摘要：聚酰胺-酰亚胺树脂(PAI)具有优异的耐磨性能和粘结性能,以PAI为基体,添加固体润滑剂MoS2和聚四氟乙烯PTFE、BYK-163型分散剂、EFKA-3772型流平剂,制备了一种耐磨、耐蚀的PAI自润滑复合涂料。利用MRH-3G摩擦磨损试验机研究了不同固体润滑剂用量对涂层摩擦磨损性能的影响,采用金相显微镜和扫描电镜(SEM)观察涂层摩擦磨损前后的表面形貌。结果表明:当PAI自润滑复合涂料中MoS2含量为30%(质量分数)、PTFE含量为6%(质量分数)时,以其制备的PAI自润滑复合涂层致密性强,孔隙率少,耐腐蚀性强,摩擦磨损性能最佳,涂层其余理化性能也最佳。
Polyamide-imide (denoted as PAI) was adopted as the matrix to prepare PAI-based self-lubricating wear-resistant paint in the presence of solid lubricants of MoS2 and polytetrafluroethylene (PTFE) as well as BYK-163 type dispersant and EFKA-3772 type flatting agent. PAI-based self-lubricating wear-resistant composite coating was then prepared from as-obtained paint. The effect of solid lubricants on the wear resis-tance of as-prepared PAI-based composite coating was investigated with an MRH-3G friction and wear tester,and the morphology of the composite coating before and after friction and wear tests was observed with a scanning electron microscope. It was found that, when the contents of MoS2 and PTFE in as-obtained PAI-based self-lubricating wear-resistant paint were 30% (mass fraction; the same hereafter) and 6% respectively, corresponding PAI-based composite coating possessed desired compactness and small porosity as well as excellent corrosion resistance, wear resistance and physical-chemical properties.
