摘要

在本研究中，我们开发了有机胺插层磷酸镁作为新型润滑剂。采用混合溶剂热合成方法首次制备了长链有机胺插层磷酸镁，即十二烷基胺插层磷酸镁（MgP-12N）、十八烷基胺插层磷酸镁（MgP-18N）和1,12-十二烷基二胺插层磷酸镁（mgp - 1,12n2）。加入润滑油后，这些样品具有良好的抗摩擦、抗磨性能和极压性能。根据Optimol SRV-V振荡往复试验机的评估，在N4010基础油中添加1.0 wt % mfp - 18n可显着将压力载荷值从400 N（基础油）提高到1400 N。此外，该样品在高工作载荷下具有低摩擦系数（0.107）和体积磨损（2.86 × 10-4 mm3）。摩擦表面的微观分析证实，在摩擦过程中，磨损表面形成了主要由胺插层磷酸镁组成的润滑膜。此外，在分散剂油胺的作用下，胺插层磷酸镁样品可以在润滑油中长时间分散，表明这些材料作为润滑材料具有广阔的应用前景。

Strategies for High-Value Utilization of Magnesium Resources from Salt Lakes: Synthesis of Amine-Intercalated Magnesium Phosphates as Innovative Lubricants.

In the present study, we developed organic amine-intercalated magnesium phosphates as new types of lubricants. Long-chain organic amine-intercalated magnesium phosphates, i.e., dodecylamine intercalated magnesium phosphate (MgP-12N), octadecylamine intercalated magnesium phosphate (MgP-18N), and 1,12-dodecanediamine intercalated magnesium phosphate (MgP-1,12N2), were prepared for the first time by mixed solvothermal synthesis. When added to lubricating oil, these samples exhibited good antifriction and antiwear properties and extreme pressure performance. Adding 1.0 wt % MgP-18N to N4010 base oil significantly increased the pressure load value according to evaluations using an Optimol SRV-V oscillating reciprocating tester from 400 N (base oil) to 1400 N. In addition, this sample exhibited a low friction coefficient (0.107) and volume wear (2.86 × 10-4 mm3) under high operating loads. Microscopic analysis of the rubbing surfaces confirmed that lubricating films mainly composed of amine-intercalated magnesium phosphates formed on the worn surface during the friction process. Moreover, the amine-intercalated magnesium phosphate samples could be dispersed in the lubricating oil for a long time under the action of the dispersant oleylamine, indicating that these materials have broad application prospects as lubrications.
