ADDITIVE CONCENTRATES FOR THE FORMULATION OF LUBRICATING OIL COMPOSITIONS |
| 摘要 |
A lubricant additive concentrate containing 30 to 80 mass % oil of lubricating viscosity and from 20 to 70 mass % of additive; wherein from 30 to 90 mass % of the additive is (i) hybrid overbased colloidal detergent derived from sulfonate surfactant and hydroxybenzoate surfactant; and (ii) polyalkenyl succinimide dispersant derived from a polyalkene having a number average molecular weight (Mn) of from 1300 to 2500 daltons, and wherein the mass ratio of polyalkenyl succinimide dispersant (ii) to hybrid overbased colloidal detergent (i) in the lubricant additive is from 25:1 to 1:1. |

1. A lubricant additive concentrate comprising from about 30 to about 80 mass % oil of lubricating viscosity and from about 20 to about 70 mass % of additive; wherein from about 30 to about 90 mass % of said additive comprises, on an active ingredient (AI) basis (i) hybrid overbased colloidal detergent derived from sulfonate surfactant and hydroxybenzoate surfactant; and (ii) polyalkenyl succinimide dispersant derived from a polyalkene having a number average molecular weight (Mn) of from about 1300 to about 2500 daltons; and wherein the mass ratio of said polyalkenyl succinimide dispersant (i) to said hybrid overbased colloidal detergent (ii) in said lubricant additive concentrate is from about 25:1 to about 1:1. |
