摘要/Abstract

摘要： 以五氧化二磷、烷基醇和聚异丁烯丁二酰亚胺为原料合成多功能齿轮油极压抗磨添加剂MEAD，利用红外分析确认添加剂的结构，考察MEAD在基础油中的溶解性以及防锈、抗腐蚀性能，通过烘箱氧化试验、四球和SRV摩擦磨损试验等评价MEAD的油泥分散性和摩擦学性能，并与其它常用极压抗磨剂进行对比。结果表明，合成的多功能齿轮油极压抗磨添加剂MEAD具有良好的防锈、油泥分散、承载、抗磨损及摩擦稳定性。

Abstract: A multifunctional extreme pressure antiwear additive (MEAD) for gear oil was synthesized using phosphorus pentoxide, alkyl alcohol and polyisobutene succimide as raw materials. The structure of the additive was determined by FT-IR, its oil solubility, anti-corrosive capability, sludge dispersion and tribology performance were tested by oven oxidation, four-ball and SRV tests, as well as compared with conventional extreme pressure antiwear additive. Test results indicate that MEAD additive holds excellent performance of antirust, sludge dispersion, load bearing, anti-wear and friction reducing stability.

Key words: multifunction, EP/AW additive, sludge dispersion, stability of friction
