摘　　要：聚脲润滑脂属于性能较为全面的高温润滑脂,具有良好的氧化安定性、热稳定性、泵送性、机械安定性、胶体安定性、抗水性等优良性能,性能十分全面。综述近年来国内外聚脲润滑脂的研究进展,讨论基础油、稠化剂、添加剂对聚脲润滑脂的滴点、锥入度、分油率、极压抗磨性等性能的影响,并结合聚脲润滑脂发展趋势提出如下研发建议:聚脲润滑脂的基础油仍将以矿物油为主,但聚烯烃、酯类油等用量及占比会上升,废润滑油再生后得到的基础油也可用作润滑脂的制备,可降解基础油的研发应是未来重要方向之一;应加强构效关系研究,从而精准设计出可与基础油、添加剂匹配良好的稠化剂分子,进而实现聚脲润滑脂综合性能的调控;应根据聚脲润滑脂的个性化特点,加大新型添加剂的研发力度;应加强复合聚脲金属基润滑脂的研发力度,赋予聚脲润滑脂更为优异的性能。Polyurea grease is a kind of high temperature grease with all-round properties,such as excellent oxidation stability,thermal stability,pumping property,mechanical stability,colloid stability and water resistance.The research progress of polyurea grease at home and abroad in recent years was reviewed and summarized.The effects of base oil,thickener and additives on the properties of polyurea grease such as drop point,penetration,oil separation,extreme pressure and wear resistance,were discussed.Combined with the development trend of polyurea grease,the research and development suggestions were proposed as follows.The base oil will still be dominated by mineral oil,but the consumption and proportion of polyolefin,ester oil etc.will rise.The base oil obtained from the regeneration of waste lubricating oil can also be used for the preparation of lubricating grease,and the research and development of degradable base oil should be one of the important directions in the future.The study of structure-activity relationship should be strengthened,so as to achieve the accurate design of thickener molecules that can match well with base oil and additives,thereby achieving the regulation of the comprehensive performance of polyurea.The research and development of new additives should be strengthened according to the personalized characteristics of polyurea grease.The research and development of compound polyurea metal base grease should be strengthened to give polyurea grease more excellent performance.
