Spraying process of high-adhesion and rust-proof composite

Abstract

The invention discloses a spraying process of a high-adhesion and rust-proof composite. The spraying process of the high-adhesion and rust-proof composite comprises the following steps: S1, removing floated rust on rusted angle steel of the surface of an automotive bumper via an iron brush, evenly coating and brushing a phosphating solution, drying, cooling to room temperature, grinding, then carrying out flame treatment, and then carrying out electrostatic dust collection; S2, spraying primer paint, roasting and then cooling to the room temperature; S3, spraying intermediate paint to the bumper sprayed by the primer paint, curing and then cooling to the room temperature; S4, spraying finish paint to the bumper sprayed by the intermediate paint, curing and then cooling to the room temperature; and S5, spraying varnish to the bumper sprayed by the finish paint, roasting and cooling to the room temperature to obtain a finished automatic bumper sprayed by the paint. The paint on the surface of the automatic bumper processed by the paint spraying process is even and smooth, and is high in gloss, difficult to remove and excellent in corrosion resistance and rust resistance.

Description

technical field [0001] The invention relates to the field of painting techniques, in particular to a spraying technique of a high-adhesion antirust composite material. Background technique [0002] With the improvement of living standards in our country, as one of the main means of transportation for people nowadays, cars are increasingly entering the families of ordinary people. At present, the painting process of domestic car bumpers is not perfect, but cars will inevitably suffer to the infringement of silt and rainwater, and then silt and rainwater are mostly acidic substances, which have strong corrosion performance on the bumper of the car, which will cause the surface of the bumper to rust for a long time, affecting the appearance of the car and the service life of the bumper. To meet the needs in the actual use process, it is urgent to develop a spraying process of a high-adhesion anti-rust composite material to solve the problems in the prior art. Contents of the ...
