硼氮型改性菜籽油润滑添加剂的制备及其摩擦学性能

The Synthesis and Tribological Behaviors of Boron - nitrogen Type Modified Rapeseed Oil as Additives for Lubricating Oil

在菜籽油（ＲＯ）中引入硼、氮，合成了新型润滑油添加剂—硼氮型改性菜籽油添加剂，并利用红外光谱对其主要官能团进行了鉴定。通过四球机考察了它在菜籽油和水中的抗磨性能与极压性能，结果表明：硼氮型改性菜籽油添加剂具有明显的减摩、抗磨和极压性能。其润滑作用机理是由于长链菜籽油分子的载体作用、硼的缺电子、氮的反应活性以及三者的协同作用与摩擦金属表面形成了一层高强度的吸附膜和／或摩擦化学反应膜。

A type of new lubricant additive, boron-nitrogen modified rapeseed oil, was synthesized and characterized by infrared spectrum. Their tribological properties in rapeseed oil and water wear tested on the four ball tester. The results show that the boron-nitrogen types of modified rapeseed oil as additives can Obviously increase the load-carrying capacity, antiwear and friction-reducing abilities of rapeseed oil, Its lubrication mechanism is infects that a high strength adsorption film and/or tribochemistry reaction film is formed on the rubbing surfaces due to the carrier effect of a long chain rapeseed oil, high reaction activity of nitrogen, electron-deficient of boron and their synergism.
