NOVELTY - Lubricating grease composition with anti-radiation performance comprises base oil, thickener and optional additive. The base oil is a mixed oil of alkyl naphthalene and alkyl diphenyl ether in a mass ratio of 1:0.3-3. The additive is structural improver, antioxidant, rust inhibitor or extreme pressure agent. USE - Used as lubricating grease composition with anti-radiation performance. ADVANTAGE - The lubricating grease composition has anti-radiation performance, long service life, good radiation resistance, extreme pressure, oxidation resistance, corrosion resistance, anti-rust property, and capable of satisfy with a lubricating requirement of radiation working condition. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing grease composition comprising mixing part of base oil, water, acid, lithium precursor and structure improver for saponification reaction, heating and refining, mixing with remaining base oil and optional other additive, where the other additives are antioxidant, rust inhibitor or extreme pressure agent; and a grease composition.
