摘要
主要针对乙烯-丙烯共聚物(OCP)及异戊二烯共聚物(HSD)两大类7种粘度指数改进剂进行了性能考察,得出结论:Shell 260(氢化聚异戊二烯)这类星状聚合物结构合理,兼有优良的剪切稳定性及稠化能力,适合在有剪切稳定性要求的油品中使用,特别是对于调配大跨度的高档润滑油更加重要。
A performance investigation is carried out based on 7 brands of viscosity index modifiers belong to 2 categories, namely ethylene - propylene copolymer and isoprene copolymer. The investigation concludes that polymers with a star like structure such as Shell 260 (hydrogenated polyisoprene)can offer both excellent shear stability and thickening ability, are suitable for the use in lube oil with shear stability requirement, and are very important ingredient in blending of super quality lube oil which can be applied in very wide ranges.
