| 摘 要： | 研究了蓖麻油轻度硫化（加0．5％S、1％S，2％S和3％S）对其流变性能、低温性能、热氧化安定性及生物降解性的影响。结果表明：轻度硫化蓖麻油的粘度增加，粘度指数减小，倾点上升，碘值减小，硫含量增加。表明不饱和程度在减小；随着硫化的增加，抗磨作用加强；轻度硫化蓖麻油的热氧化安定性大大增加。但生物降解率随基础油硫含量增加而减小。

| Abstract: | The influence of light sulfurized castor oil(adding 0.5%S,1%S,2%S,3%S) on the tribological and rheological characteristics,biodegradability,and thermal oxidation stability was studied.The results show that the viscosity of light sulfurized castor oil is increased and VI is decreased;the pour point is raised,but the unsaturated degree and iodine number is decreased;with the increase of sulfur content,tribological characteristic and oxidation stability are improved,but biodegradability is decreased. |
