摘　　要：在复合钠皂稠化多烷基环戊烷中加入复合添加剂制备了一种低挥发润滑脂。对低挥发润滑脂的饱和蒸气压、真空质损、耐辐射、相容性等应用试验性能以及真空热循环台架试验进行了评价。结果表明:该润滑脂不仅具有良好的高低温性能、胶体安定性、氧化安定性、防腐蚀性、极压抗磨性,同时具有较低的饱和蒸气压(3.4×10^(-6) Pa)和挥发性(总损失率0.95%,可凝挥发物质量分数0.088%);极强的耐辐射性能(可耐受1×10~5 Gy剂量)以及与真空设备材质良好的相容性,并且通过了真空热循环台架试验。A kind of low-volatile grease was prepared by adding a variety of additives in composite sodium soap thickened polyalkylcyclopentane and evaluated its physical and chemical properties.A series of application tests such as the saturated vapor pressure,the vacuum mass loss,the radiation resistance,compatibility,and vacuum thermal cycling bench test were conducted.The result showed that the grease not only has good performance in high and low temperature,colloid stability,oxidation stability,corrosion resistance,extreme pressure and abrasion resistance,lower saturated vapor pressure（3.4×10^-6 Pa）,lower volatility（total loss rate of 0.95%,condensable volatile matter content of 0.088%）,strong radiation resistance（which can withstand 1×10^5 Gy dose）and good compatibility with the vacuum equipment material.The grease passed the vacuum thermal cycling bench test.
