在蓖麻油(CO)中引入硼、氮,合成了新型润滑油添加剂——硼氮型改性蓖麻油添加剂,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:硼氮型改性蓖麻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蓖麻油分子的载体作用、硼的缺电子、氮的反应活性以及三者的协同作用在摩擦金属表面形成了一层高强度的吸附膜和/或磨擦化学反应膜。
Boron and nitrogen were introduced into castor oil (CO) to synthesize a new additive of boron-nitrogen modified castor oil, and its main functional groups were identified by infrared spectroscopy. The anti-wear and extreme pressure properties of rapeseed oil in rapeseed oil and water were investigated by four-ball machine. The results showed that boron-nitrogen modified castor oil additive has obvious anti-friction, anti-wear and extreme pressure properties. The lubrication mechanism is due to the long-chain castor oil molecular carrier effect, boron electron deficiencies, nitrogen reactivity and the synergy of the three formed in the friction metal surface layer of high-strength adsorption film and / or tribochemical reaction film .
