高档柴油机油添加剂和配方技术研究进展

RESEARCH PROGRESS OF HIGH-GRADE DIESEL ENGINE OIL ADDITIVES AND FORMULATION TECHNOLOGY

环保和节能的要求促进了柴油机油质量标准升级,API CH-4及其以上规格高档柴油机油在多项性能上有较大提升。综述了近年来高档柴油机油添加剂和配方技术的研究进展,分析了为满足油品烟炱分散性、抗磨性、抗氧性和尾气后处理装置相容性等专项性能而采取的技术改进路线及其发展趋势。结果表明,高档柴油机油添加剂和配方技术的发展主要体现在新型结构添加剂单剂的开发、添加剂间配伍和协同作用的优化、润滑油稠化基础油配方优化等方面。在此基础上,对国产高档柴油机油产品的研发提出了一些指导性建议。

The quality standard of diesel engine oil has been upgraded due to the requirement of environmental protection and energy conservation.The quality of API CH-4 and above high-grade diesel engine oils has been greatly improved in many aspects.The progress of high grade diesel engine oil additives and formulation technology in recent years was reviewed.The technical improvement routes and its development trend to meet the specific performance of oil soot dispersion,wear resistance,anti-oxidative performance and exhaust after-treatment compatibility of diesel engine oil were investigated.The analysis results showed that the development of additives and formulation technology for high-grade diesel engine oil was mainly embodied in the development of new structural additives,the optimization of compatibility and synergy among additives,and the optimization of formulation for thickened base oil of lubricating oil.On this basis,some guiding suggestions were put forward for the research and development of domestic high-grade diesel engine oil products.
