Automobile accessory surface spraying process

Abstract

The invention discloses an automobile accessory surface spraying process. The automobile accessory surface spraying process comprises the following steps that firstly, a site is treated; 2, accessory surface treatment is conducted, wherein, the surfaces of automobile accessories are subjected to dust removal, oil stain removal, grinding and polishing and static electricity removal, meanwhile, the surfaces of the accessories are subjected to phosphating treatment, and the accessories are dried for standby application; 3, paint preparation is carried out, wherein paint is prepared according to the proportioning requirement, and uniformly mixed, the viscosity of the paint in a use state is measured, the paint is filtered to remove impurities in the paint, and the paint is prepared for later use; 4, spraying is carried out, wherein primer spraying, intermediate coat spraying and finishing coat spraying are conducted; and 5, acceptance is carried out, wherein whether sagging, sandy surface, orange peel, wrinkling, bleeding, fine lines, cracking, pinholes, bottom exposure and non-uniformity occur on the surfaces of the automobile accessories is checked, and packaging and warehousing are carried out on the automobile accessories after the automobile accessories are checked to be qualified. Compared with the prior art, the process has the advantages that the anti-corrosion performance is better, meanwhile, the defects such as peeling or cracking are not prone to occurring, and the quality of the automobile accessories is improved.

Description

technical field [0001] The invention relates to the technical field of spraying process for auto parts, in particular to a surface spraying process for auto parts. Background technique [0002] With the continuous progress and development of society, cars have become more popular and become the daily means of transportation for most people. Cars are composed of many accessories, and the quality of the surface treatment of accessories is directly related to the overall quality and quality of the car. At present, the surface spraying process of auto parts is relatively simple. Although the appearance looks relatively clean and beautiful, it is very good-looking, but after being collided with the outside world, its anti-corrosion performance is very poor, and some cars have been exposed to the sun for a long time. The paint surface sprayed on the outer surface of each accessory is easy to peel or crack, which greatly reduces the quality of auto accessories. Contents of the in...
