摘要： The present invention provides an engine oil composition including 70 to 95 percent by weight of a base oil and 0.01 to 15 percent by weight of a dispersant comb polymer, based on the overall weight of the engine oil composition. The dispersant comb polymer consists of 13.7% by weight of a macromonomer, which is an ester of methacrylic acid and a hydroxylated hydrogenated polybutadiene with Mn of 4750 g/mol; 51.5% by weight of n-butyl methacrylate; 17.3% by weight of LMA; 11.2% by weight of styrene; 0.2% by weight of methyl methacrylate; and 6.10% by weight of N,N-dimethylaminoethyl methacrylate. The modified dispersant inhibitor package contains 30 wt % or less of succinimide type dispersant based on the overall weight of the modified dispersant inhibitor additive package, and the engine oil composition has an SAE viscosity grade of 0W-X, wherein X is 30 or less.

摘要： The present invention relates to the field of lubricant, and specifically provides a lubricant composition and its preparation method and use. The lubricant composition comprises a base oil and rubber particles having radiation crosslinked structure dispersed therein, wherein the base oil is continuous phase and the rubber particles are dispersed phase. The viscosity of the lubricant composition of the present invention can be effectively adjusted as temperature changes. As compared with the lubricant composition comprising chemically crosslinked rubber particles, it has a lower viscosity at low temperatures and a higher viscosity at high temperatures, and has a relatively high viscosity index, which can meet the application requirements at the temperature above 200° C. In addition, the lubricant composition of the present invention also has excellent antiwear and friction-reducing properties.

摘要： An engine oil composition includes a star polymer (A) and a poly(alkyl (meth)acrylate) (B) as a viscosity index improver, and has a viscosity index of 185 to 230, the star polymer (A) having a star structure and having a weight average molecular weight of 100,000 to 1,000,000, the star structure being a structure in which polymer chains branch from a center of the polymer, the polymer chains being obtained by copolymerization and hydrogenation of an aromatic vinyl compound monomer and a conjugated diene monomer, the poly(alkyl (meth)acrylate) (B) having a weight average molecular weight of 200,000 to 600,000, the content (MA) of the star polymer (A) in the engine oil composition being 0.10 to 2.00 mass % based on the total mass of the engine oil composition, the content (MB) of the poly(alkyl (meth)acrylate) (B) in the engine oil composition being 0.50 to 6.00 mass % based on the total mass of the engine oil composition, and the ratio “MA/MB” being 0.10 to 1.00. The engine oil composition can significantly improve fuel efficiency, and is suitably used for a diesel engine.
