Abstract
Official abstract text for this publication.
A lithium salt thickener that enhances thermal stability at high temperature and operability at low temperature, and a grease composition including the same, is provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A lithium-based thickener represented by Formula 1 below: wherein m and n are the same or different and are integers of 5 to 20. 2. The lithium-based thickener according to claim 1 , wherein m and n are the same or different and are integers of 7 or 8. 3. A grease composition comprising a synthetic polyalphaolefin (PAO) base oil, a lithium-based thickener and grease additives, wherein the lithium-based thickener is a 9,10,12-trisubstituted stearate lithium salt represented by Formula 1 below: wherein m and n are the same or different and are integers of 5 to 20. 4. The grease composition according to claim 3 , wherein the grease composition comprises: 70 to 85% by weight of the synthetic polyalphaolefin (PAO) base oil; 10 to 20% by weight of the lithium-based thickener; and 0.1 to 10% by weight of the additives. 5. The grease composition according to claim 3 , wherein an ester-based viscosity regulator having a viscosity of 500 to 1000 cSt is included as an additive. 6. The grease composition according to claim 5 , wherein the ester-based viscosity regulator is included in a content range of 1 to 7% by weight based on a total weight of the grease composition. 7. The grease composition according to claim 3 , wherein one or more styrene-based oil separation regulators selected from the group consisting of a styrene-ethylene/propylene block copolymer and a styrene-isoprene copolymer are included as additives. 8. The grease composition according to claim 6 , wherein the styrene-based oil separation regulator is included in a content range of 0.5 to 3% by weight based on a total weight of the grease composition.
