摘要
选取3种常用的乙烯丙烯共聚物型粘度指数改进剂,考察其在高温条件下的增粘行为,分析了影响多级油粘温关系的因素,对生产高质量多级油以及筛选粘度指数改进剂具有重要的指导意义。
Three kinds of olefin copolymer(OCP)viscosity index improver were dissolved in 150SN mineral base oil,and the thickening performances in wide temperature range similar automotive operation conditions have been investigated.Factors affecting the viscosity-temperature relationship have been analysed,and the relavant predica- tion model has been regressed and related to the chemical structure of these viscosity index improvers.The present work will give light to production of premium mutigrade oils and selection of viscosity index improvers.
