中文摘要:
      目的 改善甘油作为润滑剂的摩擦学性能。方法 合成一种含脲基新型无卤素的功能化咪唑离子液体(M-16-DOSS)并作为甘油的润滑添加剂。通过核磁共振和高分辨四级杆飞行时间质谱对M-16-DOSS的结构进行表征。采用同步热分析仪测试甘油润滑体系的热稳定性。采用SRV-IV微动摩擦磨损试验机评价了甘油润滑体系的摩擦磨损性能,通过三维轮廓仪对磨损体积和磨斑形貌进行了表征。采用EDS和XPS分析了磨斑表面元素和元素化学形态。结果 合成的功能化咪唑盐离子液体结构正确、纯度合格。M-16-DOSS与甘油具有良好的相容性且能够提高甘油的热稳定性。M-16-DOSS作为甘油的润滑添加剂可显著改善甘油的摩擦学性能,添加量达到1.5%时,摩擦系数下降到0.1,磨损体积下降80%。结论 在摩擦过程中发生了摩擦化学反应,通过硫氮的协同作用与铁和氧等元素形成了化学反应保护膜,有效地阻止了摩擦副之间的直接接触和碰撞,提高了甘油的减摩抗磨性能。
英文摘要:
      The work aims to improve the tribological properties of glycerin as a lubricant. A novel halogen-free functionalized imidazole ionic liquid (M-16-DOSS) was prepared as a lubricant additive for glycerin. The structure of M-16-DOSS was characterized by nuclear magnetic resonance and high-resolution quadrupole time-of-flight mass spectrometry; the thermal stability of the glycerin lubrication system was tested by a synchronous thermal analyzer; the friction and wear performance of the glycerin lubcaition system were evaluated by the SRV-IV micro-friction and wear tester and the wear volume and wear spot morphology were characterized by three-dimensional profilometer; and the surface elements and chemical morphology of wear spots were analyzed by EDS and XPS. The synthesized functionalized imidazole salt ionic liquid had the correct structure and qualified purity. M-16-DOSS had good compatibility with glycerin and could improve the thermal stability of glycerin. As a lubricant additive of glycerin, M-16-DOSS could significantly improve the tribological properties of glycerin. When the amount of M-16-DOSS was 1.5wt%, the friction coefficient decreased to 0.1 and the wear volume decreased by 80%. A tribochemical reaction occurs during the friction process. A chemical reaction protective film is formed with iron and oxygen through the synergistic effect of sulfur and nitrogen, which effectively buffers the direct contact and collision between friction pairs, and improves the anti-friction andante-wear performance of glycerin. This new type of functionalized imidazole ionic liquid has excellent properties and provides new ideas and options for the development of glycerin lubricant additives.
