摘要

为了满足循环经济的要求，我们以玉米芯提取物这种天然可再生的生物质材料为基础，开发出了一类不含硫和磷的绿色双功能润滑油添加剂。这些添加剂可显著增强基础油的减摩性、抗磨性和氧化稳定性。结果表明，当添加量为 4000 ppm 时，三元聚合物添加剂可将钢摩擦副的磨损量和表面粗糙度分别降低 98.17 % 和 97.63 %，并将氧化诱导期延长 40.52 %。摩擦学性能的改善归因于刚性环结构阻止了摩擦副之间的直接接触，以及羧酸和酸酐基团与金属的化学吸附，形成了致密的摩擦膜。

Evaluation of the tribological performance and oxidative stability of a bi-functional lubricating oil additive prepared from corn cob extract

To meet the requirements of a circular economy, a class of sulfur- and phosphorus-free green bifunctional lubricating oil additives was developed based on corn cob extract as a naturally renewable biomass material. These additives can significantly enhance the friction-reducing, anti-wear properties, and oxidative stability of base oils. Results indicate that at an addition level of 4000 ppm, ternary polymer additive reduced the wear volume and surface roughness of steel friction pairs by 98.17 % and 97.63 %, respectively, and increased the oxidation induction period by 40.52 %. The improvement in tribological performance is attributed to the rigid ring structure preventing direct contact between friction pairs, and the chemical adsorption of carboxylic acid and anhydride groups with the metal, forming a dense friction film.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
