Abstract

The invention discloses a coating agent for aluminum alloy wheels of automobiles and a coating process. The coating agent is prepared from the following raw materials in parts by weight: 20-30 parts of low-temperature glass transition temperature acrylic resin, 0.3-0.5 parts of dispersant, 0.3-0.5 parts of Defoamer, 2-2.5 parts of aluminum powder, 10-12 parts of low heavy metal zinc phosphate, 40-50 parts of nitrocellulose solution, 1-2.0 parts of plasticizer, 30-40 parts of wax solution; Resin, dispersant, defoamer and 300-400mL solvent are added in the reaction kettle and stirred and mixed, the stirring speed is 1500r / min, and the stirring time is 5-10 minutes to obtain a mixture; the coating agent prepared by the present invention is very environmentally friendly and It has excellent corrosion resistance, water resistance and anti-ultraviolet function; and after the coating agent is applied to the surface of the hub by spraying equipment, it has excellent compactness and excellent protection effect.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hubs, in particular to an automotive aluminum alloy wheel hub coating agent and a coating process. Background technique [0002] At present, the rapid development of automobiles has also led to the rapid development of wheels. Aluminum alloy wheels have become mainstream wheel products due to their beautiful appearance, light weight, fast heat dissipation, and high roundness. Aluminum alloy wheels are mainly formed by die-casting, and the surface is rough. After machining, there are burrs, scratches and other defects on the surface that require surface treatment. The current surface treatment methods include painting, water electroplating, and vacuum coating. Among them, coating and water electroplating are widely used; [0003] In the existing coating process, coating agents are often used for coating, but the corrosion resistance, water resistance and UV protection of the existing coa...
