摘要
用成焦板 (或成漆板 )试验法考察了基础油及粘度指数改进剂对润滑油高温清净性的影响。结果表明 ,基础油的粘度和粘度指数改进剂对油品的高温清净性有很大影响 ;粘度较大的基础油的高温清净性明显优于低粘度的基础油 ,在低粘度的基础油中加入一些重组分 ,可明显改善油品的高温清净性 ;而在油品中加入粘度指数改进剂会使油品的高温清净性变差 ,非分散型粘度指数改进剂的负面影响更大。
The effects of base oil and viscosity index improver on high temperature detergency of lube oils were studied by the test method of coke forming plate or paint forming plate. The test result showed that the viscosity of base oil had significant influence on high temperature detergency of engine oils, the higher the viscosity of the base oil, the better the high temperature detergency of the engine oil. The high temperature detergency of the engine oil was worse after adding the viscosity index improver, especially the high negative effect of adding non dispersive viscosity index improver.
