摘　　要：对KN盾尾密封油脂的研制过程、性能检测、性能指标及现场应用进行介绍。根据盾尾密封油脂的使用环境,通过工作原理分析,筛选出优质原材料,再通过六因素、五水平正交试验,得到基础油、润滑剂、增粘剂、增强剂以及粉料的最佳配比,制得KN型盾尾密封油脂,对盾尾密封油脂的实验室性能表征进行测试,得出详细的性能指标。通过在过河地层的盾构项目使用,满足使用要求。The development process, performance testing, performance indexes and field application of KN shield tail sealing grease are introduced. According to the use of the shield tail sealing grease environment, through the working principle analysis, high-quality raw materials were selected, and then based on the six factors and five levels orthogonal experiment, the base grease, lubricant, tackifier, strengthening agent, and the best proportion of powder, KN type shield tail sealing grease was developed, and the detailed performance indicators were obtained by testing laboratory performance characterization. The application performance data of this grease in the shield project crossing river stratum meets the operation requirement.
