Automotive body repairing spraying process

Abstract

The invention provides an automotive body repairing spraying process and relates to the technical field of spraying processing. The automotive body repairing spraying process comprises the following steps that an area to be repaired is cleaned through detergent and then cleaned up through clear water, and then the surface of a part is cleaned through a finish paint diluent; the area to be repaired is polished to form a bevel opening, the upper portion of the bevel opening is high, and the lower portion of the bevel opening is low; putty powder is sprayed for leveling and is dried, then a tackifier is sprayed and dried, the thickness of the tackifier is made to be uniform through scraping by a rubber scraper, the polished area to be repaired is kept as a bevel all the time, and sanding and side finishing are carried out; the tackifier is sprayed to the polished area to be repaired again and is dried, then medium coating is sprayed for filling and leveling, the polished area to be repaired is kept as the bevel, and an original paint layer on an automotive body is polished completely; and paint and curing agents for the automotive body are diluted and mixed, are obliquely sprayed from the upper portion to the lower portion of the spraying bevel opening after being proportionally mixed, and then are dried. According to the automotive body repairing spraying process, the curing speed is high, the gravity effect is low, the flatness of the sprayed plane is high, and the repairing and restoring effects are good.

Description

technical field [0001] The invention relates to the technical field of spraying processing, in particular to an automobile body repairing spraying process. Background technique [0002] The powder car coating (mainly the coating of the car body) is also a high-grade decorative coating. It must be carefully designed and equipped with a good coating environment and conditions in order to make the coating have good decorative properties. The decoration of the car mainly depends on the painting, which depends on the quality of the painting and directly affects the commodity value of the car. In the surface spraying treatment of the car body in the prior art, some topcoats have a slow curing speed and are easy to peel off, and the area to be repaired is vertically polished. Often when spraying, it is difficult to keep the exterior smooth when spraying on the front, and because the curing speed of the paint is slow , often under the action of gravity, the thickness of the paint o...

Problems solved by technology

In the surface spraying treatment of the car body in the prior art, some topcoats have a slow curing speed and are easy to peel off, and the area to be repaired is vertically polished. Often when spraying, it is difficult to keep the exterior smooth when spraying on the front, and because the curing speed of the paint is slow , often under the action of gravity, the thickness of the lower part of the paint is relatively large, while the thickness of the upper part is smaller, which makes it difficult to achieve vertical flatness on the sprayed surface, and the effect of repair and restoration is poor
