High dropping-point lithium-complex grease having improved anti-noise properties

摘要

High dropping-point lithium-complex grease composition naving improved anti-noise properties, comprising a lubricating oil and the following components:(a) at least one lithium soap selected from the group consisting of the lithium salts of C₁₀ to C₃₄ fatty acids and C₁₂ to C₂₄ hydroxy fatty acids,(b) at least one lithium salt selected from the group consisting of the dilithium salts of C₄ to C₁₂ aliphatic dicarboxylic acids, the lithium salts of boric acids, and the lithium salts of aromatic hydroxy carboxylic acids, and(c) a high-molecular viscosity-index improver, and/or succinimide-type dispersant and/or metal salt detergent.
