摘要: 通过分子结构设计,将甲基咪唑引入氯化石蜡(CP)分子链中,合成氯化石蜡基支载型离子液体(CP-mimCl),并通过与基础油复配应用于极压抗磨领域。结果表明,热稳定性方面,最大分解温度CP-mimCl提高24 ℃,最大分解速率降低3.2%/min,并且表现出分解速率较低的特点;极压抗磨性能方面,不同载荷下CP-mimCl复合混合液的平均磨斑直径较CP复合混合液降低6.8%、7.7%、7.3%,摩擦系数降低36.2%,平均pB值增大15.7%;SEM结果表明,CP-mimCl复合混合液的磨斑形貌较CP复合混合液更为致密和细腻。Abstract: Methylimidazole was grafted onto the molecular chain of chlorinated paraffin (CP) to synthesize chlorinated paraffin-based supported ionic liquids (CP-mimCl) through molecular structural design, which was used in extreme pressure and antiwear field by compounding with base oil. The experiment results showed that the maximum decomposition temperature of CP-mimCl increased by 24 ℃, the maximum decomposition rate decreased by 3.2%/min, and also showed the characteristics of uniform weightlessness. Compared with CP composite solution, the average wear spot diameter of CP-mimCl composite solution decreased by 6.8%, 7.7%, 7.3% under different loads, friction coefficient decreased by 36.2%, and the average pB increased by 15.7%. The results of SEM showed that the wear spot morphology by CP-mimCl composite solution was more dense and delicate than that by CP composite solution.
