High-Temperature Antioxidant Screening for Silicone Oil

Abstract:

In order to prevent silicone oils from suffering oxidative deterioration and prolong its service life at high-temperature, an effective way is adding an appropriate antioxidant package in the base oil. Antioxidants can not only inhibit oil oxidation that produces acidic substances but also prevent the viscosity of oil from increasing. In this work, 1,3-dioctyl-1,1,3,3-tetraphenyl-disiloxane (OPDS) was used as silicone base oil, and several commercially available antioxidants were screened. Data show that TNPP, phenyl sulfide, 2088, and KY01 were effective at 300 ^oC, which could be further used as candidates for the antioxidant formulations of silicone base oils used as high temperature lubricants or hydraulic oils.
