摘要：

Studying the mechanism of binder is important for improving the coating formation process of solid lubricants. Two-component polyurethane (PU), polyvinyl butyral (PVB), and styrene-butadiene styrene (SBS) copolymer were selected as binders for polytetrafluoroethylene (PTFE) solid lubricant. The influence of solid lubricant coating prepared with different binders on the stamping properties of 6061-T6 aluminum alloy was compared and analyzed using the cupping test. A lubrication model was developed based on the results. Due to the difference in the molecular structure of the binders, the prepared solid lubricants have different characteristics and affect the dispersion of lubricant coating and its performance. When the content of PTFE reaches 15 wt% and the coating thickness is 10 mu m, the anodic aluminum alloy sheet with PVB coating has the smallest punch force.
