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.
