发明名称 MOTOR OIL ADDITIVE COMPLEX AND MOTOR OIL
摘要 FIELD: lubricants. ^ SUBSTANCE: additive complex contains 10-40% calcium C12-C24-alkylsalicylate, 5-15% high-alkalinity magnesium sulfonate, and, as the rest, interaction product of neutral and high-alkalinity calcium sulfonate with C12-C24-alkylsalicylic acid, neutral to-high-alkalinity sulfonate weight ratio being (5-20):(80-95). Complex may further contain alkylbenzene fraction with boiling range 300 to 600 and also zinc dithiophosphate and/or ash-free nitrogen-containing dispersant. Motor oil contains 3-15% additive complex, 0.003-0.05% polymethylsiloxane, and to 100% petroleum and/or synthetic base oil. Oil may further contain, wt %: zinc dithiophosphate 0.4-2.5 and/or ash-free nitrogen-containing dispersant 1.0-3.0, depressant 0.1-3.0 and/or thickener 0.1-3.0. ^ EFFECT: increased colloidal stability and antioxidant properties of additive complex and improved performance characteristics of motor oil used in gasoline and diesel engines. ^ 7 cl, 3 tbl
