| description | A lubricant additive concentrate having a kinematic viscosity of from about 40 to about 300 cSt at 100°C, containing a dispersant-detergent colloid complex, including a polybutenyl succinimide dispersant that is the reaction product of a polyamine and polybutenyl succinic anhydride (PIBSA) derived from polybutene having a number average molecular weight (M n) of from about 1300 to about 2500 and a terminal vinylidene content of at least about 65%, and succinic and/or maleic anhydride via an ene maleation process, the PIBSA having a succinic anhydride (SA) functionality (F) of greater than 1.7 and less than about 2.5; and a detergent colloid including overbased detergent having a total base number (TBN) of from about 370 to about 1000 mg KOH/g derived from one or more surfactants selected from (i) sulfonate; (ii) phenate; and (iii) carboxylate surfactant; in which the mass ratio of the dispersant to the overbased detergent colloid in the concentrate is from about 0.5 to about 5.0; and the dispersant and overbased colloidal together constitute at least 28 mass%, of the concentrate.
Un concentré dadditif de lubrifiant comprend une viscosité cinématique denviron 40 à 300 cSt à 100 °C contenant un complexe colloïde dispersant-détergent comportant un dispersant de succinimide de polybutényl qui est un produit de réaction danhydride succinique de polyamine et de polybutényl (PIBSA) dérivé de polybutylène ayant une masse moléculaire moyenne numérique (M n) denviron 1 300 à environ 2 500 et une teneur en vinylidène terminale dau moins 65 %, et un anhydride succinique et/ou maléique au moyen dun procédé de maléation-ene, le PIBSA ayant une fonction (F) danhydride succinique plus grande que 1,7 et plus petite quenviron 2,5; et un colloïde détergent comprenant un détergent surbasique ayant un indice de base denviron 370 à 1 000 mg KOH/g dérivé dun ou plusieurs agents de surface sélectionnés parmi (i) un sulfonate, (ii) un phénate et (iii) un agent de surface carboxylate, dans lesquels un rapport de poids du dispersant et du colloïde détergent surbasique dans le concentré est denviron 0,5 à 5,0; et le dispersant et colloïde surbasique représentent ensemble 28 % masique du concentré. |
