Abstract
Official abstract text for this publication.
A lubricant composition is described. The novel lubricant composition has superior thermal stability, and can reduce the need to replenish the lubricant. The lubricant composition includes at least a soap component, a thickener component, an oil component, and a spherical polyolefin component (optionally Microthene). The spherical polyolefin component includes polyolefin microparticles.
First claim
Opening claim text (preview).
What is claimed is: 1. A lubricant composition comprising: 1-10 wt. %, based on the total weight of the lubricant composition, of a soap component, 1-6 wt. %, based on the total weight of the lubricant composition, of a thickener component, 74-97 wt. %, based on the total weight of the lubricant composition, of an oil component, and wherein the oil component comprises a spherical polyolefin component, wherein the spherical polyolefin component comprises microparticles and wherein the polyolefin microparticles are EVA (ethylene-vinyl acetate) copolymer particles. 2. The lubricant composition of claim 1 , wherein the polyolefin microparticles are spherical or substantially spherical in shape. 3. The lubricant composition of claim 2 , wherein the polyolefin particles have an average particle size of 1-100 μm. 4. The lubricant composition of claim 2 , wherein the polyolefin particles have an average particle size of 5-50 μm. 5. The lubricant composition of claim 1 , wherein the lubricant composition comprises about 1-10 wt % of the polyolefin microparticles. 6. The lubricant composition of claim 1 , wherein the soap component is stearate. 7. The lubricant composition of claim 6 , wherein the lubricant composition comprises about 2-9 wt. % of the soap. 8. The lubricant composition of claim 1 , wherein the thickener comprises graphite, tar or mica. 9. The lubricant composition of claim 1 , wherein the lubricant composition comprises about 75-96 wt. % of the oil component.
