Abstract
The invention discloses a method for repairing paint on the outer surfaces of automobiles. The method includes steps of a, polishing the surfaces of spliced openings of automobile bodies, cleaning polished positions by the aid of mist-shaped water flow in polishing procedures and cleaning the surfaces of the automobile bodies by the aid of deionized water and organic solvents to enable the surfaces of the automobile bodies to be smooth, clean, dust-free, rust-free and grease-free; b, spraying transparent paint by the aid of low air pressures, repairing the spliced openings of the automobile bodies, repeatedly spraying the transparent paint on the spliced openings thrice, then drying the spliced openings, spraying priming paint on the spliced openings to allow the roughness to reach 8-15 micrometers and drying the spliced openings for 30 minutes; c, spraying intermediate coating paint on priming paint surfaces, drying the priming paint surfaces for 0.5-1.5 hours and then continuously spraying polyurethane finish varnish on the intermediate coating paint thrice. The priming paint comprises white corundum sand grains. The intermediate coating paint is aliphatic polyurethane glass flake paint. The method has the advantage that the mechanical performance of coatings on the surfaces of the automobile bodies can be effectively improved.
Description
Technical field
The present invention relates to automotive field, specifically a kind of outer surface of automobile touch-up paint method.
Background technology
The spray gun that existing conventional vehicle lacquer painting spraying uses is to carry out spraying operation using hyperbar, and air pressure is typically in 2.8-
3.5 bar air pressure.Under hyperbar big flow, paint is a large amount of to rebound, and paint is a large amount of to be atomized, and has a strong impact on the strong of environment and workman
Health, whole process paint utilization rate only have 35%-45%, material cost is too high, and in spraying process dust easily with air-flow
It is flushed to lacquer painting, have influence on the repairing effect of car body lacquer painting.
Content of the invention
A kind of outer surface of automobile touch-up paint method is it is characterised in that comprise the following steps:
A. is polished in surface at car body roll line, and using fine mist current, burnishing part is carried out in bruting process, then
Using deionized water and organic solvent car body surface is cleaned process, make car body surface smooth, totally dustless, rustless,
Without grease；
B adopts low pressure to spray celluloid paint, car body roll line is repaired, is dried after repeating to spray three times；Spray again
Prime paint, priming paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；
C. in prime paint surface spraying floating coat paint, described floating coat paint is aliphatic polyurethane glass flake paint, and 0.5- is dried
1.5 continuous after hour paint three times polyurethane coating varnishes of spraying in floating coat.
Further, the coating layer thickness of described prime paint is 100 μm -120 μm.
Further, the coating layer thickness of described floating coat paint is 130 μm -150 μm.
Further, the coating layer thickness of described polyurethane coating varnish is 130 μm -150 μm.
The beneficial effects of the present invention is: the method can significantly improve the mechanical performance of coating and glossiness, thus improving
The wearability of coating, impact resistance and protect color gloss retention.
Specific embodiment
With reference to specific embodiment, the present invention will be further described.
A kind of outer surface of automobile touch-up paint method is it is characterised in that comprise the following steps:
A. is polished in surface at car body roll line, and using fine mist current, burnishing part is carried out in bruting process, then
Using deionized water and organic solvent car body surface is cleaned process, make car body surface smooth, totally dustless, rustless,
Without grease；
B adopts low pressure to spray celluloid paint, car body roll line is repaired, is dried after repeating to spray three times；Spray again
Prime paint, priming paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；
C. in prime paint surface spraying floating coat paint, described floating coat paint is aliphatic polyurethane glass flake paint, and 0.5- is dried
After 1.5 hours, continuous painting in floating coat sprays three times polyurethane coating varnishes.
The coating layer thickness of described prime paint is 100 μm -120 μm.The coating layer thickness of described floating coat paint is 130 μm of -150 μ
m.The coating layer thickness of described polyurethane coating varnish is 130 μm -150 μm.
The method can significantly improve the mechanical performance of coating and glossiness, thus improve the wearability of coating, shock resistance
Property and protect color gloss retention.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
