Development and application of viscosity index improver for shear-resistant and low-temperature lubricating oil
The viscosity index is an important index to measure the degree of oil viscosity change with temperature.The improver of lubricating oil viscosity index is mainly used to improve the viscosity and temperature performance of lubricating oil,that is,it can maintain a relatively stable viscosity at different temperatures.However,it is difficult for common improvers to have the characteristics of viscosity increase,shear resistance,low temperature effect and friction at the same time.Therefore,this paper aims to prepare a viscosity index improver with excellent viscosity increasing,low temperature resistance,shear resistance and wear resistance through experiments to meet all the above characteristics.
