Abstract
The invention discloses an automobile roll line repairing method. The automobile roll line repairing method comprises the following steps that (a), the surface of an automobile body roll line position is grinded, the grinded position is cleaned by using a misty water flow in the grinding process, then deionized water and an organic solvent are adopted to conduct cleaning treatment on the surface of an automobile body, so that the surface of the automobile body is smooth, clean, dust-free, rust-free and grease-free; (b), drying treatment is conducted on the material cleaned in the step (a) for 20-30 minutes, and then flame treatment or corona discharge active group surface treatment is conducted on a roll line to strengthen the adsorption capacity of the roll line surface; (c), low-air-pressure roll-coating transparent paint is adopted for the roll line obtained after active treatment, the automobile body roll line is repaired, and drying is performed after roll coating is repeated three times; (d), roll line liquid is sprayed to a dried new and old paint film connection position for the first time, and then multiple times of roll line liquid spraying is performed after 50-70 seconds till new and old paint films are consistent in appearance. The mechanical property of an automobile body surface coating is effectively improved by adopting the automobile roll line repairing method.
Description
Technical field
The present invention relates to automotive field, specifically a kind of automobile roll line method for repairing and mending.
Background technology
The spray gun that existing conventional vehicle lacquer painting roller coating is used is to carry out roller coating operation using hyperbar, and air pressure is typically in 2.8-
3.5 bar air pressure.Under hyperbar big flow, a large amount of bounce-back of paint, a large amount of atomizations of paint have a strong impact on the strong of environment and workman
Health, whole process paint utilization rate there was only 35%-45%, material cost is too high, and during roller coating dust easily with gas
Stream is flushed to lacquer painting, has influence on the repairing effect of car body lacquer painting.
The content of the invention
A kind of automobile roll line method for repairing and mending, it is characterised in that comprise the following steps：
A. surface at car body roll line is polished, and in bruting process burnishing part is carried out clearly using fine mist current
Wash, then process be cleaned to car body surface using deionized water and organic solvent, make car body surface it is smooth, clean dustless,
Rustless, without grease；
B. the material that a step cleaning treatments are crossed is dried 20-30min of process roll line is carried out again flame treatment or
The surface treatment of the active group of corona discharge, to strengthen roll line adsorption ability；
C. the roll line after processing activity adopts low pressure roller coating celluloid paint, and car body roll line is repaired, and repeats to roll
Dried after Tu Sanci；
D. in prime paint surface roller coating floating coat paint, the floating coat paint is aliphatic polyurethane glass flake paint, is dried
Continuously three times polyurethane coating varnishes of roller coating are painted after 0.5-1.5 hours in floating coat.
Further, the coating layer thickness of the celluloid paint is 130 μm -150 μm.
The beneficial effects of the present invention is：The method can significantly improve the mechanical performance and glossiness of coating, make at roll line
Paint film is repaired consistent.
Specific embodiment
With reference to specific embodiment, the present invention will be further described.
A kind of automobile roll line method for repairing and mending, it is characterised in that comprise the following steps：
A. surface at car body roll line is polished, and in bruting process burnishing part is carried out clearly using fine mist current
Wash, then process be cleaned to car body surface using deionized water and organic solvent, make car body surface it is smooth, clean dustless,
Rustless, without grease；
B. the material that a step cleaning treatments are crossed is dried 20-30min of process roll line is carried out again flame treatment or
The surface treatment of the active group of corona discharge, to strengthen roll line adsorption ability；
C. the roll line after processing activity adopts low pressure roller coating celluloid paint, and car body roll line is repaired, and repeats to roll
Dried after Tu Sanci；
D. roll line liquid is sprayed for the first time to the new and old paint film interface position of coating after drying, after 50～70 seconds, then the
Roll line liquid is repeatedly sprayed, until new and old paint film appearance is consistent.
The coating layer thickness of the celluloid paint is 130 μm -150 μm.
The method can significantly improve the mechanical performance and glossiness of coating, make paint film at roll line repair consistent.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is 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.
Claims (2)
