摘要
考察了酚型、胺型以及二烷基二硫代氨基甲酸酯 3种抗氧剂对低芥酸菜籽油摩擦学性能的影响 ,并通过对摩擦过程中基础油碘值和酸值变化的测定以及钢球磨损表面的反射红外光谱分析 ,探讨了菜籽油作为润滑剂基础油的摩擦化学作用机理 .结果表明 :抗氧剂使基础油的摩擦学性能变差 。
The effect of antioxidants, including phenol, amine and dithiodialkylcarbamate, on the tribological behavior of low erucic acid rapeseed oil was examined with a four ball machine and an infrared spectrometer. The variation in the iodine values and acid values of the lubricants during the friction process was monitored as well. As the results, all the antioxidants tested show adverse effect on the tribological behavior of the base stock. The tribological behavior of the rapeseed oil containing various antioxidants is related to the chemisorption and chemical reaction on the steel ball surface, which determines the properties of the boundary film on the steel surface.
