A Summary of Development Situation of Anti-wear Extreme Pressure Additives without Sulfur, Phosphorus and Chlorine

Based on the requests of modern industry and society for lubricating oils, the research situation and tendency of anti- wear extreme pressure additives without sulfur, phosphorus and chlorine are briefly reviewed. The results show that anti- wear extreme pressure additives not containing active elements have good extreme pressure and anti- wear proper- ties, and they can meet the applicable requirements of modern machinery, equipment and increasingly harsh environment. Some preparation methods are compared and summarized. And anti -wear extreme pressure mechanism of these lubricant additives is analyzed emphatically. Its good development prospect is described.
