Abstract

The polyionic liquid poly-PEGMA-r-METAC (PPM) with quaternary ammonium has been synthesized and evaluated as additive in aqueous lubricating fluids. The rheological behavior of aqueous lubricating fluids with PPM has been characterized to confirm PPM’s function as a viscosity modifier. The tribological behavior of aqueous lubricating fluids with PPM has been investigated on SRV-V and MTM testing machines. It was found that PPM has excellent viscosity-increasing, lubricating, and anti-wear properties as an additive for aqueous, which can be attributed to the ability of PPM to form the protective film and boundary tribofilm generated from complex tribochemical reaction on rubbing surface. The obtained PPM with dual functions of anti-corrosion additives and viscosity index improver can play an important role in diverse lubrication regimes.

一种具有润滑增粘双重功能的新型聚离子液体作为水性润滑体系的添加剂

摘要

合成了含有季铵的聚离子液体聚 PEGMA-r-METAC (PPM)，并对其作为水性润滑液添加剂进行了评估。对含有 PPM 的水性润滑液的流变行为进行了表征，以证实 PPM 作为粘度调节剂的功能。已在 SRV-V 和 MTM 试验机上研究了含有 PPM 的水性润滑液的摩擦学行为。研究发现，PPM作为水性添加剂具有优异的增粘、润滑和抗磨性能，这归因于PPM能够在摩擦表面形成由复杂的摩擦化学反应产生的保护膜和边界摩擦膜。所获得的具有防腐添加剂和粘度指数改进剂双重功能的PPM可以在多种润滑方式中发挥重要作用。
