatment agent: Spray a layer of vacuum plating PP treatment agent with a thickness of 1.0-1.2mm on the workpiece after surface cleaning, and place it in a baking oven at a temperature of 65°C Bake for 5 minutes, and then use a fine grinding wheel to grind the surface until the thickness of the vacuum-coated PP treatment agent layer is 0.6mm, and the surface roughness is between Ra 0.1-Ra 0.2;

[0033] (3) Electrostatic dust removal: put the polished workpiece into a vacuum box under vacuum conditions, and use the internal electrostatic precipitator to perform electrostatic dust removal on the polished surface for 40 minutes;

[0034] (4) Spray UV primer: spray UV primer on the surface ...

Embodiment 2

[0039] A coating process for automobile headlights, comprising the following steps:

[0040] (1) Surface cleaning: put the workpiece to be processed into a plasma cleaning machine, and clean the surface for 6 minutes under a vacuum of 110Pa;

[0041] (2) Surface treatment of PP vacuum plating treatment agent: Spray a layer of vacuum plating PP treatment agent with a thickness of 1.0-1.2mm on the workpiece after surface cleaning, and place it in a baking oven at a temperature of 75°C Bake for 5 minutes, and then use a fine grinding wheel to grind the surface until the thickness of the vacuum-coated PP treatment agent layer is 0.7mm, and the surface roughness is between Ra 0.1-Ra 0.2;

[0042] (3) Electrostatic dust removal: put the polished workpiece into a vacuum box under vacuum conditions, and use the internal electrostatic precipitator to perform electrostatic dust removal on the polished surface for 45 minutes;

[0043] (4) Spray UV primer: spray UV primer on the surface ...

Embodiment 3

[0048] A coating process for automobile headlights, comprising the following steps:

[0049] (1) Surface cleaning: put the workpiece to be processed into a plasma cleaning machine, and clean the surface for 5 minutes under a vacuum of 110Pa;

[0050] (2) Surface treatment of PP vacuum plating treatment agent: Spray a layer of vacuum plating PP treatment agent with a thickness of 1.0-1.2mm on the workpiece after surface cleaning, and place it in a baking oven at a temperature of 60°C Bake for 5 minutes, and then use a fine grinding wheel to grind the surface until the thickness of the vacuum-coated PP treatment agent layer is 0.5mm, and the surface roughness is between Ra 0.1-Ra 0.2;

[0051] (3) Electrostatic dust removal: put the polished workpiece into a vacuum box under vacuum conditions, and use the internal electrostatic precipitator to perform electrostatic dust removal on the polished surface for 35 minutes;

[0052] (4) Spray UV primer: spray UV primer on the surface ...

Abstract

The invention belongs to the technical field of automobile lamp surface treatment, and particularly discloses an automobile lamp coating process. The automobile lamp coating process mainly comprises the following main seven steps of carrying out surface cleaning, carrying out PP vacuum plating treatment agent surface treatment, carrying out electrostatic dust removal, carrying out UV primer spraying, carrying out aluminum film coating, carrying out secondary protective film plating and carrying out UV finish paint spraying. According to the coating process, a PP vacuum plating treatment agentis taken as the middle layer, so that the adhesive force of an aluminum plating layer is greatly improved, meanwhile, plating of a protective film is carried out on the outer surface of the aluminum plating layer twice, and UV finish paint is sprayed so that the outer surface of the outer surface of the aluminized layer can be effectively protected, and the service life of a lamp is prolonged on the premise that the reflectivity of the vehicle lamp is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of automobile lamps, and in particular relates to a coating process for automobile lamps. Background technique [0002] The surface coating of car lights is one of the most important links in the manufacturing process of car lights. The performance of the reflective film of the condenser mirror of the main lamp of the exterior lighting of the automobile directly reflects the performance of the lamp, which affects the lighting effect of the vehicle and the safety of driving. There are various problems in the existing automobile lamps, among which there are various problems in the quality of the coating layer of the automobile lamps. For example, the uneven thickness of the coating layer of the car lamp leads to poor reflection effect, and the poor adhesion between the coating layer and the lamp body does not meet the requirements. [0003] The invention with the patent number CN10810346...
