摘要
实验室考察了三种国产氢化苯乙烯-双烯共聚物黏度指数改进剂,发现每种国产氢化苯乙烯-双烯共聚物黏度指数改进剂的增稠能力,剪切安定性和低温性能均不如进口氢化苯乙烯-双烯共聚物黏度指数改进剂。但将其中的两种国产氢化苯乙烯-双烯共聚物黏度指数改进剂1∶1在CF-4 15W-40柴油机油中混合使用,18 Mm行车试验表明,国产氢化苯乙烯-双烯共聚物黏度指数改进剂的实际使用性能与进口氢化苯乙烯-双烯共聚物黏度指数改进剂相当。
Three domestic hydrogenated styrene-diene copolymer viscosity index improvers were investigated in laboratory, it was found that the thickening ability, shear stability and low temperature performance of every hy- drogenated styrene-diene copolymer viscosity index improver were inferior to those of imported hydrogenated styrene-diene copolymer viscosity index improver.Of which two domestic hydrogenated styrene-diene copolymer viscosity index improvers were mixed 1：1 to use in CF-4 15W-40 Diesel engine oil, 18 Mm road test showed that the practical application performance of domestic hydrogenated styrene-diene copolymer was equivalent to that of imported hydrogenated styrene-diene copolymer viscosity index improver.
