Lubricating composition and method for preparing same |
摘要 |
A composition made by admixing a major amount of base oils of lubricating viscosity and minor amounts of additives. The additives can include a viscosity modifier, a dispersant, a friction modifier, an anti-oxidant, a suppressant, a tackifier, and thickeners. The dispersant can be a dissolved powered styrene-ethylene/propylene-block copolymer and the thickeners can be fumed silicia. The dispersants and the thickeners are pulverized and dissolved in the composition to provide for inhibition of oil separation during storage. |

1. A composition comprising, or made by admixing: a major amount of: base oils of lubricating viscosity; and minor amounts of a viscosity modifier, a dispersant, a friction modifier, an anti-oxidant, a suppressant, a tackifier, and thickeners, the dispersant is a powered styrene-ethylene/propylene-block copolymer and the thickeners are (a) a hydrophobic fumed silica and (b) a hydrophilic fumed silica, the dispersants and the thickeners are pulverized and dissolved in the composition to provide for inhibition of oil separation during storage. |
