Title:
NON-FIRE SPREAD GREASE COMPOSITION
Document Type and Number:
Japanese Patent JP2022030575
Kind Code:
A
Abstract:
To provide a grease composition having improved non-fire spread as compared with a conventional non-fire spread grease composition while maintaining load resistance of the conventional non-fire spread grease composition.SOLUTION: A non-fire spread grease composition comprises: a base oil with kinematic viscosity at 40°C of 300 mm2/s or more; an urea-based thickener; a sulfur-based load-bearing additive; and, based on total mass of the composition, at least one polyhydric alcohol selected from a group consisting of 0.2 to 10 mass% of glycerin, trimethylolethane, and trimethylolpropane. Concentration of a sulfur element contained in the composition is 0.59 to 2.70 mass% based on total mass of the composition, and the concentration of a phosphorus element contained in the composition is 100 ppm at the highest.SELECTED DRAWING: None
