Document Type and Number:
WIPO Patent Application WO/2022/211119
Kind Code:
A1
Abstract:
Provided is a grease composition containing: a base oil (A), a urea-based thickening agent (B), and melamine cyanurate (C). Particles including the urea-based thickening agent (B) in the grease composition satisfy requirement (I). The grease composition has superior wear resistance. Requirement (I): The area-based arithmetic average particle diameter of the particles is 2.0 μm or less as measured by a laser diffraction/scattering method. The particles including the urea-based thickening agent (B) in the grease composition preferably further satisfy requirement (II). Requirement (II): The specific surface area of the particles is 0.5×105 cm2/cm3 or more as measured by the laser diffraction/scattering method.
