纳米磁性润滑油的制备

Preparation of Nano-magnetic Lubricating Oil

以五羰基铁、聚丁烯基丁二酰亚胺四乙烯五胺表面活性剂、油基液和氨气为原料,利用自制的装置制备磁性润滑油。利用VSM、X射线小角散射和TEM分别对磁性润滑油的磁滞回线、纳米颗粒粒径大小、分布及形貌等进行表征。测试结果表明,磁性润滑油属超顺磁材料,磁饱和强度为0.025 9 T;其组成的颗粒具有纳米量级,在润滑油具有良好的分散稳定性。

The magnetic lubricating oil was prepared by self-made equipment using Fe（CO）5, potybutylene succinic imide IV pentamine surfactant, oil-based liquid and NH3 as raw materials. The hysteresis loop, particles size distribution of nanoparticles and morphology of the magnetic lubricating oil were characterized by VSM, X-ray small angle scattering and TEM. The test results show that the magnetic lubricating oil is ultra-paramagnetic material and its saturated magnetic intensity is 0. 025 9 T. The particle composition is nanometer scale,which has good stability in magnetic lubricating oil.
