Abstract

The oleogel acts as a middle phase to improve the dispersion stability of magnesium silicate hydroxide (MSH) nanoparticles in PAO base oils and simultaneously enhance the tribological properties of oil samples. The oleogel is comprised of Sorbitan monostearate (Span60), MSH nanoparticles, and PAO oil which is used as the gelator, anti-wear phase, and the base stock, respectively. The prepared oleogel and PAO oil are mixed by stirring to achieve the dispersion of MSH nanoparticles in oil. Centrifugal experiments showed that dispersion stability of MSH nanoparticles can be greatly improved through the oleogel middle phase. Tribological tests also show that the oleogel can further enhance the anti-wear and friction reduction performance of the lubricating oil.

Using the oleogel as a middle phase, the dispersion stability and tribological properties of magnesium silicate hydroxide (MSH) nanoparticles in PAO base oils was greatly improved.

Span60油凝胶增强了氢氧化硅酸镁纳米粒子的分散性和摩擦学性能

摘要

油凝胶充当中间相，可改善氢氧化硅酸镁（MSH）纳米颗粒在PAO基础油中的分散稳定性，同时增强油样品的摩擦学性能。油凝胶由分别用作胶凝剂，抗磨相和基础油的单硬脂酸山梨糖醇酯（Span60），MSH纳米颗粒和PAO油组成。通过搅拌将制备的油凝胶和PAO油混合以实现MSH纳米颗粒在油中的分散。离心实验表明，通过油凝胶中间相可以大大提高MSH纳米颗粒的分散稳定性。摩擦学测试还表明，油凝胶可以进一步增强润滑油的抗磨损和降低摩擦性能。
