▎ 摘 要
NOVELTY - Lubricating oil comprises 18-25 wt.% polyol esters, 8-10 wt.% alkyl naphthalene, 26.3-40.75 wt.% additive, and remaining of poly- alpha -olefin. USE - As lubricating oil. ADVANTAGE - The lubricating oil has stable anti-wear performance which exceeds 15% of the requirements of ACEA E6 standard, excellent engine cleanliness performance which exceed 36% of API CI4 standard requirement and high viscosity stability which can exceed 8 times that of APICI4 standard, reduces formation of deposits, does not contain corrosive substances, does not cause harm to environment, and is not harmful to mechanical equipment and not flammable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the lubricating oil, which involves taking raw materials, subjecting the raw materials to high-pressure homogenization in a high-pressure equipment, and high-speed shearing in high-shear equipment to fuse the molecules of the raw materials.
