AI Technical Summary

Technical Problem

The existing aluminum rod surface treatment technology has problems of low adhesion and poor corrosion resistance, especially the hard-to-be-treated metal workpieces in complex shapes, and the chemical surface treatment efficiency is low, resulting in poor coating quality.

Method used

Using a surface treatment agent, including 30% sulfuric acid solution, isomer alcohol oleate soap, triethanolamine borate and surfactant, through pickling and etching treatment, a uniform rough layer is formed, which enhances the adhesion of the metal surface and improves coating. Installation quality.

Benefits of technology

It significantly improves the adhesion and coating quality of metal surfaces, enhances the corrosion resistance of aluminum rods, simplifies the treatment process, avoids the difficulty of polishing, and improves the corrosion resistance of the workpiece.

Abstract

The invention discloses a surface treatment agent, an aluminum rod treatment method and application. The treatment agent comprises, by weight, 3-8 parts of a 30% sulfuric acid solution, 0.2-0.5 parts of isomeric alcohol oleic acid soap, 0.1-0.3 parts of triethanolamine borate and 0.1-0.5 parts of a surfactant. The surface treatment agent can deeply clean the grease on the surface, and significantly improve the surface bite degree and the uniformity of the roughness of the bite surface through the pickling action combined with a slow-release agent, thereby improving the adhesion of the metal surface during the coating process and improving the coating quality.
