Synthesis and Performance Evaluation of Pour Point Depressants for Lubricating Oil

Abstract:

The paper describes synthesis and evaluation of polymeric additives for improving the flow properties of lubricating oils. The polymer (AAV) was prepared by the free-radical initiated polymerization of methacryl esters (A₁₄) with acrylamide and vinyl acetate. A₁₄ and AAV were characterized by infrared spectroscopy (IR). Three lubricating oils were selected as the test oil samples and the effect of solidification point depressant (ΔSP) with different mass fractions and other physicochemical characteristics of the samples with and without AAV added were investigated. In order to analyze the effect of AAV on the viscosity of lubricating oils, viscosity-temperature curves were plotted. The results showed that AAV not only had a good effect on dropping solidifying point for Yanshan lubricating oils, but also had a good effect on dropping viscosity; what’s more, other physicochemical characteristics of lubricating oil have little changes before and after AAV added.
