Film-coating process for repairing automobile lamp

Abstract

The invention provides a film-coating process for repairing an automobile lamp, and relates to the technical field of automobile beauty care. For scratches on the surface of a lamp, the repair process flow comprises the following steps: disassembling; grinding the scratches; cleaning; film-coating and spraying; assembling the lamp; and delivering. For lamp damages such as yellowing and crazing, the repair process flow comprise the following steps of: disassembling; washing; surface grinding; cleaning; film-coating and spraying; polishing; secondarily film-coating and spraying; assembling the lamp; and delivering. The repair film-coating process is mainly used for repairing damage such as scratches, yellowing, crazing, surface blur and the like on lamps such as automobile lamps, tail lamps, instrument panels, alarm lamps and the like which are made from polymethyl methacrylate (PMMA), PBT (polybutylene terephthalate), PA (polyamide) and PC (polycarbonate) plastics and organic glass; and the original transparency and definition of the surface can be recovered quickly and effectively after repair and film coating, and after being repaired, the surface can achieve high hardness up to 4H, good oil resistance and high temperature resistance up to over 150 DEG C.

Description

Technical field: [0001] The invention relates to the technical field of automobile beauty care, in particular to an automobile headlight repair coating process. Background technique: [0002] Many car owners have such troubles. The beautiful car lights are inadvertently damaged, which casts a shadow on the eyes of the car. There are generally two types of headlight damage: [0003] The first one is that on the current crowded road, it is difficult to avoid the problem of scratching and bumping when driving, and it is also common to cause scratches on the surface of the car lamp.

Problems solved by technology

Therefore, while the car owner is annoyed, the insurance company's claims adjusters are also annoyed

[0004] The second type is that in daily use, the surface of the car light is often attacked by automobile exhaust, damaged by the sun's ultraviolet rays, corroded by daily chemicals, or the surface of the car light is blurred due to the high temperature of the light intensifier installed inside the car light. Yellowing, cracking, etc.

This method is a temporary solution, not the root cause, because there is a protective film on the surface of the lamp. Although the surface uses technology to deal with scratches and other problems, and then polishes the machine to brighten it, the brightness will come out after the process is completed, but the surface of the lamp is not. If the protective film is removed, after a short time, it is likely to cause secondary yellowing or even cracking of the lamp surface
