摘要 由于传统润滑油对环境的破坏作用,以及石油资源的逐渐减少,开发新型的、可生物降解的润滑油代替矿物润滑油具有重大的社会和经济意义。为了合理开发出可生物降解润滑油,以菜籽油为基础油,选用了硫系(T321和T322)与磷系(T307)添加剂为基础添加剂,研究了它们在菜籽油中的摩擦学性能。实验结果表明:与加入T322和T307相比,在菜籽油中加入添加剂T321和T307的平均最大无卡咬负荷值,与磨斑直径为1.0mm的载荷Pd1.0分别平均提高7.35%和19.53%,钢球在载荷为392N时,30min长磨时间的磨斑直径平均降低5.07%,因此,在菜籽油中加入T321和T307的抗磨性能和极压性能较好。 The traditional lubricating oil pollutes the environment,and the petroleum resource is reducing too,so it becomes very significant in both social and economic perspective to develop a new biodegradable lubricating oil to replace the mineral oil.In order to develop the biodegradable lubricants,the rapeseed oil is used for the base oil,with the Sulfur-system (T321 and T322) and Phosphorus-system (T307) additives,the tribological property is investigated.The experiment result shows that compared with rapeseed oil with T322 and T307,the rapeseed oil with T321 and T307 has,on average,an increase of 7.35% for the maximal non-seizer load,an increase of 19.53% for the load at the wear scar diameter of 1.0 mm,a reduction of 5.07% for the wear scar diameter under 392N for 30 min.So the anti-wear property and the extreme pressure of rapeseed oil with T321 and T307 is better than that with T322 and T307.
